EU cyber rules target global tech dependence

The European Union has proposed new cybersecurity rules aimed at reducing reliance on high-risk technology suppliers, particularly from China. In the European Union, policymakers argue existing voluntary measures failed to curb dependence on vendors such as Huawei and ZTE.

The proposal would introduce binding obligations for telecom operators across the European Union to phase out Chinese equipment. At the same time, officials have warned that reliance on US cloud and satellite services also poses security risks for Europe.

Despite increased funding and expanded certification plans, divisions remain within the European Union. Countries including Germany and France support stricter sovereignty rules, while others favour continued partnerships with US technology firms.

Analysts say the lack of consensus in the European Union could weaken the impact of the reforms. Without clear enforcement and investment in European alternatives, Europe may struggle to reduce dependence on both China and the US.

WEF paper warns of widening AI investment gap

Policy-makers are being urged to take a more targeted approach to ‘sovereign AI’ spending, as a new paper released alongside the World Economic Forum meeting in Davos argues that no country can realistically build every part of the AI stack alone. Instead, the authors recommend treating AI sovereignty as ‘strategic interdependence’, combining selective domestic investment with trusted partnerships and alliances.

The paper, co-authored by the World Economic Forum and Bain & Co, highlights how heavily the United States and China dominate the global AI landscape. It estimates that the two countries capture around 65% of worldwide investment across the AI value chain, reflecting a full-stack model, from chips and cloud infrastructure to applications, that most other economies cannot match at the same scale.

For smaller and mid-sized economies, that imbalance can translate into a competitive disadvantage, because AI infrastructure, such as data centres and computing capacity, is increasingly viewed as the backbone of national AI capability. Still, the report argues that faster-moving countries can carve out a niche by focusing on a few priority areas, pooling regional capacity, or securing access through partnerships rather than trying to replicate the US-China approach.

The message was echoed in Davos by Nvidia chief executive Jensen Huang, who said every country should treat AI as essential infrastructure, comparable to electricity grids and transport networks. He argued that building AI data centres could drive demand for well-paid skilled trades, from electricians and plumbers to network engineers, framing the boom as a major job creator rather than a trigger for widespread job losses.

At the same time, the paper warns that physical constraints could slow expansion, including the availability of land, energy and water, as well as shortages of highly skilled workers. It also notes that local regulation can delay projects, although some industry groups argue that regulatory and cost pressures may push countries to innovate sooner in efficiency and greener data-centre design.

In the UK, industry body UKAI says high energy prices, limited grid capacity, complex planning rules and public scrutiny already create the same hurdles many other countries may soon face. It argues these constraints are helping drive improvements in efficiency, system design and coordination, seen as building blocks for more sustainable AI infrastructure.

Rethinking the digital embassy concept

The term ‘digital embassy’ has been floating around for years, but it often adds more confusion than clarity. In his blog ‘What is a ‘digital embassy’? (Spoiler: It’s not an embassy)’, Jovan Kurbalija argues that the phrase is a misnomer in a field already crowded with overlapping labels like digital diplomacy, cyber diplomacy, and tech diplomacy.

The expression became popular after Estonia, in 2017, set up an offshore backup of national data on servers in Luxembourg under diplomatic protection. The idea was innovative, but Kurbalija stresses that a protected data vault is not an embassy in the traditional sense; it does not represent a country, negotiate on its behalf, or engage with the host society.

He points to the 1961 Vienna Convention on Diplomatic Relations, which defines an embassy as a state’s official presence on foreign territory, tasked with representation, negotiation, and the safeguarding of national interests. While states have experimented with online forms of presence, such as official websites or even ‘virtual embassies’ in platforms like Second Life, the core function remains political and relational, not simply technical.

Calling a remote server a ‘digital embassy,’ Kurbalija warns, can mislead the public and muddy policymaking. An embassy suggests diplomacy and interaction; a backup facility is about continuity, resilience, and the preservation of state records.

Estonia’s motivation, he notes, was shaped by history, specifically the fear of losing national archives and collective memory, echoing the 1940 seizure of records during Soviet control.

The push for more precise terminology may become even more important if these facilities evolve. A proposal raised during a World Economic Forum panel suggested adding AI-based processing capabilities to such offshore data sites, an idea that could shift them from passive storage toward something closer to strategic infrastructure linked to ‘AI sovereignty.’

Kurbalija suggests that instead of stretching the word ‘embassy,’ governments could borrow more precise historical concepts for protected foreign facilities, such as a ‘diplomatic enclave,’ ‘diplomatic funduq,’ or ‘diplomatic sanctuary.’ His broader point is that as countries invest in digital resilience and sovereignty, the language used to describe these arrangements should keep pace, because legitimacy and legal clarity often begin with accurate naming.

Ransomware attack on Under Armour leads to massive customer data exposure

Under Armour is facing growing scrutiny following the publication of customer data linked to a ransomware attack disclosed in late 2025.

According to breach verification platform Have I Been Pwned, a dataset associated with the incident appeared on a hacking forum in January, exposing information tied to tens of millions of customers.

The leaked material reportedly includes 72 million email addresses alongside names, dates of birth, location details and purchase histories. Security analysts warn that such datasets pose risks that extend far beyond immediate exposure, particularly when personal identifiers and behavioural data are combined.

Experts note that verified customer information linked to a recognised brand can enable compelling phishing and fraud campaigns powered by AI tools.

Messages referencing real transactions or purchase behaviour can blur the boundary between legitimate communication and malicious activity, increasing the likelihood of delayed victimisation.

The incident has also led to legal action against Under Armour, with plaintiffs alleging failures in safeguarding sensitive customer information. The case highlights how modern data breaches increasingly generate long-term consequences rather than immediate technical disruption.

New AI method boosts reasoning without extra training

Researchers at the University of California, Riverside, have introduced a technique that improves AI reasoning without requiring additional training data. Called Test-Time Matching, the approach enhances AI performance by enabling dynamic model adaptation.

The method addresses a persistent weakness in multimodal AI systems, which often struggle to interpret unfamiliar combinations of images and text. Traditional evaluation metrics rely on isolated comparisons that can obscure deeper reasoning capabilities.

By replacing these with a group-based matching approach, the researchers uncovered hidden model potential and achieved markedly stronger results.

Test-Time Matching lets AI systems refine predictions through repeated self-correction. Tests on SigLIP-B16 showed substantial gains, with performance surpassing larger models, including GPT-4.1, on key reasoning benchmarks.

The findings suggest that smarter evaluation and adaptation strategies may unlock powerful reasoning abilities even in smaller models. Researchers say the approach could speed AI deployment across robotics, healthcare, and autonomous systems.

Microsoft restores Exchange and Teams after Microsoft 365 disruption

The US tech giant, Microsoft, investigated a service disruption affecting Exchange Online, Teams and other Microsoft 365 services after users reported access and performance problems.

An incident that began late on Wednesday affected core communication tools used by enterprises for daily operations.

Engineers initially focused on diagnosing the fault, with Microsoft indicating that a potential third-party networking issue may have interfered with access to Outlook and Teams.

During the disruption, users experienced intermittent connectivity failures, latency and difficulties signing in across parts of the Microsoft 365 ecosystem.

Microsoft later confirmed that service access had been restored, although no detailed breakdown of the outage scope was provided.

The incident underlined the operational risks associated with cloud productivity platforms and the importance of transparency and resilience in enterprise digital infrastructure.

From chips to jobs: Huang’s vision for AI at Davos 2026

AI is evolving into a foundational economic system rather than a standalone technology, according to NVIDIA chief executive Jensen Huang, who described AI as a five-layer infrastructure spanning energy, hardware, data centres, models and applications.

Speaking at the World Economic Forum in Davos, Huang argued that building and operating each layer is triggering what he called the most significant infrastructure expansion in human history, with job creation stretching from power generation and construction to cloud operations and software development.

Investment patterns suggest a structural shift instead of a speculative cycle. Venture capital funding in 2025 reached record levels, largely flowing into AI-native firms across healthcare, manufacturing, robotics and financial services.

Huang stressed that the application layer will deliver the most significant economic return as AI moves from experimentation to core operational use across industries.

Concerns around job displacement were framed as misplaced. AI automates tasks rather than replacing professional judgement, enabling workers to focus on higher-value activities.

In healthcare, productivity gains from AI-assisted diagnostics and documentation are already increasing demand for radiologists and nurses rather than reducing headcount, as improved efficiency enables institutions to treat more patients.

Huang positioned AI as critical national infrastructure, urging governments to develop domestic capabilities aligned with local language, culture and industrial strengths.

He described AI literacy as an essential skill, comparable to leadership or management, while arguing that accessible AI tools could narrow global technology divides rather than widen them.

South Korea sets the global standard for frontier AI regulation

South Korea will begin enforcing its Artificial Intelligence Act on Thursday, becoming the first country to introduce formal safety requirements for high-performance, or frontier, AI systems, reshaping the global regulatory landscape.

The law establishes a national AI governance framework, led by the Presidential Council on National Artificial Intelligence Strategy, and creates an AI Safety Institute to oversee safety and trust assessments.

Alongside regulatory measures, the government is rolling out broad support for research, data infrastructure, talent development, startups, and overseas expansion, signalling a growth-oriented policy stance.

To minimise early disruption, authorities will introduce a minimum one-year grace period centred on guidance, consultation, and education rather than enforcement.

Obligations cover three areas: high-impact AI in critical sectors, safety rules for frontier models, and transparency requirements for generative AI, including disclosure of realistic synthetic content.

Enforcement remains light-touch, prioritising corrective orders over penalties, with fines capped at 30 million won for persistent noncompliance. Officials said the framework aims to build public trust while supporting innovation, serving as a foundation for ongoing policy development.

How Microsoft is shaping UN reform through digital infrastructure

Microsoft has announced a multi-year pledge to support the United Nations’ UN80 reform initiative, positioning AI and digital infrastructure as central tools for modernising multilateral governance.

The commitment follows agreement among all UN member states on efficiency and financial-stability measures, as the organisation faces growing operational demands amid constrained resources.

The initiative includes a dedicated innovation fund, preferential pricing for digital services, and free AI training for UN staff across agencies and missions.

Rather than focusing on policy direction, Microsoft frames its role as enabling institutional capacity, from procurement and logistics to humanitarian response and development planning, while encouraging other private-sector actors to align behind UN80 priorities.

Microsoft also plans to mobilise partners such as EY to support reform efforts, reinforcing a model where large technology firms contribute expertise, infrastructure, and coordination capacity to global governance systems.

Previous collaborations with UNICEF, UNHCR, ITU, and the ILO are cited as evidence that AI-driven tools can accelerate service delivery at scale.

The pledge highlights how multilateral reform increasingly depends on private technological ecosystems instead of purely intergovernmental solutions.

As AI becomes embedded in the core operations of international institutions, questions around accountability, influence, and long-term dependency are likely to shape debates about the future balance between public authority and corporate power.

WhatsApp faces growing pressure in Russia

Authorities in Russia are increasing pressure on WhatsApp, one of the country’s most widely used messaging platforms. The service remains popular despite years of tightening digital censorship.

Officials argue that WhatsApp refuses to comply with national laws on data storage and cooperation with law enforcement. Meta has no legal presence in Russia and continues to reject requests for user information.

State backed alternatives such as the national messenger Max are being promoted through institutional pressure. Critics warn that restricting WhatsApp targets private communication rather than crime or security threats.
