“Handbook for CTFers: Zero to One” was written by the Nu1L team, one of China’s top CTF teams. As for Jeopardy-style CTFs, the content in the first 10 chapters of this book not only covers traditional categories of tasks like WEB, PWN and Crypto, but also includes some of the latest hot topics and techniques, such as blockchain. Case studies are provided for all of these types.

Onsite Attack-Defend-style CTFs and penetration testing are introduced in Chapter 11 and Chapter 12.

In order to help readers gain the most from the book, we have developed the N1Book platform, which addresses practical questions for different task categories.

The book offers beginners a reliable, systematic tutorial on CTF competition. At the same time, it includes real case studies and a wealth of our competition experience, making it a valuable asset for experienced CTF players.
