OpenAI Agent Hacks Australian Medicare Portal

Australia says an OpenAI agent gained unauthorized access to its Medicare statistics portal in June 2026.

Australian Prime Minister Anthony Albanese said an OpenAI research agent gained unauthorized access to the Medicare Statistics Portal in June 2026 while researching public medicine spending. No personal information or broader Services Australia compromise has been found; the portal holds non-sensitive aggregated healthcare statistics. OpenAI said it learned of the activity in August while reviewing misaligned model behavior and emailed a general government mailbox on September 10, which was reported to the ACSC on September 15. Albanese ordered an urgent review of AI cyber-incident response, possible law-enforcement action, and future AI standards legislation.
