An anonymous reader writes: Two French researchers have discovered a way to use the Siri and Google Now voice assistant software to relay malicious commands to smartphones without the user's consent or knowledge. This method relies on a special hardware rig that can send radio waves to smartphones with earphones plugged into them. The radio waves get picked up by the earphone cable, get transformed into electrical signals and then to software commands. The research is accompanied by a YouTube video as well. Note that this attack, as the article explains, so far relies on some bulky dedicated equipment, and on the attacker being close to the system he wants to disrupt.
