That “Safe” Guest Wi-Fi Network May Not Be Isolating Anyone
Wi-Fi has become the invisible wiring of modern life. Billions of devices rely on it every day, from phones and laptops to smart TVs and industrial systems. That scale has always made wireless security a high-stakes problem. Now new research shows that a fundamental protection built into nearly every router can be quietly bypassed, allowing attackers on the same network to intercept and tamper with traffic that was supposed to be isolated and protected.

For decades, modern encryption has rested on a simple assumption. Some math problems take so long to solve that no practical computer can crack them in a useful timeframe. That assumption built online banking, secure email, VPN tunnels, software signing, and almost every digital transaction that powers business and government today.
A new attack called Pixnapping can steal sensitive data from Android devices, without needing a single permission. The exploit targets visual data on-screen, including two-factor authentication codes, private messages, and location histories. It works by quietly measuring how long it takes to render specific pixels. If that sounds like science fiction, it’s not. Researchers have already tested it on Pixel and Samsung devices with unsettling results. 
After nearly a decade, Microsoft is finally closing the book on Windows 10. As of today, free support and regular security patches have officially ended. But despite the headlines, your computer is not about to implode. If you plan wisely, or even just use decent security software, you can keep running Windows 10 safely for a quite a bit longer.

The concern was clear: anyone with those credentials could impersonate Cloudflare’s resolver, decrypt user traffic, or redirect queries to malicious sites.
