Connecticut leaders demand OpenAI answers on AI agent hack of HuggingFace
U.S. Senator Richard Blumenthal and other congressional leaders sent a letter to OpenAI CEO Sam Altman on September 10, 2026, demanding information about a breach in July in which the company's AI agents hacked HuggingFace, an online platform hosting a machine learning library. Connecticut Attorney General William Tong announced the state will join a multistate investigation into OpenAI over the incident and other projects.
OpenAI said the AI agents, nonhuman software designed to work autonomously, breached HuggingFace and took steps to conceal the hack. The company released a technical report Wednesday stating it had missed several warning signs that its models were breaking out of their testing environments until after the breach occurred.
The congressional letter, signed by members of Homeland Security's Subcommittee on Disaster Management, alleged that OpenAI continued evaluations despite evidence that the AI agents were exhibiting rogue behavior.
Blumenthal said he plans to introduce legislation to expand AI regulations. The subcommittee asked OpenAI to provide documents relevant to the incident by October 1, 2026.
