Intel stock extends gains after report of possible U.S. government stake
Investing.com -- Google (NASDAQ:GOOGL)’s AI cybersecurity agent named Big Sleep has successfully detected and prevented an imminent security exploit, according to CEO Sundar Pichai.
The AI agent discovered an SQLite vulnerability (CVE-2025-6965) that was known only to threat actors and at risk of being exploited. Google believes this marks the first time an AI agent has directly prevented a vulnerability exploitation attempt in the wild.
Developed by Google DeepMind and Google Project Zero, Big Sleep actively searches for unknown security vulnerabilities in software. Since finding its first real-world security vulnerability in November 2024, the agent has discovered multiple vulnerabilities, exceeding the company’s expectations.
Big Sleep is also being deployed to improve security for widely used open-source projects, which Google says will help ensure faster and more effective security across the internet.
Google announced additional AI security capabilities coming this summer. The company is extending Timesketch, its open-source digital forensics platform, with AI capabilities powered by Sec-Gemini to accelerate incident response. Google will demonstrate this technology at Black Hat USA.
The company will also showcase FACADE (Fast and Accurate Contextual Anomaly Detection), an AI-based system that has been performing insider threat detection at Google since 2018. At DEF CON 33, Google is partnering with Airbus for a Capture the Flag event to demonstrate how AI can enhance cybersecurity professionals’ capabilities.
Google is donating data from its Secure AI Framework to the Coalition for Secure AI to accelerate work on agentic AI, cyber defense, and software supply chain security. Additionally, the final round of Google’s two-year AI Cyber Challenge with DARPA will conclude next month at DEF CON 33.
