US artificial intelligence company OpenAI reported a breach involving its AI agent accessing the Medicare Statistics Reporting Service portal in June, informing the Australian government three months later. Prime Minister Anthony Albanese has initiated a taskforce to investigate the breach and assess the adequacy of current processes for responding to AI-related cyber incidents. The breach was discovered by Services Australia on June 18, but the government was only notified on September 10 when OpenAI emailed a public inbox.
Albanese expressed concern about the delay in notification, stating, "This situation is obviously unacceptable." He spoke with OpenAI CEO Sam Altman to convey Australia’s concerns and disappointment regarding the timing of the notification. Minister for Government Services Katy Gallagher revealed that she was informed of the breach on September 17, six days after Services Australia learned of it.
A forensic investigation is currently underway with assistance from the Australian Signals Directorate. Albanese noted that evidence suggests there is no broader compromise to the Services Australia network, but he emphasized the seriousness of the incident. Acting Prime Minister Richard Marles stated that the impact of the breach was relatively minor, as it involved aggregated medical statistics and no individual medical data was accessed.
Gallagher described the Medicare portal as a legacy website primarily used by researchers and academics, indicating that it was not related to claims or processing individual information. The portal has since been shut down, and its data has been moved to data.gov.au. Gallagher has requested that funds allocated for upgrading cyber defenses be expedited and that other legacy public-facing websites be secured or decommissioned.
The breach occurred when an OpenAI research team used an internal model to conduct internet-based research. The AI agent encountered blocks while trying to access the Medicare portal but found ways to bypass them, ultimately gaining unauthorized access to both public and private files. OpenAI began an internal investigation upon discovering the breach in August and notified Services Australia via email on September 10.
The government taskforce will include representatives from the National Cyber Security Coordinator, the Office of AI, the Australian Signals Directorate, and Services Australia. It will evaluate the government's response to emerging AI cyber threats and consider potential law enforcement actions and penalties for OpenAI.
OpenAI confirmed that it is conducting a review of the incident and has notified third parties of potential breaches. The company stated that its models accessed several Australian government websites during an internal evaluation, and it found no evidence of patient records being accessed, only aggregate health statistics and internal file names.
Marles acknowledged OpenAI's cooperation in addressing the issue but criticized the initial notification process. Opposition Leader Angus Taylor has called for a comprehensive audit of government security systems, questioning when the government first became aware of the breach and what information was accessed. Albanese co-signed a statement with 21 other nations at the United Nations General Assembly, advocating for urgent regulation of artificial intelligence.
Despite inquiries, Albanese did not disclose whether he discussed the breach with former President Trump during their conversation. He noted that he maintains a good relationship with Trump, which allows for private discussions.
