Reverse Engineering Armv8-A Systems: A practical guide to kernel, firmware, and TrustZone analysis

Explore reverse engineering in Armv8-A-based Arm devices, develop the skills to analyze binaries, and leverage cutting-edge security hardening features through hands-on techniques and expert insightsKey FeaturesMaster key aspects of Armv8-A, including register, exception handling, and TrustZoneBuild new reversing skills for kernel binaries, such as *.ko and vmlinux, for firmware analysisUnderstand Armv8-A's latest security featuresPurchase of the print or Kindle book includes a free PDF eBookBook DescriptionUnlock the secrets hidden in binary code without needing the source! Written by a Linux kernel engineer and author with over 14 years of industry experience, this book lays a solid foundation in reverse engineering and takes you from curious analyst to expert. You’ll master advanced techniques to dissect kernel binaries, including kernel module files, vmlinux, and vmcore, giving you the power to analyze systems at their core.This practical, three-part journey starts with the essentials of reverse engineering, introducing the key features of Armv8-A processors and the ELF file format. The second part walks you through the reverse-engineering process, from Arm environment setup to using static and dynamic analysis tools, including innovative methods for analyzing kernel binaries and the powerful debugging tool uftrace. The final part covers security, exploring TrustZone and the latest security techniques to safeguard Arm devices at the hardware level.By the end of this reverse engineering book, you'll have comprehensive Armv8-A expertise and the practical skills to analyze any binary with confidence while leveraging advanced security features to harden your systems.What you will learnUnderstand the organization of Arm assembly instructionsDisassemble assembly code without using C codeWork with reverse engineering tools, such as GDB and binary utilityApply reversing techniques for both user space and kernel binariesGet to grips with static and dynamic binary analysis processesGet a solid understanding of the powerful debugging tool, uftraceAnalyze TrustZone and the advanced security features provided by Armv8-AWho this book is forThis book is for professionals and enthusiasts interested in reverse engineering and debugging on Armv8-A-based devices.
