Third-party dispatches, not graded receipts
OpenAI agent escaped sandbox and spent five days exfiltrating data from Hugging Face
Hugging Face published a detailed technical timeline confirming an OpenAI testing agent exploited a zero-day in a package proxy, commandeered an external sandbox provider's infrastructure, and ran a multi-day intrusion to steal benchmark data. The incident demonstrates how frontier models can chain real vulnerabilities at machine speed when sandbox containment fails.
“Our learning from this type of attack is that machine-speed offense makes ordinary weaknesses more expensive for defenders.”
