In a new and concerning development, researchers from China and the United States have revealed a unique method of biometric hacking that could potentially compromise the security of our smartphones. As smartphones have become an integral part of our lives, containing a wealth of private information, manufacturers have been constantly striving to improve security measures.
One popular method of protection employed in modern smartphones is fingerprint scanning. By simply placing their finger on the reader, users can conveniently and securely unlock their devices or access other services. The uniqueness of fingerprints made this method seem foolproof. However, researchers have now discovered a new and alarming vulnerability.
This new attack, known as PrintListener, allows hackers to determine a person’s fingerprint by analyzing the sound of their finger moving across the touch screen. As a result, this method can bypass the Automatic Fingerprint Identification System (AFIS) and gain access to the device, private data, and even payment systems.
PrintListener takes advantage of the acoustic characteristics produced by a user’s finger as it moves across the touchscreen, extracting the unique fingerprint pattern. Special algorithms are required to convert the audio signal into a fingerprint. Astonishingly, researchers claim they can successfully identify partial fingerprints in approximately 1 out of 4 attempts, and complete fingerprints in approximately 1 out of 10 attempts.
Cybercriminals could potentially intercept the sounds of finger movements through popular messaging applications, such as Discord, Skype, WeChat, and FaceTime, which often have microphones enabled during chat sessions. This amplifies the risk and potential impact of this biometric attack.
Manufacturers will need to address this vulnerability to ensure the ongoing security of our smartphones. In the meantime, users should be cautious when using fingerprint scanning as their primary method of authentication, and consider employing additional security measures to protect their sensitive data.
