This was the first year our capture-the-flag event, UMass CTF 2021 , was open to the public. The competition started Friday, March 26th at 18:00 EDT, and ended Sunday, March 8th at the same time. By the end of the competition, we had 1991 registered users , belonging to 1160 registered teams . No teams were tied, we had just one unsolved challenge, and each of the "harder" challenges had just one or two solves.
