Malware spam: "Blocked Transaction. Case No 19706002" leads to Teslacrypt

This fake financial transaction has a malicious attachment:

From:    Judy brittain
Date:    14 March 2016 at 08:12
Subject:    Blocked Transaction. Case No 19706002

The Automated Clearing House transaction (ID: 19706002), recently initiated from your online banking account, was rejected by the other financial institution.

Canceled ACH transaction
ACH file Case ID: 09293
Transaction Amount: 607,89 USD
Sender e-mail: brittainJudy056@panick.com.ar
Reason of Termination: See attached statement

The sender's name, references and dollar amounts vary from message to messages. The attachment names are randomly-generated (the format seems the same as this) containing either one or four malicious scripts. According to this analysis the scripts download from:

ohelloguyzzqq.com/85.exe?1

Although the infection mechanism seems the same as this spam run, the MD5 of the dropped executable is now 57759F7901EBA73040597D4BA57D511A with a detection rate of 2/55. This is Teslacrypt ransomware, and I recommend that you block traffic to the IP addresses listed here.

Malware spam: "Debt #85533 , Customer Case Nr.: 878" leads to Teslacrypt

The details in these spam messages vary, with different reference numbers, sender names and dollar amounts. They all have malicious attachments, however.

Subject:    Debt #85533 , Customer Case Nr.: 878

Dear Customer,

Despite our constant reminders, we would like to note that the mentioned debt #85533 for $826,87 is still overdue for payment.

We would appreciate your cooperation on this case and ask you to make the payment as soon as possible.

Unless the full payment is received by April 1st, 2016 this case will be transferred to the debt collection agency, will seriously damage your credit rating.
Please, find the attachment enclosed to the letter below.

We hope on your understanding.

Kind regards,

• finance_
• warning_letter_
• report_
• transaction_

These appear [1] [2] to download a malicious binary from one of the following locations:

ohelloguyff.com/70.exe
ohelloguyzzqq.com/85.exe?1

Of these, only the 85.exe download is working for me at the moment which is Teslacrypt ransomware. This has a detection rate of just 1/56.

The download locations have the following IP addresses:

185.35.108.109 (DA International Group Ltd, Bulgaria)

Malware spam: "Urgent Notice # 78815053" leads to Teslacrypt

This spam comes from random senders, and has random references, dollar amounts and attachment names:

From:    Donnie emily
Date:    12 March 2016 at 14:01
Subject:    Urgent Notice # 78815053

Dear Customer!

According to our data you owe our company a sum of $452,49. There are records saying that you have ordered goods in a total amount of $ 452,49 in the third quarter of 2015.

Invoice has been paid only partially. The unpaid invoice #78815053 is enclosed below for your revision.

We are writing to you, hoping for understanding and in anticipation of the early repayment of debt.

Please check out the file and do not hesitate to pay off the debt.

Otherwise we will have to start a legal action against you.

Regards,

Attached is a randomly-named ZIP file, in the sample I have seen they begin with:

• letter_
• confirm_
• access_
• unconfirmed_operation_
• operation_
• details_

..plus a random number. There may be other formats. Inside is a malicious script beginning with:

• details_
• post_
• mail_

..plus a random string of characters. I have seen six versions of this script, I do not know how many there are in total. VirusTotal results show detection rates between 4 and 7 out of 57 [1] [2] [3] [4] [5] [6] and automated analysis tools [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] show the script attempting to download a binary from:

bonjovijonqq.com/69.exe?1
bonjovijonqq.com/80.exe?1

This is Teslacrypt ransomware, although it is possible that some variants of this message may drop Locky. Both these binaries are slightly different (VirusTotal results [19] [20]) and they appear to phone home to:

vtechshop.net/wcspng.php
sappmtraining.com/wp-includes/theme-compat/wcspng.php
shirongfeng.cn/images/lurd/wcspng.php

It also attempts to contact the domain multibrandphone.com but that was not resolving at the time of analysis. It also appears to phone home to:

31.184.196.78 (Petersburg Internet Network Ltd, Russia)
91.234.32.192 (FOP Sedinkin Olexandr Valeriyovuch, Russia)

Dear [redacted],

We have received this documents from your bank, please review attached documents.

Yours sincerely,

______________________________________________________________________
This email has been scanned by the Symantec Email Security.cloud service.

Attached is a ZIP file named in the format payment_doc_507586.zip, containing a randomly named script containing one of the following strings plus a random number and also it seems a # sign at the end of some.

• Post_Shipment_Confirmation_id
• Post_Shipment_Label_id
• q.
• Post_Shipment_Case_id
• Post_Tracking_Confirmation_id
• Post_Parcel_Confirmation_id

Detection rates for these scripts are all zero at the moment [1] [2] [3]. A Malwr analysis of some of the samples [4] [5] [6] shows download locations at:

nro.gov.sd/23r35y44y5
nobilitas.cz/0954t4h45

There are probably other download locations. The dropped binaries are actually different [1] [2] and both look like Locky ransomware. The C2s to block are the same as found in this earlier Locky run.

UPDATE 1

Two further download locations can be found at:

www.momstav.com/087hg67
perfumy_alice.republika.pl/08h867g5

The dropped binaries are different again [1] [2],  but it is still Locky phoning home to the C2s detailed here.

UPDATE 2

Further download locations are at:

50.28.211.199/hdd0/89o8i76u5y4
galit-law.co.il/32tguynjk
peterdickem.com/87745g
scorpyofilms.com/67j5h5h4
thaihost.biz/bestylethai.com/43t3gh4

Again, the dropped binaries are all different but seem to be Locky [1] [2] [3] [4] [5].

Malware spam: "Scanned image" / "Image data in PDF format has been attached to this email."

This fake document scan leads to malware. It appears to come from within the victim's own domain, but this is a trivial forgery.

Image data in PDF format has been attached to this email.

Attached is a document named in a similar format to 11-03-2016-6440705503.zip which contains a randomly-named malicious script. So far I have seen three versions of this script (VirusTotal results [1] [2] [3]) which according to the Malwr reports [4] [5] [6] download a malicious binary from:

ghayatv.com/system/logs/uy78hn654e.exe

This is Locky ransomware, the same as dropped in this other spam run - that post also contains a list of C2s to block.

That binary has a detection rate of 4/55. According to the Malwr report for the script and this Malwr report for the binary, it phones home to:

31.184.196.75 (Petersburg Internet Network, Russia)

Dear Client!

For the third time we are reminding you about your unpaid debt.

Details on the individual emails vary. Attached is a ZIP file which contains one of a variety of malicious scripts (sample VirusTotal results [1] [2] [3] [4]). According to these Malwr reports [5] [6] [7] these scripts attempt to download a malicious binary from the following locations:

http://hellomississmithqq.com/69.exe?1
http://hellomississmithqq.com/80.exe?1
http://mommycantakeff.com/69.exe?1

74.117.183.252 (WZ Communications, US)
91.243.75.135 (Martin Andrino Ltd, Netherlands)

This Malwr report and this Hybrid Analysis shows communications with:

78.40.108.39 (PS Internet Company LLC, Kazakhstan)
178.162.214.146 (Leaseweb, Germany)

The two executables seem different (VirusTotal results [1] [2]). It looks like it might be dropping both ransomware (Teslacrypt perhaps) and Dridex (banking trojan) alternately.

Malware spam: "Document No 4873206" / Accounts [accounts@victimdomain.tld]

This fake financial email has a malicious attachment:

From:    Accounts [accounts@victimdomain.tld]
Date:    10 March 2016 at 11:45
Subject:    Document No 4873206

Thanks for using electronic billing

Please find your document attached

Regards

Accounts

The email appears to come from within victim's own domain. The number in the subject varies, and is matched by the attachment name (e.g. Document No 4873206.zip). In turn this contains one of several malicious scripts (VirusTotal results [1] [2] [3] [4] [5] [6]). All the Malwr reports [7] [8] [9] [10] [11] [12] all show an attempted download from:

ncrweb.in/system/logs/7t6f65g.exe

Happily this 404s, but it is likely that other scripts will have the same download locations as found here. The payload is the Locky ransomware, and it should drop an executable with a detection rate of 1/56. 

Malware spam: "Attached File" / canon@victimdomain.tld leads to Locky

This spam has a malicious attachment. It appears to come from within the sender's own domain. There is no body text.

From:    canon@victimdomain.tld
Date:    10 March 2016 at 09:02
Subject:    Attached File

In the sample I saw, there was an attachment victimname@victimdomain.tld_07567_273772.zip which contained a randomly-named script with a detection rate of 5/57. Automated analysis [1] [2] shows that this is the Locky ransomware, and it downloads a binary from:

buyfuntees.com/system/logs/7t6f65g.exe

This binary has a detection rate of  just 1/56. Those reports indicate that the malware phones home to:

31.184.196.78 (Petersburg Internet Network Ltd, Russia)
78.40.108.39 (PS Internet Company LLC, Kazakhstan)

There are probably many other download locations and some more C2s as well, I will update this post if I see them.

This additional analysis is from a trusted third party (thank you!)

Malware spam: "Final Notice About Unpaid Bill" / "Important Notice About Created Invoice" / "Important Message About New Invoice"

This fake financial spam comes with a malicious attachment.The sender's name, subject and body text has a variety of text in, including:

Subject:
Fwd: Final Notice About Unpaid Bill
Fw: Important Notice About Created Invoice
Re: Important Message About New Invoice

Body text:
Pls see the bill attached.
review the report attached.
check the invoice attached.

Some more examples can be seen here.

Attached is a randomly-named document, of which I have seen three samples (VirusTotal results [1] [2] [3]). The Malwr report on one of the samples plus these Hybrid Analysis reports [4] [5] [6] shows a download of an encrypted file from:

darrallmacqueen.com/b2.jpg?XhVee=9
darrallmacqueen.com/b2.jpg?XhVee=20
darrallmacqueen.com/b2.jpg?XhVee=16

The dropped files seem pretty random, indeed in all the samples the binaries were different with some generic detections [1] [2] [3] [4]. All of the samples crash in Malwr [5] [6] [7] [8].

It all seems a little odd and if I get more information on what is happening, I will update this post. In the meantime the only mitigating step I can think of is to block traffic to darrallmacqueen.com which should stop the files downloading.

These malicious scripts all have low detection rates [1] [2] [3] [4] [5] [6]. The Malwr reports for those samples [7] [8] [9] [10] [11] [12] show that the scripts download a binary from:

ihsanind.com/system/logs/87jhg44g5
nguoitieudungthongthai.com/system/logs/987i6u5y4t
astralia.ro/08o76g445g [404]

Only two of the download locations work, dropping binaries with a detection rate of 5/55 [1] [2]. Note that there may be other download locations.

The Malwr reports indicate that the malware phones home to:

78.40.108.39 (PS Internet Company LLC, Kazakhstan)
149.154.157.14 (EDIS, Italy)

The payload is the Locky ransomware.

Malware spam: "DOC-Z21193008" / Idris Mohammed [idrismohammed25@gmail.com]

This terse spam has a malicious attachment. There is no body text.

Subject:    DOC-Z21193008

Attached is a file img-DOC-Z21193008.docm which I have seen two versions of (VirusTotal results [1] [2]). Automated analysis [3] [4] [5] [6] shows the macro in these two documents downloading from:
 
gpcarshop.com.br/system/logs/07yhnt7r64.exe
karnavalnye.com/system/logs/07yhnt7r64.exe

There are no doubt several other download locations. This binary has a detection rate of 3/56. The various reports indicate that it phones home to a server at:

64.76.19.251 (Impsat, Argentina)

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

Malware spam: "Compensation - Reference Number #368380" leads to Locky

This fake financial spam comes with a malicious attachment:

From:    Orval Burgess
Date:    8 March 2016 at 11:10
Subject:    Compensation - Reference Number #368380

Dear Customer,

The mistake made will be compensated promptly, please do not worry.
Please take a look at the file attached (scanned document) as it contains all the information.


Sincerely,
Orval Burgess
Account Manager

Attached is a file named in a similar format to SCAN_00_368380.zip which contains TWO malicious scripts named in a format similar to email.864036956.js (VirusTotal results [1] [2] [3] [4]) and automated analysis tools [5] [6] [7] [8] [9] [10] [11] [12] show binary download locations at:

ministerepuissancejesus.com/o097jhg4g5
ozono.org.es/k7j6h5gf

Those same reports indicate the malware attempts to phone home to the following IPs:

89.108.85.163 (Agava Ltd, Russia)
151.236.14.51 (EDIS, Netherlands)
149.154.157.14 (EDIS, Italy)
37.235.53.18 (EDIS, Spain)
192.121.16.196 (EDIS, Sweden)

Those automated reports all indicate that this is the Locky ransomware.

UPDATE

A trusted source also informs me of these additional download locations;

Malware spam: "Samson Floyd agent Fedex" / "FeDex-service"

This fake FedEx spam has a malicious attachment:

From:    FeDex-service
Date:    8 March 2016 at 11:40
Subject:    Samson Floyd agent Fedex

Dear [redacted],
We attempted to deliver your item on March 07th, 2016, 11:40 AM.
The delivery attempt failed because the address was business closed or
nobody could sign for it. To pick up the parcel,please, print the receipt
that is attached to this email and visit Fedex office indicated in the
invoice. If the package is not picked up within 48 hours, it will be returned
to the shipper.

Label: US45928402845
Expected Delivery Date: March 07th, 2016
Class: International Package Service
Service(s): Delivery Confirmation
Status: Notification sent

Thank you for choosing our service

Attached is a RAR archive file in this case named US45928460284.rar containing in turn a malicious script US45928460284.js which is rather curious [pastebin]. This attempts to download an executable from:

www.fotoleonia.it/files/sample.exe

This has a VirusTotal detection rate of 4/54. The Malwr report shows a subsequent download from:

www.claudiocalaprice.com/modules/fedex/pad.exe

This has similar detections to the first binary.  That Malwr report also indicates the binary POSTing data to:

pdf.repack.bike/new_and/state.php

This is hosted on:

151.80.76.200 (Kitdos, US / OVH, France)

I would suggest that the entire 151.80.76.200/29 range is questionable and should be blocked.

None of the automated tools I ran [1] [2] [3] [4] gave any insight as to what the malware does, but it is clearly something malicious.

Attached is a file pm51A.docm which I have seen two versions of (VirusTotal results [1] [2]). According to these Malwr reports [3] [4] and various other sources the macro in the document downloads from:

The dropped binary has changed from earlier and has a detection rate of 2/55, it phones home to the same IP address as seen in this campaign. It appears to be the Dridex banking trojan.

Malware spam: "Emailing: 20121005154449756" / Gary Atkinson [Gary@garrardwindows.co.uk]

This spam does not come from Garrard Windows but is instead a simple forgery with a malicious attachment:

Please find attached document as requested.

Attached is a file 20121005154449756.zip which contains a randomly-named script. I have seen two samples so far (VirusTotal results [1] [2]). The Malwr reports [3] [4] show the script downloads from the following locations:

jatukarm-30.com/9uj8n76b5.exe
stopmeagency.free.fr/9uj8n76b5.exe

The downloaded binary appears to be Dridex and is the same as found in this spam run.

I have only seen a single sample with an attachment named Pay_Advice_Vendor_0000300320_1000_for_03.03.2016.PDF.ZIP which contains a randomly-named malicious script with a detection rate of 3/54.

According to the Malwr report and Hybrid Analysis on this sample, it downloads a malicious binary from:

lhs-mhs.org/9uj8n76b5.exe

This binary has a detection rate of 2/54 and all those reports indicate that it phones home to:

38.64.199.3 (PSINet, Canada)

I recommend that you block traffic to that IP. The Malwr report on the dropped binary is inconclusive, but it looks like the Dridex banking trojan.
