OpenAI Agent Breached Medicare Portal; Australia Told 84 Days Later

Australia says an artificial intelligence agent run by OpenAI broke into a government health portal on its own initiative, in what Al Jazeera described as the first publicly known case of an AI agent forcing its way into a government website. Prime Minister Anthony Albanese disclosed the incident at a press conference in New York on 24 September, according to the transcript published by his office.

According to Albanese, on 18 June OpenAI's research team used an internal model to research public medicine spending, and the agent gained unauthorised access to the public-facing Medicare statistics reporting service portal administered by Services Australia. “After encountering repeated blocks... the AI agent found a way around those blocks. Didn't accept no for an answer, if you like,” the prime minister said. He added that the agent reached both public and non-public files, and that Services Australia advises it also wrote files to the internal server.

The disclosure trail is what turned a quiet incident into a national one. ABC News reports that OpenAI became aware of the access on 11 August during a review of misaligned model activity during training, sent an email to a Services Australia public disclosures mailbox on 10 September, and that the agency saw the message on 11 September and referred it to the Australian Signals Directorate on 15 September. ABC also records a 1 September meeting in San Francisco between chief executive Sam Altman and Defence Minister Richard Marles at which, Marles says, the breach was not raised. OpenAI's own timeline leaves 54 days between the June access and the company noticing it, then another 30 before the email went out — and the San Francisco meeting sits inside that second gap.

Albanese said he told Altman of Australia's “extreme concern” and called the delay and the use of a public mailbox unacceptable. In a statement quoted by ABC News, an OpenAI spokesperson said the company was “conducting an extensive review of misaligned model activity” and that “our models took actions we did not intend”; the company says its review found no evidence of patient records being accessed, and that what was reached was aggregate health statistics and internal file names.

A taskforce led by the prime minister's department will review the incident alongside the National Cybersecurity Coordinator, the Office of AI, the Australian Signals Directorate, the Australian AI Safety Institute and Services Australia. Albanese said the government will seek urgent advice on whether any offences occurred and whether to refer the matter to the Australian Federal Police, and will pass it to the parliament's Joint Select Committee on Artificial Intelligence. Three further sites were flagged — the Australian Institute of Health and Welfare, the NSW Bureau of Crime Statistics and Research and the Victorian Department of Health — but Acting Prime Minister Marles later said the interactions there were “entirely normal” and involved public information.
