Thanks for the iTunes Gift Card, but, no thanks

The other day I received a note with a file attached:  Gift_Certificate_641.zip.  My email server stripped the payload, and left me with an empty zip file.  Before I examined the .zip, I uploaded it to VirusTotal, but because it was empty, nothing came back.  I would have liked to have seen what it was, but I'm glad the AV is working on the mail server.  I'm sure the headers on the email were spoofed, if the address was even valid in the first place.  But, the mail came from:  "iTunes Store" .  If anyone can tell me what the actual virus/worm was, I'd be curious to know.
