coldsnap.py is a python-based snapshot-based ptrace-based fuzzer example. The purpose of this example is to test the performance of snapshot fuzzing entirely in python and to provide an educational example of a snapshot fuzzer. Coldsnap uses ptrace to control the program state for saving state and for guiding the fuzzer through ptrace-applied breakpoints. This example is not meant to be a production-ready fuzzer. Instead, this example should be used as educational material on how to put together a simple snapshot-based fuzzer with coverage guidance in python.
