description: Illuminated Ice blockes are melting. The ice/light/sound installation is an ongoing project which started 2009. In my talk I want to give an introduction to my motivation, the global ice melting. The installation brings this abstract knowledge as a sensual experience to the people. The integration of sensors and electronics generates sound and data. I will show visualizations and numbers of the impact of the climate change on the global ice amount. The installation was shown in many collaborations, contexts, galleries, festivals, etc. Since a few years I started to work with sensors to count the drops and create sound by sensors and electronics. I will give an overview about my experiences and future ideas. I invite artists and data scientists to take part in further developments in sound, light, data and digital participation. Find source code, data and instructions on github. To get an impression about the installation watch the videos below After the talk will be live video streaming.

Building Blocks of Decentralization

uk: Комп'ютерні науки

description: Much of our time online continues to be spent in centralized silos. A wide range of projects continue to chip away at building decentralized alternatives, but it's fair to say that decentralized platforms continue to play catch up. This talk looks at a few of the key problems underlying many schemes for decentralization, and reflect on how different projects are tackling them and what remains challenging. In particular decentralized platforms grapple not only with how to efficiently scale, how to balance resiliency and capacity, how to name and discover content and users, but also have to consider privacy and security. In 2020 we've seen increased adoption of both federated (matrix, activity pub) and decentralized (ssb, ipfs, cryptocurrencies-writ-large) platforms. Lots of decentralized engineering has been happening this year. The Interplanetary Filesystem restructured its DHT to get content discovery times below 5 seconds. Matrix grew to more than 2,500 federated servers, and got a contract with the German education system. Planetary.social extended the Secure Scuttlebutt gossip protocol to mobile. The crypto-currency community has settled on some strategies for parallel computation to address scaling pains, and are continuing to work on building systems for decentralized governance and organizations. On the flip side, there remain plenty of big questions these systems are hitting. You can't just keep scaling a DHT without the overhead of connection setups and metadata overwhelming performance. Consistency remains computationally expensive at scale, and decentralization of power and wealth are not solvable with engineering alone.

description: Im Zuge des diesjährigen rC3 Events soll der Konflikt um die Region Berg-Karabach in diesem Vortrag aufgearbeitet werden. Der seit 26 Jahren andauernder Konflikt entwickelte sich im September diesen Jahres in einen zwischenstaatlichen Krieg zwischen Armenien und Aserbaidschan, der drastische Schäden verursachte. Es befinden sich über 75.000 Menschen aus den Kriegsgebieten auf der Flucht, ohne Heimat und ohne Eigentum, und eine humanitäre Katastrophe wird mit jedem Tag wahrscheinlicher. Woran es dem Konflikt fehlt ist klar: Transparenz und Sichtbarkeit. Der Vortrag ist in drei Hauptteile gegliedert. Im ersten Schritt werden die involvierten Akteure und ihre Positionen analysiert. Danach sollen technische Entwicklungen Armeniens und Aserbaidschans sowie der Kriegsverlauf evaluiert werden, um in einem dritten Teil realistische Lösungsansätze zu betrachten, die auf eine langfristige Deeskalation des Konfliktes abzielen. Die übergeordnete Frage lautet, welchen Einfluss der Konflikt um Berg-Karabach auf die internationale Ordnung hat. Berg-Karabach zwischen Krieg und Frieden Der Konflikt zwischen Armenien und Aserbaidschan im Südkaukasus von Larissa Willamowski Am 27. September 2020 eskalierten Kampfhandlungen armenischer und aserbaidschanischer Truppen in Südkaukasus innerhalb weniger Tage zu einem zwischenstaatlichen Krieg (Stöber 2020). Dieser Ausbruch kommt erschreckend, wenn auch nicht überraschend, zumal sich die Beziehungen beider Staaten in den letzten Jahren zunehmend verschlechtert haben (Gasparyan 2019). Sechs Wochen hielten die blutigen Auseinandersetzungen an, bis in der Nacht vom 9. auf den 10. November unter der Vermittlung des russischen Präsidenten Vladimir Putin bei einem zweiten Versuch ein neuer und, bis heute, weitestgehend eingehaltener Waffenstillstand ausgehandelt werden konnte (Stöber 2020). Im Zuge des diesjährigen rC3 möchte ich den wiederaufgeflammten Konflikt um die Region Berg-Karabach in einem Vortrag aufarbeiten. Ich argumentiere, dass mehr Sichtbarkeit und Transparenz für diesen Konflikt geschaffen werden muss, was sich erstens durch die Involvierung von Regionalmächten, wie der Türkei, und Großmächten, allem voran Russlands, begründet (Abushov 2019). Auch die Rolle des Westens soll beleuchtet werden, denn daraus folgt, dass dieser regionale Konflikt eben doch auf die internationale Ebene rückwirkt. Zweitens ist die Erhältlichkeit von Informationen vor Ort sehr eingeschränkt. Deshalb wird durch den Vortrag versucht, durch journalistische Beiträge einen Mehrwert für die Informationsbeschaffung zu leisten. Das soll der Vermischung der Narrativen der Akteure entgegenwirken. Drittens beschuldigen sich die Konfliktparteien des Bruchs des humanitären Völkerrechts durch den Beschuss ziviler Ziele. Das Schweigen der internationalen Gemeinschaft zu diesen Vorwürfen ist zu laut, um nicht auf diesen Punkt aufmerksam zu machen. Viertens stellt sich nach einer, aus armenischer Sicht, zerschmetternden Niederlage Armeniens die Frage, wie es nach dem Krieg weitergehen soll. Was passiert mit den mehr als 75.000 Menschen vor Ort, die aufgrund des Krieges ihre Heimat verloren haben und sich auf der Flucht befinden? Realistische Lösungsansätze die auf eine Vermeidung einer Re-eskalation des Konflikts abzielen und die die katastrophalen Umstände vor Ort in den Vordergrund rücken, müssen öffentlich diskutiert werden. Ursprünge des Konfliktes: Der Bruch der UdSSR führte zu gravierenden Strukturänderungen im internationalen System, dessen Folgen der Region des Südkaukasus bis heute nicht erspart bleiben. 1991 eskalierten bewaffnete Auseinandersetzungen zwischen Armenien und Aserbaidschan in einem dreijährigen Krieg. Konfliktgegenstand ist damals so wie heute die Region um Berg-Karabach. Russland schaffte es in seiner Rolle als OSCE Mediator die Konfliktparteien im Mai 1994 zu einem Waffenstillstandsabkommen zu bewegen (Abushov 2019). Dieses Abkommen stellt einen wichtigen Moment dar, denn seit jeher konnte selbst nach 26 Jahren intensiver Friedensverhandlungen unter der Aufsicht der Troika Gruppe (RU, FR, USA) nicht mehr garantiert werden, als die bloße Weiterführung eines Waffenstillstandes. Basierend auf dem fortwährenden „no war – no peace“ Status warnen Forscher*innen seit Jahren vor einem erneuten Aufflammen eines bewaffneten Konfliktes (Özkan 2008). Diese instabile Grundlage ist einer der vielen Gründe, weshalb zunächst im Juli und später im September 2020 bewaffnete Gefechte wiederaufflammten. Die Gegenstände des Konfliktes sind nach wie vor territoriale und ethnische Streitigkeiten um Berg-Karabach und angrenzende Gebiete (Stöber 2020). Aufbau des Vortrags: 1. Akteurs Identifizierung: Who is fighting whom? Um zu verstehen wieso der Konflikt erneut in einem Krieg endete, werden zunächst die Positionen der Hauptakteure analysiert. Im Mittelpunkt stehen dabei die Rivalität zwischen Aserbaidschan und Armenien und die Position Berg-Karabachs als de-facto Staat ohne internationale Anerkennung. In einem zweiten Schritt stelle ich mir die Frage, welche Rolle und Interessen internationale Akteure wie Russland, die Türkei und der Westen im Konflikt verfolgen. Auch internationale Organisationen wie die OSZE und die Minsk Gruppe spielen in diesem Zusammenhang eine wichtige Rolle. 2. Technische Entwicklungen und Kriegsverlauf In diesem Teil wird diskutiert, wie (technischen) Kapazitäten der Kriegsparteien den Verlauf des Konfliktes beeinflusst haben. Zunächst werden die Kapazitäten beider Staaten gegenübergestellt. Außerdem evaluiere ich den Zusammenhang der jeweiligen Verteidigungsbudgets der Staaten und der wirtschaftlichen Performance der Staaten. In einem zweiten Schritt kann bei einem genauen Blick auf den Kriegsverlauf gezeigt werden, welche Technologien entscheidende Auswirkungen auf den Kriegsverlauf hatten. Armenien und Aserbaidschan beschuldigen sich gegenseitig des Bruchs humanitären Völkerrechts durch den Beschuss ziviler Ziele. Durch die vorangegangene Analyse soll geklärt werden, inwiefern die Vorwürfe bestätigt werden können. 3. Neue Friedensverhandlungen Wenn Armenien und Aserbaidschan bis heute unter internationaler Vermittlung nicht in der Lage waren das Waffenstillstandsabkommen auf ein längerfristiges Friedensabkommen auszuweiten, wie hoch ist dann heute die Wahrscheinlichkeit, dass dieses Ziel umgesetzt wird? Dieser Teil bettet die analysierten Positionen und Narrativen der Kriegsparteien in den Kontext der internationalen Friedensvermittlungen. Ist ein Friedensabkommen dieses Mal wahrscheinlicher als vor 16 Jahren? Welche Aspekte soll ein zufriedenstellendes Abkommen beinhalten? Literaturverzeichnis: Abushov, Kavus (2019).

description: Museen digitalisieren ihre Sammlungen, Dokumentationen und die Vermittlung. Das geht auf verschiedenen Ebenen zu schnell, denn eigentlich wird ihre gesellschaftliche Rolle gerade stark hinterfragt. Nicht nur am Umgang mit kolonialen Erwerbungen entzünden sich Debatten. Der Vortrag beschreibt wie die aktuelle Auseinandersetzung um die gesellschaftliche Rolle von Museen auch die Digitalisierung stärker in den Blick nehmen muss. Museen sind jetzt digital. Die kolonialen Erwerbungen sind jetzt 3d-Scans. Die rassistischen Klassifizierungen sind jetzt Daten-Ontologien. Die sexistischen Gemälde sind jetzt Bilddateien. Die Kurator*innen sind jetzt Daten-Management. Die Social Media Abteilung sind jetzt Vermittler*innen. Und im Lockdown findet die Führung in Instagram-Stories und Youtube-Videos statt. Die Liste an ethischen Bedenken sollte lang sein. Doch die digitalen Museen walzen munter voran, allein in Berlin müssen ja 5.000.000 Objekte der staatlichen Museen in die Datenbank, 5.000 wurden schon vor 10 Jahren zu Google Arts & Culture gegeben. Dazu werden VR und AI Technologien des Forschens und Vermittelns gehyped. Insbesondere die Behauptung des "geteilten Kulturerbes" wird jedoch in den Sharingökonomien und in den Datensilos zur Farce - meist regiert auch im digitalen Raum der Besitzanspruch und die Deutungshoheit des "Universalmuseums". Der Vortrag umreißt das Problem und macht Vorschläge, wie die bestehende Vorstellung vom digitalen Museum hinterfragt, entschleunigt und mit Gegenentwürfen konfrontiert werden kann.

description: Every day, surveillance companies attack mobile networks, attempting to track the location of mobile phone users. We will analyze, using real-life data, these surveillance companies’ tactics and show the different ways that users are tracked in the wild over 2G, 3G and 4G networks. For 5G, we describe the critical functions and information elements in the core network that might be targeted by these attackers. Mobile core signaling networks have been known to have exploitable vulnerabilities for several years. However very little information has been presented on whether these vulnerabilities are being exploited in real-life or not, and if so, how it is being done. This presentation will give first-hand information about how location tracking – the most common form of mobile signaling attack - is being done over multiple types of mobile networks in the wild today. We will start with briefly introducing mobile telecom networks, their known security flaws and how surveillance companies exploit these flaws. Surveillance companies are success oriented and have a toolbox which they use for location tracking of mobile phone users, which is the most common attack. Based on real-life experiences we will describe what “tools” we see in the wild and how they work. We will also describe how attackers optimize attacks based on the target network and technology, and how attacks have changed over time since some mobile operators have begun to put in place protections. We will also show a visualization of how these attacks can happen. Finally, we will make a projection for 5G core networks, and how they will also be targeted by surveillance companies as they are deployed globally over the next few years.

description: Oftentimes, we read about the state of digital rights on the Global North and their challenges, but we hear little from the Global South. What is, then, the state of digital rights on the Global South and, specially, in Latin America? Are those rights threatened in the same way that they are in the Global North? Do those rights apply in the same way? On this talk, we will explore these questions. We will touch upon the history of digital censorship in Latin America, how it has evolved, and how surveillance in the region is increasing. Perhaps one of the biggest challenges that we have as a community is the fact that we hear little from the perspectives from other regions of the world that are often consuming the technology and ideas produced from the Global North. This talk will aim to bring the Latin American perspective to the table: to talk about the state of digital rights in the region, about the challenges facing towards a digital sovereignty, about the state of digital rights from a legal and political perspective, and more.

description: 2020 was and still is an eventful year - pandemic, protests, orange men, you name it. This talk is a comprehensive overview about yet another tumult: the protests that occured in Bulgaria in 2020, months of demonstrations against an European Union member state government that were largely unacknowledged in the rest of the EU - from the perspective of an expat and an involved small scale activist on the fringe. The goal is to convey to some extent my experience and acquired updated knowledge I made while trying to figure out what exactly was going on as the protests erupted in my home country, who were the actors, what do they want, what interests do they represent and what is the current state. This will include a brief historical background, introduction to the main political and criminal actors, societal factors, the story of how a national flag on a beach in Rossenez started it all, how the protests developed, how the national & international press reacted and finally the EU's position or the lack of such. To top it off we will see/hear some first hand impressions of a protester on the ground. In slightly more detail, the talk will consist of: 1. A brief introduction: - a brief historical perspective and context up to 2020, - the ups & downs that formed the poorest country in the EU, - its evergoing struggle with corruption and crime deeply interwined in the state itself. 2. An outline of the current landscape as shown with - some statistics backed up by official data, - current state of education, health, economics sectors - the current ruling party GERB and Bulgarian sun king Boyko Borrissov - other present and past key political players. 3. A summary and a timeline of the protests, - why and how they began - an overview of the highlights, such as police brutality, press (non)freedom, state suppression etc., - why are the people protesting, - what protesting fractions were there, (by no means the full picture) and what they seek 4. Appearances of and reactions to the protests, - digital means of these protests (Facebook, Twitter) - some problems with the protests (racism, sexism), - a brief live impression from an on-the-ground protester. 5. Role of the EU, its institutions and MEPs, its silence/involvement, - EPP, its chairman & MEPs shielding the corruption - EU politicians showing solidarity and drawing attention to the problem, - the current outcome.

Infinity: Confronting the Really Big

uk: Комп'ютерні науки

description: Infinitely large quantities can arise in mathematics, physics, game theory and philosophy. Those need to be handled with care if one wants to avoid paradoxes. This is a beginner's introduction to taming inf. This will be a guided tour to a variety of occurrences of infinite quantities when counting, sorting, playing games, philosophising about arrows and turtles and when computing scattering of elementary particles. In each situation, I will explain some tools to control these infinities and how to get sensible answers to sensible questions. We will see really big sets, understand how to add 1 to infinity and how to take infinity to the infinite power, play games that are worth infinite amounts, how to add 1+2+3+ and so on to obtain -1/12 and why it is often easier to pretend something is infinite when it actually is not. Along the way, we will learn from Aristotle, Cantor, Hilbert, Feynman, Conway and what they contributed to this infinitely interesting subject. They audience should be willing to bend their mind but will not need anything but a bit of high-school mathematics.

Rage Against The Machine Learning

uk: Комп'ютерні науки

description: This talk explains why audits are a useful method to ensure that machine learning systems operate in the interest of the public. Scripts to perform such audits are released and explained to empower civic hackers. The large majority of videos watched by YouTube's two billion monthly users is selected by a machine learning (ML) system. So far, little is known about why a particular video is recommended by the system. This is problematic since research suggests that YouTube's recommendation system is enacting important biases, e.g. preferring popular content or spreading fake news and disinformation. At the same time, more and more platforms like Spotify, Netflix, or TikTok are employing such systems. This talk shows how audits can be used to take the power back and to ensure that ML-based systems act in the interest of the public. Audits are a ‘systematic review or assessment of something’ (Oxford Dictionaries). The talk demonstrates how a bot can be used to collect recommendations and how these recommendations can be analyzed to identify systematic biases. For this, a sock puppet audit conducted in the aftermath of the 2018 Chemnitz protests for political topics in Germany is used as an example. The talk argues that YouTube's recommendation system has become an important broadcaster on its own. By German law, this would require the system to give important political, ideological, and social groups adequate opportunity to express themselves in the broadcasted program of the service. The preliminary results presented in the talk indicate that this may not be the case. YouTube's ML-based system is recommending increasingly popular but topically unrelated videos. The talk releases a set of scripts that can be used to audit YouTube and other platforms. The talk also outlines a research agenda for civic hackers to monitor recommendations, encouraging them to use audits as a method to examine media bias. The talk motivates the audience to organize crowdsourced and collaborative audits.

Most people who build websites tend to do that because they want other people to use those websites. Sadly it is rather common that little to no effort is put into making that possible for disabled users. In this talk I want to show that it actually isn’t too difficult to build more accessible web sites by "getting the low hanging fruit" first. Generally most of the stuff shown here can be implemented in an existing website without throwing away the existing design or doing a whole rewrite.

description: This talk will be about FPMON, a browser extension that shows you where, when and which browser fingerprinting method is applied against you. You can use it to test your favorite websites and check your own services for 3rd-party fingerprinting scripts. It can also be used to test various browser privacy tools. Tracking users is a ubiquitous practice in the web today. User activity is recorded on a large scale and analyzed by various actors to create personalized products, forecast future behavior, and prevent online fraud. While so far HTTP cookies have been the weapon of choice, new and more pervasive techniques such as browser fingerprinting are gaining traction. Hence, in this talk, we describe how users can be empowered against fingerprinting by showing them when, how, and who is tracking them using JavaScript fingerprinting. To this end, we conduct a systematic analysis of various fingerprinting tools. Based on this analysis, we design and develop FPMON: a light-weight and comprehensive fingerprinting monitor that measures and rates JavaScript fingerprinting activity on any given website in real-time. Using FPMON, we evaluate the 10k most popular websites to i) study the pervasiveness of JavaScript fingerprinting; ii) review the latest fingerprinting countermeasures; and iii) identify the major networks that foster the use of fingerprinting. Our evaluations reveal that i) fingerprinters are present on many popular websites with sensitive contents (finance, news, NGOs, health, etc.); ii) they run without user consent and subvert current privacy regulations; and iii) most countermeasures can not sufficiently protect users.

Very Pwnable Network (VPN)

uk: Комп'ютерні науки

description: Virtual Pwn Networks (VPNs) add a network layer that should provide privacy and security. The privacy of VPNs clearly depends on their endpoint, thus, many companies run their own instances. We demonstrate that VPNs can be insecure nonetheless, as the users connecting to a company's VPN typically requires proprietary client software on their systems. These proprietary clients lack security, as we show based on the Cisco AnyConnect client for Linux and iOS. This research starts with a weird series of crashes on Jiska's iPhone. Due to her ongoing paranoia, she decided to use a VPN, and because she had to trust her university's network anyway, she decided to use her university's Cisco VPN service. Obviously, this did not go well, and soon she had crash logs with memory accesses to invalid addresses, because these addresses were representing Strings?! These errors only occurred when she had bad network connectivity and no debugging enabled, so nobody was able to reproduce them. Either way, to start analyzing Cisco AnyConnect security, the more accessible Linux client was the first option. Gerbert did a detailed analysis and documented how this client works, since there was no documentation at all and users basically install a black box on their system. The application is by no means just a VPN client anymore. In addition to VPN connections, the application offers a number of special features like auto updating, file deployment and host assessment. The AnyConnect Linux client is even able to execute arbitrary scripts provided by the server, thus, the user needs to ultimately trust the AnyConnect provider. Even if this trust assumption holds true, the client is so complex that various attack vectors become possible. Gerbert found two vulnerabilities resulting in three attack scenarios. One of the issues was fixed without being assigned a CVE, the other one got CVE-2020-3556. Matthias continued with the iOS client, which is even harder to analyze than the closed-source Linux client. Since many Linux features are not available on iOS and the client has a completely different design, the previously found attacks do not apply. However, he will show the general architecture of this iOS Cisco AnyConnect Network Extension.

Failed Empathy

uk: Комп'ютерні науки

description: Gute Autismusrepresentation in Medien ist wichtig, aber auch schwer. In diesem Vortrag möchten wir uns angucken, wie autistische Menschen in Medien dargestellt werden und, was wir selbst an schlechten Beispielen über Empathie lernen können. Autistische Menschen haben in ihrem Leben oft keine realen Vorbilder, weil es einfach so wenige von uns gibt. Umso wichtiger ist es, dass es Geschichten, Filmen und Spielen Vorbilder gibt, in denen wir uns wieder erkennen können. Doch leider werden viele dieser Geschichten eben nicht von autistischen Menschen geschrieben. So entstehen Zerrbilder, die nicht nur verletzende Klischees verbreiten, sondern auch autistischen Wesen einen völlig falschen Eindruck vermitteln, was normales und gesundes Verhalten ist. In diesem Vortrag werden wir uns auch ansehen, wie die öffentlich rechtlichen Autismus mit dieser Verantwortung und erklären, warum sie trotz ernsthaft bemerkenswerten Bemühungen doch mit "Ella schön" eine sehr problematische Serie produziert haben. Wir werden weniger ausführlich auch andere Werke kritisieren und vor allem zeigen, wer es besser gemacht hat.

Dieser Vortrag erzählt die Geschichte der Entstehung aus einer Innenperspektive. Angefangen bei einer wissenschaftlichen Idee, dass automatische Kontaktnachverfolgung auch datensparsam ohne Standortdaten klappen könnte, entstand im Frühjahr 2020 eine bemerkenswerte Dynamik, die zur Entwicklung der CWA führte. Hier soll es weniger um technische Fragen zu Bluetooth gehen, als vielmehr um die Hintergründe zu Design und Entwicklung. Von der Zusammenarbeit mit Apple und Google, über Befürchtungen zu staatlicher Souveränität auf Mobilgeräten, über sanften Druck des CCC, bis hin zu aktiver Einmischung der Bundesregierung gibt es viel zu erzählen.

How to survive in spacecraft

uk: Комп'ютерні науки

description: If you pop out into space, you die. No oxygen to breathe, no ambient pressure makes your bodily fluids boil, UV radiation burns your skin to a crisp. It's not a good place to be for humans. So in order to survive, you need to bring a number of things along, commonly called the "life support system". This talk explains how this works! How do oxygen generators and CO_2 scrubbers work? Do you need to heat or cool your craft? If you eat beans and fart a lot, do you ever get rid of the smell? Can you just fill your spacecraft with plants and live off them? This talk goes through historic, present and future ways that life support is managed in spacecraft, spacesuits and future planetary outposts. It also explains why you have to breathe your own pee on the International Space Station. (This is the logical followup to the two previous, german talks about how to fly spaceships and how to build them, from the GulaschProgrammierNacht 13 and 16)

Alexa, who else is listening?

description: Sex, private conversations, daily routines - smart assistants likes Alexa and Siri know often more about you, than you may think. This talk shows what metadata reveals about your private life. It investigates how private conversations, wrongly transmitted, are also analyzed by human transcribers, hired by big tech. This talk investigates smart assistants like Alexa and Siri. For half a year we collected in an experiment our own Alexa voice data, analyzed and investigated it. We deeply looked into accidental triggers. These are words and sentences which wake Alexa and Siri up, even if they shouldn’t. Every time for a couple of seconds, audio data, is transmitted to Amazon or Apple. And as it is widely known, real people are listening to that. Sex, children, employers talking to their bosses – we met whistleblowers and transcribers, who have worked for the big tech companies. They improve the artificial intelligence of smart speakers for the price of private eavesdropping. The analyzed metadata revealed even more how deep smart speakers intrude your private sphere – and that in the end Amazon, Apple and Google will know (nearly) everything about you.

Why we need to reinvent media - and how

uk: Комп'ютерні науки

description: Today's (social) media is broken. We are building a democratic, decentralized alternative. To do that, we are fundamentally reinventing the business model behind a media platform. The goal is to end privacy invasions, advertisement, paywalls, and unaccountable media corporations - and to help everyone to focus on transforming their lives and society at large. **What?** Social media originally promised the democratization of media. In today's polarized world of disinformation we know it did not work out. The main reason for that is the business model of advertisement. In this model, our attention and behaviour are modifiable commodities, sold to the highest bidders. As we have seen, today's centralized platforms and their ad-based model are misused heavily to damage democracy, incite hate and fuel conflict. We are being driven into polarization, losing our common ground. So, it is past time we end this race to the bottom before it is too late. **How?** The existing alternatives -e.g. paywalls- don't work. Primarily, because they contradict the open knowledge model of the Internet, they fragment the web, are non-inclusive and intransparent. We need to think outside the box by fundamentally rearranging the incentive model and building an open, free and democratic alternative. That is what we are working on. We are building a media-crowdfiltering-system with different stages. People can access all the content for free at the earlier stages. As a small service in return, they filter the noise for the later stages by curating the content. The people at the later stages pay a small amount for the priviledge of seeing only the highest-quality content and not having to go through all the noise themselves. There is one big catch: The people at the later stages don't pay the small amount to the platform but in fact to the **individual pieces of content that changed their life**. Their money goes to the **creator of this piece of content** and **everyone who signalled it for them at the earlier stages**. At the same time it acts as a vote, further filtering out less good content. This reward concept makes it a self-sustaining system with no need for outside investment. And at the same time leads to crowdfiltering towards truly life-changing content. The incentives are changed so that everyone involved has the quality of content in mind, and not the click rate. This is only a brief description. **The talk will explain our approach in more detail**.

Visual dynamics of healthy aging

uk: Комп'ютерні науки

description: This presentation provides some empirical insights (dynamic statistical figures and 3d models) into the question of how kinship and family shape health trajectories. This interdisciplinary study uses descriptive elements of sequence analysis and regression analysis based on the high-dimensional balanced panel data from the 7 waves of the Survey of Health, Ageing and Retirement in Europe (SHARE-project.org, waves 1-7) released between 2004 and 2017. The transformation of the traditional family has overlapped with population aging. Social and demographic challenges have increased the diversity of the life course and aging trajectories. Relatively little research has examined the interplay between changing families and health dynamics. However, family relations shape the determinants of health, such as care settings. How kin and family structures impact gender differences in functional health over the second half of life?

If each individual is to keep its individuality and autonomy in its daily choices, it must be protected and given effective tools to defend its own autonomy. Recognizing that human life has been digitally extended must question ourselves on what makes us human today. Should personal data be considered as component of the person, rather than objects that can be owned by whoever collects that data? Should our digital integrity be protected? If each human person already has a right to physical and mental integrity (Swiss Constitution article 10 al.2), shouldn’t it have a right to digital integrity? This talk will introduce this new legal concept, its possible implications for data protection and how this concept could be introduced in the current legal framework.

description: "Listen to the science" is relatively easy when it comes to mitigating climate change, we need to stop burning fossil fuels. However, climate change is already here, in this talk I'll focus on what the science has to say on extreme weather and losses and damages. For a long time it has not been possible to make the - arguably for the day to day life of most people crucial link – from anthropogenic climate change and global warming to individual weather and climate-related events with confidence but this has changed in recent years. Quantifying and establishing the link between individual weather events, that often lead to large damages, has been the focus of the emerging science of extreme event attribution. Even if a comprehensive inventory of the impacts of climate change today is impossible, event attribution allows us to understand better what climate change means. Arguably even more importantly, disentangling predictable drivers of an extreme event like anthropogenic climate change, from natural variability and changes in vulnerability and exposure will allow a better understanding of where risks are coming from and in turn how they can be addressed. Extreme events open a window to address the problem of exposure and vulnerability. Scientific evidence of the importance of different drivers is essential to avoid playing blame games and allows instead for a well-informed debate about addressing risk.

Adopting the Noise Key Exchange in Tox

uk: Комп'ютерні науки

description: Tox [0] is a free and open source peer-to-peer instant messaging protocol and implementation, that aims to provide secure messaging. It’s intended as an end-to-end encrypted (E2EE) and distributed Skype replacement. Tox’ cryptography is based on the NaCl library from Daniel J. Bernstein [1]. The cryptographic primitives for the key exchange (X25519), authentication (Poly1305) and symmetric encryption (XSalsa20) are state of the art peer-reviewed algorithms. Unfortunately Tox’ authenticated key exchange (AKE) during Tox’ cryptographic handshake is a "home-brewed" cryptographic protocol (remember: do not roll your own crypto!) and is known to be vulnerable to key compromise impersonation (KCI) attacks [2]. In this talk we will show why this vulnerability is challenging to exploit in practice. However, we will also present a fix to this vulnerability by designing and implementing a new cryptographic Tox handshake with formally-verified security properties. KCI is a vulnerability of AKE protocols, which in this case could enable an attacker, who compromised the static long-term private X25519 [3] key of a Tox user Alice, to impersonate any other Tox user (with certain assumptions) to Alice ("reverse impersonation"). Furthermore, this would enable this attacker to perform a Man-in-the-Middle (MitM) attack and therefore tampering of exchanged messages. X25519 key pairs, that are necessary for the distributed hash table (DHT), make an actual KCI-attack more complex as suggested in the initial vulnerability report by Jason A. Donenfeld. The Noise Protocol Framework [4] from Trevor Perrin (co-author of Signal [5]) was used to design a new KCI-resistant Tox’ handshake. The Noise Protocol Framework is intended to use by protocol designers to create secure channel protocols based on Diffie-Hellman (DH) key agreement. Noise provides different handshake patterns for different use cases. These patterns define a sequence of DH operations to calculate a shared symmetric session key. The security properties of these patterns are formally verified. These security properties can include forward secrecy, identity hiding and most notably KCI-resistance. A handshake pattern is instantiated by DH functions, cipher functions and hash functions to give a concrete Noise protocol. Such Noise protocols are already used in some applications, like WireGuard VPN [6]. The Noise protocol used in Tox is Noise_IK_25519_ChaChaPoly_SHA512. The Noise-C library from Rhys Weatherley [7] was used to implement the new AKE in c-toxcore [8]. The implementation is currently in proof-of-concept state and will be further improved. In future work, instead of using the Noise-C library, which supports most of Noise’ handshake patterns and all cryptographic primitives, only the Noise protocol used in the Tox handshake will be implemented in c-toxcore. This will remove Noise-C as a dependency (i.e the only other dependency is NaCl/libsodium), reduce source lines of code and therefore reduce the attack surface. Noise also provides functions to further improve security, like session re-keying, which could also be adopted in Tox. Terminology in context of Tox: * Tox is the name of the protocol in general * The implementation of Tox is toxcore - a network library (see [8]) * The clients (using toxcore) have specific names (e.g. qTox [9]) ____ * Full Master Thesis: https://pub.fh-campuswien.ac.at/obvfcwhsacc/content/titleinfo/5430137 * [0] https://tox.chat/ * [1] https://nacl.cr.yp.to/ * [2] https://github.com/TokTok/c-toxcore/issues/426 * [3] https://ed25519.cr.yp.to/ * [4] https://noiseprotocol.org/ * [5] https://signal.org/docs/ * [6] https://www.wireguard.com/ * [7] https://rweather.github.io/noise-c/index.html * [8] https://github.com/TokTok/c-toxcore * [9] https://github.com/qTox/qTox

description: From the AFL++ team comes a talk about the core concepts of fuzzing, novel fuzzing research, a library, and parts of fuzzing that can be edited and swapped out. In this talk, we present the theory, building blocks and ideas behind our evolution to AFL++, a powerful and flexible new fuzzer design. Instead of a command line tool one-trick-pony, security researchers will be able to build the perfect fuzzer for their target, and extend parts of their fuzzer with their own code. After dealing with the monolithic C codebase inherited from AFL for over a year, we learned how to build a better toolsuite from scratch, as a library, with reusable components and easily maintainable code. The design of the framework follows a clear division of fuzz testing concepts into interconnected entities. Like LEGO bricks, each part of the fuzzer can be swapped out with other implementations, and behavior. The first prototype, libAFL, was developed as one of the AFL++ Google Summer of Code projects in C. After seeing that the concepts work in practice, we are now creating a powerful fuzzing framework in Rust. This talk discusses these concepts and how they relate to existing fuzzers at the state of the art. Thanks to its flexibility, the library can be used to reimplement a wide variety of fuzzers. We discuss how we tackle common problems like scaling between cores, and embedding the fuzzer directly into the target for maximum speed. The building blocks discussed in this talk will be the engine under the hood of a future AFL++ release, and, hopefully, your next custom-build fuzzer. Download

description: The EU Commission is using education politics and digitization to increase European Integration and move beyond ERASMUS+. Current trends in European Higher Education Policy include the European University Initiative, Micro-Credentials, Virtual Exchange, Internationalization at Home or the Student eCard. We want to show you how these ideas and concepts are interconnected and discuss the pros and cons of the current developements as they can lead to more democracy and more cooperation as well as to more isolation. As the common notion of an "ever closer union" has failed with Brexit, new ways are considered to increase Europeanization. Although the idea is as old as the Union itself a new concept has taken center stage promising to create greater cohesion within the union: the European University. In November 2017, the European Commission went public with plans to start a so-called "Sorbonne Process" in order to create an EU-wide common educational area (EEA) in which mutual recognition of qualifications, mobility and improvement of language acquisition are tackled in unison. These efforts include the introduction of European University Alliances (EUAs) and a Student eCard. The latter aims to improve the exchange of bureaucratic information between universities in the EU. Other concepts like Micro-credentials, Virtual Exchange and Internationalization at Home have later been added to these new efforts by the Commission. The EUAs have become important testing fields and launch pads for these ideas and student representatives are increasingly worried about their implications for the future of education. But while these new instruments can fundamentally change the nature of higher education, there are also reasons for optimism. From the beginning on some of the EUAs have included democratic student involvement in all their structures. We hope that these early efforts can lead to new forms of student representation, teaching young students democratic cooperation on a European level and helping them represent their interests even better. This talk will introduce you to current trends in European Higher Education Policy with special attention on how digitization is used to further strategic goals of the EU Commission. The implementation of the European Universities will not be without conflict and conflicting positions: Micro-Credentials, European Student eCards and new democratic structures can lead into a benevolent as well as a malign future. Our talk aims to cover all relevant dimensions and offer you the opportunity to discuss with us the problems at hand.

description: Die Geschichte einer etwas ungewöhnlichen Hausbesetzung im schwäbischen Reutlingen (kein Witz!) und was sich daraus bisher entwickelt hat - zusammen mit einer Idee, wie selbstbestimmtes Wohnen aussehen kann und meinen bisherigen Erfahrungen, was auf unserem Weg hilfreich war. Wir befinden uns im Jahre 2019 n.Chr. Der ganze Wohnungsmarkt im Ländle wird von gierigen Vermieter*innen kontrolliert... Im ganzen Ländle? Nein! Die aus unbeugsamen Reutlinger*innen bestehende 'Crew' hört nicht auf, dem Wucher Widerstand zu leisten. Und das Leben ist nicht leicht für die GWG und ihre Verbündeten... So begann im Mai letzten Jahres die Geschichte der Hausbesetzung der K39 in Reutlingen - und weil sowas in der schwäbischen Provinz (nimmt man mal die typischen Uni-Städte Tübingen und Freiburg aus) wirklich ungewöhnlich ist, war ich natürlich neugierig genug, da mal vorbeizuschauen... Zwischenzeitlich ist viel passiert. Was genau passiert ist, wie es (hoffentlich) weitergeht, aber auch was das Mietshäuser Syndikat ist und was ich persönlich auf dem bisherigen Weg gelernt habe, soll Inhalt des Talks sein.

Die rosarote Brille des Fediverse

uk: Комп'ютерні науки

description: Vor 4 Jahren erblickte Mastodon das Licht der Welt. Schnell bekam das Fediverse dadurch neuen Aufwind. Nun ist es Zeit in dieser Beziehung die rosarote Brille abzulegen. Welche Autorität haben große Instanzen gegenüber kleinen? Sind wir vor den Gefahren großer gated Plattformen gewappnet? Wollen wir die Platzhirsche der sozialen Netzwerke wirklich aufbrechen? In diesem Vortrag möchte ich aufzeigen, wie wir das Fediverse gestalten können, um für die vor uns liegenden Fallen bereit zu sein. Die Hoffnungen um das Fediverse sind groß. Viele erwarten sich immer wieder, dass es die digitale Öffentlichkeit nachhaltig verändern wird. Manche meinen gar es würde reichen die großen Plattformen wie Facebook und Twitter dazu zu zwingen mit dem Fediverse zu föderieren. Doch sind wir überhaupt bereit, dass Millionen neue User ins Fediverse geschwemmt werden? Mastodon konnte zahlreichen Communities ein eigenes Zuhause geben. Doch wie gehen wir damit um, wenn sich große Instanzen dazu entscheiden die Föderation wieder abzuschalten und ihre Nutzer*innen bei ihnen einzusperren? Die Probleme, die mit einem wachsenden Netzwerk einhergehen, sind vielfältig, aber nicht unlösbar. Aber solange wir die metaphorische rosarote Brille aufgesetzt haben, neigen wir dazu, die Lösungen nur in der föderierten Struktur des Fediversums zu sehen. Unweigerlich ignorieren wir auch welche Probleme von den dominierenden Plattformen einfach nur übernommen werden und welche Probleme die Eigenheiten dieser Struktur selbst mit sich bringen. Nur wenn wir darüber reden, beginnen wir auch über die Lösungen zu sprechen.

description: Models, as well as the explanations and predictions they produce, are on everyone's minds these days, due to the climate crisis and the Corona pandemic. But how do these models work? How do they relate to experiments and data? Why and how can we trust them and what are their limitations? As part of the omega tau podcast, I have asked these questions of dozens of scientists and engineers. Using examples from medicine, meteorology and climate science, experimental physics and engineering, this talk explains important properties of scientific models, as well as approaches to assess their relevance, correctness and limitations. For more than twelve years I have been interviewing scientists and engineers for my podcast omega tau. In many of the conversations, the pivotal importance of models for science and engineering becomes clear. Due to the pandemic and the climate crisis, the meaningfulness, correctness and reliability of models and their predictions is ever present in the media. And because most of us don't have a lot of experience with building and using models, all we can do is to "believe". This is unsatisfactory. I think that, in the same way as we must become media literate to cope with the flood of (fake) news, we must also acquire a certain degree of "model literacy": we should at least understand the basics how such models are developed, what they can do, and what their limitations are. With this talk my goal is to teach a degree of model literacy. I discuss validity ranges, analytical versus numerical models, degrees of precision, parametric abstraction, hierarchical integration of models, prediction versus explanation, validation and testing of models, parameter space exploration and sensitivity analysis, backcasting, black swans as well as agents and emergent behavior. The examples are taker from meteorology and climate science, from epidemiology, particle physics, fusion research and socio-technical systems, but also from engineering sciences, for example the control of airplanes or the or the construction of cranes.

It parks around. In this project, I investigated the parking behaviour for the case of Marburg (a city 1h from Frankfurt known for its university). The analyses comprise of a time series analysis, day-time usage of parking spots and the computation of periodicities in the parking signal with autocorrelations. Lastly, I used a Gaussian Process to predict the parking demand at locations that do not feature a parking deck - such as the university Mensa.

description: Amateurfunk ist tot - es lebe der Amateurfunk! Diesmal aber mit mehr Chaos, mehr Hacken und mehr Internet. Klassischer Amateurfunk dreht sich typischerweise um weltweiten Funkbetrieb und das Kontaktieren möglichst vieler Länder mit unterschiedlicher Funktechnik. Das ist sicher nett, aber in Zeiten von Internet und Highspeed-Netzen nicht mehr so spannend wie früher. Und auch wenn theoretisch das Selbstbauen und Modifizieren von Geräten im Fokus steht, werden die meisten Geräte heute fertig eingekauft und oft nicht tiefer hinterfragt. Unabhängig davon gibt es gerade im Chaos-Umfeld immer wieder Menschen, die sich auf ganz andere Weise mit Funk beschäftigen, z.B. mit dem rad1o-Badge, Decoding von Satellitensignalen, offener Implementierung von GSM oder einfach die Suche nach einer besseren WLAN-Antenne. "Der Zugang zu Computern [...] muss frei sein" gilt ja schließlich auch für das Physical Layer! Ich frage mich, ob wir den klassischen Amateurfunk nicht "forken" sollten und mehr Strukturen für das Hacken von und mit Funktechnik im Chaos-Umfeld aufbauen sollten. Dabei stellt sich die Frage, was wollen und was brauchen wir eigentlich? KnowHow-Plattformen für stärkeren Wissenstransfer im HF und DSP Bereich? Kostengünstige Messtechnik? Ein Event, an dem wir mal direkt vor Ort mit HF und Funk frickeln können, mit geeigneter Technik? Dieser Talk thematisiert zunächst die Probleme, die sich im typischen Amateurfunk immer wieder ergeben, und begibt sich dann auf die Suche nach den Zutaten für mehr "Chaos" und wieder mehr Spaß mit Funktechnik.

Type theory and meaning in linguistics

uk: Комп'ютерні науки

description: Type theory has a large influence on computer science for example in functional programming languages such as Haskell. However, it can also be relevant in linguistics and help to answer the question what "meaning" for natural languages is. This talk presents approaches to explain meaning of natural languages statements using tools from logic and computer science Type systems are popular in computer science, for example among functional programming languages such as Haskell and various ML dialects. The theory behind these type systems, called type theory, is an active field of research both in computer science and logic. Another field where type theory can be relevant is natural language semantics, the study of meaning of natural language statements. It is a difficult task to specify in a rigorous manner what "meaning" should be in the context of natural languages. This talk will discuss the concept of meaning for natural languages, present some of the formal approaches to meaning established in the last 50 years and show how type theory and other tools from computer science can help us to express meaning for natural languages.

description: This talk provides a practical guide for how to solve interpersonal conflict in communities with a loose structure such as do-ocracy or anarchy. We explain how Hackerspace.Gent uses the "private talk" pattern to solve conflict between members. We share our experience in the hope that this can help you fix issues in your community so it can go back to doing awesome stuff! Interpersonal conflict is a common but dangerous issue in communities. It's not always easy to deal with it, especially when a community is loosely structured without formal authority. Communities built on do-ocracy or anarchy can be awesome breeding grounds for creative work and powerful ideas, but they are very vulnerable to drama. Seven years ago, we experienced this first-hand at Hackerspace.Gent when our community fell apart because of conflict. At our lowest point, we decided to "hack the hackerspace" to find systems and techniques to build a better community. Over the years, one of the most useful tools for keeping our community healthy turned out to be the "private talk pattern", a method for solving conflict between two people. This tool doesn't require clear authority or policing, which makes it perfect for less-structured organizations such as do-ocracies and cooperatives. With this talk, we share our experience with the hope of giving you more tools to make your community great.

description: In a Pandemic it becomes clearer than ever - proprietary IP and copyright ownership models fail society’s needs on every level. The pandemic has brought topics like sustainability and resilience into the limelight. Local production suddenly seems on everyone's lips as it could help to solve shortages that post a threat to our society. However, in the landscape of proprietary products it is simply not possible to provide the software, hardware schematics and know-how to everywhere in the world at the speed required. Traditional proprietary IP controlled distribution models, business development practices and hiring processes do not work in a pandemic and they do not work in a world threatened by climate change. A famous example how proprietary supply chains failed was the shortage of ventilators in many parts of the world at the beginning of the pandemic when borders are closed.Sharing knowledge openly and developing solutions collaboratively in the open source way provides a proven alternative which could be literally live-saving in a pandemic. In this session I will discuss what opportunities open source software and hardware provide to society in these times, what long term benefits global knowledge, design and technology sharing will have and how local production can even help to save the climate.

description: Estimates suggest that well over 100 bn € is spent on autonomous vehicle research, or what we might call the “Technology Mobility Complex”. Over recent years dozens of high-profile autonomous vehicle projects claim they are tantalisingly close to launch, only for those projected dates to be quietly pushed back. This talk will critically examine the inflated claims of the self-driving car industry and argue that the hyped economic and social benefits are based on unproven and dubious assumptions; furthermore, that the intractable paradoxes self driving cars present between ethical goals and technological goals; centralised and decentralised systems; as well as data availability and privacy make the challenges of realising fully autonomous mobility all but unsurmountable for decades to come. Drawing on leading research in the field, the speakers will argue that: The ethical and technical challenges of autonomous mobility are deeply inter-meshed. The very concept of an “autonomous vehicle” deciding ethical situations, as defined by the tech and car industries, is flawed and in itself a barrier to progress. The challenges include intractable ethical dilemmas (I.e. the trolley problem), which are currently unsolved, bearing a significant risk that the tech/car industries will use their economic and political influence to override them. Also challenging is, that autonomous vehicles will necessarily be prodigious data collection and surveillance devices and could violate privacy on an unprecedented scale. Even now with only “level 3 autonomy”, every Tesla on the road has 8 HD cameras and 12 ultrasonic 360 sensors constantly collecting data – estimated at around 25 GB an hour – that is shared with Tesla data centres. Another challenge is the distraction from more urgent mobility challenges, that threatens to lock us into a mode of transport that accelerates further towards the tipping point of global ecological collapse. Self-driving car technologies will necessarily depend on connected systems; the more assets are feeding the data collection, the better the algorithm and system´s abilities will become, so the “technology mobility complex” might simply represent a new arena in which the tech companies can invest super normal profits to extend their monopoly platform power. Alistair Alexander is a researcher, trainer and campaigner on the links between technology, society, ecology and art. At Tactical Tech he led the award-winning Glass Room project, exploring data and privacy with immersive art in pop-up spaces, reaching over 120,000 people worldwide. While studying Philosophy & English at Humboldt University, Auris-E. Lipinski became a scientific assistant at a Berlin based IT Company for optimisation, monitoring, planning and data analysis, where she had the opportunity to get a deeper understanding of telematic systems, sensor & map data, thusly connected computer systems, and the fields these technologies can be deployed in. She founded the PhenCoCo project for scientific discussions in the aftermath of seminars like "Konstruktion und Phänomenologie der Wahrnehmung", Phänomenologie und Kognition" (M. Thiering) and "Computation und Geist" (J. Bach). She has been involved in different research and development projects, guiding her academic interests towards way finding and cognitive preconditions for navigation, both computational and phenomenological. This includes working on spatial concepts found in philosophy, psychology and robotics, subsuming Gestalt theory, embodiment theories, language/ concept importance, association and intuition. It also includes a continuing interest in programming methods and environments, as well as machine learning algorithms.

The value proposition of an ungoverned, uncensorable digital means of value transfer is clear for all to see…but can humanity and Earth afford the thermodynamic price tag? To maintain the integrity of the transaction record, the Bitcoin network creates a hard boundary to the outside through exacting validation requirements. However it does not possess any feedback mechanism or capacity to respond to the consequences of the thermoeconomic challenges it issues. This insensitivity of ‘mined’ cryptocurrencies to the energy sources used to secure them has led to criticism as to their inability to mitigate their ecological externalities.

description: This talk presents an extensive security analysis of trusted-execution environment shielding runtimes, covering over two years of continuing research and leading to 7 CVE designations in industry-grade Intel SGX enclave SDKs. For the first time, we develop a systematic way of reasoning about enclave shielding responsibilities categorized across 11 distinct classes across the ABI and API tiers. Our analysis revealed over 40 new interface sanitization vulnerabilities, and we developed innovative techniques to aid practically exploitation through among others CPU register poisoning, timer-based single-stepping, rogue CPU exception handlers, and side-channel-based cryptanalysis. We finally analyze tendencies across the landscape and find that developers continue to make the same mistakes, calling for improved vulnerability detection and mitigation techniques. This talk overviews the security and state of practice of today's Trusted Execution Environment (TEE) shielding runtimes from both industry and research. Our systematic analysis uncovered over 40 re-occurring enclave interface sanitization vulnerabilities in 8 major open-source shielding frameworks for Intel SGX, RISC-V, and Sancus TEEs. The resulting vulnerability landscape enables attackers to poison victim programs through both low-level CPU state, including previously overlooked attack vectors through the x86 status flags and floating-point co-processor, as well as through higher-level programming constructs such as untrusted pointer arguments passed into the shared address space. We develop new and improved technique to practically exploit these vulnerabilities in several attack scenarios that leak full cryptographic keys from the enclave or enable arbitrary remote code reuse. Following extended responsible disclosure embargoes, our findings were assigned 7 designated CVE records and led to numerous security patches in the vulnerable open-source projects, including the Intel SGX-SDK, Microsoft's Open Enclave, Google's Asylo, and the Rust compiler. Our findings highlight that emerging TEE technologies, such as Intel SGX, are _not_ a silver-bullet solution and continue to be misunderstood in both industry and academia. While promising, we explain that TEEs require extra scrutiny from the enclave developer and we set out to identify common pitfalls and constructive recommendations for best practices for enclave interface sanitization. Throughout the talk, we overview shielding responsibilities and argue that proper enclave hygiene will be instrumental to the success of the emerging Intel SGX ecosystem. Additionally, we point to several subtle properties of the Intel x86 complex instruction set considerably increase the attack surface for enclave attackers and require the end developer to be aware of their respective shielding runtime or apply additional sanitizations at the application level itself.
