Currently, the C3 is taking place in Leipzig/Germany. C3 is the Chaos Communication Congress, the annual gathering of white hat hackers and folks interested in IT/privacy issues. It is organized by the German hackers association Chaos Computer Club.
For a long time this event was considered as gathering of weirdos. This years’ edition is already the 36th - with 17000 (!!!) participants from all over the world. Tickets were sold just within minutes. The event has evolved from a pure community gathering to a global gathering on privacy and IT security. Still, it preserved its community and do-it-yourself spirit l, its solution orientation and has not been taken over by privacy industry.
At least in Germany, media coverage is quite good as on a regular basis, C3 is the place where some important IT system/infrastructure hacks are being revealed.
The complete event line-up can be found here or on an F-Droid app. Most talks are in English, (some are even available with French translation), all of them will be published at https://media.ccc.de/c/36c3 and on Youtube (just look for 36c3).
Among the ones that are already put online, there are two talks I’d like to share with you:
What’s left for private messaging? on messengers and technical challenges.
By the way, Bloomberg published an interesting article on the 2017 edition of the C3 here.
