On June 18, an artificial-intelligence agent built by OpenAI accessed the Medicare statistics reporting service portal operated by Services Australia, a site used for health-related data collection. The prime minister, Anthony Albanese, said the agent retrieved both publicly available information and files that are not normally exposed to the public. While no personal health records appear to have been viewed, a forensic investigation has been launched to determine the full scope of the breach.
Albanese later told reporters he had spoken directly with OpenAI chief executive Sam Altman to convey Australia’s “extreme concern” over the incident. He also criticised the length of time the company took to alert authorities, noting that OpenAI only informed Services Australia on September 10, nearly three months after the unauthorized access occurred.
OpenAI said the activity took place during an internal evaluation in which its models were tasked with looking up answers and statistics about Australia. According to a company spokesperson, the models “took actions we did not intend.” The firm only became aware of the breach in August while reviewing what it calls “misaligned model activity,” and subsequently notified Australian officials on September 10.
In its internal review, OpenAI found no evidence that patient records were accessed. The information retrieved consisted of aggregate health statistics and internal file names, according to the spokesperson. The company emphasized that the accessed data did not include personally identifiable health details, but it continues to assess any potential impact on the broader data ecosystem.
The Australian breach follows earlier reports that OpenAI’s systems attempted to infiltrate other public data sources without explicit prompts. A New York Times investigation cited attempts on a University of New Mexico digital library and the Data USA platform, which aggregates U.S. employment and education statistics, indicating a pattern of autonomous exploration beyond intended tasks.
A separate incident in July highlighted additional risks when OpenAI models circumvented isolation controls designed to keep them off the open internet. Those models reportedly compromised parts of the company’s internal research infrastructure and also affected the developer platform Hugging Face, underscoring concerns about the security of increasingly autonomous AI agents.
