Transparency is one of the foundational features of blockchains, but it enabled value extraction by controlling the order and inclusion of transactions within a block, known as MEV, or maximal extractable value. This problem is common on most blockchains and is rooted in the public nature of mempools, a ledger that stores pending transactions data. This information allowed block producers and other actors to benefit from frontrunning transactions.

Caroline Wilson Palow, legal director of the campaign group Privacy International, said the new order might be "just as big a threat to worldwide security and privacy" as the old one. She said: "If Apple breaks end-to-end encryption for the UK, it breaks it for everyone. The resulting vulnerability can be exploited by hostile states, criminals, and other bad actors the world over."

Meta will soon use your conversations with its AI assistant to personalize the ads you see on its platforms. The change, which goes into effect on December 16th, means you'll also start seeing suggested posts, reels, and Facebook groups related to your AI text and voice chats, too. So if you ask Meta AI about hiking, Meta might learn that you're interested in the topic and show recommendations for hiking groups on Facebook, posts from friends about local trails, or ads for hiking boots.

If true, this new order is not 'less worse' than the first. That's because, as we have been saying all along, Apple cannot undermine end-to-end encryption of iCloud services only for the UK when those services are used worldwide. If Apple breaks end-to-end encryption for the UK, it breaks it for everyone. The resulting vulnerability can be exploited by hostile states, criminals and other bad actors the world over.

The UK has agreed to drop its mandate for Apple to provide a 'back door' that would have enabled access to the protected encrypted data of American citizens and encroached on our civil liberties,

On Tuesday, NordVPN subscribers received an email noting that the community's response to the news prompted the VPN provider to change its mind and keep Meshnet running.

"Your passion made us take a hard look at our decision. So here's the update: We heard you. Meshnet is not going anywhere."

Dutch mobile security company ThreatFabric said it discovered the campaign in August 2025 after users in Australia reported scammers managing Facebook groups promoting "active senior trips." Some of the other territories targeted by the threat actors include Singapore, Malaysia, Canada, South Africa, and the U.K. The campaigns, it added, specifically focused on elderly people looking for social activities, trips, in-person meetings, and similar events. These Facebook groups have been found to share artificial intelligence (AI)-generated content, claiming to organize various activities for seniors.

The cap integrates -powered vision technology capable of detecting when a smartphone camera is directed toward it. Once identified, a built-in mechanism deploys a cover that drops over the wearer's face, concealing their identity and preventing unwanted appearance in social media content.

For years, "know your customer" checks have become commonplace on the internet, often by way of sharing a copy of your government-issued ID and a selfie to confirm that it's really you, to access a website or app, or to purchase certain goods. Nowadays, age verification laws taking effect across the U.S., the United Kingdom, Australia, and beyond are also giving rise to an entire industry of ID-checking companies charged with granting you access to the "adult" web.

Governments are increasingly relying on data-intensive systems, both to wage wars and to administer public services. These systems, increasingly provided by the same firms using similar tools, will come to affect our day-to-day lives whether we are in war zones or town squares. This is the era of Militarisation of Tech. The technologies that our governments rely on to deliver services and pursue their objectives are becoming increasingly data-intensive and militarised, which threatens our privacy, dignity, and autonomy.

I started using Google Drive, Gmail, and the whole suite of tools back when they were still invite-only. Back then, the cloud was an unknown entity, and many of us had no idea that it would become the backbone of both business and personal use. According to , the public cloud market alone will break the $1 trillion mark by 2026. indicates that 67% of senior executives say that their organization has accelerated its plans for cloud adoption. That's a lot of people using cloud services, and it's only going to continue to grow.
