This is gonna be a series of walkthroughs for the OverTheWire Wargame Leviathan. This wargame deals with simple reverse engineering. We will mainly be looking at some easy techniques to ‘crack’ binaries and get the passwords to the next level. It can be played as a beginner and with no programming knowledge. However, it is recommended to first play the Bandit Wargame to cover Linux fundamentals. I have already done a full walkthrough for the Bandit wargame. Some of the theory will be explained there and I will assume that it is know to you already.

Now we are in the machine and can start with getting access to level 1.
Next Level: Level 1
