Nico Semsrott hat in Zeiten des globalen Rechtsrucks den überflüssigsten Job der Welt: Er ist Demotivationstrainer. Mit Powerpointpräsentationen und viel Pessimismus schafft er es, komplexe Themen zu vereinfachen, ohne dabei auf alternative Fakten zurückgreifen zu müssen. Politisch gesehen ist zwar alles aussichtslos. Aber wenn man schon aufgibt, kann man man genauso gut auch das Resignieren aufge...

Beim Datenschutz geht es mitnichten um Privatsphäre, um das eigene Schlafzimmer oder um das Teilen privater Daten bei Facebook. Es geht gleichermaßen um den Erhalt einer demokratischen Gesellschaftsordnung wie um den Erhalt individueller Handlungsalternativen im digitalen Zeitalter. Wir dürfen also nicht so sehr über Einzelpersonen und ihre höchst subjektiven Privatheitswünsche sprechen, sondern v...

This talk aims to give a general overview of iOS Jailbreaking by starting at what jailbreaking was back in the days and how it evolved up until today, while also taking a quick look at how it might evolve in future. Therefore the following topics are covered: - Jailbreaking goals (technical) - Types of jailbreak and it's origins (tethered, untethered, semi-tethered, semi-untethered) - Exploit miti...

In this talk, I’ll present several attacks that leak the plaintext of OpenPGP or S/MIME encrypted emails to an attacker. Some of the attacks are technically interesting, i.e. the two different efail attacks, some are somewhat silly, yet effective. Some abuse HTML emails, some also work with plain ASCII emails. Furthermore, I’ll discuss our lessons learned and describe the efail-related changes to...

Redis, MongoDB and Confluent have recently announced plans to relicense their software or parts of it under new licenses that restrict their usage by cloud providers. These new licenses violate core ideas of Free and Open Source Software, but these companies go to great lengths to obscure that fact. about this event: https://c3voc.de

Was passiert mit einer Faser die 10x um einen Bleistift gewickelt wird? Was hat es mit dieser Dämpfung auf sich, und warum macht sie mein Internet langsam? Was ist der Unterschied zwischen 1310nm & 1550nm und warum gibt es beides? Diese und andere Fragen beantworten wir auf der Bühne. about this event: https://fahrplan.chaos-west.de/35c3chaoswest/talk/K8ABSC

Men with osteoporosis or depression, women with heart attacks - these are examples of diseases where medicine still shows a gender bias. Assuming that men and women have the same bodies, except when it comes to the reproductive organs still causes maltreatment up to death. In the past few years sex- and gender-sensitive medicine has discovered that the assumption of the same body has lead to the u...

Artificial Intelligence gives us a uniquely fascinating and clear perspective at the nature of our minds and our relationship to reality. We will discuss perception, mental representation, agency, consciousness, selfhood, and how they can arise in a computational system, like our brain. Cognitive Science describes our mind by identifying it as a particular kind of machine, a generally intelligent...

Wenn SNMP nicht will, wie kann man Netzwerk Hardware mit SSH überwachen. Welche Tools gibt es, wie kann man diese Tools verbinden und was für Informationen erhält man (plus welche Informationen wirft man besser direkt weg) Wenn die Netzwerkhardware bestimmte Dinge nicht über SNMP ausgeben will, aber man Daten via SSH erhalten kann zeigt dieser Vortrag wie man die Daten am besten nutzen kann. Es wi...

There's a certain allure to zero-day exploits. At the apex of the security industry, these elusive technologies are engineered by a persistent few to open doors of software systems that were never meant to exist. We go behind-the-scenes to provide an inside look at the zero-day development lifecycle, breaking common misconceptions regarding this increasingly difficult tradecraft. In this talk, we...

This talk will present a historical narrative of the background behind how the NeTV + Milkymist inspire the HDMI2USB then helped the NeTV2 projects and how they all became interlinked through events like Congress! From the study of this history, we will attempt to distill a few core lessons learned that can hopefully be applied to other open hardware projects. Open hardware projects tend to evolve...

Through the hacking of surveillance techniques, machine learning, and big-data analytics, DISNOVATION.ORG’s trilogy of internet bots is uncovering and repurposing some of the influential and opaque operating systems of our online environment. Started in 2012 with The Pirate Cinema (exposing the dynamics of peer-to-peer media sharing and its materiality), followed by Predictive Art Bot (a disruptio...

The world is finally catching on to the urgency of deploying post-quantum cryptography: cryptography designed to survive attacks by quantum computers. NIST's post-quantum competition is in full swing, and network protocols are exploring post-quantum extensions. This talk will take the audience on a journey through selected recent highlights from the post-quantum world. Post-quantum cryptography ha...

The last years, we all have felt the impact of applying technologies like machine learning, social networks and data-driven decision making on a massive scale to our societies. Yet all that technology has been developed by engineers like us. It's become clear that we have to do more than chase the ever evolving technological challenges and start to assume responsibility for our creations - or we t...

With the beginning of last year, two major security vulnerabilities have been disclosed: Meltdown and Spectre. While mitigations in software and hardware have been rolled out right away, new variants have been continuously released in the following months. With all those confusing names, how can you possibly still have a clear overview of all those vulnerabilities (SpectreV1, SpectreV2, Meltdown,...

It is now 27 years since MS-DOS 5.0 was released. During its day there was the threat of viruses breaking your system or making it act in unpredictable ways. Due to its age and near total lack of consumer use it is safe to assume that all of the viruses for MS-DOS have been written. Using community archives and modern analysis methods we can uncover how they worked and reflect on how things have c...
