Attached is a malicious document Leathams Ltd_INV2372039.doc which comes in at least two different versions (VirusTotal [1] [2]). The Malwr analysis for one of those samples shows a download from:


This is similar to a spam run earlier, but now the payload has changed to one with a detection rate of precisely zero (MD5 0d37099eaff9c507c782fd81c715255b). Analysis of this is pending. The payload is the Dridex banking trojan.


Automated analysis [1] [2] shows the executable phoning home to: (Hostpro Ltd, Ukraine)

I strongly recommend blocking traffic to that IP, or the whole /22 in which it resides.
