Fake eFax spam uses hacked Sharepoint to spread malware

This fake fax leads to a malicious ZIP file:

Subject:    eFax message from "61 2 97855412" - 2 page(s)

The link in the email goes to a hacked Sharepoint account, in this case:

https://supremeselfstorage-my.sharepoint.com/personal/andrew_supremeselfstorage_com_au/_layouts/15/guestaccess.aspx?guestaccesstoken=GTQPc%2brKLAsKHba4nXtvl0hXrBsUmCUxoYGuu9msk0U%3d&docid=0c4b96dfd3319496a8feb1a56d88de679&rev=1

It seems to belong to a legitimate company, but maybe one that has suffered an Office 365 compromise.

The ZIP file it leads to is named Fax_11292016.zip (there may be other versions) containing two identical scripts named

Fax_11292016_page1.js
Fax_11292016_page2.js

that look like this. Hybrid Analysis of the script indicates this is Nymaim, downloading a component from:

siliguribarassociation.org/images/staffs/documetns.png

A malicious EXE is dropped with an MD5 of bdf952b2388bf429097b771746395a4c and a detection rate of 9/56. The malware then phones home to:

stengeling.com/20aml/index.php

The domain stengeling.com appears to have been created for this malware and has anonymous registration details. It is apparently multihomed on the following IPs:

4.77.129.110
18.17.224.92
31.209.107.100
37.15.90.12

115.249.171.24
119.71.196.177

176.114.21.171
184.131.179.44
207.77.174.212

Each of those IPs appears to be a hacked legitimate host, with a high turnover of IPs. Those IPs appear to be associated with the following domains that may be worth blocking:

butestsis.com
sievecnda.com
specsotch.com
crileliste.com

Although the numbers and some other details change in the spam messages, in all cases the download location has been from a legitimate but hacked site at:

breedandco.com/fileshare/FAX-1400166434-707348006719-154.zip

The ZIP file has a detection rate of 6/55 and it contains a malicious exeuctable named FAX-1400166434-707348006719-154.scr which has a detection rate of 4/55. Automated analysis [1] [2] [3] shows a characterstic callback pattern that indicates Upatre (which always leads to the Dyre banking trojan):

93.185.4.90:12325/ETK7/<MACHINE_NAME>/0/51-SP3/0/GKBIMBFDBEEE
93.185.4.90:12325/ETK7/<MACHINE_NAME>/41/5/1/GKBIMBFDBEEE

This IP is allocated to C2NET in the Czech Republic. The malware also attempts to enumerate the IP address of the target by accessing checkip.dyndns.org which is a legitimate service. It is worth looking for traffic to that domain because it is a good indicator of compromise.

The malware reaches out to some other malicious IPs (mostly parts of a botnet):

93.185.4.90 (C2NET, Czech Republic)
62.204.250.26 (TTNET, Czech Republic)
76.84.81.120 (Time Warner Cable, US)
159.224.194.188 (Content Delivery Network Ltd, Ukraine)
178.222.250.35 (Telekom Srbija, Serbia)
181.189.152.131 (Navega.com, Guatemala)
194.28.190.84 (AgaNet Agata Goleniewska, Poland)
194.28.191.213 (AgaNet Agata Goleniewska, Poland)
199.255.132.202 (Computer Sales & Services Inc., US)
208.123.135.106 (Secom Inc, US)

Among other things, the malware drops a file XGwdKLWhYBDqWBb.exe [VT 10/55] and vastuvut.exe [VT 6/55].

Predictably, the link leads to a malicious download (this time at storage-ec2-24.sharefile.com) named Fax_00491175.zip and containing in turn a malicious executable Fax_00491175.scr.

This executable has a detection rate of 5/57. Automated analysis tools [1] [2] [3] shows that it downloads a further component from:

http://employmentrisk.com/images/1405uk77.exe

In turn, this has a detection rate of 4/57 and the Hybrid Analysis report indicates that it tries to communicate with 194.28.190.183 (AgaNet Agata Goleniewska, Poland).

"INCOMING FAX REPORT" spam, let's party like it's 1999

This is (of course) utter bollocks, and the link in the email downloads a ZIP file document_8731_pdf.zip which in turn contains a malicious executable document_8731_pdf.exe which has a VirusTotal detection rate of 4/54. According to the Malwr report it makes these following HTTP requests:

http://159593.webhosting58.1blu.de/mandoc/narutus1.pmg

It also drops a file EXE1.EXE onto the target system which has a detection rate of 7/55. You can see the Malwr report for that here.

The telephone number seems to very but is always in the 0208616xxxx format.

The link in the email goes to some random hacked WordPress site or other with a URL with a format similar to the following:

http://tadarok.com/wp-content/themes/deadline/mess.html
http://107.170.219.47/wp-content/themes/inove/mess.html
http://dollfacebeauty.com.au/wp-content/themes/landscape/mess.html

Then (if your user agent and referrer are correct) it goes to a fake eFax page at http://206.253.165.76:8080/ord/ef.html which does look pretty convincing. (Incidentally if the UA or referrer are not right you seem to get dumped on a pills site of naturaldietpills4u.com).

The download link goes to http://206.253.165.76:8080/ord/FAX_20141008_1412786088_26.zip which is a ZIP file containing a malicious executable FAX_20141008_1412786088_26.exe which has a VirusTotal detection rate of 4/54.

The Malwr report is interesting because it contains many references to bacstel-ip which is the name of an online payment system used by UK businesses. The malware also contains the string

runas /profile /env /user:mydomain\admin "mmc %windir%\system32\dsa.msc

 If you are a sysadmin then you might recognise this as being the "Active Directory Users and Computers" admin tool. So, are the bad guys probing for sysadmins?

The malware connects to the following URLs:

http://212.59.117.207/yqqwe9mN5yoZJwBcwDqo0kTckoyNuHmw3cXoyRRFa/kaT1aBHyLi9Ne5TcaVNg3ik0NkDZ4ZqwwP/J9s1iNPmFwLiTgJuwky

I recommend blocking 107.170.19.156 (Digital Ocean, US), 212.59.117.207 (IO-Hosts Ltd, Russia) and 206.253.165.76 (Arachnitec, US)

In this case the link in the email goes to verzaoficial.com/css/fax_390392029_072514.exe which downloads a file with a VirusTotal detection rate of just 1/45. Automated analysis [pdf] is fairly inconclusive as to what it does.

Attached to the message is a file FAX_10302013_1013.zip which in turn contains FAX_10302013_1013.exe (although the date is encoded into the filename so your version may be different) which has an icon that makes it look like a PDF file.

This has a very low detection rate at VirusTotal of just 1/46. Automated analysis tools [1] [2] [3] show an attempted connection to a domain bulkbacklinks.com on 69.26.171.187. This is part of the same compromised Xeex address range as seen here and here.

Xeex have not responded to notifications of a problem (apart from an AutoNACK). I recommend that you treat the entire 69.26.171.176/28 range as being malicious and you should block according to this list.

The link in the email goes through a legitimate hacked site and then runs one of the following three scripts:
[donotclick]die-web-familie.homepage.t-online.de/quasar/monte.js
[donotclick]dim-kalogeras-ka-lar.schools.ac.cy/initials/casanovas.js
[donotclick]ade-data.com/exuded/midyear.js

These then lead to a malware payload at [donotclick]rockims.com/topic/seconds-exist-foot.php which is a hijacked GoDaddy domain hosted on 192.81.133.143 (Linode, US) along with quite a few other hijacked domains (listed in italics below).

One leads to a malicious landing page at [donotclick]173.255.223.77/links/assure_numb_engineers.php hosted by Linode in the US.

The other one is a bit odder, referring to a file called chase.swf on a hacked site. VT analysis shows just 1/44 which is not good. That looks a bit like this:

{html}
{body}
{object width='255' height='57'}
 {param name='movie' value='infected.swf'} {/param}
 {param name='allowScriptAccess' value='sameDomain'} {/param}
 {embed width='255' height='57'
  src='hxxp:||[redacted].com/chase.swf' name='BridgeMovie'
  allowScriptAccess='sameDomain' type='application/x-shockwave-flash' }
 {/embed}
{/object}
{/body}
{/html}

Beats me what it is. Probably nothing good though...
