Samsung: the fingerprint reader of the Galaxy S10 already trapped

A user has unlocked a Galaxy S10 using a 3D printed fingerprint. It took him about 15 minutes.

If the Galaxy S10 is not the first smartphone to have a fingerprint reader under the screen, Samsung differs from the competition by a hypersonic device and not optical. A system, according to the manufacturer, safer and secure, and yet a user took it in default.

How? By using a fingerprint printed in 3D! To achieve this, it takes about fifteen minutes according to him, and he details his method. First, like a scientific police engineer, he took a picture of an imprint left on a glass. Then with a photo editing software, he improved the image so that the footprint is better. It only took him three minutes.

Then there is the phase of 3D printing. He needed a few tries, and finally, he managed to get a 3D image. Using a glove, he places it on the screen, presses, and unlocks the device.

The author of this “hacking” explains in his video that on a stolen phone, there is a multitude of prints of its owner and that he could repeat the operation. He also recalls that it is all the more dangerous because a large number of applications are unlocked thanks to the fingerprint reader.

Whether it’s installing a paid application, accessing email or checking bank accounts, the fingerprint is most often used to confirm the identity and avoid entering a password or password. a code.

This flaw in the Samsung system is reminiscent of the face ID of the iPhone X, hacked from its launch with a  simple mask, but also that of the same Galaxy S10, lured by a  simple photo of the owner.

I attempted to fool the new Samsung Galaxy S10’s ultrasonic fingerprint scanner by using 3d printing. I succeeded.
