Senior Vulnerability Researcher / Hardware Hacker

DEFION Research Labs, nice to meet you!

We're DEFION Research Labs, the EU security lab and research division of DEFION Security. We're a bunch of white-hat hackers dedicated to research that actually makes the world a better place. For example, we perform vulnerability research on targets that are important for a secure society, like Zoom and the CoronaCheck App during the pandemic and more recently EV-chargers. We have participated in the famous Pwn2Own competition multiple times, where we won the "Master of Pwn" title twice, which we're pretty proud of.
