       Crazy read: detecting positions of players in Counterstrike by *listening to their GPU over a microphone*https://faculty.cc.gatech.edu/~genkin/papers/lendear.pdf

       @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

       @uint8_t @jbaert the example they give is an odd one. i can't imagine this being useful as the attacker in this scenario, but by recording your own gpu as the camper couldn't you detect when the attacker enters your frustrum? that seems like a more useful example and would work regardless of voice chat or not. perhaps that's already a known attack vector though.

       @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.

       @aeva yeah, with modern cards the coil whine can be *very* audible as well. Intensity changes per viewpoint, too
