Index

Chapter 5. Linux Binary Protection

In this chapter, we are going to explore the basic techniques and motivations for obfuscation of Linux programs. Techniques that obfuscate or encrypt binaries or make them difficult to tamper with are called software protection schemes. By "software protection," we mean binary protection or binary hardening techniques. Binary hardening is not exclusive to Linux; in fact, there are many more products for the Windows OS in this technology genre, and there are definitely more examples to choose from for discussion.

What many people fail to realize is that Linux has a market for this too, although it largely exists for anti-tamper products used by the government. There are also a number of ELF binary protectors that were released over the last decade in the hacker community, several of which paved the way for many of the technologies used today.

An entire book could be dedicated to the art of software protection, and as the author of some...

"elfmaster" O'Neill

Ryan "elfmaster" O'Neill is a computer security researcher and software engineer with a background in reverse engineering, software exploitation, security defense, and forensics technologies. He grew up in the computer hacker subculture, the world of EFnet, BBS systems, and remote buffer overflows on systems with an executable stack. He was introduced to system security, exploitation, and virus writing at a young age. His great passion for computer hacking has evolved into a love for software development and professional security research. Ryan has spoken at various computer security conferences, including DEFCON and RuxCon, and also conducts a 2-day ELF binary hacking workshop. He has an extremely fulfilling career and has worked at great companies such as Pikewerks, Leviathan Security Group, and more recently Backtrace as a software engineer. Ryan has not published any other books, but he is well known for some of his papers published in online journals such as Phrack and VXHeaven. Many of his other publications can be found on his website at http://www.bitlackeys.org.
