Mountain View, CA — August 5, 2025 — Google has announced a significant milestone in cybersecurity through its AI-driven bug-hunting tool, named ‘Big Sleep’. According to the company, Big Sleep has autonomously discovered and validated 20 security vulnerabilities within open-source software libraries, marking a major advancement in the use of artificial intelligence for software security.
Big Sleep operates by analyzing open-source codebases to detect hidden bugs that could potentially be exploited by malicious actors. Unlike traditional methods relying heavily on human auditors, this AI-powered system leverages machine learning models trained to identify subtle coding flaws and security weaknesses with high accuracy.
Heather Adkins, Vice President of Security at Google, highlighted the significance of these findings in a recent statement: “The discoveries made by Big Sleep demonstrate how AI can augment existing security protocols and scale vulnerability detection across expansive code repositories that are otherwise difficult to thoroughly audit manually.” These 20 newly reported vulnerabilities have since been responsibly disclosed and addressed by the respective open-source communities, thanks to Google’s coordinated efforts.
The development of Big Sleep is part of Google’s broader strategy to integrate AI technologies into cybersecurity defenses, improving rapid detection of threats and reducing the window of exposure for critical systems globally. Open-source software, widely used across industries, has increasingly become a target for attackers; thus, tools like Big Sleep offer promising promise to proactively safeguard codebases against exploitation.
Industry experts have welcomed Google’s advancement. Cybersecurity analyst Laura Reynolds noted, “Automating vulnerability discovery using AI not only accelerates patch development but also raises the baseline security hygiene among countless projects relying on open-source components.” With Big Sleep’s success, Google is expected to continue refining its AI models to cover a wider variety of software ecosystems and languages.
Google’s CEO Sundar Pichai has also emphasized the company’s commitment to embedding AI across its product and security stack, envisioning AI-powered tools as essential for the future of internet safety.
This development comes amid increasing challenges in managing software security at scale, highlighting the potential for AI as a force multiplier in protecting digital infrastructure.
