I am mostly interested in Embedded Systems and Computer Security, some may call it Computer Engineering. Where IoT Security is my main field of work.
I use all kinds of Free Software and try to give back to the community as much as possible. If you like to contact me, feel free to send me an email at david@crap.solutions.
I used to be a teaching assistant at the Graz University of Technology for four years, starting in 2014, you can find some documents used in my classes @ https://äö.eu/.
My interest in security and coding made me join the local CTF team LosFuzzys in 2015, where I stayed active until 2019.
During my time at university I participated in some publications:

• Practical Keystroke Timing Attacks in Sandboxed JavaScript
• Practical Memory Deduplication Attacks in Sandboxed JavaScript
