@jbaert thanks for sharing!

@jbaert Now this is computer engineering.

@jbaert information leakage is hard to prevent! who knew‽

Thanks for sharing, this is a very nice piece of work.

@jbaert meanwhile gamers

@jbaert my brain autocorrected 'positions' to 'positrons' and i gave birth to several live kittens.

@jbaert I had an NSA friend whose job was mostly coming up with wacky stuff like this with gadgets, game consoles, home automation, you name it. What a job.

@jbaert is it really common to be on voice chat with everyone? I haven’t played CS probably the past 10 years, but we only talked with our team, and even then often with PTT

@jbaert wow! I never had access to this but was pretty good at listening and was able to identify where people was. This is crazy!

@jbaert you could also just look at your gpu activity in task manager but , i guess going through the trouble of listening to the mic makes a better paper.

@jbaert I would have needed that 20 years ago

@jbaert some people have too much time on their hands

@jbaert@mastodon.social alt: Figure 15 from the paper, an illustration with stick figures. Counter-Strike camper detection via side channel leakage: when the attacker is within the camper's frustum, rendering on the camper's computer results invisible differences in the spectrogram. Thus, by entering the frustum and examining the signal, the attacker can detect the ambush, while neither seeing nor being seen by the camper.

@jbaert This reminds me of that time that MIT researchers figured out how to reverse engineer video of a chip bag to extract the vibration and reconstruct the audio of a conversation https://wapo.st/3tX7goi

@jbaert I'm not even remotely surprised given how much emi GPUs give off. I've worked with some where I could hear the general load on my headphones.

@jbaert Aah, camping, is there anything more gratifying? 😎 #guiltypleasure
