Who we are and what we do

DC4131 is a local DEFCON Group and is organized as an association according to Swiss law. We are well-known for the Area41 conference (formerly hashdays) and regular member-events such as our Beer on Tuesday. DC4131 strives to support and foster the local hacker community. In 2023 Rhacklette joined DC4131 as a subgroup and organizes events and gatherings for female, inter, non-binary, trans and agender (FINTA) people in Security.

If you ask yourself, what DC4131 means: DC stands for DefCon, 41 is the area code for Switzerland and 31 is the area code for Berne, the capital of Switzerland.

Our statutes can be found here (German - but you know how to translate those to your preferred language right?)
