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 ways and means that digital surveillance has been impacting sex worker rights of mobility and free expression in recent years. New laws enforcing the censorship of pornography and the collateral damages they levy on reproductive health and LGBTQ+ community building will be discussed as well as border crossing and payment processing. Information about how AI and facial recognition software target sex workers will be detailed as well as the tools, advocacy, social engineering strategies sex workers can use to fight back.\n\nThis talk is not limited to sex workers and their allies. It will include a primer on why sex worker rights include all human rights and show evidence that these laws are not limited to sex workers at all. LGBTQI+ people and reproductive health activists will be immediately impacted as well as all people who believe in the freedom of information.","original_language":"eng","persons":["Maggie

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.\r\n\r\nSpace Communication is, as many others, a fractured discipline, with many idiosyncratic solutions built for the needs of specific missions. Someone with decades of specialized industry experience could surely give a good picture of recurring problems and industry practices. Unfortunately I don't have those, but thankfully the people who do have been writing standards. (The presupposition becomes less and less true with time anyway, as agencies look towards inter-mission and inter-agency interoperability.) The primary basis for this talk are various documents, published by relevant working groups of the CCSDS and IETF.\r\n\r\nThis talk will be about the protocol ecosystem used in space networking, highlighting some clever technical solutions, and ending on some visions and challenges for the future. I presuppose some knowledge of classic internet protocols and the ISO-OSI layer model, but you should be able to follow the talk without it.\r\n\r\n(also check out: https://pretalx.c3voc.de/camp2023/talk/YZQYW9/ (german))","original_language":"eng","persons":["Johann A.

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.\nWe will go through a journey of critical findings in different targets and the constant battle between penetration testers, developers, and mid to upper management. This will help the audience get an understanding of how the industry behaves right now, what they (and what we) are doing wrong, and how the future of automotive security should be shaped, not only for the sake of security, but also for the sake of safety and reliability.\n\nThis talk will try to raise awareness on the current state of automotive security, how does the industry behave in the whole spectrum of it (100-year-old OEMs to 2-year-old OEMs and Tier 1 suppliers) and ultimately try to propose a way forward for both the automotive and security industries, with the goal being a safer and more reliable future for everyone, in and out of the streets.\n\nWorking with some of the biggest OEMs and Tier 1 suppliers on pre-production vehicles gave us an understanding and experience of the whole spectrum of developing a vehicle, from architectural design to homologation and sales. This led us in many realizations and pitfals that the automotive industry falls into, and in order to avoid another Miller/Valasek we have to educate the people of the industry. While most of the people/companies in this industry try to keep the gates closed for apparent reasons, we try to share as much as possible, with the hope of making a change to the industry that will have an impact on how and where it progresses in the future.","original_language":"eng","persons":["Thomas Sermpinis"],"tags":["camp2023","57024","2023","Milliways",""],"view_count":3951,"promoted":false,"date":"2023-08-17T23:00:00.000+02:00","release_date":"2023-08-18T00:00:00.000+02:00","updated_at":"2026-03-27T05:45:03.191+01:00","length":2759,"duration":2759,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57024-f4a121be-d2e9-533f-9fe9-4577cb81e05c.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57024-f4a121be-d2e9-533f-9fe9-4577cb81e05c_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57024-f4a121be-d2e9-533f-9fe9-4577cb81e05c.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57024-f4a121be-d2e9-533f-9fe9-4577cb81e05c.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57024-horror_stories_from_the_automotive_industry","url":"https://api.media.ccc.de/public/events/f4a121be-d2e9-533f-9fe9-4577cb81e05c","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"702f309e-50e5-5f0a-b2cb-3a3a30c08e91","title":"TrustMeRelay?

I will talk about my reverse engineering process and falsify Apple's privacy by design and access control claims.\n\nApple's iCloud Private Relay is a novel Internet privacy service allowing users to securely and privately browse the Internet. It is directly implemented into Apple's operating systems and included with all iCloud+ subscriptions. Compared to traditional VPN services, Private Relay's dual-hop architecture separates the knowledge of the user's IP address and their destination website between two different Relays. Apple operates the first Relay while the second one is by one of its four partners: Akamai, CloudFlare, or Fastly.\n\nApple claims its architecture enforces enhanced protection of users' privacy (\"privacy by design\") while still providing a high-performance browsing experience. Their president of software engineering, Craig Federighi, even mentions that Apple does not want users to have trust in them. Further, the company claims its service incorporates anti-abuse and fraud prevention mechanisms. As Private Relay validates any connection at the account and device level, website operators can trust them.\n\nI reverse engineer Private Relay's macOS implementation, present its involved technical components and how they collaborate. With that gained knowledge, I analyze authentication and authorization mechanisms deployed by Private Relay regarding potential ways of abuse. \nFurthermore, I review the privacy claims regarding the architecture and its deployment.","original_language":"eng","persons":["Heiko Kiesel"],"tags":["camp2023","57214","2023","Milliways",""],"view_count":1076,"promoted":false,"date":"2023-08-17T22:00:00.000+02:00","release_date":"2023-08-30T00:00:00.000+02:00","updated_at":"2026-04-01T15:15:10.265+02:00","length":2714,"duration":2714,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57214-702f309e-50e5-5f0a-b2cb-3a3a30c08e91.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57214-702f309e-50e5-5f0a-b2cb-3a3a30c08e91_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57214-702f309e-50e5-5f0a-b2cb-3a3a30c08e91.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57214-702f309e-50e5-5f0a-b2cb-3a3a30c08e91.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57214-trustmerelay_investigating_apple_s_icloud_private_relay","url":"https://api.media.ccc.de/public/events/702f309e-50e5-5f0a-b2cb-3a3a30c08e91","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"7d1c7f63-b537-5dd6-ba2f-e944c967b40c","title":"Defeating planned obsolescence for Cisco Meraki switches","subtitle":null,"slug":"camp2023-57142-defeating_planned_obsolescence_for_cisco_meraki_switches","link":"https://pretalx.c3voc.de/camp2023/talk/Z87KAX/","description":"Cisco Meraki Ethernet switches are cloud-managed and require a license to function, or do they?

The goal is to empower Internet users, giving them more information and control about the paths their packets take through the network. Of course this means that, with the right kind of configuration, the SCION-enabled networking stack of your device could automatically steer your outgoing traffic to, for example,\n\n- boycott networks that are known to have unnecessarily high carbon footprints (e.g., that buy power from coal plants),\n- prefer networks that operate in areas where there is a (temporary) surplus of electricity from renewables,\n- avoid traversing networks that fall under certain dubious jurisdictions, etc.\n\nThis talk will briefly look at how the Internet currently works and what issues SCION aims to address. We'll discuss SCION itself in a bit more detail, reviewing its architecture and design decisions before turning to the exciting prospects that \"path awareness\" can bring to Internet users, especially in terms of a greener Internet.

The size of the screen is not the problem because you can cast it to a monitor, and useful embedded computers often don't have their own screens.","original_language":"eng","persons":["Matthew Croughan"],"tags":["camp2023","57129","2023","Bits \u0026 Bäume",""],"view_count":5003,"promoted":false,"date":"2023-08-15T16:05:00.000+02:00","release_date":"2023-08-16T00:00:00.000+02:00","updated_at":"2026-04-01T02:30:02.817+02:00","length":309,"duration":309,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57129-6553838c-8d09-5d60-8491-94296e3c9caa.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57129-6553838c-8d09-5d60-8491-94296e3c9caa_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57129-6553838c-8d09-5d60-8491-94296e3c9caa.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57129-6553838c-8d09-5d60-8491-94296e3c9caa.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57129-the_nix_phone_and_the_end_of_android","url":"https://api.media.ccc.de/public/events/6553838c-8d09-5d60-8491-94296e3c9caa","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"4146f6ee-ac0d-5dc2-8ac6-8a06f52e03a9","title":"Demystifying AI","subtitle":"","slug":"camp2023-57262-demystifying_ai","link":"https://pretalx.c3voc.de/camp2023/talk/GQRTAS/","description":"Der Vortrag \"Demystifying AI\"  soll den Zuhörerinnen eine fundierte und verständliche Einführung in das Thema Artificial Intelligenz (AI) bieten. Der Erfolg von ChatGPT hat den Eindruck erweckt, dass AI langsam den Menschen ersetzen kann. Zusätzlich haben die großen Player ein großes Interesse daran AI als eine schwierige und komplexe Technologie darzustellen. Mit diesem Talk trete ich diesem Trend entgegen und blicke hinter die Kulissen des Maschinellen Lernens. Das Ziel des Talks ist es, die Grundlagen des Maschinellen Lernens zu erklären, da dies die aktuelle Form der AI ist, die wir momentan nutzen. Zusätzlich möchte ich versuchen, den schwer verständlichen Jargon aufzubrechen und damit besser greifbar zu machen.\r\n\r\nDer Talk beginnt mit einer Erläuterung der verschiedenen Arten des Maschinellen Lernens. Durch Beispiele werde ich erklären, wie diese Lernmethoden funktionieren und welche Probleme sie lösen können. Das überwachte Lernen beinhaltet das Trainieren eines Modells anhand von Eingabe- und Ausgabedaten, während das unüberwachte Lernen nach Mustern und Gruppierungen in den Daten sucht. Beim verstärkenden Lernen interagiert das Modell mit einer Umgebung, um Belohnungen zu maximieren. Dieser Überblick ermöglicht es den Zuhörerinnen ein umfassenderes Verständnis für die Funktionsweise und Anwendungsbereiche des maschinellen Lernens zu bekommen. Ich werde dabei besonders auf die Gemeinsamkeiten der verschiedenen Ansätze eingehen, um den Teilnehmerinnen die Möglichkeit zu geben den grundlegenden Zusammenhang zu erkennen.  \r\n  \r\nDen Schwerpunkt des Vortrags werde ich darauf legen, die mathematischen Grundlagen des Maschinellen Lernens zu erklären. Dabei werde ich erläutern, wie das Training von ML-Modellen durchgeführt wird und welche Schritte dabei im Detail stattfinden. Es wird deutlich, dass das Training eines ML-Modells im Wesentlichen auf der Optimierung einer Kostenfunktion basiert, um die besten Modellparameter zu finden. Die Zuhörerinnen werden verstehen, wie das Training mathematisch formuliert ist und welche Algorithmen dabei verwendet werden, um die Modellgewichte anzupassen und die Fehler zu minimieren.  \r\n  \r\nAm Ende des Vortrags werde ich die Herausforderungen und Fallstricke des maschinellen Lernens diskutieren. Hierbei werden Themen wie Datenvorverarbeitung, Overfitting, Bias und Erklärbarkeit kurz behandelt, um den Zuhörerinnen ein Verständnis der potenziellen Schwierigkeiten beim Einsatz von Maschinellem Lernen zu vermitteln. Ich werde erläutern, wie die Qualität der Daten einen großen Einfluss auf die Leistung des Modells hat und welche Schritte unternommen werden können, um die Datenqualität zu verbessern. Zudem werde ich erklären, wie Overfitting vermieden werden kann, indem Modelle an zusätzlichen Testdaten überprüft werden. Die Diskussion über Bias und Erklärbarkeit soll die Zuhörerinnen sensibilisieren, dass maschinelles Lernen nicht frei von Vorurteilen ist und dass es wichtig ist, die Entscheidungen und Vorhersagen von Modellen nachvollziehen und erklären zu können.  \r\n  \r\nAbschließend werde ich praktische Tipps und Ressourcen für den Einstieg in das Maschinelle Lernen geben. Die Teilnehmerinnen erhalten Empfehlungen für Bücher, Online-Kurse und Communitys, um ihr Wissen weiter auszubauen und eigene Projekte zu starten. \r\nDurch die Inhalte meines vortrags möchte ich dazu beitragen,  den Einsatz von AI differenziert zu betrachten und kritisch zu hinterfragen.","original_language":"deu","persons":["jate"],"tags":["camp2023","57262","2023","NORTx"],"view_count":2002,"promoted":false,"date":"2023-08-15T17:15:00.000+02:00","release_date":"2023-08-16T00:00:00.000+02:00","updated_at":"2026-03-22T11:30:10.882+01:00","length":2827,"duration":2827,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57262-4146f6ee-ac0d-5dc2-8ac6-8a06f52e03a9.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57262-4146f6ee-ac0d-5dc2-8ac6-8a06f52e03a9_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57262-4146f6ee-ac0d-5dc2-8ac6-8a06f52e03a9.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57262-4146f6ee-ac0d-5dc2-8ac6-8a06f52e03a9.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57262-demystifying_ai","url":"https://api.media.ccc.de/public/events/4146f6ee-ac0d-5dc2-8ac6-8a06f52e03a9","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"9fe6612b-92f0-5bca-92d0-a4618c0941fb","title":"Ethical hacking, good intentions and questionable outcomes","subtitle":null,"slug":"camp2023-57306-ethical_hacking_good_intentions_and_questionable_outcomes","link":"https://pretalx.c3voc.de/camp2023/talk/ANGUCW/","description":"We've all been there, we knocked a company offline while doing some well intended security testing.

Did you know it was a raspberry pie in a broom closet?\n\nThis talk discusses ethical boundaries, the existence and lack of them, but also the grey areas in between. The spark for this talk has been initiated from the need to ensure that all forms of security testing would be beneficial to all parties concerned and within some ethical boundaries. From secret hacking techniques to open blog posts and CVE's. Hopefully this talk will spark some discussions within the community so we can all go home with a clear conscience and preserve moral high ground.","original_language":"eng","persons":["Joakim Tauren"],"tags":["camp2023","57306","2023","Milliways",""],"view_count":283,"promoted":false,"date":"2023-08-17T16:00:00.000+02:00","release_date":"2023-08-18T00:00:00.000+02:00","updated_at":"2026-01-13T18:15:22.212+01:00","length":2076,"duration":2076,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57306-9fe6612b-92f0-5bca-92d0-a4618c0941fb.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57306-9fe6612b-92f0-5bca-92d0-a4618c0941fb_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57306-9fe6612b-92f0-5bca-92d0-a4618c0941fb.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57306-9fe6612b-92f0-5bca-92d0-a4618c0941fb.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57306-ethical_hacking_good_intentions_and_questionable_outcomes","url":"https://api.media.ccc.de/public/events/9fe6612b-92f0-5bca-92d0-a4618c0941fb","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"3b5b1f11-37c7-550a-bb67-3f747c30add9","title":"Peeking over the tape moat","subtitle":null,"slug":"camp2023-57227-peeking_over_the_tape_moat","link":"https://pretalx.c3voc.de/camp2023/talk/CSYA7B/","description":"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.\nTape 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 make it an attractive option for keeping data safe over longer periods of time.\nDoomsayers have long foretold the death of tape, yet there has never been more data stored on it than today.

Currently, primary Internet based attacks are analyzed, but it is greatly neglected that with the help of the Internet measurement verifiable statements can be made about the real world. Through global Internet scans and a passive blackhole sensor network, we can identify digital and conventional attacks and their effects in this case study on the territory of Ukraine. \n\nWe will show that it is possible to detect where in Ukraine, Russian attack-related power outages occur and how long they last. For this purpose, we will also scan and analyze 2 major attack waves that occurred about 5 months apart in detail the service availability of more than 400,000 static IP addresses every 4 hours for several months. This long-term period will also allow us to determine whether and if so, how resilient the Ukrainian power supply has become against Russian missile attacks. In addition, we will also analyze other data such as ESA radar images and correlate the degree of destruction of certain regions in Ukraine with our scan data. This method could be used, for example, to support NGOs to determine the need for mobile power generators in certain regions.\n\nFurthermore, using BGP data and media information, we will show that Russian forces in Kherson are attempting to route network traffic from local ISPs through Russian territory to gain a tactical advantage.\n\nFinally, we will show that through a blackhole network of about 1000 IP addresses it is possible to detect certain DDOS attacks against Ukrainian infrastructures or government websites. The analysis of the temporal course of the attacks shows interesting temporal patterns that suggest some kind of campaign.","original_language":"eng","persons":["Johannes Klick"],"tags":["camp2023","57125","2023","Milliways",""],"view_count":390,"promoted":false,"date":"2023-08-18T17:00:00.000+02:00","release_date":"2023-08-19T00:00:00.000+02:00","updated_at":"2026-03-29T19:00:07.249+02:00","length":2557,"duration":2557,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57125-b2dfbe1a-1173-5f4b-94ac-218bd99126b6.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57125-b2dfbe1a-1173-5f4b-94ac-218bd99126b6_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57125-b2dfbe1a-1173-5f4b-94ac-218bd99126b6.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57125-b2dfbe1a-1173-5f4b-94ac-218bd99126b6.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57125-how_to_use_internet_scans_and_passive_measurements_to_analyze_russian_attacks_and_their_impact_in_ukraine","url":"https://api.media.ccc.de/public/events/b2dfbe1a-1173-5f4b-94ac-218bd99126b6","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"09095673-b033-5745-ae97-403bea8203c5","title":"A Guided Tour through Tor Network Health and Performance","subtitle":null,"slug":"camp2023-57172-a_guided_tour_through_tor_network_health_and_performance","link":"https://pretalx.c3voc.de/camp2023/talk/SMB8SM/","description":"Since the last time, we were all at camp, several significant changes have happened within the Tor network ecosystem, both technically and socially.

They enable one to outsource randomness computations to another party without having to trust them or make any compromises in confidentiality of the inputs. The most common benefit of using an OPRF, is that it adds strong privacy guarantees to protocols. A well-placed OPRF can also provide confidentiality without needing a PKI infrastructure. In some cases an OPRF can provide strong security guarantees that traditional systems cannot provide. OPRFs are truly one of the most exciting and underappreciated cryptographic building blocks of the last decade.\n\nIn this talk I am will explain how OPRFs work, properties can achieve, and how OPRFs are used in various protocols. I am going to show some examples of existing free software tools which use or provide OPRFs and how these tools compare to alternative solutions.\n\nThe talk is structured in two parts, a theoretic part which explains various types of OPRFs, their properties and where and how these are beneficial. And in the second part I will show concrete free software implementations: liboprf, libopaque, sphinx (a password storage that could be run by the NSA) and klutshnik, a threshold key management system, all authored by Yours Truly. I will also touch briefly on standardisation efforts of OPAQUE and OPRF by the IRTF CFRG, to which I contribute.\n\nOther examples I will bring will include private set intersection (used for contact discovery or haveibeenpwned-style privacy- respecting compromised account checks), private information retrieval, single-sign-on with privacy, deduplication and secure pattern matching.","original_language":"eng","persons":["stf"],"tags":["camp2023","57085","2023","Milliways",""],"view_count":222,"promoted":false,"date":"2023-08-17T14:00:00.000+02:00","release_date":"2023-08-18T00:00:00.000+02:00","updated_at":"2026-02-18T11:30:14.411+01:00","length":2737,"duration":2737,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57085-9dbb3f1e-87e6-5e26-994f-dcf5b7ccf592.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57085-9dbb3f1e-87e6-5e26-994f-dcf5b7ccf592_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57085-9dbb3f1e-87e6-5e26-994f-dcf5b7ccf592.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57085-9dbb3f1e-87e6-5e26-994f-dcf5b7ccf592.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57085-fantastic_oprfs_and_where_to_find_them","url":"https://api.media.ccc.de/public/events/9dbb3f1e-87e6-5e26-994f-dcf5b7ccf592","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"c584a5f7-88dd-5c04-a8ba-629ac4c47eff","title":"Delta Chat messenger","subtitle":"unlocking the potential of e-mail and the web","slug":"camp2023-57191-delta_chat_messenger","link":"https://pretalx.c3voc.de/camp2023/talk/UL7CQU/","description":"[Delta Chat](https://delta.chat) is an e-mail based messenger that works on all platforms.

Within a few months tens of new Hackspaces were founded all over the world. And while the fun lasted for a while, we are now in the midst of a global crisis, that its least is urgently asking for mitigation strategies. At Bio-Hack-Spaces we create mycelium based build materials, research new ways of growing (or foraging) our own food, build technological bridges to nudge nature in our desired direction or tinker on devices that help us to better understand our surroundings. \nThe Biopunk movement is in almost every regard comparable to the old school hacker movement. It is about resilience, creativity and autonomy. And yet, there is one fundamental difference: While you bend a computer to your will, you can only politely ask anything that lives. So in that sense, Biopunk is about understanding that we aren’t separated from nature, we are nature. And nature will teach us something that society needs more than anything else: the ability to listen.","original_language":"eng","persons":["Julian"],"tags":["camp2023","57206","2023","Bits \u0026 Bäume",""],"view_count":447,"promoted":false,"date":"2023-08-19T15:30:00.000+02:00","release_date":"2023-08-19T00:00:00.000+02:00","updated_at":"2026-01-28T15:15:11.742+01:00","length":1269,"duration":1269,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57206-c503ca71-e259-5d04-8076-6d313e14f9f4.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57206-c503ca71-e259-5d04-8076-6d313e14f9f4_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57206-c503ca71-e259-5d04-8076-6d313e14f9f4.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57206-c503ca71-e259-5d04-8076-6d313e14f9f4.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57206-nerds_touching_grass","url":"https://api.media.ccc.de/public/events/c503ca71-e259-5d04-8076-6d313e14f9f4","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"5ce92d94-c6e3-5955-aacb-2ffe97b08cfc","title":"Freie interaktive Karten mit VersaTiles","subtitle":null,"slug":"camp2023-57248-freie_interaktive_karten_mit_versatiles","link":"https://pretalx.c3voc.de/camp2023/talk/WJ3AAU/","description":"Interaktive Karten sind aus dem Internet nicht mehr wegzudenken.

The \"I Love Free Software Day\" (https://ilovefs.org) provides a platform for individuals and organisations to do exactly this, showing appreciation. But it is crucial to recognize that our appreciation for Free Software should extend far beyond this single day. This talk highlights the significance of the \"I Love Free Software Day\" as a platform for expressing support, love, and gratitude towards the developers and contributors who make Free Software possible.\n\nThroughout the presentation, we will showcase memorable moments and successful initiatives from past celebrations, demonstrating the collective efforts to acknowledge and honor the impact of Free Software. We will discuss ideas and strategies for making the upcoming \"I Love Free Software Day\" even more remarkable.\n\nHowever, it is essential to emphasize that our expressions of love and support for Free Software should not be limited to just one day. While the \"I Love Free Software Day\" serves as a catalyst for celebration, it should inspire us to continue demonstrating our gratitude throughout the year. We will explore ways to incorporate ongoing appreciation into our daily lives, such as contributing to Free Software projects, advocating for their importance, and recognizing the efforts of developers and contributors regularly also in a financial way.\n\nBy extending our appreciation beyond a single day, we can cultivate a culture of continuous support for Free Software. We invite everyone interested in Free Software to join us in this endeavor, as we strive to create an environment where gratitude and acknowledgment become integral parts of our interactions within the Free Software community.\n\nLet us embrace the \"I Love Free Software Day\" (https://ilovefs.org) as a starting point, a reminder of the significance of Free Software, and a call to action to express our love and support throughout the year. Together, we can build a community that values and appreciates the tireless efforts of Free Software developers and contributors, making a lasting impact on the future of software freedom.","original_language":"eng","persons":["bonnie"],"tags":["camp2023","57053","2023","Bits \u0026 Bäume",""],"view_count":95,"promoted":false,"date":"2023-08-15T18:00:00.000+02:00","release_date":"2023-08-19T00:00:00.000+02:00","updated_at":"2026-02-01T22:45:08.747+01:00","length":899,"duration":899,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57053-3184831e-104c-5747-aeab-9066cf35fc07.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57053-3184831e-104c-5747-aeab-9066cf35fc07_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57053-3184831e-104c-5747-aeab-9066cf35fc07.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57053-3184831e-104c-5747-aeab-9066cf35fc07.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57053-sharing_the_power_of_appreciation","url":"https://api.media.ccc.de/public/events/3184831e-104c-5747-aeab-9066cf35fc07","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"13b445ab-36d3-53cc-8ef4-2379281961f0","title":"Fake 10Gb until you make 10Gb","subtitle":null,"slug":"camp2023-57212-fake_10gb_until_you_make_10gb","link":"https://pretalx.c3voc.de/camp2023/talk/GBQQUN/","description":"**THIS TALK WILL BE HELD IN \"RESCUE\" MODE DUE TO PRESENTER'S HARDWARE FAILING**\n\nBuilding your own hardware to work with 10 Gigabit Ethernet… without access to measurement or simulation equipment.

Passive single-port adapters that can read diagnostic information from optical transceivers are common and easy, but how about something with 4 ports and active circuitry?\n\nWell, electrons don't really like being pushed around at GHz frequencies, start clinging to edges and corners, and turn around and go back the way they came when that's the easier path… HF circuit design has a well-earned aura of respect. One of the well-known reference books is in fact titled \"High Speed Digital Design: A Handbook of Black Magic\" and assumes you have a fancy (= expensive) electronics lab with nice gear.\n\nLet's, uh, just ignore all that and see the result of building high-speed (10GE - 10.3125Gbaud, 5.16GHz) electronics with just basic microcontroller experience!\n\nNB: this talk will be incredibly boring (or even annoying?) to anyone with actual HF design experience.

No idea where we would find enough room for it or if it would actually be used, but of course we'd be interested! Even if we couldn't repair the original electronics it would still serve as a good base to build a cocktail bot for Roboexotica, the festival for Cocktailrobotics. So roughly a month later the machine arrived at Metalab.\nAfter a few months of collecting (additional) dust and annoying a few members, we started the quest to get this machine back to work and to explore the (questionable) world of industrial coffee vending legacy, from hardware, over electronics to software architecture.

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.\r\n\r\nAs the adoptive maintainer of one piece of 3D printing toolchain (ImplicitCAD, a programmable 3D modelling tool), I made the possibly unwise decision to implement another part of the toolchain - HSlice, a slicer. For a number of reasons I’ll get into in detail later, I decided to not use any of the existing multi-million-LoC geometry kernels, to implement the whole thing from first principles in Haskell, and to use some exciting new mathematics. All of those decisions were made for good reasons, and all of them came back to bite me. I’m here to tell you about what I’ve built so far, how I ended up as the singular intersection of these technologies, and how much I hate floating point. Then, I’ll tell you what it’s like implementing things whose only documentation is research papers, with math developed this century and algorithms that are still in development now. I’ll tell you about some incredibly cool algorithms involving crashing Austrian motorcycles and attempt to recruit you to work on this stuff too, for free.","original_language":"eng","persons":["Julia Longtin"],"tags":["camp2023","57408","2023","NORTx"],"view_count":157,"promoted":false,"date":"2023-08-17T17:50:00.000+02:00","release_date":"2023-08-29T00:00:00.000+02:00","updated_at":"2026-04-01T20:00:05.978+02:00","length":2750,"duration":2750,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57408-16626141-40a9-5fbb-b538-3bb7c5b8580d.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57408-16626141-40a9-5fbb-b538-3bb7c5b8580d_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57408-16626141-40a9-5fbb-b538-3bb7c5b8580d.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57408-16626141-40a9-5fbb-b538-3bb7c5b8580d.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57408-a_geometry_engine_from_first_principles","url":"https://api.media.ccc.de/public/events/16626141-40a9-5fbb-b538-3bb7c5b8580d","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"5cbef558-4bd4-5477-8f2d-debede0a3fc8","title":"Autonomie in Waffensystemen","subtitle":null,"slug":"camp2023-57176-autonomie_in_waffensystemen","link":"https://pretalx.c3voc.de/camp2023/talk/R9CDPK/","description":"Der Vortrag gibt eine Einführung in aktuelle Entwicklungen im Kontext von autonomen Waffensystemen bzw.

Warum plant das BMJ eine Digitale-Gewalt-Gesetz, das diejenigen identifizieren und bestrafen soll, die in Messengern über schlechte Restaurants lästern, und warum ändert sich noch immer nichts an der Pflicht zur Adresse im Impressum? Das und mehr im Update zum Stand der Dinge bei der Digitalen Gewalt.\n\nVier Jahre nach [\"Was tun gegen Digitale Gewalt gegen Frauen\"](https://media.ccc.de/v/Camp2019-10346-was_tun_gegen_digitale_gewalt_gegen_frauen), meinem Talk im letzten Camp, ist es Zeit für ein Update. \n\nDie Ampel hat sich ein Digitale-Gewalt-Gesetz in den Koalitionsvertrag geschrieben und dazu gerade erste 'Eckpunkte' vorgelegt. Warum das völlig am Problem vorbeigeht und dazu möglicherweise für uns alle eine Gefahr darstellt, werde ich in diesem Talk erläutern. Das Justizministerium möchte nämlich nicht nur diejenigen identifizieren, die andere auf Social-Media-Plattformen bedrohen und beleidigen, sondern auch noch viele andere. Die Sicherheitsbehörden freuen sich schon. \n\nAber vor allem: Das löst nicht die vielfältigen Probleme der digitalen Gewalt. Die findet nicht nur auf Plattformen statt, sondern in Partnerschaften und Ex-Partnerschaften, durch Bekannte und Unbekannte, unter Kolleg*innen, in Familien oder Nachbarschaften. Digitale Technologien werden für alle denkbaren Formen der Manipulation und Kontrolle benutzt: Mitlesen von E-Mails, sichtbare und unsichtbare Kameras in öffentlichen und privaten Räumen, AirTags in Spielzeug, Handtaschen, Fahrzeugen. Spyware wird nicht nur von autokratischen Regimes eingesetzt, sondern auch zur Überwachung der eigenen Familie. \n\nWas hat sich in den letzten vier Jahren verändert? Wer hilft den Betroffenen und wie können sie sich selbst helfen? Darum geht es in diesem Talk.","original_language":"deu","persons":["Anne Roth"],"tags":["camp2023","57178","2023","Bits \u0026 Bäume",""],"view_count":666,"promoted":false,"date":"2023-08-18T17:00:00.000+02:00","release_date":"2023-08-29T00:00:00.000+02:00","updated_at":"2026-03-31T18:30:04.689+02:00","length":2756,"duration":2756,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57178-3d0fdc9c-3f39-5ab0-912a-9169780409c1.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57178-3d0fdc9c-3f39-5ab0-912a-9169780409c1_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57178-3d0fdc9c-3f39-5ab0-912a-9169780409c1.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57178-3d0fdc9c-3f39-5ab0-912a-9169780409c1.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57178-digitale_gewalt","url":"https://api.media.ccc.de/public/events/3d0fdc9c-3f39-5ab0-912a-9169780409c1","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"84d8934c-1bb3-5fb1-9f4a-f1b509f0eea5","title":"Chaos Zone","subtitle":"Chaos Family","slug":"camp2023-57769-chaos_zone","link":"https://pretalx.c3voc.de/camp2023/talk/5659/","description":".\n\nChaos Family","original_language":"deu","persons":[],"tags":["camp2023","57769","2023","Chaos Family","C3VOC.tv"],"view_count":216,"promoted":false,"date":"2023-08-18T17:00:00.000+02:00","release_date":"2023-08-29T00:00:00.000+02:00","updated_at":"2026-02-14T00:00:06.733+01:00","length":1675,"duration":1675,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57769-84d8934c-1bb3-5fb1-9f4a-f1b509f0eea5.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57769-84d8934c-1bb3-5fb1-9f4a-f1b509f0eea5_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57769-84d8934c-1bb3-5fb1-9f4a-f1b509f0eea5.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57769-84d8934c-1bb3-5fb1-9f4a-f1b509f0eea5.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57769-chaos_zone","url":"https://api.media.ccc.de/public/events/84d8934c-1bb3-5fb1-9f4a-f1b509f0eea5","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"1ec317a2-d5d4-5472-abf0-9f8dcb1e6b45","title":"Read and Manipulate Network Traffic on Android with mitmproxy","subtitle":null,"slug":"camp2023-57313-read_and_manipulate_network_traffic_on_android_with_mitmproxy","link":"https://pretalx.c3voc.de/camp2023/talk/L7V9HF/","description":"In this talk, we take a first look at the tool mitmproxy.

Doch kaum einer hält sich daran.\nDatengetriebenes 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 Zuge einer fehlgeleiteten Digitalisierung Werkzeuge ein, mit denen Menschen überwacht werden. Viele Unternehmen nutzen IT-Tools, deren Funktionsweise sie kaum durchsteigen und deren Sicherheit sie nicht gewährleisten können.

Not only will machine learning be used to find and report previously unknown images and videos, but text messages will also be analysed and searched for suspicious behaviour. Encrypted communication is not exempt, so that implementation of the plans would be a massive attack on end-to-end encryption and lead to the widespread use of client-side scanning. It is obvious that the use of these dystopian surveillance tools would not be limited to abusive depictions of children and young people in the medium term. Spain which will hold the EU-presidency for the next half year, already declared it would prefer a complete ban on E2EE.\n\nIn addition to various other measures, e.g. network blocking, the plans provide for mandatory age verification for app stores, which would not only affect Google and Apple's app stores. If the EU's plans go through, free Linux distributions would not only have to carry out age verification, but would also have to check all applications themselves. \n\nThe EU legislative process is long, tough and confusing. This talk will not only be about where we are with chat-control, but also about which EU institutions are at which levers, when, how and where.\n\nAnd above all, we want to discuss with you what we can still do to stop this dystopian surveillance machine.","original_language":"eng","persons":["Tom Jennissen","Konstantin Macher","khaleesi"],"tags":["camp2023","57226","2023","Milliways",""],"view_count":632,"promoted":false,"date":"2023-08-16T21:00:00.000+02:00","release_date":"2023-08-17T00:00:00.000+02:00","updated_at":"2026-03-10T14:45:06.615+01:00","length":2580,"duration":2580,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57226-9ee85bab-dedf-5766-8e7b-832a557d9c57.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57226-9ee85bab-dedf-5766-8e7b-832a557d9c57_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57226-9ee85bab-dedf-5766-8e7b-832a557d9c57.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57226-9ee85bab-dedf-5766-8e7b-832a557d9c57.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57226-chat_control","url":"https://api.media.ccc.de/public/events/9ee85bab-dedf-5766-8e7b-832a557d9c57","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"5fd4cc39-7046-50fd-86fb-40a87a247ea6","title":"Meshenger","subtitle":"True P2P Phone Calls","slug":"camp2023-57107-meshenger","link":"https://pretalx.c3voc.de/camp2023/talk/9XPJNG/","description":"Meshenger is a P2P Android phone app that started out as a demo for community mesh networks.\n\nMeshenger started out as an idea to promote off the grid mesh networks and has now reached its initial goal.

Welche Zukunft darf es sein: Gerecht und frei zugänglich für alle, oder doch lieber in den Händen von wenigen?\n\nEs gibt offene Fragen: Wer produziert Wissen unter welchen Rahmenbedingungen? Ist das gerecht? Wie können wir uns als Menschen um mehr Gerechtigkeit bemühen und verhindern, dass die Macht der wirtschaftlichen Giganten unter dem Label \"KI\" noch weiter wächst?

They are based on vastly different technologies: one real, one just made up. Using indie game classic *Celeste* I show how they help relive the glory days of the bedroom coder.\r\n\r\nProgramming a game for embedded microcontrollers can scratch the same itch as programming for vintage 8-bit systems: getting close to the metal, being frugal with computing resources and showing disdain for wasteful software bloat. Combine this with pixel art graphics that enable anyone to be an artist. \r\n\r\nThis talk describes the continuing appeal of pixel art graphics, then shows the journey of porting the *PICO-8* classic *Celeste* to a system with 264 Kilobytes of RAM. After buggy attempts in C and modern C++ the project was rewritten a second time in embedded Rust and may evolve into a new beginner-friendly game framework in the embedded space. The harsh limitations of the microcontroller prevent feature creep and free up creativity. While getting close to the metal leads to deeper understanding.","original_language":"eng","persons":["Pixelpunker"],"tags":["camp2023","57155","2023","NORTx"],"view_count":266,"promoted":false,"date":"2023-08-16T16:20:00.000+02:00","release_date":"2023-08-17T00:00:00.000+02:00","updated_at":"2025-11-03T23:30:04.505+01:00","length":1374,"duration":1374,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57155-f0dc0742-e256-5853-97d0-e7ec231cd672.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57155-f0dc0742-e256-5853-97d0-e7ec231cd672_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57155-f0dc0742-e256-5853-97d0-e7ec231cd672.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57155-f0dc0742-e256-5853-97d0-e7ec231cd672.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57155-celeste","url":"https://api.media.ccc.de/public/events/f0dc0742-e256-5853-97d0-e7ec231cd672","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"3978a158-e922-56e8-bb1f-2fdddc415041","title":"NOC","subtitle":"Frag die Teams","slug":"camp2023-teams-noc","link":"https://pretalx.c3voc.de/camp2023/talk/camp20231989/","description":"Leyer talks to the Internet-Manufakur aka \"Network Operation Center\" about their work.\r\n\r\nThis time he is actually told 3 minutes before that its broadcasted LIVE – but it does not really matter to him anymore.","original_language":"eng","persons":[],"tags":["camp2023","57763","2023","Frag die Teams","C3VOC.tv","CCC"],"view_count":1088,"promoted":false,"date":"2023-08-17T15:00:00.000+02:00","release_date":"2023-08-17T00:00:00.000+02:00","updated_at":"2026-02-01T14:00:09.133+01:00","length":2107,"duration":2107,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57763-3978a158-e922-56e8-bb1f-2fdddc415041.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57763-3978a158-e922-56e8-bb1f-2fdddc415041_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57763-3978a158-e922-56e8-bb1f-2fdddc415041.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57763-3978a158-e922-56e8-bb1f-2fdddc415041.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-teams-noc","url":"https://api.media.ccc.de/public/events/3978a158-e922-56e8-bb1f-2fdddc415041","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"37c37538-83d1-4678-bef8-35af78653609","title":"The flow3r Badge – Assembly Instructions","subtitle":"","slug":"camp2023-101-the-flow3r-badge-assembly-i","link":"https://c3voc.de","description":"How to grow your flow3r\r\n\r\n","original_language":"eng","persons":[],"tags":["import","101","2023","flow3r"],"view_count":5647,"promoted":false,"date":"2023-08-12T13:23:00.000+02:00","release_date":"2023-08-14T00:00:00.000+02:00","updated_at":"2026-04-04T00:00:06.673+02:00","length":623,"duration":623,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/101-37c37538-83d1-4678-bef8-35af78653609.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/101-37c37538-83d1-4678-bef8-35af78653609_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/101-37c37538-83d1-4678-bef8-35af78653609.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/101-37c37538-83d1-4678-bef8-35af78653609.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-101-the-flow3r-badge-assembly-i","url":"https://api.media.ccc.de/public/events/37c37538-83d1-4678-bef8-35af78653609","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"8805e64f-3eb0-52b3-a660-33f51d3b3c1a","title":"Jens Spahns credit score is \"very good\"","subtitle":"","slug":"camp2023-57571-jens_spahns_credit_score_is_very_good","link":"https://pretalx.c3voc.de/camp2023/talk/NHHEZN/","description":"A case study on how to use security research as a method of direct action.\r\n\r\nIn the context of the CCC, we usually do our vulnerability disclosures responsibly. So we ensure that a vulnerability is closed or at least disclosed to the responsible entity for a certain amount of time before discussing it publicly. The practice of responsible disclosure is more than two decades old and has become the gold standard in handling vulnerabilities as a security researcher.\r\n\r\nOn the other hand, responsible disclosure often also minimizes a vulnerability's impact in public debates and, therefore, is an excellent way to keep everybody safe. Still, it also reduces the usefulness of security research as a method of direct action.\r\n\r\nIn this talk, I would like to explain based on two examples (the ID-Wallet as well as the Bonify case) in which cases I think the impact of a vulnerability can be maximized by shitposting it on Twitter while keeping everyone - except Jens Spahn and Helge Braun - safe.

This talk will delve deep into the technological advances, system designs, and emerging cybersecurity concerns of satellite internet constellations. It promises to be an eye-opening exploration of our shared cybernetic future that beckons us to the stars.\r\n\r\nIn this  session, we will journey into the fascinating world of satellite constellations, focusing on SpaceX's Starlink, Amazon's Project Kuiper, and other key players aiming to democratize internet access on a global scale. The audience can expect to gain a solid understanding of the underlying technical aspects, as well as insight into the broader implications and challenges these ambitious projects present.\r\n\r\nThe talk will be segmented into four primary sections:\r\n\r\n**I. Technology Overview**\r\n\r\nWe will have a comprehensive look at the mechanics of satellite constellations. This includes their construction, launch, on-orbit adjustments, ground-station architecture, and the way they employ laser interlinks to provide low latency broadband coverage across the globe.\r\n\r\n**II. Advances and Innovations**\r\n\r\nMoving from the basics, we'll dive into the recent technological breakthroughs and evolutions that make these projects possible and viable. This includes lighter, smaller satellites, sophisticated launch and deployment strategies, and innovative user terminal designs.\r\n\r\n**III. Security Implications**\r\n\r\nThe expansion of the internet's physical infrastructure into space comes with significant security implications. We'll discuss potential attack vectors, satellite hacking scenarios, and the steps these companies are taking to ensure data security and system integrity in the hostile environment of space.\r\n\r\n**IV. The Hacker's Perspective**\r\n\r\nFinally, we will explore the hacker's role in this new era. With the final frontier now becoming a playground for connectivity, there will be ethical considerations, potential vulnerabilities to uncover, and perhaps even opportunities to contribute to a secure and fair utilization of space-born internet.\r\n\r\nTogether, we'll paint a detailed picture of the fast-paced developments in this sector, offering both a technical deep dive and a wider societal perspective. By exploring uncharted territories and understanding the challenges we face as society, as users, as engineers, and as hackers , we can inspire innovative solutions and navigate the path to the future of connectivity with greater clarity and purpose.","original_language":"eng","persons":["Oliver Germer"],"tags":["camp2023","57307","2023","NORTx"],"view_count":645,"promoted":false,"date":"2023-08-15T18:15:00.000+02:00","release_date":"2023-08-16T00:00:00.000+02:00","updated_at":"2026-01-28T08:45:10.506+01:00","length":2771,"duration":2771,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57307-e7f365a6-c910-5c96-bd12-fa90fc866719.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57307-e7f365a6-c910-5c96-bd12-fa90fc866719_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57307-e7f365a6-c910-5c96-bd12-fa90fc866719.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57307-e7f365a6-c910-5c96-bd12-fa90fc866719.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57307-cosmic_connectivity","url":"https://api.media.ccc.de/public/events/e7f365a6-c910-5c96-bd12-fa90fc866719","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"9ad51a92-6c50-565f-aab9-3d65f673f709","title":"#CCCamp23 Review","subtitle":null,"slug":"camp2023-57105-cccamp23_review","link":"https://pretalx.c3voc.de/camp2023/talk/ACVRNU/","description":"Zahlen, Daten, Fakten.

Unter dem nicht unproblematischen Label der \"Digitalen Souveränität\" sind zahlreiche Projekte gestartet, die meisten tatsächlich sinnvoll. Dabei ist durch konsequente Beachtung von Open Source eine zwangsläufige Kette entstanden.\n\nDadurch bekommt Open Source Vorrang, weil auf OpenCode  Software nur mit einer OSI[1] Lizenz veröffentlicht werden, öffentliche Projekte müssen mit der gesamten Tool Chain auf OpenCode abgelegt werden.\n\nGleichzeitig ist eine Modernisierung in Richtung Verwaltungscloud eingeleitet worden, leider zu spät für das OZG, aber Richtlinie für zukünftige Entwicklungen.\n\nDie Entwicklung wird bereits als Angriff auf die Geschäftsmodelle und die Gewinnerwartung der Hyperscaler begriffen[2], die den Begriff der \"Digitalen Souveränität\" in mehreren Projekten zu übernehmen versuchen[3].\n\nDisclamier: Der Sprecher hat ehrenamtlich an verschiedenen Projekten mitgearbeitet, darunter im IT-Planungsrat[4],  AG Cloud und  OpenCode[5].

This attack vector leverages that many microcontrollers allow to deactivate their debug interface protection under the condition that the entire flash memory is erased first.\nThe attack suppresses this mass erase with a glitch whereby its contents are preserved and accessible through the activated debug interface.\nThis type of attack was first presented by Schink et al. at CHES 2021, but only received little attention so far.\n\nThe talk provides an introduction to this attack vector and gives a foretaste of a comprehensive analysis that will be published soon.\nThe attack will be demonstrated live on stage with an exemplary microcontroller.","original_language":"eng","persons":["marc"],"tags":["camp2023","57401","2023","Milliways",""],"view_count":1339,"promoted":false,"date":"2023-08-19T14:00:00.000+02:00","release_date":"2023-08-19T00:00:00.000+02:00","updated_at":"2026-03-30T14:45:06.533+02:00","length":1382,"duration":1382,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57401-5debf923-21bd-5831-94e6-f18406e5c727.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57401-5debf923-21bd-5831-94e6-f18406e5c727_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57401-5debf923-21bd-5831-94e6-f18406e5c727.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57401-5debf923-21bd-5831-94e6-f18406e5c727.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57401-unlock_the_door_to_my_secrets_but_don_t_forget_to_glitch","url":"https://api.media.ccc.de/public/events/5debf923-21bd-5831-94e6-f18406e5c727","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"231b147e-546c-4bdd-9906-456554dc35dd","title":"c3 NewsShow","subtitle":"Tag 0","slug":"camp2023-newsshow0","link":"https://c3voc.de","description":"Die Nullnummer der C3News Show","original_language":"deu","persons":["khaleesi"],"tags":["camp2023","88888","2023","CCC","C3VOC.tv"],"view_count":1861,"promoted":false,"date":"2023-08-14T20:08:00.000+02:00","release_date":"2023-08-15T00:00:00.000+02:00","updated_at":"2026-03-29T16:00:03.901+02:00","length":640,"duration":640,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/88888-231b147e-546c-4bdd-9906-456554dc35dd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/88888-231b147e-546c-4bdd-9906-456554dc35dd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/88888-231b147e-546c-4bdd-9906-456554dc35dd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/88888-231b147e-546c-4bdd-9906-456554dc35dd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-newsshow0","url":"https://api.media.ccc.de/public/events/231b147e-546c-4bdd-9906-456554dc35dd","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"951b84a5-f232-53ca-99ef-ba989e48af13","title":"Staatstrojaner für bereits begangene Straftaten","subtitle":null,"slug":"camp2023-57648-staatstrojaner_fuer_bereits_begangene_straftaten","link":"https://pretalx.c3voc.de/camp2023/talk/NWMSTD/","description":"Schon wieder muss Karlsruhe ran\n\nVor mehr als zehn Jahren lang ein Staatstrojaner auf dem Seziertisch des CCC.

However, the sounding rockets used in the campaigns also enable research under the influence of extreme acceleration forces as well as research in the fields of hypersonic and atmospheric physics. We like to give an overview of the basic procedures and the complexity of such a research campaign. In addition, we provide an insight into our work, which involves a lot of in-house development for hardware and software. This includes circut board design, FPGA programming as well as hardware related programming of DSP processors in assembler and C/C++. Additionally, software and hardware for wired and wireless transmission of telemetry and telecommand are developed, as well as software for operating and monitoring the service module and other components before and during flight. On a sketched flight through the atmosphere we will provide many facts and figures about all systems and components. The focus will be on the Ground Support Equipment (GSE) and the Service Module (SM) within the sounding rocket.","original_language":"eng","persons":["Martin Stoffers","Jean-Carl Keller"],"tags":["camp2023","57093","2023","Milliways",""],"view_count":275,"promoted":false,"date":"2023-08-15T16:00:00.000+02:00","release_date":"2023-08-18T00:00:00.000+02:00","updated_at":"2026-04-01T03:30:02.901+02:00","length":2380,"duration":2380,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57093-d46b1ce3-af03-564f-9496-2fbe0e1ea472.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57093-d46b1ce3-af03-564f-9496-2fbe0e1ea472_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57093-d46b1ce3-af03-564f-9496-2fbe0e1ea472.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57093-d46b1ce3-af03-564f-9496-2fbe0e1ea472.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57093-bits_and_bytes_in_microgravity","url":"https://api.media.ccc.de/public/events/d46b1ce3-af03-564f-9496-2fbe0e1ea472","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"bbfaefef-025b-59ac-ab97-8cdfbb14e60b","title":"Bid3 and CounterMilitarisim Mapping","subtitle":null,"slug":"camp2023-57099-bid3_and_countermilitarisim_mapping","link":"https://pretalx.c3voc.de/camp2023/talk/WHVPD3/","description":"Sharing experiences of two technical and educational projects that aimed to provide support for the decentralized grass movement in Sudan.\n\nshowcase of two technical-sociopolitical projects \n## Bid3a:\nThe project aims to make socio-political interventions and creatively express themselves through the courage and symbolism of manipulating and artistically hacking tech devices around.

And we actually still like that idea: A system of sticker boxes strategically placed in various assemblies, and a partnership with ChaosPost to ensure an even distribution of the stickers in the boxes. Year 1 - 36c3 - was a success and we were looking forward to doing it again. We didn‘t foresee that a year later we would be packing stickers in envelopes and sending them accross Germany and the world instead. \r\n\r\nDecember 2022 marked the third year of existence of the c3stoc remote exchange.

The talk presents the currently available models, evolution, scope of current use and presents an outlook of what might follow in the future.\n\nThe OpenMPPT development project was initiated by Freifunk in 2017 with the first design handling up to 50 Watt PV (solar) power. The intended application was to build cheap  and effective solar WiFi mesh nodes with telemetry. At the time of the project's initiation, there were no small and low-cost solar charge controllers available that included maximum power point tracking. Maximum Power Point Tracking is a technique used in solar power systems to optimize the power output from the solar panels by tracking the point where the panels can deliver the maximum amount of power. The OpenMPPT project aimed to fill this gap and provide an open, cost-effective, and repairable DIY alternative for individuals and development NGOs who look for open hardware and software solutions. Initially, the idea was not to replace or compete with more powerful closed hardware and closed software Maximum Power Point Trackers on the market. However, people and development NGOs kept asking for more power and features like the possibility of adding sensors or building irrigation systems, because they want open hardware and software solutions. The development of the Freifunk-OpenMPPTs  is following sue. The newer and expanded FF-ESP32 generations of OpenMPPT controllers are based on the ESP32 MCU by Espressif and can handle up to 400 Watt solar power. They can not only power communication nodes, but also solar powered servers in communities that live off-grid or have unstable power. However, people keep on asking for more power...","original_language":"eng","persons":["Elektra Wagenrad"],"tags":["camp2023","57058","2023","Bits \u0026 Bäume",""],"view_count":511,"promoted":false,"date":"2023-08-17T18:30:00.000+02:00","release_date":"2023-08-18T00:00:00.000+02:00","updated_at":"2026-03-14T19:45:04.996+01:00","length":1318,"duration":1318,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57058-ad70c515-8372-53e5-aa2b-2c981ef5d9d2.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57058-ad70c515-8372-53e5-aa2b-2c981ef5d9d2_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57058-ad70c515-8372-53e5-aa2b-2c981ef5d9d2.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57058-ad70c515-8372-53e5-aa2b-2c981ef5d9d2.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57058-resilient_solar_energy_autonomous_infrastructure_with_freifunk_openmppt_controllers","url":"https://api.media.ccc.de/public/events/ad70c515-8372-53e5-aa2b-2c981ef5d9d2","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"9271f4b6-bde8-5da9-9ae3-b47458fc2df2","title":"c3 NewsShow","subtitle":"Tag 1","slug":"camp2023-newsshow1","link":"https://pretalx.c3voc.de/camp2023/talk/TSDCFB/","description":"Die Themen von Tag 1","original_language":"deu","persons":[],"tags":["camp2023","57737","2023","CCC","C3VOC.tv"],"view_count":877,"promoted":false,"date":"2023-08-15T20:00:00.000+02:00","release_date":"2023-08-16T00:00:00.000+02:00","updated_at":"2025-12-09T16:30:09.534+01:00","length":875,"duration":875,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57737-9271f4b6-bde8-5da9-9ae3-b47458fc2df2.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57737-9271f4b6-bde8-5da9-9ae3-b47458fc2df2_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57737-9271f4b6-bde8-5da9-9ae3-b47458fc2df2.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57737-9271f4b6-bde8-5da9-9ae3-b47458fc2df2.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-newsshow1","url":"https://api.media.ccc.de/public/events/9271f4b6-bde8-5da9-9ae3-b47458fc2df2","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"9754dd93-088a-5927-8689-f307a2b15945","title":"Wie synthetisiert man DNA","subtitle":"","slug":"camp2023-57017-wie_synthetisiert_man_dna","link":"https://pretalx.c3voc.de/camp2023/talk/3YQS3E/","description":"Kurze Erklärung wie DNA bzw Phosphoramiditsynthese funktioniert.\r\n\r\nDNA ist der code des Lebens.

What should you even say to them? And does it even make sense to talk to that particular person, or are they so fundamentally opposed to your request that it would be a waste of time?\n\nThe tool we are developing aims to bring citizens closer to their elected representatives. It empowers users to contact Members of the European Parliament (MEPs) efficiently and with a low entry barrier. The software takes the burden away from users to understand the EU and which MEPs are best to contact on a particular issue. It also knows how to contact them, and even allows the user to call them free of charge.\n\nDearMEP is being developed as a white label solution that can be applied to any EU level decision that has to be voted upon in the plenary of the European Parliament. NGOs that campaign around an EU decision can use the software to mobilize the public efficiently with the goal to influence particular plenary votes.\n\nCurrently, the DearMEP software is tailored to address the whole European Parliament and to be used by citizens from all EU countries to contact MEPs from their countries. In this presentation, we would like to show you the current development state of this tool. We are planning to use DearMEP in the ongoing campaign against the chat control proposal. After that legislative file has concluded, we will release the software under the AGPL free software licence. During the CCCamp we will provide access to the current beta.\n\nWe would love to hear your feedback.

It is software which determines hardware's energy consumption, and for how long devices remain in use. That software design can drive environmental harm is still largely unknown to much of the population, let alone that users can already do something about it with Free Software.\n\nIn early 2023 KDE published the handbook \"Applying The Blue Angel Criteria To Free Software\", the culmination of a 21-month project funded by the German government. The handbook presents the whys, whats, and hows for certifying software as sustainable with the Blue Angel ecolabel. In this talk I will provide an overview of the environmental harm driven by software and how Free Software is well-positioned to address the issues. I will link the inherent values that come with a Free \u0026 Open Source Software license to sustainable software design, and I will present the various ways that Free Software aligns with the Blue Angel ecolabel. Finally, I will provide an overview of the current sustainability goal of KDE and the work of the KDE Eco initiative.

Since then, many things have changed. Back then we were looking into ways to use the robots' \"dumb\" sensors to spy on the user (e.g. by using the ultrasonic sensor). But all our predictions were exceeded by the reality: today's robots bring multiple cameras and microphones with them. AI is used to detect objects and rooms. But can it be trusted? Where will pictures of your cat  end up?\n\nIn this talk we will look at the security and privacy of current devices. We will show that their flaws pose a huge privacy risk and that certification of devices cannot be trusted. Not to worry, though - we will also show you how to protect yourself (and your data) from your robot friends.\n\nYou will learn on how you can get root access to current flagship models of 4 different vendors. Come with us on a journey of having fun hacking interesting devices while preventing them from breaching your privacy. We will also discuss the risks of used devices, for both old and new users.\n\nFinally, we will talk about the challenges of documenting vacuum robots and developing custom software for them. While our primary goal is to disconnect the robots from the cloud, it is also for users to repair their devices - pwning to own in a wholesome way.","original_language":"eng","persons":["Dennis Giese"],"tags":["camp2023","57158","2023","Milliways",""],"view_count":7690,"promoted":false,"date":"2023-08-18T23:00:00.000+02:00","release_date":"2023-08-19T00:00:00.000+02:00","updated_at":"2026-04-03T02:00:02.796+02:00","length":3703,"duration":3703,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57158-63d09b63-bc15-54c7-a3c4-ed631ce1a703.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57158-63d09b63-bc15-54c7-a3c4-ed631ce1a703_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57158-63d09b63-bc15-54c7-a3c4-ed631ce1a703.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57158-63d09b63-bc15-54c7-a3c4-ed631ce1a703.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57158-vacuum_robot_security_and_privacy","url":"https://api.media.ccc.de/public/events/63d09b63-bc15-54c7-a3c4-ed631ce1a703","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"65f9ce6a-cad0-5200-bcbe-850584eafc1b","title":"All cops are broadcasting","subtitle":"Obtaining the secret TETRA primitives after decades in the shadows","slug":"camp2023-57100-all_cops_are_broadcasting","link":"https://pretalx.c3voc.de/camp2023/talk/ATJMB9/","description":"In this talk we will discuss the radio jailbreaking journey that enabled us to perform the first public disclosure and security analysis of the proprietary cryptography used in TETRA (Terrestrial Trunked Radio): a European standard for trunked radio globally used by government agencies, police, prisons, emergency services and military operators. Besides governemental applications, TETRA is also widely deployed in industrial environments such as factory campuses, harbor container terminals and airports, as well as critical infrastructure such as SCADA telecontrol of oil rigs, pipelines, transportation and electric and water utilities. \n\nFor over two decades, the underlying algorithms have remained secret and bound with restrictive NDAs prohibiting public scrutiny of this highly critical technology. As such, TETRA was one of the last bastions of widely deployed secret proprietary cryptography. We will discuss in detail how we managed to obtain the primitives and remain legally at liberty to publish our findings. \n\nThis journey has involved reverse-engineering and exploiting multiple zero-day vulnerabilities in the highly popular Motorola MTM5x00 TETRA radio and its TI OMAP-L138 trusted execution environment (TEE) and covers everything from side-channel attacks on DSPs, through writing decompilers headache-inducing DSP architectures, all the way to exploiting ROM vulnerabilities in the Texas Instruments TEE.","original_language":"eng","persons":["Jos Wetzels","Carlo Meijer","Wouter Bokslag"],"tags":["camp2023","57100","2023","Milliways",""],"view_count":6321,"promoted":false,"date":"2023-08-17T15:00:00.000+02:00","release_date":"2023-08-18T00:00:00.000+02:00","updated_at":"2026-03-25T22:15:07.426+01:00","length":2849,"duration":2849,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57100-65f9ce6a-cad0-5200-bcbe-850584eafc1b.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57100-65f9ce6a-cad0-5200-bcbe-850584eafc1b_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57100-65f9ce6a-cad0-5200-bcbe-850584eafc1b.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57100-65f9ce6a-cad0-5200-bcbe-850584eafc1b.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57100-all_cops_are_broadcasting","url":"https://api.media.ccc.de/public/events/65f9ce6a-cad0-5200-bcbe-850584eafc1b","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"33d2dc3f-3ab6-551f-bf5c-fc3f8f6fd8b6","title":"How to grow a flow3r","subtitle":"","slug":"camp2023-57559-how_to_grow_a_flow3r","link":"https://pretalx.c3voc.de/camp2023/talk/C3BVMM/","description":"Do you want your flow3r to blossom?

The negotiations for the digital identity and digital euro proposals have the potential to for tectonic change in the digital age. This talk will provide basic info, explain a bit how the EU works and try to mobilise more people to join the debate.\n\nThe EU is in the midst of a reform that could drastically change our right to anonymity online. The European Digital Identity Wallet aims to bring a legally binding way to identify citizens online and offline with governments and companies. The system also allows to prove attributes about a person like their age, driver licence or covid/vaccination status. The EU also mandates large online platforms like Facebook, YouTube or Amazon to support this system to login to their services. The risk for discrimination, over-identification and surveillance of all areas of life is unprecedented. Well over two years into the negotiations we give an update about the status of the reform, what to expect and how to engage. \n\nAdditionally, this session will also give an introduction about the EU legislative proposal for a digital Euro and how it could impact our financial privacy. The goal of this session is to make EU policy more accessible for the audience and help the digital rights community to express their positions in the EU policy arena.

It is indeed, quite easy to remotely command all kind of devices from our smartphones, with a single click. \n\nThese technologies are also very efficient to help compensate certain handicaps but they have limits when it regards people whose handicap – or combination thereof - prevents them from manipulating a smartphone, reading a screen or using vocal commands.\n\nThe good news is that it is not necessary to reinvent the wheel as alternative ways to interact with our technological environment, already exist. \n\nThese solutions however, often stay inaccessible because their usage is judged too complex, their implementation considered time-consuming but mostly because of their (outrageous) price. \n\nAs a patient, it can be very frustrating to be shut down from these possibilities to improve our quality of life and become more independent.\n\nThat’s why I turned all my hopes to open-source hardware and tools, right after my I soldered my first TV-B-Gone, about 10 years ago  :)\n\nI’ve been working on this “Impossible Interface” ever since. I can only describe it as a universal remote control that can also interact with non connected physical objects like the buttons of a lift or a simple light switch.\n\nThe name Impossible Interface was chosen because of the amount of time I was told it was impossible to build such a device, especially for less than 500 euros but ...\n\nBootchoo II, my latest prototype basically is a Arduino compatible 5 Axis Robot Arm (https://www.adeept.com/robotic-arm-uno_p0118.html) to which I just added a Bluetooth module and I am currently testing several ways of controls it. \n\nIdeally, commanding that little bot could be personalized depending on the type of handicap(s) that needs to be compensated. \n\nI am currently focusing on patients with low finger mobility, testing different sizes of joysticks as well as other “alternative remote” possibilities such as the ones offered by the MCH2022 badge and the Flipper Zero.\n\nAs for the reason why I submitting this small talk – even though I am very shy – is because it is precisely not about me. Being as autonomous as possible is a need we all share and it should not be considered a luxury. \n\nI’ve mostly worked alone on this project but I got a lot of support from the Hacking Health Besançon association (https://hacking-health.org/fr/besancon-fr/), since I submitted this project during their latest edition.\n\nI’ll also admit that it is also time to ask for help to make this open-source assistive robot, safer, stronger and smarter and I can’t think of a better place to share my humble experiments, than at CCCamp.","original_language":"eng","persons":["Melinux"],"tags":["camp2023","57259","2023","Milliways",""],"view_count":197,"promoted":false,"date":"2023-08-19T11:00:00.000+02:00","release_date":"2023-08-19T00:00:00.000+02:00","updated_at":"2026-02-11T21:30:12.520+01:00","length":1710,"duration":1710,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57259-9d309fe3-d4e0-5823-9de5-301bfcd51fe6.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57259-9d309fe3-d4e0-5823-9de5-301bfcd51fe6_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57259-9d309fe3-d4e0-5823-9de5-301bfcd51fe6.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57259-9d309fe3-d4e0-5823-9de5-301bfcd51fe6.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57259-hack_my_handicap","url":"https://api.media.ccc.de/public/events/9d309fe3-d4e0-5823-9de5-301bfcd51fe6","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"b02513ed-e36c-5671-929a-7503aedb3d04","title":"PID Loops Control All the Things","subtitle":"","slug":"camp2023-57111-pid_loops_control_all_the_things","link":"https://pretalx.c3voc.de/camp2023/talk/3HXEEC/","description":"Hidden inside basically every physical machine that needs precise control, PID loops are running the show.

I would love to look at projects that people are making and give some advice, and just have a chat about accessibility and visual impairments.","original_language":"eng","persons":["AJ Hamilton"],"tags":["camp2023","57230","2023","Bits \u0026 Bäume",""],"view_count":216,"promoted":false,"date":"2023-08-15T16:00:00.000+02:00","release_date":"2023-08-16T00:00:00.000+02:00","updated_at":"2026-03-07T03:00:03.377+01:00","length":392,"duration":392,"thumb_url":"https://static.media.ccc.de/media/conferences/camp2023/57230-fc5f078e-bfc5-58c0-9252-e64f81a41fc2.jpg","poster_url":"https://static.media.ccc.de/media/conferences/camp2023/57230-fc5f078e-bfc5-58c0-9252-e64f81a41fc2_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/camp2023/57230-fc5f078e-bfc5-58c0-9252-e64f81a41fc2.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/camp2023/57230-fc5f078e-bfc5-58c0-9252-e64f81a41fc2.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/camp2023-57230-a_visually_impaired_perspective_on_technology","url":"https://api.media.ccc.de/public/events/fc5f078e-bfc5-58c0-9252-e64f81a41fc2","conference_title":"Chaos Communication Camp 2023","conference_url":"https://api.media.ccc.de/public/conferences/camp2023","related":[]},{"guid":"f6e37df6-e754-5fa5-8e6f-816485419c39","title":"Chaos Science Slam","subtitle":null,"slug":"camp2023-57535-chaos_science_slam","link":"https://pretalx.c3voc.de/camp2023/talk/RTMHGU/","description":"Der Science Slam auf dem Camp - Wir vermissen die Zukunft, also sind wir sie suchen gegangen\n\nSo trug es sich zu vor nicht allzu langer Zeit, dass eine (Franca) auszog um die Welt zu retten und zwar mit Wissenschaftskommunikation. Sie steht regelmäßig mit anderen auf der Bühne und erklärt ihre Wissenschaft leicht verständlich bei Science Slams. Noch nie von Slam gehört? Wissenschaftlys haben im Wettbewerb gegeneinander 10 Minuten Zeit ein Forschungsthema unterhaltsam auf die Bühne zu bringen. Das Publikum entscheidet wer es am besten gemacht hat und die Person bekommt einen Preis.\nUnd was hat das Ganze jetzt mit Weltrettung zu tun? Nun ja, Weltrettung gestaltet sich schwierig alleine, deswegen suchte Franca 11 weitere Wissenschaftlys und alle zusammen haben ein Buch geschrieben, das sich „Weltrettung braucht Wissenschaft“ nennt. Ein Buch in dem es um nichts weniger geht als die drängenden Fragen unserer Zeit zu beantworten – zumindest in Teilen. 12 wissenschaftliche Themenbereiche fassen kurzweilig zusammen wie unsere Erde vielleicht doch noch zu retten ist, wenn wir wissenschaftlichen Erkenntnissen folgen. \n4 der Autorys kommen zum Camp. Freut Euch auf Simon McGowan und die Antwort auf die Frage: Liegt die Lösung des Plastikproblems darin nur noch Bioplastik zu verwenden? Franca Parianen bringt uns näher - Wie beeinflussen Hormone unsere Wahrnehmung und wie die Umwelt unsere Hormone? Sarah Hiltner fragt und beantwortet - Bringt gendern Menschen um, oder hat es vielleicht das Potenzial Menschenleben zu retten?
