US cyber defense chief accidentally uploaded secret government info to ChatGPT

Ars Technica — 28/01/2026

David's take

"

Apparently, it happens even to the best of us — even seasoned professionals with over 24 years of IT experience and a 'deep understanding of both the complexities and practical realities of infrastructure security!' Jokes aside, this incident is fascinating: it exposes elite-level lapses in AI tool governance despite regulatory warnings, underscoring the enduring risks to data sovereignty when sensitive information is fed into public AI chatbots.

EU tech chief sounds alarm over dependence on foreign tech

Politico — 27/01/2026

Katherine's take

"

The volatile start to 2026 has shaken the foundation of global digital trust. Digital sovereignty has always been a running theme in the background of European conversations around tech, but this year, it is likely to be front and center, as governments and businesses scramble to seek digital solutions that provide reliable data security and privacy protection for its citizens, clients, and users, regardless of the geopolitical drama of the week. Virkunnen’s specific calling out of chips is somewhat surprising, given how far away Europe is from chip autonomy, but developing more control over selected parts of the semiconductor value chain could be a feasible strategic move.

Big Tech is racing to own Africa’s internet

Rest of World — 21/01/2026

Olivier's take

"

This article highlights a crucial reality: basic connectivity must exist before any digital transformation can take place. With only 38% of the population online, Africa's digital divide represents both a massive challenge and an opportunity. It is fascinating to observe the competition between space-based solutions (Starlink, Amazon Leo) and submarine cables (Meta's 2Africa, Google's Equiano). Notably absent: China. Given Beijing's substantial infrastructure investments across Africa, their absence from this connectivity race is worthy of monitoring for its potential geopolitical implications.

Hundreds of Millions of Audio Devices Need a Patch to Prevent Wireless Hacking and Tracking

WIRED — 15/01/2026

Stéphanie's take

"

Researchers at KU Leuven disclosed flaws in Google’s Fast Pair Bluetooth protocol that let attackers within Bluetooth range silently pair with seventeen different models of headphones or speakers made by ten different vendors, including Sony, Xiaomi, and even Google itself. This set of vulnerabilities enables cheap, practical hijacking, eavesdropping, and tracking of millions of earbuds and speakers—even of non-Android users, and exposes weak ownership/authentication, failed certification checks, and slow, uneven patching for IoT devices.

AI’s Memorization Crisis

Schneier on Security — 09/01/2026

Carine's take

"

The inclusion of copyrighted materials in LLMs' training data has been a hot-button issue from the get-go. In the beginning, Big Tech's reassurances that their models' inner workings prevented such material to be stored, let alone accessible, were convincing enough. But new research is painting a different picture, landing the companies in hot legal waters. This article traces the history of related court cases in the U.S. and puts them into context of the latest research on the matter.

10 February 2026: AMLD Intelligence Summit 2026, C4DT track “Assessing the Disruption by AI Agents: Economic, Security and Legal Perspectives”

 

Where? Auditorium A, SwissTech Convention Center (STCC), EPFL in Lausanne, Switzerland

 

Time? 14h00-15h30 (CET)

 

Why participate?
As we enter the agentic era, AI agents are increasingly integrated into various aspects of modern life, performing tasks that range from personal assistance and financial management to complex decision-making in industries. These AI agents, driven by powerful algorithms, are transforming how we interact with technology and each other. However, their proliferation also introduces significant challenges, such as cybersecurity vulnerabilities, economic and business disruptions, ethical dilemmas, and privacy concerns. This conference aims to delve into how AI agents could challenge existing systems and structures while exploring strategies to mitigate these threats effectively. Industry leaders, researchers, policymakers, and stakeholders will convene to discuss the implications of AI agents and collaborate on building a resilient future that harnesses their potential responsibly.

 

This track is organized by the Center for Digital Trust (C4DT), EPFL.

11 February 2026: AMLD Intelligence Summit 2026, C4DT track “AI & Media, how to secure and verify info?“

 

Where? Auditorium A, SwissTech Convention Center (STCC), EPFL in Lausanne, Switzerland

 

Time? 14h00-15h30 (CET)

 

Why participate?
AI empowers journalists by rapidly accessing and analyzing vast document sets, but it also brings risks: it can be misused to unmask anonymous sources or to fabricate convincing misinformation. Without strong governance, AI may hallucinate, creating false or defamatory claims. In this track we highlight the needs and tools for robust safeguards to ensure AI strengthens, not undermines, integrity in journalism.
