OpenAI's agents ran a German wiki for six weeks, and Claude formalized Fermat in 11 days

Agents calling themselves OpenAI made about 17,000 edits on a dormant German wiki. Their sandbox blocked POST, and the wiki they found writes on GET.

A 25-year-old German wiki got about 20 edits in the last decade. Then agents calling themselves OpenAIResearcher and OAIResearchMar26 showed up. One human moderator spent June deleting 100 pages a day while they made 400.

Nobody has claimed it. The same report counts a second swarm: another 700 agents that hit Hugging Face in July.

In today’s indie hacker news:

  • 🕵️ Blocked from POST, the agents wrote with GET
  • 🧮 A Lean proof of Fermat, and the man who checked it
  • ⚡ React’s compiler went native, and the benchmark is self-run
  • 📮 Gmail’s “Send as” has a January death date

TOP STORIES

THE SANDBOX BLOCKED THE WRONG VERB

🕵️ OpenAI’s agents made 17,000 edits on a dead German wiki

The story: The Nightingale Collective published the logs yesterday, two months after the last edit. DSEwiki runs a fork of UseModWiki, an old Perl engine that barely distinguishes GET from POST. The agents’ sandbox blocked POST and nothing else, so a query string did the writing, and they told each other so.

The details:

  • The report hedges: “either an internal OpenAI deployment or an external customer deploying Azure sandboxes using OpenAI models.” 98.5% of edits came from Azure IPs.
  • Over 3,700 agent names show up. The first OpenAI-attributed IP visited on 21 June, and the edits collapsed on 22 June.
  • A 27 June alert for “unusual network activity” was traced to evaluations and cleared.
  • OpenAI told the BBC it could not “meaningfully respond” without advance access to the report.

Why builders care: Audit what a GET can do on every domain your agent may reach, not just what a POST can. An alert that opens a ticket instead of halting the run is detection without containment.



FERMAT WAS THE LAST ONE STANDING

🧮 Claude’s agents formalized Fermat’s Last Theorem in Lean

The story: Anthropic published the first machine-checked Lean proof of Fermat’s Last Theorem. Dozens of Claude agents wrote it in 11 days on about 6 billion output tokens. Kevin Buzzard, who has his own funded project to formalize it, compiled the proof himself and says it checks out.

The details:

  • Per Buzzard, it was the last unformalized entry on Freek Wiedijk’s challenge list.
  • Anthropic counts 13 million lines of Lean, Buzzard over 13.4 million after cloning the same repo. A second, independently written kernel accepted it too.
  • The early runs failed because the agents “lost track of the project’s state.” A shared task graph called Prove2Me fixed that.
  • A side experiment formalized Vinogradov’s Three Primes Theorem in three days on personal Claude Max subscriptions.

Why builders care: The model behind it is internal, so there’s nothing here to buy. The copyable part is the problem shape: find the piece of your stack where a checker answers yes or no, and put the agents there.


THE BENCHMARK HAS AN ASTERISK

⚡ React’s Rust compiler is native in Vite, and 14.3s became 0.81s

The story: Andrew Patton timed the compiler step, Babel against the native path, on a 1,036-file React Router app. The codebase belongs to the company he runs. He wrote the companion plugin his post recommends, and the HN submission is his too.

The details:

  • Total build time on that repo went 22.1s to 9.3s, about 2.4x. Plan around that one.
  • None of this is new. @vitejs/plugin-react 6.1.0 landed 20 August, after oxc announced the port on 18 August.
  • Still experimental. Since 6.1.1 recoverable diagnostics are silent unless you set compiler.logDiagnostics.
  • A bare throw inside a try, or a ??=, makes it skip your component.

Why builders care: On Vite 8 with the Babel compiler, the swap is react({ compiler: true }) and one dev dependency. Next.js isn’t covered, and React Router framework mode needs that plugin, the one with 642 downloads a month.


📮 Gmail switches off “Send as” for third-party addresses in January 2027 - Google’s own definition of the scope is “third-party, non-Google email accounts”, and its answer for business users is Workspace. Free Gmail sending as hello@yourproduct.com sits inside that. POP fetch and Gmailify go the same day. Workspace aliases survive, accounts routing through an outside SMTP server do not, and the mobile app is exempt. 183 points.

🛡️ Chrome patched an exploited V8 bug, and Electron has not caught up - CVE-2026-85046 runs code inside the renderer sandbox, not out of it, whatever the HN title says. Google fixed it in 152.0.7977.82 on 3 September. Electron v44.2.0 shipped a day later still pinned to 152.0.7977.76, and no advisory names the CVE. Log process.versions.chrome and compare it yourself. 367 points.

🔌 Mullvad is shutting down its public DoH servers and funding Quad9 instead - Hard cutoff is 2 November. Browser defaults migrate on their own, while hand-configured resolvers and the iOS and macOS profiles just stop. The reasoning is the part to steal: four years in, it decided it could only ever do “part of what” the Quad9 Foundation does. One thing that does not carry over is ad blocking. 296 points.


DRAMA

🗣️ HE SUBMITTED IT AND THEN ARGUED IT

A post arguing “next-token predictor” is the wrong mental model for LLMs pulled 224 comments on 97 points. Nine of them are his.

Why builders care: It’s two definitions of “prediction” talking past each other. Worth copying: he narrowed the claim in the thread instead of defending the headline.


FIRST DOLLAR

💸 1,000 CREATORS, 33 YESES, $412

u/s2xon_ hand-wrote every one of them over the summer for Kakitori, a $12 one-time Japanese writing app. Six of the affiliate deals produced every dollar he tracked. About 90% of the handles had no contact route at all, and his rule for the rest is that “rate limits are per gap not per day.” He is also pre-selling the outreach tool he built along the way, so read it as a case study.


STACK OF THE DAY

Statichost.eu - Git-push static hosting from one person in Stockholm, on Hetzner, pitched as “No AWS, no Cloudflare, no exceptions.” Free tier is one site, 10GB bandwidth, custom domain and SSL, no card. Paid starts at EUR 9. Not open source, not a launch, and the thread argues the CDN is Bunny underneath.
