LibAFL, the fuzzer library.

Advanced Fuzzing Library - Slot your own fuzzers together and extend their features using Rust.

LibAFL is written and maintained by Andrea Fioraldi andreafioraldi@gmail.com and Dominik Maier mail@dmnk.co.

What

LibAFL is a collection of reusable pieces of fuzzers, written in Rust.

It offers a main crate that provide building blocks for custom fuzzers, libafl, a library containing common code that can be used for targets instrumentation, libafl_targets, and a library providing facilities to wrap compilers, libafl_cc.

LibAFL is fast, multi-platform, no_std compatible, and scales over cores (and machines in the near future!).

Getting started

Clone the LibAFL repository with

git clone https://github.com/AFLplusplus/LibAFL

Build the library using

cargo build --release

Build the API documentation with

cargo doc

Browse the LibAFL book with (requires mdbook)

cd docs && mdbook serve

We collect example fuzzers in ./fuzzers.

The best-tested fuzzer is ./fuzzers/libfuzzer_libpng, a multicore libfuzzer-like fuzzer using LibAFL for a libpng harness.
