If you are using the popular voice assistance products developed by the top technology companies like Apple, Amazon, Google, then this news is for you. Research teams from the University of Michigan and the University of Electro-Telecommunications, Tokyo demonstrated that “attackers can inject remotely heard and unseen commands to these voice assistant devices with the help of laser lights.”
This code-named technique of ‘Light Commands’ allows ‘wrong-purpose commands to be injected into voice-controlled devices’ such as speakers, tablets, and phones. The research team released a demonstration video earlier this week. In this video, it was shown that commands up to the target may be sent through glass windows for a large distance, even in locked rooms.
