David Kirkpatrick talking about Parker’s youth:
The teenager had been sitting in the family den, all night, drilling deeply into the bowels of a Fortune 500 company, which he refuses to name. Back then he had a hobby, he says, of hacking into different sorts of organizations, keeping a file of .com, .edu, .mil, and .gov Internet domains he had penetrated in various countries around the world. His goal was to break into one of each type in a laundry list of countries. He claims that once inside he usually alerted the system administrator—from his or her own e-mail—to vulnerabilities he had discovered.
A great read.
