Overview of this book

Learning Linux Binary Analysis is packed with knowledge and code that will teach you the inner workings of the ELF format, and the methods used by hackers and security analysts for virus analysis, binary patching, software protection and more. This book will start by taking you through UNIX/Linux object utilities, and will move on to teaching you all about the ELF specimen. You will learn about process tracing, and will explore the different types of Linux and UNIX viruses, and how you can make use of ELF Virus Technology to deal with them. The latter half of the book discusses the usage of Kprobe instrumentation for kernel hacking, code patching, and debugging. You will discover how to detect and disinfect kernel-mode rootkits, and move on to analyze static code. Finally, you will be walked through complex userspace memory infection analysis. This book will lead you into territory that is uncharted even by some experts; right into the world of the computer hacker.

libecfs – a library for parsing ECFS files


The ECFS file format is very easy to parse with traditional ELF utilities, such as readelf, but to build parsing tools that are custom, I highly recommend that you use the libecfs library. This library is specifically designed for easy parsing of ECFS core files. It will be demonstrated with slightly more details later in this chapter when we look at designing advanced malware analysis tools to detect infected processes.

libecfs is also used in the ongoing development of the readecfs utility, which is a tool for parsing ECFS files, and is very similar to the commonly known readelf utility. Note that libecfs is included with the ECFS package on the GitHub repository.
