Learn offensive and defensive security the hands-on way. Guides, CTF writeups, interactive quizzes, a virtual hacker playground, and more. All free and hacker-friendly.
Structured progression from networking basics through offensive and defensive security, with 61 checkpoint quizzes along the way.
Phase 0: Lab Setup →Detailed guides on Nmap, Burp Suite, Metasploit, Hashcat, and 24 more tools. Not just flags — real methodology for real engagements.
Read guides →Quick-reference sheets you'll actually use during engagements. Copy-paste ready commands for every situation.
View sheets →Step-by-step walkthroughs of HackTheBox machines with interactive terminals. See real attacks in action.
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.
