HackTheBox UniCTF 2022 Talk - Variable is what you make of It

From a channel Lumen includes in full: IppSec is a dedicated cybersecurity teaching channel whose uploads are methodical walkthroughs of how to attack and defend systems. Every available transcript explains techniques step by step, from nmap flags and Active Directory attack chains to tmux usage and incident-response analysis. Titles are plain and descriptive, with no clickbait, and the channel has no entertainment, review or hype content, so the whole channel fits; title patterns catch any stray live or promo uploads.
