Subject: InvoiceThe name of the sender and the hexadecimal number at the bottom varies. Attached is a randomly-named ZIP file which in the sample I analysed contains a malicious .wsf script beginning with the word "redacted".

The Malwr analysis for the partially deobfuscated script and this Hybrid Analysis show this particular sample downloading from:
83.235.64.44/~typecent/xvsb58
This drops a malicious Locky ransomware binary with a detection rate of 7/55. Analysis of this binary is pending.
UPDATE
Thank you to my usual source for this analysis. The download locations for the various scripts are:
