Malware spam: "This is from the Telephone Company to remind you that your bill is overdue." leads to Locky

This fake financial spam leads to Locky ransomware:

Subject:     Bill overdue
From:     Alexandria Maxwell
Date:     Thursday, 27 October 2016, 9:35

This is from the Telephone Company to remind you that your bill is overdue.

Please see the attached bill for the fine charge.

The sender name varies. Attached is a ZIP file which in the sample I saw was named detailed_bill_a9ec14342.zip containing a malicious script [pastebin] detailed bill C43A9.vbs

The Malwr Report and Hybrid Analysis for that script shows behaviour consistent with Locky ransomware, and my sources (thank you) tell me that the various scripts download from:
