Dragos acquires Phosphorus to secure extended operational technology

Dragos has acquired Phosphorus, extending the Dragos Platform to protect billions of connected devices embedded across critical infrastructure and other operational networks. Operational environments have outgrown traditional OT boundaries. Power grids, pipelines, manufacturing facilities, and data centers now depend on an increasingly diverse mix of connected devices and digital systems. Traditional and non-traditional assets alike are woven throughout their operational environments. This expanded environment, OT systems and the billions of connected devices that have reshaped … More → The post Dragos acquires Phosphorus to secure extended operational technology appeared first on Help Net Security.

Hackers are exploiting Palo Alto GlobalProtect VPN authentication bypass (CVE-2026-0257)

Authentication bypass vulnerabilities (CVE-2026-0257) in Palo Alto Networks’ firewalls that the company disclosed on May 13 have been targeted in “limited exploit attempts”. “Across multiple customers, Rapid7 observed successful exploitation via authentication probes using forged cookies, but the appliance accepted the cookie without a full VPN session being established in 8 out of 10 impacted [Managed Detection Response] customers.” The good news, though, is that the company hasn’t observed any indication of successful lateral movement … More → The post Hackers are exploiting Palo Alto GlobalProtect VPN authentication bypass (CVE-2026-0257) appeared first on Help Net Security.

The forgotten organ that could predict how long you live

A long-overlooked organ may hold surprising clues to healthy aging and cancer survival. Researchers at Mass General Brigham used AI to analyze CT scans from tens of thousands of adults and found that people with healthier thymuses—a small immune-system organ once thought to become largely irrelevant after childhood—lived longer and had substantially lower risks of heart disease, cancer, and death.

NVIDIA goes open source with a big batch of physical AI agent tools

NVIDIA just dropped a big batch of open-source “physical AI” skills and tools, and they’re designed to make a roboticist’s life a whole lot easier. The idea? Take the messy, complicated work behind robots, self-driving cars, vision AI, and industrial digital twins, and break it into bite-sized tasks that AI agents can actually run themselves. These skills ship as part of the NVIDIA Agent Toolkit, and here’s what makes them handy: they let AI agents … More → The post NVIDIA goes open source with a big batch of physical AI agent tools appeared first on Help Net Security.

DNS-AID lets AI agents find and verify each other through DNS

AI agents run across many platforms, and each one needs a way to locate and confirm the identity of the others it works with. The Linux Foundation’s DNS-AID project gives them that capability through the Domain Name System, the same address lookup system that has directed internet traffic for decades. The project lets AI agents and Model Context Protocol (MCP) servers use DNS as a global, vendor-neutral directory for publishing, discovering, and verifying one another. … More → The post DNS-AID lets AI agents find and verify each other through DNS appeared first on Help Net Security.

Asimily turns device risk into automated network policy

Asimily has launched Segmentation Orchestration, enabling connected-device risk intelligence to flow directly into enforceable network policy without manual translation. No other platform combines full asset visibility, vulnerability prioritization, and segmentation orchestration in a single system. “AI has exploded the volume and sophistication of network attacks against connected devices, and security teams are discovering that visibility tools and manual policies cannot keep pace,” said Shankar Somasundaram, CEO, Asimily. “Attackers are exploiting the space between what organizations … More → The post Asimily turns device risk into automated network policy appeared first on Help Net Security.

This strange crystal acts like metal and glass at the same time

A remarkable crystal called molybdenum oxychloride could help make futuristic technologies like smart contact lenses and ultrathin AR glasses a reality. Scientists have created the first detailed experimental map of its optical properties, revealing the strongest light-bending effect ever measured in a natural material. The crystal can act either like a reflective metal or transparent glass, allowing it to manipulate light with extraordinary efficiency while being thousands of times thinner than a human hair.

Data discovery gaps that catch enterprises off guard

In this interview with Help Net Security, Avani Desai, CEO at Schellman, talks about the gap between what organizations think they know about their data and what discovery scans turn up. She shares stories of shadow data in abandoned cloud storage, post-merger surprises where duplicated datasets slowed integration, and why synthetic data is overmarketed while confidential computing stays underappreciated. Desai also explains why smaller companies often beat large enterprises on compliance, and the one question … More → The post Data discovery gaps that catch enterprises off guard appeared first on Help Net Security.
