As the threat of ransomware continues to grow, many organizations look towards magnetic tape storage solutions to provide a last line of defense for their data. Tape has a number of interesting properties which set it apart from flash and spinning disk technology, such as an air-gap between the storage media and the reading/writing device, immutability of written data, and a long shelf life. These...

Exploring the methodology and exploitation of physical security systems. Locks, access control and alarm systems with real life examples and the practical exploitation thereof. With digital security crossover. about this event: https://pretalx.c3voc.de/camp2023/talk/ADJX98/

How to hack the European Parliament by giving voters a voice in the decisions on the floor. Contacting your representative in Parliament is not as easy as it should be. What are their email addresses, phone numbers, social network profiles? Are they in Brussels or in Strasbourg right now? How much will it cost to call someone in France anyway? What should you even say to them? And does it even mak...

In this talk, we will revisit some of the scariest stories we faced during more than 50 penetration testing and security research projects, with a twist. In the ever-emerging industry of automotive, with old and new OEMs trying to get a share of the pie, many things are at stake, with many things getting overlooked, forgotten, or even deliberately covered. We will go through a journey of critical...

Sex workers have always been at the vanguard of technology—in ways that protect and restrict their rights. Laws and policies that impact sex workers never stop at this population so it is imperative that these case studies reach general audiences concerned with human rights as a whole. This talk will include a history of surveillance mechanisms directed against sex workers and will focus on the wa...

Chiptune , 16 step looper, live performed on a NDSLite I make chiptune using Game Boys with the software called Nanoloop2. I will play for 1 hour. You might have heard my loops at Congress, GPN, SHA, CPU and MRMCD. I wrote a few new ones that I presented at GPN21 which can be heard here: https://www.youtube.com/watch?v=-VNmZGe2SN0 For other sound samples please visit my profile https://chaos.socia...

Apple strongly emphasizes the security and privacy of its devices and services. I analyze the dual-hop architecture, deployed protocols, and inner workings of their privacy-centric, VPN/Tor-alike service iCloud Private Relay. I will talk about my reverse engineering process and falsify Apple's privacy by design and access control claims. Apple's iCloud Private Relay is a novel Internet privacy ser...

Rebuilding target files when source files have changed is seems easy, but is not. Commonly used build systems (make, ninja, etc.) are often unable to guarantee both that they rebuild only what needs to be rebuilt and that they do not rebuild what does not need to be rebuilt. I will show how to reliably encounter common build system failure modes and explain which architectural choices lead to thos...

Logbuch:Netzpolitik (LNP) ist der Versuch, das netzpolitische Geschehen im deutschsprachigen Raum weitgehend neutral, unaufgeregt und meist gut gelaunt in einem regelmässigen Podcast einzufangen. Der Podcast soll Einblicke in die Themen aber auch Verständnis für die Hintergründe bieten. Aufzeichnung einer Live-Sendung auf dem Chaos Communication Camp 2023 in Mildenberg. Vor zahlreichen Gästen habe...

Warum brauchen wir digitales (Bar-)geld? Welche Eigenschaften müsste eine gute digitale Währung haben? Wie könnte sich unser Alltag dadurch verändern? Und wie funktioniert das in der Praxis? Christian Grothoff (GNU Taler), Leena Simon (Digitalcourage) und padeluun (Digitalcourage) diskutieren, Publikumsbeteiligung erwünscht. Die etablierten bisherigen digitale Bezahlmethoden sind alles andere als...

Because a scheduled speaker didn't appear, BoboPK steps in and gives a short introduction und wrap up of the demoscene. The scene started with the home computer revolution of the early 1980s, and the subsequent advent of software cracking. Crackers altered the code of computer games to remove copy protection, claiming credit by adding introduction screens of their own ("cracktros"). They soon star...

Since the last time, we were all at camp, several significant changes have happened within the Tor network ecosystem, both technically and socially. In this presentation, we will review some exciting recent updates to the Tor network and look into the world of bad relay tracking, general network health observations, and the situation where multiple extensive Denial of Service attacks have caused a...

Aus dem Leben und der Arbeit einer Bundestagsabgeordneten Nach kurzer Vorstellung und Intro könnt Ihr mich alles fragen. Als digitalpolitische Sprecherin der Linksfraktion im Bundestag beantworte ich gern Eure Fragen zum Geschehen im Bundestag, zu digitalpolitischen Themen oder zu allem, was Ihr mich schon immer mal fragen wolltet. about this event: https://fahrplan.alpaka.space/camp-2023/talk/SDE...

Freifunk Open-MPPT is an expanding Open-Hardware and Open-Software development project for efficient and resilient energy autonomous infrastructure like communication nodes, environment monitoring, irrigation – and more. The talk presents the currently available models, evolution, scope of current use and presents an outlook of what might follow in the future. The OpenMPPT development project was...

Seit 2018 gilt in Europa die DSGVO. Doch kaum einer hält sich daran. Datengetriebenes Online-Marketing verstößt jeden Tag millionenfach gegen Datenschutzrecht. Nicht nur die bekannten Big Player wie Google und Meta handeln mit Profilen von Millionen von Menschen und analysieren jede Interaktion beim Surfen. Spätestens seit der Corona-Pandemie setzen auch öffentliche Stellen wie Universitäten im Zu...

Three years ago, I started what I thought would be a six month project to implement some CAM software for 3D printing purposes, without using any of the existing geometry kernels. How hard can it be, right? I made some choices that seem weird but were done for very good reasons, and ended up implementing some things that are actually new and exciting. Here’s the story of the adventure so far. As t...

Die Sondersendung ist ein Podcast-Format des Sendezentrums. Bei dieser Sondersendung wollen wie mit Jugendlichen über ihre Erlebnisse vom Camp sprechen. Wir (Simon, Ebu und Gero) vom [Sondersendung Podcast](https://das-sendezentrum.de/sondersendung) erklären erstmal, was **Live-Podcasting** von einem normalen Vortragsprogramm unterscheidet und wie wir Gero und Ebu von remote zuschalten und trotzde...

Stopping global heating does not just mean building solar panels and wind turbines, and switching to electric vehicles. Many industrial processes have carbon emissions that cannot be avoided with today's technology. Producing cement, steel, glass, plastics, aluminium, and many other products will require new production processes. In the talk, I will discuss some of these examples and the huge chal...

Space missions need data networks, and it's not exactly a TCP/IP world up there. This talk will give an introduction to space data networks. Challenges at the physical layer are not in scope. Instead I will illustrate protocols, routing algorithms, and other schemes that were designed for networking in space. Space Communication is, as many others, a fractured discipline, with many idiosyncratic s...

Über die Konstruktion und den Bau eines Scanners, um die Überwachung durch die sogenannte Chatkontrolle zu verdeutlichen Regelmäßig gibt es politische Vorhaben, die Kommunikation von Bürger:innen massenhaft zu durchleuchten und auszuwerten. Wie verdeutlicht man Menschen die Gefahren, die derartige Systeme darstellen, wo die Technik dahinter sich doch so abstrakt anfühlt, nicht greifbar ist und "ma...

A discussion with Jeremy Hammond and Gabriella Coleman on the evolution of digital resistance, from direct action hacking to whistleblowing. How can hacktivists synergize with street activism to enact revolution? Can the lulz beat back the techno-fascist dystopia and their infosec enablers? We'll present strategies to strengthen decentralized networks, challenge government repression, and practice...
