Your Smart Bulbs Can Be Hacked

Hackers can take full control of a popular model of internet-connected light bulb from as far away as 400 yards, and mess with it by turning it off and on or even bricking it. In a best-case scenario, this is a great way to prank your Internet of Things-loving friends; in a worst case scenario, hackers could theoretically create a worm that spreads through nearby light bulbs and blacks out entire buildings or even neighborhoods.
