Hey, I’m Kar0n

I’m a cybersecurity enthusiast and aspiring ethical hacker, currently focused on learning penetration testing and offensive security.
This blog is my personal knowledge base — built to help me study, stay organized, and grow in the field.

I hold a Master’s degree in Cybersecurity from UNS Łódź (University of Applied Sciences, Poland).

What I do

  • Practice web, network, and Active Directory exploitation
  • Study for certifications like OSCP, PNPT, and CPTS
  • Solve labs and machines from Hack The Box and TryHackMe
  • Document notes, cheatsheets, and walkthroughs for future reference
  • Learn, break, fix, and learn again

Why I Built This Site

There’s a ton of great material online — I use it too — but I believe that
writing your own notes is the fastest way to actually learn.

I collect, adapt, and simplify content to suit how I learn best.
This site is my external brain, and if it helps someone else along the way — even better.

Goals

  • Achieve mastery in core pentesting areas
  • Earn top-tier certifications
  • Contribute back to the infosec community
  • Never stop learning

Thanks for visiting — feel free to check out the notes or reach out if you’re on a similar path.

Stay curious and keep hacking!
