Siri Hacked from 16 Feet Away Using Radio Waves

French researchers have discovered a way to hack Siri from 16 feet away.
According to an article on Wired:

A pair of researchers at ANSSI, a French government agency devoted to information security, have shown that they can use radio waves to silently trigger voice commands on any Android phone or iPhone that has Google Now or Siri enabled, if it also has a pair of headphones with a microphone plugged into its jack. Their clever hack uses those headphones’ cord as an antenna, exploiting its wire to convert surreptitious electromagnetic waves into electrical signals that appear to the phone’s operating system to be audio coming from the user’s microphone. Without speaking a word, a hacker could use that radio attack to tell Siri or Google Now to make calls and send texts, dial the hacker’s number to turn the phone into an eavesdropping device, send the phone’s browser to a malware site, or send spam and phishing messages via email, Facebook, or Twitter.
 
“The possibility of inducing parasitic signals on the audio front-end of voice-command-capable devices could raise critical security impacts,” the two French researchers, José Lopes Esteves and Chaouki Kasmi, write in a paper published by the IEEE. Or as Vincent Strubel, the director of their research group at ANSSI puts it more simply, “The sky is the limit here. Everything you can do through the voice interface you can do remotely and discreetly through electromagnetic waves.”
