本程式碼可以實現C&C即command and control center的功能，可以新增被控端，然後同時發出相關的指令，並獲得相應的結果：

 1 import paramiko
 2 import sys
 3 
 4 class SSHClient:                                        #該類用於產生各個被控端，可以執行相應的Shell指令
 5     def __init__(self, host, username, password) -> None:
 6         self.host = host
 7
 
         self.username = username
 8         self.password = password
 9         try:
10             self.sshclient = paramiko.SSHClient()
11             self.sshclient.set_missing_host_key_policy(paramiko.AutoAddPolicy())
12             self.sshclient.connect(hostname=self.host, username=self.username, password=self.password)
 
13         except paramiko.AuthenticationException:
14             print("[-] Failed to connect %s" % self.host)
15

18         try:                 
19             stdin, stdout,stderr = self.sshclient.exec_command(command)
20             if stdout:
 
21                 command_result = stdout.read().decode('utf-8')            
22             return command_result
23         except Exception as e:
24             print(e)
25             return "Failed to execute command on the host: %s" % self.host

　　執行效果如下圖所示：
