A team of researchers has developed an eavesdropping attack for Android devices that can, to various degrees, recognize the caller's gender and identity, and even discern private speech.
Named EarSpy, the side-channel attack aims at exploring new possibilities of eavesdropping through capturing motion sensor data readings caused by reverberations from ear speakers in mobile devices.
EarSpy is an academic effort of researchers from five American universities (Texas A&M University, New Jersey Institute of Technology, Temple University, University of Dayton, and Rutgers University).
