My colleague Chris Mannon recently came across a file that contains all sorts of Botnet fun and games, along with a fair amount of spam related action into the bargain....and final tie-in to a familiar face. Shall we take a look?

Of course.

I always like to get a look at the file sitting all harmless and stuff on the desktop - don't you? I hope so, because here it is:

That's not all - I mentioned Spam, right? Well, while running, it has the ability to manipulate mail in Outlook (spam, spam, spam, spam) and specifically looks for Opera Mail usernames and passwords.

....yep, it's related to our "good friend" The Storm Worm, because "Get Krackin" is the latest scam to come out of the Storm Stable.

We detect this bundle of joy as DSData.
