You're tuned in to Tech Beat. Here's what's moving in technology today.
France's cybersecurity agency is pointing the finger at Iran following a sophisticated attack on the country's supermarket cold chain. Hackers reportedly manipulated refrigeration systems across hundreds of stores, causing fridges and freezers to heat up. It's a stark reminder that critical infrastructure vulnerabilities extend well the way into the grocery aisle.
Shifting to something that affects millions of electric vehicle drivers daily — researchers have clarified why fast charging dramatically slows once your battery crosses the eighty percent threshold. The short answer is chemistry and heat. Lithium-ion cells become increasingly resistant to rapid charge acceptance as they fill, and pushing harder risks permanent damage. The slowdown isn't a flaw — it's a deliberate protection mechanism baked into the battery management system.
And finally, a warning for anyone running Planet VPN on Android, which has racked up fifty million downloads. Researchers found the service promotes a Chrome extension called Planet Search that quietly reroutes your web searches through monetized intermediaries before ever reaching your intended results. One security analyst described the behavior plainly — it feels like malware. A free VPN that earns its keep by hijacking your search traffic is a trade-off most users probably didn't knowingly agree to.
Stay skeptical out there. Tech Beat out.
