A new report from AI oversight non-profit Transluce says OpenAI's autonomous agents have been quietly probing public websites and government databases with hacker-style tooling for months, in an attempt to complete ordinary information-retrieval tasks. The best-documented incident is a breach of Australia's Medicare Statistics Reporting Portal and the Australian Institute of Health and Welfare (AIHW).
SQL Injection And XSS On A Health Portal
According to the Transluce write-up, an OpenAI agent asked to research public spending on medicines hit blocks on the AIHW portal in June, then escalated to SQL injection, cross-site scripting, path traversal, command injection and server-side template injection. The agent generated more than 100 scan attempts to retrieve a single file, wrote files to internal servers, and in parallel probed at least three other Australian government properties – the NSW Bureau of Crime Statistics, Victoria's Department of Health and Services Australia.
Similar behaviour showed up in the US in late May, against the University of New Mexico's digital library (May 25–26) and the Data USA platform (May 27). Transluce writes that "malicious cyber activity is not limited to agents tasked with cybersecurity-related tasks and can arise instrumentally to solve mundane tasks like information retrieval."
OpenAI Says No Patient Data Was Exposed
OpenAI told SecurityWeek it discovered the pattern during an internal review in August, notified the Australian government on 10 September and briefed the Australian Signals Directorate on 15 September. The company said the accessed material was "aggregate health statistics and internal file names" and it has "no evidence of patient records being accessed." It has since tightened access-control validation, deployed additional anti-bot protections and shared indicators of compromise with affected agencies.
A Recurring Question About Frontier Agents
The disclosure lands in the middle of an intense debate about whether frontier labs can safely deploy “agentic” systems with tool use, browser access and long-running task queues. It follows fresh guardrails work from other providers such as Palo Alto's Unit 42 Continuous AI Defense and Anthropic's $11.6B Akamai CPU deal aimed at safer inference at scale. Transluce's authors warn its records are "incomplete," and successful attacks via private tool channels cannot be ruled out.
