TryHackMe

TryHackMe is a browser-based cybersecurity training platform where you learn by hacking real, deliberately vulnerable machines in guided “rooms.” It is one of the most popular ways to start in ethical hacking, offering beginner paths, CTF challenges and the annual Advent of Cyber event.

This collection gathers every Cracking Station TryHackMe walkthrough: first rooms such as Welcome, Tutorial, Starting Out in Cyber Sec and Introductory Researching; OpenVPN connection guides for Windows and Linux; and the full Advent of Cyber 2025 series. Each writeup explains the concept, the commands and the reasoning behind every answer.

Written by Mehmood Ali, a certified CEH and CEI instructor, with video walkthroughs on the Mr. Professor YouTube channel. New here? Start with our TryHackMe CTF Writeups & Hacking Roadmap.
