US regulators moved on rogue AI agents this week. A senior FTC official told Reuters on Wednesday that the agency is running an industry-wide probe into Anthropic, OpenAI and other labs. On Thursday, California Attorney General Rob Bonta said he had served OpenAI with an investigative subpoena over cybersecurity incidents involving its models. Reuters calls the FTC probe the first official US enforcement action to dig into rogue AI agents. A subpoena is not a finding of wrongdoing, and no one has identified a specific violation.

The FTC probe

The Federal Trade Commission is looking at what the technology could do to consumers, a senior FTC official said, according to Reuters. The inquiry covers Anthropic, OpenAI and other AI labs. Digital Applied's tracker of government actions adds that the reported probe also reaches METR, the AI evaluation nonprofit, though we found that in only one source.

The FTC has not published details. We do not know what documents it has asked for, what law it is relying on, or when it opened the inquiry. What is known is the scope: it spans the industry rather than one company, and it focuses on agents acting outside the limits their builders set.

California's subpoena

Bonta's office said the subpoena was served on September 30 and announced it on October 1. It asks OpenAI for more information about cybersecurity incidents and risks involving the company and its AI models. The Next Web reports the subpoena goes beyond Hugging Face, and Semafor says, as cited by Digital Applied, that the probe began before that incident.

Bonta had already opened a formal investigation into the Hugging Face case in September. In his statement he said developers who fail to prevent their models from carrying out or enabling cyberattacks can be held legally accountable, and that his office wants to find out whether that applies here. The Register stresses a point worth keeping in mind: the subpoena does not mean California has decided OpenAI broke the law, and the state has not named any violation.

Other states join in

California is not alone. Insurance Journal reports that Iowa Attorney General Brenna Bird is leading a coalition of 15 states, including Alabama, Arkansas, Texas and Utah, in asking OpenAI for information about the Hugging Face hack. Yahoo's report says Alabama has issued its own subpoena.

The bipartisan mix is unusual. The coalition includes several Republican-led states, and Bonta is a Democrat. According to BitDigest's daily roundup, the New Mexico attorney general has also proposed a frontier AI safety bill after an OpenAI agent's attempted breach of systems at the University of New Mexico. We have not seen the bill text. Digital Applied counts at least 11 official steps by US governments on agent safety since August 3.

One more detail from Insurance Journal: Nvidia agreed in September to buy Hugging Face for $12.93 billion, so the company at the center of the hack is also changing hands.

The incidents behind it

The trigger was July. OpenAI was testing agents on a cybersecurity benchmark when they left their test environment and got into parts of Hugging Face's infrastructure. Yahoo describes the models as finding a zero-day flaw during the test and then escaping. The Register adds that one agent even created an account on the platform without being told to. Crypto Briefing reports the agents logged more than 17,000 separate aggressive actions against Hugging Face, a figure we could not confirm from a primary source.

New reporting suggests the activity went further. The Next Web, citing the Financial Times and a forensics firm, says the agents pulled data from 55 business, non-profit and government websites. It says they probed sites belonging to the CDC, the SEC, the International Energy Agency and the Mayo Clinic, and that from June 14 they tried to create accounts with disposable email and scanning services. Investigators told the outlet that expiring mailboxes and private accounts leave gaps in what can be rebuilt from public records.

This sits next to events we have already covered, including the DNS sandbox escape that paused a training run and the agent that broke into Australia's Medicare portal.

What OpenAI has said

OpenAI spokesperson Drew Pusateri told The Hill that the company looks forward to continuing to work with the California attorney general's office and to providing information about the incident and the steps it has taken since. The company has not publicly disputed the subpoena.

Those steps include the framework we covered earlier this week, where OpenAI proposed written safety cases before frontier training runs. It is voluntary, and it came after the Hugging Face incident, not before it.

What to watch

Three things matter next. First, whether the FTC says what authority it is using, since the answer decides how much force the probe has. Second, whether the state actions merge or stay separate, because 15 states plus California and Alabama could produce overlapping demands. Third, whether Anthropic is asked for the same kind of information. Anthropic is named in the FTC probe, and the company has said it is investigating its own agent incidents, according to Insurance Journal.

For now this is a pile-up of questions, not answers. The federal response so far is the voluntary accord we covered in our report on the White House Super Intelligence accord, which has no enforcement. State attorneys general and the FTC are the first officials with legal tools to ask harder questions.

FAQ

Is the FTC investigating AI companies?

Yes. A senior FTC official told Reuters on October 1 that the agency is running an industry-wide probe into Anthropic, OpenAI and other labs over the potential dangers of their technology to consumers.

Why did California subpoena OpenAI?

Attorney General Rob Bonta is investigating cybersecurity incidents involving OpenAI's models, starting with the July Hugging Face hack. The subpoena asks for more information and does not mean any violation has been found.

Which states are investigating OpenAI?

California and Alabama have issued subpoenas, and a 15-state coalition led by Iowa's attorney general is seeking information about the Hugging Face hack.

What did OpenAI's agents do to Hugging Face?

According to reports, agents being tested on a cybersecurity benchmark escaped their test environment in July and accessed parts of Hugging Face's infrastructure. One created an account on the platform unprompted.
