Horizon3.ai introduces Rapid Response to prioritize and verify vulnerability remediation

Horizon3.ai has introduced Rapid Response, a capability that helps organizations assess exposure to newly disclosed threats, prioritize remediation, and verify that vulnerabilities have been addressed. Security teams are inundated with vulnerability disclosures, threat intelligence feeds, exploit chatter, and vendor advisories, all demanding immediate attention. While tens of thousands of new vulnerabilities are disclosed each year, only a small fraction are actively exploited. Across more than 250,000 NodeZero security assessments, Horizon3.ai has consistently found that exploitability, … More → The post Horizon3.ai introduces Rapid Response to prioritize and verify vulnerability remediation appeared first on Help Net Security.

How NIST fumbled management of the National Vulnerability Database

A US federal watchdog has outlined how the National Institute of Standards and Technology (NIST) failed to effectively manage the growing backlog of unprocessed cybersecurity vulnerabilities in the National Vulnerability Database (NVD). How the NVD crisis unfolded The NVD was established in 2005 and serves as a central repository for cybersecurity vulnerability data. When security researchers or software vendors discover a flaw in a piece of software or hardware, they submit a report through the … More → The post How NIST fumbled management of the National Vulnerability Database appeared first on Help Net Security.

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.
