The result on 48hours+ in battle with Kelihos < request for FURTHER block/dismantle cooperation & support. #Tango is going down..

This post is dedicated to many.. so many of wonderful individuals involved with the effort to stand against Kelihos P2P malware infection. This is an example on WHAT CAN BE DONE if InfoSec are gathered to fight malware infection. This report is totally an effort of a team contains members who simply believe the same dream, to free our internet from malware. We cannot make a list of your (so many) names but we are all know who you are and what you did. Sincerely respect with thank you very much. There were many bumpy communication was initially made, for the tense and rogue communication we apology to every inconveniences. I personally am so happy to live in an era of gentlemen like you are! #MalwareMustDie!

First, you need to know what the Kelihos Botnet & malware threat is, our previous post gives you good illustration about the threat here-->>[Previous Post]. As per you maybe noticed in the our twitter timeline, we are doing our best effort in battle with the Kelihos malware scum, yes we were haunted by this infection via RedKit Exploit Kits, TDSS, direct spam or via its botnet self-updating function itself and this "scum" still out there and feeling happy-ever-after infecting us, we just can not accept this fact.

Therefore we executed every possible effort that can be done as a bunch of volunteers of an NPO entity to suppress their growth in internet. As the efforts itself is varied from suspension, sinkhole, DNSBL block, VT/URLQuery (+etc) blacklisting, OpenDNS/GoogleDNS blocking, parallel with bunch of reports to the regional basis authorities (CERTs, GroupIB, ISPs, Registrar, ICANN, Microsoft) and to varied Sinkhole entities.

We recieved the great help and support from the people in the entities mentioned above, and also with a perfect work delegation between our team in twitter so we are able to gain a good fight and successfully resulted some good achivements within 48hours+. It is unfair to let people who help and support us by seeing only twitter as result that's why I posted our effort's report here, together with some tips and tricks used in fighting this infection in our beloved MalwareMustDie blog.

And this post is the report of the mentioned effort. Here we go..

1. Stopping the new Kelihos NS based .COM services

By the time we started this effort, Kelihos started to switch their DNS from something with ns[1-6]."\][a-z]\{7\,8\}\.".RU into the .COM tld domains with the format ns[1-6]."\][a-z]\{7\}\.".COM , we found that all of the domains was released by INTERNET.BS a well-known registrar of being abused by the cybercrime to release their infector domains. And with the great help from the very dedicated individuals mentioned above we took these domains (see below) off internet:

DUSSEVA.COM
BEUHNIM.COM
GULFKAT.COM
ZUNCHER.COM
FLOWSRE.COM
OMBUGEW.COM
WIDERAT.COM
DAVUJUZ.COM
XEXUMYB.COM
KAROZGI.COM
OSIKKID.COM
NIGUCGU.COM
below is the PoC of the suspension and sinkholing result:

This is how they got into internet:

The following is some of PoC and hard evidence of the .COM that Kelihos used are in the extracted INTERNET.BS released domains database-->>[PASTEBIN]

2. The dismantling effort of .RU infectors

Currently, the main basis of the Kelihos infecion are using the .RU basis ccTLD domain. It is very important to suppress their growth in their home-base also. With the great coordination and help fro GroupIB we made effort to dismantle the other "NEW" 101 .RU "weaponized domains as per listed below:

3. How we PoC an NS infector in commercial TLD

This is how we always PoC the new infector in the wild, we share this as a know how for everyone to help to be able to spot and report the new infection, we use our PoC for OSIKKID.COM as per below:

'(1) Spreads the HLUX as per below checks:'

bash-3.2$ date
Thu Aug  8 12:57:18 JST 2013

// the HLUX IP..

bash-3.2$ while true; do dig +short OSIKKID.COM; sleep 1; done

[...]

'(2) Serving Payload malware of Kelihos'
and every A records is serving Kelihos payload:
// Below is the currently download PoC:

'(3) INTERNET.BS registration is current MO.'
It is proven behind the registration process of this domains
We tried to remotely extracted the registrar: INTERNET.BS released 
domain from current day until Jun the 1st, and this domain is one of it:

bash-3.2$ whois osikkid.com
Whois Server Version 2.0
Domain names in the .com and .net domains can now be registered
with many different competing registrars. Go to http://www.internic.net
for detailed information.
   Domain Name: OSIKKID.COM
   Registrar: INTERNET.BS CORP.
   Whois Server: whois.internet.bs
   Referral URL: http://www.internet.bs
   Name Server: NS1.OSIKKID.COM
   Name Server: NS2.OSIKKID.COM
   Name Server: NS3.OSIKKID.COM
   Name Server: NS4.OSIKKID.COM
   Name Server: NS5.OSIKKID.COM
   Name Server: NS6.OSIKKID.COM
   Status: clientTransferProhibited
   Updated Date: 06-aug-2013
   Creation Date: 18-jun-2013
   Expiration Date: 18-jun-2014
>>> Last update of whois database: Thu, 08 Aug 2013 04:03:30 UTC <<<

'(4) The linked DNS services used with the previous Kelihos reported NS services:'

The NS1. of this domains is linked with the same NS as previous reported:
ns1.OSIKKID.COM = ns3.davujuz.com
ns2.OSIKKID.COM = ns5.ns4, ns2.ns4.ombugew.com
ns3.OSIKKID.COM = ns1.davujuz.com
...and so on...

'(5) The infection raised in RU are causing by OSIKKD.COM NS server:'
The 100 domains RU are needed to be blocked with the same pattern as we previously reported to Group IB, under REGGI.RU, (and FYI the abuse of the RU by the kelihos is more than 12,000 domains not included this one... )
This is the PoC that the domains of RU was registered 24hrs more under the OSIKKD.COM NS :
domain:        ACBIMNIK.RU
nserver:       ns1.osikkid.com.
nserver:       ns2.osikkid.com.
nserver:       ns3.osikkid.com.
nserver:       ns4.osikkid.com.
nserver:       ns5.osikkid.com.
nserver:       ns6.osikkid.com.
state:         REGISTERED, DELEGATED, UNVERIFIED
person:        Private Person
registrar:     REGGI-REG-RIPN
admin-contact: https://panel.reggi.ru/user/whois/webmail/
created:       2013.08.06
paid-till:     2014.08.06
free-date:     2014.09.06

Below is the check of the reported RU affiliated by the NS of the OSIKKID.COM crossed by the IP and DNS:

ACBIMNIK.RU,,      ns1.osikkid.com.
      ns2.osikkid.com.
      ns3.osikkid.com.
      ns4.osikkid.com.
      ns5.osikkid.com.

      ns6.osikkid.com.

4. Monitoring The Actual Infection Range

As per today before the NS sinkholing on effect, with the great effort of our members we monitor the infection of the 1,287 IP address actively distributing Kelihos malware payload all over the world as per listed in our pastebin here-->>[LINK]

You can add the /rasta01.exe after the IP to get the latest Kelihos sample payload for your research purpose, as per below sample:

The below binary files also can be used for the same monitoring purpose:

/keybex4.exe
/bljat01.exe
/cuper01.exe
/rasta01.exe
/calc.exe

These infection is plotted in the good graphical interface by Chris J Wilson as per below:

Infection based per ASN:




Infection based by country:


Prologue

The effort is not stopping now.. see below:

And what a FAST action from our friends!! See the time stamp in the tweets, it is AMAZING to suspend & sinkhole malware domains THAT fast! :-)) (you guys rocks!!)
We work hard on trying to break this "Kelihos" legend methodologically and the method works!
Don't ever let the Kelihos scums enter the internet! Spot & stop them instantly, cooperate with the abused registrar to get the new infectors go to sinkholes and to suspend those new domains instantly.
They weakness is in their DNS, these services backboned their payload distribions of thousands IP and infector domains. And those DNS are using static addresses of un-removeable machines. This IS a target to be shutdown!
Thus, DO NOT let those NS getting any domains in our internet! Is not easy to shift their DNS, it hurts them very bad, they just change the name server domains time after time. And right now they need to have a non-RU domains for their DNS to survive their botnet longer.
Let's build the procedure to SPOT, BLOCK, SUSPEND & CLEAN-UP in one flow altogether!
We need your help, your support in coordination with Kelihos botnet's suppress effort. Please cooperate!

Recent Updates

And even registrar also cooperated beforehand w.o waiting sinkhole :-) Thank you!

Our friend, Chris J Wilson was making great statistic of the latest infection data:

Country base infection data:


AS Number base infection data:

Terrific world map of infection by chris J Wilson:

Graph URL is here-->>[LINK]

After .COM the Kelihos moronz shifts to .ME, .ORG & .INFO
Is an idiotic and pathetic act, they don't know with whom they are dealing with now..
