Attackers Can Use Sonic and Ultrasonic Signals to Crash Hard Drives

Researchers have demonstrated how sonic and ultrasonic signals (inaudible to human) can be used to cause physical damage to hard drives just by playing ultrasonic sounds through a target computer's own built-in speaker or by exploiting a speaker near the targeted device.

Similar research was conducted last year by a group of researchers from Princeton and Purdue University, who demonstrated a
