AI browsers accused of harvesting sensitive data, according to new study

A new study from researchers in the UK and Italy found that popular AI-powered browsers collect and share sensitive personal data, often in ways that may breach privacy laws.

The team tested ten well-known AI assistants, including ChatGPT, Microsoft’s Copilot, Merlin AI, Sider, and TinaMind, using public websites and private portals like health and banking services.

All but Perplexity AI showed evidence of gathering private details, from medical records to social security numbers, and transmitting them to external servers.

The investigation revealed that some tools continued tracking user activity even during private browsing, sending full web page content, including confidential information, to their systems.

Sometimes, prompts and identifying details, like IP addresses, were shared with analytics platforms, enabling potential cross-site tracking and targeted advertising.

Researchers also found that some assistants profiled users by age, gender, income, and interests, tailoring their responses across multiple sessions.

According to the report, such practices likely violate American health privacy laws and the European Union’s General Data Protection Regulation.

Privacy policies for some AI browsers admit to collecting names, contact information, payment data, and more, and sometimes storing information outside the EU.

The study warns that users cannot be sure how their browsing data is handled once gathered, raising concerns about transparency and accountability in AI-enhanced browsing.

Ukraine pioneers Starlink satellite-to-phone network

Ukraine has completed its first successful field test of Starlink’s direct-to-cell satellite technology, marking a breakthrough for mobile connectivity in Eastern Europe.

The trial, carried out by the country’s largest mobile operator Kyivstar in the Zhytomyr region, saw CEO Oleksandr Komarov and Ukraine’s digital transformation minister Mykhailo Fedorov exchange messages using standard smartphones.

The system connects directly to phones via satellites equipped with advanced cellular modems, functioning like cell towers in space.

The technology is designed to keep communications running when terrestrial networks are damaged or inaccessible.

Telecom companies worldwide are exploring satellite-based solutions to remove coverage gaps instead of relying solely on costly or impractical land-based networks.

Starlink, owned by SpaceX, has already signed direct-to-cell service deals in 10 countries, with Kyivstar set to be the first European operator to adopt it.

A commercial rollout in Ukraine is planned for late 2025, starting with messaging. Broader mobile satellite broadband access is expected in early 2026.

Kyivstar’s parent company, VEON, is also discussing with other providers, such as Amazon’s Project Kuiper, the extension of similar services beyond Ukraine.

GitHub CEO to leave as Microsoft integrates platform into CoreAI amid AI coding race

GitHub CEO Thomas Dohmke has announced his decision to step down later in the year to pursue new entrepreneurial ventures.

Instead of appointing a new CEO, Microsoft will integrate GitHub more closely into its CoreAI division. Since Microsoft acquired GitHub in 2018, the platform has operated chiefly independently, but with this change, leadership will report directly to several Microsoft executives.

Under Dohmke’s leadership since 2021, GitHub’s user base more than doubled to over 150 million developers, supporting over one billion repositories and forks.

The platform has become essential to Microsoft’s AI and developer strategy, especially with growing competition from Google, Replit, and others in the AI coding market.

GitHub recently launched advanced AI tools like Copilot, which suggest code and automate programming tasks, helping developers work more efficiently.

Microsoft’s investment in AI is shaping the future of coding, with GitHub playing a central role by providing direct access to developers worldwide.

Dohmke will remain with Microsoft until the end of the year to assist with the transition, emphasising GitHub’s importance to Microsoft’s broader ambitions in AI and cloud computing.

Musk threatens legal action against Apple over AI App rankings

Elon Musk has announced plans to sue Apple, accusing the company of unfairly favouring OpenAI’s ChatGPT over his xAI app Grok on the App Store.

Musk claims that Apple’s ranking practices make it impossible for any AI app except OpenAI’s to reach the top spot, calling this behaviour an ‘unequivocal antitrust violation’. ChatGPT holds the number one position on Apple’s App Store, while Grok ranks fifth.

Musk expressed frustration on social media, questioning why his X app, which he describes as ‘the number one news app in the world,’ has not received higher placement. He suggested that Apple’s ranking decisions might be politically motivated.

The dispute highlights growing tensions as AI companies compete for prominence on major platforms.

Apple and Musk’s xAI have not responded yet to requests for comment.

The controversy unfolds amid increasing scrutiny of App Store policies and their impact on competition, especially within the fast-evolving AI sector.

Musk and OpenAI CEO Altman clash over Apple and X

After Elon Musk accused Apple of favouring OpenAI’s ChatGPT over other AI applications on the App Store, there was a strong response from OpenAI CEO Sam Altman.

Altman alleged that Musk manipulates the social media platform X for his benefit, targeting competitors and critics. The exchange adds to their history of public disagreements since Musk left OpenAI’s board in 2018.

Musk’s claim centres on Apple’s refusal to list X or Grok (XAI’s AI app) in the App Store’s ‘Must have’ section, despite X being the top news app worldwide and Grok ranking fifth.

Although Musk has not provided evidence for antitrust violations, a recent US court ruling found Apple in contempt for restricting App Store competition. The EU also fined Apple €500 million earlier this year over commercial restrictions on app developers.

OpenAI’s ChatGPT currently leads the App Store’s ‘Top Free Apps’ list for iPhones in the US, while Grok holds the fifth spot. Musk’s accusations highlight ongoing tensions in the AI industry as big tech companies battle for app visibility and market dominance.

The situation emphasises how regulatory scrutiny and legal challenges shape competition within the digital economy.

NASA and Google develop AI doctor for Mars missions

NASA and Google are collaborating on an AI-powered medical assistant designed for long-distance space travel, particularly missions to Mars.

The Crew Medical Officer Digital Assistant (CMO-DA) tool uses Google Cloud’s Vertex AI platform and a mix of open-source large language models to provide autonomous medical advice and diagnostics.

The capability is crucial due to the significant communication delays between Mars and Earth, which can reach up to 223 minutes one way, making real-time medical consultation impossible.

The CMO-DA aims to support astronauts by diagnosing conditions and offering treatment recommendations independently, without Earth-based input. Future versions will incorporate ultrasound imaging and biometric data to enhance diagnostic accuracy.

Tested against common medical issues by a panel that included a doctor-astronaut, the AI demonstrated accuracy rates ranging from 74% to 88% for various ailments.

However, NASA acknowledges challenges such as building trust in AI decisions and limited data on health effects from spaceflight and partial gravity environments.

The project forms part of NASA’s Artemis programme, focusing on Moon exploration and preparing for human missions to Mars, emphasising the importance of autonomous healthcare tools for deep space missions.

Nvidia and AMD to pay 15% share of China AI chip revenue to secure US export licences

Nvidia and Advanced Micro Devices have agreed to hand 15% of their Chinese AI chip sales revenue to the US government in return for export licences.

The arrangement, covering Nvidia’s H20 accelerator and AMD’s MI308 model, is considered unusual and could prove contentious for both companies and Beijing.

The deal reflects Washington’s willingness to link trade concessions to financial payments, but analysts note there is little precedent for such a targeted export levy.

Critics warn the move could undermine the national security rationale for export controls, making it harder to convince allies to adopt similar measures. Beijing, meanwhile, has voiced security concerns over the H20 chip’s performance and alleged vulnerabilities.

Industry observers suggest the payment requirement could discourage further expansion by US chipmakers in China, the world’s largest semiconductor importer, and give local producers an advantage in building domestic capacity.

Chinese firms such as Huawei are already increasing market share amid tighter restrictions on US technology.

The potential sums involved are significant. Before restrictions were imposed, Nvidia had generated over $7 billion in H20 sales to China in a single quarter. In comparison, AMD could earn up to $5 billion annually if full access to the market resumed.

However, uncertainties over demand and regulatory conditions remain.
