The third day of iCTF opened amidst heavy competition.
A total of 48 teams have scored points, which includes 16 high school and 25 undergraduate teams. Players compete to solve a variety of challenges, with challenges ranging from hacking websites, fooling AI agents, reverse-engineering models, and fuzzy geographic feature search. High school players are currently hacking on 14 challenges, and undergraduate players are hacking on 13. Every challenge is solved by at least one team.
The first 48 hours of play were intense and fast-paced. 10 high school teams tied for first place (by points) at the end of day two. On day three, this has narrowed to a 5-way tie. High school team we lost was the first to solve the challenge "MysteriousModel," beating team Ignore All Previous Instructions by a mere 30 seconds. Meanwhile, undergraduates are hard at work solving some very difficult challenges: "LinearLabyrinth" has a mere two solves; any additional solves would place a team in contention with first place.
Several more challenges will be released over the next few days, all but ensuring a tough fight for the top place. For both high school and undergraduate players, plenty of opportunities remain to score points and climb to the top of the ranking. This is still anyone's game!
