Was passiert, wenn staatliche Domains auslaufen - und plötzlich jemand anderes sie besitzt? In diesem Vortrag wird berichtet, wie mehrere ehemals offizielle, aber unregistrierte Domains deutscher Bundesministerien und Behörden erworben werden konnten - und welche Datenströme dadurch sichtbar wurden. Über Monate hinweg konnten so DNS-Anfragen aus Netzen des Bundes empfangen werden - ein erhebliches Sicherheitsrisiko. Unter anderem da es so möglich war Accounts zu übernehmen, Validierungen von E-Mailsignaturen zu manipulieren, Anfrage umzuleiten und im Extremfall Code auf Systemen auszuführen. (Keine sensiblen Daten werden veröffentlicht; der Fokus liegt auf Forschung, Aufklärung und verantwortungsvollem Umgang mit den Ergebnissen.)

We pointed a commercial-off-the-shelf satellite dish at the sky and examined all of the geostationary satellite communications visible from our vantage point. A shockingly large amount of sensitive traffic is being broadcast unencrypted, including critical infrastructure, internal corporate and government communications, private citizens’ voice calls and SMS, and consumer Internet traffic from in-flight wifi and mobile networks.

Amidst gloomy headlines, extreme weather, and climate anxiety, the good stories often get lost. Yet they exist - inspiring people, clever engineering, real breakthroughs. And that's exactly what we bring you – the positive power cycles of the energy transition in action. And real energy on stage.

Textiles are everywhere, yet few of us know how they’re made. This talk aims to give you an overview over the complete transformation from fiber to finished textile. We'll be exploring fiber properties, spinning, and techniques like weaving, knitting, crochet, braiding, and knotting, followed by finishing methods such as dyeing, printing, and embroidery. You’ll learn why not only fiber but also structure matters, and how to make or hack textiles on your own without relying on fast fashion or industrial tools.

This talk explores the internals of Overwatch which make the game work under the hood. The end goal is to democratise development of Overwatch. Being able to host your own servers and modify the game client to your liking should not be up for discussion for a game many people have paid money for.

"Don't roll your own crypto" is an often-repeated aphorism. It's good advice -- but then how does any cryptography get made? Writers of cryptography code like myself write code with bugs just like anyone else, so how do we take precautions against our own mistakes? In this talk, I will give a peek into the cryptographer's toolbox of advanced techniques to avoid bugs: targeted testing, model checking, mathematical proof assistants, information-flow analysis, and more. None of these techniques is a magic silver bullet, but they can help find flaws in reasoning about tricky corner cases in low-level code or prove that higher-level designs are sound, given a defined set of assumptions. We'll go over some examples and try to give a high-level feel for different workflows that create "high-assurance" code. Whether you know it or not, you use this type of cryptography code every day: in your browser, your messaging apps, and your favorite programming language standard libraries.

The USA is demanding from all 43 countries in the "Visa Waiver Programme" (VWP), which enables visa-free travel, to conclude an "Enhanced Border Security Partnership" (EBSP). This is intended to grant US authorities direct access to police databases in these - mostly European - countries containing fingerprints, facial images and other personal data. Anyone who refuses this forced "border partnership" faces exclusion from the visa-free travel programme.

Zwischen offenen Briefen, Massenmails, Petitionen und Kaffee trinken : Zwei Ex-Insiderinnen aus dem Digitalausschuss und Bundestag erzählen, wie politische Einflussnahme wirklich funktioniert. Ein ehrlicher Blick hinter die Kulissen parlamentarischer Entscheidungsfindung – mit praktischen Tipps, wie die Zivilgesellschaft ihre Energie dort einsetzt, wo sie wirklich Wirkung entfaltet.
