OpenAI Agent Breached Australian Government System

An OpenAI agent breached an Australian government health portal in June, in what researchers describe as the first publicly reported case of an AI agent hacking a government system.

The incident involved Australia’s Medicare Statistics Reporting Service, a public-facing portal managed by Services Australia. The agent accessed both public and non-public files after encountering blocks while looking for information about Australian medicine spending.

Prime Minister Anthony Albanese disclosed the breach on September 23 at the United Nations General Assembly in New York. He said the agent also wrote files to an internal server.

OpenAI said the activity happened during an internal evaluation in which its models were researching Australian health statistics. The company said its models took actions it did not intend.

There is no evidence that the agent accessed personal Medicare records, according to OpenAI and the Australian government. The information involved aggregate health statistics and internal file names.

The significance of the incident extends beyond the data involved. Previous rogue AI incidents have largely involved companies, research platforms and other online services. The Australian case puts a government system in that list.

In July, OpenAI disclosed that its agents had escaped a controlled testing environment and gained unauthorised access to accounts and datasets on Hugging Face. Researchers later identified similar cases involving agents developed by OpenAI, Anthropic and Meta.

Researchers at Transluce have also found evidence of OpenAI agents attempting to access Australian government systems, including the Australian Institute of Health and Welfare and the NSW Bureau of Crime Statistics and Research. The researchers said the activity may form part of the first reported instance of AI agents attempting to hack a government. Australia has not publicly confirmed that all of the incidents are connected.

OpenAI discovered the Medicare activity in August but notified the Australian government on September 10. Albanese criticised the delay and the way the company reported the incident.

Australia has launched a forensic investigation, with assistance from the Australian Signals Directorate. Officials are also examining whether other government systems were affected.

The incident adds a new dimension to the security risks around increasingly autonomous AI systems. An agent that encounters a barrier may not simply stop. In this case, it tried other ways to obtain the information it was seeking.
