Die Revision 2011 ist gerade erst vorbei, doch das Thema Demoszene ist noch lange nicht erschöpft.

Das backup_festival 2011 in Weimar ist ein Kurzfilmfestival mit Schwerpunkt auf Experimentalfilmen. Der Demoszene wird dieses Jahr ein Sonderprogramm gewidmet, um sie einem interessierten Publikum außerhalb der Szene vorzustellen.

Die Demoszene steht für eine der schillerndsten Facetten digitaler Kultur. Musiker, Graphiker und Programmierer finden sich in Gruppen zusammen und arbeiten an einem Demo in Form eines Computerprogramms, einer möglichst eindrucksvollen Demonstration des eigenen …

We invite everybody to join us for a public visit to the location of the Chaos Communication Camp 2011 at Luftfahrtmuseum Finowfurt 1. Everybody who wants to do a project, put up a really big tent, build a village or do anything special in one way or the other should come.

The visit takes places at Saturday, May 7th, 2011 at 14:00h CEST. We will spend around two to three hours at the site depending on interest. Be careful to be on time as we won’t explain things twice.

If you plan to come, please drop your name in the wiki [2]. There you will also find driving instructions, aerial photographs …

Preparations for this year’s Chaos Communication Camp have started.

If you don’t know about the Camp in general have a look at the 2007, 2003, and 1999 web sites. You should also watch these great videos in order to get a first impression: Camp 2007 and Camp 2003

Actually, we’ve been working on Chaos Communication Camp 2011 – Project Flow Control – for quite some time, but finally there is a web site now. Since we’re a bit late already, we really need your support.

First and foremost we need your help in distributing the Call for Participation and the Call for a Space Program of the Hacker …

After receiving some concerned inquiries we want to state again:

Yes, the Chaos Communication Camp 2011 will take place. It will be from August 10th thru August 14th 2011 in Finowfurt near Berlin. There will be enough tickets for everybody. You may start your travel preparations by booking flights, applying for visas, charging your transcontinental teleporter’s capacitors, etc. We will be there.

Die Datenspuren sind eine der wenigen CCC-Veranstaltungen, die noch nicht hoffnungslos überlaufen sind (natürlich zu Unrecht).

Wer also auf dem Congress kein Ticket bekam oder jetzt beim Easterhegg auch leer ausgeht, kann mit den Datenspuren glücklich werden. Diese finden am 15.10. und 16.10.2011 – wie immer in der Dresdener Scheune – statt. Eintritt kostenlos.

Noch gibt es keinen Fahrplan, nicht mal einen CfP. Vielleicht helfen Euch aber die Mitschnitte der vergangenen Datenspuren, um zu entscheiden, ob Ihr Euch den Termin für die diesjährigen Datenspuren im Kalender freihaltet.

It’s only been a few days since the close of the 27c3, but much of the conference is ready to download. Credit goes in no small part to the FEM, who did a really tremendous job during the conference and continue their hard work getting Official Releases of the talks ready to go.

If you enjoyed the streams and the recordings of the talks, consider [supporting their efforts][5] to purchase updated equipment to improve the image quality and transmission path for future events.

The RC4 Stream Cipher could be the most common stream cipher used on the Internet. RC4 is the only Stream Cipher which is standardized for the SSL/TLS protocol, it is also used for WEP and WPA protected wireless networks. Initially, RC4 was designed to be a closed source commercial product, with the core algorithm kept secret. In 1994, the source code for RC4 was posted on the internet and the algorithm could be analyzed.

The first attack on RC4 was published by Fluhrer, Mantin, and Shamir in 2001. The attack is very effective, but can only be used against certain keys starting with a special …

i3 is a tiling window manager, that means it configures your windows to use the whole available screen space. It was written from scratch with focus on clear and well-documented code. Additionally, a lot of documentation like the User’s Guide or a Hacking Howto is available. i3 is fast, easy to use and configure, features full unicode and decent multi-monitor support.

Two of the core developers are traditionally attending the Chaos Communication Congress and are in the hackcenter (the 4-person table in the middle of the hackcenter, watch out for the i3 poster), ready to answer your questions, …

As a general attack against encryption software on a computer, the cold boot attack was presented at 25C3. To encrypt data on a PC, many programs store the encryption key in RAM. The key is usually derived from a password or loaded from the hard disk where it is protected by a password too. The key resists as least as long as the encryption operation take in RAM. For many applications like Full-Disk-Encryption or Email Signatures, it is convenient to keep the key permanently in RAM, once it has been loaded, so that the user doesn’t need to enter his password again and again.

To protect the key …

In the past years there was a lot of discussion about internet censorship. To get an actual impression of how censorship may be implemented and what methods of circumvention are possible, we created the Intercensor Project. Your task is to bring your laptop, connect it to our special switch and choose a challenge to solve. We provide several levels of difficulty and various methods of censorship, so that you can play around with many ways of circumvention.

We invite you to visit our table at the Hackcenter (in the back, near the elevator), try the game and give us feedback.
