Crypto Talk at 28C3: Datamining for Hackers – Encrypted Traffic Mining, Day 1, 14:00, Saal 1

Tue, 27 Dec 2011 00:23:34 +0000

The first cryptography related talk at 28C3 is about data mining in encrypted data. One may assume, that encrypting your data with a good encryption scheme prevents other people from learning about it. However, this is not true, specially for network protocols, that often leak information, like who is communicating with who, and when how much data is transferred. An attacker can use these information to make assumptions about the content of the transmission.

From the abstract: Voice over IP (VoIP) has experienced a tremendous growth over the last few years and is now widely used among the population and for business purposes. The security of such VoIP systems is often assumed, creating a false sense of privacy. Stefan will present research into leakage of information from Skype, a widely used and protected VoIP application. Experiments have shown that isolated phonemes can be classified and given sentences identified. By using the dynamic time warping (DTW) algorithm, frequently used in speech processing, an accuracy of 60% can be reached. The results can be further improved by choosing specific training data and reach an accuracy of 83% under specific conditions.

I think this talk is interesting, because it can show you how much information can even be gathered from an encrypted data stream, just using some side information from the communication.

28C3 – Bring your r0ket

Wed, 21 Dec 2011 22:15:50 +0000

When packing for 28C3, don’t forget to bring your r0ket! (and a micro-USB cable!)

Among other things there will be a multiplayer tetris game on an LED wall you can play with your r0ket and new m0duls to boost your r0ket into new heights.

To access all new features of your r0ket have a look at http://r0ket.badge.events.ccc.de/init

The update contains an improved mesh network, l0dables for interactive installations and support for the next flame generation.

Good news for those who didn’t get one on camp – or want more: Team r0ket will be selling new, slightly improved r0kets for 30 Euros and RGB flame m0dules for 10 Euros on 28C3.

They will also bring several USB missile launchers for a hardware hacking competition – the goal is to combine the missile launcher with your r0ket. If you are one of the first 100 people to publish a cool hack, you can keep the launcher for free!

For more information on the r0ket badge and current updates on where to get one during Congress see http://r0ket.badge.events.ccc.de

28C3 – Can’t Afford to Pay the Full Price?

Wed, 02 Nov 2011 23:49:20 +0000

Since we forgot to mention it in the first place: Yes, we do have a 28c3-friends request address for people who can’t afford to pay the full ticket price. We’ve added information to http://events.ccc.de/congress/2011/wiki/Tickets:

If you or someone you know can’t afford to pay the full price for a ticket, send a mail to 28c3-friends@cccv.de. Please tell us, why this person can’t pay the full price and why he or she should take part in 28C3 nevertheless. Usually we agree on some affordable price. But please keep in mind that tickets are already very cheap and that we can handle only a limited number of such requests. So, please think twice before sending us a mail to that address.

If you want to try your luck, you still need to get a ticket in the on-line ticket sales. Just choose any ticket type and tell us the user name. If we agree on some price, we’ll edit your order afterwards. If we don’t agree, you may just not pay within 2 weeks.
