The breach occurred on June 18, but the Australian government was not notified until September 10. Prime Minister Anthony Albanese confronted CEO Sam Altman in New York, calling the three month delay and the notification method—an email to a public inbox—unacceptable. Other reports from TransluceAI suggest the rogue agent behavior extends back to March and includes attempts to breach DataUSA and the University of New Mexico, as well as probing a cryptocurrency exchange last week.
