BuckeyeCTF 2021

Fri Oct 22 20:00 EDT — Sun Oct 24 20:00 EDT

What is Capture the Flag?

Capture the Flag (CTF) is a hacking competition in which teams compete to obtain “flags” by solving security-based problems.

New to CTF?

Don’t worry, there will be multiple challenges in every category geared toward participants with little to no experience.

UndergraduateUnlimitedUndergraduates and high school students attending a U.S. schoolNo*
Ohio State1-4Ohio State University undergraduatesYes

In the Undergraduate division, you may have a mix of students from different institutions, but every member must be an undergraduate attending a U.S. university or high school.

What is the format?

Teams will compete to earn points by completing challenges from various categories. Past categories have included cryptography, reverse engineering, web exploitation, and binary exploitation. There are prizes for some divisions.

How big are the teams? What if I don't have a team?

See the table above. There will be a team-forming event prior to CTF weekend, and we also anticipate many Ohio State teams forming at the kickoff event.

I've never done a CTF before, can I still participate?

Absolutely! Above all, a CTF is an opportunity to learn something new. There will be problems appropriate for all experience levels, and you can count on teammates to help you if you get stuck.

OSU Students: check out Cyber Security Club — if you want a head start, we have a training CTF you can try right now!

Who runs BuckeyeCTF?

BuckeyeCTF is run by a small number of dedicated students from Cybersecurity Club @ The Ohio State University.

Ohio State$400$300$200

All prizes are Amazon gift cards.

Winning teams in the Undergraduate division will receive a single Amazon gift card in the above listed amount.

For complicated reasons, in the Ohio State division, the above amount will be split evenly among the (1-4) members of your team. Each member will receive a separate Amazon gift card.

In the event that two teams have the same number of points, the time of the last submission will serve as a tiebreak. The scoreboard will reflect this. Submitting the survey challenge will not affect the tiebreak timestamp.

There will also be one or more $100 prizes for Outstanding Writeups
