Attackers Can Use Sonic and Ultrasonic Signals to Crash Hard Drives

By [email protected] (Swati Khandelwal) 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
