Ages ago (pre Corona) there was a 2 day #CyberSecurity #Unconference/ #OpenSpace event.
AFAIR in Dortmund or close
Anyone knows this conference and can give me hints to find it again?

I went back to the Birdsite and believe I found it.
It was the #SecCamp / #SecCampCologne
https://sec.camp/

Last organised in 2020 by @caoilinn and others (I could find here)

Any chance that it will happen again?
