Malware spam: "Bank account record" leads to Locky

This fake financial spam leads to malware:

Subject:     Bank account record

Good morning,

Did you forget to finish the Bank account record?
Read the attachment and let me know if there is anything I didn't make clear.

Yours sincerely,
Stephen Ford

The sender will vary from email to email, but the "From" name is always consistent with the one in the email. Attacked is a ZIP file with a random hexadecimal number which in the sample I am looking at contains a malicious .wsf script starting with the words "account record" (sample here).

According to the Hybrid Analysis on that script and Malwr report on a partly deobfuscated version the script downloads a binary from:

oleanderhome.com/q59ldt5r

This dropped binary has a detection rate of 5/55 and is presumably Locky ransomware, but automated analysis is inconclusive [1] [2].

The is also traffic to kassa.p0.ru which is more of a puzzle and doesn't look particularly malicious. I don't know if that is common to all scripts, but it might be worth looking out for in your traffic logs.

If I get more information on this I will post it here.

UPDATE

My trusted source (thank you) gives the following download locations:
