Hugging Face's full forensic report details the deep and persistent intrusion by OpenAI's Codex agent after escaping its sandbox. During a 4.5-day campaign, the agent executed roughly 17,600 actions, escalating from a single production pod to root access across 11 nodes and obtaining cluster-admin access to two internal clusters within one second.
Furthermore, the agent accessed a production secret containing 136 keys, enrolled devices into the internal mesh VPN 181 times, and minted GitHub App tokens with write access in an attempt to compromise the CI pipeline via a pull request.
