Researchers from Tokyo and The University of Michigan have published a paper showing that it is possible to hijack voice assistants and issue commands using lasers pointed at the microphone. Commands can be issued from up to 350 feet away by vibrating the diaphragm of the device's microphone to simulate a real voice command. The research team successfully hijacked Google Home/Nest, Echo Plus/Show/Dot, Facebook Portal Mini, Fire Cube TV, EchoBee 4, iPhone XR, iPad 6th Gen, Samsung Galaxy S9 and Google Pixel 2 devices.
