Overview

Google's continuous fuzzing infrastructure (OSS-Fuzz + ClusterFuzz) has found over 10,000 bugs in 1,000+ open source projects, including critical security vulnerabilities like Heartbleed-class bugs. This technique turns fuzzing from a one-time activity into a continuous quality gate.

Core Philosophy

"Fuzzing should be continuous, not a one-time event."

"Every bug found by fuzzing is a bug not found by attackers."

Fuzzing is most effective when it runs continuously against the latest code, with automatic bug reporting and regression tracking.
