Morty’s new tool is an intermediate level Android application CTF challenge. The basic aim of this CTF challenge is to learn the dynamic transformation in the code at run time, reverse engineering of native libraries and much more.

It will give an atmosphere of real time scenarios which will teach us the working of an application, its process and data flow.

Let’s take a minute to thank Moksh for creating this challenge. If someone wants to try and solve the challenge before going through the walkthrough, the link for the CTF can be found [here] and the application can be downloaded from [here].
