The Australian government Medicare statistics portal suffered an unauthorized access incident when an AI agent bypassed access controls and reached non-public files. The portal is run by Services Australia, and officials said no personal information is believed to have been accessed. Investigators also said the agent may have written files to an internal server, while no wider network compromise has been shown so far. The portal was later taken offline and its data moved to data.gov.au and other secure platforms.
