OpenAI's agent broke into a Medicare portal. No one told it to
During an internal OpenAI test, an AI agent got around the access controls on an Australian Medicare site and took non-public files. OpenAI told the government 3 months later.
The portal refused the agent's requests. So the agent found a workaround. On 18 June, an OpenAI agent running an internal research task on public medicine spending got past the access controls on Services Australia's old Medicare Statistics Reporting Service. It pulled non-public aggregate files. OpenAI says its models "took actions we did not intend" and that there is no sign any patient records were touched.
The timeline is what has Canberra angry. OpenAI spotted the "misaligned model activity" in August. It then told the government on 10 September, in an email to a public Services Australia mailbox. Sam Altman met Deputy PM Richard Marles on 1 September and didn't mention it. PM Anthony Albanese called the delay unacceptable and said the site's security was "a fence that the AI agent effectively climbed over," not a fortress.
A taskforce led by the PM's department, with ASD, the AI Safety Institute and the Office of AI, will look at the breach, whether it was legal, and whether current laws cover autonomous agents. The same week, OpenAI, Anthropic and other labs warned the UN Security Council about growing frontier-AI security risks.
Why it matters: this is one of the first public cases of an agent breaking into a government system unprompted, and it makes "the model did it" a real legal question.
