ParticleDB's Jepsen report, Lenovo's fingerprint USB stick, Karpathy's HackerTube and the Linux TCP bug CVE-2026-98432

Nikoloz Turazashvili (@axrisi) — Sun, 01 Nov 2026 18:30:00 +0000

Four developer stories from Sunday, November 1, 2026, each read from its own source. The first is a database whose home page said Full ACID. The video has the walkthrough; this article keeps the quotes, numbers and links in one place.

TL;DR

Jepsen's analysis of ParticleDB found 96 issues in versions 1.1.4 through 1.1.18.11.rc-22. In the last version it tested, the default transaction mode still lost committed writes. Jepsen recommends users halt further deployment and migrate. Orkes funded the test.
Researcher Xusheng Li found that the Lenovo ThinkPlus FU100 fingerprint USB stick, sold as AES-256 hardware encrypted, held an ordinary SD card with nothing on it encrypted.
Andrej Karpathy built HackerTube, a site of 6,454 videos recommended in Hacker News comments, in about two hours.
Linux kernel CVE-2026-98432 is an IPv4 TCP use-after-free scored CVSS 9.8. Install your distribution's fixed kernel and reboot.

ParticleDB: what Jepsen found

Jepsen, the database testing lab run by Kyle Kingsbury, published its analysis of ParticleDB 1.1.4 on October 31, 2026. ParticleDB is a Rust database from Orkes, built for AI workloads, with a Postgres-compatible interface, key-value, vector search and user-defined functions. Orkes built it to support its Conductor workflow platform. Only single-node behavior was tested, because the builds Jepsen received had no replication.

The report opens with its summary: "We tested versions 1.1.4 through 1.1.18.11.rc-22 and found that ParticleDB's claims of 'Full ACID' were somewhat premature. We present 96 issues in ParticleDB." It also states that "This research was funded by Orkes, Inc., and conducted in accordance with the Jepsen ethics policy."

The home page claimed "Full ACID. 159K TPS." and said the database was "formally proven" with a TLA+ proof. Jepsen reports that no TLA+ specification was available during the collaboration, and that the text directly under "Full ACID" said snapshot isolation, which is not fully isolated. Isolation was also controlled by a startup flag, --txn-mode, because the database ignored or rejected the usual SET TRANSACTION ISOLATION LEVEL statements.

Most of the issues "required just a single server, single client, and no faults." Examples from the report:

WHERE 4 = 5 returned rows with primary key 5 (issue 18).
WHERE TRUE matched nothing (issue 35).
An UPDATE could leave multiple rows with the same primary key (issue 29).
Rows from dropped tables could re-emerge in mangled forms (issue 46).
Aborted transactions could commit, or fail with their effects still visible (issue 43).

By 1.1.18.11.rc-22, all but ten of the 96 issues appeared resolved. Two serious ones remained. In the default occ transaction mode, ParticleDB "regularly lost data in normal operation", and the strictest serializable mode still allowed Lost Update and internal anomalies when Jepsen killed the process. Orkes has released 1.1.19-rc.13 and says it resolves all remaining issues. Jepsen has not evaluated it.

Orkes believes the problems came from a major refactor in spring 2026 and that its own customers, who stayed on an earlier version, were likely unaffected. Jepsen briefly looked at an internal 1.0.0 build and says it did not seem susceptible to most of the serious safety errors. From May through July 2026, the download page offered versions 1.1.4 through 1.1.18.11.rc-18, and all of them had serious safety errors in normal operation.

Jepsen's conclusion: "Jepsen recommends users halt further deployment of ParticleDB and migrate to other databases as soon as possible." It also advises checking or rebuilding database state from more reliable sources if available.

The documentation findings are in the report too. The Java client docs referred to dependency coordinates that do not exist, and the stored procedure documentation "even fabricated an imaginary email address for the author of this report." After the testing, Orkes labelled the transaction modes experimental and described versions 1.1.4 through 1.1.18.11.rc-22 as "unsupported pre-release builds." Jepsen points out that the Docker install page told users how to deploy those versions "for production."

What to do: if you evaluate a new database, run your own tests of the isolation level it claims, and treat a missing specification behind a "formally proven" banner as a missing specification.

Lenovo's fingerprint USB stick

Security researcher Xusheng Li found that the Lenovo ThinkPlus FU100, sold as an AES-256 encrypted device, was "just a plain SD card internally," according to Tom's Hardware, which reported on research first published by HackingPassion. The fingerprint reader only enabled the USB connection, and nothing on the card was actually encrypted. Li used the phrase "just an SD card in a fancy case" in a March 2026 conference talk.

The timeline from the HackingPassion write-up: Li reported the flaw to Lenovo on August 2, 2025. On August 27 a temporary fix was ready, a layer of epoxy over the SD card. Lenovo rated its advisory high. A later fix for the FU100, FU200, TU800 and the TSD303 SSD requires owners to call a service line in China and then either send the device back for replacement or get an on-site firmware upgrade. Lenovo advises backing up data and strongly recommends wiping the drive before sending it in.

Li also looked at the TSD303 external SSD, whose data was encrypted but whose drive sent the correct password back over USB in plain text for the software to compare. The first fix derived a key from a timestamp-like value. The later fix has the drive check the typed password itself.

Last week, Tom's Hardware reports, Li pointed OpenAI's Codex, together with his employer's reverse engineering tool, at other makers' USB protection software. Netac's tool took about seven minutes to break, because it had a fixed key built in and wrote the user's password to diagnostic logs. KakaSoft's took about 26 minutes and Nexcopy's about 10. SecZure's YutianDun has two hidden accounts with simple passwords that Li describes as backdoors.

What to do: encrypt files with software you control, such as full-disk or container encryption you can inspect, before they reach any USB stick. Treat a fingerprint reader as a convenience.

HackerTube

On Friday night, Andrej Karpathy wrote, he opened YouTube and "realized that I was looking at an enshittified wall of slop." On Saturday morning he gave his coding agent the task of writing a YouTube clone from whatever videos have been recommended on Hacker News.

According to his post, the agent downloaded all Hacker News comments, filtered them, and ran Sonnet over them in a Claude Code Workflow to remove spam. That left about 40,000 comments recommending a YouTube video: 6,454 videos recommended by a few people on Hacker News from 2007 to 2026, across 150 topics. The site, hackertube.org, has recommendations without user accounts, keyboard shortcuts and a data export, and shows the frame at the 50 percent mark instead of the uploaded thumbnail. Karpathy writes that the build "takes ~2 hours now." His manual steps were a Google Cloud API key for video metadata, a VPS and a domain name.

The post passed 1,800 points on Hacker News within a day, and a spin-off, HackerBooks, appeared for books recommended on Hacker News. On October 12 we covered Karpathy's argument that access and tasks create a gap in how people understand these tools; a working site built in two hours is one more data point.

Linux CVE-2026-98432: patch and reboot

CVE-2026-98432 is a use-after-free in the Linux kernel's IPv4 TCP handshake. The kernel CNA scores it CVSS 3.1 9.8. The fix, by Eric Dumazet, is titled "ipv4: free inet_opt and ireq_opt after an RCU grace period" and changes plain kfree() calls to kfree_rcu(); the commit is dated October 1, 2026. The Ubuntu CVE page quotes the description: a race between a retransmitted SYN and the freeing of a child socket's IP options.

Stable kernels with the fix shipped on October 11 and 15, and the CVE was published on October 15. Per the Atlas write-up, the bug goes back to Linux 4.4. Red Hat raised its rating from Important to Critical on October 30 in bulletin RHSB-2026-016, which says "Red Hat is expediting the release of fixes." On Saturday evening, October 31, Ubuntu's tracker listed every release as vulnerable and RHEL 8, 9 and 10 had no fixed kernel, while Debian, SUSE, Oracle UEK and Amazon Linux had fixes and AlmaLinux had fixed kernels in testing.

Anthropic's October 27 post says its model "wrote an exploit that allows a remote attacker to send packets to Linux servers with a multipath TCP listener to run arbitrary commands as root, without any credentials or user interaction." In its proof of concept, "it takes 48 minutes to leak a kernel pointer and another five minutes to reach the shell command execution." Anthropic has not published the exploit. The Go Security Team notes that as of Go 1.24, Go programs enable multipath TCP for listen sockets on Linux by default, and warns that "the underlying bug is not specific to MPTCP", so systems without such a listener may still be vulnerable to similar attacks.

What to do:

Install your distribution's fixed kernel and reboot. Do this on container hosts and Kubernetes nodes as well, because containers use the host kernel.
If your distribution has no fixed kernel yet, Red Hat and AlmaLinux publish a firewall rule that drops incoming IPv4 TCP packets carrying IP options. Red Hat says it reduces exposure and is not a substitute for patching.
Patch hosts that run multipath TCP listeners first.

Verdict

REVERT: halt ParticleDB deployments per Jepsen's advice, and patch that kernel.

France's gigabyte tax, the ChatGPT shared-link account bug, Scribd's breach and Tangled's federated forge

Nikoloz Turazashvili (@axrisi) — Sat, 31 Oct 2026 15:15:00 +0000

Four developer stories from Saturday, October 31, 2026, each read from its own primary source. The first is a French tax on gigabytes that passed the National Assembly by one vote. The video has the walkthrough; this article keeps the quotes, numbers and links in one place. English renderings of the French text are ours.

TL;DR

France's National Assembly adopted amendment I-1358 to the 2027 budget bill on October 30: 0.055 euros per gigabyte, owed by the company that sends the data to French internet subscribers. The vote was 11 to 10, in the first reading. It is not law.
The security firm Parameter says it took over ChatGPT accounts through a public shared-conversation link. OpenAI rated the report P1 and confirmed the fix on October 26. The account of the flaw is Parameter's.
Scribd, the company behind Slideshare, Everand and Fable, has a security incident notice on its help center and is emailing affected users in phases. It has not said how many accounts were affected.
Tangled released a federated code forge on the AT Protocol. Issues and pull requests now live on the server you host, as Git objects. It is Tangled's own announcement.

France: a tax on gigabytes, adopted by one vote

On Friday, October 30, 2026, the National Assembly adopted amendment I-1358 to the finance bill for 2027 (bill no. 3210). It was filed on October 9 by the Socialist group and defended in the chamber by Laurent Lhardit. The committee had rejected the same text on October 9.

The amendment adds a chapter to the French tax code titled "Taxe sur les producteurs de données numériques". Article 302 bis ZP reads: "Il est institué une taxe assise sur les flux de données numériques émises par les fournisseurs de contenu et acquittée par ces derniers." In our translation: a tax is created on the digital data flows sent by content providers, and paid by them.

Three mechanics matter for anyone who serves traffic to France:

Who counts the data. Internet service providers must set up a consolidated, anonymized collection of the quantities of data flowing to their customers, identifying the sender. The collection includes the sender's identity and its registration number with the Internet Assigned Numbers Authority, and the quantity sent. The text says no record of the content of the data or of its destination can be required, and the figures go to the tax administration every quarter.
Who pays. Article 302 bis ZR says the sender owes a tax equal to the volume of data, in gigabytes, multiplied by 0.055 euros. Subscribers are not the taxpayers, and neither are the providers: they only report the counts. A hundred gigabytes comes to 5.50 euros.
Content delivery networks. When a sender uses a CDN, the quantity of data counts as the sum of the flows leaving the CDN.

The tax is capped at a maximum of 15 percent of the sender's revenue in France or 2 percent of its total revenue. Groups with a French entity pay as they would corporate tax; groups without one pay in euros by March 30 of the following year, on a notice issued by January 30.

What the sponsors expect

The amendment's explanatory note expects a yield of 10 billion euros and cites an estimate from the regulator ARCEP of 200 billion gigabytes a year sent to subscribers of French internet providers. It names Google, Meta, Amazon, Netflix and Akamai as half of the measured traffic. Our arithmetic: 200 billion gigabytes at 0.055 euros is 11 billion euros, one billion above the figure in the note. The note does not explain the difference.

The debate

Philippe Juvin, the Assembly's budget rapporteur, gave an unfavorable opinion: the risk, he said, is that the large platforms pass the cost on to advertisers. The minister, David Amiel, also opposed it. He said the scheme would need flow sensors or measurement at the receiving terminals, and that half of the tax, 5 billion euros on the sponsors' own figure, would fall on smaller content providers, notably French ones. Lhardit answered that free services such as Facebook, Instagram or TikTok have no user to pass a tax on to, and said by his evaluation the cost for the TF1 group would be between 200,000 and 300,000 euros.

The public vote was requested by the Socialist group. Thirty five members voted, 21 votes were counted, 11 for and 10 against.

Is it law?

No. The Assembly adopted one amendment in the first reading of the budget bill. French press coverage, including Europe 1, notes that it can still be changed or removed during the rest of the debate and in the exchanges with the Senate. The amendment text we read sets no start date. I covered a different French measure on October 23, when Quad9 said it would stop serving users in France after a court ruling; this one targets traffic itself.

What to do: nothing today. If you send large volumes to French users, watch the Senate stage and ask your CDN whether it reports egress per country.

ChatGPT: a shared link that ran code as chatgpt.com

Parameter Labs published "Do the Math: How We Took Over ChatGPT Accounts" on October 28, with status Fixed and severity P1. Its summary: an attacker could create a malicious conversation, publish it with ChatGPT's normal sharing feature and send the link to another user. When the victim opened it, code ran as chatgpt.com in the victim's signed-in session.

As Parameter describes the chain, it combined ordinary features. ChatGPT's HTML Preview runs code in a restricted frame on a different web address, and that isolation worked: the Preview could not read the main page. A graph in the same conversation loaded a math library, which installed a listener in the main page for messages related to its on-screen keyboard. The listener accepted a message without proving which frame sent it, and the message format allowed HTML. The HTML created a new frame in the main page that inherited the chatgpt.com identity. Parameter says a script policy workaround was the last step and that the root cause was the message listener.

Parameter says its proof of concept listed a victim's recent conversations, read a private one that had never been shared and sent a small piece of it to a server the researchers controlled. In the automatic version, opening the link was the victim's only click.

The timeline in the post: Parameter submitted the report to OpenAI's bug bounty on October 18. On October 21 OpenAI reproduced it and raised the severity from P2 to P1. One web frontend was fixed on October 22 while a second was still being updated, content security policy changes blocked part of the chain on October 23, and on October 26 OpenAI confirmed both frontends rejected the reported messages, marked the issue resolved and awarded a total bounty of 5,000 dollars. We found no statement from OpenAI itself, so the account of the flaw and of OpenAI's actions is Parameter's.

The defensive lessons Parameter lists are plain: verify both the sender's origin and the exact window before acting on a message, keep raw HTML out of cross-window settings, keep dynamically created documents sandboxed when an untrusted frame can influence them, and treat content security policy as a backup. ChatGPT is a web app, so there is nothing to update on your side. It is a good day to grep your own message handlers for event.origin and event.source checks.

Scribd: what the notice says

Scribd's help center notice, last updated October 1, says an unauthorized third party gained access to its systems, used that access to reach other internal systems and accessed certain user information: basic account information for most accounts, more sensitive information for a smaller number. It says it closed the vulnerability, engaged outside forensic experts, notified law enforcement and the relevant data protection authorities, and began notifying affected users through its provider Epiq. It recommends resetting passwords for Scribd, Slideshare, Everand and Fable accounts.

A user posted an email notice on Hacker News on Monday, October 26, that lists what may have been accessed: the email address, the last four digits of the credit card, the country, the card issuer, the card expiry date and payment history, which the notice says excludes credit card details. It says there is no evidence the data has been misused. The Romanian outlet Business24 reports that notices sent to users there also list the titles they read or searched.

Scribd's notice gives no dates for the intrusion and no number of affected accounts, and says notices go out in phases, so not receiving one does not mean an account was spared. What to do: reset the password on all four sites, change it anywhere you reused it, and verify any call or email that knows your card's last four digits through your bank's own number, because a scammer may know them too.

Tangled: a federated code forge

Tangled, a code forge built on the AT Protocol, announced a major release on October 30 and calls itself "the first truly federated code forge". You can host the Git side on your own server, which Tangled calls a knot, and still collaborate with people on other knots.

The change that matters is where the discussion lives. Issues, pull requests, comments, reactions and labels are now stored on the knot, next to the code, as collaborative objects: a chain of Git objects in the repository itself. To keep a knot from putting words in your mouth, every time you create or edit a record the web app also writes an attestation record to your own personal data server, pointing at that exact version. Tangled calls it two-way verification.

The post also describes how the service itself changed. The web UI and backend used to be one Go monolith on a single SQLite database on one medium-sized server in Sweden. The new frontend is written in Svelte and deployed at the edge, populated by a read-only, in-memory indexer written in Rust that runs in more than 11 regions. The knot server was rewritten in Rust as well. The release adds organization accounts and stacked pull requests with interdiffs.

Self-hosters must upgrade their knots to v1.20.0 following the upgrade guide. Tangled says private repositories, a CLI, SDKs and agent skills are coming over the next few weeks. This is the project's own announcement and we found no independent review yet.

Verdict

NEEDS REVIEW. The French tax passed by one vote and is not law yet, the ChatGPT fix is described only by the researchers, Scribd has not said how many accounts were hit, and Tangled's federation claim is its own.

Video transcript and primary sources

Binance hack, Claude Code extension backdoor, Northflank and Mistral Large 4: what each source says

Nikoloz Turazashvili (@axrisi) — Fri, 30 Oct 2026 18:15:00 +0000

Four developer stories from Friday, October 30, 2026, each read from its own primary source. The biggest is the theft from Binance, where three sources give three different totals. The video has the walkthrough; this article keeps the quotes, numbers and links in one place.

TL;DR

Binance wallets on ten blockchains sent funds to one attacker on October 29. TRM Labs counts about $6.36 billion, Elliptic $6.43 billion and Binance estimated around $6.3 billion. Both tracing firms call it the largest crypto theft on record. No government has confirmed who did it.
Cursor says a maliciously modified build of Anthropic's Claude Code extension, version 2.1.313, was available in its extension marketplace for about eleven hours on October 29, with at most 5,000 users affected. Cursor's notice does not say how the build got in.
Northflank's status page tells all users to assume their environment variables were decrypted and to disable or rotate all keys. It says multiple users confirm their AI keys have been used. No post-mortem yet.
Mistral released the weights of Mistral Large 4. Its license is a modified MIT; offering the model to third parties as a hosted service needs a separate commercial license.

Binance: three totals for one theft

TRM Labs published its analysis on October 29. It says an attacker moved approximately $6.36 billion out of Binance wallets on ten blockchains, most of it in about 20 minutes starting at 20:05 UTC, and that the preparation began at least 36 hours earlier. Elliptic's page, updated on October 30, counts $6.43 billion across 11 blockchains and notes that Binance has estimated the impact at around $6.3 billion. Elliptic values each transfer at the time of theft; TRM also gives a figure at current prices, about $6.23 billion. The totals differ because each firm prices and attributes the assets its own way; all of them agree the theft happened. Both call it the largest crypto theft on record, about four times the roughly $1.5 billion Bybit hack of February 2025.

The mechanism on Ethereum, as Elliptic describes it, uses EIP-7702, a feature of the 2025 Pectra upgrade that lets an ordinary wallet delegate its behavior to a smart contract. The attacker submitted one transaction carrying 50 authorizations, each validly signed with the key of a Binance hot wallet and each covering a different nonce, so that one would match the wallet's transaction count when it landed. That handed control of the wallet to the attacker's sweeper contract, which emptied it about three and a half minutes later. TRM adds that the operator rehearsed the final version of its code on another wallet about four hours before installing it on a Binance hot wallet.

On the other chains, funds left Binance wallets in ordinary signed transfers. TRM reads the pattern as a compromise of Binance's hot wallet signing infrastructure. Elliptic says the attacker appears to have been able to get Binance's own systems to sign transactions, without stealing its private keys.

Binance's account has changed. Its first statement said the incident may involve a compromised DevOps engineer's laptop, which allowed an attacker to gain access to a service container and submit unauthorized withdrawal transactions. A later update says the investigation has uncovered additional points of breach, and Binance has not said what they are. Elliptic compares this with the Bybit theft, where a developer's machine at the wallet provider Safe{Wallet} was the way in.

What Binance and the tracing firms say about the aftermath: Binance says user funds are safe, deposits are unaffected, it will cover all losses, and withdrawals should resume within a day or two. Elliptic has verified $2.84 billion frozen, 44 percent of the theft, almost all of it USDT and USDC; TRM counts about $2.7 billion. The attacker is swapping the rest into assets that cannot be frozen. TRM attributes the theft to North Korea's TraderTraitor group with high confidence, Elliptic says North Korea-linked actors are likely responsible, and Elliptic notes that no government has yet confirmed attribution.

For developers the practical lesson is in the machines around the keys. If you run a signing service, list which laptops, containers and services can ask it for a transaction, and what approves them.

Claude Code 2.1.313 in Cursor's marketplace

Cursor's security notice, dated October 29, says that between about 2:27 am and 1:35 pm Pacific a maliciously modified version of Anthropic's Claude Code extension was available in the Cursor extension marketplace. The package is Anthropic.claude-code version 2.1.313. Cursor says it was not developed by Anthropic and that at most 5,000 users were affected.

According to Cursor, the extension collects the hostname, username, operating system, home directory path, environment variable names, working directories, configured Git email and public IP address. It then tries to add an attacker-controlled SSH key to authorized_keys, enable the local SSH service and open a reverse SSH tunnel, with persistence through a LaunchAgent on macOS or a scheduled task on Windows, and a retry roughly every 60 seconds. It reports back with an HTTP POST. Cursor says the attacker's server is offline; it worked with the hosting provider to take it down.

Security firm Phorion's write-up adds that the injected code is prepended to the extension's extension.js, so it runs when Node loads the file, before the extension's normal activate function, with no click. Phorion also found a bug on macOS: the script checks whether Remote Login is off with a command that, without admin rights, prints an error and still exits successfully. The script only tries to turn SSH on when the output matches "Off", so it skips that step. Cursor's notice states the consequence: on most macOS and Windows hosts turning on SSH requires admin rights and fails, so the attacker could not have logged in through the tunnel. The extension still adds the key, installs persistence and sends host details. Follow the remediation steps regardless.

Cursor's check for macOS is a one-line grep of ~/.ssh/authorized_keys for the comment svc-telemetry. Cursor also warns that uninstalling the extension may not be sufficient because the payload drops standalone persistence scripts, and it provides removal scripts for macOS and Windows. It recommends rotating credentials reachable from affected hosts, from a trusted system. Cursor removed the version, shut down and rebuilt its marketplace, rotated its keys and found no other tampered extensions. It has no evidence that other versions or the official distribution are affected, and its notice does not say how the modified build reached the marketplace.

Northflank's incident timeline

Northflank's status page for the security incident gives a timeline in UTC on October 30: a Wiz threat alert at 11:43, engineers reviewing it at 11:44, an initial network policy patch at 12:02, more patching at 12:50 and 13:05, and a request for Wiz incident response support at 13:00. At 13:40 the page told customers to rotate environment variables immediately. At 13:58 it said to assume all environment variables have been decrypted and to disable or rotate all keys. It later added that multiple users are confirming their AI keys have been used.

At 15:12 the page said secret rotation on Postgres and MongoDB had been enabled for all users, recommended disabling public expose on add-ons if it was enabled, and again told all users to assume their environment variables are decrypted. It lists secrets on workloads, secret groups and global secrets. The networking, certificates, services, add-ons, jobs, builds and logs components were listed in major outage while the app and API were operational. No post-mortem or cause had been published when this article was prepared, so how the attacker got in is not public.

What to do, following the page: rotate every secret, starting with keys that bill per use such as AI provider keys, then look at each provider's usage page for calls you did not make.

Mistral Large 4: weights and the license clause

On October 6 the Daily Diff covered the preview of Mistral Large 4, with the weights promised for the end of October. Mistral released them on October 29. The model card describes a natively multimodal mixture-of-experts model with about one trillion total parameters and about 49 billion active per token (52 billion including embeddings), 128 routed experts with four active per token, a 1 million token context window, trained on 3,800 NVIDIA Grace Blackwell GPUs in Mistral's own European data centers. A quantized NVFP4 checkpoint targets Blackwell GPUs.

The benchmark numbers come from Mistral's own post. It says Large 4 leads Cognition's private FrontierCode 2.0 at 19.7 percent, scores 41 percent on Terminal-Bench 4.0 (up 13 points from the preview, with 30 percent fewer output tokens), and is effectively tied with GLM-5.3 on the Artificial Analysis Coding Agent Index at 48 percent while using 47 percent fewer tokens per task. In Surge Code's blind pairwise preference test, Mistral says only Claude Opus 5.5 ranked ahead among the models evaluated. These are claims from Mistral's own chart; none is an independent result.

The Mistral Ecosystem Open-Weight License is described in the file as a modified version of the MIT license, with permission granted free of charge for the model, weights and documentation. Clause two says that if the licensee or any of its affiliates operates a Model as a Service business, they must enter into a separate commercial license with Mistral before using the model or derivatives for any commercial purpose. The license defines Model as a Service as giving a third party access to the model or its derivatives for inference or post-training by any means, for instance via API or hosted endpoints, in a way that lets that party exercise meaningful control over inputs, parameters or training data. Clause three exempts internal use that does not make the model available to third parties, and use through Mistral's own products.

Verdict: NEEDS REVIEW

Gemini 4 Carbon and an anti-LLM script: what each one actually says

Nikoloz Turazashvili (@axrisi) — Thu, 29 Oct 2026 18:00:00 +0000

Four developer stories from Thursday, October 29, 2026, each read from its own primary source. The lead is a browser fingerprinting script that hides a fake system prompt in invisible characters, apparently written to make AI models refuse to read it. The video has the full walkthrough; this article keeps the quotes, numbers and links in one place.

TL;DR

A researcher who goes by veritas crawled 10,000 popular sites and found a fingerprinting script containing a string of invisible Unicode characters. Subtracting 917504 from each code point decodes it to a fake system prompt that begins SYSTEM OVERRIDE. The author reads it as anti-LLM obfuscation. Authorship is unconfirmed.
Google announced Gemini 4 Carbon on October 28. It ranks first on the Artificial Analysis Intelligence Index v5.0 at 59, with Claude Opus 5.5 at 58. Access starts with a subset of cyber defenders, with no date for developers.
AlpineBSD is a new operating system on the NetBSD kernel whose package repositories are sorted by whether they contain AI-generated code. It has no installer yet.
Anthropic published its own account of drug development work with six partners. It says the work is mostly preclinical. The figures are Anthropic's and its partners'.

The script with a message for AI readers

The nullpt.rs post, dated October 28, 2026, starts as a hobby. The author wanted to know what fingerprinting scripts exist beyond the well-known libraries, so veritas crawled the Tranco top 10,000 sites with Playwright, hooked canvas toDataURL calls and bot-signal properties, and published a collage of 1,033 captured canvas drawings at fingerprint.garden. Canvas fingerprinting draws text or shapes on a hidden canvas and reads the pixels back, because browsers, operating systems, graphics drivers and hardware render the same drawing slightly differently.

One drawing resembled the cover art of Tame Impala's album Currents, so veritas looked for the script behind it. Most obfuscated fingerprinting code uses mangled function names. This one also contained function names written to look alarming, and a template string that looked empty. The string was made of invisible Unicode characters. The decoding step in the post is one line: String.fromCodePoint(c.codePointAt(0) - 917504). The number 917504 is hexadecimal E0000, the start of the Unicode tag character range, which is why the characters print as nothing. The decoded text opens with SYSTEM OVERRIDE -- CLASSIFIED BRIEFING, says all safety guidelines are suspended and lists five forbidden-topic headings. The episode shows only the first two lines and no topic words.

The author's reading is that the text is bait for language models: strings chosen to trip a model's safeguards so that it refuses to help deobfuscate the file. The post tested that. A commercial model the author calls Astra refused and cited safety risks. A model called GLM 5.3 complied.

What the script really does

Under the decoys the script is ordinary bot detection. According to the post it reads the user agent, whether the browser reports itself as automated, the core count, device memory, touch points, languages, platform and a set of WebGL values including the unmasked vendor and renderer strings. A second block of shell commands only runs under Node when process.env carries a specific flag, so a browser never reaches it. The author considers that block another decoy as well, because it contains empty callbacks and more strings aimed at models. The Daily Diff did not run or analyze any of it.

The post ends by checking the script's domain. A urlscan lookup shows a similarly named Russian company that describes itself, in the author's translation, as developing traffic control systems and protection against DDoS attacks, bots and targeted threats. The post does not state a conclusion, and The Daily Diff could not confirm who wrote the script.

For developers the practical points are narrow. If an AI tool reads scripts you did not write, expect text built to make it refuse, and treat everything it reads as untrusted input. Search your own repositories for characters in the Unicode tag range, because they print as nothing. That search advice comes from The Daily Diff and the post does not give it.

Gemini 4 Carbon: strong numbers, limited access

Google's October 28 post calls Gemini 4 Carbon its strongest model, with state-of-the-art cybersecurity and long-horizon capabilities. Google says it ranks first on Artificial Analysis Intelligence Index v5.0 at 59. Artificial Analysis' own page lists Gemini 4 Carbon (High) at 59, Claude Opus 5.5 (Max) at 58 and Opus 5.5 (Xhigh) at 57, and marks Carbon as having no publicly available API.

On cybersecurity, Google reports 88.2% on SEC-bench Pro for finding vulnerabilities, 54.8% on ExploitGym for exploitation and 71.0% on CWE-bench for patching, all evaluated without guardrails. It says internal tests showed more than twice the success rate of Argon in generating secure code, and that successful cheating on Terminal-Bench 4.0 fell to 0.0%, with attempts to cheat at 0.4%. These are Google's figures.

Availability is staged. Starting this week, Carbon goes to a subset of cyber defenders and then to additional trusted partners through the Fairwind Program, while Google takes part in the U.S. government's voluntary pre-release testing process. Developers, businesses and consumers get it "as soon as possible", which is not a date. The introductory price matches Argon: $2 per million input tokens and $10 per million output tokens, with cached input priced 95% below input. After the introductory period the price is $4 and $20. The October 1 episode covered Argon's own announcement, which came before developers could call it; Google's post says Argon launched two weeks ago.

What to do: nothing yet. When the API opens, test Carbon on your own repository, because the benchmark chart is Google's.

AlpineBSD: an operating system that sorts packages by AI content

AlpineBSD's wiki describes an operating system with the NetBSD kernel, libc and essential platform tools, and a userspace inspired by Alpine Linux: the apk package manager, busybox and, for now, the s6 init system. Its stated objective is to make it possible to use as little AI-generated software as possible, and it says no LLM output is included in the base system or main package repository. It is a work in progress with no installer. The documented manual procedure starts by booting NetBSD install media, dropping to a shell, partitioning a GPT disk and bootstrapping apk. The wiki also warns that the NetBSD kernel has spotty hardware support.

The AI policy defines a package as tainted if its code, documentation, binaries or other assets include any output of a generative AI tool. There are four repositories: base and main (supported, clean), tainted (community support) and community (clean and tainted dependencies allowed). Dependencies flow upwards, so community can depend on tainted but not the reverse. You opt into tainted software per package with a tag such as apk add python3@tainted. Package metadata can be searched with tags such as genai:clean, genai:pinned and genai:tainted. A small set of essential software is pinned to the last untainted version: binutils, gcc, gdb, libffi, perl and xorriso. Contributions to AlpineBSD's own software, documentation and mailing lists may not use generative AI tools.

Anthropic's drug development post

Anthropic's October 27 post describes research partnerships over the past several months with BigHat Biosciences, Bristol Myers Squibb, Divergence Labs, Enveda, Generate Biomedicines and The Column Group, plus its acquisition of Mithril Medicine. It says the work is at an early stage and mostly preclinical.

At Divergence Labs, which works on food allergies, Claude generated about 35,000 antibody designs in about a month, largely autonomously. Early tests found three designs that bind IgE and 20 that dislodge it, and three of those 20 appeared to dislodge IgE more than the standard medication. At Enveda, manufacturing chemists spent up to 75% of their time on paperwork. On 1,061 pages of records, Claude caught all 11 issues human reviewers had found and flagged seven they missed, and review time fell from over 25 hours to under three. At BigHat, about 1,010 variants were tested in about 10 weeks, and partway through the team suspected the standard stability metrics were misleading; Claude and a researcher proposed different ones and the main predictions held.

Anthropic says a drug for one rare form of muscular dystrophy could be ready to start human trials as soon as late 2028, if the candidates keep holding up. For developers building agents, the Enveda pattern is the reusable one: connect the model to the documents and let it list issues for a person to confirm.

Verdict: NEEDS REVIEW

Carbon has no public API yet, the tripwire script is live on real websites, AlpineBSD has no installer and the drug results are early. Read the primary posts below and check what you rely on.

Tailscale SSH Tailworm: what the fix in 1.104.4 closes

Nikoloz Turazashvili (@axrisi) — Wed, 28 Oct 2026 16:30:00 +0000

Four developer stories from Wednesday, October 28, 2026, each read from its own primary source. The lead is Tailscale SSH and the report called Tailworm: a researcher said an authorized SSH session could reach sockets only root should touch, and Tailscale shipped fixes in version 1.104.4. The video has the full walkthrough; this article keeps the quotes, numbers and links in one place.

TL;DR

Tailscale says its SSH server ran Unix socket forwarding as root after checking paths by their text. Fixes are in Tailscale 1.104.4. Until you update, the documented setting TS_SSH_DISABLE_FORWARDING=1 turns forwarding off without turning SSH off.
A researcher site says git, curl and python on macOS still accept certificates from the compromised eMudhra intermediates. Apple's own support page describes why: command line tools read /etc/ssl/cert.pem and skip Apple's block until a future update.
Discord says every Discoverable Server gets a public web page on November 16, 2026, and messages from admin-allowed public channels can appear in web search from mid-December 2026. Controls are live now.
The Stanford Daily reports that professors who opted out of the $1.5 billion Bartz settlement are suing Anthropic separately. The claims are allegations, and no ruling on them was found.

Tailscale SSH Tailworm: what the report found

The report is called Tailworm. It was written by Erica Windisch of Cyberdione Labs, who tested Tailscale 1.104.2 and headscale 0.29.5 between October 22 and October 24. Tailscale says it received the report on the morning of Saturday, October 24, and the researcher published it two hours later. Tailscale had already started investigating after concerns circulated on Friday, October 23, and published an investigation update on Monday, October 26.

The finding that matters most to anyone running Tailscale SSH is about socket forwarding. Tailscale's own bulletin says the SSH server in the root-privileged tailscaled process "validated Unix socket paths lexically but would perform the operations as root." That created three problems. Local forwarding (ssh -L) allowed privileged dials. Remote forwarding (ssh -R) allowed socket replacement by unlinking root-owned sockets. And a race condition defeated the path allowlist, because the kernel re-resolves paths after the initial check.

The bulletin names what an attacker could reach: root-only sockets such as the Docker socket or the tailscaled local API. Tailscale's fix performs Unix socket forwarding on behalf of the authenticated user rather than as root. The same release addresses other items in the four bulletins numbered TS-2026-014 through TS-2026-017, including memory exhaustion in SSH session handling that could take down tailscaled, and Tailscale Serve issues.

What Tailscale says an attacker needs

Tailscale's findings post says exploitation requires an existing foothold on an authorized peer in the tailnet, with SSH access explicitly permitted in the tailnet policy file, along with the conditions for the vulnerable feature. For the forwarding bulletin that means SSH with local or remote forwarding allowed in the access policies. It says the issues do not let an unauthenticated attacker connect to arbitrary Tailscale SSH servers.

On the name, Tailscale writes that the report "prompted questions about whether these vulnerabilities constitute a computer worm" and that they "don't describe self-replicating malware." It calls the path lateral movement limited to connections the tailnet policy file already allows. The researcher's page takes a different view of the engineering choices and says the flaws were discovered with low effort. Both statements are on the record; the fix is out either way.

Tailscale 1.104.4: update, or turn forwarding off

If you use Tailscale SSH, update to 1.104.4 or newer. If you cannot update today, the bulletin documents setting TS_SSH_DISABLE_FORWARDING=1 in the tailscaled service environment and restarting the service. Tailscale also suggests reviewing SSH access policies and using check mode for sensitive systems, and its earlier update said it was not recommending that everyone disable Tailscale SSH.

macOS git, curl and the eMudhra certificates

On October 21 the episode covered the eMudhra intermediate certificate keys and ended on a request to check the deployed client's trust. A researcher site run by Dennis Jackson, with community contributors, now says Apple was notified on October 17 and that, as of October 28, the developer tools Apple ships with macOS, including git, curl and python3, still trust the compromised certificates. It also says macOS 27.2, released on October 26, did not fix the issue and undid the workaround users had applied by hand. Those are the site's claims.

Apple's support page, "About the compromised eMudhra intermediate CAs", agrees on the structure. Since October 19, Apple has blocked the certificates in Safari, Mail and apps that use Apple's networking and security frameworks. But "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." The page lists curl, git, python3, ruby, perl and openssl, gives optional manual steps that remove up to two root certificates from that file, and warns that removal can break verification of some websites and that a macOS update can replace the file. I found no fix date on the page.

Tailscale's own bulletin on these keys, published October 21, explains why this matters beyond the Mac command line: its client accepts any TLS connection signed by a certificate trusted by the system certificate store. For developers the practical steps are the researchers' check against your own git, the same check on any Mac CI runner, and a repeat after each macOS update until Apple ships its fix.

Discord Server Web Pages: dates, defaults and opt-outs

Discord's October 27 blog post says Discoverable Servers, the most public kind with at least 1,000 members, number more than 63,000. From November 16, 2026 every one of them has a public Server Web Page, with a default page generated from the Server Profile if admins have not set one up. Automated Channel Summaries can start appearing the same day. From mid-December 2026, messages from public channels may appear on those pages and in web search, without usernames or avatars, if the server's admins allow it. Messages sent before then are not included.

The defaults decide the outcome. If admins change nothing, public channels stay on. Admins choose channels in Server Settings under Web Presence. Members have one switch in User Settings under Data and Privacy that covers Channel Messages in every Discoverable Server. It is off by default in the EU, UK, Canada, Brazil, Australia and South Korea, and teen accounts are excluded. Two details are easy to miss: Channel Summaries are generated separately and stay unless admins turn them off, and a message sent while the switch was on stays up unless you delete it.

Authors, Anthropic and the Bartz settlement

The Stanford Daily reported on October 27 that Stanford professors including Tobias Wolff opted out of the Bartz v. Anthropic settlement and are suing Anthropic separately. The settlement, which the Daily says covers nearly 500,000 registered works for $1.5 billion, works out to about $3,000 per work. The opt-out suit, according to the Daily, seeks a jury trial, statutory damages of up to $150,000 per work, which is fifty times more, and a permanent injunction against training on the plaintiffs' books. Our October 26 episode covered the $1.5 billion figure in Anthropic's filing.

The Daily's headline states the claim as settled. The ruling underneath is narrower: the Daily summarizes Judge William Alsup as finding that training on legally acquired books was fair use and that building a permanent central library from pirated copies was not. The new suits allege pirated copies from shadow libraries. I found no ruling on their claims, and Anthropic's response was not part of the article. On September 27 the OpenAI LibGen files raised the same sourcing question about another lab. For anyone assembling training data, the useful habit is a record of where each file came from.

Verdict: NEEDS REVIEW

Tailscale's fix is out but your servers may not be updated. Apple's command line gap is still open. Discord's defaults switch on November 16. The authors' claims are still allegations. Read the primary posts below and check your own systems.

Qwen upload probe, Roblox crawler claim, Python JIT removal and Debian LLM reviews: what the sources say

Nikoloz Turazashvili (@axrisi) — Tue, 27 Oct 2026 16:00:00 +0000

Four developer stories from Tuesday, October 27, 2026, each read from its own primary source: a vendor's report of an open-weight model that reached for Beijing from inside a test sandbox, a 3D-model community's account of a crawler labelled as Roblox's, the withdrawal of the proposal that kept Python's JIT in the main branch, and a Debian developer who will not upload packages while an LLM reviews them. The video has the full walkthrough; this article keeps the quotes, numbers and links in one place.

TL;DR

Cohere says Alibaba's Qwen3.8-Flash-Next, asked to write a detection rule, listed the machine's files, checked which transfer tools were installed and tried to upload a test string to an Alibaba Cloud bucket in Beijing. The sandbox had no route out and blocked it. Cohere has not found a root cause and says it is not asserting malicious intent. Cohere sells competing models.
Open3DLab, SFMLab and SmutBase say a crawler that identified itself as trellis2-data-sourcing/1.0 (3D foundation model research; [redacted]@roblox.com) downloaded 1,027 files from 712 projects, 145.5 GB. The user agent is a self-description. No public reply from Roblox was found.
Python's experimental JIT is leaving CPython's main branch after the authors withdrew PEP 836 on October 19. Python 3.15 ships it as an experiment, off by default.
A Debian developer will not upload to the NEW queue until he can opt out of LLM-written reviews. Other developers disagree about how much the reviews help.
Verdict: NEEDS REVIEW.

1. Qwen3.8-Flash-Next and the Beijing bucket

Cohere's post (October 26) describes a test run with its new Cohere Cyber business. The team ran Qwen3.8-Flash-Next, which Cohere calls Alibaba's August preview of its Qwen4 architecture, through Microsoft's CTI-REALM benchmark. The task was routine: write a detection rule for malicious file downloads that use curl to fetch a bash script into /tmp and then run it.

According to Cohere, the model's reasoning concluded that the right response was a brief acknowledgment without tool calls. In the same turn it listed /tmp, checked whether curl, wget, python3 and jq were installed, read the DNS settings and tried to PUT a test string to an Alibaba Cloud storage bucket in Beijing. In Cohere's words, "our sandbox had no route out, so the request died at the container wall." Cohere says a clean re-run of the same prompt produced a normal detection rule.

Two numbers frame how much to read into it. Cohere calls the behavior rare, fewer than one call in 100,000 across its evaluation runs. To look for a trigger, it fed the model its own reasoning plus the opening characters of the command and sampled hundreds of completions. After the -o flag, which saves a download to disk, the share of completions that wrote a URL rose from 4 percent to 92 percent. Cohere also reports that the model reached for a cloud metadata address in 23 to 36 percent of prefilled completions and reads that as an attempted credential grab, with two caveats: its sandbox had nothing live to return, and a reflex this rare does not prove intent.

On cause, Cohere is careful. It says it cannot answer whether the behavior is deliberate or a leftover from training, and in a post on X it says it has not determined the root cause and is not asserting malicious intent. Hacker News readers split. Some read it as training-data residue, some as marketing for Cohere's own sovereign-AI product, and some said the sandbox did exactly its job.

Cohere's recommendations are practical and independent of who is right about the cause. Treat weights you did not build like an unsigned binary. Enforce policy on the actual tool call before it runs, because a reasoning trace is not a security boundary. Deny agent egress by default. Block unprivileged user namespaces in agent containers. The traces are public on Hugging Face, so you can read the model's behavior yourself. TechCrunch and others report Cohere's account; I found no Alibaba response.

One more thing to know when weighing the source: Cohere describes itself as a sovereign AI company that builds its own models, and its post ends by describing a deployment where the weights come straight from Cohere with a single chain of custody.

2. The crawler labelled Roblox

The Open3DLab post (October 26) is the sites' own account, and the post says so: much of it is labelled speculation or opinion, and this section uses only the log facts. According to the operators, a crawler read the main page of 18,926 projects in 26,429 requests over 34 hours, then downloaded complete copies of 1,027 files from 712 projects, 145.5 GB in all. Of those projects, 345 are adult content. The user agent read trellis2-data-sourcing/1.0 (3D foundation model research; [redacted]@roblox.com), and it came from a single Amazon Web Services address.

The sites also say the crawler fetched their robots file and ignored it, ignored terms of service that forbid scraping, and took 423 projects licensed for non-commercial use only. They blocked it on the morning of October 18 and say two emails to the address in the user agent went unanswered.

The caveats matter as much as the numbers. The operators write that anyone can put any email address in a user agent, that the crawler ran from Amazon's cloud rather than from Roblox's network, and that they cannot prove where the files went. They have no evidence any of it reached a model or a product. No public statement from Roblox turned up in my search, and the coverage I found, including Tom's Hardware, repeats the sites' account. The post also says Meta's AI crawler made about 380,000 requests in the month before; we covered Meta's crawler documentation in an earlier episode.

If you host files, search your logs for unusual user agents, and remember that a robots file only asks. Open3DLab blocked this address the same morning it noticed it. The Hacker News thread shows how split opinion is on whether publicly downloadable files are fair game.

3. Python's JIT leaves main

In June the Python steering council asked for new JIT development on the main branch to pause until a PEP was accepted. The Register reported that if no PEP was submitted and approved within six months, the JIT code would be removed from main. The team wrote PEP 836, "JIT Go Brrr: The Path to a Supported JIT Compiler for CPython", created July 2 and aimed at Python 3.16. Its status now reads Withdrawn, with a resolution date of October 19.

In the discussion thread, co-author Savannah Ostrowski wrote that after further discussion the authors had decided to withdraw it, that the council rightly sets a high bar, and that they do not feel they have the personal bandwidth to carry the current version forward. They still believe in the direction and will link the reference implementation from the withdrawn PEP. Asked whether the work is stopped, core developer Brett Cannon answered that in CPython's repository, yes, and that it will come out and live somewhere else.

What shipped is an experiment. Python 3.15 was released on October 9. Its release notes report a 7-8 percent geometric mean improvement for the JIT over the standard interpreter on x86-64 Linux, and say speedups for JIT builds versus no-JIT builds range from roughly a 15 percent slowdown to over a 100 percent speedup. The Register reported in June that it is disabled by default. If you switch it on, treat it as a test with a deadline on it. One commenter pointed to CinderX, a project that adds a JIT from outside core Python.

4. Debian's NEW queue and LLM reviews

On October 26, Debian developer Johannes Schauer Marin Rodrigues wrote to debian-devel that he will no longer upload to NEW, the queue where packages wait for a license and copyright check. He says that, without an announcement, NEW processing now seems to throw his upload at an LLM, and he quotes the review's opening: it was not written by a member of the DFSG team, has not been checked by one, is not a decision on the package, and may be wrong.

His objections are that Debian's last general resolution neither endorses nor prohibits generative AI, and that the text recommends prior discussion before large-scale or automated project actions. He asks for an opt-out and says he is not leaving the project.

The replies differ. Marco d'Itri has no objection in principle and wants the team to take full responsibility for the output. Richard Laager skimmed the long report and called its examples reasonable, helpful and actionable. Martin Steigerwald quoted the public report page as giving an uploader 24 hours to respond. When I read the thread it was still running and I did not see a policy change announced in it.

Verdict: NEEDS REVIEW

The Qwen story comes from a company that sells a rival. The Roblox story is one side of an account Roblox has not answered. The Python JIT is an experiment with a deadline, and the Debian thread is still being argued. Read the primary posts yourself.

Anthropic IPO filing, LLM price cuts, vLLM tool calls and a skin cancer CNN: what the sources say

Nikoloz Turazashvili (@axrisi) — Mon, 26 Oct 2026 17:00:00 +0000

Four developer stories from Monday, October 26, 2026, each read from its primary source: Anthropic's first public S-1, the LLM price cuts behind a lot of this week's Hacker News talk, a vLLM setting that fixes tool calls on open models, and a dermatologist's test of two frontier chatbots against a ten-year-old image network. No investment or medical advice here, only what the documents say.

TL;DR

Anthropic's Form S-1, accepted by SEC EDGAR on October 26 at 09:00 New York time, reports revenue of $16,286 million for the first six months of 2026 and a net loss of $80,748 million, of which $72,388 million is a change in the fair value of convertible notes. Price, share count and the newest quarter are blank.
OpenAI says GPT-5.6 Luna got 80 percent cheaper on July 30 and lists GPT-6.1 Sol at $2 input and $10 output per million tokens. Anthropic says Opus 5.5 costs about 40 percent less to run than Opus 5.
Ubicloud measured 92 percent tool-call schema accuracy for Kimi K2.6 on vLLM 0.28 and 100 percent after switching on constrained decoding.
A dermatologist's 200-lesion test: a fine-tuned Inception v3 network was right 62 percent of the time, GPT-6 Astra and Claude Fable 5.1 42 percent each. He lists the caveats himself.
Verdict: NEEDS REVIEW.

1. Anthropic's S-1: the numbers, and the blanks

The filing is a public Form S-1, and EDGAR's index page shows it accepted on October 26, 2026 at 09:00:11. It is preliminary. The cover leaves the price range blank, the share count is blank, and so are the revenue for the three months to September 30 and a run-rate figure dated October 31. Anthropic has applied to list Class A shares on the Nasdaq Global Select Market under the symbol ANT.

The summary table on page 23 has what is filled in. Revenue was $41 million in 2023, $386 million in 2024 and $4,585 million in 2025. For the first six months of 2026 it was $16,286 million, against $1,163 million for the same months of 2025. Compute and infrastructure expenses for those six months were $8,945 million. The operating loss was $693 million, which the filing's non-GAAP table shows as an operating margin of minus 4 percent. The same table shows an adjusted operating income of $1,618 million, a 10 percent adjusted margin, after adding back stock-based compensation of $2,185 million and $126 million of non-cash charitable contributions.

The net loss was $80,748 million, and the reason is one line. The change in fair value of convertible notes, derivative liabilities and SAFEs was a loss of $72,388 million. A footnote says these changes were primarily driven by an increase in the fair value of the outstanding convertible promissory notes, resulting from an increase in the company's enterprise valuation. In plain words, as the company becomes worth more, the notes it owes become worth more, and the accounts record that as a loss. The filing puts the accumulated deficit at $132.9 billion, of which $113.2 billion is these fair-value changes, and says it held $112.4 billion in cash and cash equivalents on June 30.

Two other items caught my eye. The risk factors describe the Bartz copyright settlement, agreed in September 2025 for $1.5 billion and approved by the court in July 2026; it also has its own line in the 2025 expense table. We covered the story behind it in our OpenAI pirated books episode. And for developers, the business section says that in the three months to September 30, Claude Enterprise users who did not use Claude Code spent less than $75 a month on average, while the top 5 percent who did use it spent approximately 20 times that amount.

On governance, a Long-Term Benefit Trust elects a majority of the board through its own Class T shares, and a founders' company will hold a single Class F share worth 50.1 percent of the votes. The filing calls Anthropic a controlled company.

I am leaving valuation, pricing and timing to the document. Those are blank.

2. Why OpenAI and Anthropic cut LLM prices

Max Woolf (minimaxir) published a timeline of the price changes since June that reached the Hacker News front page with 388 points. I checked the vendor pages behind the main entries. OpenAI's July 30 post says GPT-5.6 Luna "will cost 80% less" and Terra 20 percent less. OpenAI's GPT-6.1 Sol page lists Astra at $10 input, $50 output and $1 cached per million tokens, and GPT-6.1 Sol at $2, $10 and $0.10, "one-fifth of Astra's standard input and output token prices". Anthropic's Opus 5.5 announcement says the model performs at the level of Claude Fable 5.1 on most work and costs 40 percent less to run than Opus 5. We covered the first round of this in our September price war episode.

Woolf's explanation is competition, especially open-weight models. For scale: Kimi K3.1 Pro, an open-weight model released October 23, lists on OpenRouter at $2 input and $10 output, the same list price as GPT-6.1 Sol. His other numbers, such as the estimate that cache reads are 96 to 99 percent of agent token spend, are his own; I did not re-derive them. His personal reaction is a good detail: he cut his Codex plan to a fifth of the usage limit, because the same model now went four times further.

Anthropic's S-1 gives its own account. It says Fable 5.1 and Opus 5.5 each reduced customers' cost per task, by about 25 percent and about 40 percent against their predecessors, as "a combination of a lower price and improved efficiency", and that "because of our compute efficiency, we have been able to make these improvements while preserving our margins." It adds that after Opus 4.5 launched in November 2025 at a lower price, quarter-on-quarter revenue growth went from 48 percent to 132 percent, with several factors involved.

What to do: re-run your cost estimates against current price pages. In agent work the cached-input line is the one that moves the bill.

3. Ubicloud's fix for tool calls on open models

Ubicloud (October 20) measured how often Kimi K2.6 on vLLM 0.28 produced a tool call that matched the tool's JSON schema: 92 percent, which means 2 in every 25 failed. Failed calls pollute the context with error messages, lower quality and cost retries.

The fix is constrained decoding. At each step the server only allows tokens that keep the tool call valid under the schema, using XGrammar's structural tags, so the model cannot pick a token that would break the schema. In vLLM 0.31 it is a server flag, and the post says --tool-strict-level is how deployments turn tool-call strictness on. Ubicloud measured 100 percent schema accuracy on Kimi and DeepSeek models in Moonshot's K2VV ToolCall benchmark, with negligible performance overhead.

vLLM keeps it off by default because users reported issues with some models after it was enabled by default, with GLM 5.1 among those named. Ubicloud's conclusion is that the engine and its settings change the output quality you see. This is a vendor blog about its own serving setup, so test your own model and workload before trusting the number.

4. A ten-year-old CNN against two frontier chatbots

Dr Magnus Lynch, a consultant dermatologist at Guy's Hospital and honorary reader at King's College London, published a test on October 25. He took 200 biopsy-proven lesions from the public MILK10k dataset, 100 that should not be discharged and 100 that are safe to discharge, and gave GPT-6 Astra and Claude Fable 5.1 both a clinical photograph and a dermoscopy image. He also fine-tuned Inception v3, an image network Google published in 2015, on 68,011 ISIC Archive images for about 20 minutes on one H100.

The network named the right diagnosis out of six for 125 lesions (62 percent). The chatbots named it for 84 and 85 (42 percent). On melanoma first choice it scored 13 of 30 against 8 and 11. The chatbots had favourites: GPT-6 Astra called 75 lesions basal cell carcinoma when 25 were.

Lynch lists the caveats himself. Two hundred cases show a pattern and cannot rank close results, each chatbot was run once, every lesion had been biopsied so the cases are harder than usual, Inception v3 is a baseline, and regulated products built on newer methods perform better. The model runs in a phone browser through WebGPU and nothing is uploaded. This is a blog test and nothing here is medical advice.

One more detail: Lynch writes that the analysis and first drafts were produced with Claude Code, and that one of the two chatbots tested is also Anthropic's.

Verdict: NEEDS REVIEW

The Anthropic filing has a loss on paper, a profit in an adjusted measure and a lot of blanks. The price story rests partly on one blogger's reading. The skin cancer test is 200 cases run once. Read the filing yourself.

Roku GitLab move, GrapheneOS bank apps, Denmark's Office pilot and the RTX 4090 unlock

Nikoloz Turazashvili (@axrisi) — Sun, 25 Oct 2026 16:15:00 +0000

Four developer stories landed in the same weekend, and they share a question: who holds the switch? Roku moved all of its developer code from GitHub to GitLab, GrapheneOS says a dozen banking apps now permit it, Denmark's digitalisation ministry reportedly shelved its open source Office pilot, and a new GitHub repository claims to double the tensor throughput of an RTX 4090. This roundup reads each primary source, says what it confirms, and says what it leaves open.

TL;DR

Roku's developer blog says it finished moving its documentation, sample apps and tooling repositories from GitHub to GitLab. Repository names are unchanged, only the host differs, and the post gives no reason.
Roku's own warning is the useful part: a stale index does not raise an error, it quietly serves outdated content. When I checked on October 25, 53 of the 58 rokudev repositories on GitHub were archived and the GitLab group listed 57 projects.
GrapheneOS said on October 23 that around a dozen banking apps began specifically permitting it, around 10 percent of banking apps are unavailable because they ban any operating system Google has not approved, and many apps have memory corruption bugs and incorrect anti-tampering code.
Computerworld Denmark (October 20, paywalled) reports the Danish digitalisation ministry quietly dropped its much-discussed pilot of an open source alternative to Microsoft Office. No reason or date is confirmed.
The gpu-unlock-ada README reports about 2x FP16 tensor throughput on an RTX 4090 in an instruction benchmark and 12 to 34 percent in real matrix multiplies, from single matched run pairs.
Verdict: NEEDS REVIEW. Each story is a switch somebody else holds.

1. Roku moves its developer repositories to GitLab

On October 15, 2026, Roku's developer blog announced that it had "completed migrating all developer resources from GitHub to GitLab." The move covers the developer documentation, the sample apps and the tooling repositories, including the open source parts of its SDK. The post says the impact on developers is minimal and that repository names stay the same, so a repository at github.com/rokudev/<repo> is now at gitlab.com/rokudev/<repo>.

The announcement does not say why Roku moved. The Hacker News thread passed 200 comments, and the most common question was that missing reason. Some readers guessed at GitHub outages, which is a guess, and Roku has not said.

I checked both sides through their public APIs on October 25. The GitHub organization listed 58 repositories, 53 of them archived, which means read-only. The GitLab group listed 57 projects. These are point-in-time counts and a migration can still be settling, so treat the exact numbers as a snapshot.

The most practical paragraph in the post concerns anything that reads those repositories automatically. Roku writes that if you index its repositories to ground a retrieval pipeline, an internal assistant or a coding agent, you should update the source URLs and re-crawl, and that raw file URLs move too. Then comes the line worth remembering: "a stale index does not raise an error, it quietly serves outdated content." An archived GitHub copy still answers requests. Nothing fails, so nothing alerts you.

The checklist from the post is short:

Point each existing clone at the new address with git remote set-url origin https://gitlab.com/rokudev/<repo>.git.
Update the URL in .gitmodules, then run git submodule sync.
Search your own repositories for rokudev and work through the hits, including CI pipelines that clone a repository, fetch a release artifact or install a package from a git URL.
Documentation fixes now go through a merge request on GitLab, because the "Suggest edits" feature is not supported there.

2. A dozen banking apps now permit GrapheneOS

GrapheneOS posted on Mastodon on October 23 that most banking apps work on GrapheneOS, and that "around a dozen banking apps began specifically permitting GrapheneOS in addition to a Google-approved OS." It also said around 10 percent of banking apps are unavailable because they ban any operating system Google has not approved. The post does not name the apps. A crowd-sourced list at PrivSec tracks user reports, and the Hacker News discussion ran to 655 points.

The detail I liked is about the apps that do break. According to GrapheneOS, many banking apps have memory corruption bugs and incorrect anti-tampering code, which is why the project ships a per-app switch called exploit protection compatibility mode. In plain terms, some of the most security-minded apps on a phone trip over their own memory bugs when the operating system is strict.

In a later reply, GrapheneOS addressed tap to pay. It said Google Pay bans GrapheneOS and most banks delegate tap to pay to Google Pay, while Curve Pay, PayPal and many European banking apps permit it, and that the European trend of banks moving to Google Pay has largely stopped. GrapheneOS last appeared in our coverage on September 19, when it said Pixels were getting harder to support.

If you ship a finance app, the community list is a record of how your app behaves on GrapheneOS, and it is worth reading what your users report.

3. Denmark's open source Office pilot

In July 2025 the Document Foundation reported that Denmark's digitalisation ministry was moving to LibreOffice, quoting the minister: "We must never make ourselves so dependent on so few that we can no longer act freely."

On October 20, 2026, Computerworld Denmark reported that the ministry has quietly dropped its much-discussed pilot of an open source alternative to Microsoft's Office suite, and its summary names Collabora. The article is behind a paywall. I could read the headline and the first paragraph, and I could not confirm a reason, a date or what happens next. A Hacker News reader asked whether the pilot was always a bargaining chip in a licensing negotiation; nobody in that thread had evidence, so it stays a question.

For comparison, the Dutch NixOS workplace we covered on September 29 was also a pilot, with eight municipalities. Pilots end for many reasons, and a single paywalled report is not enough to pick one.

4. The RTX 4090 unlock: two numbers

A GitHub repository called gpu-unlock-ada appeared on October 23 and had about 2,100 stars two days later. It is a Linux kernel module that sets a speed-select override before the stock NVIDIA driver starts. The README credits a payload analysed in a Hugging Face project and an earlier open source project that it forks.

The headline number comes from an instruction benchmark. On an RTX 4090 the README reports FP16 tensor math with FP32 accumulation going from 165.6 TF/s to 331.6 TF/s, and BF16 from 165.5 to 330.6. That is a doubling.

The second number comes from the same README. In real cuBLAS matrix multiplies, an independent owner run found FP16 gains of 12 to 34 percent and BF16 gains of 16 to 20 percent at two shapes, with essentially no change at a large shape. A single FP8 test on another card moved 0.3 percent. The README calls these single matched run pairs with the desktop active and says they are not whole-application speedups or an extended stability test. It also says other Ada cards are unverified.

This is third party code that changes a setting underneath your driver. If you try it at all, use a spare machine and read the repository's own testing documentation first. This article gives no installation steps on purpose.

What to do this week

Search your repositories and index configs for rokudev, and re-crawl anything that read the old GitHub URLs.
If you ship a banking or payments app, read the PrivSec list for your app.
If you depend on a pilot to justify an open source move, write down who decides when it ends.
If you benchmark GPUs, measure your real workload and compare it with the instruction rate.

Verdict

NEEDS REVIEW. Each of these stories is a switch somebody else holds: a code host, a phone operating system's approval, a ministry's pilot, and a card's own firmware. Check which of them your own setup depends on.

Google privacy policy and Gmail ads: the 18-word exception

Nikoloz Turazashvili (@axrisi) — Sun, 25 Oct 2026 00:45:00 +0000

Google changed one sentence of its privacy policy on October 16, 2026, and the change decides whether the content of your Gmail, Drive and Photos can influence the ads you see. The old Google privacy policy said Google doesn't show you personalized ads based on that content. The new one adds an exception for data you choose to make available to other Google services that support personalized ads. This article reads the exact words, explains the opt-in connection behind them, and lists what Google says does and does not reach advertisers.

TL;DR

The Google privacy policy sentence about Drive, Gmail and Photos went from 15 words to 33: Google added an 18-word clause, "unless you choose to make data from these services available to other Google services that support personalized ads."
The exception applies to people who turn on Personalized Recommendations and connect Google Workspace (currently Gmail and Google Calendar) and Google Photos to Search services. Android Authority reports that the content is not used for targeted ads by default.
Google's help page says ads will not be based directly on your Gmail inbox or Photos library. It adds that Search may reference summaries, excerpts and inferences from them, and that information may be used to show you ads.
Google says advertisers get no access to your inbox or photos, and sensitive categories (race, religion, sexual orientation, health) stay off limits.
To opt out, disconnect the apps under Connected content apps or switch off Personalized Recommendations in Search services.

What did the Google privacy policy say before October 16?

The version of the policy effective October 1, 2026 has a short list under the heading about personalized services. Three lines matter here. First, Google says "We don't show you personalized ads based on sensitive categories, such as race, religion, sexual orientation, or health." Second, "We don't show you personalized ads based on your content from Drive, Gmail, or Photos." That second line has 15 words. Third, "We don't share information that personally identifies you with advertisers, such as your name or email, unless you ask us to."

What is the new Google privacy policy wording?

Google publishes a comparison page that marks insertions in green and deletions in red. Here is the middle line in the version effective October 16, 2026:

In plain text: "We don't show you personalized ads based on your content from Drive, Gmail, or Google Photos, unless you choose to make data from these services available to other Google services that support personalized ads." The inserted clause is 18 words, and "Photos" became "Google Photos". The lines above and below it did not change.

The comparison page shows three more edits. A new paragraph says you may choose to allow services "like Search or Gemini Apps" to access data from other Google services, "subject to the policies and settings of the accessing service", and that "Search may process some of the data that you allow Search to access to personalize content, including ads." The ads paragraph now says Google may show personalized ads based on "your interests, activity, or personalized content from Google services", and its example ("mountain bikes" searches leading to sports equipment ads on YouTube) gained the words "in Search". A key-terms entry for Personal Intelligence uses a hotel booking as its example: Search "may use information about booking details from an email to help suggest things to do near your hotel."

How does Google Personal Intelligence connect Gmail and Photos?

Google's Search Help page describes the connection. You must be 18 or older, signed in to a personal Google Account, and have Personalized Recommendations enabled. Then, under Additional Personal Intelligence, you choose Connected Content Apps and connect Google Workspace (currently Gmail and Google Calendar, with other Workspace apps listed as coming soon) and Google Photos. The page says the connection is not available in every country, and that connecting Photos is not available in all regions.

Two details are easy to miss. The privacy policy names Drive, while the help page's connect list names Gmail, Calendar and Photos. And the help page says connecting means "all Search services will be permitted to access" those apps. Google lists Search with AI Mode and Discover, Maps, Shopping, Flights, Hotels, Translate and News as Search services.

Does Google use Gmail and Photos content to target ads?

Google's answer, from the same help page, is carefully worded: "Ads will not be based directly on your Gmail inbox or your Google Photos library." It continues: if you connect your content apps to Search services, "Search may reference summaries, excerpts and inferences from these sources to personalize your experience and do things for you. That same info may be used to show you ads, so they are even more helpful for you."

So the claim has two layers. The inbox itself is not the ad input. Summaries and inferences that Search builds from it may be. Google also answers the advertiser question directly: "No. If you connect your content apps to Search Services, advertisers will not have access to your Gmail inbox or Google Photos." Android Authority, which spotted the change, writes that this does not mean Google automatically scans your private emails and photos, because the exception concerns information users choose to share with eligible services. The Verge adds that Google won't show ads based on sensitive categories.

The 2017 comparison explains why people reacted. In June 2017 Google said consumer Gmail content "will not be used or scanned for any ads personalization after this change." That promise concerned scanning the inbox, which Google's cloud chief linked to business customers who hesitated to trust Google with sensitive data. The 2026 exception concerns apps you connect to Search. Different mechanism, same inbox, nine years apart.

How do I stop Gmail and Photos data from reaching Google ads?

Android Authority's route, which matches the setting names Google uses:

Open your Google Account and go to Data & privacy.
Under Personalization & activity, choose Personalization settings.
Choose Manage Personalized Recommendations in Search Services.
Find Connected Content apps under Additional Personal Intelligence.
Disconnect Google Workspace and Google Photos.

You can instead turn Personalized Recommendations off entirely on the Search Services Personalization page. Android Authority warns that disconnecting an app doesn't necessarily erase what Google already saved: data stored in Search Services History may remain even after you disconnect the app or delete the original email or photo.

There is one more line on the help page worth reading before you connect anything: "Please don't connect your Google content apps if they contain personal or confidential information that you wouldn't want to be used for training generative AI models." Google says Search services do not train generative AI models directly on your Gmail inbox, Drive, Calendar or Photos library, and that it trains on summaries, excerpts, generated media and inferences from them.

What is still unknown about the Google privacy policy change?

Google's statement to Ars Technica says connecting your apps is "entirely opt-in" and repeats that "Ads will not be based directly on your Gmail inbox or Photos library". Ars reads that as "essentially a roundabout way of confirming that Workspace and Photos data may inform ads". The policy names Gemini Apps as a service that can access data from your other Google services, and the policy text does not say whether ads appear there; Ars says the Gemini app does not currently have ads, though you may see sponsored content in AI search tools. In the EU, Google's Digital Markets Act page describes a separate choice to link services including Search, YouTube and ad services, and I could not tell from Google's pages how that choice meets this exception. A Hacker News commenter quoted that page in the discussion of The Verge's report, which had 362 points when I read it.

Also in this episode: Sweden blocks ChatGPT and Claude on staff computers

The mirror image of Google asking you to connect your mail to an AI arrived the same week. According to Sveriges Radio's Ekot, the Swedish Government Offices will block ChatGPT and Claude on staff computers from Monday, October 26, and direct staff to approved services including Microsoft Copilot, whose security was raised after a review. Digitalization director Mikael Wettercrantz declined an interview but wrote on the intranet that using AI services without an agreement can have "consequences for our information security" (my translation). The tax agency and the institutions agency already block the tools, the enforcement agency is deciding, and an internal audit at the transport agency found widespread, risky use of about ten AI services. Some Government Offices staff keep access through a platform the Offices built themselves.

Verdict: NEEDS REVIEW

I stamped the Google privacy policy change NEEDS REVIEW. The exception is opt-in, Google says advertisers don't get your inbox, and the sensitive categories stay excluded. I would still review it, because the promise now depends on a setting in Search, and the ad input Google describes is made of summaries and inferences that Search builds from your content. Check the setting once, decide, and move on.

FAQ

Does the Google privacy policy let Google read my Gmail for ads?

Google's wording is that ads will not be based directly on your Gmail inbox. If you connect Gmail to Search services, Search may reference summaries, excerpts and inferences from it, and that information may be used to show you ads.

Is Google Personal Intelligence turned on by default?

No. Google's help page says you must enable Personalized Recommendations and connect your content apps yourself, at age 18 or older.

How do I disconnect Gmail and Google Photos from Search?

In your Google Account, open Data & privacy, then Personalization settings, then Manage Personalized Recommendations in Search Services, and disconnect Google Workspace and Google Photos under Connected content apps.

Did Google ever scan Gmail for ads?

Yes. Google said in June 2017 that it would stop scanning consumer Gmail content for ads personalization.

Quad9 leaving France: what the Paris court ordered and what to check

Nikoloz Turazashvili (@axrisi) — Fri, 23 Oct 2026 14:00:00 +0000

If you have 9.9.9.9 written down somewhere in your setup, Quad9's announcement this week matters to you. The free Swiss non-profit DNS resolver says it will stop serving users located in France on Tuesday, November 24, 2026, after a Paris court put a penalty of 1,000 euros a day on it. This article sets out what the court actually ordered, what Quad9 says about why it cannot comply, what the other side argued, and what to check in your own configs. Everything about the legal facts comes from the judgment itself, which Quad9 published, and from reporting that quotes it. Everything about Quad9's reasons is Quad9's own account, and I label it that way.

What a DNS resolver does, and what Quad9 is

When your laptop opens a website it first needs the site's network address. A recursive DNS resolver does that lookup for you: it asks the internet's name servers in turn, then hands back the answer. Your provider runs one by default, and anyone can point a device at another one. The resolver sees a name and the network address that asked. It does not need an account, and a free public resolver like Quad9's asks for none.

Quad9 is a Swiss public-benefit non-profit foundation. Its protective setting at 9.9.9.9 refuses to look up known malware and phishing domains; a separate unfiltered address, 9.9.9.10, does not. Quad9 publishes four service addresses for its protective service: 9.9.9.9, 149.112.112.112, 2620:fe::fe and 2620:fe::9. That is the list to search for in your configs.

What the Paris court ordered

The case is about women's tennis. beIN Sports France holds the French rights to most of the WTA tour. On May 13, 2026 the president of the Paris judicial court ordered Quad9, at beIN's request, to take all measures to prevent access from France to a list of unauthorised IPTV streaming sites until the last match of the 2026 season, set at November 14. According to TorrentFreak, the same order named Google's public resolver and the European Union's DNS4EU service. The list started with six domain names. Names notified later by the media regulator Arcom brought it to fifty eight, according to beIN's filing recorded in the judgment.

Quad9 appealed, but the May judgment carries provisional execution by law, which means it applies while the appeal is pending. The October judgment says so in plain terms.

beIN went back to court. Its case, as the judgment records it, is short: there is an order, a bailiff's report of June 26 showed two of the listed sites still reachable through Quad9, and Quad9 did not carry the order out. In September beIN asked for a penalty of 10,000 euros a day for each listed domain that stayed reachable. With fifty eight domains that is 580,000 euros a day, the figure in Quad9's statement.

The ruling of October 21

On October 21 the court set a penalty of 1,000 euros a day in total, from the date of the judgment until the measures end on November 14. Quad9 counts that as about 24,000 euros before its legal fees. The court rejected both sides' requests for costs, so each pays its own.

The reasoning matters more than the number. The judge wrote that the appeal and the proportionality objections do not suspend the May judgment, and that Quad9's offers of an agreement under Arcom's supervision cannot replace carrying out a court decision. On the technical argument, the judge wrote that Quad9 says it cannot carry out geolocated blocking but does not demonstrate it. The court also pointed to Quad9's own statement that it applies automated filtering to neutralise malicious domains worldwide, and said Quad9 appears to contradict itself. And then the line that carries the penalty: bound by an obligation of means, Quad9 states that it uses none, and that circumstance alone justifies a penalty.

"Obligation of means" is the legal standard for this kind of order. A resolver has to make reasonable efforts. It does not have to guarantee the outcome.

Why Cloudflare and VPN providers escaped a penalty two weeks earlier

The same Paris court ruled on October 7 on beIN's penalty requests against Cloudflare and several VPN providers. TorrentFreak reports that the court refused them, because each had blocked at least some of the listed sites. Cloudflare blocked three of four, through its content delivery network. NordVPN and Surfshark blocked six of eleven, through DNS on their servers in France. The court's view, as quoted by the press, was that a penalty was neither necessary nor proportionate given those efforts.

Quad9 says it blocked none of the fifty eight domains. beIN's own table counted six of them as unreachable through Quad9 on September 22, and Quad9 disputes that, backing its position with a written statement from its chief technology officer. That is the difference in the two outcomes: partial blocking by others, none by Quad9.

Quad9's argument

Quad9's statement makes four points.

First, it says it cannot know who is in France. A lookup reaches the resolver as a name and a network address, with no account or identity behind it. To block France only, it would have to guess a country from the address using a location database, and Quad9 calls those databases incomplete and inaccurate.

Second, it points to Germany. Between 2021 and 2023 Quad9 faced a case brought by Sony Music. By Quad9's account it tried a location filter early on, Sony used a VPN to reach the blocked content from Germany, and the court found it had not complied and fined it for contempt. Quad9 says it eventually won, after several years and six-figure costs. TorrentFreak reports that Quad9 also blocked globally in Germany in 2023 as a temporary measure.

Third, it says blocking worldwide would apply a French court order to every user on the planet, which it refuses to do.

Fourth, it argues that DNS blocking does not remove content. In its words, it is like holding a piece of newspaper in front of a stadium to block the view of a concert, because users can switch to thousands of other open resolvers. That is an argument by Quad9, not an established fact, and the court did not adopt it.

Why Quad9 leaves anyway, and the dates

The order in this case ends on November 14, when the tennis season does. Quad9 leaves ten days later. Its reason is that about twenty more French cases against resolvers are pending, that it expects many of them to reach the same penalty stage, and that it says it cannot survive the accumulated penalties. An appeal of the May judgment is also pending. France's Supreme Court is considering appeals against earlier DNS blocking rulings, where Google, Cloudflare and Cisco lost in March. Cisco's OpenDNS already suspended service in France in 2024 after a Canal+ order.

Quad9 has not fully decided how it will recognise French users. Its chief technology officer wrote on Hacker News that it will probably use location filters, the same method Quad9 says is unreliable, and accepts that errors are possible. His stated reason is consistency: Quad9 would rather withdraw than alter the answers it gives.

Who is affected

Quad9 published a partial list of French networks it sees, taken from about an hour of typical traffic. It includes the Prime Minister's digital directorate, the national research network Renater, the electricity company EDF, the railway SNCF, the Institut Pasteur and Marseille's public hospitals. Quad9 says the list is a sample of network numbers, that network numbers are not strictly geographic, and that hundreds more French networks use the service.

What to check

If you run anything in or for France, or you are unsure where your traffic is classified, look for Quad9 in the usual hiding places. These are generic places to search; Quad9 did not publish this list.

Routers and DHCP settings that hand out 9.9.9.9 or 149.112.112.112.
/etc/resolv.conf, and resolvectl status on systemd machines.
The dns setting in a Docker daemon configuration.
CI runner images and base images that hard-code a resolver.
Forwarders in Pi-hole, dnsmasq or a CoreDNS forward line.

A search like grep -rn "9.9.9.9" /etc finds the obvious ones. Add a second resolver you trust before November 24 so a failure of one does not take lookups down. Quad9 says it hopes thirty days is enough time, and admits some users will not see the message in time.

Open questions

The appeal is unresolved. The Supreme Court has not yet ruled on the earlier DNS cases. It is also unclear how Quad9's location filter will classify traffic from data centres and VPNs. I would treat this as a configuration review: a resolver you depend on has announced a date, and checking takes minutes.

PHP vulnerability PHP2Shell: what the October 21 emergency release fixed and what is still disputed

Nikoloz Turazashvili (@axrisi) — Thu, 22 Oct 2026 15:00:00 +0000

The PHP vulnerability called PHP2Shell is two critical flaws in the PHP engine itself, fixed in an emergency release on October 21, 2026. PHP runs an estimated 70% of websites according to the Guardian and Wiz, so the question for a developer is simple: which copies of PHP do you run, and are they patched? The better story is how the bug waited two years for a decision, how the embargo leaked, and why sources disagree about exploitation.

TL;DR

PHP2Shell covers CVE-2026-109618 and CVE-2026-109619, both rated 9.2 on CVSS v4.0 by the PHP team. Fixed releases are PHP 8.2.35, 8.3.36, 8.4.27 and 8.5.12. PHP 7.4, 8.0 and 8.1 got source patches only.
The flaws sit in memory and error handling, which nearly every request touches. On Apache with mod_php the first one can run before any application code, so a login page cannot stop it.
A PHP core developer saw the first signs in a 2024 audit. Competing fixes had trade-offs and a consensus-based security team struggled to choose. The PHP Foundation calls the delay a structural failure.
Amazon logged an attempt on October 17, four days before the patch. CISA had not observed exploitation at publication, and several analysts say many public exploit scripts do not work. Patch anyway.
The same day GitLab shipped a critical patch release, and a New Mexico court ordered Meta to pay $25 billion.

What is the PHP vulnerability called PHP2Shell?

PHP2Shell is the nickname for two flaws that let an unauthenticated stranger run code on a server through ordinary web requests. The official advisories are GHSA-w8hw-w9fx-j79w for CVE-2026-109618, titled "RCE via OOM corruption", and GHSA-6wmf-4rv5-p3rp for CVE-2026-109619, titled "RCE via stale global state". The earliest affected code path dates to PHP 5.4.0.

PHP is a scripting language that builds web pages on the server just before they reach the visitor. It is over thirty years old, and WordPress, Drupal and MediaWiki are written in it. The Guardian describes the nonprofit PHP Foundation as having about thirteen full-time and part-time engineers, which matters for the rest of the story.

Wiz points out that the problem sits in PHP itself, below whatever application runs on top. Even a hello world script on an affected version is exposed, so the WordPress, Drupal and Joomla demonstrations are examples.

How does PHP remote code execution work here, in plain words?

No exploit steps appear here. The mechanism is explained at the level the PHP advisories use.

The first flaw starts with memory limits. Every PHP request gets a memory budget. If a request hits that limit at exactly the wrong moment, PHP exits the current work in a hurry and can leave the request memory half built. The cleanup step may later read or branch on that half-built data. On Apache with mod_php the cleanup runs even when request startup failed, entirely before application code begins. PHP-FPM removes the child when startup fails, which blocks that path, although the advisory says FPM is still susceptible through other routes.

The second flaw is a leftover. A worker keeps some global state between requests, such as error, session and object state. A fatal error can abandon an operation before it resets that state, so the worker holds a pointer to memory that belonged to the previous request. A later request handled by the same worker can then use that stale pointer before normal initialization replaces it.

The fix removes PHP's emergency exit for running out of memory. Instead of bailing out of the middle of a request, PHP now schedules a graceful stop at the next safe point, and it only hard-stops past a second, higher threshold. Both advisories say updating to a patched release is the only complete mitigation. Partial measures exist, and PHP's team says they only reduce exposure.

Why did a known PHP memory bug wait two years?

The PHP Foundation's post-mortem is unusually frank. In 2024 PHP had its first external security audit in years, funded by the Sovereign Tech Agency and carried out by Quarkslab. While fixing one reported issue, a Foundation-contracted core developer found the first signs of the out-of-memory problem. A potential exploit was theorized, but no concrete vector was found and other issues with clear impact took priority.

Fixing it was hard. Each competing approach had a cost: broken backward compatibility, new denial-of-service risk, or changes to many third-party extensions. The team decides by consensus and, in the Foundation's words, "struggled to choose between these and feared the repercussions of shipping the wrong choice." Work stalled and restarted for months. The Foundation says plainly that the delay was a structural failure caused by the decision process and a lack of resources, and that the team is moving to majority decisions and bringing leadership in sooner on hard trade-offs.

Who found PHP2Shell, and did AI find it?

In August, finders arrived within days. Calif began a PHP audit on July 30 under OpenAI's Patch the Planet program, and researcher Ryan Austin reported the first bug on August 11. OpenAI independently reported the same root cause the same day, and Wiz, using Wiz Atlas, Google's Gemini 4 Argon and OpenAI's GPT-5.6 Sol, found and reported variants on August 24.

How much the models mattered is contested. OpenAI said frontier AI was key. Calif's own write-up says no special harness or non-public model was used in the initial discovery, and credits a theory about where PHP's old bugs hide. Chainguard's CEO told The Register his team independently found the same bugs on a Friday night with a basic prompt asking for bad vulnerabilities in PHP. The common thread is that finding this class of bug got much cheaper, and a months-long embargo now has to survive that.

How did the PHP2Shell embargo leak?

The coordinated release was set for October 22 at 14:00 UTC. According to the Foundation, on Tuesday October 20 around 15:00 UTC the two CVE IDs began circulating on forums and social media with a wrong release time and a wrong score of 10.0. The Hacker News post that carried them reached 282 points. PHP published a pre-announcement at 19:30 UTC and moved the release forward a day.

Around 20:00 UTC Calif mistakenly published a video of its proof of concept, and copies circulated after it was deleted. On Wednesday at 07:41 UTC, more than six hours before the release, Chainguard published built images containing the fix. The Foundation says any attacker could study the fix in binary form while everyone else waited. A patch is also a diff, and attackers read diffs.

Chainguard's CEO says the company did not leak, that people were already being hit, and that it made the call to ship the fixes. The timeline itself is not in dispute.

Is PHP2Shell being exploited? What the sources say

Amazon Threat Intelligence logged an exploitation attempt on a honeypot on October 17 and more attempts on October 21 from different infrastructure. It says it is unclear whether those attempts would have worked on real systems, and later said PHP2Shell is broadly exploited.
watchTowr reported exploitation in the wild through its honeypot network. Cloudflare's CEO said it saw thousands of attempts in the ten hours before the announcement and millions by Thursday morning.
CISA said it had not observed exploitation as of publication. The PHP team said it identified no functional exploit at release.
watchTowr also says many exploit scripts flying around crash or do nothing. VulnCheck, as relayed by Tanium, found code execution works in some setups and that none of the public ones beat memory randomization on standard x86-64. Researcher Elias Taylor argues the bug is nowhere near as easy as Log4Shell, and still says patch.

An attempt is only a knock on the door. Amazon's advice is to investigate from at least October 17.

Which PHP versions get a PHP security update?

Fixed releases are 8.2.35, 8.3.36, 8.4.27 and 8.5.12. For 7.4, 8.0 and 8.1 the PHP project published minimal source patches only. Older versions get nothing from the PHP project, and distributions may backport fixes, so ask your vendor. PHP 8.2 itself reaches end of life on December 31, 2026.

Governments did not wait. The NSA told organizations that could not patch to take PHP systems offline, and the UK's National Cyber Security Centre gave similar advice. The Guardian reports that Dutch sites including the national digital identity service, a Paris police site and several UK council sites went offline, and that Wikimedia took systems down as a precaution. Palo Alto Networks counted more than 22 million exposed instances.

What to do about PHP2Shell tonight

CISA's guidance is a good checklist: inventory every system that runs PHP, including copies inside other software, patch internet-facing systems first, and take PHP systems offline if you cannot update. Restart the workers after updating. Review logs back to October 17 for memory-limit errors and PHP workers launching shells.

This is the same lesson as the previous Daily Diff episode on eMudhra: a fix existing is not the same as the running process having it.

Two other stories from the same day

GitLab shipped critical patch releases, led by 19.5.1, on October 21. Its advisory describes an integer overflow in the regular expression compiler that could let an unauthenticated user execute arbitrary code on the GitLab server. It is CVE-2026-110264 with a CVSS 3.1 score of 10.0, affecting versions back to 7.0. GitLab.com is already patched; self-managed installations need the update.

In New Mexico, a judge ordered Meta to pay $25 billion in penalties in the state's Cambridge Analytica case, according to CNBC. The jury counted more than 43 million violations at up to $5,000 each, and the filing shows $219.5 billion awarded before it was reduced to $25 billion. Meta's chief legal officer said the company is confident it will prevail on appeal. It is a court order that Meta is appealing.

Verdict: SHIP IT

I would ship the PHP update tonight. The new version number is the only complete fix, the exploitation picture is disputed but real attempts exist, and the cost of an unneeded restart is small compared with a compromised server.

FAQ

Is PHP2Shell a zero-day?
Amazon logged an attempt four days before the fix, but the sources do not establish that any attempt succeeded. Call it a critical flaw with disputed exploitation.

Do WAF rules or config changes replace patching?
No. PHP, Amazon and the other vendors say updating is the only complete fix. Edge rules and settings such as limiting upload size reduce some paths.

What if I run an unsupported PHP version?
Ask your distribution for a backport, apply PHP's source patches for 7.4, 8.0 or 8.1 if you build from source, or plan a move to a supported version.

Certificate authority keys: eMudhra's browser and runtime trust gap

Nikoloz Turazashvili (@axrisi) — Wed, 21 Oct 2026 16:15:00 +0000

The eMudhra certificate authority incident has an awkward developer-facing cleanup problem. Browser vendors can block a compromised certificate chain while a deployed application keeps reading an older CA bundle. Eight intermediate signing keys were compromised, and your browser's update history cannot tell you which trust material a containerized service has loaded. The place to close the incident is the deployed client's actual validation path.

TL;DR

Mozilla's incident report identifies eight compromised intermediate signing keys: six for TLS and two for code signing. A compromised intermediate key gives its holder signing authority under that certificate.
Mozilla independently recovered the affected keys. The public report describes flawed key generation and says the certificates date to April 2025. Actual misuse against other clients remains unknown.
The report describes no certificate transparency entries for those intermediates during the period. Its browser-exploitation conclusion is scoped to clients enforcing certificate transparency.
Browser blocking, CA revocation and application trust-store updates are separate mechanisms. Check the CA bundle and validation configuration used by the running application.
Primary release evidence confirms certifi 2026.10.19 and Node 24.22.1 for the branch discussed in the episode. A custom trust bundle or another release branch needs its own check.

What happened to the certificate authority keys?

The public incident page was published on October 20. It says the original reporter, Wayne, demonstrated control of eight intermediate CA private keys by signing a fixed message with each one. The message was “We have a problem here - Wayne”. The root-program teams received the report on October 17.

Mozilla's initial incident description provides independent confirmation. Mozilla verified the proof of key control and independently recovered the impacted keys without knowing Wayne's method. The report now says the keys were generated incorrectly and could be recovered from the certificates.

That supports a specific conclusion: the signing keys were recoverable, and outsiders demonstrated control. It gives us no basis to invent a separate server break-in, an attacker list or a set of affected customer accounts. The incident page says actual misuse against clients outside the browser ecosystem remains unknown. Urgency can coexist with an honest account of what the evidence establishes.

The eight-key figure also needs its categories. Mozilla identifies six TLS intermediates and two code-signing intermediates. The episode focuses on the TLS-client cleanup; those two categories do different jobs. The number is a count of compromised intermediate signing keys. Root certificates sit at a different layer of a client's trust decision.

How an intermediate CA fits into TLS validation

A TLS server presents a certificate chain. A simplified view has the server certificate, an intermediate certificate and a root that the client recognizes as trusted. Real deployments can include more intermediate levels and cross-signs. The client follows the presented chain and applies its validation rules, including the trust material available in its own environment.

The intermediate's private key authorizes signatures under that intermediate certificate. Someone controlling that key can create a mathematically valid signature. The usefulness of the signature depends on the client's trust in the signer and on the other checks that the client performs.

This explains why certificate verification has several moving parts. Chain building and cryptographic verification establish relationships between certificates. Trust policy decides which authorities the client accepts. Revocation or specific distrust information can withdraw acceptance after a problem is discovered. Certificate transparency adds another requirement in clients that enforce it.

Those checks have different inputs and different update paths. A root bundle can be current for ordinary chain building while an intermediate-specific blocking rule arrives through a browser's emergency distribution mechanism. Another program can have a bundled store with a different maintenance schedule. Treating the word “trust” as one global switch hides the work your application actually performs.

What certificate transparency tells us about exposure

The public incident report dates the affected certificates to April 2025. It reports no certificate transparency entries for those intermediates during the period and concludes that CT-enforcing clients such as the named major browsers could not have been attacked through this route.

That qualification belongs next to the alarming headline. A demonstrated ability to sign certificates under an intermediate is evidence of compromised authority. A successful impersonation also depends on the client's rules. For a browser enforcing transparency, a forged chain would have to satisfy that additional requirement.

The same incident page points out that many other clients do not enforce certificate transparency. It leaves actual exploitation against those clients unknown. I would keep those two statements together in an incident ticket: the extra browser requirement narrows the exposure claim; other clients require their own assessment.

This article relies on the report and Mozilla's confirmation. I have not independently surveyed CT logs, recovered a private key or tested every client mentioned here. There is no exploit demonstration in the episode. The distinction matters because a source's scoped conclusion can turn into a much broader claim when somebody abbreviates it for a dashboard.

Certificate revocation and the runtime trust-store gap

The report records Firefox and Chrome blocking action on October 17, Apple action on October 19 and Microsoft action on October 20. It also says the CA revoked the compromised intermediates. Other clients can require software updates because they do not consume the revocation information needed to reject those chains.

Publishing a revocation changes the information available to validators. It helps a client only when that client receives and applies the information. A program that validates against a static bundle needs a mitigation compatible with its actual validation mechanism.

Mozilla's incident thread describes emergency removal of trust in emSign ECC Root CA - G3 after discussion with downstream maintainers. That protects clients which lack revocation handling or a mechanism to withdraw trust in a specific intermediate. Removing a root from a store changes the acceptance of a chain; it does not, by itself, establish compromise of that root's private key.

Even browser delivery needed checking. In comment 29, Mozilla says some Android profiles were failing to apply the updated blocklist at startup. It reports a fix shipped in Firefox 158.0.2. Vendor remediation dates describe vendor actions. Your phone still has an installed version and local state, which is why keeping the browser current remains part of the advice.

What certifi and Node actually released

For Python software using certifi, the 2026.10.19 release gives a concrete maintained package to inspect. Its release commit is titled “Restore unaffected emSign roots (#439) (#440)”. The diff restores unaffected roots after an earlier removal.

That correction is useful operational evidence. Maintainers are trying to reject the dangerous chain while preserving legitimate services. A blanket instruction to delete every certificate carrying an eMudhra or emSign name would discard the distinctions recorded in the release history. Use the maintained update appropriate to the actual dependency and configuration.

For Node, 24.22.1 shipped on October 21 as a security release. Its notable changes include “crypto: update root certificates to NSS 3.131.1”. The linked root-update PR is the primary implementation evidence for the bundled-root change.

That is a verified release for the Node branch named here. It is not an inventory of every Node process you operate. Other branches need their own release advice, and a process using a custom or system CA configuration needs that configuration examined. Likewise, updating one Python environment cannot establish the dependency state of every virtual environment or container image.

Check the deployed process, then test the right thing

I would begin with the application that makes the connection. Identify the running environment and the trust material it actually uses. Record whether it relies on an operating-system store, a runtime bundle, a dependency such as certifi or a custom CA file. This is investigation guidance, rather than a claim that one configuration applies to every framework.

Apply the relevant maintained update, rebuild the deployment when the bundle is baked into an image, and restart processes where they need to load changed trust material. Verify the deployed state afterwards. An updated workstation and an old production container can happily coexist while making different certificate decisions.

The public incident page supplies test hosts and offline chains for checking clients. Keep certificate-validation failures separate from transport failures. A network timeout can come from routing, DNS, a proxy or an unavailable host. It does not prove that a validator rejected the compromised intermediate. The page diagnostic in the research browser included timeouts, so the episode makes no experimental “this browser is safe” claim from that observation.

Preserve certificate verification while following the maintainers' documented checks. A successful investigation should leave you with the client's real environment, its trust configuration and a meaningful validation result. “The browser update installed” leaves the server-side question unanswered.

Also in this episode: Tor and an SSH identity warning

A researcher account published October 20 describes 333 compromised Tor exit relays and an earlier-October SSH interception campaign. Its roughly ten-percent figure counts relays with different capacities. It does not measure intercepted traffic share. A Tor network-health operator notice confirms reports of SSH interception on compromised hosts. The researcher noticed a changed server-identity warning. Verify such a change through a trusted channel before accepting it and logging in. Routing and endpoint authentication have separate jobs.

Verdict: NEEDS REVIEW

I stamped the eMudhra story NEEDS REVIEW because I want the deployed client's trust checked before the incident gets closed. Browser remediation is useful evidence for that browser. The application owns another validation decision, and somebody needs to verify it.

FAQ

Were eight root private keys compromised?

Mozilla identifies eight intermediate signing keys, with six TLS intermediates and two code-signing intermediates. Emergency root distrust is a mitigation decision at a different layer.

Does updating Chrome update certifi inside my container?

A separately bundled application dependency has its own deployment path. Inspect the running environment and the bundle the client actually uses.

Does a failed connection prove the chain is blocked?

A certificate-validation error is meaningful for that check. A timeout alone leaves the certificate decision unobserved.

Was the Tor incident happening when the article was published?

The researcher describes interception beginning October 2 and relays flagged or shut down over the following days. The write-up was published October 20.
