Researchers at China’s Zhejiang University have demonstrated how attackers can remotely control digital assistants such as Apple’s Siri, Amazon’s Alexa, and Google Now. The technique, which they christened DolphinAttack, can theoretically be used to get devices running always-on voice assistants to spy on users, disconnect from a network, make phone calls, or log into malicious websites. The researchers tested the effectiveness of their technique on a total of 16 voice-controllable systems including Apple’s iPhone, Amazon Echo, Google Nexus, a Lenovo ThinkPad with Microsoft Cortana, and a couple of automobiles.”]
