This book is your step-by-step guide to designing and exploiting custom Capture the Flag (CTF) environments. From Windows and Linux labs to mobile, wireless, and crypto challenges, you'll craft realistic targets, weaponize vulnerabilities, and chain exploits like a pro. Using Kali Linux, Metasploit, Nmap, and custom scripts, you'll master both the art of CTF design and the tactics of advanced offensive security. Perfect for red teamers, penetration testers, and cyber range builders.More than just a hacking manual, this is a blueprint for creating scalable, reusable CTF ranges that sharpen technical skills, test real-world attack paths, and deliver high-impact training experiences. Whether you're hosting a DEFCON-style competition, building an internal red team lab, or levelling up your own skills, this book will arm you with the knowledge to engineer, deploy, and dominate your own cyber battlegrounds.
