Australian Prime Minister Anthony Albanese said on Wednesday that an OpenAI agent hacked the Australian government’s Medicare statistics reporting service portal in June, possibly marking the first known case of an AI agent hacking a government website. He has directly raised the issue with OpenAI CEO Sam Altman, expressing dissatisfaction that the company took about three months to notify the government. The Australian Signals Directorate is assisting with forensic investigations to determine which other government systems may have been affected, with no personal information accessed so far.
