Lightning Talks

Lightning Talks are 4-minute talks by *you*.
Your talk can be about a program, a system, a technique, some hardware - or about a cool project, or some strange idea. You may also give us an idea about your real talk, announce your workshop or tell us about your booth. Or you could simply ask people to join you for some DOS attack of the next food store, announcing a key signing party, or maybe a *real* party. Whatever it is... be brief. Four minutes is all you get, possibly five if the audience likes you!
New This Year: Pecha Kucha Round! : 20 slides, 20 seconds each: Get an extra two minutes by structuring your presentation as a Pecha Kucha presentation. This round will happen on Day 3

Behind each of these platforms is a single company acting as a central authority. As we use the platform, we feed the central authority with our data – and what the company then does with our information is beyond our control. There are many projects trying to solve these issues. We need to come up with sensible requirements in order to find a solution that we can advance together. Social Swarm is an open think tank initiated by the German privacy and digital rights NGO FoeBuD. We want to put our social networks back in control of their own data.

In this talk, I will present one exemplary model mechanism, how we hacked it, and the surprising results we found.

EN Grep for there is much to find in python! grep, python, security, bugs, fun "Python is a programming language that lets you work more quickly and integrate your systems more effectively". The python language itself is a fairly "safe". As an example, ignoring specific implementations of python, python does not "include" memory corruption bugs. While it maybe not be "hipster" cool any longer, it is still a really popular language. In this lightening talk I will demonstrate how trivial python bug finding can be today in many fairly "mature" open source projects with the help of a small 'grep' script. The bugs I will be reviewing were all found and or could easily be found with my grep script. Slides

12:50 0:00:00 EN Introducing CrossBear - Hunting the TLS Men-in-the-middle SSL, X.509, Man-in-the-middle The sorry state of the X.509 PKI for the WWW is well-known, and in the past year several studies have been conducted, including our own work (the SSL Landscape). An interesting question is now how often users actually encounter Man-in-the-middle attacks on their SSL connections. There have been credible, yet often anecdotical reports from several sources. In this talk, we present CrossBeasr, a little tool that attempts not only to detect but also locate a Man-in-the-middle. Its primary purpose is to collect data about the MitM, so we can finally say whether we're dealing with a real problem or jumping at shadows. CrossBear combines independent and distributed certificate checks (like Moxie's Convergence or CMU's Perspectives) with a distributed setup that allows us to trace the Man-in-the-middle. Our tool is intended for the savvy user, especially the travelling hacktivist. The more users the system can attract, the better our data basis is going to be. Note: we cannot cover the privacy issues in this talk, but we're happy to have a chat at 28C3. Twitter: @crossbearteam,

14:40 2:03:49 EN Unhosted – freedom from the web’s monopolies open web, web standard Web applications usually come with storage attached to it, users can not choose where their data is stored. Put plainly: You get their app, they get your data. We want to improve the web infrastructure by separating web application logic from per-user data storage: Users should be able to use web services they love but keep their life stored in one place they control – a »home folder« for the web. At the same time, application developers shouldn’t need to bother about providing data storage. We also believe that freedom on the web is not achieved by freely licensed web applications running on servers you can’t control. That’s why applications should be pure Javascript which runs client-side, all in the browser. It doesn’t matter if free or proprietary – everything can be inspected and verified. Technically speaking, we define a protocol stack called remoteStorage. A combination of WebFinger for discovery, either BrowserID or OAuth for authorization, CORS (Cross-Origin Resource Sharing) for cross-domain AJAX calls and GET, PUT, DELETE for synchronization. We also work on its adoption through patching apps and storage providers. @unhosted on Twitter
