Sound like the real version of the famous Good Times Virus: Remember that?
But seriously. Right now I'm watching Person of Interest. They regularly do Bluejacking of phones. We know that the NSA can turn on embedded video and audio on computers and listen to your phone when it is "hung up"
I don't see this as a huge stretch.
I've been aware of the capabilities that seem crazy ever since I read (back in the 1990's the ability of someone to understand a voice conversation by bouncing a laser off a window and translating the vibrations made by people talking into words.
WARNING the Good Times Virus will destroy your hard drive. If Good Times is not stopped in time your computer will enter an "nth-complexity infinite binary loop" damaging the processor.
It will scramble any disks that are even close to your computer. It
will recalibrate your refrigerator's coolness setting so all your ice
cream goes melty. It will demagnetize the strips on all your credit
cards, screw up the tracking on your television and use subspace field
harmonics to scratch any CD's you try to play.
It will give your ex-girlfriend your new phone number.. It will drink all your beer and
leave its socks out on the coffee table when there's company coming
over. It will hide your car keys when you are late for work.
