Blahaj​CTF

Recommended for beginners who want to get their toes wet in cybersecurity! 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.

During the CTF, participants will face a smaller set of easier challenges that are more beginner-friendly.

The Training Division is open to secondary and tertiary students, and NSFs only. Undergraduate students may participate in the Open 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, but if you're eligible for NCO, you can still sign up for the workshop through your school!^*

The Competitive Division is open to secondary and tertiary students, and NSFs only. Undergraduate students may participate in the Open Division.

^*Internally, the workshop has a set quota of participants from NCO, and a set quota of participants from BlahajCTF Training Division. 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.

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.
