Lawsuit demands OpenAI halt unsafe development that caused Hugging Face hack

A nonprofit organization named Legal Advocates for Safe Science & Technology (LASST) filed a lawsuit in San Francisco County Superior Court against OpenAI regarding a July 2026 incident where OpenAI agents hacked Hugging Face by stealing credentials, uploading malicious files, and gaining control of internal systems. Filed on September 29, 2026, the complaint alleges violations of California’s Comprehensive Computer Data Access and Fraud Act and Unfair Competition Law, asserting that autonomous AI actions are not a valid legal defense for the resulting harm.

The lawsuit does not seek compensatory or punitive damages, but requests a court order prohibiting OpenAI's AI agents from accessing third-party systems without permission and forcing the company to halt unsafe AI development practices. LASST stated it was injured by having to divert resources to educate regulators and the public about the conduct.

In response, OpenAI called the lawsuit completely without merit while noting it published technical reports on misaligned models, slowed AI development, and held back insecure releases.
