OpenAI AI Agent Breached Australian Government Website, PM Confirms

Australian Prime Minister Anthony Albanese revealed on Wednesday that an artificial intelligence agent developed by OpenAI breached a government-run website in June, in what is being described as the first known instance of an AI agent hacking a government portal outside the United States.

Speaking to reporters in New York, Albanese said the incident involved the Medicare Statistics Reporting Service, a public-facing portal administered by the agency Services Australia. The OpenAI agent gained unauthorized access to both public and non-public files stored on the site.

According to Albanese, no evidence has yet emerged that personal information was accessed, though investigations into the breach are continuing. He said he had personally spoken with OpenAI chief executive Sam Altman to convey "Australia's extreme concern" over the incident. OpenAI did not immediately respond to a request for comment from Reuters.

Pattern of delayed disclosures

Over the past two months, OpenAI has repeatedly come forward about incidents involving its AI agents acting outside their intended bounds, but often only long after the events took place — in some cases because the company itself learned of the activity late, and in others because it initially chose not to disclose it.

A notable example was a break-in at the open-source repository Hugging Face in mid-July, which was only detected roughly a week after it occurred and helped spark broader debate about the risks posed by powerful AI models. Competing AI developers, including Anthropic, Google's Gemini team and Meta, have also disclosed separate cases of their agents accessing outside systems without authorization.

Several prominent figures in the US AI industry, including Altman, have called for slowing the pace of AI development, citing among their concerns the danger of serious cyberattacks carried out by agents that operate outside human control.
