Malware spam: "HSBC SecureMail" / "You have received a secure message"

This fake HSBC email message has a malicious payload:

From:    HSBC SecureMail [HSBCRepresentative_WilliamsBlankenship@hsbc.co.uk]
Date:    16 September 2015 at 13:13
Subject:    You have received a secure message

You have received a secure message Read your secure message by opening the attachment. You will be prompted to open (view) the file or save (download) it to your computer. For best results, save the file first, then open it with Internet Explorer. If you have concerns about the validity of this message, please contact the sender directly. For questions please contact the HSBC Secure Mail Help Desk. First time users - will need to register after opening the attachment. About Email Encryption - http://www.hsbc.co.uk/secureemail HSBC_Payment_87441653 16K

Attacked is a file HSBC_Payment_87441653.zip which in turn contains a malicious executable HSBC_Payment_87441653.exe, this has a VirusTotal detection rate of 4/56.

UPDATE: The Hybrid Analysis report shows network traffic to a familiar Nigerian IP of 197.149.90.166 which I strongly recommend you block. The traffic pattern is indicative of Upatre dropping the Dyre banking trojan.

Malware spam: "Sales Order Acknowledgement - Order No: EF150085 - Your Reference: 14 /Geneva" / reports@officeteam.co.uk

This fake financial spam comes with a malicious payload:

From     "reports@officeteam.co.uk" [reports@officeteam.co.uk]
Date     Fri, 11 Sep 2015 10:39:32 GMT
Subject     Sales Order Acknowledgement - Order No: EF150085 - Your Reference: 14 /Geneva

Please find attached your sales order acknowledgement

Order No: EF150085
Account: PFM895
Your Reference: 14 /Geneva
Web Reference:
Kind Regards
Office Team

In the only sample I have seen there was an attachment SalesOrderAcknowledgement_EF150085.zip which in turn contained a malicious executable SalesOrderAcknowledgement.scr which has a VirusTotal detection rate of 3/55. The Hybrid Analysis report shows that amongst other traffic, it communicates with a familiar Nigerian IP of 197.149.90.166 (Cobranet).

In this case, the payload is Upatre downloading the Dyre banking trojan.

Attached is a file payroll_report.zip which in turn contains a malicious executable payroll_report.scr which has a VirusTotal detection rate of 3/56. The Hybrid Analysis report shows traffic patterns that are consistent with the Upatre downloader and Dyre banking trojan.

In particular, the malware contacts a familiar server at 197.149.90.166 (Cobranet, Nigeria) which you should definitely block traffic to.

Malware spam: "Companies House" [WebFiling@companieshouse.gov.uk]

This spam does not come from Companies House, but is instead a simple forgery with a malicious attachment:

The "case number" is random, and is reflected in the name of the attachment (in this case Case_0676414.zip) which in turn contains a malicious executable Case_0043258.scr which has an icon to make it look like a PDF file.

This executable has a detection rate of 4/56. The Hybrid Analysis report shows that it communicates with 197.149.90.166 (Cobranet, Nigeria) which has been seen handling malicious traffic for the past couple of weeks. The payload is Upatre/Dyre.

Malware spam: "Complaint of your Internet activity"

This spam comes with a malicious attachment:

From:    Margret Kuhic
Date:    1 September 2015 at 16:10
Subject:    Complaint of your Internet activity

This is a complaint notification. Full details attached. Please notify us within 24 hours with taken actions.

Margret Kuhic
Dynamic Communications Agent
T: 1-679-732-5379
F: 100.173.9045

All the sames I have seen have a corrupt attachment which is Base 64 encoded, it is possible that other people might receive a valid attachment though. The attachment was meant to be 723296788_Marquardt-Bailey_Margret Kuhic.zip containing the malicious executable june_stiedemannmolestiae.et.exe which has a VirusTotal detection rate of 2/56.

This Hybrid Analysis report shows it to be just another variant of Update / Dyre with the same characteristics as the malspam seen earlier today, sending traffic to an IP that I suggest you block or monitor:

197.149.90.166 (Cobranet, Nigeria)

Some other subjects spotted include:
Complaint notification 50646
Infringement of your Internet activity
Infringement notification 51494

Malware spam: "Private message notification 41447" / "Adrien Abbott"

This spam comes with a malicious attachment:

From:    Adrien Abbott

Subject:    Private message notification 41447

You've received a private message. Please open the attached to view it.

I have only seen a single sample of this spam, and the attachment was not formatted properly making it harmless, however other variants could be more dangerous. If properly decoded, the attachment should have been named 89867740_Torphy and Sons_Adrien Abbott.zip containing a malicious executable jodie_okonofficia-quo.exe. This executable has a VirusTotal detection rate of just 2/56, the Hybrid Analysis report shows network activity consistent with this being Upatre dropping the Dyre banking trojan, with communications made to:

197.149.90.166 (Cobranet, Nigeria)

..which is an IP that has been used several time for this sort of attack recently and is worth blocking. The report details other IP addresses too, but this seems to be the key one to block or monitor.

Malware spam: "Payslip for period end date 27/08/2015" / "noreply@fermanagh.gov.uk"

This spam does not come from Fermanagh District Council. Of course it doesn't. It is instead a simple forgery with a malicious attachment:

From:    noreply@fermanagh.gov.uk [noreply@fermanagh.gov.uk]
Date:    27 August 2015 at 12:28
Subject:    Payslip for period end date 27/08/2015

Dear administrator

Please find attached your payslip for period end 27/08/2015

Payroll Section

Attached is a file payroll.zip which contains a malicious executable payroll.scr - or it would have done, but in my case the email was malformed and the archive was not attached properly.

This executable has a detection rate of 3/56 and the Hybrid Analysis report indicates that it sends traffic to a server at 197.149.90.166 (Cobranet, Nigeria) which has been used in a few recent attacks and is definitely worth blocking.

Fake fax spam spoofs multiple senders, has malicious payload

This fake fax spam comes from random senders - company names and attachment names vary from spam to spam.

From: "Heaney, Vandervort and Hilll"
Subject: Fax #AhnxlQ8 from Donny Kub
Date: Wed, 26 Aug 2015 14:02:30 +0000

You have a fax.
Data sent: Wed, 26 Aug 2015 14:03:30 +0000
TO: info@victimdomain.com

*********************************
We are a new fax delivery service - Heaney, Vandervort and Hilll.
Our company develops rapidly and services remain fastest and open to everyone.
As our slogan goes: "Fast. Cheap. Best quality."
*********************************

Attached is a ZIP file combining various elements from the spam (for example, in this case it was fax_AhnxlQ8_Heaney, Vandervort and Hilll_Donny Kub.zip). This contains a malicious executable (e.g. Invoice Lake Janeview.exe) which currently has a 2/56 detection rate at VirusTotal.

The Hybrid Analysis report shows it phoning home to:

197.149.90.166/260822U/Yd1D3h1R87/0/61-SP1/0/FDMBEFJBMKBEMM
197.149.90.166/260822U/Yd1D3h1R87/41/5/42/FDMBEFJBMKBEMM

This pattern marks the malware out as being Upatre/Dyre.  197.149.90.166 is an IP address belonging to Cobranet in Nigeria which was also used in a similar attack yesterday.

Malware spam: "UPDATE_VACATIONS_SCHEDULE_09_2015.pdf" via sugarsync.com

 This fake Dropbox email leads to malware, hosted on the sharing service sugarsync.com.

From:    June Abel via Dropbox [no-reply@dropbox.com]
Date:    25 August 2015 at 12:59
Subject:    June Abel shared "UPDATE_VACATIONS_SCHEDULE_09_2015.pdf" with you

June used Dropbox to share a file with you! Click here to download. © 2015 Dropbox

I have seen three different samples with different download location:

https://www.sugarsync.com/pf/D3941255_827_052066225?directDownload=true
https://www.sugarsync.com/pf/D160756_82_6104120627?directDownload=true
https://www.sugarsync.com/pf/D2694666_265_638165437?directDownload=true

In each case, the binary downloaded is identical and has a VirusTotal detection rate of 3/55. Analysis is pending, but the payload appears to be the Dyre banking trojan.

UPDATE: 
The Hybrid Analysis report shows traffic to 197.149.90.166 (Cobranet, Nigeria) which I recommend you block.

Malware spam: "Email from Transport for London" / "noresponse@cclondon.com"

The attachment name seems to vary, in the samples I have seen there is 7887775.zip, 0174458.zip and rather oddly [?var=partorderb].zip. From these I have recovered two malicious samples with a VirusTotal detection rate of 6/56 and 1/57. These two Hybrid Analysis reports [1] [2]  show the malware connecting to various malicious and non-malicious IPs, but in particular we see a traffic pattern like this:

93.185.4.90:12326/2008uk77/jI7tL6q34q/0/61-SP1/0/FDMBEFJBMKBEMM
93.185.4.90:12326/2008uk77/jI7tL6q34q/41/5/42/FDMBEFJBMKBEMM

These GET requests are a characteristic of Upatre/Dyre. 93.185.4.90 is allocated to C2NET, Czech Republic and I strongly recommend that you block it.

Those Hybrid Analysis reports also identify some botnet IPs and dropped files, which I suggest that you study if interested.

Malware spam: "Sleek Granite Computer" / "saepe 422-091-2468.zip" / "nulla.exe"

What the heck is a Sleek Granite Computer? As clickbait it is kind of weird.. but perhaps interesting enough to get people to click on the malicious attachment is comes with.

For Your kind review we enclose here the business plan and all the related documents.
Please send us an e-mail in case You have any comments or proposed changes.
According to our calculations the project will start bringing profit in 6 months.

The only sample of this I had was malformed and the attachment wasn't attached properly. However, if properly formatted it would have been named saepe 422-091-2468.zip and it contains a malicious executable named nulla.exe.

This has a VirusTotal detection rate of 4/55 with Sophos identifying it as a variant of Upatre. The Hybrid Analysis report shows a typical Upatre / Dyre traffic pattern to:

195.154.241.208:12800/0608us12/6FsvE66Gy1/0/61-SP1/0/FDMBEFJBMKBEMM
195.154.241.208:12800/0608us12/6FsvE66Gy1/41/2/18/FDMBEFJBMKBEMM

This IP address belongs to Online SAS in France who seem to have hosted quite a bit of this stuff recently, the hostname identifies it as belonging to poneytelecom.eu. Traffic is also spotted to:

37.57.144.177 (Triolan / Content Delivery Network, Ukraine)
95.143.141.50 (LTnet, Czech Republic)

There is also non-malicious traffic to icanhazip.com to identify the IP address of the infected machine. This is worth monitoring though as it is a potential indicator of compromise. The payload is almost definitely the Dyre banking trojan.

Recommended blocklist:
195.154.241.208
37.57.144.177
95.143.141.50

Attached is a Word document with a malicious macro. The Hybrid Analysis report shows it downloading components from several locations, but doesn't quite catch the malicious binary being downloaded from:

http://umontreal-ca.com/word/word.exe

This has a VirusTotal detection rate of 2/55.

umontreal-ca.com (89.144.10.200 / ISP4P, Germany) is a known bad domain. Other analysis is pending, however the payload is likely to be the Dyre banking trojan.

This Hybrid Analysis report shows traffic to the following IPs:

67.222.202.183 (Huntel.net, US)
195.154.163.4 (Online SAS, France)

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.

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:

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.

Although the numbers and some other details change in the spam messages, in all cases the download location has been from a legitimate but hacked site at:

breedandco.com/fileshare/FAX-1400166434-707348006719-154.zip

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):

93.185.4.90:12325/ETK7/<MACHINE_NAME>/0/51-SP3/0/GKBIMBFDBEEE
93.185.4.90:12325/ETK7/<MACHINE_NAME>/41/5/1/GKBIMBFDBEEE

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.

The malware reaches out to some other malicious IPs (mostly parts of a botnet):

93.185.4.90 (C2NET, Czech Republic)
62.204.250.26 (TTNET, Czech Republic)
76.84.81.120 (Time Warner Cable, US)

199.255.132.202 (Computer Sales & Services Inc., US)
208.123.135.106 (Secom Inc, US)

Among other things, the malware drops a file XGwdKLWhYBDqWBb.exe [VT 10/55] and vastuvut.exe [VT 6/55].

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.

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.

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

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.
