Laiho himself notes that he used it as long ago as NT when he pressed SHIFT+F10 so that he could play solitaire while doing a new NT install. While the SHIFT+F10 feature has existed with earlier versions of Windows, and could also be used to bypass BitLocker on Windows 7 & 8, it is only with the advent of Windows 10's inplace upgrades that it has become a real vulnerability. He also advises that companies should not allow unattended updates, and should "Keep very tight watch on the Insiders."

Laiho adds that there is also the risk of an external threat with access to a computer that just "waits for it to start an upgrade to get into the system." He is sufficiently concerned to have advised his customers to use Microsoft's Long Time Servicing Branch (LTSB) for the time being. "The risk exists," he said, "albeit a difficult one to exploit." Nevertheless, Patel told SecurityWeek, "Microsoft does tend to telegraph the timing of its feature updates." This would give a disgruntled but tech-savvy employee a window in which to obtain elevated access to the system, and do whatever he wishes. While technically possible, if the attacker has ownership of the laptop, he would probably have easier methods of defeating BitLocker. He considered whether a laptop could be stolen, and the system 'tricked' into assuming a feature update. "And of course that this doesn't require any external hardware or additional software."Īndy Patel, a security expert with F-Secure, has been considering how this could be used in a live attack. Nevertheless, "The real issue here is the Elevation of Privilege that takes a non-admin to SYSTEM (the root of Windows) even on a BitLocker (Microsoft's hard disk encryption) protected machine," adds Laiho.

The attacker almost certainly needs physical access to the target machine during a relatively short time frame. It is the ability to bypass BitLocker that makes this a serious if not a major issue. "This sadly," he says, "allows for access to the hard disk as during the upgrade Microsoft disables BitLocker." This includes the troubleshooting feature that allows you to press SHIFT+F10 to get a Command Prompt. "There is a small but CRAZY bug in the way the 'Feature Update' (previously known as "Upgrade") is installed," he wrote. Windows expert Sami Laiho blogged about the issue yesterday.

For example, during the more frequent feature updates in Windows 10 (as opposed to the old practice of providing a distinct new OS version), pressing SHIFT+F10 gives the user admin privileges while BitLocker is disabled.
