The potential for digital-home assistants like Amazon Alexa to infringe on user privacy by making and saving voice recordings of them is already widely known. According to new research by a team of researchers from the University of Cambridge, microphones on digital assistants are sensitive enough to record what someone is typing on a smartphone to steal PINs and other sensitive info. The researchers constructed an attack in which they used this capability to identify PINs and text typed into smartphones. Given just 10 guesses, five-digit PINs can be found up to 15 percent of the time, and text can be constructed with 50 percent accuracy.
