Malware spam: "Tracking data" leads to Locky

This spam has a malicious attachment leading to Locky ransomware:

From:    Loretta Gilmore
Date:    20 September 2016 at 08:31
Subject:    Tracking data


Good afternoon [redacted],

Your item #9122164-201609 has been sent to you by carrier.
He will arrive to you on 23th of September, 2016 at noon.



The tracking data (4fec25a8429fd7485c56c9211151eb42d59b57abf402cc363bc635) is attached.


The sender's name and reference numbers vary. Attached is a randomly named .ZIP file containing a malicious .js script named in the format tracking data ~C503090F~.js (the hexadecimal number is random) plus a junk file with a single-letter name.

Analysis of the attachments is pending.

UPDATE

Hybrid Analysis of various samples [1] [2] [3] [4] shows the script downloading from various locations:

akinave.ru/ckk7y
solenapeak.com/ha4n2
vetchsoda.org/uemmdt
akinave.ru/1e11lhrk


All of these are hosted on:

178.212.131.10 (21 Century Telecom Ltd, Russia)
95.173.164.205 (Netinternet Bilisim Teknolojileri AS, Turkey)


The malware then phones home to the following locations:

91.223.88.205/data/info.php (Anton Malyi aka conturov.net, Ukraine)
176.103.56.105/data/info.php (Ivanov Vitaliy Sergeevich aka xserver.ua, Ukraine)
46.38.52.225/data/info.php (TCTEL, Russia)
195.64.154.202/data/info.php (Ukrainian Internet Names Center, Ukraine)
kixxutnpikppnslx.xyz/data/info.php  [91.223.88.209] (Anton Malyi aka conturov.net, Ukraine)

A DLL is dropped with a detection rate of 13/57.

Malware spam: "Unable to deliver your item, #000179376" / "FedEx International Ground" leads to ransomware

This fake FedEx email has a malicious attachment.

From:    FedEx International Ground [terry.mcnamara@luxmap.com]
Date:    2 August 2016 at 18:53
Subject:    [REDACTED], Unable to deliver your item, #000179376

Dear [Redacted],

This is to confirm that one or more of your parcels has been shipped.
Please, open email attachment to print shipment label.

Thanks and best regards,
Terry Mcnamara,
Support Manager.
Attached is a ZIP file FedEx_ID_000179376.zip which contains a malicious script FedEx_ID_000179376.doc.js which is highly obfuscated but which becomes clearer when deobfuscated. This Hybrid Analysis on the sample shows that the script downloads ransomware from opros.mskobr.ru but a quick examination of the code reveals several download locations:

opros.mskobr.ru
alacahukuk.com
www.ortoservis.ru
aksoypansiyon.com
samurkasgrup.com


Three of those domains are on the same IP (77.245.148.51), so we can assume that the server is completely compromised. If we extend that principle to the other servers then you might want to block traffic to:

195.208.64.20 (ROSNIIROS, Russia)
77.245.148.51 (Bilisim Teknolojileri Yazilim San. Tic. Ltd. Sti., Turkey)
5.101.153.32 (Beget Ltd, Russia)


A couple of binaries are dropped onto the system, a.exe (detection rate 2/53) [may not be malicious] and a2.exe (detection rate 7/53).

The payload seems to be Nemucod / Crypted or some related ransomware.

Malware spam: "Per E-Mail senden: DOC0000329040"

This German-language spam comes with a malicious attachment. It appears to come from the victim themselves, but this is just a simple forgery.

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!)
From:    Ladonna feather
Date:    14 March 2016 at 14:50
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

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.

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:

..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/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

Malware spam: "GreenLand Consulting – Unpaid Issue No. 58833"

This fake financial spam comes with a malicious attachment:

From:    Jennie bowles
Date:    10 March 2016 at 12:27
Subject:    GreenLand Consulting – Unpaid Issue No. 58833

Dear Client!

For the third time we are reminding you about your unpaid debt.

You used to ask for our advisory services in July 2015, the receipt issued to you was recognized in our database with No. 58833. But it has never been paid off.

We enclose the detailed bill for your recollection and sincerely hope that you will act nobly and responsibly.

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

Respectfully,
Jennie bowles

Details on the individual emails vary. Attached is a ZIP file which contains one of a variety of malicious scripts (sample VirusTotal results [1] [2] [3] [4]). According to these Malwr reports [5] [6] [7] these scripts attempt to download a malicious binary from the following locations:

http://hellomississmithqq.com/69.exe?1
http://hellomississmithqq.com/80.exe?1
http://mommycantakeff.com/69.exe?1

74.117.183.252 (WZ Communications, US)
91.243.75.135 (Martin Andrino Ltd, Netherlands)


This Malwr report and this Hybrid Analysis shows communications with:

91.195.12.131 (PE Astakhov Pavel Viktorovich, Ukraine)
149.154.157.14 (EDIS, Italy)
151.236.14.51 (EDIS, Netherlands)

78.40.108.39 (PS Internet Company LLC, Kazakhstan)
178.162.214.146 (Leaseweb, Germany)


The two executables seem different (VirusTotal results [1] [2]). It looks like it might be dropping both ransomware (Teslacrypt perhaps) and Dridex (banking trojan) alternately.

These domains are also associated with some of the IPs. Consider them all to be evil:

Malware spam: "Order Delay - Package Ref. 30432839"

This spam comes with a malicious attachment. The name of the sender and the reference number will vary from message to message.

From:    Lorna trevor-roper [trevor-roperLorna54235@cable.net.co]
Date:    3 March 2016 at 17:28
Subject:    Order Delay - Package Ref. 30432839


Respected Customer,

The delay of your parcel ref. # 30432839 cannot be controlled due to the unstable weather conditions in our region.

We are doing everything we can to arrange the best shipping time for your package.

Please check the information on your purchase in the attached file. There your will also find the info on the new delivery time.

Sincerely,
Sales Department Manager
Lorna trevor-roper

Des Moines, IA 27222

So far I have seen three samples, with attachments named in the format Invoice_ref-30432839.zip containing a malicious script starting with invoice_ and then having some variable elements in it. These have detection rates of 3/55 or so [1] [2] [3] and which the Malwr reports [4] [5] [6] indicate attempt to GET a binary from one of the following locations:

isthereanybodyqq.com/69.exe?1
isthereanybodyqq.com/80.exe?1
ujajajgogoff.com/69.exe?1
ujajajgogoff.com/80.exe?1

Data is then POSTed to:

dustinhansenbook.com/wstr.php
agri-distribution.net/wstr.php
onegiantstore.com/wp-includes/theme-compat/wstr.php

The VirusTotal reports for the dropped binary [1] [2] indicate Ransomware, but those Malwr reports look more like the Dridex banking trojan. Either way it is Nothing Good.

The download locations are interesting, hosted on the following IPs:

78.135.108.94 (Sadecehosting, Turkey)
162.211.67.244 (Secure Dragon LLC, US)


The following domains are either hosted on these IPs or use them as namesevers. They all look highly suspect and worthy of futher analysis:

ohelloweuqq.com
ujajajgogoff.com
ohellohowru.ws
ujajajgogo.ws
gangthatgirlfast.ws

Malware spam: "Lattitude Global Volunteering - Invoice - 3FAAB65"

This fake financial spam comes from random senders and with different reference details. It does not come from Lattitude Global Volunteering but is instead a simple forgery with a malicious attachment.

Lattitude Global Volunteering is a UK registered international youth development charity (No. 272761), a company limited by guarantee (No. 01289296) and a member of BOND (British Overseas NGOs for Development).
I have personally only seen two samples so far with detection rates of 2/55 [1] [2] . These two Malwr reports [3] [4] plus some private sources indicate that the attachments download from the following locations:

31.131.20.217/shifaki/indentification.php
185.125.32.39/shifaki/indentification.php
5.34.183.41/shifaki/indentification.php
5.149.254.84/shifaki/indentification.php


This is characteristic of spam sent by the Dridex 120 botnet. All the IPs can be considered to be malicious and should be blocked.

31.131.20.217 (PE Skurykhin Mukola Volodumurovuch, Ukraine)
185.125.32.39 (Sembol Internet Hizmetleri ve Dis Ticaret Ltd, Turkey)
5.34.183.41 (ITL Company, Ukraine)
5.149.254.84 (Fortunix Networks, Netherlands)


A file kfc.exe is dropped onto the target system which has a detection rate of 6/52 and an MD5 of 8cfaf90bf572e528c2759f93c89b6986. Those previous Malwr reports indicate that it phones home to a familiar IP of:

Malware spam: "Invoice Attached" / "Accounting Specialist| Bank of America, N.A., Cabot Oil & Gas Corp."

This fake financial spam has a malicious attachment:

From:    Ernestine Harvey
Date:    15 December 2015 at 11:34
Subject:    Invoice Attached

Good morning,

Please see the attached invoice and remit payment according to the terms listed at the bottom of the invoice. If you have any questions please let us know.

Thank you!

Mr. Ernestine Harvey
Accounting Specialist| Bank of America, N.A., Cabot Oil & Gas Corp.
The sender name varies randomly, except in the email they are all signed "Mr." even if they have female names, for example:

Mr. Colleen Sheppard
Mr. Joel Small
Mr. Esther Gates
Mr. Devin Joyce
Mr. Todd Robertson

The attachments are named in the format invoice_12345678_scan.doc - the filenames are randomly-generated and indeed every attachment seems to be unique. Typical VirusTotal detection rates are around 3/54, and the macro looks something like this.

An analysis of five of the attachments [1] [2] [3] [4] [5] shows attempted downloads from:

modern7technologiesx0.tk/x1656/dfiubgh5.exe
forbiddentextmate58.tk/x1656/ctruiovy.exe
temporary777winner777.tk/x1656/fdgbh44b.exe
former12futuristik888.tk/x1656/fdgjbhis75.exe


Note that these are all .TK domains.. and they are all hosted on exactly the same server of 31.184.234.5 (GTO Ltd, Montenegro). A look at VirusTotal's report for that IP gives another malicious domain of:

servicexmonitoring899.tk

I would suggest that the entire 31.184.234.0/24 range looks pretty questionable.

Anyway, the downloaded binary has a VirusTotal detection rate of 4/55 and the comments indicate that rather surprisingly this is the Nymaim ransomware. The Hybrid Analysis indicates network traffic to xnkhfbc.in on 200.195.138.156 (Szabo & Buhnemann, Brazil). But in fact that domain seems to move around a lot and has recently been seen on the following IPs:

41.224.12.178 (Orange Tunisie Internet, Tunisia)
51.255.59.248 (OVH, France)
78.107.46.8 (Corbina Telecom, Russia)
95.173.163.211 (Netinternet, Turkey)
118.102.239.53 (Dishnet, India)

200.195.138.156 (Szabo & Buhnemann Ltda, Brazil)
210.150.126.225 (HOSTING-NET, Japan)


There are a bunch of bad domains associated with this malware but the only other one that seems to be active is oxrdmfdis.in.

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:

Attached is a file CAR014 151238.doc which comes in at least two different versions with a VirusTotal detection rate of 3/55 for both [1] [2]. According to these Malwr reports [3] [4] the macro in the document downloads a file from one of the following locations:

data.axima.cz/~krejcir/6543f/9o8jhdw.exe


This binary has a detection rate of 3/54. The Malwr report for that file shows that it phones home to:

There are other bad IPs in the 94.73.155.8 - 94.73.155.15 range, so I strongly recommend that you block all traffic to 94.73.155.8/29.

These two Hybrid Analysis reports [1] [2] also show malicious traffic to the following IPs:

89.248.99.231 (Interdominios S.A., Spain)

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:

bjdennehy.ie/~upload/89u87/454sd.exe

This has a VirusTotal detection rate of 3/54. Automated analysis tools [1] [2] [3] [4] show malicious traffic to:

Malware spam: "INTUIT QB" / "QUICKBOOKS ONLINE [qbservices@customersupport.intuit.com]" leads to ransomware

This fake Intuit QuickBooks spam leads to malware:

From:    QUICKBOOKS ONLINE [qbservices@customersupport.intuit.com]
Date:    30 November 2015 at 10:42
Subject:    INTUIT QB


As of November 5th, 2015, we will be updating the browsers we support. We encourage you to upgrade to the latest version for the best online experience. Please proceed the following link, download and install the security update for all supported browsers to be on top with INTUIT online security!

InTuIT. | simplify the business of life

© 2015 Intuit Inc. All rights reserved. Intuit and QuickBooks are registered trademarks of Intuit Inc. Terms and conditions, features, support, pricing, and service options subject to change without notice. 
The spam is almost identical to this one which led to Nymaim ransomware.

In this particular spam, the email went to a landing page at updates.intuitdataserver-1.com/sessionid-7ec395d0628d6799669584f04027c7f6 which then attempts to download a fake Firefox update

This executable has a VirusTotal detection rate of 3/55, the MD5 is 592899e0eb3c06fb9fda59d03e4b5b53. The Hybrid Analysis report shows the malware attempting to POST to mlewipzrm.in which is multihomed on:

89.163.249.75 (myLoc managed IT AG, Germany)
188.209.52.228 (BlazingFast LLC, Ukraine / NForce Entertainment, Romania)
95.173.164.212 (Netinternet Bilgisayar ve Telekomunikasyon San. ve Tic. Ltd. Sti., Turkey)


The nameservers for mlewipzrm.in are NS1.REBELLECLUB.NET and NS2.REBELLECLUB.NET which are hosted on the following IPs:

210.110.198.10 (KISTI, Korea)
52.61.88.21 (Amazon AWS, US)


These nameservers support the following malicious domains:

exstiosgen.com
ecestioneng.com
densetsystem.com
deseondefend.com
xonstensetsat.com
dledisysteming.com
thecertisendes.com
georgino.net
tangsburan.net
rebelleclub.net
helpagregator.net

The download location uses a pair of nameservers, NS1.MOMEDEFER.PW and NS1.PRIZEBROCK.PW. If we factor in the NS2 servers as well, we get a set of malicious IPs:

5.135.237.209 (OVH, France)
196.52.21.11 (LogicWeb, US / South Africa)
75.127.2.116 (Foroquimica SL / ColoCrossing, US)

Malware spam: "Message from mibser_00919013013"

I have only one sample of this rather terse email with no body text:
From:    scan@victimdomain
Reply-To:    scan@victimdomain
To:    hiett@victimdomain
Date:    30 November 2015 at 09:22
Subject:    Message from mibser_00919013013
The spam appears to originate from within the victim's own domain, but it does not. In the sample I saw, the attachment was named Smibser_00915110211090.xls, had a VirusTotal detection rate of 3/54 and contained this malicious macro [pastebin]. .

According to this Hybrid Analysis report and this Malwr report the macro downloads a malicious executable from:

velitolu.com/89u87/454sd.exe

This binary has a detection rate of 3/55. Automated report tools [1] [2] show network traffic to:

94.73.155.12 (Cizgi Telekomunikasyon Anonim Sirketi, Turkey)
42.117.2.85 (FPT Telecom Company, Russia)
89.189.174.19 (Sibirskie Seti Novokuznetsk, Russia)
5.63.88.100 (Centr, Kazakhstan)


The payload is likely to be the Dridex banking trojan:

Random "Payment" spam leads to Dridex

I have only seen one version of this spam message so far:

From:    Basia Slater [provequipmex@provequip.com.mx]
Date:    26 November 2015 at 12:00
Subject:    GVH Payment

I hope you had a good weekend.
Please check the payment confirmation attached to this email. The Transaction should appear on your bank in 2 days.

This sample had a document name of I654WWFR3C6.doc which has a VirusTotal detection rate of 6/55, containing this malicious macro [pastebin]. The Malwr report for this version indicates a download from:

harbourviewnl.ca/jo.jpg?6625

According to that Malwr report, it drops a file YSpq2bkGVIi5yaPcv6667.exe (MD5 6c14578c2b77b1917b3dee9da6efcd56) which has a detection rate of 1/53. The Hybrid Analysis report and Malwr report for that indicates malicious traffic to:

94.73.155.10 (Telekomunikasyon Anonim Sirketi, Turkey)
199.175.55.116 (VPS Cheap INC, US)


Note that 94.73.155.12 is mentioned in this other Dridex report today, both IPs form part of a small subnet of  94.73.155.8/29 suballocated to one "Geray Timur Akkurt".

My contacts (you know who you are, thank you) indicate that the emails are generated according to the following pattern:

> From: (random)
> Subject: ABC Transaction
- raw Subject: =?UTF-8?Q?ABC__Transaction?=
- matching /[A-Z]{1,3} (Invoice|Payment|Transaction|Transfer)/
> X-mailer: Thunderbird 9.23
- matching /[1-9]\.[1-9]{2}/
Attachment: "Z98Y76.doc"
- matching /[A-Z0-9]{4,14}\.doc/
They indicate an additional download location of:

gofishretail.com/jo.jpg?[4-digit-random-number]

with an additional C2 location of:
