Module mutators

Help

Expand description

Mutators mutate input during fuzzing.

These can be used standalone or in combination with other mutators to explore the input space more effectively. You can read more about mutators in the libAFL book

Modules§

encoded_mutations: Mutations for EncodedInputs
gramatron: GramatronRandomMutator is a random mutator using grammar automatons to perform grammar-aware fuzzing.
grimoire: Grimoire is the rewritten grimoire mutator in rust. See the original repo Grimoire for more details.
hash: A wrapper around a Mutator that ensures an input really changed MutationResult::Mutated by hashing pre- and post-mutation
havoc_mutations: crate::mutators::Mutator collection equivalent to AFL++’s havoc mutations
list: Mutator definitions for ListInputs. See crate::inputs::list for details.
lua: This module implements the LuaMutator, where each mutation drops into a Lua VM to mutate bytes in a target-specific way.
mapping: Allowing mixing and matching between Mutator and crate::inputs::Input types.
mopt_mutator: The MOpt mutation scheduler used in AFL++.
multi: Mutator definitions for MultipartInputs. See crate::inputs::multi for details.
mutations: A wide variety of mutations used during fuzzing.
nautilus: Mutators for the Nautilus grammmar fuzzer See https://www.ndss-symposium.org/ndss-paper/nautilus-fishing-for-deep-bugs-with-grammars/
numeric: Mutators for integer-style inputs
scheduled: The ScheduledMutator schedules multiple mutations internally.
token_mutations: Tokens are what AFL calls extras or dictionaries. They may be inserted as part of mutations during fuzzing.
tuneable: An extension to the ScheduledMutator which schedules multiple mutations internally.
unicode: Mutators for preserving unicode string categories, which may be useful for certain targets which are primarily string-oriented.

Structs§

BoolInvertMutator: Mutator that inverts a boolean value.
MutationId: The index of a mutation in the mutations tuple
NopMutator: Mutator that does nothing, used for testing.

Enums§

MutationResult: Result of the mutation.
