While her presentation at DefCon was her first public vulnerability disclosure, CyFi said she was only a little nervous. An artist, girl scout and downhill skier, she has spoken publically numerous times, usually at art galleries as a member of "The American Show," an underground art collective based in San Francisco. According to her bio on the DefCon Kids Web site, CyFi has had her identity stolen twice.

Rosenblatt points out that the new DefCon Kids programming reflects that "members of the hacking community are getting older and raising families."

DefCon 19 ends Sunday.
