Study Shows Robot Vacuum Cleaners Can Be Hacked to Spy on People
Robot vacuum cleaners use LiDAR (light detection and ranging) sensors to navigate and map the floor plan. By modifying LiDAR sensors on robot vacuum cleaners, hackers can use it for LidarPhone attack and listen to private conservation for extracting sensitive information.
As the robot cleaner maps the floor by pointing lasers at nearby objects such as dustbins, desks, speakers, or even takeaway bags, the researchers were able to obtain the original sound that vibrated on the object. They found that glossy polypropylene bags were the best reflector of sound while glossy cardboard was the worst.
