Mysterious Attachment called Crimbo.exe

Would anyone happen to know anything about an attachment called Crimbo.exe??

I can’t find about it at Symantec or McAfee. My wifes company received it, & as soon as someone opened it they noticed that it started randomly propogating itself through the address book. We noticed today that our company received it a couple of days ago & several employees have sent it out to other people in the company, but we don’t see any evidence of it propogating itself.

Does anyone know anything aboutCrimbo.exe????

Thanks in advance.
