IAANSEC - BrickRoll (Official Write Up)

Witness the Rick Astley Experience NOW!

Developed by L0WK3Y

Intro

"Odd, I clicked on the Rick Astley Simulator icon but it didn't.... Wait...OH MY GOD MY EARS!!!"

In this IAANSEC CTF you will be tasked with analyzing the Rick Astley Experience binary. This room will test your cryptography, stenography and malware analysis skills. Have fun and good luck!

(Quick note, majority of flags are Rick Roll lyrics and are separated with an underscore "_". Lastly I HIGHLY recommend using Procmon to solve this CTF)
