**代码流程：**
1. 创建一个新的管道
2. 创建并启动一个连接到创建的管道并写入一些内容的服务。服务代码将执行以下编码的PowerShell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. 服务从管道中接收来自客户端的数据，调用ImpersonateNamedPipeClient并等待服务完成
4. 最后，使用从服务获取的令牌生成一个新的_cmd.exe_
