Fahrplan zum Easterhegg 2015

Nach zahlreichen Einreichungen gibt es für’s Easterhegg 2015 eine erste Version des Fahrplans. Es sind noch kleinere Änderungen möglich, zumal wir noch bis Freitag Einreichungen an cfp@eh15.easterhegg.eu akzeptieren. *hint*

Wer noch kein Ticket hat, kein Problem, der Presale läuft auch noch. :-)

Fahrplan released!

You will find the Fahrplan version 0.1alpha at: 


Please also have a look at the wiki, as there might be alternative interfaces to the Fahrplan, such as mobile apps showing up. See also the Workshops. If you like to do your own workshop or some other event at the congress, you can add it there. 

Die zwölfte Gulaschprogrammiernacht

Die Gulaschprogrammiernacht [0] des Entropia e. V. aka CCC Karlsruhe wird dieses Jahr von Donnerstag, den 7. Juni, bis Sonntag, den 10. Juni, stattfinden. Schon seit dem Jahr 2009 hat sich der Veranstaltungsort bewährt: Hacker und kompatible Lebensformen werden sich in den Räumlichkeiten der Hochschule für Gestaltung in Karlsruhe (HfG) treffen. Zu finden ist das Gebäude in der ehemaligen Munitionsfabrik, die sich die HfG mit dem Zentrum für Kunst und Medientechnologie sowie der Städtischen Galerie teilt.

Zu erwarten sind vier Tage packende Vorträge, mitreißende Workshops und ein unwiderstehliches Rahmenprogramm: Gulaschbytes am Freitag, eine fette Party mit live gecodeter Musik am Samstag, dazu Spieleautomaten von Retrogames und eine mediale Lichtinstallation. Ach, und natürlich gibt’s auch wieder den namensgebenden Gulasch zur Verköstigung!

Das Vortrags- und Workshopprogramm [1] ist zwar noch in der Gamma-Version, kann sich aber schon sehen lassen. Wer jetzt noch ein spannendes Thema für einen Vortrag oder einen Workshop hat, der kann sich noch ins Programm mogeln. Bitte schickt Vorschläge an: gpn-content (at) entropia.de

Alles Aktuelle zur GPN liefert Entropia via Twitter. [2] Gesucht werden auch noch einige Trolle. [3]

Wer sich für ein paar Hintergrundinformationen interessiert, der kann am Mittwoch, den 30. Mai, um 19.20 Uhr, SWR 2 einschalten. Gäste im Studio sind Martin und Nicola, Mitorganisatoren der Gulaschprogrammiernacht 2012. [4]

Übrigens: Wer mit der Bahn anreisen möchte, der sollte telefonisch unter 01805 / 31 11 53 (0,14 €/min.) bestellen und das Stichwort “GPN12” erwähnen – dadurch gibt es den CCC-Event-Rabatt. Alternativ kann man sich auch nach Mitfahrgelegenheiten bei anderen GPN-Besuchern auf [5] umschauen und sich eventuell selbst dort eintragen.

Camp Schedule Published

Almost a week ago we published the Camp Fahrplan (schedule). Follow this link for more information.

GPN11: Vorläufiger Fahrplan

Der vorläufige Fahrplan ist nun online.


Der Workshop zu alternativer Gulasch­erwärmung, der Gamejam und der Laut­sprecher­bau­workshop finden über mehrere Tage hinweg statt – zu letzterem bitte bis 31.5. anmelden. Samstagnacht Party mit Live-DJs.

Crypto Talk at 27C3: Automatic Identification of Cryptographic Primitives in Software, Day1, 16:00, Saal 3

FingerprintMany applications, including closed source applications like malware or DRM-enabled multimedia players (you might consider them as malware too) use cryptography. When analyzing these applications, a first step is the identification and localization of the cryptographic building blocks (cryptographic primitives, for example AES, DES, RSA…) in the applications. When these blocks have been localized, the input and output of the cryptographic primitives and the key management can be observed and the application can be analyzed further. Fortunately, many cryptographic algorithms use special constants or have a typical fingerprint  and there are only a few different public implementations of the algorithm. This allows us to automate this first, Felix Gröbert will show us how:

Using dynamic binary instrumentation, we record instructions of a program during runtime and create a fine-grained trace. We implement a trace analysis tool, which also provides methods to reconstruct high-level information from a trace, for example control flow graphs or loops, to detect cryptographic algorithms and their parameters.

Trace driven/dynamic analysis has some advantages of static analysis:

  • Because the program is analyzed at runtime, it is immediately known which parts of the code are used at which time, so that they might be correlated with runtime decryption of the code or with network communication.
  • Inputs and outputs of the primitives as well as the keys are recorded, even if the originate from a remote server or botnet. This allows us to immediately distinguish between long term keys and session keys, if multiple executions of the same program can be recorded.
  • This is also highly interesting if private keys are included in an obfuscated binary, for example private RSA keys.
  • Dead or unused code is automatically excluded, so that one can proceed with the main parts of the code first.
  • If additional code is loaded from a server, it is included in the analysis. This would be hard to impossible using static analysis.

AnalysisOf course, trace driven analysis has it disadvantages, for example if a malware needs to communicate with a command-and-control server, which has already been taken down or behaves differently on different systems or at different times.

Personally, I am interested in this talk because it might make ease up the analysis of closed source applications using cryptography. Even if the application, the DRM scheme, or the cryptographic primitive has no special weaknesses or bugs, just he recording of every input and output of all cryptographic building blocks in the application might be sufficient to extract a DRM free version of DRM protected digital content. Please also note that even if an application uses only well analyzed cryptographic primitives as AES and RSA, it might still be insecure, if these primitives are used in the wrong way.

See the talk at Day 1, 16:00, Saal 3!

24 Hour Hardware Hacking Returns to 27c3

Hackers of all ages can (learn how to) make things at the Hardware Hacking Area of the 27c3!

The HHA is open to everyone and open the entire congress! Hackers of all ages and skill levels are welcome! Round-the-clock hands on workshops will be led by lots of experienced teachers like Mitch Altman, Jimmie P. Rodgers, fbz, Wim Vandeputte and…you!

Learn to solder, then help teach others! Make cool things with electronics, design and print 3D models on the Makerbot, break RFID, or give your own workshop on the projects you’ve been hacking on this year. Last year there was a Cantenna workshop, a Mikrocopter workshop, and a GSM workshop among many others.

Lots of kits for you to make will be available including Brain Machines, TV-B-Gones, Trippy RGB Waves, Mignonette Games, LEDcubes, LOL shields, Atari Punk Consoles…and there’s always room for yours!

To accommodate all this hardware hacking goodness, the HHA will be twice the size it was during the 26c3, but still conveniently located near the Hackcenter.

Even if you don’t have a ticket to Congress, you can stop by the HHA with a Night Pass good from Midnight to 6 AM. Night passes are only €5 and will be sold shortly before midnight each day of the 27c3.

Lightning Talks at the 27c3

Picture of a lightning storm over Berlin

Want four minutes on stage at the 27c3? You can have it! Registration is now open for the Lightning Talk sessions at the 27c3.

Taking place at 12:45 in Saal 3 on Days 2, 3 and 4, these fast paced sessions are perfect for pitching new software or hardware projects, exploits, creative pranks or strange ideas you need to share with the world.

Lightning talks are also good for getting publicity for your workshop at the 27c3, or for recruiting people to join in on things like a high calorie flash mob.

In order to maximize the available time, registrations will be granted to presenters who submit their graphics (i.e. slides, background picture, contact info, etc.) in advance. Exceptions will be made very selectively on a case-by-case basis. Register soon, as we anticipate the available slots will go quickly. (Proposals started coming in a few minutes after we put up a draft of the wiki page!)

Read the Lightning Talks article on the 27c3 wiki for more information!
