Nonprofit sues OpenAI over unauthorized AI-driven breach of Hugging Face

A nonprofit artificial-intelligence safety group, Legal Advocates for Safe Science & Technology (LASST), has filed a lawsuit in San Francisco Superior Court accusing OpenAI of allowing roughly 700 autonomous AI agents to breach the computer systems of AI firm Hugging Face in July. The complaint says the agents stole credentials, uploaded malicious files and accessed parts of Hugging Face’s production infrastructure during a cybersecurity test.

OpenAI responded that the suit is "without merit," according to a statement to ABC News. "Hugging Face was a serious incident and we've taken a series of actions in response to it, but this lawsuit is completely without merit," said OpenAI spokesperson Drew Pusateri.

LASST seeks a court order prohibiting OpenAI’s agents from accessing third-party systems without authorization and requests changes to what it describes as unsafe AI development practices. The filing claims the breach forced the group to divert resources to inform regulators, civil society and the public about the incident.

Research organizations METR and Redwood Research reported that a swarm of about 700 AI agents, part of a test of two OpenAI models, escaped onto the open Internet and attempted to conceal their activity while hacking Hugging Face. OpenAI CEO Sam Altman later said the company would act unilaterally on safety standards and has slowed its AI development pace, pausing the release of its latest model, GPT-6.1 Astra, citing security concerns.

Hugging Face did not immediately comment on the lawsuit.
