This blog is my personal space to share knowledge, insights, and hard-earned lessons from the world of cybersecurity.
I primarily publish:
- Hack The Box (HTB) writeups
- Pentesting cheatsheets
- Notes, tools, and observations from real-world CTFs, labs, and research
Whether you’re a beginner looking to learn, or a seasoned hacker looking to swap notes — I hope you’ll find something useful here.
🤔 Why “Cubit” or “copper_nail”?
It all started with my nickname — “cu” is short for Copper, and I liked the sound of it.
- Cubit plays on that, combining “cu” with a unit of measurement — fitting for a blog that measures progress, skills, and notes in cybersecurity.
- Later, copper_nail felt even more appropriate: copper for conductivity (think networks, circuits), and nail for pinning down knowledge. It’s a metaphor — this blog is where I hammer in the details that matter.
Whether it’s a writeup, a cheatsheet, or a quick note from a late-night pwn — this is where I store and share what I learn.
