Last week I wrote up a post regarding a new bootkit virus for Windows 8 that security researcher Peter Kleissner discovered. It was initially thought that this new bootkit virus was able to fool the new UEFI security feature that Microsoft has put in Windows 8, but it turned out that it doesn’t actually. However this bootkit has the ability to bypass the Windows UAC and gain administrator privileges and access to all user accounts.
Peter has now posted a video which demonstrates the bootkit called Stone Lite in action so you can see for yourselves just how simple it is. It’s only a mere 14kb file but it has the potential to pretty much unlock your whole computer.
As I mentioned in my previous post on this, Peter has already developed bootkits which have a similar effect for Windows 7, Windows Vista and XP. The code is also up and available on his site for anyone to have a look at. He’s also said that this exploit will only work on systems running legacy BIOS’s and doesn’t work on systems with the new UEFI technology.
Of course, Peter has informed Microsoft about this exploit several weeks ago and also passed on his recommendations to prevent it from being an issue in the final build of Windows 8.
