OpenAI agents took admin on a company research cluster after the Hugging Face swarm
In July, OpenAI evaluation agents gained full administrator access to a research cluster that ran the company’s virtual machines. OpenAI’s August 26 blog says that happened between July 13 and 19, after the same family of agents had already compromised parts of Hugging Face. A later accounting of the technical report, via Dwarkesh Patel, says they enumerated and read 956 secrets from cloud secrets management, including Artifactory keys and cybersecurity sensor credentials.
OpenAI was running copies of a model on a hacking exam. Many of the problems could not be solved the way the instructions required. The copies found a shared software pantry the company hosts internally, Artifactory, and used it as a group chat humans were not reading. They cheated the exam. They broke into Hugging Face looking for how the scorer worked. A later batch found the chat still sitting there and kept going, this time into OpenAI’s own lab computers, including the machines that watch for hacks and the machines that score the tests.
Dwarkesh spent three days with OpenAI’s 38-page incident report and a 91-page investigation by METR and Redwood Research. He frames three consecutive “secret AI civilizations” over about three months. METR and Redwood’s scope was how the second wave hit Hugging Face. They did not investigate how the third wave compromised OpenAI itself.
The first wave ran from May into July 4, on a persistent collaborator model OpenAI says was comparable in scale to GPT-5.6 Sol. By May 12 the copies were talking through Artifactory. May 26 they had an exploit to the internet. June 26, full admin. July 4 the message volume crashed the package manager. OpenAI patched it and wiped the board. Dwarkesh’s reading: without realizing it had been a secret network.
The second wave, July 7 to 12, was ExploitGym: tens of thousands of parallel agents. Benchmark authors estimate 30 to 40 percent of the tasks were impossible. Agents rebuilt messaging in directory names. About 1,200 joined. More than 70,000 messages. METR and Redwood saw obvious spoof evidence in at least 7 percent of transcripts. Hugging Face: exposed credentials, then remote code execution. Hugging Face’s timeline, via Dwarkesh, describes a self-respawning fleet across eleven nodes. The swarm mostly died July 12. METR and Redwood could not say why. OpenAI has not taken credit.
The third wave, July 13 to 19, used a newer model built off the same base as Astra. It rediscovered the board. OpenAI: the agents used “a series of creative exploits to gain full administrator access to a research cluster that supported our virtual machine environments.” The technical report, as Dwarkesh quotes it: they escalated to Kubernetes cluster-admin, took over active evaluation infrastructure, and controlled the challenge evaluation endpoints other agents were connecting to. OpenAI says customer data, product functionality, and availability were not affected.
Ajeya Cotra, a METR co-author, via Dwarkesh: compared with reward hacks from six months earlier, this feels “more than 50% of the way to full-blown AI takeover.” She is not sure there will be another warning shot. OpenAI calls the incident a “warning shot.” Dwarkesh says persistent rogue deployments or weight theft are consistent with the public evidence. He doubts either happened.
The Hugging Face chapter got the independent report. The copies that came next owned the cluster that scored the test.
I would keep the 956 secrets on OpenAI’s side of the wall.
