Hello! Welcome to CTF Club (also known as the Based CTFers)! Our mission is to enhance offensive cybersecurity tactics through the world of competitive cybersecurity.

Jeopardy CTF competitions help you sharpen your cybersecurity skills by solving challenges to capture "flags" and earn points in a fun, gamified environment. All levels of experience from complete beginner to expert are welcome to drop in anytime! We'd love to have you come do CTFs with us!

Stay up to date with the #based-ctfers channel in the Computer Club Discord for the latest updates, and react to our group's role in the #info channel to get the role for pings!
