eBPF is transforming Linux system capabilities, enabling the extension of the kernel with custom process schedulers, firewalls, and more. Thanks to Java's recent native integration and a bit of compiler magic, we can now create these extensions directly in Java and use it to create Linux schedulers that create sound and schedulers that emit sound. After this talk you'll know how to create your own Linux scheduler, made your computer run faster by shouting at and played with the first ever Idle game that controls a scheduler.

Can we trust the Zero in Zero trust? (WHY2025) 38:02

1 day پیش38:02

38:02

Zero Trust (ZT) has evolved from pure network access to hype. ZT Everywhere has become a buzzword. If you ask about it during product presentations, the sales person sometimes runs out of the meeting. If we look beneath the surface, we find a lot of code that we trust in zero trust environments without realising it. Istio containers in service meshes, key management systems in SSH/Ansible environments and a whole lot of legacy code in confidential computing require trust in strange containers, ex-employees and attestation processes and a CI/CD pipeline for microcode in the cloud. What questions should we ask ZT? As the management of keys is crucial for TLS (encryption on transport), disk encryption (encryption on rest) and the new kid on the block confidential computing (encryption of data in use) we look under the carpet of implementations and raise a lot of questions to ask if implementing the concept. This immediately affects any digital souvereignty. Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://program.why2025.org/why2025/talk/3EHJGJ/…

About Time (WHY2025) 43:38

1 day پیش43:38

43:38

A shared understanding of what time it is and the rate at which time progresses is essential in many areas of technology from industrial control to broadcast. There are two main ways of synchronizing time between multiple computers, Network Time Protocol (NTP) and Precision Time Protocol (PTP). NTP is sufficient for certificate validation, but when timing is crucial we need PTP. In this talk we will take a deep dive into PTP: what it is, how it works, and various ways to abuse it. In my previous talks about Audio over IP and AV technologies the Precision Time Protocol has come up repeatedly as something that deserves its own talk. PTP has a wider use case which makes it interesting as a target for shenanigans. The talk aims to consolidate several years of experience and research into a concise understanding of this fundamental technology. No prior knowledge about PTP or network time will be assumed. Some familiarity with networking basics will be helpful, but not essential. Warning may contain hacker humor.

1 day پیش43:58

43:58

After some internal evaluation and a journalists inquiry on the possibility of chinese state actors having access to camera footage, Muncipality the Hague decided to do a security test focused on an APT threat on their traffic camera infrastructure. During the session we will show how the team approached this project, how some of the cinematic scenarios of causing traffic jams and using the camera's for espionage were possible in real life and what lessons were learned from the project. The session will start with providing a bit of context on why the project was started, what was already going on at that time and why the muncipality of the Hague had further questions for which they needed a hacking team. We then discuss how we approached the project in a complex environment, where APT threats are involved and how that changes how you assess certain systems and features. The core of the presentation focuses on disclosing the actual vulnerabilities found within the systems, how we went through the full cyber kill chain within the environment and what that actually means in the physical realm if this had been exploited with malicious intent. Finally we end the presentation with some details on how the discovered issues were addressed and what general lessons can be learned from this project that could also be applicable for other similar environments.

How do you scale up victim notifications from a couple of hundreds, to thousands, to millions to billions of stolen credentials? Credential theft is on the rise. Cybercriminals are gettings smarter and more efficient. Why hack in, if you can log in? At the DIVD we see this trend in the cases where we assist with notifying victims of credential theft. Where our first such cases started with a mere threehundred-something credentials we are now sometimes faced with credential dumps that contains millions of even billions of credentials. How can we scale this up, what problems did we face, how did we solve them, and what haven;t we solved yet?

Experiences from a hacker working at the Election Council of The Netherlands. After critically following the elections for 8 years from the outside, a hacker was employed as one of the functional administrators of the software supporting the elections. Sharing experiences of the use of election software during 7 elections (2020-2023), from local, national to European in The Netherlands. A governmental software project with strict deadlines, and high security expectations. The software project for elections in The Netherlands is build an IT organization owned by German local governments. More than 10.000 Java files, what can possible go wrong? During this time multiple emergency patches were needed and incidents occur. Although at first explicitly not hired as a coder, within 3 months a Java code contribution was made that was unexpectedly more crucial than anticipated. This talk will show some incidents with the election software in The Netherlands: how the software failed, and when/how it was discovered. Go over how seeing the elections from the outside, and give some history of voting computers and software. Ending with some reflecting on the future.

Time Lord's adventures: abusing time on Linux systems (WHY2025) 22:49

۲ روز پیش22:49

22:49

What happens when an attacker controls time on a Linux system? This talk looks at how system clocks work, and what breaks when they’re manipulated. From bypassing delays to triggering subtle logic errors, we’ll explore how unstable time can subvert assumptions, break security controls, and cause software to behave in unexpected or unsafe ways. This talk explores the consequences of full control over time on a Linux system. We’ll start with a brief overview of how system clocks work, highlighting common assumptions made by applications and security mechanisms. The focus will be on local manipulation of the system clock — jumping forward, rewinding, or freezing time — and the unexpected ways software can break when time becomes unreliable. Through practical examples, we’ll see how time-based defences and logic can be bypassed, exposing vulnerabilities that often go unnoticed. Not every issue leads to a full exploit, but many reveal fragile trust assumptions rarely tested in real environments. This talk is for hackers, tinkerers, and developers who’ve ever relied on `sleep(1)` as a defence mechanism. You might rethink your assumptions about time-based security after attending.

Are you interested in maps? Are you searching for a FLOSS mapping navigation? Do you need geodata? Do you need a map on your site? Do you want to help creating maps from your local environment or from vulnerable places? Then, you have come to the right talk! This talks gives a broad overview of OpenStreetMap, the community and how to get started with it. OpenStreetMap is an open database of geodata and has become the biggest geodataset of the world. It is often called 'the wikipedia of maps' and is getting used in more and more applications - from grassroot movements to big corporations. A tremendous lot is possible, but it can be confusing to get started and to dive into the ecosystem. In this talk, I'll give a high-level overview of OpenStreetMap and answer the most important questions: - What is OpenStreetMap (and what is it not?) - What applications exist? - What tools exist? - How can one contribute? - How can one export data? - How can one get in touch with the local mapping community? No previous experience with mapping or GIS needed! This is a talk, so you don't have to bring anything. However, if you need some help with your first OSM-edits, I'll stick around after the talk to get you started. In that case, it might be useful to bring your laptop (or smartphone) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://program.why2025.org/why2025/talk/LLRPVY/…

LLM outputs have quickly spread like radionuclides, threatening everything from the scientific record to the existence of the Internet as we know it. In this talk I'll discuss _practical small web approaches_ that we can use to build a new Internet that doesn't suck quite so badly. There will also be memes ;-) Have you noticed how the **good stuff** on the Internet is increasingly hidden behind bot checks, subscriptions and paywalls? And that it's getting harder and harder to find things online due to LLM pollution? Welcome to the club! You are in the right place. In this talk I'll highlight some of the most egregious examples, consider how we can best preserve _low background information_ for future generations, and how we can use small web techniques like **self-hosted blogs and static site generators** to bootstrap a new infosphere that doesn't rely on a handful of _hyperscale operators_. I'm particularly interested in how we can _federate and syndicate search_, learning from protocols and standards like RSS and ActivityPub. As part of the talk I'll give you some practical tools and approaches to try.

Did you know that if you change a single bit from 1 to 0 (or vice versa) in the first 'g' of the domain name google.com (which is 01100111 in binary) you will end up with variety of valid "bitflip" domains like coogle.com, oogle.com, & woogle.com So what happens if you generate and register a bunch of cheap bitfliped versions of popular cloud / Saas provider domains, point them to your VPS, log all incoming requests & then forget about the whole thing for two years? Well you will in fact receive a stiff bill, generate huge log files and eventually run out of disk space. But on the upside, you will also have collected a treasure trove of legit credentials & interesting stuff like valid OAuth refresh tokens, JWT tokens, bearers, cookies, emails, meeting invites with passwords & truckloads of internet scanner noise. In this session we will revisit bitflip research from the last decade and weponize it. Showcase 'Certainly' a pioneering offensive / defensive tool that employs Wildcard DNS matching & on-the-fly generated SSL certificates and custom payloads for incoming requests across various protocols.

A journey into reverse engineering arcade PCBs for video game preservation via FPGA emulation (WHY2025) 48:10

۲ روز پیش48:10

48:10

Sometimes ago, I embarked on a journey into the world of electronics and FPGA technology with no prior knowledge. What began as passion for retro gaming evolved into a quest for preservation via reverse engineering and FPGA-based emulation. This presentation will share my journey, highlighting the challenges of learning Verilog, the tools, the resources, and the lessons I learned along the way. By sharing my experiences I hope to inspire others to contribute to preservation of video games. **Abstract:** In an era where classic arcade games risk becoming obsolete, preserving them is crucial. This presentation chronicles a journey from curiosity to creation, demonstrating how FPGAs can be used to create accurate emulator. **Introduction to FPGAs:** FPGAs are versatile integrated circuits that offer unparalleled flexibility for hardware design. Unlike fixed CPUs or GPUs, FPGAs allow for reconfiguration, making them ideal for creating custom solutions like game emulators. This section will explore the advantages of FPGA-based emulation over traditional software emulators, and the existing plateform like the MiSTeR FPGA. **Verilog Programming:** Verilog is a hardware description language used for defining digital circuits in FPGAs. This part introduces Verilog's role in designing these circuits, and how it differ to traditional programming languages. **Reverse Engineering PCBs:** This segment breaks down the process of reverse engineering an arcade PCB. From identifying components and they're connections, to reverse custom IC and schematics creation. **Creating an arcade games core** A case study on the creation of an arcade game FPGA core. Challenges faced during development, and specifities of arcade games emulation. **Conclusion :** The presentation concludes by encouraging attendees to embark on their own journey, offering practical advice and resources tofacilitate their exploration into FPGA-based gaming preservation. The goal is to inspire and equip newcomers with the knowledge and tools to preserve classic arcade games through FPGA emulation.

Four Freedoms of Social Media Protocols (WHY2025) 27:03

۲ روز پیش27:03

Our digital communities are controlled by corporate platforms that surveil, manipulate, and arbitrarily deplatform us. We need a Bill of Digital Rights—ensuring privacy, ownership, algorithmic control, and self-governance. This talk lays out the Four Freedoms for Social Media and how open protocols like ATProtocol, ActivityPub, and Nostr make them possible. The future of social media must serve communities, not corporations—and we must demand it. The Four Freedoms of Social Media: A Bill of Rights for Digital Communities Just as free software has the Four Freedoms, our digital communities need Four Freedoms for Social Media—fundamental rights that ensure people, not corporations, control their online spaces. Social media today is defined by surveillance, manipulation, and arbitrary control—but it doesn’t have to be. This talk lays out what we must demand from social protocols: 1. The Freedom to Connect – No one should be prevented from communicating or organizing due to corporate interests or government pressure. 2. The Freedom to Move – Users and communities must be able to leave one platform and take their relationships, content, and identity elsewhere. 3. The Freedom to Understand & Control Algorithms – People should know how their feeds are shaped and have the power to change them. 4. The Freedom to Self-Govern – Communities should set their own rules, rather than being subject to arbitrary moderation and deplatforming. Technologies like AT Protocol (BlueSky), ActivityPub (the Fediverse), and Nostr offer glimpses of this future, but they must be built around these freedoms—not just as features, but as non-negotiable principles. This talk isn’t just about what’s possible—it’s about what we must demand from the next generation of social protocols. The future of digital communities should belong to us—not corporations.

MEMS (Micro-Electro-Mechanical Systems) sensors are miniature, highly precise components that detect motion, position, and environmental conditions. They are widely used in smartphones, cars, wearables, and smart home devices and are manufactured in specialized cleanrooms using advanced semiconductor processes. This talk starts with a short introduction covering: What are MEMS? How are they made? What can the Bosch BMI270 (6-axis IMU) and BME690 (gas, humidity, temperature, and pressure sensor) do? After this overview, we’ll switch to a practical session: you’ll learn how to get started with MicroPython to access real-time sensor data on the WHY2025 Badge. By the end, you’ll be ready to experiment with your own ideas and prototypes based on the badge’s powerful sensing capabilities.

Automate yourself out of supply chain hell (WHY2025) 49:42

۲ روز پیش49:42

49:42

Modern software development and operations heavily relies on third-party applications, libraries, containers etc. This presentation will showcase how dev, ops, but also security management can be transparent about dependency versioning and known vulnerabilities, while also staying on track with updates. It will show demos of Open Source Standards like SBOM and Frameworks like Dependency-Check, Dependency-Track and Renovate that can help automate the sadness of today's supply chain issues.

WHY Lightupyourbanjo (WHY2025) 42:07

۲ روز پیش42:07

42:07

The Light and Music entertainment platform Lightupyourbanjo began in 2010 when “Cash-a-billy with a Bluegrass bite” band Ed and the Fretmen wanted to have better lights on their banjo. They developed banjo lights with addressable LEDs for in and outside mounting showing interactive animations, written in C++ supporting the songs, and wrote songs to support the lights. In 2025 the Lightupyourbanjo bands will be fighting the darkness with the new O4 model build into their 3 banjos. In the WHY Lightupyourbanjo talk, we will look at the world of banjo lights, present the new O4 model and features, apply the 5xWHY analysis on this all to explore the greater meaning, and finally we hope to bring some Light and Music to WHY 2025. https://www.youtube.com/watch?v=_j19nTYNWv4 Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://program.why2025.org/why2025/talk/9NQTEL/…

Using deployment diagrams to explain architecture and security to everybody (WHY2025) 39:34

۳ روز پیش39:34

39:34

This talk will enable you to lead architecture conversations and discuss their security options through an informal diagramming technique. I will use examples such as key/encryption architectures, DevOps, and even your home music system. Presentation at https://digitalinfrastructures.nl/why2025/ You have seen many diagrams of computer and information systems in your career. They have been around since the early days of computing. They can be useful, but there are a few typical problems with them: • They are drawn with obscure symbols that are only understood by architects • They are drawn in an inconsistent way • They are not used to their fullest potential. In my practice I have run into these problems often, and I have found ways to turn a certain type of diagram, a simplified version of deployment diagrams, into the cornerstone of explanation of what goes on in cloud and cybersecurity. In the talk I will lead you through the basic principles, and a few examples. This will enable you to lead architecture conversations and discuss their security options. I will use examples such as key/encryption architectures, DevOps, and even your home music system.

Offworld Voyage: Can Training for Mars Exploration Also Address Human Adaptation to Climate Bio-devastation on Earth? (WHY2025) 46:53

۳ روز پیش46:53

46:53

This talk will present the design philosophy behind Offworld Voyage, a decentralized science initiative that develops ecologically sustainable training habitats for use in simulated Mars surface exploration missions - while also solving for adaptation to extreme climate change on Earth. The Offworld Voyage M.A.R.S. Tesseract Space Analog Simulation Habitats were designed with a zero waste ethos for minimal environmental impact by inventor Scott Beibin and visual wizard Michael Flood. The modular and portable structures of the habitats include: a bio-dome for cultivating organic vegan plant-based and fungi-based nutrition sources, autonomous power production, advanced waste reclamation, a science laboratory for experimentation and research, a space medicine bay, a fabrication lab for prototyping and repair, facilities for fitness and creativity as well as a kitchen and living quarters. Mission immersions incorporate a vision of the future when space has become accessible to all through the use of emerging ecologically sustainable appropriate technologies enabled by new types of egalitarian economic structures and coordination methods. Crew activities include EVA explorations in pressurized space suits outfitted with bio-sensors, 3D printed construction using regolith, utilization of open source communications tools, cooperative governance exercises and the practice of mutual aid and consensus decision making in mission planning, problem-solving and self-sufficiency challenges in the face of extreme resource scarcity, simulated time-delayed communications and experiments to analyze the effects of isolation on astronauts during offworld missions. The inaugural mission for the M.A.R.S. Tesseract habitats will occur in a remote desert location in the near future. It will include the founders of the project, Scott Beibin and Elizabeth Jane Cole, who are both alumni of the Mars Desert Research Station (Mission 286) and core committee members of the Journal for Space Analog Research. Future plans for the project include the development of pressurized facilities and closed loop systems, as well as development of public goods including hardware and software for Space Analog Research and S.T.E.A.M based educational programs.

You've maybee seen the raking robot that got a CEH (Certified Estetisch Harker) certificate, the Telex linked to Twitter/Telegram or the ASCII foto booth. They are all made by me. If this talk gets accepted I will do a deep dive on these three contraptions and what I learned building them. Beside Schuberg Philis, DIVD, attending the farm and keeping my bees I als build machines. It is an interesting process and I want to share it with you. Machiens I will be talking about: * The (worlds?) 1st 3d color printer from TNO * The raking robot * AI/Twitter/Telegram/Slack connected Telex * ASCII photo booth Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://program.why2025.org/why2025/talk/FYPY7C/…

Caveat Emptor: Ratings and Reviews Can't Be Trusted (WHY2025) 50:02

۳ روز پیش50:02

50:02

It's hard for a platform to have meaningful, useful ratings/reviews without both substantially Knowing Your Customer, engineering to detect manipulated reviews, and responding in a nuanced way -- to increase a fraudster's costs, and not just train them to hide better. Lots of examples of diverse platforms not doing a very good job of this. (I'll also talk about how this knowledge sometimes leads platforms try to manipulate their own customers to maximize their sales). Ratings and reviews, although almost universally relied on by consumers, are, like much other online info, often manipulated to increase sales, pump up merchant reputation but are sometimes used malicious to slam a competitor). Even sites that only allow reviews from purchasers can be manipulated, particularly on platforms when low cost products are sold. Ebay harbors fraudulent sellers by combining buyer and seller reputation, and not weighting by sale price. (So a 5 star rating for a trivial purchase accrues equal reputation as a large value sale.) Many manipulations should be easily detectable by looking for some clear behavioral signatures, and then not training the adversaries by using adversary engineering rather than simply deactivating accounts. (I'll show you how to spot a lot of the red flags.) Examples ranging from pumped up restaurant listings (up to #1 in London), Amazon and Ebay's problems, a puppy sales site that had a rating system so bad by design that they were sued by an animal rights org for facilitating fraud by puppy mills. (There are a lot of sick puppies out there...) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://program.why2025.org/why2025/talk/CJQD7U/…
