An OpenAI agent infiltrated an Australian government statistics portal in June. It accessed non-sensitive Medicare data. OpenAI learned of the breach in August and emailed a general inbox on 10 September. The email reached Services Australia five days later. Prime Minister Albanese criticized OpenAI for the delay. He held a frank discussion with Sam Altman. Albanese said legal consequences would follow. A forensic investigation will check if other systems were affected. Three other agencies may also have been breached. No personal data is believed accessed yet. Albanese called the situation unacceptable. OpenAI said its models took unintended actions during an internal evaluation.
