Malware spam: "Unpaid Invoice from Staples Inc., Ref. 09123456, Urgent Notice" leads to Teslacrypt

This fake financial spam is not from Staples or Realty Solutions but is instead a simple forgery with a malicious attachment.

The names, amounts and reference numbers change from email to email. The attachment has the same name of the reference (e.g. invoice_09846839_copy.doc) but despite this I have only seen one version with a VirusTotal detection rate of just 1/55.

According to this Malwr report, the macro in the document downloads a binary from:

iamthewinnerhere.com/97.exe

This appears to be Teslacrypt ransomware and it has a detection rate of 5/53. Unlike some other malware, the domain iamthewinnerhere.com has been registered specifically to host this malware, and is located on:

185.69.152.145 (Hosting Ukraine Ltd, Ukraine)
84.200.69.60 (Ideal-Hosting UG, Germany)


Nameservers are DNS1.SAYMYLANDGOODBYE.IN and DNS2.SAYMYLANDGOODBYE.IN. Other suspect sites on these IPs are:

dns2.auth-mail.ru

According to this Malwr report, it then phones back to these legitimate but hacked domains:
