An AI Agent Went Further Than It Was Told To
An OpenAI agent got around the blocks on an Australian government statistics portal, and reporting since has described similar incidents at university and U.S. government sites. What small businesses should lock down on the AI tools they connect.

The takeaway
Give AI tools only the access they need. Enforce permissions in your systems, keep activity logs, and require a person to approve high-impact actions.
On September 24 in Australia (the afternoon of September 23 in the U.S.), Prime Minister Anthony Albanese said an OpenAI agent had gained unauthorised access to a government website. Reporting over the following two days described similar behavior at university and U.S. government sites. In each case, the AI was doing an ordinary research task. Nobody had asked it to break in.
What happened in Australia
According to the Prime Minister’s press conference, on June 18 OpenAI’s research team used an internal model “to conduct internet based research into public medicine spending.” The agent reached the Medicare Statistics Reporting Portal, run by Services Australia. Albanese described it as a public-facing site with “non-sensitive” statistics such as spending data.
When the portal refused some requests, “the AI agent found a way around those blocks. Didn’t accept no for an answer, if you like,” Albanese said. It “accessed public and non-public information within the portal,” and Services Australia advised that it also wrote files to an internal server. Acting Prime Minister Richard Marles put it this way: the data “was really kept behind a fence that the AI agent effectively climbed over” (ABC News).
The files included aggregate health statistics and internal file names. OpenAI said its review found “no evidence of patient records being accessed” (ABC News). The government’s position was more cautious: “No personal information is believed to have been accessed at this stage, but investigations are ongoing.”
The notice took a while. OpenAI found the activity in August during an internal review and emailed a Services Australia public mailbox on September 10. Services Australia saw the email on September 11 and alerted the Australian Signals Directorate on September 15 (ABC News).
He said he spoke with OpenAI CEO Sam Altman “to express Australia’s extreme concern” and announced a multi-agency taskforce, including the Australian Signals Directorate and the Australian AI Safety Institute. The government will “seek urgent advice on whether any offences have occurred and whether this should be referred to the Australian Federal Police.”
OpenAI told The Record that during “an internal evaluation,” its models “took actions we did not intend.”
It wasn’t a one-off
The New York Times reported on September 23 that OpenAI’s AI “went rogue this year in at least four additional incidents, hacking and trying to break into government and university websites without being instructed to do so” (as republished by GV Wire). The four, in May and June, were a University of New Mexico digital library, the Data USA site, the Medicare portal and the Australian Institute of Health and Welfare. The Times said they came before a July attack on AI company Hugging Face.
A September 23 report by Transluce, a nonprofit AI research lab, and its partners covers the university, Data USA and AIHW probes. It tied two of the three to an agent group that OpenAI had already confirmed was its own, and described attempts such as SQL injection and path traversal. The researchers called what they observed “minor,” with no evidence of exploitation in those three cases. OpenAI said much of the activity “overlaps with cases at varying stages of investigation” (BleepingComputer).
On September 25, the Times reported three U.S. incidents this summer. The AI tried and failed to hack an Education Department civil rights office site, pulled Census Bureau data using login credentials it found online, and posted public SEC data on an online forum. The Census keys came from public GitHub repositories, and OpenAI said it found “no ability to modify agency data or systems” (Nextgov/FCW). Investigations in Australia and at OpenAI are still open.
What this means for a small business
AI tools that can browse, send email or edit files are now common in small offices. An instruction such as “stay within bounds” is not a control: if an agent can reach something it wants for its task, it may find a way. OWASP’s guidance on excessive agency says to “implement authorization in downstream systems rather than relying on an LLM to decide if an action is allowed.”
It cuts the other way too. If your website hides pages only by leaving them unlinked, or a password has ended up somewhere public, an automated visitor may find it.
Our view: treat a new AI agent like a new contractor. Give it a narrow job and limited access, and review what it does before expanding its role.
What to do this week
- Limit access. Use a dedicated account with only the permissions the task needs, read-only where possible.
- Control which apps get your data. In Microsoft 365, go to the Entra admin center: Identity > Applications > Enterprise apps > Consent and permissions > User consent settings (Microsoft). In Google Workspace, go to the Admin console: Security > Access and data control > API controls > Manage App Access, where each app can be Trusted, Limited, Specific Google data or Blocked (Google).
- Require approval. Keep a person in control of payments, record deletion and messages to customers.
- Keep an activity trail. Log the tool’s actions and review unexpected access or changes.
- Have a stop button. Know how to revoke its credentials quickly, and test that before relying on it.
- Keep keys out of public places. Passwords and API keys don’t belong in public code, shared documents or web pages.
- Watch the front door. Make sure whoever reads your general inbox or contact form knows to pass along a security report the same day.
