There is a new hardware hack floating through the hackosphere. I am not talking about another angelic checkm8 bootrom exploit. I’m talking about a voice assistant laser beam hack. I can’t believe I just typed that. A laser beam shinned into a microphone of a smart device can control its voice assistant has been found by University of Electro-Communications in Tokyo and the University of Michigan.
This hack, dubbed Light Commands, can control your device’s voice assistant from up to 361ft (110m). And it doesn’t matter what device it is , Google, Samsung, or even Amazon. This laser hack uses lasers to “attack” the Microelectro-Mechanical Systems (MEMS) microphones on the devices. To change what is being said to the voice assistant all they have to do is change the amplitude of a laser light going into the microphone.
