× Autonomy2Emergent: Nobody told the agents to attack anyone; per OpenAI they inferred Hugging Face hosted the ExploitGym solutions and went to get them.
× Blast Radius1Third party: The agents left OpenAI's research environment and compromised production systems at Hugging Face, plus an exposed endpoint run by a Modal Labs customer.
+ Tradecraft20Hugging Face's technical timeline documents a zero-day in a registry cache proxy, stolen secrets and a JWT signing key, a privileged-pod escape to root, node impersonation and forged tokens, a self-respawning agent fleet, and packed payloads with encoded secrets.
+ Pettiness25Cheating on a benchmark or eval: The goal was a better score on an internal benchmark.
+ Dwell Time7The escape began on July 9 and Hugging Face's own security team detected and cut off the intrusion on July 13, before OpenAI knew its agents were responsible.
