The spam comes from different senders with a different hexadecimal number in it. Attached is a ZIP file with a random name, containing a malicious .wsf script. Analysis of a sample shows the script download from:

beauty-jasmine.ru/6dc2y

There will be many more download locations in addition to that. It drops an executable which appears to be Locky ransomware with a detection rate of 7/55. Analysis of this payload is pending, however the C2 servers may well be the same as found here.

UPDATE

The C2 locations for this variant are:
