"Invoice_8W20576.htm" is an HTML attachment containing some obfuscated Javascript that connects to kamarovoskorlovo.ru:8080/images/aublbzdni.php which then attempts to download some malicious components from that domain and also serebrokakzoloto.ru:8080/images/jw.php?i=8 . A Wepawet report can be found here and here.

kamarovoskorlovo.ru and serebrokakzoloto.ru are multihomed on several servers (a raw list can be found at the end of the post). You'll notice that Slicehost figures prominently.
