The guys from the X-Lab team at Tencent Security got to the ultrasound fingerprint sensor. At one of the hacking events in Shanghai, they clearly demonstrated how to trick a scanner. It took 20 minutes and no laborious manipulations had to be done.

The method is based on the principle of creating a copy of a papillary pattern. To begin with, volunteers were asked to touch a regular glass. Then the fingerprint was photographed, the photo was digitized through a special application.

A few minutes later, a “fingerprint” of a fingerprint was created, with the help of which it was possible to unlock three smartphones and two more devices that use a fingerprint sensor to identify the user.

One of the X-Lab employees said that they used equipment that cost only $ 140 to create a “clone” of the fingerprint. And you also need a smartphone and a special application.

The proposed method allows you to crack not only ultrasound scanners, but also capacitive and optical sensors. As a preventative measure against this hack, the guys from Tencent Security suggested users to avoid leaving their fingerprints on surfaces.
