Creating Code Obfuscation Virtual Machines presented at REcon 2008

by Craig Smith,


Summary : This is the VM Creation 101 talk. The talk details what a virtual machine is and how they are used. It focuses on embedded virtual machines used for code obfuscation. Specific coding examples are provided on how to write your own opcode interpreter. Code samples on how to embed your newly created VM into a C application is also provided. Additional obfuscation techniques for the VM are discussed and even though this is a 101 course a solid understanding of x86 assembler is required.
