Malware spam: "Agreement form" leads to Locky

This fake financial spam leads to malware:

Subject:     Agreement form
From:     Marlin Gibson
Date:     Wednesday, 7 September 2016, 9:35

Hi there,

Roberta assigned you to make the payment agreement for the new coming employees.

Here is the agreement form. Please finish it urgently.

Best Regards,
Marlin Gibson
Support Manager

The name of the sender will vary. Attached is a ZIP file named with a random hexadecimal sequence, containing a malicious .JS script ending with agreement_form_doc.js and in the sample I saw there was also a duplicate..

308F92BC agreement_form_doc - 1.js
308F92BC agreement_form_doc.js

Automated analysis [1] [2] shows that the scripts [partly deobfuscated example] attempt to download a binary from one of the following locations:

donttouchmybaseline.ws/ecf2k1o
canonsupervideo4k.ws/afeb6
malwinstall.wang/fsdglygf
listofbuyersus.co.in/epzugs

Of those locations, only the first three resolve, as follows:

donttouchmybaseline.ws 216.244.68.195 (Wowrack, US)
canonsupervideo4k.ws   51.255.227.230 (OVH, France / Kitdos)
malwinstall.wang       51.255.227.230 (OVH, France / Kitdos)

The registration details for all those domains are the same:

  Registry Registrant ID:
  Registrant Name: Dudenkov Denis
  Registrant Organization: Eranet International Limited
  Registrant Street: Lenina 18 Lenina 18
  Registrant City: Vladivostok
  Registrant State/Province: RU
  Registrant Postal Code: 690109
  Registrant Country: RU
  Registrant Phone: 85222190860
  Registrant Phone Ext:
  Registrant Fax:
  Registrant Fax Ext:
  Registrant Email: volosovik@inbox.ru
  Registry Admin ID:

These are the same details as found here. We know from that incident that the download locations are actually spread around a bit:

23.95.106.206 (New Wave NetConnect, US)
51.255.227.230 (OVH, France / Kitdos)
107.173.176.4 (Virtual Machine Solutions LLC, US)
192.3.7.198 [hostname: ns2.3arab.net] (Hudson Valley Host, US)
216.244.68.195 (Wowrack, US)
217.13.103.48 (1B Holding ZRT, Hungary)

The following also presumably evil sites are also hosted on those IPs:

bookinghotworld.ws
clubofmalw.ws
darkestzone2.wang
donttouchmybaseline.ws
canonsupervideo4k.ws
malwinstall.wang
wangmewang.name
tradesmartcoin.xyz
virmalw.name

Currently I am unable to work out the C2 locations for the malware, which is probably Locky ransomware. In the meantime, I recommend you block:

51.255.227.228/30
23.95.106.206
107.173.176.4
192.3.7.198
216.244.68.195

Malware spam: "We are sending you the credit card receipt from yesterday. Please match the card number and amount."

This fake financial spam has a malicious attachment:

From:    Tamika Good
Date:    5 September 2016 at 08:43
Subject:    Credit card receipt

Dear [redacted],

We are sending you the credit card receipt from yesterday. Please match the card number and amount.


Sincerely yours,
Tamika Good
Account manager

The spam will appear to come from different senders. Attached is a ZIP file with a random hexadecimal name, in turn containing a malicious .js script starting with the string credit_card_receipt_

A Malwr analysis of three samples [1] [2] [3] shows each one downloading a component from:

canonsupervideo4k.ws/1bcpr7xx

This appears to be multihomed on the following IP addresses:

23.95.106.206 (New Wave NetConnect, US)
107.173.176.4 (Virtual Machine Solutions LLC, US)
192.3.7.198 [hostname: ns2.3arab.net] (Hudson Valley Host, US)
217.13.103.48 (1B Holding ZRT, Hungary)

Of interest, the WHOIS details have been seen before in relation to Locky. They are probably fake:

  Registrant Name: Dudenkov Denis
  Registrant Organization: Eranet International Limited
  Registrant Street: Lenina 18 Lenina 18
  Registrant City: Vladivostok
  Registrant State/Province: RU
  Registrant Postal Code: 690109
  Registrant Country: RU
  Registrant Phone: 85222190860
  Registrant Phone Ext:
  Registrant Fax:
  Registrant Fax Ext:
  Registrant Email: volosovik@inbox.ru

Those reports indicate that a malicious DLL is dropped with a detection rate of 9/57.  These Hybrid Analysis reports [4] [5] [6] show the malware phoning home to:

91.211.119.71/data/info.php [hostname: data.ru.com] (Zharkov Mukola Mukolayovuch aka 0x2a, Ukraine)

Malware spam: "old office facilities" leads to Locky

This spam has a malicious attachment:

Subject:     old office facilities
From:     Kimberly Snow (Snow.741@niqueladosbestreu.com)
Date:     Friday, 2 September 2016, 8:55

Hi Corina,

Attached is the list of old office facilities that need to be replaced. Please copy the list into the purchase order form.


Best wishes,
Kimberly Snow

The name of the sender will vary. Attached is a ZIP file with a random hexadecimal number, containing a malicious .js script beginning with office_facilities_ plus another random hexadecimal number.

Analysis is pending, but this Malwr report indicates attempted communications to:

malwinstall.wang
sopranolady7.wang

..both apparently hosted on 66.85.27.250 (Crowncloud, US). Those domain names are consistent with this being Locky ransomware.

UPDATE 1

According to this Malwr report it drops a DLL with a detection rate of 10/58. Also those mysterious .wang domains appear to be multihomed on the following IPs:

Malware spam: "orderconfirmation@esab.co.uk" / "Order Confirmation-7069-2714739-20160815-292650"

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

Attached is a file with a name similar to Order_Confirmation-7069-2714739-20160815-292650.docm which contains a malicious macro. There are various versions, which according to my source (thank you) download a component from one of the following locations:

The email appears to come from within the victim's own domain (but this is just a simple forgery). Attached is a ZIP file with a name similar to 201608120908.zip which contains a malicious .WSF script with a name similar to doc(171)-12082016.wsf

This Hybrid Analysis shows the script downloading a file from www.hi-segno.com/02bjJBHDs?WUubFbrItd=ratyCr (and also the same location on bonmoment.web.fc2.com and www.homesplus.nf.net) but a trusted source tells me that the following download locations appear in different scripts:

The sender name and numbers in the subject vary, and it appears to come from within the sender's own domain (this is just a simple forgery). Attached is a malicious Word document with a name similar to New Doc 666-9.docm. A Hybrid Analysis of one sample shows a download location of fcm-makler.de/4GBrdf6 and my sources (thank you) tell me that there are many others, giving the following list:

Malware spam: "Please sign the receipt attached for the arrival of new office facilities." leads to Locky

Yet another Locky campaign today..

From:    Erica Hutchinson
Date:    4 August 2016 at 12:34
Subject:    please sign

Dear [redacted]

Please sign the receipt attached for the arrival of new office facilities.


Best regards,
Erica Hutchinson

This drops Locky ransomware through a malicious attachment. It appears to be largely the same as found in this earlier spam run.

Malware spam: "Emailing: Sheet / Document / Invoice" with a .docm leads to Locky

This malware-laden spam comes with a variety of subjects, for example:

Emailing: Invoice (79).xls
Emailing: Sheet (189).doc
Emailing: Sheet (3352).tiff
Emailing: Document (79).doc
Emailing: Invoice (443).doc
Emailing: Sheet (679).xls
Emailing: Document (291).pdf

There is no body text. Attached is a .docm file with the same prefix as the subject (e.g. Document (291).pdf.docm) which contains a macro that downloads a malicious component from one of the following locations:

abi64.com/h78r3gfe

Malware spam: "Business card" / "I have attached the new business card design." leads to Locky

This spam email has a malicious attachment:

From:    Glenna Johnson
Date:    4 August 2016 at 10:18
Subject:    Business card

Hello [redacted],

I have attached the new business card design.
Please let me know if you need a change


King regards,
Glenna Johnson
c75b53fd1ea488ebe8eaf068fd5c9dd13f1848f4d3a7

Sender names and that long hexadecimal number with vary. Attached is a randomly-named ZIP file containing a malicious .js script beginning with "business card" [example]. The payload appears to be Locky ransomware.

This Hybrid Analysis of the script gives plenty of detail as to what is going on. My trusted sources tell me that the list of download locations is quite short:

escapegasmech.com/048220y5
goldjinoz.com/0a3tg
platimunjinoz.ws/13fo8lnl
regeneratewert.ws/1qvvu9lu
traveltotre.in/2c4ykij7

This drops a binary with a detection rate of 8/54. The earlier Hybrid Analysis report shows it phoning home to:

31.41.46.29/php/upload.php (Relink Ltd, Russia) [hostname: ip.cishost.ru]
185.129.148.19/php/upload.php (MWTV, Latvia)

All of those network blocks have a pretty poor reputation and I recommend that you block their entire ranges.

Malware spam: "Confirmation letter" leads to Locky

Another spam run leading to Locky ransomware..

From:    Mavis Howe [Howe.4267@croestate.com]
Date:    3 August 2016 at 13:32
Subject:    Confirmation letter

Hi [redacted],

I attached the employment confirmation letter I prepared.
Please check it before you send it out.

Best regards

Mavis Howe

The name of the sender varies from email to email. The malicious attachment and payload seem very close to the one described here.

Malware spam: "As you directed, I send the attachment containing the data about the new invoices"

Another day, another Locky ransomware run:

From:    Marian Mcgowan
Date:    3 August 2016 at 11:15
Subject:    Fw: New invoices

As you directed, I send the attachment containing the data about the new invoices

Attached is a randomly-named ZIP file which contains a highly obfuscated .js script  which according to this Malwr analysis downloads a binary from..

blog-aida.cba.pl/2zensi7t

..when decrypted it creates a binary with a detection rate of 4/54. That same Malwr analysis shows it phoning home to:

93.170.104.20/php/upload.php (Breezle LLC, Netherlands) [hostname: pundik.rus.1vm.in]

This IP was seen last night and it seems that there is a concurrent Locky spam run phoning home to:

185.129.148.19/php/upload.php (MWTV, Latvia)
89.108.127.160/php/upload.php (Agava, Russia) [hostname: srv1129.commingserv.com]

Both those IPs are in known bad blocks.

Malware spam: "Please review the attached corrected annual report." / "Corrected report"

This spam comes with a malicious attachment:

Date:     Monday, 1 August 2016, 13:37

Dear webmaster,
