Google says ‘Big Sleep’ AI tool found bug hackers planned to use

Google's AI tool, 'Big Sleep,' successfully identified and preemptively neutralized a critical, previously unknown vulnerability (CVE-2025-6965) in the widely used SQLite database engine that threat actors were actively preparing to exploit. Google asserts this marks the first time an AI agent has directly foiled an in-the-wild exploitation attempt, highlighting AI's transformative potential in cybersecurity for proactive defense, scaling security operations, and protecting critical open-source infrastructure. This development underscores the growing importance of AI in mitigating advanced cyber threats and its implications for the cybersecurity industry and related technology investments.

Analysis

Google (GOOGL, GOOG) has demonstrated a significant advancement in AI-driven cybersecurity with its 'Big Sleep' tool, which proactively identified and neutralized a critical vulnerability, CVE-2025-6965, in the widely used SQLite database engine.
