Malware spam: "Currys PC World [noreply_stores@currys.co.uk]" / "Your eReceipt"

This very convincing-looking email is not from Currys PC World but is instead a simple forgery with a malicious attachment.

From:    Currys PC World [noreply_stores@currys.co.uk]
Date:    17 December 2015 at 08:27
Subject:    Your eReceipt

There are a few different versions of the attachment with fairly low detection rates [1] [2] and analysis of those two examples shows that the macro downloads from the following locations:

old.durchgegorene-weine.de/65dfg77/kmn653.exe
www.riucreatives.com/65dfg77/kmn653.exe

The payload here is the Dridex banking trojan and is identical to the one found here and here.

Malware spam: "James Wheatley sent you an document file!" / wheatjam@gmail.com

Poor old James Wheatley is a real person who must have pissed off some Russians somewhere (perhaps it is a Joe Job). This fake WhatsApp spam in his name has a malicious attachment.

There seem to be a few variants of the attachment, these have a detection rate of about 4/55 [1] [2] and analysis of those two examples [3] [4] download a malicious binary from:

www.nz77.de/65dfg77/kmn653.exe

This payload is the same as the one found in this spam run earlier today.

Malware spam: "12/16 A Invoice"

This fake financial spam leads to malware:

From:    Kelley Small
Date:    17 December 2015 at 08:39
Subject:    12/16 A Invoice

Hi,
Please find attached a recharge invoice for your broadband.

Many thanks,
Kelley Small

The sender's name is randomly generated, for example:

Harris Page
Leonel Kramer
Gracie Fuentes
Earlene Aguirre
Jerri Whitfield
Art Keith
Freeman Gregory
Moses Larson
Leanna Fletcher

There is an attachment in the format invoice36649009.doc where the number is randomly generated. This comes in at least six different versions but they do not appear to be uniquely generated (VirusTotal results [1] [2] [3] [4] [5] [6] [7]). Detection rates are close to zero.

The Malwr reports for those documents is a mixed bag [1] [2] [3] [4] [5] [6] [7] is a mixed bag, but overall they spot data being POSTed to:

179.60.144.18/chicken/bacon.php
91.203.5.169/chicken/bacon.php

Sources tell me there is another download location of:

195.191.25.145/chicken/bacon.php

Those IPs are likely to be malicious and belong to:

179.60.144.18 (Veraton Projects Ltd, Netherlands)
91.203.5.169 (Denis Pavlovich Semenyuk / TutHost, Ukraine)
195.191.25.145 (Hostpro Ltd, Ukraine)


They also GET from:

A file karp.exe  is dropped with an MD5 of 1fbf5be463ce094a6f7ad345612ec1e7 and a detection rate of 3/54. According to this Malwr report this communicates with:

80.96.150.201 (SC-Nextra Telecom SRL, Romania)

It's not clear what the payload is, but probably some sort of banking trojan such as Dridex.

UPDATE 12/1/16 

The same message format is being used for another attack with a slightly different payload, which is the same as used in this spam run.

Malware spam: "Your account has a debt and is past due" leads to Teslacrypt

This fake financial spam comes with an interesting error in the part that is meant to randomly-generate the dollar amount:

From:    Frances Figueroa
Date:    16 December 2015 at 17:22
Subject:    Your account has a debt and is past due

Dear Customer,

Our records show that your account has a debt of $345.{rand(10,99)}}. Previous attempts of collecting this sum have failed.

Down below you can find an attached file with the information on your case.

The value, sender's name and attachment name are randomly generated. The attachment is named in the format SCAN_INVOICE_79608749.zip which contains a malicious script that attempts to download Teslacrypt ransomware from the following locations:

whatdidyaysay.com/80.exe?1
iamthewinnerhere.com/80.exe?1

This has a VirusTotal detection rate of 3/54 and an MD5 of 5c2a687f9235dd536834632c8185b32e. Those download locations have been registered specifically for this purpose (they are not hacked sites) and are hosted on:

Malware spam: "Unpaid Invoice from Staples Inc., Ref. 09123456, Urgent Notice" leads to Teslacrypt

This fake financial spam is not from Staples or Realty Solutions but is instead a simple forgery with a malicious attachment.

From:    Virgilio Bradley
Date:    16 December 2015 at 14:37
Subject:    Unpaid Invoice from Staples Inc., Ref. 09846839, Urgent Notice

Dear Valued Customer,

This letter is a formal notice to you taking in consideration the fact that you are obligated to repay our company the sum of $767,90 which was advanced to you from our company on November 21st, 2015.
You now have two options: forward your payment to our office by January 17, 2016 or become a party in a legal action. Please be advised that a judgment against you will also damage your credit record.

The names, amounts and reference numbers change from email to email. The attachment has the same name of the reference (e.g. invoice_09846839_copy.doc) but despite this I have only seen one version with a VirusTotal detection rate of just 1/55.

According to this Malwr report, the macro in the document downloads a binary from:

iamthewinnerhere.com/97.exe

This appears to be Teslacrypt ransomware and it has a detection rate of 5/53. Unlike some other malware, the domain iamthewinnerhere.com has been registered specifically to host this malware, and is located on:

185.69.152.145 (Hosting Ukraine Ltd, Ukraine)

Domain registration scan: cn-registry.net / "Huabao Ltd"

Subject:    "petroldirect"

Dear CEO,

(If you are not the person who is in charge of this, please forward this to your CEO, because this is urgent, Thanks)

We are a Network Service Company which is the domain name registration center in Shanghai, China.

We received an application from Huabao Ltd on December 14, 2015. They want to register " petroldirect " as their Internet Keyword and " petroldirect .cn "、" petroldirect .com.cn " 、" petroldirect .net.cn "、" petroldirect .org.cn " 、" petroldirect .asia " domain names etc.., they are in China and Asia domain names. But after checking it, we find " petroldirect " conflicts with your company. In order to deal with this matter better, so we send you email and confirm whether this company is your distributor or business partner in China or not?

 

Best Regards,

  Jim

In fact, there is no Huabao Ltd - it's just a made-up name that the scammers use to try to persuade you into buying some overpriced and worthless domains. Nobody is interested in buying these domains, and no domain registrar would contact you before registration in any case as it is not the responsibility of registrar to do so*.

I certainly don't recommend forwarding this to your CEO, as many CEOs will not understand the scam and may fall for it. If you do forward it, make you that you point out that this is a scam.

This scam has been around for so long, that I even made a video about it..

These following domains are all variations of the same rogue Chinese registrar:

cnregistry.net
cn-registry.net
cnwebregistry.net
cn-registry.com

Malware spam: "Rockspring Remittance Advice - WIRE"

If you are not seeing your addenda information in your bank reporting you may have to contact your local bank representative.

Accounts Payable

Attached is a malicious document with a random name. I have only seen one sample so far with a VirusTotal detection rate of 3/55. The Malwr report indicates that same behaviour as this earlier spam run  which is dropping Nymaim ransomware.

Tainted network: Dmitry Shestakov / vds24.net on OVH

vds24.net (apparently belonging to "Dmitry Shestakov ") is a Russian reseller of OVH servers that has come up on my radar a few times in the past few days [1] [2] [3] in connection with domains supporting Teslacrypt malware and acting as landing pages for the Angler exploit kit.

Curious as to what was hosted on the vds24.net I set about trying to find out their IP address ranges. This proved to be somewhat difficult as they are spread in little chunks throughout OVH's IP space. I managed to identify:

5.135.58.216/29
5.135.254.224/29
51.254.10.128/29
51.254.162.80/30
51.255.131.64/30
149.202.234.116/30
149.202.234.144/30
149.202.234.188/30
149.202.237.68/30
176.31.24.28/30
178.32.95.152/29
178.33.200.128/26

Then using a reverse DNS function, I looked up all the domains associated with those ranges (there were a LOT) and then looked the see which were active plus their SURBL and Google ratings. You can see the results of the analysis here [csv].

There may well be legitimate domains in this range, but out of 1658 domains identified, 1287 (77.6%) are flagged by SURBL as being spammy. Only 11 (0.7%) are identified as malicious, but in reality I believe this to be much higher.

In particular, the following IP ranges seem to be clearly bad from those ratings:

51.254.10.131
51.254.162.81
51.255.131.66
51.255.142.101
149.202.234.190
149.202.237.68
178.33.200.138

I can see 61 active IPs in the vds24.net range, so perhaps it is only a small proportion. However, depending on your network stance, you may want to consider blocking all the IP ranges specified above just to be on the safe side.

UPDATE

One additional range has come to light, connected with the Dridex banking trojan:

51.254.51.176/30

Malware spam: "Invoice Attached" / "Accounting Specialist| Bank of America, N.A., Cabot Oil & Gas Corp."

This fake financial spam has a malicious attachment:

From:    Ernestine Harvey
Date:    15 December 2015 at 11:34
Subject:    Invoice Attached

Good morning,

Please see the attached invoice and remit payment according to the terms listed at the bottom of the invoice. If you have any questions please let us know.

Thank you!

Mr. Ernestine Harvey
Accounting Specialist| Bank of America, N.A., Cabot Oil & Gas Corp.

The sender name varies randomly, except in the email they are all signed "Mr." even if they have female names, for example:

Mr. Colleen Sheppard
Mr. Joel Small
Mr. Esther Gates
Mr. Devin Joyce
Mr. Todd Robertson

The attachments are named in the format invoice_12345678_scan.doc - the filenames are randomly-generated and indeed every attachment seems to be unique. Typical VirusTotal detection rates are around 3/54, and the macro looks something like this.

An analysis of five of the attachments [1] [2] [3] [4] [5] shows attempted downloads from:

modern7technologiesx0.tk/x1656/dfiubgh5.exe
forbiddentextmate58.tk/x1656/ctruiovy.exe
temporary777winner777.tk/x1656/fdgbh44b.exe
former12futuristik888.tk/x1656/fdgjbhis75.exe

Note that these are all .TK domains.. and they are all hosted on exactly the same server of 31.184.234.5 (GTO Ltd, Montenegro). A look at VirusTotal's report for that IP gives another malicious domain of:

servicexmonitoring899.tk

I would suggest that the entire 31.184.234.0/24 range looks pretty questionable.

Anyway, the downloaded binary has a VirusTotal detection rate of 4/55 and the comments indicate that rather surprisingly this is the Nymaim ransomware. The Hybrid Analysis indicates network traffic to xnkhfbc.in on 200.195.138.156 (Szabo & Buhnemann, Brazil). But in fact that domain seems to move around a lot and has recently been seen on the following IPs:

41.224.12.178 (Orange Tunisie Internet, Tunisia)
51.255.59.248 (OVH, France)
78.107.46.8 (Corbina Telecom, Russia)

There are probably other version of the document with different download locations. This malicious executable has a detection rate of 2/54 and between them these three reports [1] [2] [3] indicate malicious traffic to:

199.7.136.84 (Megawire Inc, Canada)

Malware spam: "Israel Burke" / "BCP Transportation, Inc."

Dear Customer:

We greatly appreciate your business!

Israel Burke
BCP Transportation, Inc.

I have only seen one sample of this, it is possible that the company name and sender names are randomly generated. The attachment in this case was named invoice_scan_76926455.doc and has a detection rate of 3/55.

Despite the name, this is not a Word document but is an XML document [pastebin] containing ActiveMIME data. The Malwr report for this indicates network traffic to:

109.234.34.224 (McHost.Ru, Russia)
80.96.150.201 (SC-Nextra Telecom SRL, Romania)

That Malwr report shows a dropped binary named qqqew.exe which has a VirusTotal detection rate of 5/55.

I am not certain of the payload, but I suspect that this Word document is dropping Upatre leading to the Dyre banking trojan.

This letter was sent to you as a formal notice that you are obligated to repay our company the sum of 2,760$ which was advanced to you from our company on October 16, 2015.
Please, find the invoice enclosed down below.

This amount must be repaid until the date of maturity to payment obligation, December 28, 2015 and you have failed to repay our company the same despite repeated requests for this payment.

The sender's name is randomly-generated but is always female. Also random are the order number and value, and there is an attachment in the format invoice_12345678_scan.zip that matches the reference in the document.

Inside that ZIP file is a uniquely generated .JS file in the format invoice_XXXXXX.js or invoice_copy_XXXXXX.js which is highly obfuscated (like this) and deobfuscates to something like this.

The various versions of the macro attempts to download a binary from the following location:

I think they started spamming before the domain records could be pushed out fully. Shame.

Nameservers are DNS1.DONALDDUCKS.IN and DNS2.DONALDDUCKS.IN on 93.189.42.21 (NTCOM, Russia) and 178.33.200.177 (Dmitry Shestakov, Belize / OVH, France) respectively.

Looking at the nameservers, I can see that the following malicious domains are part of the same cluster, and I recommend you block all of them:

gammus.com
miracleworld1.com
soft2webextrain.com

Although I have not been able to acquire the payload, it is almost definitely Teslacrypt.

UPDATE

An updated version of the script is being spammed out that looks like this when deobfuscated. This attempts to download Teslacrypt from the following URLs:

firstwetakemanhat.com/91.exe?1
miracleworld1.com/91.exe?1

This has a detection rate of 4/55. firstwetakemanhat.com was registered just today and is hosted on:


193.150.0.78 (PE Govoruhin Vitaliy Sergeevich, Russia)
84.200.69.60 (Ideal-Hosting UG, Germany)


Nameservers are DNS1.GOGODNS.RU and DNS2.GOGODNS.RU which are hosted on the same two IPs.

The Malwr report shows more details, however this is my recommended blocklist (updated):

Curiously, the bad guys have gone as far as to include a fake header to make it look like a fax:

X-Mailer: ActiveFax 3.92

 
Attached is a file fax00163721.xls which is fairly obviously not a PDF document. So far I have seen two versions of this with a detection rate of 6/55 [1] [2] and which these Malwr reports [3] [4] indicate download a malicious binary from:

exfabrica.org/437g8/43s5d6f7g.exe
test-cms.reactive.by/437g8/43s5d6f7g.exe

This binary has a detection rate of 0/54. That VirusTotal report and this Hybrid Analysis both show traffic to:

199.7.136.84 (Megawire, Canada)

This malware is likely to be Dridex. Given that it is similar to the one found here,  I would recommend blocking network traffic to:

I've blocked traffic to 176.103.48.0/20 for two years with no ill-effects, it seems to be a particularly bad network. There may be a few legitimate sites hosted in these ranges, they would mostly be Russian.. so if you don't usually visit Russian websites then the collateral damage might be acceptable.

Malware spam: "Invoice #66626337/BA2DEB0F" leads to Teslacrypt

I have only seen one sample of this fake invoice spam, so it is possible that the invoice references and sender names are randomly generated.

From:    Jarvis Miranda
Date:    11 December 2015 at 08:25
Subject:    Invoice #66626337/BA2DEB0F

Dear Client,

Our finance department has processed your payment, unfortunately it has been declined.
Please, double check the information provided in the invoice down below and confirm your details.

Thank you for understanding.

In the sample I saw, the attached file was named SCAN_invoice_66626337.zip which contained a malicious javascript [pastebin] with a VirusTotal detection rate of 5/54. When deobfuscated it becomes a bit clearer that it is trying to download a binary from:

soft2webextrain.com/87.exe?1
46.151.52.231/87.exe?1

This behaviour can be seen in these automated reports [1] [2]. The downloaded executable has a detection rate of 6/55 and an MD5 of 56214f61a768c64e003b68bae7d67cd2. This Malwr report gives a clearer indication of what the binary is doing, attempting to pull information from:

kochstudiomaashof.de

The screenshots indicate clearly that this is ransomware, specifically Teslacrypt.

Note that the soft2webextrain.com domain is on the same server as softextrain64.com seen yesterday, so 185.118.64.182 (CloudSol LLC, Russia) can be considered to be malicious.


UPDATE
I didn't spot originally that the "soft2webextrain.com" website is multhomed with another IP address on 149.202.234.190 which is an OVH IP allocated to a customer "Dmitry Shestakov" an which forms a small block of 149.202.234.188/30 which is probably also worth blocking.

UPDATE 2
I made an error with one of the IP addresses and specified 185.118.64.183 and it should have been 185.118.64.182.

Recommended blocklist:

life.1pworks.com/76t7h/76gjk.exe

There will probably be other versions of the document with different download locations. This executable has a detection rate of 2/54 and according to this Malwr report it contacts:

136.145.86.27 (University Of Puerto Rico, Puerto Rico)

Other analysis is pending, in the meantime I recommend that you block traffic to that IP. The payload is probably the Dridex banking trojan.

There sender's name and the reference numbers change in each version. Attached is a file copy_invoice_11004118.zip which in turn contains a malicious script [VT 5/54] which in the sample I investigated was named invoice_iU9A2Y.js. When deofuscated it looks like this.

The Malwr report for that script shows it downloading from:

softextrain64.com/86.exe?1

The script itself shows an alternate location of:

46.151.52.197/86.exe?1

This has a VirusTotal detection rate of 3/55. A Malwr report on just the executable plus this Hybrid Analysis report shows it connecting to:

gjesdalbrass.no

It also tries to identify the IP address of the host by connecting to http://myexternalip.com/raw which is a benign service that you might consider to be a good indicator of compromise.

You can see in the screenshots of that Malwr report that this is ransomware, specifically Teslacrypt.

Recommended blocklist:
gjesdalbrass.no

Malware spam: "EXB (UK) Ltd Invoice" / "Sales [sales@exbuk.co.uk]"

This fake financial spam does not come from EXB (UK) Ltd but is instead a simple forgery with a malicious attachment.

From:    Sales [sales@exbuk.co.uk]
Date:    8 December 2015 at 12:03
Subject:    EXB (UK) Ltd Invoice

Dear Sirs,

Please find attached our invoice, Thank you for your order

Best Wishes

EXB (UK) Ltd

Attached is a Word document named Invoice 1195288 from EXB (UK) Limited.doc which comes in at least three different versions (VirusTotal results [1] [2] [3]) and which contain a complex macro [pastebin] that fails to run in automated analysis tools [4] [5] [6] [7] [8] [9].

The payload (if it works) is likely to be the Dridex banking trojan.

UPDATE
According to the comments on this post plus some other sources, the macros in these documents download from:

cabezasdealambre.eu/76re459/98uy76t.exe
mfmanastacio.com/76re459/98uy76t.exe
216.119.110.104/76re459/98uy76t.exe

That payload is identical to the one found in this earlier spam run.
