The message comes in with a number of subjects:
Subject: I love this Carol!
Subject: Santa Said, HO HO HO
Subject: Christmas Email
Subject: The Perfect Christmas
Subject: Find Some Christmas Tail
Subject: Time for a little Christmas Cheer
The body is something similar to:

Thanks Kevin for the initial report.
I recommend that you apply blocks on that domain (merrychristmasdude.com) for both outbound HTTP requests and incoming emails.

The domain appears to be registered through nic.ru and hosted on a fast-flux network of at least 1000 nodes. Like previous Storm waves, the binary changes approximately every 15 minutes; supposedly updating the peer-list used by the P2P network that the bot-net uses for command and control.
