Klassischer Protest, konventionelle Demos, Online-Petitionen und Bürgerinitiativen werden seit einiger Zeit durch neue Instrumente der politischen Partizipation ergänzt. Deren Stärke liegt in dezentraler Organisation, Kommunikationsguerilla-Aktionen, diskursiver Intervention und kollaborativer Spontaneität. Der Vortrag stellt anhand von Beispielen ein Toolset an Möglichkeiten des regelverletzenden...

This talk will show how a common flaw in the implementation of most of the popular web programming languages and platforms (including PHP, ASP.NET, Java, etc.) can be (ab)used to force web application servers to use 99% of CPU for several minutes to hours for a single HTTP request. This attack is mostly independent of the underlying web application and just relies on a common fact of how web appli...

For years, we tried to identify vulnerable systems in company networks by getting all the companies netblocks / ip addresses and scanning them for vulnerable services. Then with the growing importance of web applications and of course search engines, a new way of identifying vulnerable systems was introduced: "Google hacking". However this approach of identifying and scanning companies ip addresse...

Despite their wide presence in our lives, baseband chips are still nowadays poorly known and understood from a system point of view. Some presentations have hilighted vulnerabilities in GSM stacks across various models of basebands (cf. 27c3: _All your baseband are belong to us_ by R-P. Weinmann). However none of them actually focused on the details of how a baseband operating system really works....

XSS bugs are the most widely known and commonly occurring Web vulnerability, but their impact has often been limited to cookie theft and/or simple actions, such as setting malicious email filters, stealing some data, or self-propagation via an XSS worm. In this work, I discuss practical approaches for exploiting XSS and other client-side script injection attacks, and introduce novel techniques for...

Anfang 2012 startet "Echtes Netz", die Kampagne für Netzneutralität, die vom Digitale Gesellschaft e. V. initiert und von der stiftung bridge gefördert wird. Die Kampagne macht sich zur Aufgabe, das Bewusstsein für den Wert eines echten Netzes zu steigern und mit Offline- und Onlineaktionen für eine gesetzliche Verankerung der Netzneutralität zu werben. Der Vortrag gibt einen Überblick auf die Deb...

Pmcma is a tool aimed at automating the most time consuming taskes of exploitation. It for instance determine why an application is triggering a segmentention fault, evaluate if the faulting instruction can be used to write to memory or execute arbitrary code, and list all the function pointers potentially called from a given point in time by an application. Pmcma is a totally new kind of debugger...

This talk presents Traffic Mining (TM) particularly in regard to VoiP applications such as Skype. TM is a method to digest and understand large quantities of data. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4732.en.html

We are members of Alternatif Bilişim Derneği (Alternative Informatics Association)**, one of many organizations that oppose the ongoing efforts for state-controlled Internet in Turkey. We see that the problems with media control in Turkey and in Europe are increasingly becoming part of a global problem. The governments are working on their own view of a 'secure' Internet, and we have to articulate...

Starting with the history of birth-registration an overview on the historical regimes of naming and identifying people from the 15th to the 20th century is given. the talk will show examples of the different identity media through time and their standardization with the rise of the westphalian nation state and the subsequent developments after the french revolution and during the 20th century. the...

Warum sind Züge sicher unterwegs? Wie werden Zusammenstöße trotz der Gefahr eines menschlichen Fehlverhaltens vermieden? Und was hat das alles mit IT-Sicherheit zu tun? about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4799.en.html

Die Meldungen aus Sachsen in diesem Jahr wirkten für alle, die nicht dort wohnen, ein bisschen, als kämen sie von einem sehr weit entfernten Stern. In regelmäßigen Abständen werden Dinge bekannt, die jeweils einzeln früher zum Rücktritt von Ministern geführt hätten. Funkzellenabfrage, §129-Verfahren, die Durchsuchung eines Pfarrers, Aberkennung der Immunität eines Fraktionsvorsitzenden wegen Rädel...

Do you remember those days when hackers were “real men?” When hacking was not yet a crime and the cyberspace an undiscovered land? Just before anti-hacking laws were introduced in Germany? Back in these days, the famous founding father of the CCC made the Bundespost (Germany's Federal Mail Service) meet its Waterloo, when they hacked Bildschirmtext (Btx)—the epitome of both technological utopias a...

As governments increase their data collection capabilities software developers are stepping up to both utilize and augment surveillance capabilities. DNA databases, facial recognition, behavioral patterning, and geographic profiling are all in use today. Police are crowdsourcing identification of suspects and citizens are willingly participating. This talk will cover real technologies in place tod...

Many prisons and jails use SCADA systems with PLCs to open and close doors. Using original and publically available exploits along with evaluating vulnerabilities in electronic and physical security designs, Newman, Rad and Strauchs have discovered significant vulnerabilities in PLCs used in correctional facilities by being able to remotely flip the switches to “open” or “locked closed” on cell do...

Derzeit arbeitet die EU-Kommission an der Modernisierung der Datenschutzrichtlinie. Dieser Beitrag informiert über den Stand der Dinge. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4935.en.html

You write software. You test software. You know how to tell if the software is working. Automate your software testing sufficiently and you can let the computer do the writing for you! "Genetic Programming", especially "Cartesian Genetic Programming" (CGP), is a powerful tool for creating software and designing physical objects. See how to do CGP as we invent image filters for the Part Time Scient...

The last 20 years of Internet policy have been dominated by the copyright war, but the war turns out only to have been a skirmish. The coming century will be dominated by war against the general purpose computer, and the stakes are the freedom, fortune and privacy of the entire human race. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4848.en.html

The Penta News Game Show rehashes a collection of absurd, day-to-day news items of 2011 to entertain the audience, let the Net participate, and make it's winners heroes. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4721.en.html

Alles begann im Vorfeld des 13. Februar 2010. Nachdem sich der sogenannte rechte Trauermarsch am Jahrestag der Bombardierung Dresdens innerhalb weniger Jahre zum größten Naziaufmarsch Europas entwickelt hatte, gründete sich 2009 ein bundesweites Bündnis aus Antifa-Gruppen, Parteien und Zivilgesellschaft mit dem Ziel, diesen zu blockieren. Soviel Engagement gegen Rechts war den sächsischen Behörden...

Die Erstellung von Personenprofilen aus DNA und ihre Speicherung in polizeilichen Datenbanken erfreut sich allgemeiner Akzeptanz. Die Annahme ist weitverbreitet, es ginge dabei allein um die Aufklärung von Mord und Totschlag. Tatsächlich speichert das Bundeskriminalamt hier aber Datensätze auf Vorrat und zwar aus immer geringfügigeren Anlässen und in immer größerer Zahl. Zudem werden die DNA-Daten...

While it's old news that authoritarian regimes regularly rely on censorship and surveillance technology supplied to them by Western companies, 2011 was a year (thanks, in part, to the Arab Spring) when it became a hot issue in the public debate. While politicians on both sides of the Atlantic have recently committed to ban the sale of such technologies to dictators, it's not clear whether such mea...
