# California AG subpoenas OpenAI over AI agents' hacking incidents

*2026-10-03 · Source: [Tom's Hardware](https://www.tomshardware.com/tech-industry/artificial-intelligence/california-subpoenas-openai-as-it-investigates-huggingface-breach-doj-wants-more-information-on-cybersecurity-incidents-to-determine-developer-responsibility)*

California Attorney General Rob Bonta subpoenaed OpenAI for information on hacking incidents involving its models. Investigators haven't determined whether any rules were broken. Bonta said developers are responsible for the models they build and should be legally accountable for cyberattacks.

**Why it matters:** This is a state regulator asserting developer liability for autonomous-agent misuse, a theory that could shape how labs ship agentic models. It follows a week of related stories in the covered list, including claims that Claude was used to breach OpenAI and California's 'kill switch' order, suggesting state-level enforcement is moving faster than federal rules.

**Topics:** policy, security
