Thanks, it does take a lot of thought and work to create the challenges, but I really enjoy it. I've certainly learned a lot in the process of how to create the challenges. A few of them I have thought about on and off for a few weeks before actually creating them. I create them using Python scripts then I solve them using Python also just to check that the challenge is created properly.
The main challenge in designing challenges is to make them interesting / challenging / maybe difficult without making them impossible. If you look at my forensics challenges I am trying to make a spectrum of challenges from easy to difficult... this challenge really is the result of what I learned on most of my previous jpeg / forensics challenges. https://ctflearn.com/challenge/by/kcbowhunter Some challenges that I created I thought would be difficult but ended up being easy... so I learned from that and created some challenges (like this one) that take a little more thought and examining the raw data in the jpeg as opposed to relying on tools to help find the solution.
