The stats

-300,000+ computers infected
-50% of the spam world wide
-60 billion spam a day

This is considered by some to the be a superbotnet of the 21st century as it even dwarfs the Storm worm by such a large margin that everyone is concentrating on this bad boy because of the fact that Srizbi produces more spam then any of the current botnets that are out there.. As for how this botnet work this quote says it all:

QUOTE
If it's growing, what is it about this botnet that has made it so successful? Srizbi appears to spread by as part of the spam messages it sends, meaning that its lifecycle extends to reproducing itself and not just distributing email. This is not a unique feature, but it could be that it is either evading detection at this stage or tricking people using more sophisticated social engineering.


Which means that any spam that you see in your email account is coming from Srizbi, and I wouldn't be surprise if it has taking over the infamous lottery spam and the money transfer spam as well. It is worth mentioning that they predict that one day Srizbi will calm down just like Storm is, as the Storm worm is taking only 1% of the spam intake at the moment and that started last year though. So one would assume that this bad boy has plenty of growth and I wouldn't be surprise if it caps a million computers by the time it gets dethroned.
