Here's what they know: the target company sends "Weekly Report" emails to its employees. The reports usually link to an internal file server for download and viewing. For reasons unknown, one employee registered his personal email on the list and has a tendency to use this email at work. His email is and from what we can tell, he's not the most tech savvy and will probably open anything you send him if it looks like a Weekly Report. The rival company knows that the primary designer for the target company is named Dooku and they want you to extract as much as you can from his system. Happy Hunting! Hint: Hint2: Flag is the password for Grievous!

Holy Krabby Patty, Mermaid Man! 50 2015-crypto-50 Oh no! Mermaid Man has left his belt at the Krusty Krab. You fully intend to return the belt to him, but first you want to enjoy a Ceaser Salad.

Coffee Shop Routers 100 2015-crypto-100a While at a local coffee shop, enjoying your morning cup of coffee and daily hacking practice, you manage to gain access to the shop's router and begin to capture network data. You have intercepted an "image" that looks like it may contain some interesting information based on the other requests and responses coming from that IP. Unfortunately, the image has been corrupted during transmission and you now need to unscramble it. Note: Key is 10 hex digits.
Mystery Twins 100 2015-crypto-100b While wondering through the woods next to the Mystery Shack, you found a suspicious "piece of paper". You're sure it's a part of a torn page from the journal you found, but it's written in some sort of strange alphabet.
Crazy Kids with their Hippity Hoppity Music 300 2015-crypto-300a Your friend, Bin, has given you a "sound file" of this hip new band he swears is going to make it big because they've created a whole new genre.

Message from the Doctor 300 2015-crypto-300c The Doctor has paid you a visit and helped you get rid of a stubborn Isolus. Before he left, he gave you a "note", but it seems to be written in a strange language. Maybe you can decode the message to see what the Doctor wants to tell you.

The Butterfly Effect 200 2015-traditional-200 Your younger sister has gotten a hold of your computer and downloaded a bunch of "images of butterflies".

Who is the Real Slim Shady? 250 2015-traditional-250b We paid someone to improve our Slim Shady fan club website, endorsed by Shady himself. I guess he didn't like Slim Shady though, because he hacked into our "emails" and made our website worse. We would like you to fix it. Slim Shady should have sent me an email with the password to go and reset the site, but there are so many in my email, I don't know which to use! Here are all the emails I have theoretically gotten from Slim. Oh, and it probably won't be much use, but here's what's left of our website, in case it helps you design the new [website". THANK YOU! --The Slim Shady Fan Club
