Fuzzungus: Advanced Network Protocol Fuzzing
Fuzzungus is a fork of the Boofuzz framework, itself a fork and the successor of to the venerable Sulley fuzzing framework. Fuzzungus was created as part of a Safran Electronics & Defense project.
Why?
Boofuzz was lacking a lot of the features needed to fuzz aerospace protocols. By forking Boofuzz, the goal was to be able to easily add them without having to undergo the code review of Boofuzz maintainers, to speed up the development.
This project won’t be maintained much further, excepted some minor fixes and updates by the Safran Electronics & Defense Red Team, so feel free to fork it and make it your own, or, if you happen to be one of the maintainers of Boofuzz, to integrate the changes back into the main project. We would be happy to help you with that.
Features
Fuzzungus incorporates all the elements from Boofuzz :
Easy and quick data generation.
Instrumentation – AKA failure detection.
Target reset after failure.
Recording of test data.
Much easier install experience!
Support for arbitrary communications mediums.
Built-in support for serial fuzzing, ethernet- and IP-layer, UDP broadcast.
Better recording of test data – consistent, thorough, clear.
Test result CSV export.
Extensible instrumentation/failure detection.
Far fewer bugs.
Fuzzungus also includes a number of new features:
Refactored codebase of a number of modules to make it easier to understand and extend.
Better configuration system
Three generation modes (library, random mutation, and random generation)
New primitives for data generation
Great restart and continue on failure
Timeout detection
Full protocol sessions supports (multiple acks, fragmentation…)
In the continuity of Boofuzz, Fuzzungus is also named after a character from Monsters Inc. This time, it’s Fungus, the assistant of the villain Randall Boggs, just because it’s a funny name.

Installation
Boofuzz was installable as a Python library through pip, but it isn’t the case of Fuzzungus, that has to be installed through the source code. See Installing Fuzzungus for advanced and detailed instructions.
