The attachment has a random name in the format remit41071396.doc and I have seen three different versions with quite low detection rates [1] [2] [3]. The Malwr reports for these [4] [5] [6] indicate that it has the same behaviour as the spam documented here, dropping a file tsx.exe with an MD5 of fdd95b4cc10b536934486c7d3fdee04f.
