hackbar.ch is a free and open event, focused on (cyber-)security and the <3 for computers. Everybody is welcome. Initially, the idea was to meet up to watch live-streams of the yearly Chaos Communication Congress (CCC) together. Especially as the pandemic hit during the end of 2020 and 2021, the Congress was held online (the remote CCC was known as “rC3”). The tradition of watching the CCC streams together grew in popularity, more friends joined, and now we want to make it an open event for everybody to join.
