Seems the making of a science fiction movie, but it's not. Voice search has become the latest hack. ANSSI researchers, a French government agency devoted to information security, have found the can use radio waves to silently trigger voice commands on any Android phone or iPhone that has Google Now or Siri-enabled. That's if the smartphone also has a pair of headphones with a microphone plugged into its jack. While there are a lot of ifs, the headphone's cord is used 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.
