VulnCheck finds three hidden backdoors in ZBT-made routers sold under many brand names

Security firm VulnCheck discovered three separate backdoor-like implants embedded in firmware made by Shenzhen Zhibotong Electronics (ZBT), whose hardware is resold globally under numerous brand names. The most severe, dubbed ENDLESSDOORS, disguises itself as a Linux kernel process, phones home to a hard-coded command server without authentication or encryption, and grants attackers root-level control over the router. VulnCheck confirmed the flaw is real by hijacking a test router's command channel themselves, and identified it across 20 ZBT-based router models.

Vandals Destroying Flock License Plate Cameras Win Public Sympathy, Even in Court

Across the US, people who disable or destroy Flock automatic license plate reader towers are being celebrated online rather than condemned, with social media posts backing vandals over police who install the surveillance cameras. In one case an Ohio grand jury declined to indict a man caught on video destroying a Flock camera, and public backlash has pushed some Wisconsin towns to drop their Flock contracts after a neighboring city ended its own.

HP settles patent lawsuit with Huawei over essential Wi-Fi technology

HP Inc. has entered a patent licensing agreement with Huawei to resolve a legal dispute over Wi-Fi-related intellectual property that Huawei holds. The settlement lets HP continue using the patented Wi-Fi technology in its products without incorporating any Huawei components or hardware. HP clarified the deal is purely a licensing settlement, not a partnership or endorsement of Huawei products, which remain effectively banned from the US market.

Study Ties Daily Diet Soda-Level Sweetener Intake to Faster Cognitive Decline

An eight-year study published in Neurology found that adults consuming roughly the amount of artificial sweetener contained in one daily diet soda experienced memory and mental sharpness decline 62 percent faster than those consuming far smaller amounts. The research tracked participants over time to compare cognitive changes based on sweetener consumption levels.

Early Leak of Nvidia's DLSS 5 Reportedly Degrades Visuals and Halves Frame Rates

An early, unofficial build of Nvidia's upcoming DLSS 5 upscaling technology has surfaced through mods, and initial testing suggests it produces worse image quality than expected while cutting gaming performance roughly in half. Testers say the AI-driven rendering ignores the original artistic style of games, producing an over-processed look rather than a faithful enhancement.

Modders port leaked DLSS 5 Neural Rendering to RTX 4000 GPUs

A day after DLSS 5's nvngx_dlssnr.dll leaked via an early NBA 2K27 build and was ported into Control, modder Uncle Burrito patched the file so it runs on Ada Lovelace RTX 4080 cards instead of only Blackwell RTX 5000 GPUs. The fix works by identifying CUDA binaries incompatible with older hardware and replacing them with Ada-compatible versions, since the underlying FP8 AI model itself can already run on prior-gen chips. Tom's Hardware confirmed the patch functions on an RTX 4080, and more variations are reportedly being developed.

Etymology deep dive traces 'weird' back to Old English fate word 'wyrd'

A language essay from The Dead Language Society examines how the everyday word 'weird' descends from Old English 'wyrd,' a term meaning fate or destiny that appears in poems like Beowulf and The Wanderer. The piece traces the shift from wyrd's grim, inexorable sense of 'that which happens' to its modern casual usage describing odd smells or strange coworkers.

Engineer builds battery-free NFC business card with animated LEDs and onboard MCU

A hobbyist designed a PCB business card that uses an NFC chip's energy-harvesting capability to power 21 LEDs and an ATtiny412 microcontroller, all without a battery. Tapping the card against a phone triggers an LED animation, drawing power solely from the phone's NFC field via chips like the NXP NTAG I2C Plus or STMicro ST25DV-KC that can route excess harvested voltage to external components. The creator built the project in about three months as a way to learn KiCad, and has published the full design files publicly.
