A Technique for Remote Detection of Certain Virtual Machine Monitors

In English The ability to detect a virtualized environment has both malicious and non-malicious uses. This paper reveals a new exploit and technique that can be used to remotely detect VMware Workstation, VMware Player and VirtualBox. The detection based on this technique can be done completely passively in that there is no need to have access to the remote machine and no network connections are initiated by the verifier. Using only information in the IP packet together with information sent in the user-agent string in an HTTP request, it is shown how to detect that the traffic originates from a guest in VMware Workstation, VMware Player or VirtualBox client. The limitation is that NAT has to be turned on and that the host and guest need to run different operating system families, e.g., Windows/Linux.
