Last year, Rachel Tobac went to DEFCON — the well-known hacker's convention held in Las Vegas annually — to try her luck in a competition. The game? Get in a glass booth, and in front of a live audience, call unsuspecting targets and trick them into giving you details about their company; details which, if obtained by the wrong person, could be used in very nefarious ways. It's called Social Engineering Capture the Flag. While it's gaining steam as a fun competition, its aim is to create awareness about the importance of data protection; exposing the ways in which companies put themselves at risk when employees aren't properly trained on data protection. Last year, as a total newcomer to the game, Tobac won. This year, she went back to defend her title. The key to the game? Partly some good acting chops, and a whole lot of Vegas luck.
