Pery bootkit for Windows 8

Security researcher admitted that the virus has developed a new operating system, Windows 8, which is loaded at boot on older PCs.

Peter Klyayssner said his bootkit called Stoned Lite, can not circumvent the protective mechanisms of Windows 8 on the new devices. On his Twitter page, he wrote that bootkit will not load if your computer has UEFI, Unified Extensible Firmware Interface, is considered the replacement Bios ROM.Stoned Lite also can not avoid Secured Boot, which scans the boot device for invalid signatures before startup.

Previous bootkit, called Stoned, worked on all operating systems from Windows 2000 to Windows 7, and by the presence of the master boot record to boot before the start Windows. Stoned Lite can do the same on Windows Server 2008 and Windows 8, shared developer and researcher who lives in Vienna. Bootkit bypasses UAC and since it weighs only 14 KB, it can be loaded from USB or CD-ROM.

Klyayssner said he plans to tell more about the conference bootkit Malcon, which will be held this week in India.

The September statement of Microsoft that the company plans to use UEFI, raised the suspicion of the open source community, who claimed that this innovation will make it more difficult to use systems such as Linux and FreeBSD on the computers that have installed several systems. Microsoft has rejected such claims, but many critics – in disarray.

Whatever it was, the inability to penetrate the Stoned Lite UEFI and Secured Boot is proof that the system works as advertised and. At least for the moment it is.
