Security researchers from the University of Michigan and Zhejiang University in China have published a paper on an acoustic attack vector that could crash a mechanical hard drive, leading to damage for both the hardware and software. The attack does not require fancy equipment, either—an attacker could use regular, built-in speakers or nearby emitters to cause persistent errors on the target system. "Our experiments show that audible sound causes the head stack assembly to vibrate outside of operational bounds; ultrasonic sound causes false positives in the shock sensor, which is designed to prevent a head crash. The problem poses a challenge for legacy magnetic disks that remain stubbornly...
