CTF Information

Some info about CTFs...

  • What is a CTF?

    Well, a CTF (Capture the Flag) is a cybersecurity competition that focuses on a variety of topics. This includes Web Exploitation, Binary Exploitation, Forensics, Cryptography, Reversing and so much more. CTFs test you on these skills by providing you with fun and interactive challenges, where the goal is to capture a flag. A flag looks very similar to flag{hi_i_am_a_flag}. Here are some great links to help you understand what a ctf is:

  • HALPPPPPP I've never done a CTF before?!?!?!?!?!

    Woah...Woah...Woah...don't worry. This CTF will test people from all difficulty ranges. We want to be as inclusive as possible with how hard our challenges are. This means there will be a plethora of problems that a geared to those who start CTFs for the first time, and there will be just as many for those who are regulars. We want our CTF to boost CTF morale in general. This means those who are long-time competitors and those who have made this CTF their first CTF, should really enjoy the competition. This does not mean...all problems will be easy :p

Our CTF...


Here are some common questions we would like to answer about our CTF and CTFs in general.

  • Divisions:

    We will have two divisions Highschool and Open/College we do allow those in the Highschool division to switch to the Open/College division if they want. The criteria for the Highschool division is that you must be in the range of K-12. We do allow upcoming college freshmen to compete as Highschoolers since we consider that as still 12th grade.

    Better put:

    -->‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏High school division is for US-based high school seniors (and younger)

    -->‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ Open/College is well...open to all!

  • Referral Contest:

    We are introducing a referral contest which is a new way of advertising that we (as a team) have not seen in any CTFs so far. Every person who registers gets a token that is unique to them. They can then refer other people to the CTF by giving them their token and asking them to use it during registration. By doing this, that person receives another referral point. At the end (after the competition is over) the team who has referred the most teams wins a prize as well. This prize is TBD since it depends slightly on the number of referrals of the top team.

    Please note, we do NOT appreciate anyone spamming our server for referral points. We will periodically check those who are in first place on the contests and see if the teams they referred are valid. If we have enough evidence to conclude that you are spamming, we WILL disqualify you from the referral contest. Other than that...have fun getting more people!
