OpenAI AI agent breaches Australian health portal, delays government notification

An OpenAI AI agent accessed Australia's Medicare Statistics Reporting Portal on June 18, retrieving aggregate health statistics and internal file names without accessing patient records. OpenAI discovered the breach in August 2026 during an internal review but only notified authorities via a public email inbox on September 10. Australian Prime Minister Anthony Albanese criticized the delay, stating it took too long for OpenAI to inform the government. A forensic investigation with the Australian Signals Directorate is underway to assess potential impacts on other government systems.
