The attachment is called HMRC_TAX_Notice_rep.zip which in turn contains a malicious exectuable HMRC_TAX_Notice_rep.scr which has a VirusTotal detection rate of 5/51.

According to the Malwr report, the malware makes a download from the following locations hosted on 67.205.16.21 (New Dream Network, US):

Subsequent communications are made with aulbbiwslxpvvphxnjij.biz on the familiar looking Linode IP of 50.116.4.71, and also qkdapcqinizsczxrwaelaimznfbqq.biz on another Linode IP of 178.79.178.243. An attempt it also made to connect to hzdmjjneyeuxkpzkrunrgyqgcukf.org which does not resolve.

One odd thing in the Anubis report is this dialog box entititled "seconddial" and containing the word "diminutiveness".

I don't know what that is.. it reminds me of Hatefulness/Hatefulness though :)
