"K J Watking & Co" fake Remittance Advice spam

This fake remittance advice spam has been hammering my inbox this morning. It uses randomly generated sender names but has a consistent fake company name of K J Watking & Co which is very close to a legitimate firm K J Watkin & Co who have nothing to do with this.

The spam comes with an Excel spreadsheet which contains a malicious macro.

Some sample spams are as follows:

The Excel attachments have random names such as BAC_0577719P.xls or BAC_581969Q.xls. So far I have seen two versions of these, neither of which are detected as malicious by any vendors [1] [2].

Each spreadsheet contains a different but similar malicious macro [1] [2] [pastebin] which then download a binary from the following locations:

http://79.137.227.123:8080/stat/lld.php
http://124.217.199.218:8080/stat/lld.php


This file is downloaded as test.exe and is then moved to %TEMP%\EWSUVRXTBUU.exe. It has a VirusTotal detection rate of just 2/52. According to the Malwr report this then drops a DLL with another low detection rate which is identified as Dridex. The ThreatExpert report [pdf] indicates that the malware attempts to communicate with the following IPs:

194.146.136.1 (PE "Filipets Igor Victorovych", Ukraine)
84.92.26.50
(PlusNet, UK)

Recommended blocklist:
194.146.136.1
84.92.26.50

79.137.227.123
124.217.199.218

UPDATE 2014-12-10:

Another spam run is in progress, with a slightly different payload. Again, there are two different XLS files both of which are undetected [1] [2] by AV vendors and containing one of two macros [1] [2] [pastebin] which download from the following locations:

http://41.0.5.138:8080/stat/lld.php
http://217.174.240.46:8080/stat/lld.php

The file is downloaded as test.exe and is saved as %TEMP%\LNUDTUFLKOJ.exe and is the same payload as found in this attack.

How can I know if I have this trojan in my system, and do you know any way to remove it.

Cheers

Hi guys,

I opened the attachment (I know I shouldn't have but I double-clicked out of habit).

What does this mean? I'm guessing they now have access to my PC.

Any remediation advice?

Cheers,
Olie

Surey this can only load if you have Macros enabled in Excel? If you don't then I can't see how it can run.

An instructive post. People to really know who they want to reach and why or else, they'll have no way to know what they're trying to achieve. People need to hear this and have it drilled in their brains..
Thanks for sharing this great article.
