I recently participated with the CTF team Norse Code representing Hacking for Soju in the DEFCON 29 CTF qualifiers. There was a web challenge, so I went full speed ahead to solve it. Overall the challenge is fairly straightforward and not too difficult, but I decided to do a write-up on it to demonstrate one way that you are able to work through obfuscated JavaScript.
The challenge begins with a website link and a Chrome browser extension that you can download.

Brett, Jon, and I teamed up with Council of 9 and won this years badge challenge after having great success in the DEFCON 22 Badge Challenge. Over the last year we have studied a huge number of cryptographic methods and ancient languages to prepare for this. We also released our own crypto-challenge website for the community to follow along and have fun challenging themselves. With our new knowledge and a great team in tow we headed out to DEFCON.
Here is the entire adventure as we experienced it with all of the puzzles, their solutions, and the steps to solve them. Understand that this document contains MASSIVE spoilers so if you do not want to ruin it for yourself please stop reading now.
