Hackers can steal mobile data through fingerprints

On August 6, American researchers showed the public a new way to steal Android user data, including the use of fingerprint sensors. Currently, Samsung, HTC, and Huawei's mobile phone makers using Android have taken measures to address issues pointed out by researchers.

At the Black Hat conference, Yu Long Zhang and Tao Wei, researchers of security vendor FireEye, introduced a "fingerprint sensor surveillance attack" method. At the meeting, two researchers from the US Fire Eye Company demonstrated 4 This method of attacking user networks warned that users of Android phones such as Samsung, HTC, and Huawei may be attacked by hackers by using their fingerprints. This threat comes mainly from Android devices with fingerprint sensors, so mobile phone users such as Samsung, HTC and Huawei will face the risk of being hacked. At present, these companies have already fixed bugs pointed out by researchers. Since many Android phones do not completely lock the fingerprint sensor, the remote control allows hackers to steal the fingerprint image stored by the user in the affected mobile phone. And if you root your Android phone, the risk of your fingerprint being stolen will be even greater.

After fingerprint information is stolen, hackers can use this information to unlock your mobile phone and even complete mobile payment authentication. Although this type of equipment sales is lower than the iPhone. However, it is expected that at least half of smartphones will be equipped with fingerprint sensors by 2019, and the threat will increase. Fingerprints and passwords, after all, are not the same, and are a method of verification that accompanies the user for life. Once leaked, it will cause irreparable damage. However, although hackers can directly read the fingerprint sensor, they do not have an encryption key and they cannot obtain accurate fingerprint images.
