That innocent-sounding bird singing out its morning song may not be so innocent after all. According to scientists at Ruhr-Universitaet in Bochum, Germany, manipulated audio waves from the sounds of birds chirping could be used to launch an attack against voice assistants.
According to the researchers, the manipulated audio files are part of what is called an “adversarial attack,” which is designed to confuse the deep neural networks that help artificial intelligence-powered assistants like Apple’s Siri, Google’s Assistant, and Amazon’s Alexa function.
Using the sound of birds chirping — or edited versions of songs or human speech — manipulated in a way that only the microphone on your smart speaker or smartphone can pick up, the attack bypasses detection from human ears and begins meddling with the A.I. assistant. What sounds like a bird’s song could actually be one of these attacks with hidden commands being delivered to your voice assistant of choice. See more...
