Updated 3NT Solutions LLP / inferno.name / V3Servers.net IP ranges

 

[For the February 2021 version of this list, click here]

When I was investigating IOCs for the recent outbreak of BadRabbit ransomware I discovered that it downloaded from a domain 1dnscontrol.com hosted on 5.61.37.209. This IP belongs to a company called 3NT Solutions LLP that I have blogged about before.

It had been three-and-a-half years since I looked at their IP address ranges so I thought I would give them a refresh. My personal recommendation is that you block all of these, I have never seen anything of worth on any 3NT range. Note that inferno.name and V3Servers.net are the same outfit and I have included those too. If you know of any other ranges, please consider leaving a comment.

5.45.64.0/19
5.61.32.0/19
37.1.192.0/19
37.252.0.0/20
46.22.211.0/25

Malware spam: "Order acknowledgement for BEPO/N1/380006006(2)"

A change to the usual Necurs rubbish, this fake order has a malformed .z archive file which contains a malicious executable with an icon to make it look like an Office document.

Attached is a file Purchase order comfirmation.doc.z which contains a malicious executable Purchase order comfirmation.exe which currently has a detection rate of 12/66. It looks like the archive type does not actually match the extension..


If the intended target hides file extensions then it is easy to see how they could be fooled..

Incidentally, VirusTotal shows this information about the file:


Copyright: (c)1998 by RicoSoft
Product: System Investigation
Description: System Investigation for NT/9x
Original Name: SysInv2.exe
Internal Name: SysInv2
File Version:2.3.1.37
Comments: Freeware / Careware from RicoSoft

Obviously that's fake, but a bit of Googling around shows SysInv2.exe being used in other similar attacks.

The Hybrid Analysis for is a little interesting (seemingly identifying it as Loki Bot), showing the malware phoning home to:

jerry.eft-dongle.ir/njet/five/fre.php   (188.165.162.201 / Mizban Web Paytakht Co. Ltd., Iran)

Actually, the IP is leaded from OVH and claims to belong to dedicatedland.com in Birmingham, UK:

org-name:       Mizban Web Paytakht Mizban Web Paytakht
org-type:       OTHER

last-modified:  2015-01-22T22:12:03Z
source:         RIPE


The small 188.165.162.200/29 range is marked as "failover IPs".  The WHOIS for dedicatedland.com comes up with a bogus looking address in Massachusetts:

Registrant Email: info@dedicatedland.com
Registry Admin ID: Not Available From Registry
Admin Name: Mizban Web Paytakht LLC
Admin Organization: irnameserver.com
Admin Street: Newton Center 
Admin City: Newton Center
Admin State/Province: Massachusetts
Admin Postal Code: 00000
Admin Country: US
Admin Phone: +1.00000000
Admin Phone Ext:
Admin Fax:
Admin Fax Ext: 


However RIPE show them as being in Tehran:
Mizban Web Paytakht Co. Ltd.

No.43, North Ekhtiyariyeh St, Ekhtiyariyeh Sqr
1958743611 Tehran
IRAN, ISLAMIC REPUBLIC OF

phone:   +98 2122587469
fax:  +98 2122761180
e-mail:  info (at) dedicatedland (dot) com
Anyway, if you are not interested in sending traffic to Iran, Mizban Web Paytakht own AS64428 which comprises of 185.165.40.0/22 as well. I'll make a guess that the 188.165.162.200/29 range
may be insecure and could be worth blocking.

The email itself originates from 104.171.114.204 which is allocated as follows:

CustName:       jason Richards

You probably don't need to accept .z attachments at your mail perimeter, and any decent anti-spam tool should be able to look inside archives to determine was is in there.

Evil network: Fast Serv Inc / Qhoster.com

Checking these IOCs for this latest Flash 0-day came up with an interesting IP address of 89.45.67.107 which belongs to Fast Serv Inc aka Qhoster, probably of Bulgaria but masquerading themselves as a Belize outfit.

I came across Fast Serv / Qhoster a lot last year during the Angler EK epidemic, where they had entire ranges full of badness, often with no discernable legitimate sites at all. It turns out that I'd blocked the /24 a year ago as it was full of EK servers. The full analysis I did of Fast Serv / Qhoster Angler ranges can be found in these Pastebins: [1] [2] [3] [4] [5] [6] [7]

So, this Flash 0 day gave me a renewed impetus to identify these ranges and keep them the hell off my network. Luckily HE's BGP tool can identify most of the allocated IPs of a /24 size or larger [8] [9] plus a bit of infill from other sources.

I can't guarantee that these ranges are free of legitimate sites, but even a quick glance at some of the ranges (the BGP tool is quite good for this [10]) shows signs of obvious badness in almost all of them. Use at your own risk :)

Note that these ranges are across many different ASes and hosts, although AS201630 is allocated to Qhoster themselves.

There are lots of suspect things about this domain registration - the address is clearly fake, the registrar is based in South Africa and the nameservers are in Russia, and also it was registered just a few weeks ago. A quick bit of Googling around shows that "Nelson Ozi" is also linked to the following probably fraudulent domains:

svbfib.com
svbfibem.com
globalcreditsus.com

These all seem to be connected with an IP range 169.255.59.0/24 (Web4Africa again) which does seem to have a lot of scammy sites hosted on it. Blocking access to that range might be prudent.

The spam email itself comes via another Russian server mail.elmeh.ru but this particular email originated from 103.207.37.101 in Vietnam. Replies to the champ-footballacademyagency.co.uk email would be set to mx.yandex.net which is in Russia again.

It would probably be quite difficult to stuff any more dodgy indicators into this spam. What the scam actually is isn't 100% clear, it could be anything from a simple advanced fee fraud all the way up to child abduction. Avoid.
