Hacker Targets Twitter To Teach Security
A second worm sent out the messages: "Twitter please fix this, regards Mikeyy" and "Mikeyy is done." Mooney told Net News Daily that he had identified a security loophole in Twitter's site about a week ago and decided to "fiddle" with it out of "boredom." Mooney acknowledged that he could go to jail for his actions, but insisted his only intent was to alert Twitter to a programming flaw. (He doesn't mention whether he ever tried to flag the problem simply by contacting Twitter.)
I think this is a perfect example of something not to do. I'm interested to see if they end up filing charges or not... hmmm....
