In a ballroom in Bally's Vegas casino, kids are lined up on either side of a table with soldering guns melting metal to metal. Their small hands deftly join LED to circuit board, while a few feet away other children are learning the basics of developing. In the back of the room, a group of children and their parents watch two preteen girls give a presentation on the cryptography found in a TV show. This is R00tz Asylum, the kid-friendly portion of the Def Con hacker conference. From the first-timers ripping apart various electronics to see what makes them tick, to the teenage hacker "CyFi," who revealed her first zero-day exploit at age 10, R00tz is exposing children to the world of white-hat hacking to make the future of our digital world a bit safer.
