XSEC CTF
A capture-the-flag arena built and run by XSec Solutions. Solve the challenges, capture the flags, and climb the board. Open to students and anyone ready to test their skills against the clock.
Six categories, one scoreboard
Every challenge drops a flag. Find it, submit it, score it. Points scale with difficulty, so the hard ones are worth the grind.
Web Exploitation
Injection, auth bypass, broken logic — pull flags out of vulnerable apps.
Binary Exploitation
Overflow it, leak it, pop a shell. Memory corruption against real binaries.
Cryptography
Weak ciphers, bad keys, broken protocols. Recover the plaintext.
Forensics
Dig through captures, disk images, and files for what's hidden inside.
Reverse Engineering
Take the program apart and understand what it really does.
OSINT
Open sources, real trails. Find what people leave behind in public.
