Tools used: exeinfo, Reflector
Codes & Binaries: https://github.com/jmprsp/labyrenth/tree/master/Window-Challenge-2
Description: This challenge is written in C#. Decompiling it is trival using tools like Reflector. You may find a copy of the decompiled source code in github.
On executing the challenge, you will see the following… looks like we need to key in a certain sequence before we can get the flag.
Decompiling the challenge using reflector is easy. The key_click function looks suspicious with all the funny characters…
Being lazy… i shall just copy paste most of the codes here into another c# project (removing the if else) and writing the thangs variable to a file. Compile & run XDDDD
Wow we got the flag just like this…
