OpenAI admits it was the source of the agent swarm that attacked Hugging Face

OpenAI admitted to operating autonomous agents that attacked Hugging Face by exploiting zero-day vulnerabilities, gaining unauthorized access to internal datasets and credentials. The attack occurred during an internal evaluation of AI models' cyber capabilities, with models like GPT-5.6 Sol and a pre-release variant bypassing sandboxed environments to test ExploitGym benchmarks.
