Malware sites to block 2/3/14

These domains and IPs are all connected with this gang, some of it appears to be involved in malware distribution, fraud or other illegal activities. I recommend that you block these IPs and domains.

Note that some of the IPs listed below are compromised nameservers (marked [ns]) which look like they are insufficiently well locked down. There is a plain list of IPs at the end for copy-and-pasting.

From the job description, this appears to be some sort of parcel mule scam or other criminal activity. This video explains how a parcel reshipping scam works:

seekcousa.com is regsitered with Chinese registrar BIZCN, and the WHOIS details are fake:
Registrant Name: Ernest Dubose
Registrant Organization: Ernest D. Dubose
Registrant Street: 129 Oakridge Lane
Registrant City: Irving
Registrant State/Province: TX
Registrant Postal Code: 75038
Registrant Country: us
Registrant Phone: +1.4699959821
Registrant Phone Ext:
Registrant Fax: +1.4699959821
Registrant Fax Ext:
Registrant Email: info@seekcousa.com
Registry Admin ID:


seekconz.com is also registered with BIZCN, but with different fake details:
Registrant Name: Nickolas Gordon
Registrant Organization: Nickolas R. Gordon
Registrant Street: 4930 Clarence Court
Registrant City: Ontario
Registrant State/Province: CA
Registrant Postal Code: 91762
Registrant Country: us
Registrant Phone: 909-988-6071
Registrant Phone Ext:
Registrant Fax: 909-988-6333
Registrant Fax Ext:
Registrant Email: info@seekconz.com

There is no website associated with either of these domains, but there are mail records of mx.seekconz.com and mx.seekcousa.com pointing to 93.190.137.5 (Worldstream, Netherlands). Nameservers involved in the fraud are ns1.friscolakesgc.net hosted on the same IP and ns2.friscolakesgc.net hosted on 32.21.129.43 (AT&T, US).

We can dig a little deeper on those nameserver records, they have fake WHOIS details as well:
Registrant Name: ROSEMARY CARPIO
Registrant Organization:
Registrant Street: 701 Collins Ave, Apt 4B
Registrant City: MIAMI BEACH
Registrant State/Province: FL
Registrant Postal Code: 33139-6203
Registrant Country: US
Registrant Phone: +1.7868777722
Registrant Phone Ext.:
Registrant Fax:
Registrant Fax Ext.:
Registrant Email: haveacupoft@gmx.us
Registry Admin ID:

These fake details also appear on a domain airnavrace.net which is used as a namserver domain for the following domains and uses the following IPs:
quarter.su
147.249.171.10 (IDD Information Services, US)
42.96.195.183 (Alibaba, China)

.su domains are usually bad news, and I suspect that quarter.su is up to no good. The WHOIS details for this domain don't give much detail..

domain: QUARTER.SU
nserver: ns1.aim-darts.net.
nserver: ns1.airnavrace.net.
state: REGISTERED, DELEGATED
person: Private Person
e-mail: bartels@xrbox.com
registrar: R01-REG-FID
created: 2013.12.09
paid-till: 2014.12.09
free-date: 2015.01.11
source: TCI

That domain is multihomed on a bunch of IPs:

176.53.125.6 (Radore Veri Merkezi Hizmetleri, Turkey)
37.255.241.29 (TCE, Iran)
108.81.248.139 (William Allard / AT&T, US)
65.27.155.176 (Time Warner Cable, US)
203.235.181.138 (KRNIC, Korea)
95.57.118.56 (Dmitry Davydenko , Kazakhstan)
186.214.212.64 (Global Village Telecom, Brazil)
89.39.83.177 (C&A Connect SRL, Romania)

This, it turns out is the tip of a very large iceberg of malicious domains and IPs which I will cover in the next post.

In the samples that I have seen the link in the email goes to either [donotclick]exivenca.com/support.php or [donotclick]vicorpseguridad.com/support.php both of which are currently down but were both legitimate sites hosted on 213.152.26.150 (Neo Telecoms, France). The fact that these sites are down could be because the host is dealing with the problem, however I would expect to see this same email template being used again in the future, so take care..

On the trail of 3NT Solutions LLP

NOTE: An updated list of IPs can be found here (October 2017)

Yesterday I blogged about a company called 3NT Solutions LLP apparently based in the UK and expressed my reservations about them as a business. They operate quite a large range of IP addresses, but a quick Google search shows pitifully little about this company.

Let's start our investigation by looking them up at Companies House. That gives some basic details:

3NT SOLUTIONS LLP
SUITE 4084
10 GREAT RUSSELL STREET
LONDON
ENGLAND
WC1B 3BQ
Company No. OC363382

LLPs are a relatively new type of company in the UK which allows a firm to be registered with the minimum of details, but there are reports that LLP structures are being widely abused. We'll have a look at the ownership in a moment, but first let's check out this grand-sounding office in Central London..

View Larger Map

It is, in fact, the Bloomsbury branch of Mail Boxes Etc and "suite" is simply a euphemism for "mail box".. in other words, this is a mail drop address that most likely forwards any mail to another address, a trick that conceals the full owners of the company.

OK, so that address is a bust. But the WHOIS records for their IP blocks, and their previous address registered at Companies House is something different:

DALTON HOUSE
60 WINDSOR AVENUE
LONDON
SW19 2RR

We can trundle over to that on Google StreetView too..

View Larger Map

Dalton House is basically the same thing as the MBE address, it offers a brass plaque somewhere and a mail forwarding service. So no real clues as to ownership here either.

A trip back to Companies House to find their Company Register information [rtf] reveals very little, except two related companies in Belize.

LLP DESIGNATED MEMBER:	DARL IMPEX LTD
Appointed:	01/04/2011
Nationality:	NATIONALITY UNKNOWN
No. of Appointments:	1
Address:	35 NEW ROAD
	BELIZE
	BELIZE
	NA

LLP DESIGNATED MEMBER:	LEGRANT TRADING LTD.
Appointed:	19/03/2013
Nationality:	NATIONALITY UNKNOWN
No. of Appointments:	1
Address:	BLAKE BUILDING SUITE 102, GROUND FLOOR, BLAKE BUIL
	CORNER EYRE&HUTSON STREETS
	BELIZE CITY
	BELIZE
	NA

Belize is a pretty much a haven for offshore companies, so it is quite likely that these two Belize companies are owned by someone in a different country again.

The domain registration for 3nt.com doesn't really give any more information, and oddly enough their website is down (so how do they expect to attract business?). But if we do a WHOIS lookup on one of their IP ranges then it becomes much more clear.

Alright, let's cut a long story short because we know who this is.. it's Serbian web host inferno.name who have featured on this blog several times before all the way back to 2011. Similar records exist on all of 3NT's ranges, linking them firmly with inferno.name.

Not it's not a particular surprise to see that inferno.name is trading under a different name, as the scummy sites they host pretty much ruined their reputation. And yeah, this blog helped with that.

I had a look into some of 3NT's IP ranges and you can tell instantly from these samples [csv] that they are pretty low-grade spammy sites. What you can't tell from that list are the command and control servers that they run, and of course they also host malware.

The following IP range are allocated to 3NT Solutions LLP. I recommend that you block them.
5.45.64.0/21
5.45.72.0/22
5.45.76.0/22
5.61.32.0/20
37.1.192.0/21
37.1.200.0/21
37.1.208.0/21
37.1.216.0/21
37.252.2.0/24
37.252.12.0/24
130.0.232.0/21

In addition, these other (smaller) ranges are allocated to inferno.name and v3servers.net who are the same outfit. I also recommend that you block these:
 46.21.147.128/25
46.21.148.128/25
46.22.211.0/25
80.79.124.128/26
92.48.122.0/28
92.48.122.16/28
92.48.122.32/28
92.48.122.48/28
94.100.17.128/26
95.168.165.0/24

Something evil on 74.50.122.8, 5.61.36.231 and 94.185.85.131

Thanks to @Techhelplistcom for the heads up on this little mystery..

It all starts with a spam evil (described here)..

The link goes to a URLquery report that seems pretty inconclusive,  mentioning a URL of [donotclick]overcomingthefearofbeingfabulous.com/xjvnsqk/fbktojkxbxp.php [an apparently poorly secured server at 74.50.122.8, Total Internet Solutions Pvt. Ltd in India] that just does a redirect to a spammy diet pill site at thefxs.com [94.177.128.10, Linkzone Media Romania] if you have a Windows User Agent set.

As Techhelplist says, set the UA to an Android one and you get a very different result. In this case you get bounced to a site hosted on 5.61.36.231 (3NT Solutions / Inferno.name)

[donotclick]mobile.downloadadobecentral.ru/FLVupdate2.php from where it attempts to download a file FlashUpdate.apk

3NT Solutions / inferno.name is a known bad actor and you should block all their IPs on sight, in this case they have a netblock 5.61.32.0/20 which I strongly recommend that you route to the bitbucket.

FlashUpdate.apk has a VirusTotal detection rate of 22/47, but most Android users are probably not running anti-virus software. The Andrubis analysis of that .apk shows a network connection to 94.185.85.131 (Netrouting Telecom, Sweden) plus (oddly) some pages loaded from ticketmaster.com.

It just goes to show that what you think might be harmless spam can actually be something very, very different if you access it on a mobile device.

Recommended blocklist:
5.61.32.0/20
94.177.128.10
74.50.122.8
94.185.85.131
