Not really related to java but...

You guys hear about the 17 year old that just used J.avaS.cript to hack into twitter? He made it so that a lot of people were redirected to a Japanese porn site and it affected around 500,000. The boy claims that twitter has had that flaw for 2 years and they didn't bother to patch it, but nobody bothered to hack it... until now. Genius is all I have to say, too bad he didn't re-route his IP because he was tracked right away.
