原理

  1. Python檔(Client)運行後就會連接Server,然後進行Key Exchange,流程大概就是Server產生RSA key pair,把public key傳到Client,Client產生AES-128的key和IV, Client用RSA public key加密AES key傳回Server然後用private key解密,之後Server和Client用AES CBC通訊。
  2. Server會把Python的payload加密後傳到Client,Client解密後用exec()函數執行惡意Payload,把結果加密後傳回Server。
  3. Server可以把預先做好的第三方庫的zip檔加密後傳到Client,Client解密後會把zip解壓在某個temporary folder,再由temporary folder import,這樣一樣就算Client沒有該Libaray,也可以在Client安裝
