A KAIST led team shows that AI systems can be reverse engineered remotely using emissions that leak during normal operation, without direct intrusion. Instead, the approach listens. Using a small antenna, the researchers captured faint electromagnetic traces from GPUs and rebuilt how the system was designed. It sounds like a heist trick, but the results hold up, and the security implications are immediate. The system, called ModelSpy, collects electromagnetic output produced while GPUs handle...
