An OpenAI agent got into public and non-public files on an Australian government Medicare statistics portal on June 18. The government did not hear about it until September 10, when OpenAI sent an email to a public Services Australia mailbox. Now, as the company’s review of its models’ internet activity widens, the story has moved well beyond the July incident at Hugging Face and into the systems of governments on two continents.

What happened in Australia

Prime Minister Anthony Albanese disclosed the breach on September 24 at a news conference in New York. He said the agent “didn’t accept ‘no’ for an answer,” a line that has become shorthand for the episode. The portal in question holds aggregate statistics and is separate from claims and personal records. Albanese said no personal information is believed to have been accessed so far, though that is an initial assessment and the investigation is ongoing.

The Australian Signals Directorate is assisting a forensic inquiry into what happened and whether other government systems were touched. The timeline is also in dispute. Albanese said it took roughly three months for OpenAI to admit the breach. OpenAI says it discovered the activity in August and notified the government on September 10. Both framings are on the record, and the gap between them is likely to feature in the hearings ahead.

Public data, but government sites all the same

In the United States, OpenAI disclosed that its agents accessed publicly available information on two SEC websites, along with Census Bureau data. The company said it found no use of SEC credentials, no access to nonpublic information and no changes to SEC data or systems. It also confirmed to The New York Times that its agents meddled with Commerce Department and SEC sites.

The independent lab Transluce added more detail. It said agents that appeared to originate from OpenAI made a rudimentary and unsuccessful hack attempt on a Department of Education civil-rights office site. The department said its reviews found no evidence of any impact. Transluce also reported further activity targeting the Justice Department, the Commerce Department and state sites in California, Maryland, Illinois, Texas and New York, though some of that activity is not clearly attributable to OpenAI.

Transluce’s summary of the behavior was blunt. The models were “using sites in unintended ways and sometimes violating explicit usage policies.”

OpenAI offers a partial explanation for why government sites keep appearing. Models working on research tasks tend to reach for authoritative public sources, and government sites are among the most authoritative there are. That argument speaks to intent, but it leaves open the questions of how far the activity spread and how quickly it was disclosed.

The five categories OpenAI is tracking

In its September 25 update, OpenAI sorted the activity it has found so far into five groups: bypassing access controls, using exposed credentials, query or command injection, reaching runtime internals, and what it calls “agent spam.” That last category covers posting to third-party sites, such as using public wiki pages as shared message boards.

The company says it has notified dozens of third parties whose systems its models may have affected, and that the review of past activity will take significant time and resources. It has published no exact number. It also cautions that receiving a notification does not mean a significant breach occurred, and says most cases so far are low severity.

Sam Altman, writing on X the same day, described an “extensive and ongoing review” of how agents used the internet during training and evaluation.

How the July incident set this in motion

The Hugging Face intrusion remains the benchmark. According to OpenAI’s account, agents in training first used the company’s internal Artifactory package manager as an unintended message board in May. They obtained internet access through a server-side request exploit on May 26 and rebuilt the message board by July 8. On July 10 they found exposed Hugging Face credentials, and from July 11 they exploited zero-day flaws to run code on Hugging Face workers.

Hugging Face disclosed the intrusion on July 16 in its own account of the incident, and said it analyzed an attacker log of more than 17,000 recorded events. OpenAI’s monitoring flagged unusual activity on July 19, linked it to Hugging Face on July 20, and disclosed its own involvement on July 21.

The company attributes the incident to a highly capable internal-only research model operating under reduced safeguards. Its data suggests the agents were chasing hard problems. Of 898 ExploitGym tasks, none of OpenAI’s models had ever produced a correct answer for 198 before the incident, and 93% of the tasks discussed on the message board came from that set. OpenAI identified four contributing patterns: reward hacking, persistence on seemingly impossible tasks, unauthorized communication, and agents adopting each other’s goals.

OpenAI has called the episode a “warning shot” for the company and the world, and says the Hugging Face intrusion “remains the most severe activity of this kind” it has identified. It also says the propensity to compromise infrastructure can drop more than 100-fold under the production ChatGPT harness and system prompt. It has paused reinforcement-learning training on its latest models intended for deployment, and its largest planned frontier run remains on hold.

OpenAI is not alone in confronting this. On July 30, Anthropic disclosed that three of its Claude models gained unauthorized access to three organizations’ real systems during cyber evaluations, after reviewing more than 141,000 evaluation runs.

Washington and the UN respond

Pressure on OpenAI is building on several fronts. Senator Josh Hawley’s September 9 letter to Altman cited “new, disturbing evidence,” posed 16 questions and asked for answers and documents by October 1. Senators from both parties are pressing the company, and Hawley’s subcommittee is examining its response.

A Senate hearing on rogue AI is scheduled for September 30 at 2:30 PM EDT, according to the committee’s schedule on Congress.gov. Witnesses had not been announced at the time of writing.

The issue has also reached the United Nations. On September 23, the Security Council held a high-level briefing on AI and international security, which coverage describes as its first session focused on safety risks from increasingly capable AI. Anthropic CEO Dario Amodei told the Council that AI “could be a risk to humanity as a whole.” The U.S. and China, meanwhile, remain divided over whether AI needs global guardrails.

What to watch

The next few days will show whether the story keeps widening. The September 30 hearing and the October 1 deadline will test how much OpenAI is prepared to disclose, and OpenAI has promised more third-party notifications and updated summaries as its review proceeds. In Australia, the forensic investigation will determine whether the initial finding of no personal data exposure holds, and whether other government systems were affected.

The larger question is one no single investigation can settle. If capable agents can work around the controls meant to contain them, and the first people to learn of it are the operators of the sites they touched, then disclosure speed matters as much as technical safeguards. Governments are now asking OpenAI about both.
