Only three years ago you wouldn't have had a chance to get this so-called reality past any decent editor. Now, plotting a book or movie has become increasingly hard and the next years in publishing will be interesting, since our standards in what is scary or believable or how dumb can one be to do XY as a book character, to get into whatever problems, have tremendously changed. I'm an author, writ...

We will discuss what happened on the front, how it helped to turn the war in Ukrai...

Mechanical locks are everywhere and come in all shapes and flavors. But choosing the right lock can be rather difficult. For example, what is better? A lock that is hard to pick, or a lock with hard to duplicate keys. This talk will not give you the answers, but it will help you understand the trade-offs. Furthermore, we will have fun threat modeling our locks. Is lockpicking a threat you should b...

As of today, most discussions on cyber security focus on privacy and the implications of incidents involving data. However, those of us in cyber physical security often see things differently as we study actors attempting to use computers to impact the physical world (e.g. critical infrastructure and industrial controls). Geopolitical conflicts and accessible offensive security tools make defendin...

There’s no quick fix for the misinformation, disinformation, and lies were seeing in the world these days, and its natural for hackers want to work on the problems with the skills at hand. I’m going to talk about why, for hackers, that’s not necessarily a good move to do solo. I’ll go over mistakes I’ve seen way too many technologists and academics make when approaching the subject, where misinfor...

drand is an opensource project allowing anybody to run a “randomness beacon”. Its goal? Providing a trustable, verifiable source of public randomness that would enable full transparency in online lotteries, leader election or blockchain smart contracts. This talk is about what distributed randomness is, what it means for developers, and users, and why you’d want to use it. I will also present to y...

If the perfect Blue Team exists, does that mean the Red Team doesn’t stand a chance against it or is there still a way to sneak their phish in the mailbox of their target? Well in this talk we investigate how a Red Team could sneak past even the best Blue Team imaginable. We analyse how a perfect Blue Team would detect malicious domains targeting their organization, how they would correlate these...

The talk is on Introduction to opens source investigations. Aiganysh will explain what "open source" is, what kind of research you can do with it, and the challenges it entails from Bellingcat's experience. The presentation will be full of case studies and exercises such as geolocating ISIS supporters from Twitter and identifying neo-nazi criminals in the US. Bellingcat has conducted open source i...

We will take a cursory look at the protocols that underpin audio over IP from studios to stages and on to broadcast. Focusing on AES67 the you will gain a basic understanding of what it is, how it works and how it is inherently vulnerable to attack. At a high level this talk should be accessible and entertaining to all, although to grasp the more nuanced details a rudimentary knowledge of IP netwo...

Hardware attacks on security relevant components, such as fault injection, have been known for decades and have been shown to be successful on a wide range of devices ranging from general purpose microcontrollers to dedicated security engines. In this work we give an overview of different methods used for fault injection and the effectiveness of these methods. We discuss electromagnetic fault inje...

The Gigatron is a microcomputer without a microprocessor. It was made into a DIY electronics kit and sold over 1000 pieces from 2018 to 2020. It is now open source. In this talk, I will not go into the working of the kit, but explain what you need to think about when creating a kit and keeping it manageable. Think of what to design, sourcing components, testing, preventing too many support calls a...

Governments should be radically more transparent. While calls for more open data and initiatives like the Open Government Partnership have existed for more than a decade, there is still much to be desired. Where do we stand? And, fun to imagine, where could and should we go? It is hard to have a perfect overview of the status of open government across the world. We at [Open State Foundation](https...

Digital maps are ubiquitous tools in our everyday life. In the early 90s, the idea of browsing the world digitally and visiting any place was groundbreaking. The first solution to this problem is known as "TerraVision", which was breathtaking at that time. Today, the idea of exploring your surroundings using digital maps has become pretty normal. But how do these maps work? In this talk, I want to...

IRMA is a system in which you are in control of sharing specific personal properties (aka attributes) such as your age, address and gender which are stored in the IRMA app on your phone. Technically, IRMA is a set of free and open source software projects implementing the Idemix attribute-based credential scheme. Although the Idemix credential system has been around for a while it is still relevan...

Predictive policing is hip and happening. In the last few years we have seen a number of experiments with predictive policing in The Netherlands. How does that technology work? What were the outcomes of the experiments? And what is the legal status of a suspicion generated by a computer? "Predictive policing" is the name of a family of technology that use historical crime data to make predictions...

Microbes are everywhere. They are part of nature, both around us and inside of us. When you provide their desired niche, you can make them do something for you, in a mutually beneficial arrangement. This talk will take you into their realm, and show a few practical examples and hacking opportunities. Our climate is on fire, but we are still reaching for an Ultimate Solution. We don't move until we...

This talk will investigate how the concept of private property has fundamentally altered our behavior towards the environment. We will investigate how an alternative ontology of electronic waste is needed and argue why dumpster diving, hacking and reverse engineering abandoned electronics is more relevant than ever to tackle this problem. Within the discourse that surrounds the global rise in elec...

Enterprise web applications have been deployed rapidly to the internet over the last ten years. Often, these applications remain secure, purely due to how difficult it is getting a copy of the source code. Unsurprisingly, some of the most popular enterprise web applications contain critical pre-authentication vulnerabilities. This presentation discusses how to get your hands on enterprise web appl...

I present background, rationale and future plans of Scientist Rebellion, a growing international group of currently over a thousand scientists venturing into civil disobedience since writing more papers about the climate emergency does not yield the needed political sense of urgency and actions. I'll present Scientist Rebellion, an international group of scientists taking the scientific view of th...

Building Web-Applications is hard. Making them scale is even harder. And nobody said anything about robust yet. Looking back over the past 25 years of Web-Development, not much has changed, except for tooling and languages. The approaches we use, also have not changed much. We still write lots of JavaScript, put special glue in between layers of languages, it's bleak. Building Web-Applications is...
