(IEEE S&P'23) MagBackdoor: Beware of Your Loudspeaker as Backdoor of Magnetic Attack for Malicious Command Injection
An audio system containing loudspeakers and microphones is the fundamental hardware for voice-enabled devices, enabling voice interaction with mobile applications and smart homes. This paper presents MagBackdoor, the first magnetic field attack that injects malicious commands via a loudspeakerbased backdoor of the audio system, compromising the linked voice interaction system.
