I have seen just a single sample of this, named Untitled_14102015_154510.doc and with a VirusTotal detection rate of 7/54. It contains a malicious macro [pastebin] which according to this Malwr report downloads a malicious binary from:

test1.darmo.biz/437g8/43s5d6f7g.exe

There will probably be other versions of the document downloading from the same location. The binary has a VirusTotal detection rate of 1/54. Those two reports plus this Hybrid Analysis indicate network traffic to the following malicious IPs:

199.7.136.84 (Megawire, Canada)
221.132.35.56 (Ho Chi Minh City Post And Telecom Company, Vietnam)
202.69.40.173 (Gerrys Information Technology (PVT) Ltd, Pakistan)
78.47.66.169 (Hetzner, Germany)

The payload is likely to be the Dridex banking trojan.
