PAN LabyREnth CTF 2016: Windows Level 2

Write-up

There are three files for this challenge. babbysay.exe, AxInterop.WMPLib.dll, Interop.WMPLib.dll. Running the program reveals a keyboard. Keyboard

The program was written in .NET so I use ILSpy to take a peek a the program logic.

Solution

Some of the interesting code is here. Code

The code will do something if a certain sequence of keys are pressed.

The sequence is b16, w24, w25, w21. The sequence is repeated twice, and the key numbers start from zero.

I get the key and a funny little video. :) Flag
