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!)

Subject:    Credit details ID: 87320357

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/69.exe?1
washitallawayff.com/69.exe?1
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:

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.

Dear Customer,

Despite our constant reminders, we would like to note that the mentioned debt #85533 for $826,87 is still overdue for payment.

We would appreciate your cooperation on this case and ask you to make the payment as soon as possible.

Unless the full payment is received by April 1st, 2016 this case will be transferred to the debt collection agency, will seriously damage your credit rating.

These appear [1] [2] to download a malicious binary from one of the following locations:

ohelloguyff.com/70.exe
ohelloguyzzqq.com/85.exe?1

Of these, only the 85.exe download is working for me at the moment which is Teslacrypt ransomware. This has a detection rate of just 1/56.

Malware spam: "Urgent Notice # 78815053" leads to Teslacrypt

This spam comes from random senders, and has random references, dollar amounts and attachment names:

From:    Donnie emily
Date:    12 March 2016 at 14:01
Subject:    Urgent Notice # 78815053

Dear Customer!

According to our data you owe our company a sum of $452,49. There are records saying that you have ordered goods in a total amount of $ 452,49 in the third quarter of 2015.

Invoice has been paid only partially. The unpaid invoice #78815053 is enclosed below for your revision.

We are writing to you, hoping for understanding and in anticipation of the early repayment of debt.

Please check out the file and do not hesitate to pay off the debt.

Otherwise we will have to start a legal action against you.

Regards,

Attached is a randomly-named ZIP file, in the sample I have seen they begin with:

• letter_
• confirm_
• access_
• unconfirmed_operation_
• operation_
• details_

..plus a random number. There may be other formats. Inside is a malicious script beginning with:

• details_
• post_
• mail_

..plus a random string of characters. I have seen six versions of this script, I do not know how many there are in total. VirusTotal results show detection rates between 4 and 7 out of 57 [1] [2] [3] [4] [5] [6] and automated analysis tools [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] show the script attempting to download a binary from:

bonjovijonqq.com/69.exe?1
bonjovijonqq.com/80.exe?1

This is Teslacrypt ransomware, although it is possible that some variants of this message may drop Locky. Both these binaries are slightly different (VirusTotal results [19] [20]) and they appear to phone home to:

vtechshop.net/wcspng.php
sappmtraining.com/wp-includes/theme-compat/wcspng.php
shirongfeng.cn/images/lurd/wcspng.php

It also attempts to contact the domain multibrandphone.com but that was not resolving at the time of analysis. It also appears to phone home to:

31.184.196.78 (Petersburg Internet Network Ltd, Russia)
91.234.32.192 (FOP Sedinkin Olexandr Valeriyovuch, Russia)

The domain bonjovijonqq.com is purely malicious and is hosted on the following IPs:

I have seen only one sample of this spam with an attachment with a somewhat interesting name of C:\\Users\\HOLLY~1.HUM\\AppData\\Local\\Temp\\Inv_107666_from_DATANET.CO..xls which saves on my computer as C__Users_HOLLY~1.HUM_AppData_Local_Temp_Inv_107666_from_DATANET.CO..xls. This contains this malicious macro [pastebin] and has a VirusTotal detection rate of 3/55.

According to this Malwr report and this Hybrid Analysis the XLS file downloads a malicious binary from :

encre.ie/u5y432/h54f3.exe

There will probably be other versions of this document downloading from other locations too. This has a VirusTotal detection rate of just 1/55 and that report plus this Malwr report  indicate malicious network traffic to:

162.208.8.198 (VPS Cheap, US / Sulaiman Alfaifi, Saudi Arabia)
94.73.155.12 (Cizgi Telekomunikasyon Anonim Sirketi, Turkey)
78.47.66.169 (Hetzner, Germany)

The payload is almost definitely the Dridex banking trojan.

Malware spam: "Sales Invoice OP/I599241 For ANDSTRAT (NO.355) LTD" / "orders@kidd-uk.com"

This fake financial spam is not from James F Kidd, but is instead a simple forgery with a malicious attachment:

From:    orders@kidd-uk.com
Date:    30 November 2015 at 13:42
Subject:    Sales Invoice OP/I599241 For ANDSTRAT (NO.355) LTD

 Please see enclosed Sales Invoice for your attention.

 Regards from Accounts at James F Kidd
 ( email: accounts@kidd-uk.com )

I have seen a single copy of this spam with an attachment invoice574206_1.doc which has a VirusTotal detection rate of 3/55.

This Malwr report indicates that in this case there may be an error in the malicious macro [pastebin]. The Hybrid Analysis report is inconclusive. This document is presumably attempting to drop the Dridex banking trojan.

UPDATE

I have received two more samples, one names invoice574206/1.pdf and the other invoice574206/1.doc. Both are Word documents (so the one with the PDF extension will not open). The VirusTotal detection rates are 7/54 and 4/55. One of these two also produces an error when run.

The working attachment (according to this Malwr report and Hybrid Analysis report) downloads a malicious binary from:

The attachment is named 988271023-PRCL.doc and so far I have come across three different versions of this (VirusTotal results [1] [2] [3]), containing a malicious macro like this [pastebin] which according to these Hybrid Analysis reports [4] [5] [6] downloads a malware binary from the following locations:
