As virtualization becomes more popular, so does the need to ensure that the platform is secure. Of course one of the biggest concerns is a compromise of the virtual host server. This can lead to hyper-jacking attacks when a hypervisor host is compromised. Hyper-jacking attacks attempt to take control of the hypervisor by the following methods:
• Injecting a rogue hypervisor beneath the original hypervisor
• Directly obtaining control of the original hypervisor
• Running a rogue hypervisor on top of an existing hypervisor
If multiple hosts were infected, this can lead to a guest-hopping attack in which a rogue server could bounce from virtual server host to virtual server host. It would be like chasing a ghost. A compromise of the hyper-visor host could allow a hacker to morph a virtual server running on the host into a compromised machine. Then the virtual server guest would change into a “Mr. Smith” agent, which could carry out a variety of attacks. . . .
