Hackers Could Crash Your Mechanical Hard Disks Using Just Sound Waves

After protecting your computer confronting hacking attempts over a network, or via a plug-in USB drive, y'all may soon need an acoustically sealed room to proceed your data safety from hackers.

According to a report by Princeton and Purdue Academy researchers, disrupting a hard disk's normal operation is a relatively easy task using sound waves. Their study was motivated by the fact that due to their vital office in diverse systems, hard disks are an "an interesting target for a plethora of attackers."

Using a speaker emitting audio waves at detail resonant frequencies, the researchers were successfully able to perform a Denial of Service (DoS) attack on a hard disk drive connected to a DVR, and some other connected to a Desktop PC.

The DVR stopped recording in one case the assault was performed, and the Desktop PC essentially went into a BSOD state — the infamous Blue Screen of Death – in Windows.

The reason this works is because of the primal way in which hard disks utilize mechanical parts, i.eastward the head and spinning disks. To preclude the head from scratching the information platters, hard disks cease operations if there's a lot of vibration — a safe 'fail-safety' of sorts that has now been exploited as an attack vector. The sound waves, when targeted at the hard disk at a particular frequency, basically start resonating inside the hard disk drive, causing vibrations to increase steadily and finally forcing the hard disk to stop working.

Every hard disk drive has a particular resonant frequency, only according to the researchers, they didn't encounter whatever difficulties figuring out the advisable frequencies for a number of different hard-disks. They claimed that hackers wouldn't have any difficulties doing the same, either.

Since the attack performed during the study required the speaker exist prepare at a very detail angle, information technology's not yet something that will be used to exploit hard-drives on a mass scale. Simply this proof-of-concept shows hackers could figure out a clever way to actually use this attack vector in real life.
