Hey everybody!
Last time we released a bunch of challenges, we took it easy on you. Not this time. This week the challenges have point values between 250 and 500 point each, and are an even split between crypto and forensics. No foolin’!
For screenshots and descriptions of this week’s additions, see below.
Good luck and have fun!
