The attachment has the same reference number as the subject, and there are at least five different versions (VirusTotal results [1] [2] [3] [4] [5]).

Analysis of the documents is pending, but this is likely to be the Dridex banking trojan.

UPDATE 1

Hybrid Analysis of some of the samples [1] [2] shows some download locations:

146.120.89.92/volkswagen/bettle.php
109.234.34.164/volkswagen/bettle.php


Those IPs belong to:

146.120.89.92 (Ukrainian Internet Names Center LTD, Ukraine)
109.234.34.164 (McHost.Ru Inc, Russia)


This is actually an executable with a detection rate of 4/53. The purpose of this executable is unknown, but it is certainly malicious. Analysis is still pending.

UPDATE 2

This Threat Expert report and this Hybrid Analysis both report traffic to a presumably hacked server at:

104.131.59.185 (Digital Ocean, US)

Recommended blocklist:
104.131.59.185
146.120.89.92
109.234.34.164
