Siri can be silently put to work against you, thanks to a new hack discovered by French security researchers that allows attackers to transmit orders to the digital assistant via a radio.
The hack also works on Google Now and utilizes the headphone cord as an antenna to convert electromagnetic waves into signals that register in iOS and Android as audio coming from the microphone. José Lopes Esteves and Chaouki Kasmie — the two French researchers that discovered the hack — wrote in their paper that hackers could use the attack to get Siri and Google Now to send the phone’s browser to a malware site, or send spam and phishing messages to friends.
“The sky is the limit here,” says Vincent Strubel, the director of their research group at ANSSI. “Everything you can do through the voice interface you can do remotely and discreetly through electromagnetic waves.”
