Yesterday I saw several spam runs similar to this coming from Dridex botnet 120. There are many, many variations of the attachment although I do not believe that they are uniquely-generated.

The three samples I have sent for analysis so far has VirusTotal detection rates of 2/55 [1] [2] [3] and the Malwr reports [4] [5] [6] show an initial communication with:

193.201.227.12/ideal/jenny.php
91.223.88.205/ideal/jenny.php
176.103.62.108/ideal/jenny.php

These IPs belong to:

176.103.62.108 (Ivanov Vitaliy Sergeevich, Ukraine)
91.223.88.205 (Private Person Anton Malyi, Ukraine)
193.201.227.12 (PE Tetyana Mysyk, Ukraine)


I note that 91.223.88.204 also hosts some bad things.. and the entire 176.103.48.0/20 block has a history of evil-ness [1] [2] [3].

Note that there are probably other download locations. Check back later if you are interested.

These malicious documents drop a binary geroin.exe which has a detection rate of 3/54. The Malwr report for this shows it phoning home to:

78.47.119.93 (Hetzner, Germany)
