Mythos and Cybersecurity

Since Anthropic announced that it’ll not publicly release its newest Claude Mythos model because of concerns around its capabilities in exploiting software vulnerabilities, I have been searching for a good analysis of this non-release. I wondered whether this was truly responsible disclosure or nothing but a marketing stunt. Bruce Schneier’s take on it finally answered (…)

They Buried a Trillion Dollars Underground. Then the Internet Was Born.

I took part in this ‘fibre rush’, and I always emphasise that digitalisation fundamentally requires substantial physical infrastructure. Learning from history can help us to identify patterns that we should take into account during today’s AI boom. However, there are also crucial differences: data centres incur significantly higher maintenance costs, and GPUs depreciate much faster (…)

Stanford just proved your AI chatbot is flattering you into bad decisions

We’re used to the terms “echo chambers” and “filter bubbles” when discussing the dangers of social networks, search engines, and personalized ads. Now, with AI chatbots, a new term joins the ranks: “sycophancy”, or telling people what they want to hear. Could sycophantic chatbots be more harmful than social media echo chambers? My gut says (…)

Japan’s Team Mirai Uses Tech to Bolster Democracy, Not Undermine It

I strongly believe AI tools that engage citizens directly in shaping policy will be the main engine of future political campaigns. We’re familiar by now with stories about AI influencing voters’ opinions. What’s new here is the use of AI to shape a political party’s principles and policies and making such tools open and usable (…)

Webinaire: Cybermenaces contre les entreprises: comment faire face en 2026?

Le dernier rapport de l’Office fédéral de la cybersécurité indique une personnalisation et une sophistication des cyberattaques visant les entreprises et les particuliers en Suisse. Quelles sont les menaces les plus dangereuses qui ciblent l’économie? Comment les prévenir? Et comment bien former son personnel face à ces attaques? Giuseppe Bianco, Head Cash Management chez UBS et Olivier Crochat, directeur exécutif du Center for Digital Trust (C4DT) de l’EPFL en débattront avec Anouch Seydtaghia du journal Le Temps.

Swiss Internet Governance Forum

The Swiss IGF 2026 will take place on Tuesday, June 16 at Welle 7 in Bern. Bringing together government, private sector, civil society, and academia, the forum discusses internet governance and policy issues in a Swiss context, feeding into the broader global UN-led Internet Governance Forum. C4DT is pleased to announce that we will be organizing a session at this year’s Swiss IGF annual conference: “Digitalization and Democracy: Friends or Foes?”

Book Review “On Privacy and Technology”, by Solove, Daniel J. (2025)

In “On Privacy and Technology”, Prof. Solove distils years of rigorous academic research into an accessible analysis that cuts through the noise surrounding privacy debates with surgical precision. What makes this work particularly compelling is Solove’s unflinching exposure of uncomfortable truths: the consent model is fundamentally flawed, self-regulation has failed and cannot succeed, and current (…)

Technology Paternalism Expands — A Case for Self-Sovereign Identity

Finally, the term I’ve been looking for! Technology paternalism: when technical systems shape, restrict, or pre-decide our choices before we can make them. What strikes me most about this concept is how it finds echoes in so many current political debates—collective goals (safety, security, efficiency) versus individual choice; autonomy versus dependency; who holds power and (…)

Reshuffle: Who wins when AI restacks the knowledge economy (2025)

Choudary, Sangeet Paul (2025) Reshuffle: Who wins when AI restacks the knowledge economy (ISBN-13: ‎979-8294127213), Independently published, 460 pages. By Olivier Crochat “AI’s value lies less in automating tasks and more in enabling new coordination and decision-making architectures.” In his book Reshuffle, Choudary offers a compelling framework for leaders to navigate the organisational impact of (…)

How Google Maps is shaping where we eat – video

If you’ve ever looked to Google Maps for inspiration on where to eat and wondered why a restaurant that you know exists didn’t show up, this video breaks it down for you. What resonates with me is the gap the journalist’s investigation lays bare between what people value (food quality, customer service) and what Google’s (…)

Swiss Crypto Day

The Swiss Crypto Day is an informal event to promote research in cryptology in Switzerland. In 2026, the sixth edition will be held on September 4th in Zürich. More info will follow soon.

A photo of Iran’s bombed schoolgirl graveyard went viral. Why did AI say it wasn’t real?

The spread of deepfakes, erosion of trust in authentic images and hallucinating chatbots are today well-known issues. These phenomena are especially problematic in rapidly evolving situations, when people are looking for updates, but reliable information is not yet available. Add algorithmic content distribution to the mix, and you get a perfect storm of misinformation. While (…)

Google: 17,1 Millionen US-Dollar im Bug-Bounty-Programm 2025 ausgezahlt

Google startete schon 2010 ein ‘Vulnerability Reward Program’, ein Bug-Bounty für alle Services von Google, das Belohnungen auszahlt, allein 17 Millionen US-$ 2025. Dieser Betrag wurde an mehr als 700 Analysten verteilt, die Fehler in Android, der Google Cloud, aber auch in verbreiteten und häufig gebrauchten Open Source Programmen und Bibliotheken fanden. Auch wenn 17 (…)

From Ukraine to Iran, Hacking Security Cameras Is Now Part of War’s ‘Playbook’

The camera hacking issue is problematic because it weaponizes civilian devices without owners’ consent, creating an accountability gap where victims can’t control the security of cameras used against them. It democratizes military intelligence by replacing expensive satellites with cheap consumer cameras,and is nearly impossible to solve since millions of unpatched devices exist worldwide. Most fundamentally, (…)

Proton Mail Helped FBI Unmask Anonymous ‘Stop Cop City’ Protester

This article fascinates me because it exposes Proton Mail’s privacy limits under Swiss law. While Swiss law shields direct foreign access, Mutual Legal Assistance Treaties (MLAT) enables indirect cooperation—Swiss firms must disclose available metadata like payment data. This reveals limitations in what Switzerland’s privacy protections can shield users from in cross-border investigations.

Human Rights Week: Digital Frontlines

Human Rights Week is a 3-day congress exploring the dual impact of digital tools: empowering activism while enabling new forms of control. Participants examine how technology is transforming human rights and envision a more just digital future. Dr Olivier Crochat, C4DT’s executive director, will join a panel on digital platforms’ role in contemporary conflicts.

Spain launches tool to monitor online hate speech

I like the idea behind this tool because it tackles a serious online societal problem. I’m curious if and how it will pass the test of time. The key challenge will be to link subjective criteria to objective metrics – a problem we’ve seen with privacy, which still lacks objective benchmarks despite substantial research. But (…)

AI Agents Can Unmask Anonymous Online Identities

This article caught my attention because it exposes the threat of de-anonymization that AI agents pose and its consequences for online privacy. The author writes that ‘the implications stretch far beyond embarrassing social media reveals’ and points out that whistleblowers who reveal corporate misconduct and government corruption, journalists who shield their informants, and political dissidents (…)

India’s tech sovereignty is built on digital dependence

This analysis of India’s technological dependence reveals patterns that are also applicable to Europe. Attracting foreign tech companies to invest locally ultimately results in profits being exported abroad, exemplifying a kind of digital colonialism. In my opinion, the solution lies in a demand-side strategy that favors local and open-source products over monopolies such as Microsoft (…)
