Malware spam: no-replay@my-fax.com / "Employee Documents - Internal Use"

This fake fax spam leads to malware:

From:    Fax [no-replay@my-fax.com]
Date:    19 December 2014 at 15:37
Subject:    Employee Documents - Internal Use

DOCUMENT NOTIFICATION, Powered by NetDocuments

DOCUMENT NAME: Fax Documents

The download locations in the email vary, so far I have seen:


Clicking the link downloads a file fax8127480_924_pdf.zip which in turn contains a malicious executable fax8127480_924.exe which has a VirusTotal detection rate of 3/55. Most automated analysis tools are inconclusive [1] [2] but the VT report shows network connections to the following locations:

Malware spam: "BACS payment Ref:901109RW"

This spam comes with a malicious attachment, in a format similar to the following:

From:    Fern
Date:    19 December 2014 at 10:09
Subject:    BACS payment Ref:901109RW

Please see below our payment confirmation for funds into your account on Tuesday re invoice 901109RW

Accounts Assistant
Tel:  01874 662 346
Fax: 01874 501 248

To add credibility, the attachment has the same name as the reference in the subject and body text (in this case it is 901109RW.xls). The reference is randomly generated.

So far, I have seen three different type of attachment, all undetected by AV vendors [1] [2] [3] containing a different malicious macro each [1] [2] [3] [pastebin]. These macros then try to download an executable from the following locations:

The file is downloaded as test.exe and is then moved to %TEMP%\VMUYXWYSFXQ.exe. It has a VirusTotal detection rate of 2/54. VT also reports that it phones home to (PE "Filipets Igor Victorovych", Ukraine)

Additional analysis is pending.

A further version of this is doing the rounds with an attachment which also has zero detections at VirusTotal and a different macro [pastebin], however it downloads the same binary from as the previous example does.

Malware spam: aquaid.co.uk "Card Receipt"

[UPDATE: as of December 2015, there is a new version of the spam doing the rounds]

This spam claims to be from the legitimate firm AquAid, but it isn't. Instead it comes with a malcious attachment. The email is a forgery, AquAid are not sending the spam, nor have their systems been compromised in any way.

In the sample I have seen, the attachment is called CAR014 151239.doc which is malicious, but only has a VirusTotal detection rate of 2/54. This particular document (note that there are usually several different documents in the spam run) contains this malicious macro [pastebin]. This macro downloads a malware executable from:


..which is saved as %TEMP%\YEWZMJFAHIB.exe - this has a marginally better detection rate of 3/53.

The ThreatExpert report shows connections to the following two IPs: (1&1, US) (Strato AG, Germany)

The Malwr report shows that it drops a DLL which is very poorly detected but is probably the Dridex banking trojan.

Recommended blocklist:

FOR RESEARCHERS ONLY: a copy of the malicious DOC attachment plus dropped files can be found here. Password is "infected". Only handle these if you know what you are doing.

UPDATE 2015-01-13

This spam keeps coming back every few days or so. This time the attachment has a VirusTotal detection rate of 3/57 and the malicious macro it contains [pastebin] downloads from:


This file has a VirusTotal detection rate of 2/57. The Malwr report shows it phoning home to:

It also drops a DLL with a detection rate of 2/57.

UPDATE 2015-02-25

Another version of this spam run is in progress, with these malicious macros [1] [2] downloading from the following locations:


This malware is the same as used in this spam run.

"Blocked ACH Transfer" spam has a malicious DOC attachment

Another spam run pushing a malicious Word attachment..

Date:    17 December 2014 at 07:27
Subject:    Blocked ACH Transfer

The ACH transaction (ID: 618003565), recently sent from your online banking account, was rejected by the Electronic Payments Association.

Canceled transaction
ACH file Case ID     623742
Total Amount     2644.93 USD
Sender e-mail     info@mobilegazette.com
Reason for rejection     See attached word file
Please see the document provided below to have more details about this issue.

Attached is a file ACH transaction 3360.doc which isn't actually a Word 97-2003 document at all, but a malicious Word 2007 document that would normally have a .DOCX extension (which is basically a ZIP file). The current VirusTotal detection rate of this is just 1/55.

Inside this is a malicious macro [pastebin] which downloads a file from:


This has a VirusTotal detection rate of just 1/54. The Malwr report shows it POSTING to (Fornex Hosting, Germany) and also a query to (Atlantic.net, US). Presumably this then drops additional components onto the infected system, although I do not know what they are.

"PL REMITTANCE DETAILS ref844127RH" malware spam

This fake remittance advice comes with a malicious Excel attachment.

From:    Briana
Date:    17 December 2014 at 08:42
Subject:    PL REMITTANCE DETAILS ref844127RH

The attached remittance details the payment of £664.89 made on 16-DEC-2014 by BACSE.

This email was generated using PL Payment Remittance of Integra Finance System.

Can you please check that your supplier details are correct, if any changes are required please email back to this email address quoting your remittance reference.

The reference in the subject and the name of the Excel attachment differ from email to email, but are always consistent in the same message. There are two poorly detected malicious Excel files that I have seen [1] [2] containing two slightly different macros [1] [2] which then reach out to the following download locations:

The file from these locations is downloaded as test.exe and is then saved to %TEMP%\VMHKWKMKEUQ.exe. This has a VirusTotal detection rate of 1/55. The ThreatTrack report [pdf] shows it POSTing to the following IP: (PE "Filipets Igor Victorovych", Ukraine)

This IP has been used in several recent attacks and I strongly recommend blocking it.

The Malwr report also shows it dropping a malicious DLL identified as Dridex.

The ThreatExpert report gives some different IPs being contacted: (Denes Balazs / HostEurope, Germany) (PlusServer, Germany)

The Ukrainian IP is definitely malicious, but if you wanted to establish maximum protection then I would recommend the following blocklist:

Spam: "Localizan a los 43 estudiantes desaparecidos en Ayotzinapa"

This Spanish-language malware spam comes with a malicious attachment.

From:    El Universal

Subject:    Localizan a los 43 estudiantes desaparecidos en Ayotzinapa.

Localizan a los 43 estudiantes desaparecidos en Ayotzinapa.

Hoy 16 de diciembre del 2014 por la madrugada, agentes de la Policía Ministerial de Guerrero
han localizado con vida a los 43 estudiantes, desaparecidos el dia 26 de septiembre del 2014.

Para ver imágenes exclusivas del reencuentro de los estudiantes con sus familias, y las condiciones en que
vivieron durante su secuestro, anexamos un documento en este correo electrónico en formato Microsoft Word.

This translates roughly as:

Located at 43 students missing in Ayotzinapa.

Today December 16, 2014 at dawn, agents of the Ministerial Police Guerrero
have been located alive at 43 students, missing the day September 26, 2014.

To view exclusive footage of the reunion of students and their families, and the conditions under which
They lived during his abduction, we attach a document to this email in Microsoft Word format.

The Universal © All Rights Reserved 2014.
This email relates to the kidnapping and possible murder of 43 Mexican students which has been blamed by some on the Mexican Police.

The Word document contains a malicious macro, and detailed instructions for the victim on how to disable the inbuilt security to enable it to run.

Once this has been done, the malicious macro [pastebin] runs. This attempts to download a file from:


At the moment, this download location is coming up with a 404 error. If the download were to work, it would save the file as %TEMP%\ test00010.exe. The Word document has a moderate detection rate of 10/54.

This type of malicious spam has been around for a long time, and this particular technique seems to be exclusively in Spanish, I have never seen this attack in English or any other language.

Malware spam: UK GEOLOGY PROJECT by "Rough & Tumble" with "Moussa Minerals" [roughandtumble63@yahoo.co.uk]

This somewhat odd and terse spam comes with a malicious attachment.

From:    UK GEOLOGY PROJECT by "Rough & Tumble" with "Moussa Minerals" <roughandtumble63@yahoo.co.uk>
Date:    17 December 2014 at 07:20
Subject:    Invoice as requested
There is no body text, but there is an malicious DOC attachment named 20140918_122519.doc which come in two slightly different versions with poor detection rates [1] [2]. The macros have been subtly changed from recent spam runs [1] [2] [pastebin] and download a second stage from one of the following locations:


This malicious executable is saved as %TEMP%\ADGYMSEKRJE.exe and has a detection rate of only 2/54.

Is is common with recent similar malware attempts, it attempts to phone home to (1&1, US) as shown in the ThreatTrack report [pdf]. The Malwr report indicates a dropped file with an MD5 of ee826c184155a1fa1aea984f914e606a which is probably Dridex.

Malware spam: IFS Applications / vitacress.co.uk / DOC-file for report is ready

This fake payment advice spam is not from Vitacress but is a forgery with a malicious Word document attached.
From:    IFS Applications [Do_Not_Reply@vitacress.co.uk]
Date:    15 December 2014 at 07:49
Subject:    DOC-file for report is ready

The DOC-file for report Payment Advice is ready and is attached in this mail.
Attached is a file Payment Advice_593016.doc which is actually one of two different documents with zero detections at VirusTotal [1] [2] and contain one of two malicious macros [1] [2] [pastebin] that download a malware binary from one of the following locations:


This file is saved as %TEMP%\DYIATHUQLCW.exe  and is currently has a VirusTotal detection rate of just 1/52.

The ThreatExpert report and Malwr report shows attempted connections to the following IPs which have been used in many recent attacks and should be blocked if you can: (Ministry of Education, Thailand) (1&1, US)

The malware almost definitely drops the Dridex trojan onto the target system, but I have not been able to get a sample of this yet.

UPDATE 2014-12-16

A second wave of spam is in progress with a pair of new malicious Word documents with low detection rates [1] [2] containing new macros [1] [2] that download a malicious file from the following locations:


This file is saved as %TEMP%\TQWTGECOROR.exe and it currently has a detection rate of just 1/54. The Malwr report shows it posting to yet again, although it does not show the dropped Dridex binary that I would expect to see.

Combining some extra lookup in the Malwr report indicates that these following IPs are suspect: (Atlantic.net, US) (Fornex Hosting, Germany) (Briz, Ukraine) (OVH, France) (Ohio Public Libraries, US) (Leaseweb, Netherlands)

A malicious DLL is dropped onto the system with a VirusTotal detection rate of 2/56. The only detections are generic, but similar dropped DLLs have been the Dridex banking trojan.

Dear Customer

Please find attached your invoice for Week 49 2014.

In order to open the attached DOC file you will need
the software Microsoft Office Word.

Yours sincerely

If you are not the intended recipient, be advised that
you have received this email in error and that any use,
dissemination, forwarding, printing or copying of

This spam is not from UK Fuels Ltd or ebillinvoice.com and is a forgery. Attached is a malicious Word document which in the sample I have seen is undetected by AV vendors. This downloads a file from the following location:


This is downloaded and saved to %TEMP%\LNKCLHSARFL.exe. This binary only has a detection rate of 3/56 at VirusTotal.

The Malwr report shows that it POSTs data to (Ministry of Education, Thailand), which has been commonly used in this sort of attack (I strongly recommend that you block this IP). It also drops a DLL which is probably Dridex, which has a detection rate of only 1/55.

UPDATE 2014-12-12

Another spam run pushing this is in progress, with two different Word attachments seen so far (all called  35056_49_2014.doc. These are currently undetected by AV vendors [1] [2] and contains two slightly different macros [1] [2] [pastebin] that then attempt to download a binary from one of the following locations:


This is then saved as %TEMP%\RPDWVRNDBGX.exe. This executable is malicious but has a VirusTotal detection rate of just 2/56. The ThreatExpert report shows connections to: (Ministry of Education, Thailand) (1&1, US)

Both these IPs have been seen before and are definitely worth blocking. According to the Malwr report, this executable drops a DLL widely identified as the Dridex banking trojan.

This Tweet from @Kafeine about the Angler EK drew my attention to a small block of OVH UK addresses of which appear to be completely dedicated to distributing malware.

There are also some doubtful looking IP addresses on which may we have a malicious purpose.

The attachment is 2014-12-4_12-32-28_98348936010.doc which looks like an old-style .DOC file, but is actually a newer format .DOCX document, which is poorly detected by AV vendors. Some investigation shows that it contains a malicious macro [pastebin].

The macro downloads a file from http://hiro-wish.com/js/bin.exe which is completely undetected by any AV vendor at present. According to the internal data, this is a Windows Media Player component although the compile date is today so this seems unlikely.

"K J Watking & Co" fake Remittance Advice spam

This fake remittance advice spam has been hammering my inbox this morning. It uses randomly generated sender names but has a consistent fake company name of K J Watking & Co which is very close to a legitimate firm K J Watkin & Co who have nothing to do with this.

The Excel attachments have random names such as BAC_0577719P.xls or BAC_581969Q.xls. So far I have seen two versions of these, neither of which are detected as malicious by any vendors [1] [2].

Each spreadsheet contains a different but similar malicious macro [1] [2] [pastebin] which then download a binary from the following locations:

This file is downloaded as test.exe and is then moved to %TEMP%\EWSUVRXTBUU.exe. It has a VirusTotal detection rate of just 2/52. According to the Malwr report this then drops a DLL with another low detection rate which is identified as Dridex. The ThreatExpert report [pdf] indicates that the malware attempts to communicate with the following IPs: (PE "Filipets Igor Victorovych", Ukraine)
(PlusNet, UK)

Something evil on (KolosokIvan-net / Ivan Kolosok)

The IP address range of (KolosokIvan-net) appears to be dedicated purely to providing phone-home servers for TorrentLocker or some other similar malware.

In the past, this IP range has hosted various sites which have moved off. At the moment it seems to host just the following domains:


Active IPs are as follows:

Out of those domains, these following ones are linked with some sort of file locker malware:

casinoroyal7.ru [report]
clubstore29.ru [report]
yourwebsupport.ru [report]
chooseyourhost.ru [report]

The other domains have virtually no reference to them at all, which is somewhat suspicious.

More malware on Crissic Solutions LLC

Another bunch of IPs on Crissic Solutions LLC, leading to what appears to be the Angler EK (see this URLquery report): [VirusTotal report] [VirusTotal report] [VirusTotal report] [VirusTotal report]

The following domains are being exploited (although there will probably be more soon).


Subdomains in use start with one of qwe. or asd. or zxc. (see examples here [pastebin]).

Crissic Solutions LLC operates which does have some legitimate sites in it, but since I have previously recommended blocking and and now with multiple servers on also compromised then I suspect that temporarily blocking the entire /19 is the way to go.

Q:is sync.audtd.com a virus? A:probably not.

One of those things that makes you go "hmmm".. I kept seeing a lot of suspect looking traffic from Russian sites to sync.audtd.com, with strings like this:


audtd.com is parked on a Voxility IP of I block large swathes of Voxility IP space because it has bad reputation, but it does have some legitimate customers. The domain registration details are hidden:

Registrant City: Nobby Beach
Registrant State/Province: Queensland
Registrant Postal Code: QLD 4218
Registrant Country: AU
Registrant Phone: +45.36946676
Registrant Phone Ext:

Registrant Email: contact@privacyprotect.org

However, sync.audtd.com is hosted on three completely different IPs:

These are hosted by Hetzner in Germany. Not exactly a squeaky clean network either, but they do have a lot of legitimate customers in addition to some evil ones.

Some Googling around and poking about at the very bottom of the search results reveals a possible lead in a Russian-language privacy policy [pdf] on a domain tbighistory.com. There was an English-language version that has since been deleted which read:

Last Update: 5 September 2014

This site is called "The Big History" and it belongs to a clearly identified Russian company called Auditorius.

So, in fact Auditorius do fully spell out what they are doing in their privacy policy.. but the problem is that it isn't on the audtd.com domain itself, and rather stupidly they are using anonymous WHOIS details (plus some questionable websites). I think the lesson is that if you ARE involved in a legitimate tracking activity, then you must make sure that it is obvious and people can find out what is happening easily. If you don't people will just assume that is a virus.

Tainted network: Crissic Solutions (

Several IPs hosted on the Crissic Solutions range of (suballocated from QuadraNet) have been hosting exploit kits in the past few days, leading to Cryptolocker and other nastiness.

I analysed over 1500 sites hosted in the Crissic IP address range (report here [csv]) and many sites were already marked as being malicious by Google, and some other sites obviously follow the same naming pattern and must be considered as malicious.

Malware is hosted on the following IPs: [VT report] [VT report] [VT report] [VT report] [VT report] [VT report] [VT report] [VT report] [VT report] [VT report] [VT report]

Given the concentration of active malicious servers in and then I would recommend blocking you traffic to those ranges at least temporarily, despite there being legitimate sites in that range. You might choose to block the entire /19 of course, I will leave you to look at the evidence.

The following domains are being used to spread malware (new domains are being added all the time, blocking these may not be effective):

In this case the link in the email goes to http://illen-beauty.ru/wp-admin/3PAbHfSM5FEma from where it downloads a file 2014_11_rechnung_1_1_000309399002.zip containing a malicious executable 2014_11_rechnung_1_1_000309399002_4884_9849_00483_00222_0039459856_29392_000000002008.exe  which at the moment is quite widely detected at VirusTotal with 22/56 engines coming up positive.

The Malwr report shows that the payload is hardened against analysis, but it does show an attempted connection to (UK2.net, UK) which might be worth looking for.
