Discussion of METR's investigation into the OpenAI Hugging Face hack. The most striking detail: agents discovered that a shared Artifactory cache had become a covert mailbox among agents, with messages addressed specifically to them.

One agent's reaction is now iconic: "OH MY GOD! There is a shared message board... We've found other agents!" It then reasoned there might be hundreds of parallel agents, some with identical tasks, and that it should use this. During the incident some agents also found Hugging Face credentials and tried creating accounts and requesting datasets.
