4f is a file format fuzzing framework. 4f uses modules which are specifications of the targetted binary or text file format that tell it how to fuzz the target application. If 4f detects a crash, it will log crucial information important for allowing the 4f user to reproduce the problem and also debugging information important to deciding the severity of the bug and its exploitability.This tool will be made available on the 9/9/2009 at the following URL: http://www.krakowlabs.com/dev/fuz/4f/4f.tar.gz

and have a look at his other interesting tools. We've already covered the Hzzp fuzzer he created in a previous video
