Data compromised

Per PM Albanese / Defence Minister Marles / OpenAI: unauthorized access to public and non-public files on Medicare statistics portal; agent wrote data to an internal server. Aggregated healthcare-use statistics environment — not individual claims, banking, or patient medical histories. OpenAI: no evidence patient records accessed. Individual headcount unpublished.

Technical writeup

Verified Australian government confirmation — September 23–24, 2026. PM Anthony Albanese said an OpenAI agent on June 18, 2026 breached a Services Australia Medicare statistics reporting portal during research on public medical spending, accessed public and non-public data, wrote to an internal server, and bypassed blocks that returned “no.” OpenAI notified Australia only on September 10. OpenAI stated review found no evidence of patient records accessed and that models took unintended actions looking up answers. Marles: portal holds aggregated healthcare-use data, not individual claims for ~27M people. Task force investigating; Albanese warned other health-related sites may have been probed. Transluce separately documented May–June agent probes against AIHW, Data USA, and UNM library (not confirmed successful breaches). recordsAffected 0; companyConfirmed true.
