I have seen two variants of the document (VirusTotal [1] [2]). Analysis of the documents is pending, however it is likely to be the Dridex banking trojan.

UPDATE 1

There is a second variant of the spam with essentially the same (undefined) payload:

From:    Heather Ewing
Date:    18 February 2016 at 08:41
Subject:    Invoice

Dear Sir/Madam,

I trust this email finds you well,

Please see attached file regarding clients recent bill. Should you need further assistances lease feel free to email us.

Best Regards,

Heather Ewing
The Bank of New York Mellon Corporation www.bnymellon.com

In this case the attachment was named Invoice51633050.doc - automated analysis is inconclusive. An examination of the XML attachment [pastebin] indicates that it may be malformed.

UPDATE 2

A contact (thank you) analysed one of the samples and found that the document downloaded an executable from:

killerjeff.free.fr/2/2.exe

According to this Malwr report this is the Locky ransomware, and it phones home to:

95.181.171.58 (QWARTA LLC, Russia)
69.195.129.70 (Joes Data Center, US)

I suspect that the second one may be a sinkhole, but there should be no ill effects from blocking it.


UPDATE 3

A couple more samples have come to light [1] [2] one of which shows a new phone home location of:

185.14.30.97 (ITL Serverius, NL)

UPDATE 4

From user Ralf9000 at VirusTotal here are some more download locations:

onigirigohan.web.fc2.com/1/1.exe
killerjeff.free.fr/2/2.exe
uponor.otistores.com/3/3.exe
premium34.tmweb.ru/4/4.exe
bebikiask.bc00.info/5/5.exe
avp-mech.ru/7/7.exe

6.exe seems to be missing. Analysis of these is pending.

UPDATE 5

According to these Malwr reports on all the available samples [1] [2] [3] [4] [5] [6] the various versions of Locky seem to call back to:


95.181.171.58 (QWARTA LLC, Russia)
31.41.47.37 (Relink Ltd, Russia)
185.14.30.97 (ITL, Ukraine / Serverius, Netherlands)
69.195.129.70 (Joes Datacenter, US)

I have omitted what appear to be obvious sinkholes.

Recommended blocklist:
95.181.171.58
31.41.47.37
185.14.30.97
69.195.129.70

Malware spam: tracking documents / cmsharpscan@gmail.com

This fake document scan spam has a malicious attachment:

From:    cmsharpscan3589@gmail.com

Subject:    tracking documents

Attached file is scanned image in DOC format.

I have only seen a single sample of this with an attachment cmsharpscan@gmail.com_20160217_132046.docm which has a VirusTotal detection rate of 7/54. According the the Malwr analysis of the document, the payload is the Locky ransomware and is identical to the earlier attach described here.

In the sample I saw, the attachment was named 19875_Rechnung_2016-11365_20160215.docm and has a VirusTotal detection rate of 5/54.

According to this Malwr report  the binary attempts to download the Locky ransomware (seemingly a product of those behind the Dridex banking trojan). It attempts to download a binary from:

feestineendoos.nl/system/logs/7623dh3f.exe?.7055475

This dropped file has a detection rate of 3/53.  Analysis of the file is pending, but overall this has been made more complicated because the Locky installer calls out to a number of domains, many of which actually appear to have been sinkholed.

Machines infected with Locky will display a message similar to this:

Unfortunately, the only known way to recover from this is to restore files from offline backup once the infection has been removed from the PC.

UPDATE

Another version plopped into my inbox, VT 7/54  and according to this Malwr report, it downloads from:

nadeenk.sa/system/logs/7623dh3f.exe?.7055475

This variant POSTs to a server at:

46.4.239.76 (Myidealhost.com  / Hetzner, Germany)

It is likely that the C2 server (identified in the previous report) is:

85.25.149.246 (PlusServer AG, Germany)

Malware spam: Fwd:Accumsan Neque LLC Updated Invoice / Please turn on the Edit mode and Macroses!

This malware spam may come from several different companies, but I have only a single sample. It is notable for the mis-spelling of "Macros" as "Macroses" in the document.

From:    Fletcher Oliver [angel@jiahuan.com.tw]
Date:    17 February 2016 at 06:23
Subject:    Fwd:Accumsan Neque LLC Updated Invoice

Good morning

Please check the bill in attachment. In order to avoid fine  you have to pay in 12 hours.

Best regards

Fletcher Oliver
Accumsan Neque LLC

Attached is a document Q7FX9ZH.doc with the distinctive text Attention! To view this document, please turn on the Edit mode and Macroses!

Needless to say, enabling Edit mode and Macroses is a Very Bad Idea. The VirusTotal detection rate for this file is just 2/54. Hybrid Analysis [1] [2] shows that the macro first downloads from:

www.design-i-do.com/mgs.jpg?OOUxs4smZLQtUBK=54

This looks to be an unremarkable JPEG file..

(Note that I have munged the JPEG slightly to stop virus scanners triggering). As far as I can tell, the JPEG actually contains data that is decrypted by the macro (a technique called steganography). A malicious VBS is created [pastebin] and a malicious EXE file is dropped with a VirusTotal result of 7/54.

Automated analysis of the dropped binary [1] [2] shows that it phones home to:

216.59.16.25 (Immedion LLC, US / VirtuaServer Informica Ltda, Brazil)

I strongly recommend that you block traffic to that IP. Payload is uncertain, but possibly the Dridex banking trojan.

Malware spam: ATTN: Invoice J-06593788 from random companies

This fake financial spam does not come from Apache Corporation but instead is a simple forgery with a malicious attachment.

From:    June Rojas [RojasJune95@myfairpoint.net]
Date:    16 February 2016 at 09:34
Subject:    ATTN: Invoice J-06593788

Dear nhardy,

Please see the attached invoice (Microsoft Word Document) and remit payment according to the terms listed at the bottom of the invoice.

Let us know if you have any questions.

We greatly appreciate your business!

June Rojas
Apache Corporation      www.apachecorp.com

Other versions of this spam may come from other corporations. In the single sample I have seen there is an attached file invoice_J-06593788.doc which has a VirusTotal detection rate of 5/54. Analysis is pending, however this is likely to be the Dridex banking trojan.

UPDATE 1

This Dridex run exhibits a change in behaviour from previous ones. I acquired three samples of the spam run and ran the Hybrid Analysis report on them [1] [2] [3] and it shows that the macro dowloads from one of the following locations:

www.southlife.church/34gf5y/r34f3345g.exe
www.iglobali.com/34gf5y/r34f3345g.exe
www.jesusdenazaret.com.ve/34gf5y/r34f3345g.exe

Curiously, the binary downloaded from each location is different, with the following MD5s:

CBE75061EB46ADABC434EAD22F85B36E
B06D9DD17C69ED2AE75D9E40B2631B42
FB6CA1CD232151D667F6CD2484FEE8C8

Each one phones home to a different location, the ones I have identified are:

109.234.38.35 (McHost.ru, Russia)
86.104.134.144 (One Telecom SRL, Moldova)
195.64.154.14 (Ukrainian Internet Names Center, Ukraine)

There may be other samples with other behaviour.

UPDATE 2

It is possible that this is dropping ransomware, not Dridex. One other download location identified here:

www.villaggio.airwave.at/34gf5y/r34f3345g.exe

This one has an MD5 of:

1FD40A253BAB50AED41C285E982FCA9C

Detection rate is 5/53 but I do not yet know where this phones home to.

UPDATE 3

That last sample phones home to:

91.195.12.185 (PE Astakhov Pavel Viktorovich, Ukraine)

according to this Hybrid Analysis.

Recommended blocklist:
109.234.38.0/24
86.104.134.128/25
195.64.154.14
91.195.12.185 

UPDATE 4

It appears that this is dropping some ransomware called "Locky" apparently by the makers of Dridex, according to this.

Attached is a file SKM_C3350160212101601.docm which comes in several different variants. The macro in the document attempts to download a malicious executable from:

I have only seen a single sample of this with an attachment OutstandingStatement201602111650.js which has a VirusTotal detection rate of 0/53. The Malwr analysis shows that this script downloads an executable from:

gp-training.net/09u8h76f/65fg67n

There are probably a few other download locations. This binary has a detection rate of 2/54.  The Malwr report also indicates that it phones home to:

87.229.86.20 (ZNET Telekom Zrt, Hungary)

I strongly recommend that you block traffic to that IP. The payload is the Dridex banking trojan.

Malware spam: "New Doc 115" / "Sent from Yahoo Mail on Android"

This rather terse spam has a malicious attachment:

From:    admin [ali73_2008949@yahoo.co.uk]
Date:    10 February 2016 at 10:16
Subject:    New Doc 115

Sent from Yahoo Mail on Android

The sender's email address varies from message to message. Attached is a file New Doc 115.doc which is reportedly identical to the one found in this spam campaign.

Malware spam: Emailing: MX62EDO 10.02.2016 / documents@dmb-ltd.co.uk

This spam has a malicious attachment:

From     documents@dmb-ltd.co.uk
Date     Wed, 10 Feb 2016 11:12:41 +0200
Subject     Emailing: MX62EDO 10.02.2016

Your message is ready to be sent with the following file or link
attachments:

MX62EDO  10.02.2016 SERVICE SHEET


Note: To protect against computer viruses, e-mail programs may prevent
sending or receiving certain types of file attachments.  Check your e-mail
security settings to determine how attachments are handled.

Attached is a malicious document named MX62EDO 10.02.2016.doc. I haven't had time to analyse these myself, but a trusted source (thank you) says that there are three different variants of documents, downloading a malicious executable from the following locations:

calflytech.com/09u8h76f/65fg67n
g-t-c.co.uk/09u8h76f/65fg67n
opoai.com/09u8h76f/65fg67n

This drops an executable with a VirusTotal detection rate of 6/55.  This malware calls back to the following IPs:

87.229.86.20 (ZNET Telekom Zrt, Hungary)
50.56.184.194 (Rackspace, US)
144.76.73.3 (Hetzner, Germany)

The payload is the Dridex banking trojan. Some chatter I have seen indicates that this has been hardened against analysis.

Recommended blocklist:
87.229.86.20
50.56.184.194
144.76.73.3
 

Malware spam: "Accounts" / [accounts_do_not_reply@aldridgesecurity.co.uk]

This rather terse spam does not come from Aldridge Security but it is instead a simple forgery with a malicious attachment. There is no subject.

I have only seen a single sample with an attachment document2016-02-09-103153.doc which has a VirusTotal detection rate of 5/54. Automated analysis [1] [2] shows that it downloads a malicious executable from:

promo.clickencer.com/4wde34f/4gevfdg

This has a detection rate of 5/54. Those analyses indicates that the malware phones home to:

50.56.184.194 (Rackspace, US)

I strongly recommend that you block traffic to that IP. The payload is the Dridex banking trojan.

Malware spam: "Accounts Documentation - Invoices" / CreditControl@crosswater.co.uk

This fake financial spam does not come from Crosswater Holdings, but it is instead a simple forgery with a malicious attachment:

From:    CreditControl@crosswater.co.uk
Date:    8 February 2016 at 10:34
Subject:    Accounts Documentation - Invoices

Please find attached the invoice(s) raised on your account today. If you have more than one invoice they will all be in the single attachment above.

If you have any queries please do not hesitate to contact the Credit Controller who deals with your account.
Alternatively if you do not know the name of the Credit Controller you can contact us at:

Accounts@crosswater-holdings.co.uk

or call us on 0845 873 8840

Please do not reply to this E-mail as this is a forwarding address only.

Attached is a malicious script ~13190.js which comes in at least two different variants (VirusTotal [1] [2]). According to automated analysis [3] [4] [5] [6] these scripts download from:

hydroxylapatites7.meximas.com/98876hg5/45gt454h
80.109.240.71/~l.pennings/98876hg5/45gt454h

This drops an executable with a detection rate of 3/53 which appears to phone home to:

188.40.224.73 (NoTag, Germany)

I strongly recommend that you block traffic to that IP address. The payload is likely to be the Dridex banking trojan.

I have only seen one sample with an attachment named ebill0200442.xls which contains this malicious macro [pastebin] which is different to recent Dridex macros, and is similar to one first seen yesterday. According to this Malwr report it downloads an executable from:

www.trulygreen.net/43543r34r/843tf.exe

also reported is as a download location is:

www.mraguas.com/43543r34r/843tf.exe

If you look at the details of the Malwr report, it seems that the the script does creates a LOT of files all over the place. The dropped executable has a detection rate of 4/52 and according to this Hybrid Analysis shows that it phones home to:

62.76.191.108 (Clodo-Cloud / IT-House, Russia)

This is the same IP address as seen earlier, put the payload has now changed. Blocking that IP would be wise, and I would suggest that blocking 62.76.184.0/21 is probably worth considering too.

Malware spam: "More scans" / admin@victimdomain.tld / DOC201114-201114-001.js

This terse spam appears to originate from within the victim's own organisation, but it does not. Instead it is a simple forgery with a malicious attachment:

From:    admin [admin@victimdomain.tld]
Date:    4 February 2016 at 08:17
Subject:    More scans

Attached is a file DOC201114-201114-001.js which comes in a variety of different variants. The payload appears to be the Dridex banking trojan, as seen in this earlier spam run.

Malware spam: "January balance £785" / Alison Smith [ASmith056@jtcp.co.uk]

This fake financial spam does not come from J. Thomson Colour Printers, but is instead a simple forgery with a malicious attachment:

From     Alison Smith [ASmith056@jtcp.co.uk]
Date     Thu, 04 Feb 2016 10:52:21 +0300
Subject "January balance £785"

Hi,

Thank you for your recent payment of £672.

It appears the attached January invoice has been missed off of your payment. Could
you please advise when this will be paid or if there is a query with the invoice?

 P Save Paper - Do you really need to print this e-mail?

The poor company being spoofed has already been hit by this attack recently [1] [2]. The email address of the sender varies from message to message.

Attached is a file IN161561-201601.js which comes in at least five different versions (VirusTotal [1] [2] [3] [4] [5]). This is a highly obfuscated script that looks like this [pastebin] and automated analysis of the various scripts [6] [7] [8] [9] [10] [11] [12] [13] shows that the macro downloads from the following locations (there may be more):

ejanla.co/43543r34r/843tf.exe
cafecl.1pworks.com/43543r34r/843tf.exe

This binary has a detection rate of 2/52 and phones home to:

62.76.191.108 (Clodo-Cloud / IT-House, Russia)

Note that the whole 62.76.184.0/21 block is a haven for malware, but it does also have some legitimate Russian customers. You might want to consider blocking the entire range if your users don't need to visit Russian websites. The payload is the Dridex banking trojan, and although it is unusual to see a plain .js file spammed out like this, it is consistent with botnet 220.

Malware spam: "Attached Image" from canon@ the recipient's own domain

This spam pretends to come from the victim's own domain, but it doesn't. Instead it is a simple forgery with a malicious attachment.

From:    canon@victimdomain.tld
Date:    3 February 2016 at 12:09
Subject:    Attached Image

There is no body text. Attached is a file 1690_001.xls of which I have seen a single variant with a detection rate of 9/54. The Hybrid Analysis shows it downloading an executable from:


best-drum-set.com/43rf3dw/34frgegrg.exe

This has a detection rate of 6/51 and is the same binary as used in this other spam attack today.

Malware spam: "Invoice MOJU-0939" / Accounts [message-service@post.xero.com]

This fake financial spam comes with a malicious attachment. It does not come from Moju Ltd but is instead a simple forgery with a malicious attachment:

From:    Accounts [message-service@post.xero.com]
Date:    3 February 2016 at 09:04
Subject:    Invoice MOJU-0939

Hi,

Here's invoice MOJU-0939 for 47.52 GBP. For last weeks delivery.

The amount outstanding of 47.52 GBP is due on 25 Feb 2016.

If you have any questions, please let us know.

Thanks,
Moju Ltd

I have only seen one sample of this, with an attachment named Invoice MOJU-0939.zip containing a malicious script invoice_id4050638124.js that has detection rate of 2/53 and which according to this Malwr report downloads a binary from:

www.ni-na27.wc.shopserve.jp/43rf3dw/34frgegrg.exe

This payload is the same as seen in this concurrent spam run.

Malware spam: "GS Toilet Hire - Invoice (SI-523) for £60.00, due on 28/02/2016"

This fake financial spam does not come from GS Toilet Hire but is instead a simple forgery with a malicious attachment. In other words, if you open it.. you will be in the sh*t.

From:    GS Toilet Hire [donotreply@sageone.com]
Date:    3 February 2016 at 09:12
Subject:    GS Toilet Hire - Invoice (SI-523) for £60.00, due on 28/02/2016

Good morning

I have seen two samples of this, both with an attachment named Sales_Invoice_SI-523_GS Toilet Hire.pdf.zip which contains a malicious Javascript file with a name like invoice_id6395788111.js. The two samples that I have seen have low detection rates [1] [2] containing some highly obfuscated scripts [3] [4] which according to these analyses [5] [6] [7] downloads a binary from one of the following locations:

obstipatie.nu/43rf3dw/34frgegrg.exe
bjhaggerty.com/43rf3dw/34frgegrg.exe
(also www.ni-na27.wc.shopserve.jp/43rf3dw/34frgegrg.exe from this related spam run)

This type of download indicates that this is Dridex 220, it is unusual for it to be spammed out with a Javascript-in-ZIP format rather than a malicious Office macro. The binary has a detection rate of 5/49 and this Hybrid Analysis shows the malware phoning home to:

91.239.232.145 (Hostpro Ltd, Ukraine)

I strongly recommend that you block all traffic to that IP, and possibly the 91.239.232.0/22 block in which it resides.

UPDATE

The same spam is being sent out with a more traditional DOC attachment, Sales_Invoice_SI-523_GS Toilet Hire.doc which comes in at least two different variants (VirusTotal [1] [2]) which according to these Malwr reports [3] [4] downloads a binary from the following locations:

xinchunge.com/xinchunge.com/43rf3dw/34frgegrg.exe
taukband.com/43rf3dw/34frgegrg.exe
(also best-drum-set.com/43rf3dw/34frgegrg.exe from this later spam run)

This is a different binary from before, with a detection rate of 4/53. It still phones home to the same location.

Attached is a malicious document Leathams Ltd_INV2372039.doc which comes in at least two different versions (VirusTotal [1] [2]). The Malwr analysis for one of those samples shows a download from:

fillingsystem.com/5h4g/0oi545gfgf.exe

This is similar to a spam run earlier, but now the payload has changed to one with a detection rate of precisely zero (MD5 0d37099eaff9c507c782fd81c715255b). Analysis of this is pending. The payload is the Dridex banking trojan.

UPDATE 

Automated analysis [1] [2] shows the executable phoning home to:

91.239.232.145 (Hostpro Ltd, Ukraine)

I strongly recommend blocking traffic to that IP, or the whole /22 in which it resides.
