Project Description

Boofuzz is a fork of and the successor to the Sulley fuzzing framework. Besides numerous bug fixes, boofuzz aims for extensibility, with the eventual goal of being able to fuzz anything fuzzable.


Sulley has been the preeminent open source fuzzer for some time, but has fallen out of maintenance.


Like Sulley, boofuzz incorporates all the critical elements of a fuzzer:

  • Easy and quick data generation.
  • Instrumentation – AKA failure detection.
  • Target reset after failure.
  • Recording of test data.

Unlike Sulley, boofuzz also features:

  • Much easier install experience!
  • Support for arbitrary communications mediums.
  • Extensible instrumentation/failure detection.
  • Better recording of test data.
  • Far fewer bugs.

Sulley is affectionately named after the giant teal and purple creature from Monsters Inc. due to his fuzziness. Boofuzz is likewise named after the only creature known to have scared Sulley himself: Boo!

Boo from Monsters Inc


Boofuzz installs as a Python library used to build fuzzer scripts. See INSTALL.rst for step-by-step instructions.

Getting Started

No quickstart guide is available yet, but in the meantime you can use this Sulley FTP example as a baseline.


Pull requests are welcome, as boofuzz is actively maintained (at the time of this writing ;)).


If your question takes the form of “How do I… with boofuzz?” or “I got this error with boofuzz, why?”, consider posting your question on Stack Overflow. Make sure to use the fuzzing tag.

If you’ve found a bug, or have an idea/suggestion/request, file an issue here on GitHub.
