Laser Attack on AI speakers
“We show in our experience that a laser beam can control Google Assistance, smart speakers, and Siri.”
Researchers from Dongseo University (department of Computer Engineering) confirm what we already knew – smart devices can be a blessing and a pain. They can do what we ask, or what others ask, will we ever know?
The researchers came up with the idea to use laser commands to trick the AI speakers. A laser is not audible and can come from all sorts of directions and distances. Their experiments are interesting to read (link below): “We show in our experience that a laser beam can control Google Assistance, smart speakers, and Siri. The attacker does not need to make physical contact with the victim’s equipment or interact with the victim; since the attacker’s laser can hit the smart speaker, it can send commands. In our experiments, we achieve a successful attack that allows us to transmit invisible commands by aiming lasers up to 87 m into the microphone.”
