Malware spam: "Delivery status" leads to Locky

This fake financial spam leads to Locky ransomware:

Subject:     Delivery status

Dear Client! Our delivery department could not accept your operation due to a problem with your current account.
In order to avoid falling into arrears and getting charged, please fill out the document in the attachment as soon as possible and send it to us.

In the sample I analysed there was an attachment named document_recipientname.zip (i.e. the first part of the recipient's email address was in the name), containing a malicious javascript with a random name. This particular script (and there are probably many others) attempts to download a component from one of the following locations:

sbdma.com/ri3xnzkaoz
robertocostama.com/qpnst8glsz
kettycoony.com/ahkzls3w
sadhekoala.com/efgqy4tdw
sdwsgs.com/voh7


According to this Malwr analysis, a malicious DLL is dropped with an MD5 of ebf03567c2a907705a026ff0821d8e63 and a detection rate of 6/55. The Hybrid Analysis reveals the following C2 locations:

91.201.202.130/information.cgi [hostname: dominfo.dp.ua] (FLP Anoprienko Artem Arkadevich aka host-ua.com, Ukraine)
95.213.186.93/information.cgi [hostname: djaksa.airplexalator.com] (Selectel, Russia)
188.120.250.138/information.cgi [hostname: olezhkakovtonyuk.fvds.ru] (TheFirst-RU, Russia)
213.32.66.16/information.cgi (OVH, France)

For those Russian and Ukranian networks I would be tempted to block the entire /24 at least, but this is my minimum recommended blocklist:

91.201.202.130
95.213.186.93
188.120.250.138
213.32.66.16

UPDATE

These are additional download locations for this variant (thank you to my usual source):
