Windows Hello: Several posts mention that the authentication feature of Windows 10 are among the most secure out there.

But it turns out that Windows Hello can be misled with a simple photo just like Apple's Face ID.Windows Hello

The vulnerability was announced by Germaniki Security Syss at Full Disclosure.

According to the researchers, even if you have installed all the latest updates for builds 1703 or 1709, face recognition should be set from the start to be resistant to the attack.

The “simple attacks ” described in the researchers’ announcement are all variations using a “modified photo of an authorized user.” So with a simple photo an attacker can get into a locked Windows 10 system.

The default configuration of Windows Hello has "enhanced anti-spoofing" enabled, says Syss.

If enhanced anti-spoofing is enabled, depending on the version of Windows 10, a slightly different modified photo should be used, but for an attacker the effort is negligible.

The researchers tested the attack on a Dell Latitude running (build 1703), αλλά και σε ένα Surface Pro 4 running Windows build 1607.

Researchers have tried to change the Surface Pro setting to "enhanced anti-spoofing", but claim that the "LilBit USB IR camera only supports the default setting and can not be used with more secure face recognition settings".

The researchers released the following three videos as PoC:
