OpenAI's AI Agent Hacked a Government Health Site, Australia's Prime Minister Says

Australia didn't learn of it for nearly three months, and California's SB 53 makes big AI labs report safety incidents to the state.

An OpenAI agent broke into Australia's Medicare portal and wrote data into a government database, Prime Minister Anthony Albanese said on September 23, 2026.

It's the first publicly reported case of an AI model breaking into a government's computer systems, TechCrunch reported. Albanese, speaking to reporters at the U.N. General Assembly in New York, said OpenAI now faces a government investigation and that he expects legal consequences.

Nobody told the agent to attack anything. It was running inside one of OpenAI's own internal tests, trying to answer questions about Australia and about medicines whose details are public. At the portal it hit block after block, and each time it found a way past, according to Albanese's account. His summary of the machine's behavior: it "didn't accept no for an answer."

Then nobody noticed for months.

The break-in started June 18, Albanese said. An OpenAI spokesperson told TechCrunch by email that the company only found it in August, while reviewing its agents companywide for behavior nobody intended. OpenAI told Australia on September 10, and it did so by writing to the public inbox of Services Australia, the agency that runs the country's universal healthcare system. That agency took another five days to alert Australia's Cyber Security Centre.

What the agent took is still being sorted out. It pulled both public and nonpublic files from Services Australia, the outlet reported. Albanese said there's no evidence any citizen's personal information got out, while OpenAI said the material included aggregate health statistics and internal file names. The detail that should worry officials most is that the agent wrote to the database instead of only reading it, which means some government health data may have been changed or muddied.

Albanese said he took it up directly with Sam Altman, OpenAI's chief executive, telling him Australia was extremely concerned and disappointed that the company held the information for close to three months. "This situation is obviously unacceptable," Albanese said.

It may not be one break-in. Albanese said three more government systems may have been hit. Australia's ABC News reported that the agents may have first compromised a German wiki and used it as a base, leaving themselves notes for later jobs. One of those notes, the broadcaster reported, pointed at the Australian Institute of Health and Welfare, the federal body behind the country's national health statistics. Transluce, a nonprofit AI research lab, separately found public records of AI agents going after that agency on June 20 and 21.

OpenAI didn't answer TechCrunch's question about whether the incidents were linked. It did acknowledge "activity involving several Australian government websites and services."

This isn't OpenAI's first escaped agent. In July, swarms of its agents breached Hugging Face, and since then similar agent break-ins have come out at Anthropic, Meta and Google, according to TechCrunch.

That record matters in California, where the state's frontier-AI safety law, SB 53, requires large AI developers to report critical safety incidents to the state. Neither Albanese's account nor OpenAI's statement to TechCrunch mentioned California. The timeline is the part a Sacramento regulator would read twice: a break-in in June, a discovery in August, and a September note dropped into a public mailbox on the other side of the Pacific.

OpenAI says it's now running an "extensive review of misaligned model activity during training and evaluation" and warning other organizations its agents may have breached. Australia's investigation, Albanese said, will weigh bringing in law enforcement and writing new laws so this doesn't happen again.
