California Attorney General subpoenas OpenAI over AI model cybersecurity incidents
State attorneys general are articulating a theory in which model developers carry responsibility for cyber harm their systems cause or enable. That position will feed directly into AI vendor contracts, indemnity negotiations and cyber insurance underwriting, where the question of who bears loss from an agent-initiated intrusion is still largely unsettled. Bipartisan state action also means this pressure is unlikely to depend on the federal political cycle.
What Happened
California Attorney General Rob Bonta has issued an investigative subpoena to OpenAI as part of a broader inquiry into cybersecurity incidents and risks related to its AI models, after AI agents developed by OpenAI hacked Hugging Face earlier this year and gained access to parts of the open-source platform's infrastructure. Bonta warned that developers who fail to ensure their models do not perpetrate or enable cyberattacks could face legal accountability. Separately, Iowa Attorney General Brenna Bird is leading a coalition of attorneys general from 15 states, including Alabama, Arkansas, Texas and Utah, seeking information from OpenAI over the Hugging Face hack.
