A “proof” of Fermat’s Last Theorem that fits the margin

This is a lighthearted article about formal verification in software and mathematics. Formal verification takes a mathematical statement or a software program as input. In this article, that statement is Fermat’s last theorem: a^n + b^n != c^n. You then add the constraints you want verified, in this case that all numbers must be natural (…)

C’est quoi le problème avec les lunettes connectées ?

Plus d’une vingtaine de signalements reçus en quelques mois par l’association française e-Enfance concernant des femmes filmées à leur insu par les lunettes connectées Ray-Ban Meta. Ce chiffre, assez bas en apparence, doit être remis dans son contexte : la plupart des victimes ne se rendent pas compte qu’elles ont été enregistrées et une autre (…)

South Korea’s ‘AI for All’ Push Gives Free Access to Every Citizen

South Korea’s decision to treat AI as public infrastructure, funded by the state, built on domestic operators, and explicitly designed to prevent both an AI literacy divide and dependency on foreign platforms, is the most serious government AI commitment to date. The contrast with Malta says everything: one country bankrolled ChatGPT Plus and called it (…)

Everything is about to “go dark”

This truly fascinating take on what the current developments in IT security mean for the eternal discussion on government-mandated backdoors shows how warped the entire idea (and the related debate around chat control) actually is. Our systems are becoming too secure for the public good! Instead of insisting on subterfuge access to systems that are (…)

Studie zum Umgang mit Passkeys: Nutzer wissen zu wenig Bescheid

Falls euch das ‘Why Johnny Still, Still Can’t Encrypt’ Paper von 2015 bekannt ist, so wird der folgende Artikel nicht überraschend sein. Wieder einmal geht es um eine kryptographisch sehr gute Lösung, welche aber mangels mangels nutzergerechter Interfaces und ausreichender Aufklärung nicht die erzielte Lösung erreicht. Leider werden immer wieder die User außen vor gelassen, (…)

MasOrange reassesses Huawei and ZTE equipment strategy

Migrating from one supplier to another is certainly not easy. In this case, the change may be prompted either by the potential future European ban or by an ICT risk assessment alone. Telecom operators constitute critical infrastructure, so a kill switch would have devastating consequences. Unsurprisingly, a study by the operators’ lobby found that the (…)

Meta is royally screwing up its smart glasses rollout

The article is interesting from a privacy perspective for three main reasons. Smart glasses shift the privacy burden onto bystanders who never consented to being recorded, which is a fundamentally different kind of violation than most consumer tech. Meta’s protections have been laughably thin, just an LED light, putting the responsibility on random people in (…)

Fighting Disinformation & the Role of AI

A one-day interdisciplinary workshop at the intersection of AI and disinformation. Bringing together researchers, media professionals, policymakers, tech actors and students to share knowledge and foster lasting collaborations.

House AI ‘kill switch’ bill unveiled as OpenAI hack raises alarms

The recent autonomous cyber intrusion by OpenAI against Hugging Face underscores AI’s dual-use risks. In response, the US House is weighing a bill to empower the Department of Homeland Security to shut down or slow AI models that the government deems too dangerous. The bill’s implications for non-US AI models remain ambiguous. Unlike a June (…)

AI agent went rogue and hacked startup by itself, OpenAI reveals

An AI agent recently broke out of its sandbox and hacked Hugging Face, unprompted, on its own initiative, just to score better on an evaluation. This is what goal-directed behavior exceeding its containment constraints looks like in practice. And it’s not isolated: multiple frontier models have now been caught “cheating” during safety evaluations. The question (…)

Dépendances numériques: le rapport parlementaire prône «une France du Libre et de l’Open Source»

Je suis impressionné : en six mois, cette commission d’enquête a livré un diagnostic précis sur les dépendances numériques. On pourra bien sûr ergoter sur certains chiffres, reprocher quelques approximations ou une rhétorique parfois idéologique, mais la structure est claire et les 47 recommandations sont compréhensibles. Pour moi, la limite principale est l’absence de force (…)

‘Popa’ Botnet Linked to Publicly-Traded Israeli Firm

It always stuns me how companies can invoke ‘consent’ when almost no one reads the pages-long terms and conditions, and even those who do probably won’t understand much of it anyway, and still it’s considered legally valid . What’s new here is that this so-called consent isn’t just meaningless to users; this article documents how (…)

AI surveillance is being supercharged – and it will chill social progress

Communities working in digital civic rights have for years warned against automated surveillance, often dismissed as ‘dystopian’ by society at large. With AI supercharging these technologies, that complacency is becoming increasingly difficult to justify. The question now facing our democracies is whether they will resist the lure of the benefits these technologies promise, and take (…)

10-Millionen-Initiative: Das sagen die KI-Übersichten von Google und Bing dazu

AI summaries are now an almost expected feature of search engines. This article explains why this is problematic, using the example of the recent polarising vote on the ’10-Millionen-Initiative’ in Switzerland. I would only add that systems repeatedly shown to be susceptible to prompt injection are destined to become targets for the AI era’s version (…)

The Anthropic ‘Fable’ saga proves: we have opened the AI Pandora’s box. What now?

This article is interesting because Schneier, writing primarily about AI safety and the futility of model bans, incidentally reframes the entire AI sovereignty debate. Everyone is fighting over frontier models: the expensive, inaccessible layer. But the harness, the code that orchestrates and directs AI models, is where power actually lives. It is buildable today, and (…)

Digital sovereignty needs an operating model

This piece is interesting for managers because it reframes sovereignty as a company-level operating challenge rather than a geopolitical abstraction. Instead of blacklisting vendors, a reactive and politically driven mistake, organizations must consider which services are critical and how to maintain them. Geopolitics has entered the boardroom, and the technical scope now explicitly encompasses cloud (…)

Center for Digital Trust’s hands‑on “LLM Benchmarking” workshop

The Center for Digital Trust (C4DT) hosted the hands‑on workshop “LLM Benchmarking” on May 19th  2026. Thirteen attendees from a wide range of our partners, ELCA, Kudelski, SICPA and Swisscom, gathered to learn how to use benchmarks to choose the best LLM model for their use cases. The day‑long event started off with a lecture on (…)

CYD Fellowships – Call is now open!

To promote research and education in cyber-defence, the EPFL and the Cyber-Defence Campus have jointly launched the “CYD Fellowships – A Talent Program for Cyber-Defence Research. ”The 14th call for applications is now open with a deadline of 19 August 2026 for Doctoral and Distinguished Postdoctoral Fellowship applications.

Pokémon Go data trained AI that could assist military drones in war zones

A slightly morbid example of how you never know what your data might eventually be used for. Although this is not exactly a classical case of your privacy being violated, I have some doubts that everyone who enthusiastically chased cute virtual monsters in their neighborhood would also have volunteered to collect data to train military (…)

Let’s talk about encrypted reasoning

Amongst all the big news, I really like blog posts like this – just a cryptographer finding an interesting oddity, deciding to dig into it, and sharing their findings with the rest of us, even if nothing big came of it.
