Security researchers have cracked Apple’s FaceID biometric system yet again.

But there’s an unusual caveat to this trick: to successfully unlock an iPhone, the attackers first need to make sure the victim is out cold.

The attack involves putting a pair of modified glasses on the victim’s face.

That, coupled with carefully placing a piece of tape over the glasses’ lenses, makes it possible to circumvent FaceID and log into a victim’s iPhone.

Of course, the exploit is fairly difficult to pull off considering the attackers would need to figure out how to put the glasses on a victim without waking them up.

The attack leverages a biometrics function called “liveness” detection, designed to tell apart “fake” versus “real” features on people.
