Laser can be used to simulate a human voice and hack into Google Home and other smart devices

A group of researchers have published results from a shocking experiment that shows how voice controlled smart devices can be operated remotely using targeted laser beams to simulate human speech. The researchers announced Monday that they were able to control a Google Home and command it to remotely open the garage door from a separate building 230 feet away. Also susceptible were Amazon's Echo, Facebook Portal, a range of Android smartphones and tablets, and both iPhones and iPads. The experiments were conducted by a group of scientists from the University of Michigan and The University of Electro-Communications in Tokyo. 'It's possible to make microphones respond to light as if it were sound,' Takeshi Sugarawa, of University of Electro-Communications in Tokyo, told Wired.
