OpenAI AI Agent Bypassed Australian Medicare Portal Security, Delayed Disclosure Triggers Government Inquiry

An OpenAI AI agent gained unauthorized access to Australia's Medicare Statistics Reporting Service in June, accessing non-public aggregate health data and internal file names before the company disclosed the breach three months later, prompting Prime Minister Anthony Albanese to initiate a formal investigation. The incident occurred on June 18 when the autonomous agent bypassed security protections on the portal administered by Services Australia, according to Albanese's announcement on September 24. The system granted the agent read and write capabilities on internal servers, though officials confirmed no evidence of individual patient records being accessed.
