"The book takes you from the beginning of your Ghidra journey to the end. From an introduction to disassembly and working with the basics of Ghidra to scripting in Ghidra to extend its capabilities, this book covers it all. . . . a perfect 5/5 for me."
—Tyler Reguly, Tripwire Book Club
"I would highly recommend this book. Rather than simply being a Ghidra user guide, the authors did an exceptional job of laying out many of the fundamental concepts involved in software reverse engineering."
—Craig Young, Principal Security Researcher, Tripwire
"I enjoyed The Ghidra Book, and it was a good starting point for me in entering the world of reverse engineering and the many different tools that are accessible due to being open-sourced. I encourage anyone that has an interest in reverse engineering or who just wants to investigate cool open-sourced tools to give The Ghidra Book a read."

抜粋
INTRODUCTION
Our goal in writing this book is to provide a resource that introduces Ghidra to both current and future reverse engineers. In the hands of a skilled reverse engineer, Ghidra streamlines the analysis process and allows users to customize and extend its capabilities to suit their individual needs and improve their workflows. Ghidra is also very accessible to new reverse engineers, particularly with its included decompiler that can help them more clearly understand the relationships between high-level language and disassembly listings as they begin exploring the world of binary analysis.
Writing a book about Ghidra is a challenging undertaking. Ghidra is a complex open source reverse engineering tool suite that is continually evolving. Our words describe a moving target, as the Ghidra community continues to improve and extend its capabilities. As with many new open source projects, Ghidra has begun its public life with a rapid string of evolutionary releases. A primary goal while writing this book has been to ensure that as Ghidra evolves, the book’s content continues to provide readers with a wide and deep foundation of knowledge to understand and effectively utilize current and future Ghidra versions to address their reverse engineering challenges. As much as possible, we have tried to keep the book version-agnostic. Fortunately, new releases of Ghidra are well-documented, with detailed listings of changes that provide version-specific guidance should you encounter any differences between the book and your version of Ghidra.
About This Book
This book is the first comprehensive book about Ghidra. It is intended to be an all-encompassing resource for reverse engineering with Ghidra. It provides introductory content to bring new explorers to the reverse engineering world, advanced content to extend the worldview of experienced reverse engineers, and examples for rookie and veteran Ghidra developers alike to continue to extend Ghidra’s extensive capabilities and become contributors to the Ghidra community.
Who Should Read This Book?
This book is intended for aspiring and experienced software reverse engineers. If you don’t already have reverse engineering experience, that’s okay, as the early chapters provide the background material necessary to introduce you to reverse engineering and enable you to explore and analyze binaries with Ghidra. Experienced reverse engineers who want to add Ghidra to their toolkits might choose to move quickly through the first two parts to gain a basic understanding of Ghidra and then jump to specific chapters of interest. Experienced Ghidra users and developers may choose to focus on the later chapters so that they can create new Ghidra extensions and can apply their experience and knowledge to contribute new content to the Ghidra project.
What’s in This Book?
The book is divided into five parts. Part I introduces disassembly, reverse engineering, and the Ghidra project. Part II covers basic Ghidra usage. Part III demonstrates ways you can customize and automate Ghidra to make it work for you. Part IV takes a deeper dive into explaining specific types of Ghidra modules and supporting concepts. Part V demonstrates how Ghidra can be applied to some real-world situations a reverse engineer is likely to encounter.
Part I: Introduction
Chapter 1: Introduction to Disassembly
This introductory chapter walks you through the theory and practice of disassembly and discusses some of the pros and cons associated with the two common disassembly algorithms.
Chapter 2: Reversing and Disassembly Tools
This chapter discusses the major categories of tools available for reverse engineering and disassembly.
Chapter 3: Meet Ghidra
Here you get to meet Ghidra and learn a little bit about its origin and how you can obtain and start using this free open source tool suite.
Part II: Basic Ghidra Usage
Chapter 4: Getting Started with Ghidra
Your journey with Ghidra begins in this chapter. You’ll get your first glimpse of Ghidra in action as you create a project, analyze a file, and begin to understand the Ghidra graphical user interface (GUI).
Chapter 5: Ghidra Data Displays
Here you’ll be introduced to the CodeBrowser, Ghidra’s main tool for file analysis. You’ll also explore the primary CodeBrowser display windows.
Chapter 6: Making Sense of a Ghidra Disassembly
This chapter explores the concepts that are fundamental to understanding and navigating Ghidra disassemblies.
Chapter 7: Disassembly Manipulation
In this chapter, you’ll learn to supplement Ghidra’s analysis and manipulate a Ghidra disassembly as part of your own analysis process.
Chapter 8: Data Types and Data Structures
In this chapter, you will learn how to manipulate and define simple and complex data structures found within compiled programs.
Chapter 9: Cross-References
This chapter provides a detailed look at cross-references, how they support graphing, and the critical role they play in understanding a program’s behavior.
Chapter 10: Graphs
