<p><b>Provides readers with a solid foundation in Arm assembly internals and reverse-engineering fundamentals as the basis for analyzing and securing billions of Arm devices</b> <p>Finding and mitigating security vulnerabilities in Arm devices is the next critical internet security frontier—Arm processors are already in use by more than 90% of all mobile devices, billions of Internet of Things (IoT) devices, and a growing number of current laptops from companies including Microsoft, Lenovo, and Apple. Written by a leading expert on Arm security, <i>Blue Fox: Arm Assembly Internals and Reverse Engineering</i> introduces readers to modern Armv8-A instruction sets and the process of reverse-engineering Arm binaries for security research and defensive purposes. <p>Divided into two sections, the book first provides an overview of the ELF file format and OS internals, followed by Arm architecture fundamentals, and a deep-dive into the A32 and A64 instruction sets. Section Two delves into the process of reverse-engineering itself: setting up an Arm environment, an introduction to static and dynamic analysis tools, and the process of extracting and emulating firmware for analysis. The last chapter provides the reader a glimpse into macOS malware analysis of binaries compiled for the Arm-based M1 SoC. Throughout the book, the reader is given an extensive understanding of Arm instructions and control-flow patterns essential for reverse engineering software compiled for the Arm architecture. Providing an in-depth introduction into reverse-engineering for engineers and security researchers alike, this book: <ul> <li>Offers an introduction to the Arm architecture, covering both AArch32 and AArch64 instruction set states, as well as ELF file format internals</li> <li>Presents in-depth information on Arm assembly internals for reverse engineers analyzing malware and auditing software for security vulnerabilities, as well as for developers seeking detailed knowledge of the Arm assembly language</li> <li>Covers the A32/T32 and A64 instruction sets supported by the Armv8-A architecture with a detailed overview of the most common instructions and control flow patterns</li> <li>Introduces known reverse engineering tools used for static and dynamic binary analysis </li> <li>Describes the process of disassembling and debugging Arm binaries on Linux, and using common disassembly and debugging tools </li></ul> <p><i>Blue Fox: Arm Assembly Internals and Reverse Engineering</i> is a vital resource for security researchers and reverse engineers who analyze software applications for Arm-based devices at the assembly level.
