Virtual Machine Rebuilding

Virtual Machines are one of the most controversial protection methods used nowadays. I try to show how virtual machines are created by examining the full reversed source code of the VM used in the T2'06 challenge, worth $1'500. It explains how to code a VM and helps those who wanted to analyse such challenge by giving direct access to its source code and its structures. The RE-built source code of T2'06 is in appendix.

VX Reversing

Written by E. Abril

Side Story
Virtual Machine Rebuilding

For many years, Virus Writers and Reverse Code Engineers have independently studied common topics. As a consequence, these two subjects have grown up as, apparently, unrelated disciplines. NOT ANY LONGER. This is the first of a serie of issues dealing with one of the most interesting topics in Reverse Code Engineering (RCE): Virus Reversing. In each article, we will try to analyze a virus or technique of special relevance for the RCE community, a small "piece of art" created by some of the elite VXers, of course from a RCE's view point.
