Optical Mice Can Be Used to Eavesdrop on Conversations

🖱️ Researchers at the University of California, Irvine demonstrated a proof-of-concept called Mic-E-Mouse, showing that high-end optical mice can pick up desk-transmitted voice vibrations and be used to reconstruct nearby conversations. The attack can be executed on PC, Mac and Linux by non-privileged user-space programs, and Wiener and neural-network filtering was used to enhance muffled signals into intelligible speech. Practical limits include a quiet environment, thin desks (≈3 cm or less), mostly stationary mice and very high-DPI hardware; placing a rubber pad or mouse mat under the mouse prevents the leakage.
