Malware spam: "Delivery Confirmation: 0068352929" / "ACUVUE_DEL [ship-confirm@acuvue.com]"

This fake financial spam does not comes from Acuvue, but is instead a simple forgery with a malicious attachment:

Date     Tue, 03 Nov 2015 12:26:17 +0200
Subject     Delivery Confirmation: 0068352929

PLEASE DO NOT REPLY TO THIS E-MAIL.  IT IS A SYSTEM GENERATED MESSAGE.

Please contact us if there are any questions or further assistance we can provide

Attached is a file Advance Shipping Notification 0068352929.DOC which my sources (thank you, btw) say comes in four different versions, although I have only seen three (VirusTotal results [1] [2] [3], Hybrid Analysis results [4] [5] [6])  containing a macro that looks like this [pastebin]. The download locations are:

builders-solutions.com/45gce333/097j6h5d.exe

www.prolococopparo.it/45gce333/097j6h5d.exe

This malicious binary has a VirusTotal detection rate of 6/54. That VT report and this Hybrid Analysis report show network communications to the following IPs:

128.199.122.196 (Digital Ocean, Singapore)
75.99.13.123 (Cablevision, US)
198.74.58.153 (Linode, US)
221.132.35.56 (Ho Chi Minh City Post and Telecom Company, Vietnam)

The payload is most likely to be the Dridex banking trojan.

Recommended blocklist:
128.199.122.196
75.99.13.123
