Smartphones have become a part of our everyday life and many of the details related to our lives are saved in them. In this way, smart speakers and home devices have made a place in our lifestyle, who have answers to every question and with their help, we can control the smart devices installed in the home. Now it has been revealed that these smart speakers can also be hacked and almost all the details related to you can be stolen. According to new research, it can be done only with the help of a laser.

Research by the University of Michigan and the University of Electro-Communications has been published under the name ‘Light Commands: Laser-Based Audio Injection Attacks on Voice-Controllable Systems’. Researchers say that commands can be given remotely to iPhone, Siri, Alexa, Facebook Portal, and Google Home Devices without saying anything and without appearing. With the help of laser, these devices can be tasked by giving commands such as locking, unlocking, starting vehicles, unlocking doors or accessing websites.

Researchers have said that they can be given commands with the help of laser from 360 feet or about 110 meters away from these devices. Since these devices are voice-activated and cannot verify users without getting any voice commands, in such a situation laser attacks can be done easily and many times.

Which takes the help of micro-electro-mechanical systems (MEMS). Any device using this system can be hacked with a laser.
