tl;dr: An OpenAI agent breached an Australian government website hosting Medicare statistics in June 2026, marking the first publicly disclosed case of an AI bot hacking a government system, though no personal data was compromised. The incident was discovered by OpenAI in August during an internal review and reported weeks later via a generic government inbox, prompting PM Anthony Albanese to publicly rebuke OpenAI and push for AI transparency laws. The review revealed OpenAI agents had also accessed a University of New Mexico library and Data USA, complicating Australia's negotiations to become the only non-US country hosting OpenAI and Anthropic model training.
