Creating backdoor in any window , without using previous password

Creating backdoor in any window . Lets assume
that you have just cracked victim's windows
password. or simply got access to his windows for some time.

Can you make some changes in windows so that you
could access the windows again even if victim
changes the password ?? or Can you make any changes
in your own windows so that you could access it
anytime even if anybody sets/changes password ?
Simply Can we set a backdoor in windows ?

Yes we can :) .
Backdoor actually means maintaining access.
okay lets do one thing first. Open your command
prompt (run as administrator in win 7/vista).

Type the following command : 

Syntax : net user account.name *
Example: net user administrator *
and hit enter. Set any password for that account.

Hopefully your new password must have been set.
did you notice one thing ? It didn't ask you to confirm
old password. Now suppose if anyhow we manage to access
command prompt at logon screen (without logging in), we
can easily change/clear password. Okay lets move on.
Now press shift key five times and you must have got a
dialog box "sticky keys" on screen.

Sticky keys is a feature that makes it easy for users
who have physical disablilities to press multiple keys
at time. This is the only feature which can be used
before logging in at logon screen ( as per my knowledge).
I repeat this feature can be used at logon screen by
pressing shift key five times.
Whenevr we start an application like paint, we are
actually running mspaint.exe placed inC:\windows\system32.
or command prompt, we are running cmd.exe placed in system32
directory, similary
When we press shift key 5 times or use sticky keys feature,
system actually starts the executable file sethc.exe placed
in system32 directory. This means if we rename cmd.exe to
sethc.exe and press shift 5 times, system would again start
sethc.exe but instead of sticky keys the command prompt will
be opened. But you just cant simply rename it or change
system32 files. Follow the tutorial for that.

Tutorial :

* Go to C:\windows\system32 

* Copy cmd.exe on your desktop and rename it to sethc.exe . 

*Now copy that file and paste again in system32 directory. 

@ Windows XP Users

Hopefully existing orignal sethc.exe must have been replaced 

and your job is done. Now press shift five times and you 

would see command prompt on screen.You can access command 

prompt at windows logon screen and change/clear the password 

easily using "net user" command. 

Note: You can also do these changes while using windows Guest 

Account. But when you would access command prompt at logon 

screen, you can change/clear password even of administrator's 

account. This is exactly how , we can hack into administrator's 

account through guest account. 

@ Windows vista/7 Users

You must have got a pop up box saying "Access Denied". 

Actually you can not change system32 directory files 

until you do not have the permissions. You can not 

have the permissions until you do not have the ownership. 

So lets take ownership, change permissions, just follow the steps. 

1. Right click on sethc.exe and run as administrator. 

Again right click on sethc.exe, open properties. 

Click on Advanced tab , then on owner and click edit, 

change the owner from "trusted installer" to "administrator" 

and click apply. 

2. Then click on 'Edit' in security tab to edit permissions. 

Click on 'Administrators' , give it full control and apply changes. 

Okay its done now. 

Now try replacing the orignal sethc.exe with our sethc.exe 

(got by renaming cmd.exe). Press shift key five times and 

hopefully you would get command prompt on the screen instead of sticky keys. 

Enjoy Command prompt at logon screen... 

So do not forget to set this backdoor whenever you would 

get friend's laptop for a few minutes... :)
