What is Cracknet? As a part of the SecTalks May CTF I built a .Net reverse engineering challenge, Cracknet. I’ve since made this available on Github, here. Although it’s possible to complete this challenge by bypassing a JMP instruction in assembly the intention of this challenge was to introduce participants to decompiling .Net applications by patching the application. Exploring CrackNet functionality When you first open CrackNet you’re presented with the following:

CrikeyCon 2017 - Fast Math Writeup
