Author Comments:

The purpose of this course is to provide a hands on introduction to Intel hardware support for virtualization. The first part will motivate the challenges of virtualization in the absence of dedicated hardware. This is followed by a deep dive on the Intel virtualization “API” and labs to begin implementing a blue pill / hyperjacking attack made famous by researchers like Joanna Rutkowska and Dino Dai Zovi et al. Finally a discussion of virtualization detection techniques.

Hopefully after this course the student will be able to identify, understand, and implement various hypervisor concepts. As virtualization is a powerful tool, it is very important to understand its strengths and weaknesses. The author believes that hands-on experience with virtualization is practical and accessible, particularly when presented alongside other Open Security Training materials.
