Malware spam: "Good morning" résumé spam drops Cerber ransomware and makes a statement

This fake résumé spam leads to malware:

From:    Dora Bain
Date:    7 June 2016 at 03:37
Subject:    Good morning

What's Up?
I visited your website today..
I'm currently looking for work either full time or as a intern to get experience in the field.
Please look over my CV and let me know what you think.

With gratitude,

--
Dora Bain
In the sample I saw, the attached file was named Dora-Resume.doc and had a VirusTotal detection rate of 11/56. The Malwr report and Hybrid Analysis show that a script executes that tries to make a political statement along the way..


This downloads a file from 80.82.64.198/subid1.exe which is then saved as %APPDATA%\us_drones_kills_civilians.exe  which VirusTotal gives a detection rate of 20/56 and seems to give an overall diagnosis as being Cerber ransomware.

The IP address of 80.82.64.198 is allocated to an apparent Seychelles shell company called Quasi Networks Ltd (which is probably Russian). There seems to be little if anything of value in 80.82.64.0/24 which could be a good candidate to block. Incidentally, the IP hosts best-booters.com which is likely to be a DDOS-for-hire site.

According to the VT report the malware scans for a response on port 6892 on the IP addresses 85.93.0.0 through to 85.93.63.255. However, this Hybrid Analysis indicates that the only server to respond is on 85.93.0.124 (GuardoMicro SRL, Romania) which is part of the notoriously bad 85.93.0.0/24 which is a good thing to block.

That report also shows traffic to ipinfo.io which is a legitimate "what is my IP" service. While not malicious in its own right, it does make a potentially good indicator of compromise.

Recommended blocklist:
80.82.64.0/24
85.93.0.0/24

Malware spam: "Neue Abrechnung Nr. 746441" / support@sipcall.de

This German-language spam has a malicious attachment:

From:    support@sipcall.de

Subject:    Neue Abrechnung Nr. 746441


Guten Tag

Reference numbers vary. Attached is a randomly-named Word document (e.g. INV842038-746441.docm). The sample I submitted to Malwr showed it downloading a binary from:

There are probably other locations too.

An executable is dropped with a detection rate of 3/56. The Hybrid Analysis and DeepViz report both indicate different phone-home locations:

193.9.28.13 (FLP Kochenov Aleksej Vladislavovich / uadomen.com, Ukraine)
5.152.199.70 (Redstation, UK)


Private sources also indicate C2s at:

212.109.219.31 (JSC Server, Russia)
107.181.187.12 (Total Server Solutions, US)


The payload is Locky ransomware.

Malware spam: "Following the phone conversation with the accounting department represantatives I'm sending you the invoices."

These fake financial spams come from different companies, all with a malicious attachment.

From:    Frank.ClaraZO@pr-real.com

Subject:    The invoices from INCHCAPE PLC


Hello,

Attached is a ZIP file with a name similar to Invoice 5044-032841.zip which in turn contains a malicious script named in a similar manner to invoice(677454).js which typically has a detection rate of 3/56. Hybrid Analysis of that sample shows the script creating a PFX (personal certificate) file which is then transformed into a PIF (executable) file using the certutil.exe application.

This PIF file itself has a detection rate of 6/56 but automated analysis [1] [2] [3] is inconclusive. The behaviour is somewhat consistent with the Dridex banking trojan but may possibly be Locky ransomware.

In the two samples I have seen, there are attachments named Security Report.zip and Security Notification.zip which in turn contain a Word document with a name such as Security Report ID(11701573).doc

The two documents that I have seen have detection rates of about 3/56 [1] [2] but according to these automated analyses [3] [4] [5] [6] it seems that the infection doesn't work properly, failing to find a created file harakiri.exe. This Malwr report shows a dropped file named harakiri.pfx which isn't an executable, my guess is that this is an encrypted file that hasn't decrypted properly.

UPDATE

According to a third party analysis, this apparently drops Dridex which phones home to:

210.245.92.63 (FPT Telecom Company, Vietnam)
162.251.84.219 (PDR Solutions, US)

Malware spam: "DocuCentre-IV" / "Scan Data"

This fake document scan appears to come from within the victim's own domain (but this is just a simple forgery) and has a malicious attachment:

Typical VirusTotal detection rates are 6/56 [1] [2] [3] [4] [5] [6]. Various automated analyses of these documents [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] show a binary being downloaded from the following locations:

195.169.147.26 (Culturegrid.nl, Netherlands)
70.164.127.132 (Southland Technology, US)

There are probably many other download locations. This dropped file has a detection rate of 6/56. The DeepViz report and Hybrid Analysis between then identify what is likely to be Dridex, phoning home to the following servers:

Right at the moment this is just a copy of the Windows Calculator and is harmless, but the payload could be switched later to something more malicious, probably Locky ransomware or the Dridex banking trojan.

Attached is a file New Order P201628037.docx which I have seen a single variant of, with a VirusTotal detection rate of 8/58. The Malwr report is inconclusive, but does appear to to show an OLE embedded object within the Word document. There are some interesting strings near the beginning of the object..

Crypted.exe
C:\Users\user\Desktop\Crypted.exe
C:\Users\user\AppData\Local\Temp\Crypted.exe


So, this looks like ransomware. Some inexpert fiddling with the contents of the OLE file yields an executable, and automated reports [1] [2] [3] show network traffic to the domain marchborn.no-ip.biz hosted on:

105.112.39.114 (Airtel, Nigeria)

I strongly recommend that you block traffic to that IP. In fact, the entire very large 105.112.0.0/12 is very sparsely populated and contains a small handful of legitimate Nigerian domains plus a load of Dynamic DNS domains (I've recommended blocking those before) so you might want to consider blocking those too.

Sender names, contact number and attachment names vary, but I have seen just a single variant of the attachment with a VirusTotal detection rate of 1/55. The Malwr report for this sample sees a download from:

bakery.woodwardcounseling.com/michigan/map.php

This download location is almost certainly completely malicious, and is hosted at:

217.12.199.94 (ITL, Ukraine)

This dropped file has a detection rate of 3/56. That VirusTotal and this Malwr report indicate network traffic to:

38.64.199.33 (PSINet, Canada)

Please open and print this attachment and cut out the waybill images. They must be attached to your parcels before the driver arrives.

Thank you for booking with Interparcel.
Attached is a randomly-named document that matches the reference in the email (e.g. Shipping Labels (620486055838).doc) of which I have seen two variants (VirusTotal results [1] [2]). These two Malwr reports [3] [4] show Dridex-like download locations at:

gooddrink.com.tr/wp-content/plugins/hello123/56h4g3b5yh.exe
ziguinchor.caravanedesdixmots.com/wp-content/plugins/hello123/56h4g3b5yh.exe


The detection rate for the binary is 5/57. This DeepViz report on the binary shows network connections to:

195.169.147.26 (Culturegrid.nl, Netherlands)
64.76.19.251 (Level 3, US / Impsat, Argentina)
91.236.4.234 (FHU Climax Rafal Kraj, Poland)
188.40.224.78 (Hetzner / NoTaG Community, Germany)


As mentioned before, these characteristics look like the Dridex banking trojan.

Recommended blocklist:
195.169.147.26

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.

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

This terse spam has a malicious attachment. There is no body text.
From:    Idris Mohammed [idrismohammed25@gmail.com]
Date:    9 March 2016 at 09:55
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.

UPDATE

A contact sent some more download locations (thank you!)

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.

I received only two samples (VT [1] [2]) of which only one worked in Malwr (this is the other). However, third-party analysis (thank you) shows download locations at:

Each location has a different binary (VT [1] [2] [3] [4] [5] [6]) which between them phone home to the following IPs:

In the only sample I have seen before, there is an attached file named archive-0910001923884.docm which has a VirusTotal detection rate of 3/52. Analysis of this document is pending, but it is likely to drop either the Dridex banking trojan or Locky ransomware.

UPDATE 1

The Hybrid Analysis of the document plus the VirusTotal scan of the dropped EXE look like Dridex. The download location for that document was:
