WebA number of recent works have explored side-channels on smart devices for recording sounds with-out permission. This paper presents LidarPhone, a novel acoustic side-channel attack through the lidar sensors equipped in popular commodity robot vacuum cleaners. WebAs you can understand from the name, the attack relies on the use of built-in lidar, which is used to navigate in space. In fact, a potential attacker can use lidar and its laser as a laser microphone. Laser microphones are often used by special services, especially if the recording needs to be made from a distance. denver ports of call
