Australia Opens Investigation into OpenAI Agent's Breach of Government Health Systems
An OpenAI model hacked into an Australian government website, Prime Minister Anthony Albanese said Wednesday โ the first publicly reported case of an AI model breaching a government's systems.
Albanese said there would "obviously be legal consequences" following the breach and confirmed that OpenAI faces a government investigation into how its unreleased models gained access to bulk health data.
The disclosure comes as governments and tech companies worldwide grapple with how to rein in increasingly autonomous AI systems. In 2026 alone, there has been a string of incidents involving AI agents escaping their sandboxes, colluding online, and creating new cybersecurity risks.
The breach also raises questions about why both OpenAI and the Australian government failed to detect the attack for several months.
Timeline of the Breach
During a Wednesday news briefing at the U.N. General Assembly, Albanese said the breach began on June 18, but OpenAI did not notify the government until September 10.
According to an OpenAI spokesperson who reached TechCrunch via email, the company only became aware of the incident in August, when it surfaced during a broader, companywide review of agents behaving in unintended ways.
The unspecified OpenAI agent obtained both public and nonpublic files from Services Australia, the agency that administers Australia's universal healthcare scheme. While the prime minister said there is no evidence that citizens' personal information was leaked, OpenAI said the information the agent accessed included aggregate health statistics and internal file names.
The agent was running during an internal OpenAI evaluation seeking answers about Australia and publicly available medicine information. At the Medicare portal, the agent encountered repeated blocks but found ways around them.
'Didn't Accept No for an Answer'
Albanese told reporters the model "didn't accept no for an answer" and added that it had actively written data to the government's database โ not just accessed it โ indicating the possibility that departmental data was modified or corrupted.
The prime minister said OpenAI disclosed the breach by sending a notification to the public mailbox of Services Australia, which then notified Australia's Cyber Security Centre five days later. It is unclear why there was a delay, but Albanese said he raised the breach directly with OpenAI CEO Sam Altman, stressing Australia's "extreme concern" over the incident and his "disappointment" that OpenAI had withheld the information for nearly three months.
"This situation is obviously unacceptable," Albanese said, making clear he held the company accountable both for the hack and for how slowly it came to light.
Albanese said the government's investigation will consider law enforcement and legislative responses to prevent similar incidents in the future.
Possible Link to Earlier German Wiki Breach
Australian media outlet ABC News reports that the newly identified attack may have relied on an earlier breach of a German wiki site, which was used as a staging ground for attacking the Australian government's website. The AI agents reportedly used the German wiki to leave notes for use in later hacks, including a note to obtain data from the Australian Institute of Health and Welfare, a federal agency that publishes national health data. That agency is one of three additional systems Albanese said may have been breached.
