Introduction

I had a lot of fun spending this summer coding for radare. I learned so many things, and had an amazing experience overall. I am very grateful to my mentors, Xvilka, Pancake and Maijin, they were always present and closely followed me during the entire summer.

Introduction

The task of the project was about finding an obfuscated app on the play store, modifying it such that it would notify another app whenever it was opened.

I did not really have a quick way to check wheter an app on the play store was obfuscated or not, so I decided to choose an app that I knew for sure had at least some kind of obfuscation, and that app is Whatsapp Messenger.

The apk for "Whatsapp Messenger" I got is version 2.20.123, x86 architecture (because that's the architecture of the emulator I am currently running)
