Understanding Capture the Flag (CTF)
Capture the Flag (CTF) is a cybersecurity competition where participants, individuals or teams, solve a series of challenges to “capture the flag,” typically a piece of text or data hidden within a challenge. These challenges can range from cryptography and web exploitation to reverse engineering and binary exploitation.
Think of a CTF as a real-world cybersecurity gym. It’s a place to test your skills, learn new techniques, and have fun while doing it.
