Sensors can tap into mobile vibrations to eavesdrop remotely, researchers find
Oct 2022, phys.org
They could detect the vibrations of a cell phone's earpiece and decipher what the person on the other side of the call was saying with up to 83% accuracy using an off-the-shelf automotive radar sensor and a novel processing approach (called an "eavesdropping attack").

AI-driven 'thermal attack' system reveals computer and smartphone passwords in seconds

After users type their passcode, a thermal camera can take a picture that reveals the heat signature of where their fingers have touched the device; the brighter an area appears in the thermal image, the more recently it was touched.
