TJCTF is a Capture the Flag (CTF) competition hosted by TJHSST's Computer Security Club. It is an online, jeopardy-style competition targeted at high schoolers interested in Computer Science and Cybersecurity. Participants may compete on a team of up to 5 people, and will solve problems in categories such as Binary Exploitation, Reverse Engineering, Web Exploitation, Forensics, and Cryptography in order to gain points. The eligible teams with the most points will win prizes at the end of the competition. Anyone is allowed to compete, but only high school teams in the United States are eligible for prizes.

TJCTF 2020 is NOT over yet. Please DO NOT post solutions or flags yet. Thanks for understanding!


vimMay 26, 2020, 11:43 p.m.

This CTF should be banned for lifetime, admins are RUDE, unresponsive, flags leaked, date shifted by one day, bad infrastructure. Server asking to answer capthca each time you access the platform. There were some CTF with no good quality but admins were there to support participants. This CTF is crappy from one hand and admins are crappy also in the other hand.
Please don't upload the scoreboard ! crappiest CTF ever seen !

Problem quality may not have been the greatest, but the quality of infrastructure and admin support largely made up for it. The flag leak was unavoidable - some malicious players decided to upload flags on the leaderboards and there was nothing the admins could od about it. Some players might have had a few problems because the admins were entirely US-based, but this wasn't an issue for us. Overall, the CTF was on the better-end in terms of quality and would definitely recommend participating if it happens again next year.

Agreed. While there were some outages, I otherwise thoroughly enjoyed the CTF, especially since it had plenty of challenges that I think were of suitable difficulty for me, a relative beginner, that weren't easy but weren't impossible either. Nice work, guys.


RazviMay 27, 2020, 6:44 a.m.

I agree with the last two comments. While it's true that there were some infrastructure problems and flags leaks, the overall experience was great for me. I enjoyed the challenges and I appreciate there was a really wide variety of them. Thanks to the organizers and see you all next time :)


CsEnoxMay 27, 2020, 6:57 p.m.

Even i agree with these negative comments !
