Scientists twist crystal layers and reshape matter from within

Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up. Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a laboratory curiosity into a practical platform for next-generation electronics.

CISA lays out new guidance for using open-source software

The US Cybersecurity and Infrastructure Security Agency (CISA) has published the Open Source Software: Security Principles and Practices guide, which provides federal agencies with recommendations for managing the security of open source software, contributing to OSS projects, and evaluating open source AI systems. Using open source software Federal agencies can benefit from open source software because its source code can be independently reviewed, reducing reliance on vendor claims. It can reduce dependence on a single … More → The post CISA lays out new guidance for using open-source software appeared first on Help Net Security.

KindaRails2Shell threatens Ruby on Rails apps (CVE-2026-66066)

A critical security vulnerability (CVE-2026-66066) in Ruby on Rails (aka Rails), one of the most widely used frameworks for building websites and web apps, may allow attackers to read sensitive files off a server and, in some cases, take full control of it. Nicknamed “KindaRails2Shell” by the researchers who found it, the flaw lets an attacker sneak a booby-trapped file past a website’s image-upload feature and use it to pry open the server’s secrets.

Qodana 2026.2 adds post-quantum crypto checks for JVM code

Qodana 2026.2 shipped with new security inspections, published benchmark results, post-quantum cryptography checks, and coverage reporting that no longer has to be pointed at the reports. The security work sits in the .NET linter and runs by default. Qodana tracks untrusted data across files in C#, JavaScript, and TypeScript, which turns up SQL injection, command injection, cross-site scripting, and path traversal in places a single-location rule misses. Findings show up in the IDE and in … More → The post Qodana 2026.2 adds post-quantum crypto checks for JVM code appeared first on Help Net Security.

OpenAI reveals how criminals used ChatGPT to run scams

OpenAI banned a coordinated network of ChatGPT accounts that likely originated in Cambodia’s Preah Sihanouk province, a region reports have linked to online scam compounds and human trafficking operations. The network used the company’s models to create and manage fake online personas, generate and translate messages sent to scam targets, produce promotional content for fraudulent schemes, and support daily operations. Earlier this year, a lead from WhatsApp prompted OpenAI to investigate and disrupt a Cambodia-based … More → The post OpenAI reveals how criminals used ChatGPT to run scams appeared first on Help Net Security.

Elastic Defend now covers 800+ vulnerable drivers, with automated troubleshooting and ARM support

Attackers reaching for kernel access on a Windows machine bring a driver Microsoft already trusts. It is signed, it loads, and it carries a known flaw. That flaw gives them enough room to tamper with memory or disable the security software watching the host. Once an attacker holds that level of access, the tools on the machine stop reliably protecting it. Ransomware crews run the technique as a step before they deploy a payload, a … More → The post Elastic Defend now covers 800+ vulnerable drivers, with automated troubleshooting and ARM support appeared first on Help Net Security.
