• The Stargate Complex

    Hi All,

    I just ported one of my old CTF challenge to my BBS. It is absolutely suited for BBS integration since it was an all ASCII track. I've basically created a MUD-like environment called "The StarGate Complex" where the participants had to connect and explore to gain points in the CTF.

    For those unfamiliar with CTF, these are security competitions where security researchers (or hackers) try to complete technical challenges to obtain flags (proof they succeeded) and submit they to a scoreboard. At the end of the event, the team with the more points wins...

    There is multiple number of puzzles and challenges. One can solve them by hand at the beginning while learning the environment but they had to use that knowledge to build an automated learning script to automatically read the puzzle and provide the answers. Some very basic machine learning in a
    nutshell.

    The track was chosen as best challenge of the year and had excellent feedback. Only 1 team out of the 70 managed to complete it during the CTF.

    The track in numbers:

    * English dictionary containing 87047 english words
    * Acronym dictionary containing 3361 acronyms
    * 4498 networks services names and mapping
    * 93 trivia questions
    * 25 different hashing algorithms
    * 6 Different encoders
    * 76 in-game secret items
    * 9 black-market items (you could purchase from the scoreboard)
    * 5 possible flags per track
    * 29 addressable StarGate addresses (using the chevrons you unlocked)
    * 7 tracks to complete to activate the StarGate and access the end-game

    The puzzle engine selected from all these data sources to create unique and ramdom puzzles, the participant had to understand the puzzle and answer it correctly because the more you progressed, the more fatal a mistake was.
