Avast changed the router's firmware, took control of a TV set and made it play a Barack Obama speech over and over."Even if you turn off the TV, the router turns the TV back on and the user can't see anything other than the Obama speech," Steckler said, adding that the hacker could then hold the TV for ransom."I know most people, especially Americans, care much more about their TV than they do about their data.
