Eye on the sky: building investigative journalism...

Chaos Computer Club - recent events feed ·

2025/08/09

What aircraft have been in Moscow and New York within 24 hours of each other? How many helicopters normally patrol this border? At Bellingcat, a Dutch investigative non-profit, we publish open-source journalism using open-source software tools. In this presentation, I'll talk about a new tool I've been building for querying airplane data, and the broader journalistic context of this data, which has become increasingly important for tracking oligarchs, deportations and conflict.

The "O" in OT...or is it the "Ohhhh..." in OT? (WHY2025)

Chaos Computer Club - recent events feed ·

2025/08/09

"De ‘O’ in OT – Operationeel, Onmisbaar, Onbeschermd?" Operational Technology (OT) is de ruggengraat van industrie en kritieke infrastructuur, maar blijft vaak onbeschermd. Traditionele IT-security werkt niet in OT, waar continuïteit essentieel is en stilstand geen optie. Hoe beschermen we OT zonder operaties te verstoren? In deze sessie bespreken we dreigingen, regelgeving (NIS2, CRA) en strategieën om OT echt veilig te maken. OT is onmisbaar – laten we zorgen dat het beschermd blijft. Operational

What's that CubeSat Satellite stuff anyhow? (WHY2025)

Chaos Computer Club - recent events feed ·

2025/08/09

CubeSats are small satellites comprised of 10x10x10cm "units" and range in size from very small 1U or smaller PocketQubes to 24U beasts. What can be achieved with such a satellite platform and why? I will go in to a brief history with examples from customers and amateur radio CubeSats. During my 20 years working with CubeSats, starting with designing parts of the Delfi-C3 student satellite in 2005, I have seen many missions and I have been involved in the design of quite a few CubeSats. Often,

Horus Scenario 2.0 (WHY2025)

Chaos Computer Club - recent events feed ·

2025/08/09

8 years ago at SHA2017, the horusscenario was presented. A Theoretical attack through PV-installations to take down the european energy grid. Since that day, a lot of things have changed, both for the better and for the worse. During the session, we will look back into the horusscenario with today's knowledge and revisit if the attack is still feasible. (Spoiler: I was right... and it has mainly gotten worse since then...) During the session we will look back on what was said in 2017 and what we

2025/08/09

In a context of technological integration, OT is getting more and more a green field for attackers and illegal activities. This phenomena is the natural result of the absence of mutual understanding and collaboration between IT and OT sectors that looking one each other as a totally unrelated entities. In this talk we'll explore some OT technologies trying to understand and highlight some of the most relevant aspects of the OT security and we'll have a look to a couple of real incidents in

DNA & Molecular Biology: A 2025 digital view (WHY2025)

Chaos Computer Club - recent events feed ·

2025/08/09

In 2017 I presented on DNA: The code of life. Since then there have been many new developments, and I've learned how to explain the matter better. I am submitting two talks this year, and this short one is 1) fun on its own and 2) helps you appreciate the other talk ('reverse engineering the whole source code of a bacterium') more DNA is the code of life. Surprisingly, it is easier to understand DNA as "biologically flavored digital data" than the other way around, "a really long molecule with

2025/08/09

Have you ever thought that Mathematics is a boring science about multiplying matrices, calculating integrals and approximating functions? Well, you've been wrong. Mathematics is much bigger than that and in this talk we are going to look at one of the foundational object in Topology - a manifold. And, most importantly, we won't need any formulas or calculations to introduce it. (No prior knowledge of any level is required) As a PhD in Geometry and Topology, working in Software Engineering, I

What is up with the beings with the visors going 'beep boop, this one is not a person'? Unit Δ-44203 explains how it built an electronic face, why it did so and what consequences it experienced in a world where everyone is supposed to show an identifiable face all the time. Warning: this talk may be cognitohazardous and end up causing shifts in self-identity. — Can I see your face? — You are looking at it.

Old technology is amazing! Have a look at an old electromechanical Pinball Machine, and try to understand how this works, without any (digital) electronics. Find out these machines have much in common with modern computers. Step by step it becomes clear how an old (1973) Pinball machine is "programmed". A 1973 electromechanical Pinball Machine is an amazing machine. But how does this work without any (digital) electronics? By comparing this to a standard computer, the (mechanical) components are

From WAN to NAS: A Pwn2Own Journey Through the SOHO...

Chaos Computer Club - recent events feed ·

2025/08/09

The SOHO Smashup is a famous category in the IoT focused edition of Pwn2Own. Contestants are challenged to exploit a router from the WAN side and then use that device to exploit a second device on the internal LAN. Last year, we took them up on this challenge and successfully demonstrated a 0day exploit chain against a QNAP router and pivoting to a TrueNAS system. In this presentation, we'll describe how we performed our research and the vulnerabilities we found. The Dutch NCSC issued a warning

2025/08/09

Let's talk to people about negotiating consent before engaging in personal and physical interactions. Your browser does it with every web server, so why shouldn't you do the same with people? This sounds harder than it actually is. Using the HTTP protocol as a guide this I will talk you through how you could negotiate consent to engage with someone on a variety of levels: From 'GET Hug' all the way to 200 OK, but also how to deal with a 404 Consent not found response. Consent is hot. Consent is

This talk will take you into a journey leading to the retrofit of a robotic tape library to enable it to accomodate hard drives in addition to the original media, from the reasons we did it to all the obstacles that needed to be overcome and how we did all that, pushing a little further the physical limits that make data storage increasingly problematic in a world where over 200TB is generated every second and must sometimes be retained for years (and possibly more). Every year, humanity generates
