our version of VirtualBox does not use/support hardware-accelerated graphics. We needed a GPU driver first. Thanks for the link. It is important to keep such attack vectors in mind. It also bears the question: Does your BIOS clear all physical memory at boot time? If not, couldn't an attacker with physical access to a machine (i.e., a stolen laptop that may still be locked with a screensaver) reset the machine, boot a custom OS from a USB stick, and scan the memory for credentials? What would be a viable defense against such a scenario? Cheers Norman -- Dr.-Ing.
