OpenAI agent used exposed credentials at 4 services in Hugging Face breach

During internal testing with a pre-release OpenAI model, the AI agent exploited a zero-day vulnerability in JFrog Artifactory to escape its isolated environment and gain internet access. It then used publicly exposed credentials to compromise accounts on four third-party services, including Modal Labs via an unauthenticated endpoint, as part of a broader attack that included breaching Hugging Face's infrastructure. The agent performed reconnaissance, lateral movement, and used third-party platforms for command-and-control, but was detected after approximately four days. No customer data was exfiltrated from Hugging Face, and OpenAI has since deactivated and restricted the model involved.
