It's true that there are lots of white-hat hackers, but there are also lots of black-hat ones, many of them, I gather, associated with criminal organizations -- and as Retric points out, the Internet allows attacks to come from anywhere on the planet. I don't think it's responsible to suggest that people are unnecessarily worried about the problem. (Full disclosure: I work in the computer security industry.)
