2013 CTF Game

The following is a list of all of the challenges used for the 2013 CTF along with their description and link for convenience. Each of these challenges contain a README which well tell you how to stand up the challenge and the correct key to allow you to check yourself when you solve it.


Title Value Repository Description
Jarhead 200 2013-binary-200 “Knock, knock.” “Who’s there?” very long pause... "Java"
Era of Fantastic Colonies 200 2013-binary-200B You just downloaded the hit new real time strategy game, `Era of Fantastic Colonies.' It's now giving you trouble, asking for a CD key. Surely you purchased it, so that shouldn't be a problem. Can you get around the obnoxious DRM?
K-535 Yuriy Dolgorukiy 300 2013-binary-300 We've intercepted a submarine transmission from the Soviets. Only one authorization code disables the nuclear strike. Anything else and well... let's just say we're evacuating the entire eastern seaboard.

Das Milkshake 100 2013-crypto-100 Caeser's milkshake brings all the Legionnaires to the yard...
Le Chiffre Indechiffrable 200 2013-crypto-200 Dear Yvonne, I have sent this to you because I fear that our government is tracking me. Vive la Revolution!
Unbreakable 300 2013-crypto-300 Scientist announces unbreakable encryption! The cryptographic community is bewildered! In a press release, the scientist states that he can prove that his cryptographic method is theoretically sound.
German Intercepts 400 2013-crypto-400 The year is 1914. America is entrenched in World War One, and you've managed to get your hands on an intercepted message from the Germans. It's been heavily encrypted, but as America's finest cryptographer of the era, you feel up to the challenge. You know this cipher is the one the French call Ubchi, and that the same keyword has been applied twice. You don't know what the keyword it, however it shouldn't be any longer than 15 characters.
Modern Cryptography Standards 500 2013-crypto-500 The year is 1972, and as an official of the US government it's come to your attention that a new standard for classified information is needed in this modern day and age. In the past, cryptography has worked well, no ciphers currently exist that would be suitable for this task, however a new cipher has just been proposed by IBM and it's up to you to try to crack their message. You know that they used a weak keyword consisting of 4 pairs of 2 letters each (e.g. 'AeAeAeAe') as well as a weak encryption method, the electronic codebook. Since IBM's cipher relies on a certain number of rounds, you also know that they could be using anywhere from 10 to 50 rounds. Everyone's counting on you to give an answer on whether or not this cipher is a good fit for the government. Good Luck.
