Overview

This is a PowerShell script to automate client pentests / checkups - at least to a certain extend.
You can use it together with my PwnDoc vulns to further get rid of unneccessary work -> https://github.com/LuemmelSec/PwnDoc-Vulns

How

If possible run as Admin, otherwise some checks might / will fail.

. .\Client-Checker.ps1

or

import-module .\Client-Checker.ps1

or

iex(new-object net.webclient).downloadstring("https://raw.githubusercontent.com/LuemmelSec/Client-Checker/main/Client-Checker.ps1")

then just

Client-Checker

The looks

You will have a detailed section which gets generated on the fly with a category, what the script found as well as links to resources for more detail, abuse paths and remmediations.

At the very end you will get a tabular overview that will help you to quickly get an overview of all checks done.
