Offensive Security, Explained Properly

Hands-on walkthroughs of the techniques real attackers use — Active Directory attacks, privilege escalation, web exploitation — with the actual tool syntax, and the detection and defensive controls that stop each one. Written by practitioners, for practitioners.

⚠ For authorised testing and education only. Every technique below is demonstrated against controlled lab environments. Using these techniques against systems you do not own or have explicit written permission to test is illegal. Each walkthrough includes a Detection & Defense section — because understanding the attack is how you stop it.
