Sochi visitors entering hacking 'minefield' by firing up electronics

NBC reporter Richard Engel worked with a security expert to set up two test computers in order to see just how quickly he'd be attacked when logging onto Russian networks.

Once the two test computers went online, the hacking happened just as fast, Engel said. It took "less than 1 minute [for hackers] to pounce, and in less than 24 hours, they had broken into both of my computers."
