Security researchers demonstrated how to bypass the Windows Hello facial recognition that is used in Windows 10 as a login mechanism. Windows Hello is a Windows 10 security feature that allows users to unlock the device with a users fingerprint, iris scan, or face. An attacker could exploit the vulnerability to login systems running the Windows 10 OS. Microsoft already fixed the vulnerability with the release of July Patch Tuesday security updates. The flaw is very difficult to exploit, an attacker with physical access to the computer needs a good infra-red image of the user.”]
