World’s smallest QR code, smaller than bacteria, could store data for centuries

Scientists have created a microscopic QR code so tiny it can only be seen with an electron microscope—smaller than most bacteria and now officially a world record. But this isn’t just about size; it’s about durability. By engraving data into ultra-stable ceramic materials, the team has opened the door to storing information that could last for centuries or even millennia without needing power or maintenance.

Scientists just found a way to store massive data using light in 3 dimensions

A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and polarization, rather than just on a surface. An AI model then reconstructs the data from light patterns, simplifying the process. This could pave the way for faster, denser, and more efficient data storage systems.

Week in review: NIST updates DNS security guidance, compromised LiteLLM PyPI packages

Here’s an overview of some of last week’s most interesting news, articles, interviews and videos: NIST updates its DNS security guidance for the first time in over a decade DNS infrastructure underpins nearly every network connection an organization makes, yet security configurations for it have gone largely unrevised at the federal guidance level for more than twelve years. NIST published SP 800-81r3, the Secure Domain Name System Deployment Guide, superseding a version that dates to … More → The post Week in review: NIST updates DNS security guidance, compromised LiteLLM PyPI packages appeared first on Help Net Security.

Attackers are exploiting RCE vulnerability in BIG-IP APM systems (CVE-2025-53521)

A critical unauthenticated remote code execution vulnerability (CVE-2025-53521) in F5’s BIG-IP Access Policy Manager (APM) solution is under active exploitation, the US Cybersecurity and Infrastructure Security Agency warned on Friday. CISA added the flaw to its Known Exploited Vulnerabilities catalog after F5 updated the related security advisory, The advisory was initially published on October 15, 2025, when F5 confirmed a data breach that resulted in a “highly sophisticated nation-state threat actor” accessing – among other … More → The post Attackers are exploiting RCE vulnerability in BIG-IP APM systems (CVE-2025-53521) appeared first on Help Net Security.
