What is AI Tool: Big Sleep?

A groundbreaking AI tool developed by Google that autonomously discovered a zero-day vulnerability in SQLite, a widely used open-source database engine, in November 2024. This marked the first instance of AI identifying an unknown exploitable memory-safety issue in real-world software. The vulnerability, a stack buffer underflow, was detected using advanced variant-analysis techniques, leading to a prompt patch by the SQLite development team. Big Sleep exemplifies the potential of AI to enhance cybersecurity by proactively identifying vulnerabilities before they can be exploited.
