Chinese researchers detect smartphone app usage via leaked radio signals

By PulseAugur Editorial · [1 sources] ·

Researchers at the People's Public Security University of China have developed a novel non-contact forensic technique that can identify smartphone applications and user actions by analyzing faint electromagnetic signals. This method works even when a phone is offline, in flight mode, encrypted, or locked, offering a potential tool for digital forensics and investigations. The technique was successfully tested on an iPhone 15 Pro, Xiaomi 15 Pro, and Oppo Reno 13. AI
