PowerShell for Pentesters

Really good course: https://github.com/dievus/PowerShellForPentesters

This is a mini-cheat sheet with some useful commands. If you want to learn properly then do the course above.

Useful Functions

# Convert a file to Base64
[convert]::ToBase64String((Get-Content -path "your_file_path" -Encoding byte))

The above comes in handy for file extraction because you can just copy the Base64 String to another box and decode then pipe to a file

# Encode String as Base64
[Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes('Motörhead'))

# Decode from Base64 String
[Text.Encoding]::Utf8.GetString([Convert]::FromBase64String('TW90w7ZyaGVhZA=='))
