Security Researchers at the University of California, in collaboration with researchers from Berkeley University and Georgetown, have devised a method of hacking for violating mobile devices, and more particularly through the use of hidden voice commands embedded in YouTube videos.
To achieve a device violation, the only requirement is to follow a specially designed video, which contains embedded hidden voice commands.
These hidden commands received from digital assistants to mobile user devices, such as Google Now and Siri, which filter out the commands of sounds and other noises and perform. As even the researchers, although the voice commands are utilized to effect the particular type of attack is not understood and perceived by human listeners interpreted, however, as the orders of the devices.
Interesting is also the fact that the hacking users do not have to watch the video from the device, as the breach can also be achieved through the video surveillance from several nearby sources, such as from a PC, laptop, Smart TV, smartphone or tablet.
