How did a mediagenic hacker like Adrian Lamo get himself bumped last week from a scheduled appearance on the NBC Nightly News with Tom Brokaw?

Perhaps with his impromptu on-camera intrusion into the peacock network’s own computers.

The vagabond hacker known for his drifter lifestyle and his public forays into large and poorly-secured corporate intranets sat down at a Washington D.C. Kinko’s laptop station earlier this month with a freelance NBC news producer to show-off his particular style of hacking — the 21-year-old typically uses little more than an ordinary browser, possessing an eerie knack for finding undocumented Web servers and open proxies at large organizations.
