Dear webmaster,

Please review the attached corrected annual report.

Yours faithfully
Joey Cox
The name of the sender will vary. Attached is a ZIP file with a random name, containing a malicious .WSF script beginning with "annual report". This attempts to download Locky ransomware from one of the following locations (thank you to my usual source for analysis):

The dropped binary then attempts to phone home to:

91.230.211.139/upload/_dispatch.php (Optizon Ltd, Russia) [hostname evradikfreeopti.ru]
37.139.30.95/upload/_dispatch.php (Digital Ocean, Netherlands) [hostname belyi.myeasy.ru]
91.219.29.48/upload/_dispatch.php (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)

The host for that last one comes up over and over again, it's time to block that /22..

Recommended blocklist:
91.230.211.139
37.139.30.95
91.219.28.0/22
