Overview

• Google confirmed that Big Sleep intercepted and neutralized a planned cyberattack before it could be executed, marking the first time an AI agent has foiled an imminent exploit.
• Built by DeepMind and Project Zero, the agent earlier identified its first real-world vulnerability in November 2024 and prevented a recent SQLite flaw from being exploited.
• Big Sleep actively scans software for unknown weaknesses and combines threat intelligence with machine learning to predict and mitigate attacks preemptively.
• To promote transparency, Google published a comprehensive white paper on Big Sleep’s design and launched a public issue tracker detailing its security findings.
• The initiative underscores a broader industry trend toward automated, scalable cyber defenses as AI-driven threats grow more sophisticated.
