Attached is a file ship20150817.zip which in turn contains a malicious executable ship20150817.exe which has a detection rate of 4/56. According to these automated analysis tools [1] [2] the malware attempts to phone home to:

megapolisss006.su/go/gate.php

.SU (Soviet Union) domains are bad news in general, if you can I would recommend blocking traffic to all of them. This domain is hosted on the following IPs:

195.2.88.196 (Zenon N.S.P., Russia)
94.229.22.39 (Bashrtcomm LIR, Russia)
94.229.22.42 (Bashrtcomm LIR, Russia)

You might want to consider blocking:

195.2.88.0/24
94.229.16.0/21

This though is the recommended minimum blocklist:
195.2.88.196
94.229.22.39
94.229.22.42

I am not entirely certain of the payload as the download locations seem to be unreliable.
