Europol backs major takedown of Cryptomixer in Switzerland

Europol has supported a coordinated action week in Zurich, where Swiss and German authorities dismantled the illegal cryptocurrency mixing service Cryptomixer.

Three servers were seized in Switzerland, together with the cryptomixer.io domain, leading to the confiscation of more than €25 million in Bitcoin and over 12 terabytes of operational data.

Cryptomixer operated on both the clear web and the dark web, enabling cybercriminals to conceal the origins of illicit funds. The platform has mixed over €1.3 billion in Bitcoin since 2016, aiding ransomware groups, dark web markets, and criminals involved in drug trafficking, weapons trafficking, and credit card fraud.

Its randomised pooling system effectively blocked the traceability of funds across the blockchain.

Mixing services, such as Cryptomixer, are used to anonymise illegal funds before moving them to exchanges or converting them into other cryptocurrencies or fiat. The takedown halts further laundering and disrupts a key tool used by organised cybercrime networks.

Europol facilitated information exchange through the Joint Cybercrime Action Taskforce and coordinated operational meetings throughout the investigation. The agency deployed cybercrime specialists on the final day to provide on-site support and forensics.

Earlier efforts included support for the 2023 takedown of Chipmixer, then the largest mixer of its kind.

Meta criticised for AI-generated adverts scams

Meta has faced criticism after numerous consumers reported being misled by companies using AI-generated adverts on Facebook and Instagram. The firms posed as UK businesses while shipping cheap goods from Asia, prompting claims that scams were ‘running rampant’ on the platforms.

Victims were persuaded by realistic adverts and AI-generated images but received poorly made clothing and jewellery. Several companies, including C’est La Vie, Mabel & Daisy, Harrison & Hayes, and Chester & Clare, were removed after investigations revealed fabricated backstories and fake shopfronts.

Consumer guides recommend vigilance, advising shoppers to check company websites, reviews, and use Trustpilot to verify legitimacy. Experts warn that overly perfect images, including AI-generated shopfronts or models, may signal fraudulent adverts.

Platforms such as Facebook and Instagram are urged to enforce stricter measures to prevent scams.

Meta stated it works with Stop Scams UK and encourages users to report suspicious adverts, while the Advertising Standards Authority continues to crack down on misleading online promotions.

South Korea retailer admits worst-ever data leak

Coupang disclosed a major data breach on 30 November 2025 that exposed 33.7 million customer accounts. The leaked data includes names, email addresses, phone numbers, shipping addresses and some order history but excludes payment or login credentials.

The company said it first detected unauthorised access on 18 November. Subsequent investigations revealed that attacks likely began on 24 June through overseas servers and may involve a former employee’s still-active authentication key.

South Korean authorities launched an emergency probe to determine if Coupang violated data-protection laws. The government warned customers to stay alert to phishing and fraud attempts using the leaked information.

Cybersecurity experts say the breach may be one of the worst personal-data leaks in Korean history. Critics claim the incident underlines deep structural weaknesses in corporate cybersecurity practices.

UK to require crypto traders to report details from 2026

The UK government has confirmed that cryptocurrency traders will be required to report personal details to trading platforms from 1 January 2026. The move forms part of the Cryptoasset Reporting Framework (CAFR), aligned with an OECD agreement, and aims to improve compliance with existing tax rules.

Under the framework, exchanges must provide HM Revenue & Customs (HMRC) with customer information, including cryptocurrency transactions and tax reference numbers.

Traders who fail to supply required details could face fines of up to £300, while platforms may be fined the same amount per unreported customer. HMRC expects to raise up to £315 million by 2030 from the new reporting rules.

Experts warn exchanges may face challenges collecting accurate information, potentially passing compliance costs onto users. Some investors may initially turn to noncompliant platforms, but international standards are expected to drive global alignment over time.

The 2025 Budget also addressed the taxation of DeFi activities such as lending and staking. HMRC appears to favour taxing gains only when they are realised, although no final decision has been made and consultations with stakeholders will continue.

DeepSeek opens access to gold-level maths AI

Chinese AI firm DeepSeek has released the first open AI model capable of achieving gold-medal results at the International Mathematical Olympiad. Math-V2 is now freely available on Hugging Face and GitHub, allowing developers to repurpose it and run it locally.

Gold-level performance at the IMO is remarkably rare, with only a small share of human participants reaching the top tier. DeepSeek aims to make such advanced mathematical capabilities accessible to researchers and developers who previously lacked access to comparable systems.

The company said its model achieved gold-level scores in both this year’s Olympiad and the Chinese Mathematical Olympiad. The results relied on strong theorem-proving skills and a new ‘self-verification’ method for reasoning without known solutions.

Observers said the open release could lower barriers to advanced maths AI, while US firms keep their Olympiad-level systems restricted. Supporters of open-source development welcomed the move as a significant step toward democratising advanced scientific tools.

Vanity Fair publisher penalised for cookie breaches

France’s data regulator fined Les Publications Condé Nast €750,000 for unlawful cookie practices on vanityfair.fr. Investigators found consent-based cookies loading immediately when visitors landed on the site.

CNIL officials also noted unclear information describing several trackers as strictly necessary without explaining their true purposes. Users faced further issues when refusal tools failed to block or halt consent-based cookies.

Repeated non-compliance weighed heavily, as the company had already received a formal order in 2021. Earlier proceedings had been closed after corrective steps, yet later inspections showed renewed breaches.

The French regulator stated that millions of visitors were potentially affected by the unlawful tracking activity. The case highlights continuing enforcement efforts under Article 82 of France’s Data Protection Act.

Concerns grow over WhatsApp rules as Italy probes Meta AI practices

Italy’s competition authority has launched an investigation into Meta over potential dominance in AI chatbots. Regulators are reviewing the new WhatsApp Business terms and upcoming Meta AI features. They say the changes could restrict rivals’ access to the platform.

Officials in Italy warn that the revised conditions may limit innovation and reduce consumer choice in emerging AI services. The concerns fall under Article 102 TFEU. The authority states that early action may be necessary to prevent distortions.

The case expands an existing Italian investigation into Meta and its regional subsidiaries. Regulators say technical integration of Meta AI could strengthen exclusionary effects. They argue that WhatsApp’s scale gives Meta significant structural advantages.

Low switching rates among users may entrench Meta’s market position further in Italy and beyond. Officials say rival chatbot providers would struggle to compete if access is constrained. They warn that competition could be permanently harmed.

Meta has announced significant new AI investments in the United States. Italian regulators say this reflects the sector’s growing influence. They argue that strong oversight is needed to ensure fair access to key platforms.

New digital strategy positions Uzbekistan as emerging AI hub

Uzbekistan has outlined an extensive plan to accelerate digital development by introducing new measures at major AI forums in Tashkent.

The leadership detailed a national effort to strengthen the domestic AI ecosystem, supported by a supercomputer cluster built with Nvidia and a National Transfer Office established in Silicon Valley.

AI-focused curricula will be introduced across regional Future Centres to broaden access to advanced training.

A strong emphasis has been placed on nurturing young talent. An annual interschool competition will identify promising AI startup ideas. At the same time, a presidential contest will select one hundred young participants each year for internships in leading technology companies in the US, the UAE and Europe.

November will be marked as ‘AI month for youth’, and the Silk Road AI Forum will become a recurring event.

A central part of the strategy is the ‘five million AI leaders’ project, which aims to train millions of students, along with teachers and public servants, by 2030. The programme will integrate AI education across schools, vocational institutions and universities instead of limiting it to specialist groups.

The government highlighted the country’s growing appeal for technology investment. Nearly two billion dollars have already been secured for AI and digital projects, IT service exports have risen sharply, and startup activity has expanded significantly.

Work has begun on a central green data centre, developed in collaboration with a Saudi partner, as Uzbekistan seeks to strengthen its position in regional digital innovation.

AI detects chronic stress in medical scans

Researchers have developed an AI model capable of detecting chronic stress by examining routine chest CT scans, offering a new way to identify long-term physiological strain that is often difficult to measure.

The system calculates adrenal gland volume, providing clinicians with a clearer understanding of how prolonged stress may affect key hormone-producing organs.

The study examined nearly 3,000 patients and compared their adrenal measurements with cortisol levels, stress questionnaires and markers such as blood pressure and body mass index.

Findings showed that patients with higher reported stress consistently had enlarged adrenal glands and exhibited greater risks of conditions, including heart failure.

Scientists say the new approach provides an objective, scalable tool that uses medical imaging already standard in hospitals, reducing the need for costly or cumbersome testing.

The research team believes the model could help identify a wide range of stress-linked diseases in older adults and ultimately support earlier, more targeted interventions.

Utah governor urges state control over AI rules

Utah’s governor, Spencer Cox, has again argued that states should retain authority over AI policy, warning that centralised national rules might fail to reflect local needs. He said state governments remain closer to communities and, therefore, better placed to respond quickly to emerging risks.

Cox explained that innovation often moves faster than federal intervention, and excessive national control could stifle responsible development. He also emphasised that different states face varied challenges, suggesting that tailored AI rules may be more effective in balancing safety and opportunity.

Debate across the US has intensified as lawmakers confront rapid advances in AI tools, with several states drafting their own frameworks. Cox suggested a cooperative model, where states lead, and federal agencies play a supporting role without overriding regional safeguards.

Analysts say the governor’s comments highlight a growing split between national uniformity and local autonomy in technology governance. Supporters argue that adaptable state systems foster trust, while critics warn that a patchwork approach could complicate compliance for developers.
