#cybersecurity #ctf #oscp
In this video I walk through the TryHackMe room “Jax Sucks Alot” from start to finish, focusing on a Node.js deserialization vulnerability. This is an educational, ethical penetration-testing walkthrough designed to teach how these issues are discovered, validated in a lab, and properly mitigated.

What you’ll get in this video:

Explanation of deserialization in Node.js and why it’s dangerous (concepts & indicators)

Live demo of the exploitation workflow in a controlled TryHackMe environment (for learning) — no malicious guidance for real-world attacks

How to analyze evidence and verify impact safely
Resources to learn more and practice legally

Who this is for:

Students doing TryHackMe/CTF challenges

Junior pentesters learning about Node.js/web vulnerabilities

Developers who want to harden Node.js apps against deserialization issues

Security enthusiasts who want safe, practical learning paths
