About

American fuzzy lop is a program for fuzzing inputs. It is very sophisticated and can be instrumented with a binary to do very targeted fuzzing.

Installing

Get the latest version, and run make to make it:

$ wget http://lcamtuf.coredump.cx/afl/releases/afl-latest.tgz 
$ tar -xvf afl-latest.tgz cd afl-latest.tgz
$ cd afl-*
$ make 
$ make install

Success!

Programs that can be fuzzed are those that take input files, usually binary files or unusual formats. (Think mp3, multimedia, images, etc.)
