LabyREnth 2017 CTF By Palo Alto

Challenge Archive site @ http://archive.labyrenth.com/

This was an approximately 6 weeks long reverse engineering centric CTF created by Palo Alto

It consists of 5 main tiers (Binary, Mobile, Docs, Threat, Programming).
Each tier has a set of 5 challenges where you have to clear each stage to proceed to the next.
After completing all 5 tiers, there is also a boss challenge.
It also has a Random tier which are hidden all over the challenge map

Do note all challenge zip files provided are password protected

  • Default pw is "labyrenth" unless otherwise stated

I've managed to complete 1 random challenge, the 5 main tiers and the Boss challenge.
Therefore, I will be uploading writeups for these challenges.
