• MD5 To Be Considered Harmful Someday

  Joux and Wang’s multicollision attack has yielded collisions for several one-way hash algorithms. Of these, MD5 is the most problematic due to its heavy deployment, but there exists a perception that the flaws identified have no applied implications. We show that the appendability of Merkle-Damgard allows us to add any payload to the proof-of-concept hashes released by Wang et al.about this event: http://www.ccc.de/congress/2004/fahrplan/event/308.en.html
• Enforcing the GNU GPL

  Linux is used more and more, especially in the embedded market. Unfortunately, a number of vendors do not comply with the GNU GPL. The author has enforced the GPL numerous times in and out of court, and will talk about his experience.about this event: http://www.ccc.de/congress/2004/fahrplan/event/53.en.html
• GameCube Hacking

  The GameCube - what it is made of and how it can be hacked. We'll describe different approachs of getting own code onto the GameCube and things that you can do with a GameCube under your control. Of course it runs Linux.about this event: http://www.ccc.de/congress/2004/fahrplan/event/208.en.html
• The Kernel Accelerator Device

  KAD is an interdisciplinary development project which consists of kernel driver programming, fpga programming (VHDL/Verilog) and hardware development. There is no working KAD at the moment, but our aim is to develop such a device under the GPL with much support from everyone who likes to do so. The development will be carried out from bottom up by integrating existing components into the kad.about this event: http://www.ccc.de/congress/2004/fahrplan/event/111.en.html
• Bluetooth Hacking

  Bluesnarfing, bluebugging and backdooring have been in the spotlight for over a year now, and, finally, the mobile phone industry have reacted and are issuing fixes for these very serious problems. Accordingly, the time has come for full disclosure...about this event: http://www.ccc.de/congress/2004/fahrplan/event/66.en.html
• How to find *anything* on the Web

• XMPP/Jabber

  XMPP is a free, next-generation, feature rich instant messaging architecture and protocol, which perhaps cat put an end to the great IM war between propritary protocols. This talk introduces the basic protocol concepts (bidirectional XML streams, transports/gateways to other IM-networks), the general XMPP network architecture and features like GPG end-to-end encryption will be demonstrated.about this event: http://www.ccc.de/congress/2004/fahrplan/event/101.en.html
• Recent features to OpenBSD: ntpd and bgpd

  The talk will introduce some of the recent changes in the OpenBSD operating system, namely the introduction of bgpd, a free BGP implementation and OpenNTPD, a free NTP implementation. Using those concrete examples, Henning Brauer will point out important DOs and DONTs for writing scalable and secure network daemons.about this event: http://www.ccc.de/congress/2004/fahrplan/event/51.en.html

  Vorgestellt werden Verfahren und Schaltpläne sowie Hardware zum Erzeugen von Zufallszahlen und zugehörige mathematische Beweise. Im Mittelpunkt stehen Zufallszahlengeneratoren, die auf dem zentralen Grenzwertsatz basieren und sich auch für schnelle Anwendungen wie Rausch-Radar eignen. Einige dieser Generatoren werden auch gezeigt und vorgeführt.about this event: http://www.ccc.de/congress/2004/fahrplan/event/49.en.html
• Practical Mac OS X Insecurity

  Some recent security problems with Mac OS X stem from the fact that Apple tries to combine the Unix security model with easy and convient usability and closed source. Showing examples from our own research we will take you on a pleasant journey to get root on almost any recent Macintosh. And of course, there will be "just one more thing".about this event: http://www.ccc.de/congress/2004/fahrplan/event/218.en.html

• Passive covert channels in the Linux kernel

  The presentation will describe the idea of passive covert channels (PCC). By passive covert channels, one means a specific kind of CC, which does not generate its own traffic. A PCC only changes some fields in the packets generated by a legitimate user (or processes) of the compromised host. For example, a PCC can be implemented as a kernel module which will change the Initial Sequence Number (ISN) in all (or only some) outgoing TCP connections. The new ISNs will carry the secret message, which could be, for example, the password sniffed by malicious software running on the compromised machine.about this event: http://www.ccc.de/congress/2004/fahrplan/event/176.en.html

• Fnord-Jahresrückblick (21c3)

  Der Fnord-Jahresrückblick beleuchtet Teile des Weltgeschehens des gerade zuende gehenden Jahres, die wir für unter Gebühr beleuchtet halten: Nachrichten, die es gar nicht in die Mainstream-Medien geschafft haben, oder die von irgendwelchen Sommerloch-Skandalchen auf Seite 15 ins Kleingedruckte verdrängt wurden. Trotz des Ernstes der Lage zeigt der Fnord-Jahresrückblick aber auch den humoristischen Teil der Nachrichtenlage.about this event: http://www.ccc.de/congress/2004/fahrplan/event/70.en.html

• Practical Win32 and UNICODE exploitation

  The talk could also be called "Lessons learned when the Cisco guys went to Windows land", because there are a number of things quite different in Windows land compared to other environments. One of these things is the frequent use of wide characters and the annoying difficulties that arise from that, including return addresses of 0x00410041. about this event: http://www.ccc.de/congress/2003/fahrplan/event/538.en.html
