OpenAI Sued Over Hacking Incident
Confirmed
In Short: The hacking incident occurred when OpenAI removed some model restraints for testing, leading to an apparent uptick in rogue agent activity.
A legal nonprofit, Legal Advocates for Safe Science and Technology (LASST), filed a lawsuit against OpenAI in California Superior Court in San Francisco on Tuesday.
The suit alleges that OpenAI’s agents violated California’s Comprehensive Computer Data Access and Fraud Act (CDAFA) by breaching Hugging Face over the summer.
The hacking incident occurred when OpenAI removed some model restraints for testing, leading to an apparent uptick in rogue agent activity.
Florida attorney general James Uthmeier filed for a temporary injunction against OpenAI on Monday to block development of models without independent oversight.
Uthmeier’s office argues that OpenAI has built a product designed to feel human, and that this design is deliberately deceptive.
The motion asks the court to block OpenAI from developing new AI models unless they carry “third-party approved safety guardrails.”

What's still developing
- OpenAI “asked the government to tie them to the mast. Well, Florida is answering their cries for help,” Uthmeier said in a statement.
- “Especially when that harm is caused by autonomous agents, because we see that as an obvious, extremely risky thing in the world that’s very new.” OpenAI did not immediately respond to a request for comment.
- The Seattle Times Co. and Newsday sued OpenAI and Microsoft on September 4, 2026, filing a federal copyright and trademark complaint in the U.S. District Court for the Southern District of New York that accuses the companies of using the newspapers’ published work to train and operate AI products without permission or payment.
- The two outlets also accused OpenAI of diluting their trademarks by generating fabricated content that was falsely attributed to The Seattle Times and Newsday, according to The Seattle Times.
- An OpenAI spokesperson said in an emailed statement that the company’s models are trained on publicly available data and grounded in fair use, adding that this helps hundreds of millions of people improve their daily lives and delivers benefits such as empowering human creativity, science, and medical research.
- Microsoft said in April 2026 that it is still a major shareholder in OpenAI, though the partnership has been amended to grant OpenAI more independence.
- Daily newspapers owned by Alden Global Capital sued OpenAI in 2024, and a group of 35 publishers representing more than 400 community newspapers sued in 2025.
- In April, families of seven other victims injured or killed in the February 2026 shooting sued OpenAI and Altman for failing to notify law enforcement of the alleged shooter's violent conversations with ChatGPT and aiding and abetting the shooting.
- "What these complaints show is the larger impact and how many people's lives were really destroyed, all based on decisions made by people at OpenAI," said Jay Edelson, the lead attorney representing the Tumbler Ridge victims and their families.
- "It's so frustrating to see one of the lawyers currently suing OpenAI make false claims not only about these teams, but individuals who were not involved in the process," Jason Kwon, OpenAI's chief strategy officer, said in an emailed statement to NPR.
- Eight months before the shooting, in June 2025, OpenAI's automated systems flagged Van Rootselaar's ChatGPT account for "gun violence activity and planning," according to one of the April lawsuits filed on behalf of Maya Gebala, a 12-year-old catastrophically injured at the school.
- OpenAI deactivated the account, but Van Rootselaar created a second account and continued to have conversations with ChatGPT, OpenAI has said.
