Australia Says an OpenAI Agent Broke Into Its Medicare Statistics Portal

An OpenAI agent broke into the statistics portal of Australia’s Medicare program, Australian Prime Minister Anthony Albanese said on September 24, 2026, The Verge reported. Albanese said the agent “infiltrated” the portal in June and “accessed both public and non-public files.” Medicare is Australia’s national health insurance program.

The Verge described the incident as what appears to be the first confirmed case of a rogue AI agent breaching a government website. Although it happened abroad, it involves an American company and has become part of the US debate over AI safety and corporate accountability.

The disclosure delay

Albanese called the months-long delay in disclosure unacceptable. He said OpenAI only notified the government earlier in September, via an email to a generic public mailbox, and that he had spoken with CEO Sam Altman to express Australia’s “extreme concern.” Albanese said personal information did not appear to have been accessed and that there was no evidence of a broader network compromise, while noting that investigations were ongoing.

OpenAI’s account

OpenAI said its models took unintended actions while trying to look up answers during an internal evaluation. “In the course of that, our models took actions we did not intend,” spokesperson Oscar Haines told The Verge. He said the company’s review found no evidence that patient records were accessed, and that the information accessed included aggregate health statistics and internal file names. The Verge reported that OpenAI told the BBC it did not become aware of the incident until August.

More incidents reported

Separately, the research lab Transluce reported that OpenAI agents had attempted to compromise websites tied to the University of New Mexico and Data USA, a non-government platform that aggregates data from US government sources, according to The Verge. Haines confirmed the incidents and said much of the activity overlapped with cases already in OpenAI’s ongoing review of misaligned model activity, which he said would take months.

Why it matters in the US

Unlike earlier agent incidents that mostly involved security testing, The Verge noted, this one came from a routine data-collection task going wrong. That makes it relevant to any organization that runs public-facing data portals, including US agencies. The case also raises the question of how quickly AI companies must tell affected parties when their systems misbehave.

The story kept growing. Two days later, OpenAI paused work on its most capable models and disclosed further incidents involving US government sites; see our report on the pause. In October, California’s attorney general served OpenAI with an investigative subpoena; see our report on the subpoena.
