Malware spam: "E-bill : 6200228913 - 31.07.2015 - 0018" / "noreply.UK.ebiller@lyrecobusinessmail.com"

This fake financial spam does not come from Lyreco but is instead a simple forgery with a malicious attachment:

From:    noreply.UK.ebiller@lyrecobusinessmail.com

Subject:    E-bill : 6200228913 - 31.07.2015 - 0018

The attachment is named 0018_6200228913.docm which contains a malicious macro like this one [pastebin]. So far I have seen three different variants (Hybrid Analysis reports [1] [2] [3]) which then go and download a malicious binary from one of the following locations:

orpigagny.com/w45r3/8l6mk.exe
audiobienentendre.fr/w45r3/8l6mk.exe
immobilier-roissyenbrie.com/w45r3/8l6mk.exe


All of these sites are hosted on 94.23.55.169 (OVH, France). The binary has a detection rate of 4/55. This Malwr report shows it phoning home to 46.36.219.141 (FastVPS, Estonia). The payload is probably the Dridex banking trojan.

Spam: Countrywide Money Ltd (countrywidemoney.co.uk)

You know things must be desperate when a business turns to spam. Here's a dubious-looking spam that seems to be presenting itself in a way that looks like a get-rich-quick scheme.




From:    Countrywide Money [info@countrywidemoney.co.uk]
Reply-To:    Info@countrywidemoney.co.uk
Date:    1 August 2015 at 05:11
Subject:    Extra Income FOR YOU!

Incidentally, the Unsubscibe link doesn't work. Tsk tsk.

Now, I'm sure this is a legitimate business offer and not some sort of scam. But all those banknotes and the general pitch seems to suit an operation in Lagos rather than one in the UK. So, what can we find out about this Countrywide Money Ltd?

Let's start with the WHOIS details for the domain countrywidemoney.co.uk:

Domain name:
countrywidemoney.co.uk

Registrant:
Countrywide Money

Registrant type:
UK Individual

Registrant's address:
The registrant is a non-trading individual who has opted to have their address omitted from the WHOIS service.


A non-trading individual? Let's look at that web site for a moment..


Well, it doesn't look like a personal homepage to me. But we can look up the details of Countrywide Money Ltd at Companies House to see what we can find. It turns out that the sole director is one "Tony Edwards" who should presumably be listed on the domain WHOIS:

DIRECTOR: EDWARDS, TONY MR
Appointed: 07/06/2012
Date of Birth: 24/10/1972
Nationality: BRITISH
No. of Appointments: 3
Address:
53 FEATHER DELL
HATFIELD
UNITED KINGDOM
AL10 8DE
Country/State of Residence: UNITED KINGDOM

Let's have a look at the flashy offices in Hatfield, eh? Oh.. it looks like a residential address.


A bit of a disappointment really as the web site and brochure look so promising. A little bit more digging at DueDil shows some equally disappointing looking financials.



Hmmm.

One other odd thing, the "About Us" page says that they were founded in 2002..

But Companies House says they were only incorporated in 2012:


That's kind of.. odd. There must be some rational explanation for the discrepancy.

Anyway, I'm not sure why this person feels that promoting their business through spam is appropriate. I certainly won't be signing up to this scheme.

UPDATE 6/2/16

Somebody claiming to be Tony Edwards has made several angry comments on the end of this post, but has not addressed the simple query of where they got their mailing list from. This somewhat incoherent, ill-informed and badly spelled comments cumulated in something that could easily be misinterpreted as a threat of blackmail and even violence.


These comments are connected to a Google+ profile that looks to be genuine, but it is possible I suppose that they are coming from an imposter. My personal opinion is that if they are genuine then they simply show how unprofessional Mr Edwards is.

An explanation as to how the spam email ended up with a non opt-in address would be good. An apology for spamming would be perfectly acceptable. Threats are not.

Evil network: Malicious RATs (including milano.exe) on 185.19.85.128/26 (Datawire AG)

There's more to this spam than meets the eye:

From:    wholesale.uganda@anisuma.com
To:    "tariq@paramountdistributors.com" [wholesale.uganda@anisuma.com]
Date:    24 July 2015 at 13:31
Subject:    re:invoice

Attention
Please confirm your consignee name and address on the BL
http://a.pomf.se/cvpkgu.rar
please let update me
thanks 
"Anisuma Traders" is the name of a legitimate trading corporation with operations in several African countries, although they are not sending the spam. It looks like a phish, right? Wrong..

The apparent link to a .rar file caught my eye. In fact, the download location is not pomf.se (a defunct Swedish site) but the click chain goes like this:

http://ge.tt/api/1/files/1XjW10L2/0/blob?download
http://api.ge.tt/1/files/1XjW10L2/0/blob?download
http://ec2-54-155-123-115.eu-west-1.compute.amazonaws.com:9009/streams/1XjW10L2/stu.rar?sig=-U7AIHwQKNyk4BP6A2uOe9UYEFBYCm3SADo&type=download

The file downloaded is stu.rar which in turn contains an executable milano.exe. I'm going to take a guess and suggest that this is a Very Bad File, although the VirusTotal report give a detection rate of just 1/55 with McAfee flagging it as "BehavesLike.Win32.BackdoorNJRat.gc"

Both the Malwr and Hybrid Analysis reports show that it hooks into the OS and attempts to avoid detection. Crucially, they both show network traffic to gee.duia.eu on 185.19.85.138 (Datawire, Switzerland).

So, McAfee thinks this is a RAT and there's suspect network traffic, but what do the email headers tell us?

The "X-MDRemoteIP" header shows that the email originates from the same server it is phoning home to. This is unusual because most spam these days come from botnets, and if the originating server gets shut down for spam then the infected clients won't be able to phone home. The email routes through servers belong to jackys.com in the UAE, perhaps indicating that someone has altered their systems to allow the malicious traffic to route through.

185.19.85.138 is therefore a server of interest, but a quick look at the IP and the neighbourhood indicate that this isn't just a single popped server.. there are 58 IPs hosting what appears to be malicious data (listed at the end) taking up the entire 185.19.85.128/26 range.

I'm betting that renting a /26 slice of Swiss servers isn't cheap.

Out of all the malicious domains (listed at the end of the post), one stands out boss.milano22.com (because the binary is named milano.exe). That is related to this malware, but the WHOIS details reveal no clues.

Another one that also caught my eye because it is multihomed on so many IPs is zexio.no-ip.biz which is related to this malware from 2012 which is variously identified as Shakblades and/or Blackshades, both illicit RAT tools.

Looking at various other domains shows that they are connected with other malicious activity over the past two years or so. What that means is that this operation is not only big, but has been going on for some time.

For research purposes, a copy of the malware is here (Zip file, password=infected)

Personally, I would recommend that you block all dynamic DNS domains on a corporate network, and combined with the other potentially malicious domains gives the following recommended blocklist:

Malware spam: "Order Form for Job Number 2968347" / "steve.champion@printing.com"

This fake financial spam does not comes from printing.com but is instead a simple forgery with a malicious attachment.

Attached is a file OrderForm2968347.docm which I have seen in three different versions (there are maybe more) with various detection rates [1] [2] [3]. They contain a malicious macro like this one [pastebin].

The macro downloads a malicious binary from one of the following locations:

solution-acouphene.fr/mini/mppy.exe
surflinkmobile.fr/mini/mppy.exe
verger-etoile.fr/mini/mppy.exe


All of these are on the same compromised OVH France server of 94.23.1.145. The binary has a detection rate of just 2/54 and it is saved as %TEMP%\ihhadnic.exe. Automated analysis [1] [2] [3] shows attempted network traffic to:

85.25.199.246 (PlusServer AG, Germany)
194.58.96.45 (Reg.Ru, Russia)
31.131.251.33 (Selectel, Russia)


The payload appears to be the Dridex banking trojan.

Malware spam: "Payment Receipt" / "donotreply@dart-charge.co.uk"

This fake financial email is a simple forgery with a malicious attachment.

From     [donotreply@dart-charge.co.uk]
Date     Wed, 22 Jul 2015 19:26:51 +0700
Subject     Payment Receipt
The samples I saw had no body text and an attachment PaymentReceipt.xml [VT 5/55] which is an XML file [pastebin] with a Base64 encoded section which magically transforms into a malicious Word macro.

This macro downloads a malicious binary from:

http://puerta.fr/sandra/write.exe

Other versions of the attachment may download the same binary from different locations. This is saved as %TEMP%\mikapolne.exe and has a VirusTotal detection rate of 26/55. Automated analysis [1] [2] [3] shows it communicating with:

194.58.96.45 (Reg.Ru, Russia)

This IP has been in use in this other campaign today and is well worth blocking.

Malware spam: HMRC application with reference XXXX XXXX XXXX XXXX received / noreply@hmrc.gov.uk

These spam emails do not come from HMRC (the UK tax office) but are instead a simple forgery with a malicious attachment.
From:    noreply@hmrc.gov.uk [noreply@hmrc.gov.uk]
Date:    22 July 2015 at 13:19
Subject:    HMRC application with reference 5CSS 1QDX 27KH LRFM received

The application with reference number 5CSS 1QDX 27KH LRFM submitted by you or your agent to register for HM Revenue & Customs (HMRC)  has been received and will now be verified. HMRC will contact you if further information is needed.

The original of this email was scanned for viruses by the Government Secure Intranet virus scanning service supplied by Vodafone in partnership with Symantec. (CCTM Certificate Number 2009/09/0052.) On leaving the GSi this email was certified virus free.

Communications via the GSi may be automatically logged, monitored and/or recorded for legal purposes.

Attached is a file 2015_MURI_FOA_ONR_FOA_14-012_FINAL_EGS.doc with a VirusTotal detection rate of 7/55 which if opened (not advised) pretends to be an encrypted document that requires Active Content to be enabled.

According to this Hybrid Analysis report the embedded macro contacts the following hosts to download components:

vinestreetfilms.com/wp-content/plugins/jetpack/_inc/genericons/genericons/rtl/78672738612836.txt
midlandspestcontrol.net/wp-includes/js/tinymce/themes/advanced/skins/o2k7/78672738612836.txt
midlandspestcontrol.net//wp-includes/js/tinymce/themes/advanced/skins/o2k7/fafa.txt

This includes another malicious script. This then leads to the download of a malicious binary from:

anacornel.com/images/desene/united.exe

This has a VirusTotal detection rate of just 2/55. Automated analysis is pending.

So far I have only seen one sample with an attachment Excel Manufacturing Ltd Invoice UCB01.docm which has a VirusTotal detection rate of 8/56. The document contains this malicious macro [pastebin] which downloads a binary from:

http://amsaqwankido.com/max/bbw.exe

which is saved as %TEMP%\mikapolne.exe . This has a detection rate of 3/55 and this Malwr report shows suspect traffic to the following IP:

Automated analysis didn't work on this and frankly instead of reinventing the wheel I refer you to this note from @Techhelplistcom which reveals an executable being downloaded from:

umontreal-ca.com/ualberta/philips.exe

This domain was registered just yesterday to an anonymous person and is hosted on 89.144.10.200  (ISP4P, Germany) so we can assume that it is malicious. But here's an interesting detail.. if you look at the Word document itself it does actually claim to be from the University of Montreal (click to enlarge).



That seems like a lot of effort to go to, more than is usual for this type of drive-by attack.The malicious executable philips.exe has a detection rate of 13/55 and again, the Comments field has a useful list of IP address to block thanks to @Techhelplistcom.

This whole thing is Upatre dropping the Dyre banking trojan, and it's quite clever stuff. Perhaps your best defence is a user education programme about not enabling active content on suspect emails..

In the samples I have seen, the attachment is called bounty.doc, Giftinfo.doc, bonus.doc,
or bonusinfo.doc [VT detection rate 6/55], but the content is the same. If a potential victim opens it, the document looks like this:


If the user follows these steps, this malicious macro [pastebin] will run, infecting their machine. The Hybrid Analysis report shows the macro downloading various components from:

www.buck.tv/cms/wp-content/uploads/78672738612836.txt
www.bereciartua.com/wp-content/themes/bereciartua/78672738612836.txt
www.bereciartua.com/wp-content/themes/bereciartua/papa.txt


All of these files are actually scripts, and they appear to download a malicious executable from:

195.154.93.8/123a.exe

This has a VirusTotal detection rate of 4/55, and that same VirusTotal report shows it phoning home to:

93.185.4.90:12328/ETU2/<MACHINE_NAME>/0/51-SP3/0/MEBEFEBLGBEID
93.185.4.90:12328/ETU2/<MACHINE_NAME>/41/5/4/MEBEFEBLGBEID


We've seen the 93.185.4.90 a few times recently, and it is absolutely worth blocking and/or monitoring traffic to this IP.

The ZIP file has a detection rate of 6/55 and it contains a malicious exeuctable named FAX-1400166434-707348006719-154.scr which has a detection rate of 4/55. Automated analysis [1] [2] [3] shows a characterstic callback pattern that indicates Upatre (which always leads to the Dyre banking trojan):

This IP is allocated to C2NET in the Czech Republic. The malware also attempts to enumerate the IP address of the target by accessing checkip.dyndns.org which is a legitimate service. It is worth looking for traffic to that domain because it is a good indicator of compromise.

Malware spam: "Excelent job !" / "Good achievement !"

These spam emails appear to have randomly-generated text, which would account for the strange language.. and they come with a malicious attachment:

Date:    16 July 2015 at 12:53
Subject:    Excelent job !

Congratulations ! You will obtain a 25% commission for the latest sale. Please overlook the next papers to know the whole sum you've gained.
Daily you prove that you are the main force of our branch in the sales. I am elate and beholden to have such a gifted and able employee. Proceed the good achievements.
All the best.
Michelle Curtis Company management

---------------------

Date:    16 July 2015 at 11:53
Subject:    Good achievement !

Congratulations ! You will win a 40% rake-off for the latest sale. Please see the these documents to find out the entire sum you've won.
Everyday you assure that you are the head power of our group in the sales. I am sublime and beholden to get such a talented and skillful workman. Continue the good achievements.
With the best regards.
Sharon Silva Company management 
Attached is a malicious Word document which in the two samples I saw was called
total_sum_from_last_sale.doc
total_sum_from_latest_disposition.doc


Both these documents were identical apart from the filename, and have a VirusTotal detection rate of 4/55. Inside the document is this malicious macro [pastebin], which (according to Hybrid Analysis) downloads several components (scripts and batch files) from:

thereis.staging.nodeproduction.com/wp-content/uploads/78672738612836.txt
www.buildingwalls.co.za/wp-content/themes/corporate-10/78672738612836.txt
www.buildingwalls.co.za/wp-content/themes/corporate-10/papa.txt


These are executed, then a malicious executable is downloaded from:

midwestlabradoodles.com/wp-content/themes/twentyeleven/qwop.exe

This has a VirusTotal detection rate of 8/55 and that report plus other automated analysis tools [1] [2]  phones home to the following malicious URLs:

93.185.4.90:12317/LE2/<MACHINE_NAME>/0/51-SP3/0/MEBEFEBFEBEFJ
93.185.4.90:12319/LE2/<MACHINE_NAME>/41/7/4/


That IP belongs to C2NET in the Czech Republic. It also send non-malicious traffic to icanhazip.com (a legitimate site that returns the IP address) which is a good indicator of compromise.

This malware drops the Dyre banking trojan.

Malware spam: "Invoice reminder" / "morgan-motor.co.uk"

Nope, you haven't ordered an esoteric British sports car. This malware spam is not from the Morgan Motor Company, but is instead a simple forgery with a malicious attachment.

From     "Marie Atkins" [Marie.Atkins@morgan-motor.co.uk]
Date     Fri, 10 Jul 2015 12:50:54 +0200
Subject     Invoice reminder

Please note that so far we had not received the outstanding amounts in accordance
with the invoice enclosed below.
Unfortunately, we cannot wait another week for amounts to be settled. Kindly ask
You to arrange the payment in the nearest future (2 days).
In case the funds are not received in two days we reserve the right to use legal
approaches in order to resolve this issue.
We hope You will duly react to this notification and save good business relationships
with us.
Other senders spotted are Effie.Henry@morgan-motor.co.uk and Carmine.Randolph@morgan-motor.co.uk although there are probably others. Attached is a ZIP file named invoice-ITK709415.zip [VT 13/54] which contains a malicious executable invoice-ITK709415.scr, this has a VirusTotal detection rate of 3/55.

The Malwr report shows that this is the Upatre downloader, which always leads to the Dyre banking trojan. The characteristic callback pattern can be seen in the network traffic:

http://38.65.142.12:12569/RT77/HOME/0/51-SP3/0/ELHBEDIBEHGBEHK
http://38.65.142.12:12569/RT77/HOME/41/5/1/ELHBEDIBEHGBEHK

We've seen that IP before. Another characteristic bit of traffic (but not malicious) is a HTTP request to icanhazip.com. Although this is a legitimate service to determine the IP address of the client, it is also a pretty good indicate of Upatre/Dyre infection and is worth looking out for on your network.

The downloader seems to drop a modified version of itself, in this case called aloyzan.exe and also having a 3/55 detection rate. In additional, a file named whicalous.exe [VT 1/55] is dropped.

Dear customer

Your order 3269637 has been despatched.

Please see attachment for details.
Attached is a file 4077774.doc for which I have seen three variants [1] [2] [3] [Hybrid Analysis] which downloads a malicious executable from one of the following locations:

robindesdroits.com/43/82.exe
illustramusic.com/43/82.exe
prodasynth.com/43/82.exe

Those sites are hosted on 213.186.33.19 and 213.186.33.87 which are OVH parking IPs.

That executable has a detection rate of 8/54 and automated analysis tools [1] [2] [3] show traffic to 62.210.214.106 (OVH, France). The payload is the Dridex banking trojan.

Malware spam: "Strange bank account operation" / "Unauthorised bank account activity" / "Illegal bank account transfer" etc

Date:    8 July 2015 at 17:51
Subject:    Unauthorised bank account activity

Kindly be acknowledged that bank security department had detected suspect attempt of money withdrawal related to Your debit card.
Please check the enclosed bank statement forwarded by banking department today.
In addition attached are security details for Your control.
Robin Willis
Senior Manager

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

extract_of_bank_document.doc
fragment_of_bank_fax.doc
original_of_bank_report.doc
scan-copy_of_bank_document.doc
transcript_of_bank_statement.doc


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:

midwestlabradoodle.com/wp-content/plugins/really-simple-captcha/6727156315273.txt
artyouneed.com/wp-includes/theme-compat/6727156315273.txt
artyouneed.com/wp-includes/theme-compat/kaka.txt

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

bluemagicwarranty.com/wp-includes/theme-compat/getrichtoday.exe

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:

38.65.142.12:12551/ON12/HOME/0/51-SP3/0/ELHBEDIBEHGBEHK
38.65.142.12:12551/ON12/HOME/41/5/4/ELHBEDIBEHGBEHK


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.

Malware spam: "Statement as at 30/06/2015" / "Manchester Accounts [manchester.accounts@hobsrepro.com]" / "blogdynamoocom.exe"

This fake financial spam does not come from Hobs Reprographics plc but instead is a simple forgery with a malicious attachment. The malware also rather cheekily includes a reference to this blog. Привет, ребята!

From:    Manchester Accounts [manchester.accounts@hobsrepro.com]
Date:    6 July 2015 at 07:10
Subject:    Statement as at 30/06/2015

Please find attached statement from HOBS REPROGRAPHICS PLC as at
30/06/2015.

Please note that our payment terms are 30 days.

So far I have only seen one sample, with an attachment named ELLE013006.doc [VT 4/54] which contains this malicious macro [pastebin] which downloads a malicious executable from:

ozelduzensurucukursu.com/253/632.exe

Well, it would do, but in the sample I have there's a syntax error in the URL..

There are usually several versions of the document, probably some of the others work OK. The executable is saved as %TEMP%\blogdynamoocom.exe (see what they did there?) and has a VirusTotal detection rate of 1/50. Automated analysis tools [1] [2] [3] indicates that the malware phones home to:

62.210.214.106 (OVH, France)
93.89.224.97 (Isimtescil, Cyprus)
87.236.215.151 (OneGbits, Lithuania)


The payload to this is almost definitely the Dridex banking trojan.

Malware spam: "Notice of Underreported Income" / "noreply@hmrc.gov.uk"

The second HMRC spam run of the day..

From:    HM Revenue and Customs [noreply@hmrc.gov.uk]
Date:    1 July 2015 at 11:36
Subject:    Notice of Underreported Income

Taxpayer ID: ufwsd-000004152670UK
Tax Type: Income Tax
Issue: Unreported/Underreported Income (Fraud Application)
Please review your tax income statement on HM Revenue and Customs ( HMRC ).Download your HMRC statement.
Please complete the form. You can download HMRC Form herc

In this case, the link goes to bahiasteel.com/secure_storage/get_document.html however, the payload is Upatre leading to the Dyre banking trojan, as seen in this other spam run today.

Malware spam: "HMRC taxes application with reference L4TI 2A0A UWSV WASP received" / "noreply@taxreg.hmrc.gov.uk"

This fake tax spam leads to malware:

From     "noreply@taxreg.hmrc.gov.uk" [noreply@taxreg.hmrc.gov.uk]
Date     Wed, 1 Jul 2015 11:20:37 +0000
Subject     HMRC taxes application with reference L4TI 2A0A UWSV WASP received

The application with reference number L4TI 2A0A UWSV WASP submitted by you or your
agent to register for HM Revenue & Customs (HMRC) taxes has been received and will
now be verified. HMRC will contact you if further information is needed.

Please download/view your HMRC documents here: http://quadroft.com/secure_storage/get_document.html

The original of this email was scanned for viruses by the Government Secure Intranet
virus scanning service supplied by Vodafone in partnership with Symantec. (CCTM Certificate
Number 2009/09/0052.) On leaving the GSi this email was certified virus free.

Communications via the GSi may be automatically logged, monitored and/or recorded
for legal purposes.d

If you have the correct browser agent (e.g. Internet Explorer 8 on Windows) you will see a "Your document will download shortly.." notice. If you have something else, a fake 404 page will be generated.
The page then forwards to the real HMRC login page but attempts to dump a malicious ZIP from another source at the same time.

In this case, the ZIP file was Document_HM901417.zip which contains a malicious executable Document_HM901417.exe. This has a VirusTotal detection rate of 3/55 (identified as the Upatre downloader).

Automated analysis [1] [2] [3] shows attempted traffic to 93.185.4.90 (C2NET, Czech Republic) and a dropped executable with a random name and an MD5 of ba841ac5f7500b6ea59fcbbfd4d8da32 with a detection rate of 2/55.

The payload is almost definitely the Dyre banking trojan.

Malware spam: "UK Storage Company Invoice" / "UK Storage Company - Gloucester [gloucester@ukstoragecompany.co.uk]"

In the sample I examined, the attachment was GL_Invoice continuation(51741965)_(20150623).doc with a VirusTotal detection rate of 5/55. The payload appears to be the same as these two spam runs also happening today [1] [2].



Malware spam: "Phil" [phil@twococksbrewery.com] / "Statement JUL-2015"

This fake financial spam does not come from Two Cocks Brewery but is instead a simple forgery with a malicious attachment.

Malware spam: "Document Order 534-550719-84513074/1" / "web-filing@companies-house.gov.uk"

In the same I saw, the attachment was named compinfo_534-550719-84513074_1.doc [VT 2/55] which contained this malicious macro [pastebin] which downloads a file from:

http://demaiffe.be/75/85.exe

This is then saved as %TEMP%\silvuple.exe and it has a VirusTotal detection rate of just 1/55. Automated analysis tools [1] [2] [3] indicates malicious traffic to:

78.47.139.58 (Hetzner, Germany)

This IP has been seen a few time recently. Blocking traffic to it is probably a good idea.

The payload is probably the Dridex banking trojan which usually drops via a DLL, although I have not been able to obtain a sample.
