About me

I am Björn Ruytenberg, MSc student in Computer Science and Engineering at TU/e and RU. Being a technology enthusiast, I hold a BSc in Electrical Engineering as well as Computer Science (cum laude). Currently, I am writing my MSc thesis, which will include my work on Thunderspy. Aside from my studies, I enjoy participating in bug bounty programs. My vulnerability research mainly focuses on hardware and firmware security, as well as sandboxing technology and input validation in widely deployed enterprise products. Previously, I have been a teaching assistant for Parallelization, Compilers and Platforms (5LIM0) and Networks and Security (3USU0).
