Ethernaut CTF walk through

This is a walk through of the Ethernaut capture-the-flag competition where each challenge was an ethereum smart contract you had to break.

I did this at 2am in a hotel room in Romania and ended up not finishing the last challenge because I took too long and didn’t want to re-record that part. Basically what I was missing in my malicious contract: a function to withdraw tokens from the victim contract (it would have work since I had a huge amount of token via the attack). I figured I should still upload that as it might be useful to someone.
