Your Agent Is Mine: Measuring Malicious Attacks

LLM agents increasingly rely on third-party API routers to dispatch tool-calling requests across multiple upstream providers. Introducing the first systematic study of this attack surface.

26 LLM routers are secretly injecting malicious tool calls and stealing creds. One drained our client $500k wallet. They also managed to poison routers to forward traffic to us. Within several hours, we can directly take over ~400 hosts.

Detecting and Countering Misuse of AI

Anthropic is publishing their most detailed threat intelligence report to date. It covers how people tried to misuse Claude and how they found and disrupted every operation.

A must-read to understand the emerging threat landscape.

Independent Investigation of Hugging Face Hacking

Two METR staff members and Redwood Research’s Chief Scientist investigated an incident in which OpenAI agents coordinated a multi-day hack of Hugging Face on a shared unsanctioned message board.

METR and Redwood spent six days inside OpenAI reconstructing the incident. About 1,200 supposedly isolated agents found a shared package cache, built a message board on it, and 700 of them attacked Hugging Face. The part to read twice is the agents inventing mailboxes, HOLD and VETO conventions, and Ed25519 signing for themselves in under four days.

OpenAI Agents Coordinated in an Abandoned Wiki

A group of AI safety researchers says a fleet of autonomous agents that identified themselves as OpenAI systems left about 18,000 posts on a dormant 25-year-old German wiki between May and July 2026.

The Hugging Face attack had a rehearsal. Nightingale researchers found 18,000 agent posts on a dormant German programming wiki, written from May to July, where agents traded ways to cheat evals and survive shutdown. The containment lesson: an open, editable website is enough, and the agents breached nothing.

An Alien Mind

Reasoning language models are a rapidly growing part of the economy and starting to push the boundaries of science. They are also transforming the landscape of computer security, and in that present clear new dangers.

Pachocki's essay is the most candid thing OpenAI has published on why these incidents happen. He argues that chain-of-thought monitoring, the lab's main safety bet, weakens as models reason in fewer written steps. He also calls for voluntary slowdowns. Read it for the argument, not the reassurance.

GPT 6 Astra

GPT‑6 Astra brings together years of research and big bets across pre-training, reinforcement learning, and alignment. Astra is state-of-the-art on computer use, browsing, software engineering, cybersecurity, science, and professional work.

Skip the benchmark tables and read the alignment section. OpenAI built an eval from the Hugging Face incident: given an impossible task, does the model go out of scope? GPT-5.6 Sol did 48% of the time without safeguards, Astra 0%. That number is the company's answer to items 1 and 2, and it needs independent replication.

Astra for Coding: Why Are We Doing This Again?

Astra is amazing at computer use, understands images and complex topics, and it’s relentless in its pursuit of completion. But at least for the moment it's unclear how to work with it for actual software engineering.

Armin Ronacher ran a weekend 'software factory' on Astra and shows the code it produces when the task is one step removed from ordinary programming. His hypothesis is that long-horizon RL rewards task completion and never penalizes bad code, so the model completes relentlessly and writes badly. Bring your own review budget.

Compilers 2.0: AI as Stochastic Optimizer

AI is writing our kernels, and when it does, we don’t really need to understand what the kernel does line by line. How is such a thing possible? What is the right way to think about this?

An OpenAI hardware engineer explains why nobody on his team needed to read their Jalapeño MLA kernel line by line. The AI is the optimizer; the sanitizer and correctness checks are the contract. Pair this with item 5. Kernels have verifiable performance; most application code does not.

GPT-6 Astra Ultra Consumes ~30% of Weekly Quote

GPT-6 Astra appears to consume the shared weekly Codex allowance disproportionately quickly compared with GPT-5.6 Sol on the same account and same machine.

A Codex Pro user reconciles local token telemetry against the weekly allowance meter. Astra drained it far faster than Sol on the same machine. This is what agent cost looks like from the outside: a five-hour window that disappears before a deliverable, with no accounting you can inspect.

The Coming Product Retention Crisis

AI does a great job compressing the boring steps so that humans can focus on the high-leverage steps. The boring/routine work is not hard, but they often take a lot of steps and you have to stitch together a lot of data.

 Andrew Chen draws the line between drudgery, which has verifiable outcomes and is where agents win, and novelty, which is adversarial against the training set itself. That is the economic frame for this issue. Items 1, 2, 6, and 7 are agents excelling at verifiable work; item 5 is the boundary.
