What is CTF and how does it work?
CTF stands for "Capture the Flag," which is a cybersecurity competition where participants solve technical challenges to find hidden strings of text known as "flags." These flags are intentionally hidden within vulnerable programs, websites, or systems. Participants work individually or in teams to retrieve as many flags as possible within a set time frame. CTFs typically follow two main formats: Jeopardy-style, where participants solve a series of independent challenges across categories like cryptography, web exploitation, and reverse engineering for points; and Attack-Defense, where teams must defend their own vulnerable systems while simultaneously attempting to exploit the systems of opposing teams to steal their flags. Beyond competition, CTFs are widely used as practical training grounds to apply theoretical cybersecurity knowledge in a controlled, legal environment.
