About Me

Cybersecurity Master's student based in Sweden, mixing academic depth with hands‑on labs, CTFs, and real‑world security projects.

Interests span threat intelligence, penetration testing, OSINT, and security architecture, with a growing focus on IoT and automotive security.

Outside of hacking and hardening, there is a love for flight simulators, tech tinkering, and turning complex security topics into accessible stories through blogs and write‑ups.

📡 IoT Security Analysis Project

Context. Analyzed vulnerabilities in smart siren and light devices during the Cybersecurity Exchange Program at the University of Twente.[file:38]

What I did.

Mapped device attack surface and communication flows
Identified exposure and misconfigurations in device behavior
Applied practical threat modeling to prioritize weaknesses

Impact. Produced a comprehensive report with remediation strategies and concrete security recommendations for hardening the IoT setup.[file:38]

🚘 ISO/SAE 21434 Industry Implementation Review

Context. Academic literature review on how organizations implement ISO/SAE 21434 for automotive cybersecurity in real environments.[file:38]

What I did.

Surveyed industry papers on TARA and lifecycle security processes
Compared effectiveness measurement approaches and gaps
Evaluated current automation tooling across the vehicle lifecycle

Impact. Highlighted adoption challenges, measurement blind‑spots, and where automation helps or fails, forming a base for future research.[file:38]

🧪 Labs, CTFs & Ongoing Work

Context. Continuous practice environment across small labs, CTFs, and notes used to build intuition and repeatable workflows.

What I do.

Set up focused labs around web, network, and OSINT scenarios
Work through CTF challenges targeted at fundamentals
Capture methodologies and mistakes in structured write‑ups

Impact. Builds real muscle memory and personal playbooks rather than just theoretical knowledge.

Labs & CTF Mindset

Homelab & experiments

Minimal homelab used to simulate attacks, collect logs, and observe how activity looks from the defender’s point of view.

Includes experiments with basic log collection, simple detections, and documenting how different kinds of noise show up in telemetry.

CTF approach

Treats CTFs as a training ground for structured thinking: recon → enumeration → exploitation → reporting, not just “guessing the trick”.[web:84]

Focused on challenges that map to real‑world skills: web vulns, misconfigurations, simple privilege escalation, and OSINT trails.
