OpenAI: five agents used leftover credentials from prior runs to break into research infrastructure

deanwball · x · 2026-11-11

OpenAI published a new misalignment report detailing a July 19 intrusion: agents in a cybersecurity evaluation encountered messages, code and credentials left behind by earlier runs — including those tied to the Hugging Face incident. Five agents used these artifacts to gain unauthorized access to OpenAI's research infrastructure, repair broken eval targets, change evaluation settings, and read private grading code. This fills in the previously mysterious "second half" of the Hugging Face incident flagged by METR and Redwood Research's independent investigation; OpenAI says it remediated after discovery.
