This Technique Works By Forming A Sonar System By Using Sound Waves To Track The Position Of Your Fingers On Your Phones Screen. 

This Technique Has Been Dubbed As SonarSnoop.


To Use This Hack, A Malicious App Needs To Be Running On The Phone For Emitting Sound Waves From The Speaker, And The Bounced Off Waves From The Users Fingers Are Captured By The Microphone To Identify The Pattern.
