Droidefence – Advance Android Malware Analysis Framework

DroidDefence - Advance Android Malware Analysis Framework xploitlab

Android phone is still vulnerable to exploit, if we compare between IOS and Android for security IOS will be the winner, because in Android device attacker still can exploit with malicious applications. With Droidefence you can analyze a malware in your android.

What Droidefense is

Droidefense (originally named atom: analysis through observation machine)* is the codename for android apps/malware analysis/reversing tool. It was built focused on security issues and tricks that malware researcher have on they every day work. For those situations on where the malware has anti-analysis routines, Droidefense attemps to bypass them in order to get to the code and ‘bad boy’ routine. Sometimes those techniques can be virtual machine detection, emulator detection, self certificate checking, pipes detection. tracer pid check, and so on.

Droidefense uses an innovative idea in where the code is not decompiled rather than viewed. This allow us to get the global view of the execution workflow of the code with a 100% accuracy on gathered information. With this situation, Droidefense generates a fancy html report with the results for an easy understanding.
