Hello! I'm Markus Toran, a security researcher and more.
In my free time, I enjoy hiking, board games, and CTF and experimenting with new programming languages. Feel free to connect with me!
I went to school in Karlsruhe, first to the Helmholtz-Gymnasium and later to the Carl-Engler-Schule, graduating there in 2018.
After school, I studied computer science at the KIT. I completed my bachelor degree in november 2021 with a thesis about verification of fairness properties for seat appointment methods. During my masters, I focused on IT Security. I wrote my master's thesis about IT Security and User Experience in the domain of Digital Identities.
After uni I worked as a security consultant at Secorvo in Karlsruhe. Currently, I am working as a researcher at Fraunhofer SIT in Darmstadt.
I hope, my work will contribute to a more secure digital future.
Selected peer-reviewed publications and other published work.

2025 has been a mixed year for me. The Good times were pretty good, but the bad times were so bad.
I gave a talk on CRA (Cyber Resilience Act) at GPN 22 in German. Is was a while ago, but if you want to know a thing or two about CRA, check it out!
The challenge "pls respond" from LakeCTF involved analyzing a network capture file containing SMS messages. Inside the messages are animations, IMelody and wireless vector graphics.
When designing my own website, I drew inspiration from various other people's websites. Here are a few that stood out to me:
I designed and printed my own personal asset labels to tag my belongings. These labels help identify my items and provide contact information in case they get lost.
