Many years ago Michal Zalewski created a source code based fuzzer that became the industry standard. When he left Google a few dedicated people picked it up and created a community version, afl++, that is actively developed with state-of-the art ideas coming from research and industry. In not even two years afl++ has become the most effective fuzzer (based on Google's Fuzzbench benchmarking), is actively developed and maintained and was just integrated into Google's oss-fuzz. It is now part of the critical infrastructure to identify security vulnerabilities in source code. Join us to develop on the next evolution that we have planned - based on the Rust development language.
