### Preface
In the world of network security, CTF (Capture The Flag) is undoubtedly one of the most exciting fields. From cracking passwords to identifying vulnerabilities, from reverse engineering to network confrontation, CTF competitions provide a platform for countless young people who love technology to showcase their talents and challenge their limits. It is in this field filled with unknowns and possibilities that I found my passion and direction. As the fifth president of the Zhonganxin Network Security Association, I have the privilege of leading our team through many challenges, from initial ignorance to today’s expertise. We have experienced countless late nights of research and teamwork. This book was created with the hope of sharing my experiences and insights with others, allowing more people to appreciate the charm of network security. In China, I have felt the warmth of support from family, friends, teachers, and classmates. They have been an indispensable source of motivation on my journey towards my dreams. I am especially grateful to my family for their silent support while I focused on research; to my teachers, whose teachings gave me the courage to explore the world; to my classmates and teammates, who fought alongside me in various competitions and grew together; and to my fans who have always supported me. Your encouragement has helped me keep moving forward. This book is not just the result of individual efforts; it is also a product of collective wisdom. Behind every knowledge point and skill lies countless discussions and experiments, as well as the guidance and inspiration from many predecessors. As you open this book, I hope it becomes more than just a tool for improving your skills—it is also a gateway to a broader world of network security. I wish you find joy and achievements within it. Let us stand on the shoulders of giants and explore the infinite possibilities of network security! **Author: Pinocchio Also Wants to Be a Hacker**
