Thwarting VM Detection by Tom Liston and Ed Skudis
I believe most of you have at least heard of VMware, Microsoft Virtual PC, or the recent VirtualBox (http://www.virtualbox.org/) These are virtualization software. They create virtual machine environment (called guest) that runs on your local computer (called host). These software are pretty useful especially when it comes to analyzing malwares or other uses. *ahem* 😉
This is a neat paper about how to detect a VME, and about how to prevent it against detection. Recommended read.
