BERKELEY, Calif. — Many people have
grown accustomed to talking to their smart devices, asking them to read a
text, play a song or set an alarm. But someone else might be secretly
talking to them, too.
Over the last
two years, researchers in China and the United States have begun
demonstrating that they can send hidden commands that are undetectable
to the human ear to Apple’s Siri, Amazon’s Alexa and Google’s Assistant.
Inside university labs, the researchers have been able to secretly
activate the artificial intelligence systems on smartphones and smart
speakers, making them dial phone numbers or open websites. In the wrong
hands, the technology could be used to unlock doors, wire money or buy stuff online — simply with music playing over the radio.
A
group of students from University of California, Berkeley, and
Georgetown University showed in 2016 that they could hide commands in
white noise played over loudspeakers and through YouTube videos to get
smart devices to turn on airplane mode or open a website.
