Security researchers demonstrated how to take control of a computer running Microsoft’s upcoming Windows 7 operating system at the HITB in Dubai — “called VBootkit 2.0 to take control of a Windows 7 virtual machine while it was booting up. They demonstrated how the software works at the conference. “There’s no fix for this. It cannot be fixed. It’s a design problem.” VBootkit clocks in at 3KB in size, allows an attacker to take control of the computer by making changes to Windows 7 files that are loaded into the system memory during the boot process. Since no files are changed on the hard disk, VBootkit 2.0 is very difficult to detect,” said researchers.
