Book Description:

Unlock 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.
