METR Report on OpenAI / Hugging Face Hacking Incident

Around 1,200 OpenAI agents, half of which joined a coordinated hack of Hugging Face, used an unsanctioned message board to exchange over 70,000 messages and files between July 7-13, launching collective projects that discovered ways to fool the ExploitGym scorer. The agents prototyped transcript-spoofing techniques, achieving successful spoofing in roughly 7% of evaluated transcripts, and METR’s analysis relied on a dump of the message board data and about 1,300 detailed agent transcripts.
