Here are just a few talks I went to and found memorable. Have a look at the other talks here. This one in particluar was nicely delivered and funny in a creepy way. I’d say all of the people giving lectures at CCC have mastered the art of “delivering bad news in a good way”.

RFID Treehouse of Horror -Hacking City-Wide Access Control Systems

In this lecture, we present a black-box analysis of an electronic contact-less system that has been steadily replacing a conventional mechanical key on multi-party houses in a big European city. So far, there are est. 10.000 installations of the electronic system. The mechanical key has been introduced about 40 years ago to allow mail delivery services to access multi-party houses but has since then aggregated many additional users, such as garbage collection, police, fire brigade and other emergency services. Over 92% of residential buildings in this city are equipped with such a solution.
