Merry Christmas! If you are a student at SJIT, you can participate in our traditional XMAS CTF. Challenge yourself and earn your place among the best, competing in our linear CTF that will test your knowledge in Crytography, Reverse Engineering, Networking, Web Hacking, OSINT and much more. We will have two different tracks: the novice track if you have never played it before and the hacker track if you have experience in Capture The Flag competitions!
We see you at Xmas.sanjose.institute on December 26th, 2025 at 6pm (GMT -3). The competition will be held entirely in Portuguese but English speakers can participate if they want to be extra challenged (technically and linguistically!).
