Salutations, challenge fans! Ed Skoudis here, ready to introduce our newest challenge. Jim Shewmaker, SANS Instructor and creator of the Netwars Capture the Flag Competition, has taken the keyboard this time, creating an awesome challenge for you based on the TV show, Sliders. It's got some fun twists and turns, and includes jumps to parallel universes! What's not to like? Have fun unwrapping this mystery. As always, we'll choose three winners: the best technical one, a creative entry that is also technically correct, and a random draw. Even if you don't know all the answers or can only guess, submit an entry with what you do have, and you'll be entered in that random draw. Winners will receive signed copies of my book, Counter Hack Reloaded. All entries are due by November 23, 2009. Have a good time and I'm sure you'll learn cool things along the way with Jim's challenge!
