How to take your first steps in threat modelling, or an opportunity to extend and/or reorient an existing threat modelling programme. Systems created by humans will contain flaws. In order to shine a light on these flaws, you can use a technique called threat modelling. There are hundreds if not thousands of different threat modelling methods that can be used to tease apart the structure of a system in search for security issues. In this talk, we will cover the key principles behind these methods, enabling anyone to study and mend the architecture of a system. In covering the basics, we will also critically reflect on the direction of much research and practice, sketching the relevance of threat modelling for addressing contemporary challenges and highlighting the role that you can play in making a security impact. *As preparation for or follow-up of this talk, [see this recorded training](https://archive.org/details/getting_started_with_threat_modelling).* *The recorded training can be watched either before or after the live talk. The talk takes a more reflective and critical look at threat modelling, diving into its underlying history and the current state of research, while also providing a space for Q&A and the sharing of experiences.* about this event: https://events.ccc.de/congress/2023/hub/event/getting-started-with-threat-modelling/

This talk presents QEMU-iOS, an open-source emulator of legacy Apple devices. I outline the process of emulating an iPod Touch 2G, discussing the technical challenges and reverse engineering methodologies applied. The talk starts with an overview of the project's goals and then outlines the reverse engineering process, utilizing tools like Ghidra for disassembling the Apple bootloader, XNU kernel, and other binaries. Then, I describe QEMU, a popular framework for emulation, and show how essential iPod Touch peripherals such as the touchscreen, storage, and display have been implemented. Finally, this talk touches upon the implications of open-sourcing this project, its contribution to the emulation and reverse engineering landscape, and its potential for future efforts to emulate newer Apple devices. During the past decades, Apple has created iconic devices that have found a place in the hands and hearts of millions of people around the world. As many of these devices have become obsolete, the importance of preserving their digital essence has grown. The emulation of legacy devices with software allows enthusiasts and researchers to explore and interact with them long after the original hardware has ceased to be available. Emulation, therefore, allows the digital preservation of obsolete hardware, ensuring these devices are accessible to future generations. This talk describes a multi-year project named QEMU-iOS that lays the groundwork for emulating legacy Apple devices. In particular, we have focussed on emulating the iPod Touch 2G using QEMU, an open-source framework for hardware emulation. Yet, even emulating an old device with a few peripherals compared to contemporary devices is challenging since the specifications and inner workings of many peripherals are proprietary and completely undocumented. The talk first describes the overall project motivation, goals, and vision. Then, I will discuss the reverse engineering process where multiple undocumented peripherals of the iPod Touch have been analyzed to understand and replicate their specifications in software. A key talking point will be the working of essential peripherals, including the cryptographic engines, the LCD, the Flash memory controller, various hardware communication protocols, the touchscreen driver, and other peripherals. The talk will also detail the booting procedure of the iPod Touch, elaborating on the emulation of the iBoot bootloader, the XNU kernel, and the Springboard application in iOS. Getting the boot chain up and running required extensive debugging efforts using powerful reverse engineering tools such as Ghidra to disassemble and analyze all essential binaries in the boot procedure. After outlining the reverse engineering process, I will present the implementation of QEMU-iOS, which entails a functional emulator that boots the iOS operating system, renders the display, and responds to touches on the screen. The final part of this talk will touch upon the implications of open-sourcing this project, its contribution to the broader emulation and reverse engineering landscape, and the potential it holds for future efforts in emulating other legacy Apple devices, as well as the viability of emulating newer devices with advanced peripherals such as the Neural Engine. I will also discuss existing approaches, highlight where QEMU-iOS differs, and summarize the lessons learned while emulating these devices. This talk is designed for a wide range of people, whether you are new to reverse engineering and emulation or have experience in these fields. The goal is to explain the technical challenges faced during this project in a way that's easy for beginners to understand while also providing more in-depth insights I discovered while working on QEMU-iOS. Through this talk, the aim is not only to share the technical knowledge gained from this project but also to explore the merits of emulation and reverse engineering to keep old devices alive. about this event: https://events.ccc.de/congress/2023/hub/event/breathing_life_into_legacy_an_open-source_emulator_of_legacy_apple_devices/

While more and more hackerspaces have been founded in the recent years, there are many different topics that are being discussed at the same time: AI, 3D printing, Arduino, social and political questions, and lots more. Where are the hacks though? Things are happening, and with this talk, we want to talk about them and call for exchange. At Chaospott in Essen, we have developed rich tools to interact with and inspect hardware, enabling people to bring their gadgets to new life and run their own code, be it on TV boxes, network cameras, or appliances of various kinds. In other words, should a cloud service go down or unmaintained software get compromised, we revive what would otherwise be bricks. about this event: https://events.ccc.de/congress/2023/hub/event/bringing-the-hack-back-into-the-chaos/

The work titled Buffered Daemons is a sound performance that attempts to explore the concepts of translation and non-local interaction in the sound realm. It does so by playing with the idiosyncrasies of audio representation/playback and mobilises them through the creation of an expanded musical situation. In the piece, three different containers of sound are presented: acoustic(Sound diffusion in the architecture), digital (computer based sound algorithms) and analogue (electromagnetic tape and analog processing). This containers, or buffers, are then being intertwined by the performer creating thus sonic textures that interplay with the resonances of the space. The strategy for the sound performance is to articulate a metaphor of a circular-buffer, a data structure used in Computer Science, to the idea brought upon in Derrida’s interview with Ornette Coleman, in which Improvisation practice in music is understood as a reading in which the borders between reading and writing are obfuscated. The work is inspired by the concept of daemon and non-locality explored by Timothy Morton in his reading of Plato’s Ion as well as Ursula K. Le Guin’s The Carrier Bag Theory of Fiction. about this event: https://events.ccc.de/congress/2023/hub/event/buffered_daemons/

Your phone’s internal communication contains precious data. It can be analyzed to detect fake base stations used in cellular attacks. For that, we reverse-engineered a proprietary communication channel between the phone’s OS and modem. Connecting to cellular networks around the world is a highly complex task. iPhones contain a baseband chip (also referred to as a modem) for that purpose. It communicates via a high-level interface with the smartphone’s application processor running iOS. So far, Apple hasn’t been able to build such basebands in-house. Instead, starting from the iPhone 12, they exclusively rely on Qualcomm basebands. Qualcomm’s basebands use a proprietary protocol for external communication, the Qualcomm MSM Interface. We reverse-engineered its iOS implementation and built a framework to extract the protocol’s packet structures from iOS firmware. Our iOS Wireshark dissector uses these packet structures and enables us to monitor the flow of packets between the baseband and iOS. This allows us to gain new insights into the iPhone’s wireless communication infrastructure, including its satellite connectivity. Our tooling also provides a novel way to directly interact with the baseband chip in jailbroken iPhones, bypassing iOS and unlocking hidden capabilities of the baseband. Fake or Rouge base stations can be set up by individuals using readily available software-defined radios. Adversaries can utilize them to capture IMSIs of nearby smartphones, track their location, or exploit vulnerable basebands. iPhone users usually don’t notice such attacks, and there are (almost) no protection mechanisms implemented in iOS. During our research, we discovered Apple’s internal cell location database, which is intended for determining approximate positions. Our CellGuard iOS app combines this database with the QMI analysis framework to monitor various parameters of connected cells, verify their authenticity, and alert users in case there’s suspicious activity. The app even works on non-jailbroken iPhones. We evaluated the app in a lab environment with SDRs and real-world tests since February 2023 and are steadily improving it for a release next year. about this event: https://events.ccc.de/congress/2023/hub/event/what_your_phone_won_t_tell_you/

Let's talk ten year old tech! The myo armband was once a really strange way to control a computer, and then became a way to do fine-grained myomuscular electrical detection research. This is a talk about how to hook a myo to a Raspberry Pi 3B+ in 2023, and from there how to have the armband communicate over serial to other devices. We choose to use it to control a Programmable Air system for pneumatic control of muscular robots. Let's talk ten year old tech! The Myo armband from Thalmic Labs was once a really strange way to control a computer, and then became a pretty good way to do fine-grained myomuscular electrical detection research for prosthetics. These processes usually have a high cost or involve less-portable computing systems. In order to make a robotic effect that can be deployed apparently independently, it's more interesting to have a low-cost, encapsulated system. In this talk we'll walk through what it takes in 2023 to have a Thalmic Myo armband talk to a Raspberry Pi 3B+ using Python. We'll provide a demonstration of a pneumatic robot based on the Programmable Air system controlled over serial using the armband. The goal of this project is to have access to strong mechanical advantage without the compromises of servos or stepper motors, and with some of the organic feel possible with air or water systems. about this event: https://events.ccc.de/congress/2023/hub/event/encapsulated-electromyography-with-myo-and-raspi/

3,4 Tonnen schwer, 4,3 Meter lang, Material: Stahl, Farbe: Orange und der Fahrzeugtyp ist „Sporttauchboot”. Vom Fund eines Drucktanks bis zum ersten Tauchgang auf den Grund eines Tagebausees – wir erzählen von unseren größten Herausforderungen sowie Fehlschlägen. Wir laden euch ein zu einem technischen Beratungsgespräch für alle, die schonmal mit dem Gedanken gespielt haben, ein U-Boot zu bauen. Die einzelnen Systeme eines U-Boots sind nicht kompliziert. Aber die Schwierigkeit liegt in der Summe der Einzelsysteme, die auf engem Raum im Zusammenspiel sicher funktionieren müssen. Der Fokus des Vortrags liegt neben unserer kurzweiligen Geschichte auf den technischen Schwierigkeiten, zu denen sich in der Literatur wenig findet oder wegen derer es nicht gleich auf Anhieb funktioniert hat. Damit ihr, falls ihr ähnliches plant, einen besseren Start habt und von unseren Fehlern profitieren könnt. Was gibt es bei der Wahl eines geeigneten Drucktanks zu beachten? Wie lässt sich eine wasserdichte Luke konstruieren? Drahtlose Unterwasserkommunikation mittels Ultraschall? Wie bauen wir Redundanz in die Systeme ein? Wie werden wir das CO2 los, um nicht zu ersticken? Warum sind auf einmal Risse in den Scheiben? Was tun, wenn nichts mehr geht? Und was, wenn dann auch noch die Polizei kommt? In dem Vortrag geht es nicht um Probleme anderer kaputter U-Boote. Wir werden das Titan-Desaster mit maximal einer Folie behandeln.

Mainframe, Oldenburg's Hackerspace, needed a wireless door lock solution. We do not trust vendors advertising promises about the device security and had a closer look. Attend this talk for a presentation about an unusual variant of lock picking, which does not involve any wrenches, hooks or half-diamond picks. Instead the used tools are a software defined radio, PIC programmer and some self-developed software to gain access without using the original key remote control. If you had fun watching the [Hörmann BiSecur talk at 34C3](https://media.ccc.de/v/34c3-9029-uncovering_vulnerabilities_in_hoermann_bisecur), this talk is for you! If you haven't watched it, it is highly recommended to catch up on it before attending this talk. While it is about a different product from a different vendor, there are many parallels and it can be seen as a sequel talk. The plan for this talk is to first have a look at the radio signals from the door lock using a SDR. After making sense of the used message protocol, the hardware is analyzed to understand how it works and how to get access to the used micro-controllers (PIC18LF45K80 & PIC16LF1829). In the next step, the firmware from the read-protected PIC microcontroller is extracted by extending the existing PIC attacks. Last but not least the results will be demonstrated. about this event: https://events.ccc.de/congress/2023/hub/event/unlocked_picing_a_wireless_door_access_system/

Wie umgehen mit der politischen Verzweiflung? Was tun, wenn der Staat keine der Krisen wirklich noch bekämpfen kann, sondern nur neue erzeugt? Reicht es noch, für Transparenz zu kämpfen? Das Beste aus dem letzten Jahr – nein, aus den letzten vier Jahren! – FragDenStaat und Informationsfreiheit. Wir plaudern aus dem Nähkästchen von verlorenen Klagen gegen Frontex über Nazis im EU-Parlament bis zu den Pimmelgate-Akten und darüber, wie aus einer kleinen Recherche die größte Gefangenenbefreiung der deutschen Geschichte wurde. Freut Euch unter anderem auf die besten Auskunfts-Klagen der vergangenen Jahre, laufende Strafverfahren gegen FragDenStaat, missglückte Geldübergaben an die EU-Grenzpolizei und die Frage, ob das alles irgendwas bringt. Euch erwartet außerdem ein Best-Of des Freiheitsfonds, der in zwei Jahren mehr als 900 Menschen aus dem Gefängnis befreit und eine Gesetzesänderung angestoßen hat. Vielleicht wird auch gesungen. about this event: https://events.ccc.de/congress/2023/hub/event/heimlich-manover/

The aim of this talk is to critically analyse the use of digital technology in the current context of global ecological injustice and the collapse of ecosystems. But how can we strive for and promote a sustainable, just and democratic digital future? The challenges are huge and include the digital world's hunger for energy as well as the exploitative global practices of tech companies or the discussion of the current AI sustainability hype. But which digital tools make sense, which do not and how can we achieve global social emancipation from self-destructive structures and towards ecological sustainability and a and a just world? about this event: https://events.ccc.de/congress/2023/hub/event/on_digitalisation_sustainability_climate_justice/

Die zwölf Jahre seit der Selbstenttarnung des NSU haben gezeigt, dass auf den Staat bei der Aufklärung und Aufarbeitung von rechtem Terror kein Verlass ist. Deshalb haben Betroffene von rechter Gewalt, Antifaschist\*innen und Zivilgesellschaft diese Aufgabe wieder und wieder selbst in die Hand genommen. Die daraus gewonnenen Analysen, die Aufklärung und die entstandenen solidarischen Netzwerke sind vielfältiger, als sich viele am Anfang vorgestellt haben. Doch wir wollen fragen: Was können nächste Schritte sein? Wie können wir rechten Terror verhindern? Das bundesweite antifaschistische Bündnis NSU-Watch hat im Sommer 2023 sein Buch „Aufklären und Einmischen. Der NSU-Komplex und der Münchener Prozess“ in der erweiterten Neuauflage herausgebracht. Es gibt einen Überblick über die bisherige Aufarbeitung des NSU-Komplexes. Auf dieser Grundlage wollen Vortrag und Lesung fragen: Was können nächste Schritte sein? Wie können wir rechten Terror verhindern? Die Antworten sind vielfältig und warten teilweise noch darauf, entdeckt zu werden. Und trotzdem bleibt die Gefahr rechten Terrors hoch, auch weil auf staatlicher, behördlicher und gesellschaftlicher Seite Konsequenzen noch ausstehen. Doch wir wissen bereits jetzt genug, um rechtem Terror aktiv entgegenzuwirken. about this event: https://events.ccc.de/congress/2023/hub/event/gemeinsam_gegen_rechten_terror_aber_wie/

How do you capture a video from an 1989's Game Boy without modding the original hardware? With an adapter cartridge that spies on the memory bus! Let's talk about how to reconstruct the Game Boy's memory state, emulate its graphics unit and then encode the image into an MJPEG stream for anyone to use as a USB video class device. In realtime. On an rp2040 microcontroller. The original goal of the open source project "GB Interceptor" was to capture gameplay for one specific game: Tetris. In order to live stream a Tetris tournaments from the contestant's personal Game Boys, the idea was to create an adapter that goes between the Game Boy and the game module to analyze the communication on the memory bus and reconstruct the game state. It turns out that it is actually possible to reconstruct the entire memory state of almost any game and in fact create an rp2040-based adapter that acts as a USB video class device offering the on-screen game footage in realtime. Players can simply put this adapter into their Game Boy and use it like a webcam without additional drivers or knowledge. An essential aspect of this concept is that the Game Boy basically runs all of its code directly from the ROM module, which makes it possible to directly follow the program counter of its 8bit CPU regardless of how the code branches. An image can then be recreated by emulating the graphics unit (PPU). However, there are many edge cases like interrupts, data from registers that are not visible on the bus, the link cable, DMA operations, synchronization of CPU and PPU, game bugs and even bugs in the Game Boy hardware itself. In this talk I will show how all this is done just on an rp2040 with spare cycles to encode everything as a 60fps MJPEG stream. I will shine a light on the edge cases - those that were solved and those that might just be unsolvable with this approach. And I will take you on a sightseeing tour through the 8bit hell that drives our iconic handheld from 1989. about this event: https://events.ccc.de/congress/2023/hub/event/reconstructing_game_footage_from_a_game_boy_s_memory_bus/

Von Simone Herpich (Balkonsolar eV) und Dr. Juliane Borchert (Fraunhofer Institut für Solare Energiesysteme) lasse ich mir alles (so viel wie geht) über Solarenergie erzählen. about this event: https://events.ccc.de/congress/2023/hub/event/erklr-ma-solarenergie/

I have previously given talks about security principles and approaches like Least Privilege, TCB Minimization, and Self Sandboxing. The most frequent feedback has been "I don't know how to apply this in practice". So, in this talk, I will show how I applied those principles in a real-world software project: a CRUD web app. My blog. I introduced dangerous attack surface on purpose so I could some day give a talk about how to apply these techniques to reduce risk. This is that talk. I will also introduce the concept of append-only data storage. The end goal of this talk is to show how much more security you can achieve if you don't take an existing architecture and try to sprinkle security over it, but you make architectural decisions with security in mind. This is rarely done in practice because there is a fundamental disagreement between security and software engineering. Security is about limiting what can be done with the software, while software engineering is about not limiting what can be done with the software. My goal with this talk is to show what kind of security gains are possible architecturally. You, too, can sleep soundly at night. Even if the software is written in C. Even if you have bad ACLs or a buffer overflow in the software. about this event: https://events.ccc.de/congress/2023/hub/event/writing_secure_software/

In the original Hacker Ethics, Steven Levy stated that "you can create art and beauty on a computer". That was 40 years ago, creating art and beauty is one thing, but how do you maintain or develop it as a gallery, archive or museum? You know all about CI/CD and deploying to "the cloud"? Well, let me show you how to deploy to a museum or art space. Important note: this talk is not about NFTs. The preservation and presentation of software/computer-based art in museums presents unique challenges in the contemporary landscape. One prominent issue is the ephemeral nature of digital media, which includes websites, games, software and virtual reality art. Unlike traditional art forms, these works often rely on rapidly evolving technologies, making them vulnerable to obsolescence. Museums are faced with the task of preserving and restoring media art in a way that not only preserves the original intent of the artist, but also ensures accessibility for future audiences. Another significant challenge is the dynamic and interactive nature of many media artworks. Unlike static paintings or sculptures, digital artworks often require specific hardware, software or immersive environments to be experienced. Museums need to invest in both the technological infrastructure and the expertise to recreate these conditions and provide visitors with an authentic encounter with the artwork. In this talk we want to look at some solutions from the perspective of software developers who are motivated not only to preserve and present digital media art, but also to develop it with contemporary software development strategies. about this event: https://events.ccc.de/congress/2023/hub/event/devops_but_for_artworks_in_museums/

In diesem Vortrag wollen wir auf die letzten knapp drei Jahre Kampf gegen die Chatkontrolle zurückblicken. Ein Kampf, der genauso droht zu einem Wiedergänger zu werden wie die Vorratsdatenspeicherung. Wir waren auf eine harte Auseinandersetzung um Überwachung und sichere Kommunikation vorbereitet. Als Patrick 2020 angefangen, hat uns vor dem, was da kommt, zu warnen, haben wir nicht erwartet, dass es sich zu einer Tragödie entwickeln würde, in der es nicht um Kinderschutz oder Überwachung geht. Sondern um eine Kommission, der jedes Mittel recht ist. Und Korruption und Lobbyskandal. Über die Chatkontrolle wurde in den letzten zwei Jahren viel geredet – die problematischen Inhalte des Gesetzes kommen den meisten von uns wahrscheinlich zu den Ohren heraus. Aber letztlich geht es um nicht weniger als einen historischen Kampf um Ende-zu-Ende-Verschlüsselung. Auf dem Tisch liegt das Thema aber schon deutlich länger. Wir wollen zurückblicken auf die Ursprünge und Kernpunkte des Gesetzesvorschlags. Und dann zusammen mit dem Publikum noch einmal die unüberschaubaren Wege gehen, die die Arbeit an diesem Gesetzesentwurf genommen hat. Aus der Perspektive von Deutschlands oberstem Datenschützer (Ulrich Kelber), dem Abgeordneten des Europäischen Parlamanets (Patrick Breyer) und der digitalen Zivilgesellschaft (khaleesi) erzählen wir die bisherige Geschichte der Chatkontrolle. Wenn ihr dachtet, ihr hättet alles zur Chatkontrolle gehört, bereitet euch auf eine absurde Tragödie vor, die ihr Ende noch nicht gefunden hat. Trotz des Erfolgs im EU-Parlament haben wir noch lange nicht gewonnen. Denn alles hängt im und am Rat, dessen Position könnte im Trilog alles zunichte machen was wir hart erarbeitet haben. Und auch die Europawahlen stehen vor der Tür und damit kann sich nochmal alles ändern. Nicht fertige Gesetze werden in der EU in der nächste Legislaturperiode einfach weiterverhandelt. Um die Chatkontrolle endgültig zu stoppen, darf keine EU-Abgeordnete durch den Wahlkampf kommen, ohne sich klar zum Schutz von Verschlüsselung zu bekennen. about this event: https://events.ccc.de/congress/2023/hub/event/chatkontrolle_-_es_ist_noch_nicht_vorbei/

Wir sollten uns alle mehr Zeit für Mental Health Care nehmen, also mehr für unsere psychische Gesundheit tun. Ich zeige Euch, mit welchen einfachen Schritten das auch zuhause geht... Und wie und wo Ihr professionelle Hilfe dabei findet, wenn Ihr sie braucht - und warum die klassischen Therapiemethoden bei neurodiversen Menschen oft nicht so gut funktionieren. Der erste Teil des Talks klärt, was Mental Health eigentlich ist, wer die braucht (Spoiler: wir alle) und wie sich mit Mental Health Care Resilienz aufbauen lässt. Wir müssen aber auch darüber sprechen, was dieses "Home" eigentlich ist - und ob Ihr das als wichtigsten Mental Health - Skill erkannt habt und nutzt. Ich stelle Euch einfache Skills für Zuhause und unterwegs vor, wie ich sie in der DBT kennen- und schätzen gelernt habe. Skills auch für Menschen ohne psychische Diagnosen - damit das auch so bleibt. Und im dritten Teil reden wir über die Situation, dass und wenn Ihr doch mal Unterstützung für die Psyche braucht: Wie und wo findet Ihr Unterstützung? Ambulante oder stationäre Therapie - oder ganz ungewöhnliche Art der Therapie (Wawuschel-Style)? Und warum brauchen neurodiverse Menschen andere, leider in unserem Gesundheitssystem nicht vertretene, Therapien? Schickt mir gerne vor dem Talk Eure Themen und Fragen zu Mental Health Care zuhause mit, damit ich die einbauen kann. :) about this event: https://events.ccc.de/congress/2023/hub/event/try-mental-health-care-zuhause/

What is Sápmi? And who are the Sami people? Why is their land threatened by the so-called Green Transition? Why is Europe's largest data centre being built on their land? We would like to try to answer these questions and explain in detail why "our green transition" is a threat to the land and rights of the Sami people. We will also discuss the so-called green server infrastructure in Sápmi for example the largest data centre in Europe (by Facebook). We are from the Decolonise Sápmi info tour through Germany and not Sámi ourselves. Our talk is based on presentations given by Sámi people during our tour. Sápmi is located in northern Europe and refers to the land of the Sámi people. Over time it has been colonized by Sweden, Norway, Finland and Russia. As a result, the Sámi have been subjected to various forms of oppression and discrimination by these countries to this day. Sápmi and Sápmi’s colonial history are presented. Current forms of oppression are also addressed. An important role is played by “green capitalism,” a form of capitalism in which oppression is advanced under the guise of climate protection. Some examples include: Dams that disrupt reindeer migration routes and flood sacred Sámi sites, or wind turbines that are widely avoided by reindeer. Of course, the lectures will also address the problems that mines pose for the Sámi. A topic which was discussed lately with the discussion around the rare earths found in the so-called Sweden also here in Germany. Furthermore, the problems caused by the still occurring clear-cutting in the area of the Sámi and the resulting loss of biodiversity are explained. What resistance has there been in recent years against this capitalist destruction and (green) colonialism? What is the current situation in Sápmi and what does the future look like? about this event: https://events.ccc.de/congress/2023/hub/event/ecocide_and_green_colonialism_in_sapmi/

The Solar System has had 8 planets ever since Pluto was excluded in 2006. This has made a lot of people very angry and been widely regarded as a bad move. But did you know Neptune was discovered as the 12th planet? Or that, 80 years before Star Trek, astronomers seriously suspected a planet called Vulcan near the Sun? This talk will take you through centuries of struggling with the question: Do you even planet?! In antiquity, scientists counted the 7 classical planets: the Moon, Mercury, Venus, the Sun, Mars, Jupiter and Saturn – but their model of the universe was wrong. Two thousand years later, a new model was introduced. It was less wrong, and it brought the number of planets down to 6: Mercury, Venus, Earth, Mars, Jupiter, Saturn. Since then, it's been a roller coaster ride of planet discoveries and dismissals. In this talk, we stagger through the smoke and mirrors of scientific history. We meet old friends like Uranus and Neptune, forgotten lovers like Ceres, Psyche and Eros, fallen celebrities like Pluto, regicidal interlopers like Eris and Makemake as well as mysterious strangers like Vulcan, Planet X and Planet Nine. Find out how science has been tricked by its own vanity, been hampered by too little (or too much!) imagination, and how human drama can make a soap opera out of a question as simple as: How Many Planets in Our Solar System? about this event: https://events.ccc.de/congress/2023/hub/event/how_many_planets_in_our_solar_system_glad_you_asked/

Why do some people stay fit and healthy easier than others, even when following the same health advice? Why does the same medication work well in one person, but not in another? Some of our individuality in these regards may trace to which bacteria we carry in the soil of our intestinal gardens. In this talk, drawing on work by my own research lab at the Charité and on that by our collaborators and rivals elsewhere in the world, I outline what we know, what we speculate, and what obstacles remain in the way of widespread adoption of personalized health prevention through microbiome sequencing. Despite our best efforts of finding the perfect regimen of diet, exercise and medication to keep any person fit and healthy, outcomes for different people vary widely for all of these measures, even when we comply with them fully. Some of this traces to our individual genetics, which remains difficult to change, but another source of variation in responses may come from differences between our gut microbiomes. Human bodies are not sterile, and our skin, our mucosal surfaces and, in particular, our intestines are home to many more bacteria than there are human cells in our bodies, representing hundreds of different species in each person. These microbial ecosystems, or microbiomes, are found in all animals and have coevolved with their hosts. Therefore we rely on commensal ("friendly") bacteria for many functions, including breaking down nutrients, converting some medications into their active forms, producing certain crucial compounds for us from our diet, and helping our immune systems mature and remain tuned. The microbiota also contains temporary visitors and both transient and resident opportunistic pathogens, often kept in check by the immune system and by the commensals, but sometimes escaping such control to multiply and cause disease. Human gut microbiomes begin establishing at birth and evolve over a lifetime, but remain quite stable within each person throughout adulthood unless something serious like repeated antibiotic cures disrupt them. However, they can differ quite substantially between individuals as well as between populations, reflecting factors such as nutrition and environmental exposures. It has been proposed, and to a degree already demonstrated, that differences between individuals in which gut bacteria they harbour may underlie differences in their susceptibility to disease, their resilience to stressors, and their responses to environmental stimuli. Thus the variation in responses to the same lifestyle between different people may reflect their gut microbiomes. This would open up several venues of personalized medicine, lifestyle advice and nutrition. Choice of medications, diets or interventions could be selected according to a person's specific microbiome to be most effective. It might also be possible to potentiate such interventions by altering the gut microbiome in different ways, such as through antibiotics, probiotics, nutrition or through microbiome transplantation from another person. Alternately put, by adapting the microbiome to a lifestyle intervention, and/or adapting a lifestyle intervention to the microbiome, we may be able to optimize how a given person can seek and achieve fitness and health. In this talk, I will outline what we know on these topics so far, especially from studies using large-scale microbial (meta-)genome DNA sequencing. In this talk I will draw on work by my own lab at the Charité in Berlin, as well as that of our colleagues, rivals and collaborators elsewhere in the world. I will give examples of known gut microbial modulation of human responses to the external environment and introduce the most common strategies both for researching such effects and for their leverage as health-promoting tools.

Über die letzten vier Jahre sind in der Nautosphäre um den Chaos Computer Club, Deutschland, Europa und der Welt aufregende, irritierende, bemerkenswerte und empörenswerte Dinge passiert, bei deren Einordnung wir gerne helfend zur Seite stehen wollen.
