Malware spam: "Sent from my Samsung device" leads to Locky

This rather terse spam has a malicious attachment:

From:    Ila
Date:    18 July 2016 at 13:01
Subject:    scan0000511

Sent from my Samsung device
The sender and subject vary, but the subject seems to be in a format similar to the following:

scan0000511
SCAN000044
COPY00002802


Attached is a .DOCM file with the same name as the subject. Analysis by another party (thank you!) shows the macros in the document downloading from one of the following locations:

The payload is Locky with a detection rate of 4/53. It phones home to:

77.222.54.202 (SpaceWeb CJSC, Russia)
91.240.86.221 (JSC Server, Russia)


That's a subset of the IPs found here, so I recommend you block the following IPs:

77.222.54.202
91.240.86.221
176.111.63.51
209.126.112.14
