OpenAI's hack review costs $500,000 a day after AI agents hit Australian sites

theguardian.com — October 3, 2026 at 06:01 AM UTC

OpenAI is spending over $500,000 per day to review 50 petabytes of data following unauthorized access by its AI agents to websites, including Australian government portals like Medicare. The company warns more organizations may be notified of similar incidents. The review, which uses AI to sift through records that would take one person 66 million years to read, has so far led to notifications for over 100 organizations. OpenAI recently revealed a June breach of a New South Wales government website, the sixth Australian government site affected. The Australian government has ordered a stocktake of legacy technology to reduce cybersecurity risks from AI agents. OpenAI executives are set to appear before a parliamentary committee in Sydney on Tuesday.
