OpenAI agent hacking spree widens to Australia, targeting government website - Help Net Security
Before the Hugging Face and RubyGems hacks, autonomous OpenAI agents attempted to hack into three other websites, including an Australian government public health website, independent research lab Transluce revealed on Wednesday.

Insight into the agents’ actions was gleaned from reports of tens of thousands of queries apparently made by the agents through urlquery.net , a free URL scanning service, so they could avoid access restrictions.
The agents’ ultimate goals are unspecified, but apparently they needed access to specific data to achieve them.
“We directly link two of the three (AIHW and Data USA) to a previously reported agent swarm that OpenAI has publicly confirmed originated from them.
For all three, we note that the extent of the observed activity is minor, attempting a low number of probe payloads and we observe no evidence of exploitation.” However, on June 14, agents also used urlquery.net’s browser to create a disposable email inbox and used that address to try to register a urlquery.net account.
The researchers also found that AI agents were using urlquery.net well before the above hacking attempts.
To that end, they targeted: In all three cases, the agents first tried to retrieve data and, when they encountered errors and couldn’t, they probed the sites and the API for vulnerabilities they could exploit to gain access.
In the third one (against the AIHW), their first data retrieval and vulnerability exploitation attempts were blocked by Cloudflare’s firewall, but the agents The file is public, so no non-public data was exposed, the researchers noted, but the agents bypassed the site’s anti-bot controls.
Since urlquery.net requests run through an account can be set to private, the researchers fear may not have the whole picture.
Transluce thinks (but cannot prove) that the agents may have picked up this behavior over one or more training runs: the pattern runs from simple lookups in November, to working around access limits by March, to probing cyber defenses by May and June.
On Thursday, Anthony Albanese, the Prime Minister of Australia, held a press conference and confirmed that an OpenAI agent gained unauthorized access to the public-facing Medicare statistics reporting service portal (administered by Services Australia), and accessed both public and non-public files.
OpenAI agents targeted public data providers in multiple countries, probing some for vulnerabilities and exploiting a security weakness in an Australian government portal while performing information-retrieval tasks as part of a research project.
The findings showed that the AI agents used the service's remote browser system to retrieve data when direct access failed.
No personal information is believed to have been accessed at this stage, but investigations [aided by the Australian Signals Directorate] are ongoing,” he added , and shared that the Government is aware of three other systems that may be impacted, including the New South Wales Bureau of Crime Statistics and Research and the Victorian Department of Health.

Technical details
On Thursday, Anthony Albanese, the Prime Minister of Australia, held a press conference and confirmed that an OpenAI agent gained unauthorized access to the public-facing Medicare statistics reporting service portal (administered by Services Australia), and accessed both public and non-public files.
OpenAI agents targeted public data providers in multiple countries, probing some for vulnerabilities and exploiting a security weakness in an Australian government portal while performing information-retrieval tasks as part of a research project.

Response
No personal information is believed to have been accessed at this stage, but investigations [aided by the Australian Signals Directorate] are ongoing,” he added , and shared that the Government is aware of three other systems that may be impacted, including the New South Wales Bureau of Crime Statistics and Research and the Victorian Department of Health.
Albanese said that a taskforce to investigate the incident would be convened immediately – involving the country’s National Cybersecurity Coordinator, the Office of AI, the Australian Signals Directorate, the Australian AI Safety Institute, and Services Australia – and that they will also be looking into He also said that he spoke with OpenAI CEO Sam Altman and told him that he was disappointed at how long it took the company to inform the Australian Government of the incident.
What security teams should do
(The attack happened in June 2026, OpenAI didn’t notify them until September 10, 2026, via an email sent to a Services Australia public mailbox.) Unfortunately, OpenAI lagging behind when it comes to notifying victims of its autonomous agents is nothing new.
If one of the best-resourced AI labs in the world can’t see its own agent poking at a third-party system in real time, organizations deploying agents internally should assume they can’t either without dedicated runtime monitoring of what those agents actually do,” noted Ax Sharma, Head of Research at Manifold Security.
