It often appears as if disinformation was spread by a large number of social media users. However, research suggests that it is a comparatively small percentage of the users that is primarily responsible for creating and widely sharing divisive content, with these voices being amplified by the platforms’ algorithms. As bleak as this may be, (…)
With all the hype around agentic AI, the industry is rushing to embrace it. However, alarm bells have been sounded again and again concerning misaligned behaviour of LLMs and Large Reasoning Models (LRMs), ranging from ‘harmless’ misinformation to deliberately malicious actions. This raises serious questions whether the current technology is really mature enough to be (…)
This year’s Cyber-Defence Campus Conference will take place on Wednesday, 29 October 2025, at the Kursaal Bern. The main theme of the conference is ‘The Role of Cyber in Conflicts and (Hybrid) Warfare’. We look forward to welcoming experts and interested parties from government, industry and academia to this conference.
A must-attend event in Switzerland, the Black Alps conference is a hot spot for cybersecurity professionals and enthusiasts. The event allows you to discuss the latest threats, mitigations and advances in cybersecurity. The 2-day and 2-night program includes a variety of keynotes and technical talks, networking dinners and an ethical hacking contest (CTF). #BlackAlps25
Severe floods in Texas sparked a wave of conspiracy theories, with claims circulating online that the disaster was caused by geoengineering or weather weapons. This highlights a growing tension between the speed at which formal institutions can communicate accurate information and the rapid spread of AI-fueled disinformation. The resulting vandalism of radar infrastructure and threats (…)
A lot of cryptographic proofs rely on something called the ‘random oracle model’ and the ‘Fiat-Shamir transformation’. Together, they can create a mathematical proof of the security of a specific zero knowledge protocol. However, the random oracle model is never used – in real algorithms, it is replaced by a hash function. What can go (…)
As a software engineer, I’m looking at LLMs both as a tool for, but potentially also a danger to, my job: will it replace me one day? In this study, they measured the time that seasoned software needed to fix a bug, both with and without the aid of LLMs. The outcome in this specific (…)
C4DT collaborated with NCSC on implementation of Motion 23.3002. It organized the first of a series of three workshops, actively participated in two additional workshops, and delivered a summary of the workshop results from C4DT’s perspective for the final report.”
Am Beispiel deutscher Medien wird die Entwicklung des Online-Journalismus seit den 90ern bis heute nachvollzogen. Besonders interessant finde ich die Diskussion der jeweiligen Problematiken denen die Verlage im Web 1.0, in den sozialen Medien und heute mit generativer AI konfrontiert sind/waren.
Dieser Beitrag erläutert anschaulich am Beispiel des jüngsten Datenleaks der Schweizer Bundespolitiker:innen warum wir als Gesellschaft solche Leaks nicht bagatellisieren sollten.
There has been a lot of discussion about the high cost of cyber-attacks, and the recent announcement that the credentials of Swiss parliamentarians are circulating on the Darknet serves as a reminder of this. Interestingly, stolen access credential is the main intrusion vector (16%) in companies and remains undetected for the longest time (an average (…)
The Center for Digital Trust hosted a successful workshop on Privacy-Preserving eID last week. We welcomed 14 participants from seven partner organizations including Be-Ys, ELCA, FOITT, Kudelski, SICPA, Swiss Post/SwissSign, and Swisscom. The day-long event combined theoretical foundations with hands-on technical demonstrations. Our focus centered on swiyu, Switzerland’s proposed eID project developed by FOITT, (…)
This report reveals new vulnerabilities in the equipment used in solar power grids and smart homes. It shows that attackers can exploit flaws in the supply chain and insecure protocols to disrupt power generation or grid stability. Clear infographics illustrate the network structure, risks and the worldwide share of solar use. As solar energy continues (…)
This essay stands out because it moves beyond sensational fears about AI replacing humans and instead offers a practical framework for understanding when AI genuinely outperforms humans and when human skills remain irreplaceable… (at least for now).
This article highlights significant flaws within the proposed NO FAKES Act, whose repercussions would extend far beyond U.S. borders. I found it particularly insightful because of the parallels it draws between this bill and existing mechanisms for addressing copyright infringement, outlining how the deficiencies within the latter are likely to be mirrored in the former.
Driven by ethical concerns about using existing artwork to train gen AI models, an artist created his own model that produces output untrained on any data at all. What was interesting to me is that, in exploring whether gen AI could create original art, he also demonstrated a potential path to better understanding how such (…)

Images façon “studio Ghibli”, tendance Starter Pack. derrière leur aspect ludique, ces images générées par l’intelligence artificielle générative posent des questions environnementales très concrètes. Réponses avec Babak Falsafi, professeur ordinaire à la faculté d’Informatique et de Communications de l’EPFL, président et fondateur de l’Association suisse pour l’efficacité énergétique dans les centres de données (SDEA).
Cycle tracking apps are not only helpful for those trying to conceive, but also serve as important tools for keeping track of one’s general reproductive health. As this article discusses, however, such tools can quickly become a double-edged sword due to the high value of the data they collect, which can potentially end up in (…)
This article underscores that neither digital policies nor technologies can be discussed in isolation. Using Indonesia as an example, it lays out how the country’s laws and regulations on internet content are actually implemented by the ISPs and examines how the combination of vaguely worded laws and sweeping filtering methods ultimately impacts citizens’ access to (…)
This article is interesting because it highlights the opportunities and challenges of personal data ownership. Although tools such as dWallet claim to empower users, they can encourage the poorest and least educated people to sell their data without understanding the risks, thereby widening the digital divide. True data empowerment means that everyone must have the (…)
To foster wallets, credentials and trusted infrastructure for the benefit of all humans. Leading organizations from across the globe coming together to shape the future of digital identity, in particular in the realm of secure, interoperable wallets, credentials and trusted infrastructure.
That is a very nice attack on privacy-protection in the mobile browsers: even if you don’t allow any cookies and don’t consent on being tracked, you’re browsing behaviour is still tracked. The idea of communicating from the mobile browser to your locally installed app is technically very interesting, and seems to be difficult to avoid (…)
Cybercriminals are using U.S. cloud providers like AWS and Azure to hide their activities, creating an “infrastructure laundering” trend that complicates cybersecurity. The whac-a-mole responses highlight the urgent need for better coordination and reveal that current strategies can’t keep up with criminals’ quick adaptation and evasion tactics.
