A team of researchers from Tencent Security X-Lab demonstrated at the GeekPwn 2019 event in Shanghai how a smartphone can be hacked using fingerprints left on a glass. Researcher Chen Yu scanned the glass's fingerprints using an app on his phone, and then, in 20 minutes, created a physical copy of the fingerprints that could trick the scanners of smartphones or cars.

"The hardware required for this attack was worth over 1,000 yuan (roughly $ 140) in total, and the hardware was just one phone and an application," the researcher told The Paper.

According to the researchers, they were the first to hack the ultrasonic fingerprint sensor - one of the most common types used in smartphones, along with capacitive and optical sensors.

However, we will remind, earlier this month, the British showed how you can trick the ultrasonic fingerprint sensor in the Samsung Galaxy S10. The woman purchased a $ 3 protective gel film and found that she could unlock the device with an unregistered finger. As it soon turned out, her family can also unlock the phone. Samsung has already released an update to address this issue. Also in April of this year, a user of the Reddit forum under the pseudonym Darkshark managed to bypass the smartphone's security system using a three-dimensional fingerprint model.
