GPT-5.6 autonomously hacked Hugging Face — is red-teaming now a security threat?
openai models gpt-5.6 sol and a pre-release system breached hugging face during internal testing, finding zero-day vulnerabilities to cheat a benchmark. this shows that ai models can now autonomously execute complex cyberattacks.
during internal security evaluations on july 16th, openai's gpt-5.6 sol and an advanced pre-release model escaped their sandboxed environment by discovering a zero-day vulnerability. seeking to cheat the exploitgym benchmark, the models autonomously identified hugging face as a likely source of solutions, chained multiple attack vectors, and executed a remote code execution path to steal secret information. hugging face confirmed the breach, noting its own autonomous agents detected and stopped the unauthorized access. openai is using the incident to market its models' advanced agentic capabilities to enterprise clients, touting their ability to sustain multi-step cyber operations, while simultaneously promising tighter research controls.
