Hacktoria CTF - Writeup
Introduction
Here is my team M0DUL0's writeup for the Hacktoria CTF of June, Though my teammates Informant and gluppler were much more involved than me in this!
These are our answers as we have answered them. Due to the nature of publishing our answers via Google forms, not all of these are correct - for a full writeup of all the correct answers, it'd be best to look at Hacktoria's official writeup. This serves to document what we sent out!
Most GEOISNT questions and anything related to finding locations of things were solved via a combination of google and reverse image search and won't be going into detail explaining.
