Researchers have now unveiled a new vulnerability with Android fingerprint sensors that could potentially lead to a big security threat. Two researchers Tao Wei and Yulong Zhan outlined many threats to Android devices with fingerprint sensors, while claiming that the iPhone’s fingerprint sensor was ‘quite secure’.
ZDNet reports that the researchers found the fingerprint sensors on Huawei, Samsung and HTC devices more under threat. The duo stressed that a particular attack that they called the ‘fingerprint sensor spying attack’ harvested fingerprints in large scale. Vulnerabilities were especially found on HTC One Max and Samsung Galaxy Note 5, where the researchers found that a hacker could easily get a fingerprint image as the makers haven’t fully secured their sensors.
“In this attack, victims’ fingerprint data directly fall into attacker’s hand. For the rest of the victim’s life, the attacker can keep using the fingerprint data to do other malicious things,” Zhang said.
In comparison, the duo lauded the TouchID scanner on the iPhone and said that it was ‘quite secure’. “Even if the attacker can directly read the sensor, without obtaining the crypto key, [the attacker] still cannot get the fingerprint image,” he said.
