It's an oldie but goodie. Just imagine, your team of blackhat programmers just finished your dank ass botnet and you're about to launch. I imagine a bunch of nerds in an IRC room going like:

Lel. But all joking aside, Kraken was one of the most succesful botnets ever. With an estimated 500k machines infected through IM/SE, when the announcement of it's existence came at the RSA conference between 07/08 the operators took the C&C infrastructure offline and updated their entire botnet, rendering previous research invalid. Very impressive.
Here's an awesome article from the time that really gets into what the botnet was all about.
