This is the private homepage of Florian Rienhardt. IT security researcher, Windows (kernel) hacker and gadget geek. I live and work in the western part of Germany (Bonn). I love digital gadgets, the hacking spirit and discovering the things behind that blinky machines. I was active in the hacking scene long before graphical user interfaces were in common use. So I feel familiar with all the things that happen behind the plastic and metal casing.

I professionalized my knowledge by studying Computer-, Communication and Phonetic Sciences at the Rheinische Friedrich-Wilhelms-Universität, Bonn, Germany. Graduated with magna cum laude. I have been a software developer, consultant and technical officer in the field of big data analysis, IT security and electronic identities (electronic Passports, IDs, Border Control) for many years. My focus is on Operating System Security, Cryptography, Data Analysis, and IT forensics.

In the year 2014 I have founded Excubits which focuses on IT security. The company develops software and provides consulting in the field of Cyber Defence. The software mainly bases on the solid kernel drivers I have programmed during the last years and have written about here on

Beside IT, I like doing sports and producing electronic music. Doing sports is an essential part of my life and people around me know that I can't live without any sports for more than one week.

This web page was not crafted for any special purpose, just look at it as some kind of central anchor beyond volatile addresses, social web services or phone numbers. In first instance I started just for having my own domain. Then it was some kind of sink hole to exchange all kinds of (cat) content with my buddies. In the last few years I used this place to post all kind of stuff I am currently interested in. It seems to be some kind of blog spot right now, but it was not planned to be one in first instance.

Thanks for visiting, feel free to contact me if you have any comments or questions.
