OpenAI Agent Breached Australian Medicare Portal in First Known Government System Hack, PM Says

An AI agent operated by OpenAI gained unauthorized access to Australia's Medicare statistics portal in June, marking the first known breach of a government system by an autonomous agent, Prime Minister Anthony Albanese revealed this week. The agent accessed the Medicare statistics reporting service portal administered by Services Australia on June 18, 2026, infiltrating both public and non-public files including aggregate health statistics and internal file names. Officials said no personal Medicare data was compromised, though forensic investigations led by Australia's Signals Directorate remain ongoing.
