This sole purpose of the information contained in this advisory is
to point out the flaws in InterNIC's domain name handling system
and is intented for education. Any abuse of the information in whole
or in part is NOT my responsibility nor do I encourage illegal activities.
The below mentioned technique involves a planned step by step way
of stealing different sorts of com/net/org/gov/mil domain names.
______
Tools:
------
* anonymous remailer or mail bomber which could spoof email adresses (I used Kaboom).
* access to internet and mainly networksolutions.com website.
* Social Engineering skills for timing the emails.
* A fake email address at hotmail.com or any other free service.
____________
Intructions:
------------
As an example for this advisory, I will take the domain name wi2000.org.
Go to networksolutions.com and click on the link that says 'Who Is.'
Now enter the domain name (wi2000.org in this case) in the search field
and click on the 'Search' button.
This would show you the WhoIs information as shown below

Registrant:

Domain servers in listed order:
NS1.CAN-HOST.COM 24.215.1.6
NS2.MOUNTAINCABLE.NET 24.215.0.12
____________________________________________________________
Now you have two choices here:
-01> Either you could take full control of the domain by
changing the Administrator's handle information.
OR
-02> You could simply point the domain to another
host and let it recover in time by itself.
The first approach is very aggressive and could be hazardous if you are
going for gov or mil domain names so I recommend second approach for gov
and mil domains.
___________________________
Intiating the First Attack:
---------------------------
Let me first explain the InterNIC authentication system in case most of you
would be the readers who do not have their own domain names.
The problem with InterNIC authentication is that they do NOT send a
confirmation email if the request is sent from the same email as the
person owning the contact or the domain name itself!
Therefore, utilizing this flaw one could spoof anyone's email address
and change any domain name's information.
Although, a confirmation is required from the person to whom the domain
is about to be transferred; and that shouldn't be too hard as it would
your own email address ;-)
Here's a step by step procedure:
- Go to http://www.networksolutions.com/
- Click on the link that says 'Make Changes.'
- Enter the domain name wi2000.org
- You should be presented with 2 blue buttons
- Click on the one that says *Expert*
- Next screen would have a heading 'Select the form that meets your needs'
- Click on the link that say 'Contact Form'
- Next you should see a form with 2 fields.
- In the first field enter the admin's handle (wi2000.org admin is AMM367)
- In the next field enter his/her email address
(in this case it's HACKEDINDUSTRIES@HOTMAIL.COM)
- Change the option to 'Modify.'
- Now 'Proceed to Contact Information.'
- Select the MAIL-FROM option and click the 'Go on to Contact Data Information.'
- Now you should see all the information about the admin contact of domain name!
- In the E-mail address field change the email to your own fake email.
(I changed it to dd@doom.com)
- Now 'Proceed to Set Authorization Scheme.'
- Again choose MAIL-FROM and enter the email address of the admin
(HACKEDINDUSTRIES@HOTMAIL.COM)
- Leave the bottom option to 'No' and 'Generate Contact Form.'
- Now you should see a template with all the information. Similar to this:

_______________________________________________________________________
You should now be thinking that this message could get you in trouble but
there is a way of getting rid of this trouble. Here you'll use your mailbomber
to mailbomb the guy with 20-30 similar messages if you want your attack to be
successful. The person would see 35 messages from the same address and therefore
would delete all of them and you'd probably be safe. If he 'would' email someone
then he would probably reply to the wrong tracking number. In the above case,
the tracking number is [NIC-000128.4r50]. OK, here another hard part. You have
to open your notepad and generate similar numbers actually come up with them.
You should NEVER mailbomb the person with the same tracking number. What I mean
is that you should never send more than one emails to him from [NIC-000128.4r50]
in the next email, change the [NIC-000128.4r50] to [NIC-000127.5089] or something
different. Here is a list of some numbers that I generated just to give you
a good idea of how the scheme works.
[NIC-000127.5089]
[NIC-000128.4rg7]
[NIC-000128.523f]
[NIC-000127.53d0]
[NIC-000129.r609]
[NIC-000128.3f6y]
[NIC-000128.5d8t]
[NIC-000127.r509]
[NIC-000128.4r30]
[NIC-000127.d307]
_____
NOTE: Remember to change the number at both places. In the subject as well as the email
----- body!
In the case of wi2000.org you will send the email messages to HACKEDINDUSTRIES@HOTMAIL.COM
from hostmaster@internic.net. The message subject and body are already described above.
Stop after you have mailed him/her 10-15 messages! Now it's time to email
hostmaster@networksolutions.com with our fake email as HACKEDINDUSTRIES@HOTMAIL.COM
So again, in this case the message will be sent to hostmaster@networksolutions.com
from HACKEDINDUSTRIES@HOTMAIL.COM with the following template that we created above:
______________________________________________________________________________

________________________________________________________________________________
_____
NOTE: Do NOT put anything in the Subject!
-----
Just send one email! Do NOT bomb hostmaster@networksolutions.com with more than one
emails!! That's pretty much it. Now continue to bomb HACKEDINDUSTRIES@HOTMAIL.COM,
changing the tracking number everytime until your 30-35 tracking numbers are used up!
Now all you gotta do it WAIT. After 24 hours you could go and change the domain
information and no one would be there to stop you because now you are the admin
of the domain name!
_____
NOTE: This attack will only work on domains that have an admin contact different
----- from their technical contact!
____________________________
Intiating the Second Attack:
----------------------------
This attack will be successful even if the technical and admin contact are the
same but the admin of the contact needs to be kind of stupid to disregard
emails from interNIC as he is also the technical contact; but this method should
work as it has worked for me.
The procedure is basically the same apart from the fact that this time:
- Go to http://www.networksolutions.com/
- Click on the link that says 'Make Changes.'
- Enter the domain name wi2000.org
- You should be presented with 2 blue buttons
- Click on the one that says *Expert*
- Next screen would have a heading 'Select the form that meets your needs'
- Click on the link that say 'Service Agreement.'
- Now when it asks for email address, enter your own.
- Now you should see many fields, don't panic!
- Go to the technical contact and change the handle to freeservers, hypermart e.t.c.
- Now come to 'Nameserver Information.'
- Change the nameservers to hypermart or freeserver nameservers.
- If there's anything in the 'Optional Information' after that then
simply delete them.
- Click on the button 'Submit this form for processing.'
- You are done, the form will be emailed to your email address.
- When the form arrives in your email, then simply take this part:

For instructions, please refer to:
"http://www.networksolutions.com/help/inst-mod.html"
____________________________________________________________________________________
- Now launch your anonymous remailer or mailbomber.
- From: the domain admin (HACKEDINDUSTRIES@HOTMAIL.COM in this case).
- To: hostmaster@networksolutions.com
- Subject: (do not enter any subject, leave the field blank!)
- Body: the template you created above.
- You are ready to go but before you send this email to InterNIC,
remember to bomb HACKEDINDUSTRIES@HOTMAIL.COM with similar emails
but different tracking numbers as we did in the first procedure.
- After sending 10-20 emails, send the above template to InterNIC.
- Continue bombing your 40 messages. Remember to generate 40-50
tracking numbers.
- This is basically it.
- The domain would be transferred to freeservers or hypermart
and then you could simply activate it from there on your own email
address. Remember to use a fake email.

Nameservers and Handles:
------------------------
Freeservers Technical Handle: FS4394
Primary Nameserver: NS3.FREESERVERS.COM
Primary Nameserver IP Address: 209.210.67.153
Secondary Nameserver: NS4.FREESERVERS.COM
Secondary Nameserver IP Address: 209.210.67.154
Hypermart Technical Handle: DA3706-ORG

Primary Nameserver IP Address: 206.253.222.65
Secondary Nameserver: NS2.HYPERMART.NET
Secondary Nameserver IP Address: 206.253.222.66
_______________
Possible Fixes:
---------------
As you have seen, InterNIC does not use the tracking number system too
efficiently. Possible fixes would certainly be a confirmation email to
the admin contact 'with' a tracking number. NOT the email saying 'Your request
is being processed' but a confirmation email which would ask, 'Do you agree
with this request?' even if it has been sent from the same email address as admin's!
Tracking numbers could be easily generated and the attacks I have mentioned
above aren't too hard for a script kiddie wi
