Google CEO Sundar Pichai revealed that its AI tool Big Sleep successfully stopped a cyberattack before it began — marking what may be the first time AI has ever independently prevented a cyber threat. Developed by Google DeepMind and Project Zero, Big Sleep detects hidden software flaws and recently blocked an exploit involving a vulnerability in SQLite. This breakthrough signals a major shift in cybersecurity, moving from reactive defense to proactive prevention. While full details remain undisclosed, Google plans to expand Big Sleep’s use across its services, potentially setting a new standard for AI-driven digital protection worldwide.
