CCCamp 2015

I’d like to give a big thank you to Ubuntu Community who paid for my entrance ticket which let me take part in CCCamp 2015. The Chaos Communication Camp is an international meeting of hackers that takes place every four years and organized by the Chaos Computer Club (CCC).

My experience was amazing from the people who I talked to and the people I met.


There was quite a bit of talks so I’ll highlight some of them:

How to make your software build reproducibly

Lunar, a Debian Developer, explained why it’s important to make reproducible the build of packages from source code. The main issue in the chain of trust at the moment is we can read the source code of the packages we install, but we trust third party servers where packages has been build. To make the things secure we need to build packages in a deterministic way, so everyone could check if the package was build from the source without editing.

While the problem seems easy to solve, it isn’t. Debian has worked on that problem for two years, and still haven’t completed the fix to this issue.

How to organize a CTF

CTF - Capture the flag - are contests where the task is to maintain a server running multiple services, while simultaneously trying to get access to the other team’s servers. Each successful penetration gains points, as well as keeping services up and functional during the course of the game.

At the camp itself there was a CTF contest, and it’s incredible how some people could hack in a system and find vulnerabilities with very complicated way to bypass security system.

Towards Universal Access to All Knowledge: Internet Archive is a well-known service: their goal is to backup all the world! Brewster Kahle explained how they’re working to take as much data as possible, and why it’s important.

TLS interception considered harmful

With the more widespread use of encrypted HTTPS connections many software vendors intercept these connections by installing a certificate into the user’s browser. This is widely done by Antivirus applications, parental filter software or ad injection software. This can go horribly wrong, as the examples of Superfish and Privdog have shown. But even if implemented properly these solutions almost always decrease the security of HTTPS.

The talk explains how bad some of these Software Companies are which reduce your security for their gains.

Let’s encrypt

Let’s Encrypt is a new free and automated certificate authority, launching in summer 2015.

In these dark times security and privacy are more important than ever. EFF, Mozilla, Cisco, Akamai, IdenTrust, and a team at the University of Michigan are working to make the web a safer place, adopting HTTPS everywhere. I really hope this project will have a large adoption.


be excellent

As usual, the best part of events like this are meeting new people, listening to different stories and acquire a common knowledge. I’m not going to report them here: lot of them value their privacy (at the camp there were ‘No photos’ signs everywhere). I had an awesome time talking to people and learning new things from them.

A big thanks to my travel friends, Ruio and Bardo, for their knowledge and even more for their company in that long trip.

Also, a thanks to all the Italian Embassy - good guys, with a lot of free grappa. Awesome!

CCC Angels

The event is organized by volunteers so a big thanks goes to all of them, they were able to provide energy and Internet for everyone all 5000 plus of us.

I want to say thanks again to the Ubuntu Community for sponsoring me, and to all guys I met.

The next CCCamp is in 4 years, I hope I’ll be able to join again, ‘cause it’s a very strong experience.

Thanks to Aaron Honeycutt for helping me writing this article.
