This last weekend was the final DerbyCon. We’ll #TrevorForget. It was also an event filled with several quick and fun CTFs… and since I’ve been deficient in posting things lately, I figured I’d catch up by showing how to solve a whole pile of them. First up: the TrustedSec Challenge Coin! Attendees could get one of these by just showing up and asking for one, and there was a prize pack being awarded to anyone who could solve it. I was the fifth to do so, and figured others might want to know how to get to the final message.
