Summary
The sole purpose of the information contained in this advisory is to point out the flaws in InterNIC\'s domain name handling system and is intended for educational use only. Since this is public knowledge, it should be also in everyone\'s reach.
The technique described below involves an easy to follow procedure of stealing .com/.net/.org/.gov/.mil domain names.
This vulnerability has been publicly known for quite a while, and there are ways to prevent it (See below).
The procedure below enables an attacker to take over a domain name, enabling him or her to make the arbitrary web address (http://www.example.com) point to any desired web page on the Internet. This method of domain hijacking is constantly being used to hijack domain names, and to deface web sites.


Details
Required ingredients:
* Anonymous remailer or mail bomber that can spoof email addresses.
* Social Engineering skills for timing the emails.
* A fake email address at hotmail.com or any other free service.

Exploit:
As an example for this advisory, we will take the domain name example.org. Go to http://www.networksolutions.com and click on the link that says \'Who Is.\' Now enter the domain name (example.org in this case) in the search field and click on the \'Search\' button. This would show you the WhoIs information, which will be similar to the one shown below:

Registrant:
Example (ex24-DOM)
Address details

Domain Name: EXAMPLE.ORG

Administrative Contact, Technical Contact, Zone Contact, Billing Contact:
DOMAIN, ADMIN (ADM001) ADMINEMAIL@EXAMPLE.COM


Record last updated on 00-Jan-2000.
Record created on 00-Jan-2000.
Database last updated on 3-Feb-2000 14:29:53 EST.

Domain servers in listed order:

NS1.EXAMPLE.COM 1.2.3.4
NS2.EXAMPLE.NET 1.2.3.5


Now you have two choices:

1) Either you could take full control of the domain by changing the Administrator\'s handle information.
Or
2) You could simply point the domain to another host and let it recover in time by itself.


Initiating the First Attack:

Let us 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 example.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 (example.org admin is ADM001)
- In the next field enter his/her email address (in this case it\'s ADMINEMAIL@EXAMPLE.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. (in this case it\'s evil@domain.com)
- Now \'Proceed to Set Authorization Scheme.\'
- Again choose MAIL-FROM and enter the email address of the admin (ADMINEMAIL@EXAMPLE.COM)
- Leave the bottom option to \'No\' and \'Generate Contact Form.\'
- Now you should see a template with all the information. Similar to this:

******** Please DO NOT REMOVE Version Number ********

Contact Version Number: 1.0

******** Please see attached detailed instructions ********

NOTE: Do NOT press the button at the bottom that says \'Mail this contact form to me!\'

Copy and paste this message into your anonymous remailer or mailbomber and you are ready to go; but WAIT! It\'s not that easy, now comes the HARD part! When you mail this message tohostmaster@networksolutions.com a message similar to the following would be sent to the admin email address:


Subject: [NIC-000128.4r50] Your Mail
__________________________________________________ ____________

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 we 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 we 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]

Remember to change the number at both places. In the subject as well as the email body!

In the case of example.org you will send the email messages to ADMINEMAIL@EXAMPLE.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 ADMINEMAIL@EXAMPLE.COM So again, in this case the message will be sent to hostmaster@networksolutions.com from ADMINEMAIL@EXAMPLE.COM with the following template that we created above:

******** Please DO NOT REMOVE Version Number ********

Contact Version Number: 1.0

******** Please see attached detailed instructions ********

Authorization
0a. (N)ew (M)odify (D)elete.: Modify
0b. Auth Scheme.............: MAIL-FROM
0c. Auth Info...............:

1b. (I)ndividual ®ole.....: Individual
1c. Name....................: DOMAIN, ADMIN
1d. Organization Name.......: EXAMPLE

2b. Notify Use..............: AFTER-USE

Authentication
3a. Auth Scheme.............: MAIL-FROM
3b. Auth Info...............: ADMINEMAIL@EXAMPLE.COM
3c. Public (Y/N)............: NO


NOTE: Do NOT put anything in the Subject!

Just send one email! Do NOT bomb hostmaster@networksolutions.com with more than one email. That\'s pretty much it. Now continue to bomb ADMINEMAIL@EXAMPLE.COM, changing the tracking number every time until your 30-35 tracking numbers are used up!

Now all you have to do is 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!


Initiating the Second Attack:

This attack will be successful even if the technical and admin contact are the same.
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 example.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:

**** PLEASE DO NOT REMOVE Version Number or any of the information below when submitting this template to hostmaster@networksolutions.com. *****

END OF AGREEMENT


For instructions, please refer to:
\"http://www.networksolutions.com/help/inst-mod.html\"


- Now launch your anonymous remailer or mailbomber.
- From: the domain admin (ADMINEMAIL@EXAMPLE.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 ADMINEMAIL@EXAMPLE.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: NS1.HYPERMART.NET
Primary Nameserver IP Address: 206.253.222.65
Secondary Nameserver: NS2.HYPERMART.NET
Secondary Nameserver IP Address: 206.253.222.66

TiP...
Possible Fixes:
Enable the CRYPT-FW password mechanism. This should prevent anyone without this password from changing your domain information (see the Internic contact form for more information
