A simple tool designed to help out with crash analysis during fuzz testing. It selectively ‘un-fuzzes’ portions of a fuzzed file that is known to cause a crash, re-launches the targeted application, and sees if it still crashes.

Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.

Getting started

Install on BlackArch with `pacman -S fuzzdiff` (or add the BlackArch repository to an existing Arch Linux install). See the official BlackArch tool listing linked above for details.
