It is a way to test for overall reliability as well as identify potential security bugs. The fuzzer we are using is AFL, a fuzzer that uses runtime guided techniques to create input for the tested program. From a high-level prespective AFL works as follows: -- Forks the fuzzed process -- Genereates a new test case based on a predefined input -- Feeds the fuzzed process with the test case through STDIN -- Monitors the execution and registers which paths are reachable + +* Forks the fuzzed process +* Genereates a new test case based on a predefined input +* Feeds the fuzzed process with the test case through STDIN +* Monitors the execution and registers which paths are reachable ![Alt text](fuzz/imgs/fuzz.png "AFL Fuzzing") -### Compile +Compile +------- + To start fuzzing this project with AFL you'll need to compile it with AFL.
