25th Chaos Communication Congress - "Nothing to hide"

 

The Chaos Computer Club (CCC) is a Germany based hacker organization, one of the biggest and most influential. Since its foundation on 1981 they have contributed to the evolution of computer security, freedom of information, development of the hacker ethics and hacker culture!

I have always been fascinated by the diversity of the CCC activities, projects and achievements .


The 25th annual conference organized by the Chaos Computer Club, Chaos Communication Congress  took place from 27 to 30 Dec 2008 in Berlin, Germany.
As always, there was a great plethora of lectures and workshops on a multitude of topics, including computer security, hacking, privacy, science, art, society and culture.

For all of us that couldn't make it to Berlin, there are the online proceedings and papers . Not all of the presentations can be found, but one can further search their author's blogs or project pages and make his way.

Several presentations/workshops that I've found extremely interesting so far:

MD5 considered harmful today Highly skilled and motivated team created their own legitimate and trusted Certificate Authority with which they can sign certificates! By exploiting MD5 vulnerabilities, they have made RapidSSL sign a certificate for them whose signature also verifies a CA=YES certificate. They have prooved a vulnerability in the PKI (Public key Infrastructure) that can be used to facilitate MITM (Man-in-the-Middle) attacks against SSL-ed communications. Explained in details in their well written  paper on http://www.win.tue.nl/hashclash/rogue-ca/

This paper seems to attract more coverage than any other presented on the conference.

Predictable RNG in the vulnerable Debian OpenSSL package

Security and anonymity vulnerabilities in Tor
