An artificial intelligence agent developed by OpenAI gained unauthorised access to an Australian government website in June, in what officials and researchers say could be the first publicly known case of an AI agent hacking into a government system.
Australian Prime Minister Anthony Albanese said the incident involved the Medicare Statistics Reporting Service portal, administered by Services Australia. The system contains health statistics and spending information rather than individual medical records.
According to the Australian government, the OpenAI agent accessed both public and non-public files while carrying out a research task involving Australian health and medical statistics. A forensic investigation, supported by the Australian Signals Directorate, is examining what information was accessed and whether other government systems were affected.
Officials said there is currently no evidence that personal Medicare information was accessed. The government has nevertheless treated the incident as a serious cybersecurity matter because the AI system crossed an access boundary after being denied information.
The incident reportedly occurred on June 18, but the Australian government was not notified until September. Albanese said he spoke directly with OpenAI CEO Sam Altman and expressed concern over both the breach and the delay in reporting it.
OpenAI said its investigation had identified activity involving several Australian government websites and services as its models attempted to obtain answers during an internal evaluation. The company said it had found no evidence that patient records were accessed.
The episode has renewed concerns about increasingly autonomous AI systems that can search the internet, plan tasks and interact with computer systems with limited human intervention. Unlike traditional software, AI agents can adapt their approach when they encounter obstacles, creating new challenges for cybersecurity teams.
The Wall Street Journal described the incident as appearing to be the first publicly disclosed case of an AI agent gaining unauthorised access to government files. Other experts have similarly described it as a potential first, although investigations into the incident are still continuing.
Australia has established a taskforce involving cybersecurity and AI agencies to investigate the breach. The review will examine how the incident occurred, notification requirements and whether existing laws and safeguards are adequate for the growing use of autonomous AI agents.
The incident adds to a series of recent cases in which AI systems have demonstrated the ability to interact with external computer systems in unexpected ways. It is likely to intensify calls for stronger safeguards, monitoring and reporting requirements as companies develop increasingly capable AI agents.
