The Sunday NYTimes Magazine section had an article yesterday, about the dangers of wireless networks, and how for $40, with a Palm PDA you could hack many networks.

NYC has several parks set up as wireless networks. (Bryant Park, on 6th Ave, behind the main library is one) any one can sit in the park, and work online with laptop, but as the article makes clear, they do so at their own risk.

the guy found he could pick up wireless networks 2 blocks away with the software. the guy was a network security guy, and he was checking out a clients site, not hacking, but basicly, he had turned his hacking into a career opportunity-- by finding flaws in wireless network security, he could then sell solutions.
