Honggfuzz is a security-oriented, feedback-driven evolutionary fuzzer that uses software and hardware code coverage to discover bugs in binaries. It is multi-process and multi-threaded, supports persistent in-process fuzzing at up to 1M iterations/sec, and runs on Linux, macOS, Android, NetBSD, FreeBSD, and Windows (Cygwin).
Use cases
- fuzz a C/C++ binary to find memory corruption bugs
- find security vulnerabilities in a parser or file format library
- run coverage-guided fuzzing with hardware tracing on Intel CPUs
- fuzz an API in persistent mode for maximum throughput
- build a corpus automatically from an empty input directory
- detect hidden crashes and hijacked signals in a target process
- fuzz OpenSSL, Apache, or other open-source servers for CVEs
When to choose
- you need a fast, multi-core coverage-guided fuzzer for C/C++ targets
- you want hardware-based feedback via Intel BTS/PT
- you need persistent-mode fuzzing with very high iteration rates
- you want a fuzzer that can start from an empty corpus
- you need broad OS support including BSD and Android
When to avoid
- you fuzz JavaScript or managed-language code without a native harness
- you prefer a fuzzer with a rich web dashboard or cloud orchestration
- you need Windows support beyond Cygwin
- you want a fuzzer with extensive structured-input grammar support out of the box
