Carving ELF Files

The blog by Joren Vrancken discusses the process of carving ELF files, which is a common task in digital forensics and reverse engineering, especially when analyzing malware samples. The blog explains how to determine the beginning and end of an ELF executable by examining its headers. ELF files consist of an ELF file header, program headers table, section headers table, and data sections. The blog details the structure of these headers and tables, such as the ELF file header containing general information about the executable. It also explains the significance of the program headers table in loading the executable into memory and the section headers table in describing the data stored in the file. The blog provides insights into computing the size of an ELF file by identifying the end of each part within the file. Additionally, it includes an example computation using the '/bin/ls' executable to demonstrate the methodology of determining the size of an ELF file by analyzing its headers and sections.
