You might want to move where your smart speaker is located because a new study has found that people can use a simple laser pointer to hack your smart speaker!
According to the study, hackers only need to use a laser to issue commands to a smart speaker instead of spoken words just by aiming the laser at the speaker’s microphone. Apparently smart speakers interpret the laser as if they were sound and interpret it as a command.
Researchers say they have tested this on Google Home devices, Amazon Alexa devices, and Facebook’s Portal Mini, as well as some smartphones including an iPhone XR, a sixth-generation iPad, a Samsung Galaxy S9, and a Google Pixel 2 and they have all had the same problem with what they call “Light Commands.”
