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)

200.195.138.156 (Szabo & Buhnemann Ltda, Brazil)
210.150.126.225 (HOSTING-NET, Japan)

Malware spam: "Invoice for Voucher ACH-2-197701-35" / "Reservations [res@affordablecarhire.com]"

This fake financial spam does not come from Affordable Car Hire but is instead a simple forgery with a malicious attachment.

ACH-2-197701-35-invoice.xls 116K

I have only seen a single sample, with an attachment ACH-2-197701-35-invoice.xls which has a VirusTotal detection rate of 3/54. According to this Malwr report, it downloads a malicious binary from:

usahamanfaat.com/8iy45323f/i87645y3t23.exe

The payload here is the Dridex banking trojan, and it is identical to the one found in this spam run.

Malware spam: "Order PS007XX20000584" / "Nicola Hogg [NHogg@pettywood.co.uk]"

This rather brief spam does not come from Petty Wood but is instead a simple forgery with a malicious attachment:

From:    Nicola Hogg [NHogg@pettywood.co.uk]
Date:    15 December 2015 at 10:14
Subject:    Order PS007XX20000584

There is no body text, but instead there is an attachment PS007XX20000584 - Confirmation with Photos.DOC which has a VirusTotal detection rate of 5/55 and it contains a malicious macro [pastebin] which (according to this Malwr report) downloads a binary from:

kutschfahrten-friesenexpress.de/8iy45323f/i87645y3t23.exe

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)
221.132.35.56 (Ho Chi Minh City Post And Telecom Company, Vietnam)

The payload here is likely to be the Dridex banking trojan.

Dear Valued Customer,

It seems that your account has a past due balance of $263,49. Previous attempts to collect the outstanding amount have failed.

Please remit $263,49 from invoice #89044096 within three days or your account will be closed, any outstanding orders will be cancelled and this matter will be referred to a collection agency.

The payment notice is enclosed to the letter down below.

Attached is a file invoice_89044096_scan.doc which has a VirusTotal detection rate of 2/54, and which contains this malicious macro [pastebin] which attempts to download a binary from the following location:

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

This fake invoice comes with a malicious attachment:

From:    Israel Burke [BurkeIsrael850@business.telecomitalia.it]
Date:    14 December 2015 at 15:00
Subject:    Israel Burke

Dear Customer:

Attached please find an invoice(s) for payment.  Please let us know if you have any questions.

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.

Subject:    Your order #25333445

Dear Valued Customer,

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.

Thank you in advance for your prompt attention to this matter. We look forward to your remittance. If you have any questions, please do not hesitate to contact us.

Sincerely,
Giuseppe Sims
11 Money Way
Pittsburgh, PA 15226

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:

miracleworld1.com/80.exe?1

I cannot get this to resolve at the moment, it turns out that the domain was only registered today.

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):
193.150.0.78

Malware spam: "Invoice 14 12 15" / "THUNDERBOLTS LIMITED [enquiries@thunderbolts.co.uk]"

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.

Attached is a file XACWL-15DEC12-120106.DOC which I have only seen one variant of so far, with a VirusTotal detection rate of 6/54. According to the Malwr analysis, it downloads a file from:

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.

Fake "Fretter Inc" spam leads to Teslacrypt ransomware

This email claims to be from the long-dead retailer Fretter Inc, but it is not. Instead it comes with a malicious attachment leading to the Teslacrypt ransomware.

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.

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.

Malware spam: "Updated Statement - 2323191" / "David Lawale [David.Lawale@buildbase.co.uk]"

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

Attached is a file 151124142451_0001.xls which I have seen come in two versions so far (VirusTotal results [1] [2]). Analysis of this malware is pending, but it most likely leads to the Dridex banking trojan.

UPDATE 1
Automated analysis is inconclusive [1] [2] [3] [4] [5] [6]. It is possible that there is an error in the macro.

UPDATE 2
According to the comments in this post and also some other sources, the the macros download from:

gulteknoofis.com/76re459/98uy76t.exe
kinderdeszorns.de/76re459/98uy76t.exe
agencjareklamowalodz.com/76re459/98uy76t.exe

This has a detection rate of 4/55. According to these reports [1] [2] [3] and other sources, the malware phones home to:

216.189.52.147 (High Speed Web/Genesis 2 Networks, US)
23.113.113.105 (AT&T, US)
221.132.35.56 (Ho Chi Minh City Post and Telecom Company, Vietnam)

Malware spam: "Your receipt from Apple Store, Manchester Arndale" / "manchesterarndale@apple.com"

This fake receipt does not come from an Apple Store, but is instead a simple forgery with a malicious attachment:

From:    manchesterarndale@apple.com
Date:    7 December 2015 at 09:43
Subject:    Your receipt from Apple Store, Manchester Arndale

Thank you for shopping at the Apple Store.

Attached is a file emailreceipt_20150130R2155644709.xls which in the sample I analysed has a VirusTotal detection rate of 6/53.

According to this Malwr report, the attachment downloads a malicious binary from:

steveyuhas.com/~steveyuhas/87tr65/43wedf.exe

This has a VirusTotal detection rate of precisely zero.  Those reports indicate network traffic to:

23.113.113.105 (AT&T Internet Services, US)

This is the same IP as seen in this earlier spam run, and I strongly recommend that you block it. The payload is likely to be the Dridex banking trojan.

I have seen only one sample of this spam with an attachment with a somewhat interesting name of C:\\Users\\HOLLY~1.HUM\\AppData\\Local\\Temp\\Inv_107666_from_DATANET.CO..xls which saves on my computer as C__Users_HOLLY~1.HUM_AppData_Local_Temp_Inv_107666_from_DATANET.CO..xls. This contains this malicious macro [pastebin] and has a VirusTotal detection rate of 3/55.

According to this Malwr report and this Hybrid Analysis the XLS file downloads a malicious binary from :

encre.ie/u5y432/h54f3.exe

There will probably be other versions of this document downloading from other locations too. This has a VirusTotal detection rate of just 1/55 and that report plus this Malwr report  indicate malicious network traffic to:

94.73.155.12 (Cizgi Telekomunikasyon Anonim Sirketi, Turkey)
78.47.66.169 (Hetzner, Germany)
