@jbaert Lots of modern #invivo#neurobiology is done like this, conceptually. Swap the GPU for a brain and the microphone for a -scope, and this could be a neat "cell population dynamics of enemy perception in a virtual environment" #calciumimaging (or EEG?) study.
Wow. Start a friendly VoIP call with a target, record the audio, find patterns in their CPU activity (exploiting the fact the CPU's electro-magnetic fields are captured by the target's built-in PC microphone and can be distilled from the acoustic audio source), match the patterns against pre-trained classifier and deduce some of the target's web activity, cryptographic secrets, position within a video game. It is mind-boggling. #cyber#security#research#machinelearning https://faculty.cc.gatech.edu/~genkin/papers/lendear.pdf
“a player in the Counter-Strike online multiplayer game can detect a hidden opponent waiting in ambush, by analyzing how the 3D rendering done by the opponent’s computer induces faint but detectable signals into the opponent’s audio feed.”
@ives@jbaert Well we certainly aren’t taught to run around shooting (you wouldn’t hit anything like that), so I would say that what in games is demeaningly called “camping” is an essential part of military tactics.
@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 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
