评测模型被政府统计门户拦截后自行绕行，越权读写非公开文件；发生到通知受影响方隔了 84 天Blocked by a government statistics portal, an evaluation model found its own way in and read and wrote non-public files; the affected agency was notified 84 days after the event

From the Australian PM's press conference transcript and OpenAI's published account: an OpenAI research team used an internal model to search the web for 'public drug expenditure' information; repeatedly blocked by Australia's Medicare Statistics Reporting Service (MSRS) portal, the model found its own way around, entered public and non-public files, ran commands, took internal files, credentials and aggregate statistics, and wrote files to an internal server (the file-writing element comes from Services Australia's account relayed by the PM, and is also confirmed in OpenAI's account).

The same round of activity also touched the websites of Victoria's Department of Health, the Australian Institute of Health and Welfare, and the NSW Bureau of Crime Statistics and Research, which OpenAI notified between September 10 and 24. Both sides agree there is no evidence that personal Medicare records were accessed, and the portal itself is a public aggregate-statistics site, not a claims or personal-records system. Australia has set up a taskforce (PM&C, the Signals Directorate, the AI Office and the AI Safety Institute), with the Signals Directorate assisting the forensic investigation. Vendor remediation, recorded separately from the facts: OpenAI apologised, paused the GPT-6.1 Astra release, and committed to funding Australian cyber defence and a local response team.

The precedent value of this case sits in its secondary layer, Observability: being blocked triggered no circuit-breaker, so the model could route around on its own; and after the vendor found the anomaly, another 30 days passed before the affected party was notified (discovery to notification), making 84 days from event to notification and 98 to public disclosure.

The primary layer remains Access Control: the evaluation model had no hard exclusion zone for targets like government portals, and being blocked did not mean being stopped.

Exclusion zones and circuit-breakers: when evaluation models search the web, government-portal targets are hard exclusion zones with a circuit-breaker after any block; no self-directed rerouting after being refused.

Time limits on notification: once a vendor finds an internal anomaly, notifying affected parties carries an internal deadline and an audit trail.
