Malware spam: "Credit details ID: 87320357" leads to Teslacrypt

So many Teslacrypt campaigns, so little time... I've had to rely on third party analysis on this particular one (thank you!)

Your credit card has been billed for $785,97. For the details about this transaction, please see the ID: 87320357-87320357 transaction report attached.

NOTE: This is the automatically generated message. Please, do not reply. 
Send names, references and attachment names vary. The malicious scripts in the attachment attempt to download from:

giveitallhereqq.com/80.exe?1
washitallawayff.com/80.exe?1


This is Teslacrypt ransomware with VirusTotal detection rates of 1/57 [1] [2]. The malware attempts to phone home to:

198.1.95.93/~deveconomytravel/cache/binstr.php

The download locations for the executable files can all be considered as malicious:

54.212.162.6 (Amazon AWS, US)
212.119.87.77 (Middle East Internet Company Limited, Saudi Arabia)
78.135.108.94 (Sadecehosting, Turkey)

178.18.99.23 (Maginfo JSC, Russia)
31.47.179.11 (Baikal TransTeleCom, Russia)
31.134.39.52 (IRONNET Ltd, Russia)
119.247.218.165 (Hong Kong Broadband Network Ltd, Hong Kong)
113.252.180.39 (Hutchison Global Communications, Hong Kong)
37.115.24.106 (Kyivstar GSM, Ukraine)
5.248.2.179 (Kyivstar GSM, Ukraine)
193.169.134.215 (SDS-Vostok Ltd, Russia)
5.166.207.194 (ER-Telecom Holding, Russia)
46.172.219.246 (Krym Infostroy Ltd, Ukraine)

Out of these, only the first three (for giveitallhereqq.com) appear to be static IPs, the others (for washitallawayff.com) are dynamic and are likely part of a botnet, so blocking the domain might be better.

Recommended blocklist:
54.212.162.6
212.119.87.77
78.135.108.94
