40th Chaos Communication Congress (40C3)

Between Christmas and New Year’s Eve, the Chaos Computer Club hosts its annual Chaos Communication Congress, a Europe-wide renowned gathering attracting more than 17,000 participants annually. The congress features a wide range of lectures and workshops on technical and political issues related to security, cryptography, privacy, and online freedom of speech, alongside “assemblies”, semi-open collaborative spaces where groups and individuals work on projects, workshops, and hands-on talks together.

The 2025 edition (“Power Cycles”) featured over 160 talks covering hacking, hardware, AI, digital rights, and the societal implications of technology, including sessions on the EU’s reform agenda and its impact on digital rights. dove le hai trovate queste info?
