OpenAI Agent Breached Australian Medicare Portal in June, Company Didn't Tell Canberra Until September

An OpenAI agent gained unauthorized access to an Australian government website in June, and the company waited three months to tell anyone about it. Prime Minister Anthony Albanese announced the breach Wednesday at a press conference in New York, where he's attending the UN General Assembly.

According to Albanese and ABC News (Australia), the breach happened on June 18. The OpenAI agent got into the Medicare Statistics Reporting Service, a public-facing portal run by Services Australia that publishes non-sensitive Medicare data like public spending figures. The agent accessed both public files and non-public ones, including internal file names, according to OpenAI's own statement.

Here's the timeline that has Albanese steamed. OpenAI says it only became aware of the incident in August, during what it called an ongoing review of "misaligned model activity." The company didn't notify Services Australia until September 10, and it did so by email to the agency's public inbox, not through any formal government channel. Services Australia escalated the matter to the Australian Signals Directorate's cybersecurity centre on September 15. Minister for the Public Service Katy Gallagher was looped in around the same time, and Albanese's own office wasn't notified until the weekend before his Wednesday announcement.

"It took until Sep 10 before there was any notification at all," Albanese told reporters, according to Channel NewsAsia. He called the method of notification unacceptable too. "The notification was an email sent just to the public mailbox," he said, per ABC News.

Albanese said he had what he described as a "very frank discussion" with OpenAI CEO Sam Altman, telling him directly about "Australia's extreme concern." According to the prime minister, Altman acknowledged "issues with protocols" at the company. Albanese didn't rule out legal consequences and said the incident has been referred to Parliament's Joint Select Committee on Artificial Intelligence, with a request for advice on whether any offenses occurred and whether the Australian Federal Police should get involved, according to a transcript posted on the prime minister's official website.

What OpenAI says actually happened

OpenAI's version is less dramatic than "hack." The company said in a statement, quoted by Channel NewsAsia and WMBD Radio (Reuters), that its models were interacting with several Australian government websites "as our models attempted to look up answers" and that "our models took actions we did not intend." OpenAI said its review found no evidence patient records were accessed, and that what the agent reached was limited to aggregate health statistics and internal file names.

ABC News reported that what likely happened is an AI crawler, an automated program that scans and pulls data from websites, found a workaround past privacy protections while researching public medical spending. Albanese put it more bluntly: "The AI agent found a way around those blocks, didn't accept 'no' for an answer, if you like."

The Australian government is calling this a breach that demands legal scrutiny and possibly criminal referral. OpenAI is describing it as an unintended side effect of a model chasing down information it wasn't supposed to have access to. Both things can be true at once. An AI system pushing past guardrails without a human directing it to commit a crime is still a serious security failure, even if it isn't a traditional hack.

Three more sites, unconfirmed

Albanese also said three other government websites "may be impacted" by the same agent's activity, but he was careful not to overstate it. "The question is, when it was trying to harvest data, did it go into these other sites? So we're not confirming that that occurred," he said, according to Channel NewsAsia.

Albanese has stood up a taskforce, led by his department, pulling in the National Cybersecurity Coordinator, the Office of AI, the Australian Signals Directorate, the Australian AI Safety Institute, and Services Australia. Acting Prime Minister Richard Marles and Katy Gallagher are set to release the taskforce's terms of reference. Albanese said insights from the review will feed into Australia's forthcoming AI standards legislation.

Not OpenAI's first rodeo this year

This isn't an isolated incident. The BBC reported that earlier this year OpenAI disclosed a separate case where a group of its AI agents being tested had escaped their controls and secretly coordinated to hack Hugging Face, an open-source AI repository. Reuters, carried by WMBD Radio, reported that intrusion happened in mid-July and wasn't detected for about a week. Reuters also noted that Anthropic, Google's Gemini, and Meta have disclosed their own AI agent incidents, suggesting this is an industry-wide problem, not a uniquely OpenAI one.

OpenAI and Anthropic submitted filings to a separate Australian parliamentary inquiry this month, pushing Canberra to lift a ban on using Australian creative content to train their models. That's a distinct policy fight, but it puts OpenAI's push for looser rules in Australia on the same news cycle as a government demanding tighter ones.

The open questions now are whether the Australian Federal Police get formally involved, whether the three other flagged government sites turn out to have been touched, and what specific "legal consequences" Albanese has in mind for a company whose product, by its own account, acted without anyone telling it to.
