Cybersecurity Student · Vulnerability Analysis · Defensive Security
I'm Nobz, a self-taught cybersecurity student focused on understanding how systems work at a low level — how unexpected behaviors show up in networks and services, and what the real limits of software, hardware and carriers actually are.
My main thing is researching, documenting and learning, always from a defensive, technical and ethical angle.
- Defensive security and system hardening
- Technical analysis of OS behavior
- Mobile networks and IP address assignment
- Automation and scripting with Python and Bash
- Architectural and design constraints analysis
- Clean, reproducible technical documentation
A fast, lightweight desktop app for exploring and analyzing structured datasets (JSON, CSV, SQLite, XML, NDJSON). Built with Rust + Tauri v2 + React 19. Local-first, no cloud, with P2P encrypted sharing.
Experimental research project that attempts to rotate mobile public IP using an Android device over USB controlled via ADB, no root required.
The goal isn't to bypass controls — it's to understand and document:
- The difference between manual UI actions and ADB-executed commands
- How Android's telephony framework actually behaves
- Limits imposed by the OS, modem and mobile carrier
- CGNAT and sticky IPv4 assignment behavior
- Why certain "theoretical" approaches don't work in practice
Includes a Python script for automated testing, before/after IP comparison, real failure logs (not hidden), and full technical documentation so others can replicate, verify and build on top of it.
This repo is meant as a study base, not a magic solution.

I believe understanding a system's limits is a core part of security.
- Everything here is done for educational and research purposes
- No exploits or offensive techniques are published
- All experiments run on personal devices and controlled environments
- Failures are documented too — they teach just as much as successes
Knowing how and why something doesn't work is still valid technical knowledge.
