侍 A One-Day Elite Hacking Tournament 一日決戦
Sheath your ignorance, unsheathe your skills. Samurai CTF spans six disciplines, one battlefield. Sharpen your blade and hold your ground — the gates open soon.
— Gates open in —
Infiltrate vulnerable web applications. SQL injection, XSS, CSRF, SSRF — the web is your battlefield.
Break ciphers, factor RSA keys, exploit weak entropy. Knowledge is the key that unlocks all locks.
Buffer overflows, ROP chains, heap exploits. Command memory itself as a samurai commands steel.
Disassemble compiled code. Understand what others tried to hide. No binary survives your blade.
Carve files, analyse memory dumps, recover deleted data. The evidence always leaves a trace.
Open-source intelligence. The greatest samurai gathers information before the battle begins.
