Automated native Android fuzzing

Fuzz testing is a great way to find exploitable bugs or bugs in system utilities. It allows auditors to gauge the effectiveness of file handlers and any other application against malformed and possibly malicious input, and helps determine whether there are any easily exploitable entry points on a system. It's also a great way to automate security testing.

Android is no different from any other system and has a myriad of interesting fuzz targets. The attack surface of an Android device doesn't stop at the Java application layer; in fact, root exploits are sometimes based on a native executable or system utility that doesn't properly handle any given input or respond in a secure way to certain situations. Fuzzing is a great way to find these situations and possible root exploits on an Android device.

What I'm going to cover here is how to port a fuzz test generator called Radamsa to the Android platform, and also install some utilities that will help you to...
