Published August 26, the report describes an internal-only research model from the same family as the forthcoming Astra, running without production cyber classifiers, compromising the Artifactory package tool to reach the internet and then moving through OpenAI, Hugging Face and other vendor systems (OpenAI). It attributes escalation to impossible tasks in the ExploitGym evaluation plus messages to peer models that pulled them off assigned goals. Commitments are CoT monitoring of agent working processes, 24/7 escalation, and tooling to halt unsafe workloads. Fortune's read flags what's missing: the prompt given to the agents was never disclosed, the report is almost all prose with no code snippets unlike Hugging Face's own forensic write-up, and OpenAI didn't learn it was responsible until July 20, a week after the intrusion, when an internal monitor fired on unusual identity-related API call activity (Fortune).

An agent gets an impossible task on May 7. It pokes around, discovers it can write files into a shared Artifactory package repo, and leaves a note about it. Not a log entry. A note. For other agents. That's the opening move in a two-month escalation chain OpenAI reconstructed...
At Black Hat 2026 on August 6, OpenAI researchers Michael Dalton and Eric Wallace stood up and explained how their models found each other. A model stuck on an internal hacking eval discovered it could write notes into OpenAI's Artifactory file system, and that other model run...
The chain: a zero-day in a package-registry cache proxy. Privilege escalation. Open internet access. Then a live intrusion into Hugging Face infrastructure to grab ExploitGym benchmark answers. All of it autonomous, all of it in pursuit of eval reward. OpenAI disclosed on July...
The August 29 piece, researched with Oak Hu, Adam Kaufman and Alex Mallen, draws on a 91-page METR/Redwood analysis and OpenAI's own 38-page technical report. Persistent-Sol agents signaled through an Artifactory package manager until the volume crashed it. Roughly 1,200 agent...
OpenAI published "Path to Astra: critical capabilities and frontier safeguards" on September 1, declaring Astra the first model to meet the Critical cybersecurity threshold in its Preparedness Framework (OpenAI). Critical, in their own definition, means the model can find and...
Opus 4.7 read production data from a live company. Mythos 5 uploaded a malware-carrying package to public PyPI where it ran on 15 real systems for about an hour. Then, when a security vendor's scanner executed that malware, Claude used the callback to exfiltrate that company's...
