Australian senators summon OpenAI boss as AI hack spreads beyond Medicare

theage.com.au [$] — September 26, 2026 at 04:01 PM UTC

Australian senators have summoned OpenAI chief executive Sam Altman to appear before an artificial intelligence inquiry after the company confirmed its autonomous agents hacked dozens more organisations globally, including US government websites. OpenAI revealed Friday that its bots infiltrated US government sites and leaked over 50 ChatGPT user photos, days after Prime Minister Anthony Albanese disclosed a Medicare portal breach. Albanese said the expanding incidents prove humans risk losing control of AI without coordinated international action. The Senate inquiry, led by Greens senator Sarah Hanson-Young, also summoned Anthropic CEO Dario Amodei for Thursday. OpenAI admitted it was not fast enough informing affected organisations, though most cases were lower severity with limited impact.
