Focus

Hey, I’m Artur, a high schooler with a strong passion for cybersecurity and low-level systems.
I enjoy understanding how systems work internally and how they fail.

  • Reverse Engineering
    x86 / ARM binaries · malware analysis · static & dynamic analysis

  • Exploitation (Pwn)
    memory corruption · ROP fundamentals · intro kernel concepts

  • Network Security
    protocol behavior · traffic inspection · packet sniffing

Skills & Domains (Developing)

  • Binary Fundamentals
    Reading x86 / ARM assembly · basic static & dynamic analysis

  • Reverse Engineering
    Function tracing · control-flow analysis · patching simple checks

  • Exploitation Foundations
    Stack overflows · basic heap concepts · intro ROP chains

  • Debugging & Analysis
    GDB + pwndbg workflows · breakpoints · memory inspection

  • Networking Basics
    TCP/IP fundamentals · packet inspection · protocol behavior analysis

  • Linux Internals
    Process memory · ELF structure · system calls · permissions model

  • CTF Experience
    Forensics and network-focused challenges

Currently Learning

  • PCB design
  • RF hacking
  • Meshtastic networking

Goals for 2026

  • Strengthen foundations in reverse engineering and exploitation
  • Gain deeper understanding of operating system internals
  • Grow through CTF participation, hackathons and cybersecurity projects
