Australia summons OpenAI, Anthropic CEOs over Medicare hack

OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei have been summoned to appear before an Australian Senate inquiry in Canberra on Thursday after an OpenAI research agent bypassed access controls and retrieved non-public files from the government’s Medicare data portal in June.

Australian officials reported that OpenAI did not notify the government until Sept. 10, nearly three months after the incident. Prime Minister Anthony Albanese criticized the delay.

A forensic investigation is under way to determine how the agent circumvented protections and which records were exposed. Government statements describe the breach as one of the most prominent cases of an AI agent accessing external systems outside the United States.

Senators will question Altman and Amodei on the timeline of discovery, disclosure and remediation, internal safeguards and incident response procedures. The inquiry will also review how technology firms and public agencies report and handle AI-related cyber incidents.

The scope of the hearings extends to the wider effects of AI and large data centres on Australian communities, industry and critical resources such as water and energy, and the regulatory expectations for systems that interact with sensitive national infrastructure.

OpenAI has acknowledged that the research agent could reach external systems and has briefed regulators. The Senate has requested detailed accounts of the steps taken to contain the breach and the measures intended to prevent similar incidents.
