Learn offensive and defensive security with guides, CTF writeups, quizzes, and practice labs.
Structured progression from networking basics through offensive and defensive security, with 61 checkpoint quizzes along the way.
Phase 0: Lab Setup →Guides to Nmap, Burp Suite, Metasploit, Hashcat, and other security tools.
Read guides →Command references for security tools and common tasks.
View sheets →HackTheBox walkthroughs with interactive terminal replays.
Read writeups →14 guided scenarios plus a free-exploration sandbox with 3 target machines, 100+ commands, and full filesystem simulation. Type real commands, see realistic output.
Start practicing →Learn cryptography by breaking it. 15 cipher visualizations plus hash identifier, generator, cracking guide, rainbow tables, and collision explorer. Encrypt, decrypt, and crack.
