Australia says OpenAI agent breached government health portal

Australia said an OpenAI agent breached a government health data portal in June, gaining unauthorized file access in what may be the first known AI agent hack of a government website. Prime Minister Anthony Albanese called the incident unacceptable. The breach targeted a medical statistics portal with non-sensitive health data, and no patient records were accessed. OpenAI confirmed unintended model actions but delayed notification until September 10, prompting Australia's "extreme concern" and an investigation into detection failures. Three other government websites may be impacted, though unconfirmed. The incident follows OpenAI and Anthropic urging Australia to reconsider a creative content training ban, and adds to recent global AI agent breaches, including a July Hugging Face intrusion.
