Computer mice can eavesdrop on private conversations, researchers discover

High-end computer mice can be used to eavesdrop on the voice conversations of nearby PC users, researchers from the University of California, Irvine, have shown in a new proof-of-concept demonstration.

Given the catchy name ‘Mic-E-Mouse’ (Microphone-Emulating Mouse), the ingenious technique outlined in Invisible Ears at Your Fingertips: Acoustic Eavesdropping via Mouse Sensors is based on the discovery that some optical mice pick up incredibly small sound vibrations reaching them through the desk surfaces on which they are being used.

These vibrations could then be captured by different types of software on PC, Mac or Linux computers, including non-privileged ‘user space’ programs such as web browsers or games engines or, failing that, privileged components at OS kernel level.
