AI fuels a new wave of cyber threats in Greece

Greece is confronting a rapid rise in cybercrime as AI strengthens the tools available to criminals, according to the head of the National Cyber Security Authority.

Michael Bletsas warned that Europe is already experiencing hybrid conflict, with Northeastern states facing severe incidents that reveal a digital frontline. Greece has not endured physical sabotage or damage to its infrastructure, yet cyberattacks remain a pressing concern.

Bletsas noted that most activity involves cybercrime instead of destructive action. He pointed to the expansion of cyberactivism and vandalism through denial-of-service attacks, which usually cause no lasting harm.

The broader problem stems from a surge in AI-driven intrusions and espionage, which offer new capabilities to malicious groups and create a more volatile environment.

Moreover, Bletsas said that the physical and digital worlds should be viewed as a single, interconnected sphere, with security designed around shared principles rather than being treated as separate domains.

Digital warfare is already unfolding, and Greece is part of it. The country must now define its alliances and strengthen its readiness as cyber threats intensify and the global divide grows deeper.

Taiwan blocks Chinese app RedNote after surge in online scams

Authorities in Taiwan will block the Chinese social media and shopping app RedNote for a year following a surge in online scams linked to the platform. Officials report that more than 1,700 fraud cases have been linked to the app since last year, resulting in losses exceeding NT$247 million.

Regulators report that the company failed to meet required data-security standards and did not respond to requests for a plan to strengthen cybersecurity.

Internet providers have been instructed to restrict access, affecting several million users who now see a security warning message when opening the app.

Concerns over Beijing’s online influence and the spread of disinformation have added pressure on Taiwanese authorities to tighten oversight of Chinese platforms.

RedNote’s operators are also facing scrutiny in mainland China, where regulators have criticised the company over what they labelled ‘negative’ content.

Europe builds a laser ground station in Greenland to protect satellite links

Europe is building a laser-based ground station in Greenland to secure satellite links as Russian jamming intensifies. ESA and Denmark chose Kangerlussuaq for its clear skies and direct access to polar-orbit traffic.

The optical system uses Astrolight’s technology to transmit data markedly faster than radio signals. Narrow laser beams resist interference, allowing vast imaging sets to reach analysts with far fewer disruptions.

Developers expect terabytes to be downloaded in under a minute, reducing reliance on vulnerable Arctic radio sites. European officials say the upgrade strengthens autonomy as undersea cables and navigation systems face repeated targeting from countries such as Russia.

The Danish station will support defence monitoring, climate science and search-and-rescue operations across high latitudes. Work is underway, with completion planned for 2026 and ambitions for a wider global laser network.

NSA warns AI poses new risks for operational technology

The US National Security Agency (NSA), together with international partners including Australia’s ACSC, has issued guidance on the secure integration of AI into operational technology (OT).

The Principles for the Secure Integration of AI in OT warn that while AI can optimise critical infrastructure, it also introduces new risks for safety-critical environments. Although aimed at OT administrators, the guidance also highlights issues relevant to IT networks.

AI is increasingly deployed in sectors such as energy, water treatment, healthcare, and manufacturing to automate processes and enhance efficiency.

The NSA’s guidance, however, flags several potential threats, including adversarial prompt injection, data poisoning, AI drift, and reduced explainability, all of which can compromise safety and compliance.

Over-reliance on AI may also lead to human de-skilling, cognitive overload, and distraction, while AI hallucinations raise concerns about reliability in safety-critical settings.

Experts emphasise that AI cannot currently be trusted to make independent safety decisions in OT networks, where the margin for error is far smaller than in standard IT systems.

Sam Maesschalck, an OT engineer, noted that introducing AI without first addressing pre-existing infrastructure issues, such as insufficient data feeds or incomplete asset inventories, could undermine both security and operational efficiency.

The guidance aims to help organisations evaluate AI risks, clarify accountability, and prepare for potential misbehaviour, underlining the importance of careful planning before deploying AI in operationally critical environments.

Google drives health innovation through new EU AI initiative

At the European Health Summit in Brussels, Google presented new research suggesting that AI could help Europe overcome rising healthcare pressures.

The report, prepared by Implement Consulting Group for Google, argues that scientific productivity is improving again, rather than continuing a long period of stagnation. Early results already show shorter waiting times in emergency departments, offering practitioners more space to focus on patient needs.

Momentum at the Summit increased as Google announced new support for AI adoption in frontline care.

Five million dollars from Google.org will fund Bayes Impact to launch an EU-wide initiative known as ‘Impulse Healthcare’. The programme will allow nurses, doctors and administrators to design and test their own AI tools through an open-source platform.

By placing development in the hands of practitioners, the project aims to expand ideas that help staff reclaim valuable time during periods of growing demand.

Successful tools developed at a local level will be scaled across the EU, providing a path to more efficient workflows and enhanced patient care.

Google views these efforts as part of a broader push to rebuild capacity in Europe’s health systems.

AI-assisted solutions may reduce administrative burdens, support strained workforces and guide decisions through faster, data-driven insights, strengthening everyday clinical practice.

€700 million crypto fraud network spanning Europe broken up

Authorities have broken an extensive cryptocurrency fraud and money laundering network that moved over EUR 700 million after years of international investigation.

The operation began with an investigation into a single fraudulent cryptocurrency platform and eventually uncovered an extensive network of fake investment schemes targeting thousands of victims.

Victims were drawn in by fake ads promising high returns and pressured via criminal call centres to pay more. Transferred funds were stolen and laundered across blockchains and exchanges, exposing a highly organised operation across Europe and beyond.

Police raids across Cyprus, Germany, and Spain in late October 2025 resulted in nine arrests and the seizure of millions in assets, including bank deposits, cryptocurrencies, cash, digital devices, and luxury watches.

Europol and Eurojust coordinated the cross-border operation with national authorities from France, Belgium, Germany, Spain, Malta, Cyprus, and other nations.

The second phase, executed in November, targeted the affiliate marketing infrastructure behind fraudulent online advertising, including deepfake campaigns impersonating celebrities and media outlets.

Law enforcement teams in Belgium, Bulgaria, Germany, and Israel conducted searches, dismantling key elements of the scam ecosystem. Investigations continue to track down remaining assets and dismantle the broader network.

Russia blocks Snapchat and FaceTime access

Russia’s state communications watchdog has intensified its campaign against major foreign platforms by blocking Snapchat and restricting FaceTime calls.

The move follows earlier reports of disrupted Apple services inside the country, while users could still connect through VPNs instead of relying on direct access. Roskomnadzor accused Snapchat of enabling criminal activity and repeated earlier claims targeting Apple’s service.

A decision that marks the authorities’ first formal confirmation of limits on both platforms. It arrives as pressure increases on WhatsApp, which remains Russia’s most popular messenger, with officials warning that a whole block is possible.

Meta is accused of failing to meet data-localisation rules and of what the authorities describe as repeated violations linked to terrorism and fraud.

Digital rights groups argue that technical restrictions are designed to push citizens toward Max, a government-backed messenger that activists say grants officials sweeping access to private conversations, rather than protecting user privacy.

These measures coincide with wider crackdowns, including the recent blocking of the Roblox gaming platform over allegations of extremist content and harmful influence on children.

The tightening of controls reflects a broader effort to regulate online communication as Russia seeks stronger oversight of digital platforms. The latest blocks add further uncertainty for millions of users who depend on familiar services instead of switching to state-supported alternatives.

Japanese high-schooler suspected of hacking net-cafe chain using AI

Authorities in Tokyo have issued an arrest warrant for a 17-year-old boy from Osaka on suspicion of orchestrating a large-scale cyberattack using artificial intelligence. The alleged target was the operator of the Kaikatsu Club internet-café chain (along with related fitness-gym business), which may have exposed the personal data of about 7.3 million customers.

According to investigators, the suspect used a computer programme, reportedly built with help from an AI chatbot, to send unauthorised commands around 7.24 million times to the company’s servers in order to extract membership information. The teenager was previously arrested in November in connection with a separate fraud case involving credit-card misuse.

Police have charged him under Japan’s law against unauthorised computer access and for obstructing business, though so far no evidence has emerged of misuse (for example, resale or public leaks) of the stolen data.

In his statement to investigators, the suspect reportedly said he carried out the hack simply because he found it fun to probe system vulnerabilities.

This case is the latest in a growing pattern of so-called AI-enabled cyber crimes in Japan, from fraudulent subscription schemes to ransomware generation. Experts warn that generative AI is lowering the barrier to entry for complex attacks, enabling individuals with limited technical training to carry out large-scale hacking or fraud.

Google boosts Nigeria’s AI development

The US tech giant, Google, has announced a $2.1 million Google.org commitment to support Nigeria’s AI-powered future, aiming to strengthen local talent and improve digital safety nationwide.

An initiative that supports Nigeria’s National AI Strategy and its ambition to create one million digital jobs, recognising the economic potential of AI, which could add $15 billion to the country’s economy by 2030.

The investment focuses on developing advanced AI skills among students and developers instead of limiting progress to short-term training schemes.

Google will fund programmes led by expert partners such as FATE Foundation, the African Institute for Mathematical Sciences, and the African Technology Forum.

Their work will introduce advanced AI curricula into universities and provide developers with structured, practical routes from training to building real-world products.

The commitment also expands digital safety initiatives so communities can participate securely in the digital economy.

Junior Achievement Africa will scale Google’s ‘Be Internet Awesome’ curriculum to help families understand safe online behaviour, while the CyberSafe Foundation will deliver cybersecurity training and technical assistance to public institutions, strengthening national digital resilience.

Google aims to create more opportunities similar to those of Nigerian learners who used digital skills to secure full-time careers instead of remaining excluded from the digital economy.

By combining advanced AI training with improved digital safety, the company intends to support inclusive growth and build long-term capacity across Nigeria.

SAP elevates customer support with proactive AI systems

AI has pushed customer support into a new era, where anticipation replaces reaction. SAP has built a proactive model that predicts issues, prevents failures and keeps critical systems running smoothly instead of relying on queues and manual intervention.

Major sales events, such as Cyber Week and Singles Day, demonstrated the impact of this shift, with uninterrupted service and significant growth in transaction volumes and order numbers.

Self-service now resolves most issues before they reach an engineer, as structured knowledge supports AI agents that respond instantly with a confidence level that matches human performance.

Tools such as the Auto Response Agent and Incident Solution Matching enable customers to retrieve solutions without having to search through lengthy documentation.

SAP has also prepared organisations scaling AI by offering support systems tailored for early deployment.

Engineers have benefited from AI as much as customers. Routine tasks are handled automatically, allowing experts to focus on problems that demand insight instead of administration.

Language optimisation, routing suggestions, and automatic error categorisation support faster and more accurate resolutions. SAP validates every AI tool internally before release, which it views as a safeguard for responsible adoption.

The company maintains that AI will augment staff rather than replace them. Creative and analytical work becomes increasingly important as automation handles repetitive tasks, and new roles emerge in areas such as AI training and data stewardship.

SAP argues that progress relies on a balanced relationship between human judgement and machine intelligence, strengthened by partnerships that turn enterprise data into measurable outcomes.
