MozPeach is a fork ofPeach v2.7 by Mozilla Security. With support from our community and partnerships our goal is to continue to deliver Peach as an open source product with Python compatibility and new features.
Our focus is on usability, speed and fewer dependencies. We have also begun work on Python 3 support, replaced deprecated Python dependencies, switched the XML back-end, added a new configuration system, simplified code and much more.

Peach uses XML based "pits" as configuration files. There are two types of pits which we will briefly describe here.
Pit: Data Model
A data-model pit is an XML description of a specification and is required to parse any kind of input into an in-memory XML tree. Peach then uses that tree to generate fuzzed output.
Pit: Target
The target pit is used to define how the target process will get fuzzed, how it will be monitored for suspicious behavior and how to deal with results.
It is optional whether you place everything into one pit however not doing so will simplify working with multiple targets, different hosts and reusing pits. Following the data model/target pit practice will allow the reuse of data model pits across projects.
./peach.py -pit Pits/<component>/<format>/<name>.xml -target Pits/Targets/firefox.xml -run Browser
HINT: You can set related configuration values for both pits from the command-line by using the -macros switch.
./peach.py -pit Pits/<component>/<format>/<name>.xml -1 -debug| less -R
NOTE: This will show a very verbose output of the parsing process. To see only the results of the parsing process for each element you can add: "| grep Rating | less -R"
