Researchers in the UK claim to have translated the sound of laptop keystrokes into their corresponding letters with 95 percent accuracy in some cases.
That 95 percent figure was achieved with nothing but a nearby iPhone. Remote methods are just as dangerous: over Zoom, the accuracy of recorded keystrokes only dropped to 93 percent, while Skype calls were still 91.7 percent accurate.
In other words, this is a side channel attack with considerable accuracy, minimal technical requirements, and a ubiquitous data exfiltration point: Microphones, which are everywhere from our laptops, to our wrists, to the very rooms we work in.
This is the best summary I could come up with:

To make matters worse, the trio said in their paper that they’ve achieved what they claim is an accuracy record for acoustic side-channel attacks (ASCA) without relying on a language model.
Luckily in this case it’s not power usage, CPU frequencies, blinking lights or RAM buses leaking data unavoidably, but a good old-fashioned problem occurring between the computer and chair that can actually be mitigated somewhat easily.
The researchers note that skilled users able to rely on touch typing are harder to detect accurately, with single-key recognition dropping from 64 to 40 percent at the higher speeds enabled by the technique.
Working among the clacking of phantom keyboards would surely annoy everyone, which is why the researchers suggest only adding the sounds to Skype and Zoom transmissions after they’ve been recording instead of subjecting employees to real-time noisemakers.
Followup research is now going on into using new sources for recordings, like smart speakers, better keystroke isolation techniques and the addition of a language model to make their acoustic snooping even more effective.

Isn’t boffin a derogatory term like “nerd”?
What a dogshit headline.
It can be. Being a boffin, I’m not offended. Up to the individual if they choose to be offended.
Still shitty journalism to refer to researchers publishing their research in that way.
Meh, I wear such labels as badges of honor. I sacrificed a bit along the way to develop knowledge, skills, competence - I’ve earned it. Thanks for acknowledging it.
I also see such things in a humorous light. I mean us “boffins” can be such boffins at times. We can over-focus, get caught up on perfectionism, etc, etc. If’n ya can’t laugh at your own foibles, well, I don’t know what to say.
Maybe a US/UK divide? At least in the UK boffin is relatively inoffensive depending on how it’s used. Eg if I build a fusion reactor in my garden my neighbour might say “wow, look at what this boffin did!” and it would be a complement where boffin is a stand in for a word like genius, only with a tounge in cheek touch of jealousy.
Thinking about it I would say that ‘nerd’ is typically putting someone down for their intelligence or interests, whereas boffin is a light insult while identifying the ‘boffin’ as being smarter than yourself.
I’d be curious how well this approach translates to multi-lingual keyboard layouts. For english users, perhaps theres another benefit to non-QWERTY layouts (e.g. Colemak or Dvorak) after all? … and two factor authentication should remain helpful I presume. Especially physical key methods with no audible characters typed (e.g. Yubikey, Titan, etc.)
Quite scary considering the accuracy and how many open mics everyone is surrounded by without even realizing it. Not to mention if any content creator types their password while live streaming or recording they could get their accounts stolen.
One more reason to switch to a password manager, even though they could still find out the master password…
Probably still have some safety if you’re using two-factor, or have a master key in addition to a password (e.g. 1Password).
Password manager and the LOUDEST MECHANICAL KEYBOARD POSSIBLE you have NO idea what keys I’m pressing with my blues, bitches
Only if you have to type it in to unlock your vault. Now, bear with me.
Bitwarden (maybe others) lets you set a PIN to unlock your vault. Normally, you would think this is a less secure setup, easier to crack with the method outlined in this article. Except with Bitwarden you have to set up the pin in every browser extension and every app install.
Meaning, unless they have access to your device, the PIN to unlock one instance of Bitwarden could be different from the PIN for another. They also don’t have to be strictly 4-digit PINs, either. I highly recommend password managers, but for my money, Bitwarden has all my love.
Disclaimer: I am on no way affiliated with Bitwarden. But I could be if they paid me!
but then I have to remember the PIN for each one of my devices. there should be some kind of app for storing those.
This has been a known attack vector for years, and I wonder how no livestreamer has been (publicly) attacked in this way.
I guess in large part this can be attributed to 2FA, passwords just aren’t worth much by themselves anymore (well I guess if someone is quick enough they can snipe the OTP as well, but streamers are rarely entering their 2FA while streaming since they’re on a trusted device).
In fact the biggest attack vector I’d worry about is the infamous SMS 2FA, which is actually 1FA for password resets, which is actually 0FA “yes dear phone operator I am indeed Mister Beast please move my phone number to this new SIM”.
Idk how it works with non-NVIDIA GPUs but get Nvidia Broadcast or an equivalent. Its a life saver.
It doesn’t do a very good job of removing my keyboard noise for some reason, and it makes my voice sound noticably worse 😔
