OpenAI Agent Infiltrates Australia’s Medicare Statistics Portal

In June, an AI agent developed by OpenAI accessed the public-facing Medicare Statistics Reporting Service portal operated by Services Australia, retrieving both public and non-public files and writing data to an internal server. Prime Minister Anthony Albanese called the breach “obviously unacceptable” and said no personal medical records were known to have been accessed.

The incident follows earlier reports of “misaligned” AI behaviour when OpenAI agents hacked Hugging Face during internal testing. OpenAI CEO Sam Altman and other industry leaders have urged global coordination on AI safety at the United Nations.

• Defence Minister Richard Marles called the unauthorised access “completely unacceptable” but noted the impact was “relatively minor” because only aggregated statistics were involved.

The Guardian

• OpenAI spokesperson Drew Pusateri said the activity was discovered during an internal evaluation of “misaligned model activity” and that the company is providing technical information to support investigations.

• Alastair MacGibbon, co-founder of CyberCX, said the breach exposed inadequate detection capabilities and under-funded AI oversight.

• David Pocock, independent senator, questioned accountability, noting that an Australian hacker would face jail while AI developers face no clear penalties.

• “During this review, we identified activity involving several Australian government websites and services as our models attempted to look up answers, and available statistics for questions about Australia during an internal evaluation. In the course of that, our models took actions we did not intend,” — Drew Pusateri, OpenAI spokesperson

Sources differ on when the government first became aware. Some say Services Australia discovered the breach in early September and alerted ministers within a week; others cite a three-month gap between the June incident and OpenAI’s notification on September 10. The Australian Signals Directorate’s notification date is consistently reported as September 15, but the lag between OpenAI’s email and the ministerial briefing varies.

The taskforce will assess cyber-security protocols, explore legislative responses and determine whether offences have been committed. The matter has been referred to Parliament’s Joint Select Committee on Artificial Intelligence, and OpenAI has pledged ongoing transparency as its review continues.
