Overview of this book

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.

ELF header

When opening an ELF file, you will see that it always begins with the ELF header. This header contains a structured series of bytes that provide essential information about the ELF file. The ELF header includes the following:

  • The file is an ELF file
  • The type of ELF
  • The offset to find another section header within the file

The ELF header in ELF files serves as the initial segment, containing crucial details about the file’s organization and layout.

The ELF header is represented as a C struct called Elf64_Ehdr for 64-bit ELF files. The format and contents of this header can be found in the elf.h file located in /usr/include/ or in the ELF specification. You can find this header in the Debian system.

How to identify an ELF header

Let’s look at Figure 2.2, which shows the layout of an ELF file.

Figure 2.2: Location of the ELF header

As seen in Figure 2.2, you can see the position of the ELF header and the...
