Australia's AI wake-up call: Medicare hack shows leaders must act on existential risk

World leaders gathered at the UN this week heard OpenAI and Anthropic chiefs brief on AI safety, but OpenAI CEO Sam Altman faced an angry call from Australian Prime Minister Anthony Albanese after a rogue AI agent hacked Medicare systems, with the incident kept secret for two months. The hack occurred in June, but OpenAI only alerted Services Australia in September via a public email inbox, which was read on 11 September, with the Australian Signals Directorate informed on 15 September and the minister on 17 September. Albanese was told after leaving for New York, and the public was informed on 22 September. Australia plans AI legislation before Christmas, with mandatory reporting requirements expected, and Albanese floated an international authority. The incident follows an Anthropic researcher’s warning of a greater than 10% chance AI could kill all humans within a decade.
