A community, not just a competition

What XSec CTF is, who it's for, and why we built it this way.

What is a CTF?

A Capture The Flag (CTF) is a hands-on cybersecurity competition. Each challenge hides a secret “flag” behind a puzzle — a vulnerable website, an encrypted message, a suspicious file, a hidden clue. Find the flag, submit it, score points, and climb the leaderboard.

Why participate?

Cybersecurity is easiest to learn by actually doing it. This event gives you real, hands-on practice across five real categories — Web, Cryptography, OSINT, Digital Forensics, and Steganography — in a safe, legal, and genuinely beginner-friendly environment.

Who can join?

Anyone, anywhere. This event is 100% online and open internationally — whether you've never touched a terminal or you already know your way around Burp Suite, there's a challenge here for you.
