Your computer's hard drive may be listening to you - and recording everything

The computers' hard drive can be used as a microphone, allowing intruders to listen to the conversations between people around the device.

To demonstrate how to turn a computer hard drive into a microphone, Connor Bolton and his colleagues at the University of Michigan, USA, used the feedback system that helps position the read head above the magnetic disk.

When the read head is struck by sound waves, the mechanical vibrations interfere with the voltage signal produced by the drive position sensors.

By monitoring this signal, Bolton was able to make high quality recordings of people talking near the computer.

According to the team, malicious software can use this technique to record audio and then secretly send it to a remote site, invading a home or office without having to go in there to plant a microphone spy.

I could not find any proof of these claims in the publication. You have made all this up.

Stupid shits like you is why we ended up in a full surveillance dystopia.

Don't break the law and there is nothing to fear, because by following it, you are free from it. Pretty simple.

SSD?

...along with stupid shits like this, why we are already under 24/7 surveillance, only to get worse in the future when nano sensors powered by infrared rectennas will enter your colons to make sure Big Brother really knows everything about you.

It's ok OP, bunch of dipshit dumbasses in this thread can't even comprehend the implications of this kind of security research.

I didn't either see anything about conversations not to say it's impossible,

Dumbasses,

Researchers already showed data transfer between two computers with temperature fluctuations alone.

While this maybe true. It has nothing to do with this Journal Publication. You are the stupid blind bullshit here my man.

An international team of researchers from the University of Michigan and Zhejiang described a new method of acoustic attack through third-party channels, which makes it possible to turn a hard disk drive (HDD) into a listening device.

Any vibration can alter the position of a hard driveSEEAMAZON_ET_135 See Amazon ET commerce, so a modern hard drive is sensitive enough to pick up even minute disturbances in the platter. Yes, even human speech shows up in the PES data. Of course, hard drives don’t broadcast PES readings for everyone to analyze.

In a proof of concept experiment, the team installed modified firmware on the drives that could record the PES measurements. Using that data, the researchers created high-quality recordings of human voices. In another test, the PES data was sufficient to reconstruct music playing near the hard drive. It was so accurate that the music ID app Shazam was able to identify the song.

Either you are an idiot or you did not read the link I posted.
I have another article on the subject

(Portuguese, if you do not understand this language use a translator)

The Portuguese article is real, but it is wrong, and not based on the the english pdf. The english paper is mostly about errors that an attacker could cause in a computer system that have direct physical access to. However, it is a stupid situation because such an attacker can just put a hammer to the hard drive to cause errors as well.

Fuck you this has nothing to do with what the OP posted. The article is about weaponizing sound to damage computer systems. Nowhere in this publication does it even theorize being about to collect meaningful data from soundwaves hitting a HDD platter. GTFO
