About BlahajCTF
A sharktastic Capture-the-Flag (CTF) competition, perfect for all skill levels! We'll have something for you, no matter where you stand: Training, Competitive, or Open Division!
Come as you are and leave with epic cybersecurity skills, new friends and most importantly: shark-filled memories!
Divisions
Training Division
Recommended for beginners who want to get their toes wet in cybersecurity! During the CTF, participants will face a smaller set of beginner-friendly challenges.
Up to 50 participants will be eligible for the NCO x BlahajCTF Training Workshop, where we'll cover the basics of CTFing and get you up to speed. Do note that registration for the workshop is separate from BlahajCTF.
Open to secondary/JC/Poly/ITE students, and NSFs only.
Competitive Division
Recommended for those who want to challenge themselves! Participants will face the full set of challenges curated by our challenge creators.
Participants in this category will not be eligible for the NCO x BlahajCTF Training Workshop.*
Open to secondary/JC/Poly/ITE students, and NSFs only.
*Registering for the Competitive Division will mean that you are only allowed to join the Training Workshop via NCO and not BlahajCTF, if you are eligible via NCO.
Open Division
For undergraduate students and other ineligible participants, you can still join in the fun via the Open Division, and even come down for the finals and collect your merch! Do note that there will be no prizes for the Open Division.
Usage of LLMs
The BlahajCTF team takes a strong stance against the use of LLMs and AI agents during the CTF. We believe that such tools take away the fun from CTFs and are detrimental for your learning. As BlahajCTF is catered to beginners, we want to protect the spirit of learning as much as we possibly can.
Please note that usage of such tools is banned for both qualifiers and finals for all divisions. If a team is found to be flouting this rule, the BlahajCTF team will not hesitate to disqualify the team from participating in current and future events, as well as notify other CTF organizers about such behaviour.
