About this journal

null.journal is a quiet corner of the internet where I document what I learn while working through hacking platforms, CTFs, and security research. No ads. No newsletters. No dark patterns. Just notes.

The writing here falls into three buckets:

  • Writeups — full walkthroughs of machines I've compromised: Hack The Box, TryHackMe, VulnHub, CTFs. Enumeration, exploitation, post-exploitation, and what I'd do differently next time.
  • Notes — short-form entries on a single tool, trick, or concept. Think of these as pages from a lab notebook that happened to survive the day.
  • whoami — you are here.

Why write any of this down?

Because I forget. Because someone else might be stuck on the same rabbit hole I was in last Tuesday. Because writing something out is the fastest way to find out whether you actually understood it.

Ground rules

  • Writeups for retired boxes or completed CTFs only, unless stated otherwise.
  • Nothing on this site is novel research — assume everything here is well known to someone who knows more than me.
  • No trackers, no analytics, no cookies, no third-party scripts. Inspect the source if you want to verify.
