Bio​

I'm a 24-year-old cybersecurity enthusiast, student, researcher at FTZ CyberSec and CTF player based in Hamburg.
Driven by a deep passion for cybersecurity, I'm actively exploring penetration testing and ethical hacking, with the goal of becoming a professional pentester. Currently, I'm gaining hands-on experience through bug bounty hunting and gradually shifting my focus toward Red Teaming to deepen my offensive security skillset.
My journey began with game hacking, which sparked my interest in reverse engineering and binary exploitation and now naturally extends into more advanced adversarial simulation techniques.
Outside of cybersecurity, I enjoy a wide range of hobbies like self development, cycling, kayaking, gaming, ricing Linux environments and visiting hackerspaces.

Areas of Focus​

CTF-Team: Actively leading TraveTrickstersLegion at university level, learning together and exchanging our knowledge.
CTFs: Solving realistic security challenges and journal them to continuely expand my knowledge base.
Offensive Security: Practicing and studying techniques to simulate real-world attacks on systems and networks.
Red Teaming: Emulating advanced threat actors to assess organizational security from an adversarial perspective.
Bug Bounties: Identifying and responsibly disclosing security flaws in real-world applications and platforms for rewards and experience.
Reverse Engineering: Analyzing binaries and software internals to understand behavior and uncover vulnerabilities.
Binary Exploitation: Developing and executing exploits targeting low-level vulnerabilities like buffer overflows and memory corruption.
Vulnerability Research: Investigating software, protocols, and systems to discover new security weaknesses and exploitation vectors.

Current Projects​

  • Building and testing Hardware Tools with Arduino, ESP8266, ESP32 and Raspberry Pi's
  • Reversing and Pentesting E-Scooters (Pre-Project for Car Hacking)
  • Building a mobile Sandbox as Pentesting Lab
  • Creating my own Pentesting Framework with all Software/Tools I use
  • Guides on Github

Principles​

  • Constantly expanding my knowledge base
  • Advocate of the CCC's hacker ethics
