Process-level virtualization is increasingly being used to enhance the security of software applications from reverse engineering and unauthorized modification (called software protection). Process-level Virtual Machines (PVMs) can safeguard the application code at run time and hamper the adversary's ability to launch dynamic attacks on the application. This dynamic protection, combined with its flexibility, ease in handling legacy systems and low performance overhead, has made process-level virtualization a popular approach for providing software protection. While there has been much research on using process-level virtualization to provide such protection, there has been less research on attacks against PVM-protected software.
