The design phase of an ELF virus may be considered an artistic endeavor, requiring creative thinking and clever constructs; many passionate coders will agree with this. Meanwhile, it is a great engineering challenge that exceeds the regular conventions of programming, requiring the developer to think outside conventional paradigms and to manipulate the code, data, and environment into behaving a certain way. At one point in time, I did a security assessment at a large antivirus (AV) company for one of their products. While talking with the developers of the AV software, I was amazed that next to none of them had any real idea of how to engineer a virus, let alone design any real heuristics for identifying them (other than signatures). The truth is that virus writing is difficult, and requires serious skill. There are a number of challenges that come into play when engineering them, and before we discuss the engineering components, let's look at what some...

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.
