Microsoft has released updates earlier this month to patch a vulnerability in the Windows 10 Hello facial recognition system that allows an attacker to bypass the facial scan with a printed photo. The feature uses near infrared (IR) imaging to authenticate and unlock Windows devices. Researchers say that by using a laser color printout of a low-resolution (340x340 pixels) photo of the device owner's face, modified to the near IR spectrum, they were able to unlock several Windows devices where Windows Hello had been previously activated. The attack worked even if the "enhanced anti-spoofing" feature had been enabled in the Windows Hello settings panel.
