I captured two samples with detection rate of about 3/54 [1] [2] and the Malwr reports for those [3] [4] indicate the macro in the document downloads a malicious executable from:

steinleitner-online.net/09u8h76f/65fg67n [reported here]

This dropped file has a detection rate of 5/54 (MD5 7bf7df5e630242182fa95adff4963921). This Hybrid Analysis report indicates subsequent traffic to: (Universidad Tecnologica de la Mixteca, Mexico) (ZNET Telekom Zrt, Hungary) (ispOne business GmbH, Germany)

The payload is the Dridex banking trojan.

Attached is a Word document [VT 6/55]with various filenames:


All the samples I have seen have an identical document with different names, containing this malicious macro which then goes off and downloads various other components according to the Hybrid Analysis report, using the following URLs:


These appear to download as a set of malicious scripts [1] [2] [3] which then download a further component from:


This binary has a detection rate of 3/55. The Malwr report shows that it drops two other files, named as Zlatowef.exe [VT 3/55] and redtytme4.exe [VT 9/55] and it also downloads components from:

That IP is allocated to Cogent Communications in Mexico. The download is Upatre which means that the payload is almost definitely the Dyre banking trojan, even though the delivery mechanism of a Word document is unusual for Dyre.

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

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

From:    El Universal
Date:    16 December 2014 at 09:06
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.

El Universal © todos los Derechos Reservados  2014.
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.

"Notificación de transferencia de fondos a su favor" spam

This Spanish-language spam has a malicious Word document as an attachment.

Con gusto le atenderemos

The attachment is essentially the same as the one mentioned here which tries to lure the victim into removing their Word security settings so that a malicious macro can run.

The VirusTotal detection rate is a pretty poor 4/54. You can see some of the text strings in the Malwr report which feature a reverse URL of exe.ss/pw/arc/lc.paip//:ptth which is reverse to try to download a file from http://piap.cl/cra/wp/ss.exe (currently 404ing). The VBA in the document can be found here [pastebin].

As mentioned before, this is a long-running campaign apparently targeting users in Mexico, and as yet I have not seen this in any language except Spanish.

I hereby send you the status of your account on 08/Jul/2014.
We recommend you download and keep track of your assets.

The statement is attached to this email in Microsoft Word format.

For any question you can contact Super Business Line.

Best regards,
Attached is a file ESTADOCUENTA_2457.doc which contains a Word Macro virus. However, because most people's settings would stop a Macro virus running then it actually contains detailed instructions on how to remove your security settings.

The first page reads:
El contenido no puede ser mostrado.
Para poder ver el contenido de este documento debe habilitar los Macros de Microsoft Word, luego cerrar y abrir el documento.

Pruebe lo siguiente:
Habilite los Macros y luego vuelva a abrir el documento.
En este documento podrá encontrar una guía proporcionada por www.santander.com para poder habilitar los macros en su Microsoft Word.

Grupo Financiero Santander México - 2014
which roughly translates to:
The content can not be shown.
To view the content of this document should enable macros Microsoft Word, then close and reopen the document.

Try the following:
Enable Macros and then reopen the document.
In this document you will find a guide provided by www.santander.com to enable macros in your Microsoft Word.

Grupo Financiero Santander Mexico - 2014

There then follows several pages with screenshots on how to disable the security in Word and Excel.. doing which of course is a bad idea. Reloading the document will then execute the Macro virus. I have defanged the document and converted it to a PDF file here. A copy of the VBA code is here (thanks to @Techhelplistcom).

The VirusTotal analysis shows just 1/54 virus scanners detect it. The Malwr analysis gives some clues as to what is going on in the string dump, especially the reference to baulretro.cl/tienda/cache/wp/ss.exe ( / Zam Ltda, Chile) which appears to be a malicious binary (at the moment the file is 404ing, but it was working recently).

The properties of the Word document don't give much of a clue:

Authors are "OFEyDV", last saved by "clein" which matches to a few other recent malicious Spanish-language documents [1] [2] [3] [4]. The creation date indicates that perhaps this started off life as a genuine document and has been adapted for evil purposes.

Originating IP for the spam is (Langfang University, China) via (web17.gohost.com).

It's a lot of hard work to get your computer infected, but it does also look quite convincing. Word Macros are very rarely used by anything and you should definitely not fiddle with them if you don't need to.
