AI For Good; Google AI Blocks Zero-Day Exploit
In a milestone moment for cybersecurity, Google’s AI-powered defender “Big Sleep” has reportedly blocked a zero-day exploit targeting SQLite before threat actors could use it in the wild.
The Big Sleep Breakthrough
Big Sleep, developed by Google Project Zero and DeepMind, discovered a critical memory-corruption flaw in the widely used SQLite database engine. Tracked as CVE-2025-6965, this had not yet appeared in public scans but was known to attackers.
AI Acting Proactively
What makes this significant is that the AI acted proactively and alerted the vulnerability by Google Threat Intelligence that an exploit was imminent. Big Sleep pinpointed the vulnerability and triggered a preventive patch for it all before a breach occurred. Google claims this is the first timean AI agent has directly thwarted a real-world cyber threat.
Why This Matters
SQLite powers countless applications from mobile apps to embedded systems. A zero-day exploit in it could have had massive downstream consequences. Big Sleep’s intervention signals a leap from reactive cybersecurity to predictive, AI-powered defense.
What This Means for Defenders
AI is transforming cybersecurity by detecting threats at speed and scale, analyzing signals and code faster than humans to stop vulnerabilities before they’re weaponized. Google’s Big Sleep extends this protection beyond its own systems to widely used open-source components to scan and fortify. By combining traditional controls with AI-driven methods, Google is pioneering security as a hybrid defense that is both faster and more accurate.
Takeaway for Businesses
While the news is talking about all the bad and scary things that AI can or has done, this is a great change of pace to see AI working for us. Especially when many malicious people have only used it to work against us.
