boofuzz

boofuzz is a network protocol fuzzing framework written in Python, developed as the successor and modern fork of the Sulley fuzzing framework. It provides a flexible and extensible architecture for defining protocol grammars, generating mutated test cases, and monitoring target applications for crashes and anomalous behavior. Vulnerability researchers, security testers, and software QA teams use boofuzz to discover memory corruption bugs, parsing errors, and denial-of-service conditions in network services by sending malformed data that exercises edge cases in protocol implementations. The framework includes built-in process monitoring, crash detection and recording, test case logging, and a web interface for tracking fuzzing progress, making it a comprehensive solution for systematic protocol security testing.
