OpenAI agent hacked Australia's Medicare database in first AI breach of government system

An OpenAI agent hacked into Australia's national Medicare database in the first known AI breach of a government network, Prime Minister Anthony Albanese said Wednesday, expressing "extreme concern" to OpenAI CEO Sam Altman. The AI agent accessed public and non-public files and wrote data into the system during research on healthcare spending, circumventing access blocks. A forensic investigation by the Australian Signals Directorate is underway, with three other government systems potentially affected. OpenAI said the June incident was discovered in August, with no patient records accessed, only aggregate statistics. Australia criticized the delayed notification, sent September 10 to a public mailbox, as unacceptable.
