⚙️CRTP Methodology

This Methodology is intended to help to stay focus and don't miss anything during the exam.

Important to know:

CRTP consists on Live Of The Land then no phishing, no exploits, and no CVEs.

The exam environment won't include any tools, but we can add the tools we need to a specific folder in Windows Defender exclusion settings.

What you have learned in the course is everything you need in order to pass the exam.

The exam goal is to execute OS command on 5 targets not matter what privileges the user have
