Editor's Pick “War Games” was the seminal geek hacker movie that inspired many a young cyber sleuth when it debuted in 1983. The movie told the story of how a kid found a back door into a military computer and accidentally set off a nuclear confrontation and launched the careers of actors Ally Sheedy and Mathew Broderick. Twenty five years later, the movie is still credited for creating the public’s impression of the life of hackers. David Scott Lewis, the one-time hacker who was the model for Broderick’s David Lightman character, spoke about the movie on stage on Saturday at the Defcon conference. I first met Lewis in 1994 when one of his friends described him as a “walking encyclopedia.” Now 50, he’s a clean-tech executive living in China and just starting writing the Zero Day Defense blog. I caught up with him again in front of the faux Trevi fountain at Caesar’s Palace in Las Vegas under a cheerful but fake blue sky.
