Malware spam: "Temporarily blocked" leads to Locky

The attachment on this spam email leads to Locky ransomware:

From: "Ambrose Clements"
Subject: Temporarily blocked
Date: Thu, 29 Sep 2016 13:37:53 +0400

Dear [redacted]

this is to inform you that your Debit Card is temporarily blocked as there were unknown transactions made today.

We attached the scan of transactions. Please confirm whether you made these transactions.

 Attached is a ZIP file with a name similar to debit_card_93765d0d7.zip containing a malicious .WSF script with a random name. These scripts (according to my source) download from one of the following locations:

Malware spam: "Scanning" pretending to be from tayloredgroup.co.uk

Despite having what appears to be a Dropbox URL, the link actually goes to another site completely and downloads a .7z archive file containing a malicious VBS script. Attached is another .7z archive file with a slightly different evil VBS script inside.

Detection rates for the scripts are about 13/58 [1] [2]. Automated analysis [3] [4] [5] [6]  shows Locky ransomware attempting to phone home to the following locations:

91.234.35.170/imageload.cgi (FOP Sedinkin Olexandr Valeriyovuch aka thehost.ua, Ukraine)
109.234.35.75/imageload.cgi (McHost.ru / VDSINA, Russia)

McHost is such a well-known purveyor of toxic crap that I recommend you block all of their ranges (plus I guess the related VDSINA ones), or even block the entire Webzilla AS35415. You can find a list of the network ranges here. Also thehost.ua also has a lot of crap and I would lean towards blocking whole network ranges.

Malware spam: "Our shipping service is sending the order form due to the request from your company."

This fake shipping email comes with a malicious attachment:

Subject:     Shipping information
From:     Charles Burgess
Date:     Thursday, 1 September 2016, 9:30

Dear customer,

Our shipping service is sending the order form due to the request from your company.

Please fill the attached form with precise information.

Very truly yours,
Charles Burgess

The sender's name will vary. Attached is a ZIP file with a random hexadecimal name, containing a malicious .js file beginning with a random sequence and endng with _shipping_service.js.

Automated analysis [1] [2] [3] [4] of two samples sees the script downloading from the following locations (there are probably more than this):


joeybecker.gmxhome.de/430j1t
ngenge.web.fc2.com/vs1qc0
mambarambaro.ws/1zvqoqf
timetobuymlw.in/2dlqalg0
peetersrobin.atspace.com/t2heyor1
www.bioinfotst.cba.pl/u89o4

Between those four reports, there are three different DLLs dropped (VirusTotal [5] [6] [7]). This Hybrid Analysis shows the malware phoning home to:

5.34.183.211/data/info.php [hostname: take.cli] (ITL, Ukraine)
212.109.192.235/data/info.php [hostname: take.ru.com] (JSC Server, Russia)

Dear [redacted],

This is to inform that the transaction you made yesterday is declined.

Please look through the attachment for the verification of the card details.

The name of the sender will vary. Attached is a ZIP file (e.g. transaction-details_4688d047f.zip) containing a malicious VBS script (e.g. transaction_details_63EC6F26_PDF.vbs) which looks like this [pastebin].

Good morning petrol.

Attached is the bank transactions made from the company during last month.

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,
Donnie emily

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:

91.234.32.192 (FOP Sedinkin Olexandr Valeriyovuch, Russia)

Malware spam: "Second Reminder - Unpaid Invoice"

This fake financial spam leads to malware:

From:    Janis Faulkner [FaulknerJanis8359@ono.com]
Date:    29 April 2016 at 11:13
Subject:    Second Reminder - Unpaid Invoice

 We wrote to you recently reminding you of the outstanding amount of $8212.88 for Invoice number #304667, but it appears to remain unpaid.
For details please check invoice attached to this mail

Regards,

Janis Faulkner
Chief Executive Officer - Food Packaging Company 

Attached is a ZIP file with a name similar to unpaid_invoice551.zip which contains a randomly-named script. Oddly, most of the script appears to be text copy-and-pasted from the Avira website.

The scripts I have seen download slightly different binaries from the following locations:

cafeaparis.eu/f7yhsad
amatic.in/hdy3ss
zona-sezona.com.ua/hj1lsp
avcilarinpazari.com/u7udssd

VirusTotal detection rates are in the range of 8/56 to 10/56 [1] [2] [3] [4]. In addition to those reports, various automated analyses [5] [6] [7] [8] [9] show that this is Locky ransomware phoning home to:

91.234.32.19 (FOP Sedinkin Olexandr Valeriyovuch / thehost.ua, Ukraine)
83.217.8.155 (Park-web Ltd, Russia)
31.41.44.246 (Relink Ltd, Russia)
89.108.84.155 (Agava Ltd, Russia)
51.254.240.60 (Relink, Russia / OVH, France)

I strongly recommend that you block traffic to:

91.234.32.19

31.41.44.246
89.108.84.155

Malware spam: "FW: Invoice" from multiple senders

This fake financial spam comes from randomly-generated senders, for example:

From:    Britt Alvarez [AlvarezBritt29994@jornalaguaverde.com.br]
Date:    28 April 2016 at 11:40
Subject:    FW: Invoice

Please find attached invoice #342012

Have a nice day

Attached is a ZIP file containing elements of the recipient's email address. In turn, this contains a malicious script that downloads a binary from one of many locations. The ones I have seen are:

http://rabitaforex.com/pw3ksl
http://tribalsnedkeren.dk/n4jca
http://banketcentr.ru/v8usja
http://3dphoto-rotate.ru/h4ydjs
http://switchright.com/2yshda
http://cafe-vintage68.ru/asad2fl
http://minisupergame.ru/a9osfg

The payload looks like Locky ransomware. The DeepViz report shows it phoning home to:

83.217.26.168 (Firstbyte, Russia)
31.41.44.246 (Relink, Russia)
91.219.31.18 (FLP Kochenov Aleksej Vladislavovich / uadomen.com, Ukraine)
51.254.240.60 (Relink, Russia / OVH, France)
91.234.32.19 (FOP Sedinkin Olexandr Valeriyovuch / thehost.ua.  Ukraine)

These two Hybrid Analysis reports [1] [2] show Locky more clearly.

91.219.31.18
51.254.240.60
91.234.32.19

Malware spam: "Attached File" / canon@victimdomain.tld leads to Locky

This spam has a malicious attachment. It appears to come from within the sender's own domain. There is no body text.

From:    canon@victimdomain.tld
Date:    10 March 2016 at 09:02
Subject:    Attached File

In the sample I saw, there was an attachment victimname@victimdomain.tld_07567_273772.zip which contained a randomly-named script with a detection rate of 5/57. Automated analysis [1] [2] shows that this is the Locky ransomware, and it downloads a binary from:

buyfuntees.com/system/logs/7t6f65g.exe

This binary has a detection rate of  just 1/56. Those reports indicate that the malware phones home to:

31.184.196.78 (Petersburg Internet Network Ltd, Russia)
78.40.108.39 (PS Internet Company LLC, Kazakhstan)

There are probably many other download locations and some more C2s as well, I will update this post if I see them.

Reference numbers vary from email to email. Attached is a file with a name similar to ORD137-89653734-2688148.zip which contains a malicious script of which I have seen just a single sample with a detection rate of 5/56. According to this Malwr report, the script downloads a binary from:

mercadohiper.com.br/system/logs/uy78hn654e.exe

That binary has a detection rate of 4/55. According to the Malwr report for the script and this Malwr report for the binary, it phones home to:

31.184.196.75 (Petersburg Internet Network, Russia)
91.219.30.254 (FLP Kochenov Aleksej Vladislavovich, Ukraine)

There are probably other download locations and C2s, I will update this post if I find out what they are.

UPDATE

Some additional C2s from various sources:

78.40.108.39 (PS Internet Company LLC. Kazakhstan)
31.184.196.78 (Petersburg Internet Network, Russia)
91.234.32.192 (FOP Sedinkin Olexandr Valeriyovuch, Ukraine)

Malware spam: "Receipt 103-526" / Receipt.xls

This spam leads to Locky ransomware:

From     rosalyn.gregory@gmail.com
Date     Thu, 29 Sep 2016 21:07:46 +0800
Subject     Receipt 103-526

I cannot tell if there is any body text, however there is an attachment Receipt.xls which contains malicious code [pastebin] that in the case of the sample I analysed downloads a binary from:

opmsk.ru/g76ub76

There will be many other download locations too. Automated analysis [1] [2] shows that this is Locky ransomware phoning home to:

89.108.83.45/apache_handler.php (Agava, Russia)
91.200.14.93/apache_handler.php [hostname: ef4bykov.example.com] (SKS-LUGAN, Ukraine)
xpcwwlauo.pw/apache_handler.php [hostname: vjc.kz] [91.234.33.132] (FOP Sedinkin Olexandr Valeriyovuch aka thehost.ua, Ukraine)

A malicious DLL is dropped with a detection rate of 6/57. Malicious IPs and domains overlap quite a bit with this earlier attack. This version of Locky encrypts files with a .odin extension.

UPDATE - a source indicates these are all the download locations in this attack:

Thank you. Our latest price list is attached. For additional information, please contact your local ITT office.

The sender's name varies, the subject and body text appear to be the same. Attached is a RAR archive that combines some elements of the recipient's email address in it, e.g. CAA30_info_D241AE.rar.

Thanks to analysis from a trusted source (thank you!) it appears that there are several scripts, downloading a binary from one of the following locations:
