that's why I play on a cheap PC that always runs the fans at max speed

I'm pretty sure it's been demonstrated that you can reconstruct soundwaves from the vibrations of a reflective surface and thereby use a beam of light to spy on a verbal conversation.

same guy who invented the theremin!! (although the thing used radio waves, it wasn’t a laser microphone)

You could probably work around this by changing the fan curve and using an fps cap.

Is it about the literal sound of the GPU fans, or is it electronic noise that's bleeding over into the microphone and not being correctly scrubbed, either because the microphone cable is basically one big antenna or because it causes some sort of interference on the motherboard itself?

[–] YearOfTheCommieDesktop@hexbear.net 14 points 10 months ago (1 children)

probably the latter with the mic cable acting as an antenna

Easier to use a USB mic to avoid it

[–] YearOfTheCommieDesktop@hexbear.net 4 points 10 months ago

yah that might do it

still the point with side channel attacks is less that you can't stop any of them and more that you most likely won't stop all of them, no matter how paranoid you are

[–] YearOfTheCommieDesktop@hexbear.net 12 points 10 months ago

don't think so, fans likely have little to do with it. it's the actual preparatory rendering being done when an object still obscured by a wall enters your fov that creates the interference that is picked up by the mic. I'm guessing a noise gate would mostly eliminate this channel of attack

:fidel-cool: i have no microphone on my gaming PC

shitty setup stays winning

Only useful at LAN which I guess is the point. I'm not sure when I've had access to my opponents's microphone and that wouldn't have been advantageous. My friend got very far in ESEA because the power draw on his system would noticeably increase when people were pushing the single spot he'd hold.

The only time they allow cross team voice chat is during half time or at the very end of the game I think. So basically completely useless lol, unless you’re all on discord playing some unserious hide and seek stuff

[–] omenmis@hexbear.net 5 points 10 months ago

its completely gone now

This just reinforces my belief that computers were a mistake.

Communicating via tin cans and string to protect my kdr in 2024

If anyone gets tripped by the string that goes all the way to New Zealand, it's because I'm gaming with a Kiwi.
