Google's Android devices has the feature of #Google Now that let the users to control the search through their voices in Google and also there is a personal assistance available in Applle devices in the name of #Siri.
Both of them are enough to carry out any hack on devices nearby. The only requirement for this hack is that the victim should have a Microphone enabled pair of Headphones inserted into the slot.
A security researcher demonstrated this hack and he stated that the radio signal can be generated to trigger the Personal Assistant silently in any device nearby through the Headphone and Microphones attached.
After the personal assistant has been enabled then the following malicious activities can be carried out
