>>It's not just the walls that have ears. It's also the hard drives.
>>Eggheads at the University of Michigan in the US, and Zhejiang University in China, have found that hard disk drives (HDDs) can be turned into listening devices, using malicious firmware and signal processing calculations.
>>For a study titled "Hard Drive of Hearing: Disks that Eavesdrop with a Synthesized Microphone," computer scientists Andrew Kwong, Wenyuan Xu, and Kevin Fu describe an acoustic side-channel that can be accessed by measuring how sound waves make hard disk parts vibrate.
>>"Our research demonstrates that the mechanical components in magnetic hard disk drives behave as microphones with sufficient precision to extract and parse human speech," their paper, obtained by The Register ahead of its formal publication, stated. "These unintentional microphones sense speech with high enough fidelity for the Shazam service to recognize a song recorded through the hard drive." theregister.co.uk/2019/03/07/hard_drive_eavesdropping/
I'm a boomer who jumped on SSD first day of release, no turning back to hdd since then. Get redpilled zoomer.
Jackson Sullivan
There's probably multiple ways to go about it. A modern HDD would have an accelerometer so it can park heads in case of serious vibrations. But it probably doesn't sample fast enough to record usable frequencies. The thing they're using must be the head actuator, which works on the exact same principle as an electromagnetic speaker, and any electromagnetic speaker can also be used as a microphone.
Elijah Diaz
somebody will sell acoustic decouplers put a sock on it
Aiden Gutierrez
This is brand new information! Oh wait, it isn't. There's been projects to collect earthquake data with hard disks in the past.
Dominic Jackson
my seedbox is way too loud for them to record anything.
Isaiah Garcia
>SPINNING RUST BOOMERS BTFO you little shit
THE PROBLEM IS THE F I R M W A R E
Justin Clark
But SSDs don't have read heads or platters to pick up the vibrations. STAY MAD BOOMER
Jonathan Lopez
>But it probably doesn't sample fast enough to record usable frequencies. They thought that about smartphones, too, user, but they were proveded wrong.
Samuel Anderson
THATS NOT THE ISSUE YOU MOTHER FUCKING FAGGOT REEEEEEEEEEEEEEEEEEEE FUCK YOU
Oliver Davis
It's true. I've collected plenty infromation of this homossexual
Easton Hernandez
Using CRT monitors, which don't have microphones, as listening devices has been a thing in the US military since like the 1990s.
Brandon Phillips
Maybe that’s how Facebook is targeting ads of real world conversations while swearing up and down they’re not using the mic on your phone.
Parker Reyes
Are the inherent audio properties of harddisks why FLACs/MP3s sound full and musical when played from an HDD, but flat and brittle when played from an SSD?
Kevin Nguyen
>KRRRRR KRRKRKRK *whirrrr* KRRRRRRRR KRKRKRKKR Yeah okay great spy device
Dylan Collins
One, that's freaking brilliant. Two, dammit!
Jason Brown
>Yeah okay great spy device waaait a second, maybe that's the reason our hard drives fail - they're being used as listening devices!
Evan Rodriguez
If they turned Jow Forums's harddrive into a listening device, what would they hear?
Nathan Smith
intermittent soft sobbing
Josiah James
Dragon dildo slapping sounds.
Jeremiah Kelly
sometimes both at the same time
Lucas Lewis
>They also note that their work may open future research possibilities, such as using a hard disk's read/write head as a crude sounds generator to issue spoken commands to nearby connected speakers like Alexa, Google Home, and Siri. As opposed to using actual speakers. Lmao that's autistic.
Connor Gonzalez
Imagine how much money was wasted on such an useless and redundant research.
Julian Sullivan
>As opposed to using actual speakers. Lmao that's autistic. User's are becoming more aware of the botnet and are disabling speakers, so spies have to find other ways around this.
Joseph Peterson
obviously the rotational velodensity is better for music
Daniel Nelson
You realize those are backdoored too just by nature of being modern right
Ryder Ward
wouldn't a person notice their hdd spinning up weirdly?
James Reyes
You've never had your hard disk spin up when nothing was happening?
Jackson Morris
>an exploit which would be completely impractical in a real world scenario targeting practically deprecated technology
Well done guys. Nice one.
Thomas Sanchez
...not on linux
Cooper Smith
Won't it just hear the whining and clicking sounds of the hard drive and nothing else? Or does this also work when the drive isn't spinning?
Nathan Cruz
>To get Shazam to identify recordings captured through a hard drive, the source file had to be played at 90 dBA. Which is pretty loud. Like lawn mower or food blender loud.
It requires a ridiculously loud audio source to make this thing work.
Brandon Morgan
typical of Jow Forums to be concerned over an impractical proof of concept heh
Thomas Rivera
man, Im sure they will have fun recording me fapping
Jose Flores
