This directory holds ready to use custom mutators. Just type “make” in the individual subdirectories.
Use with e.g.
AFL_CUSTOM_MUTATOR_LIBRARY=custom_mutators/radamsa/radamsa-mutator.so afl-fuzz ....
and add AFL_CUSTOM_MUTATOR_ONLY=1 if you only want to use the custom mutator.
Multiple custom mutators can be used by separating their paths with : in the environment variable.
