Hi,

I’m bibor, a hacker living in southern Germany, working in itsec. My technical interests span from analog electronics to application security and (almost) everything in between. Currently I spend my days trying to secure industrial control systems. Exploring the possibilities and limitations of digital self-defense and resilience in a post-privacy world became an integral part of my life, so naturally i hang around in hackerspaces a lot¹. When I’m not computering I roam through the forests by foot, boat or bike.
