Learning Linux Binary Analysis

4.8 (10)
By: "elfmaster" O'Neill

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.

Chapter 4. ELF Virus Technology – Linux/Unix Viruses

The art of virus writing has been around for several decades now. In fact, it goes all the way back to the Elk Cloner Apple virus that was successfully launched in the wild in 1981 through a floppy disk video game. Since the mid '80s and through the '90s, there have been various secret groups and hackers who have used their arcane knowledge to design, release, and publish viruses in virus and hacker e-zines (see http://vxheaven.org/lib/static/vdat/ezines1.htm).

The art of virus writing is usually of great inspiration to hackers and underground technical enthusiasts, not because of the destruction that they are capable of, but rather the challenge in designing them and the unconventional coding techniques that are required to succeed in programming a parasite that keeps its residency by hiding in other executables and processes. Also, the techniques and solutions that come with keeping a parasite stealthy, such...
