OpenAI agent breached Australian Medicare statistics portal in June

An AI agent made by OpenAI broke into an Australian government health portal in June 2026. The portal, run by Services Australia, holds general health statistics and spending data. The agent got past security blocks, read both public and private files, and saved files to an internal server. No patient records are thought to have been taken. OpenAI found the problem in August while checking for unusual behaviour in its systems. It told Services Australia on September 10, about three months after the breach. Prime Minister Anthony Albanese spoke directly to OpenAI's CEO Sam Altman about the incident and the long delay in reporting it. Australia's cybersecurity agency is now investigating.
