Traditional deception tools promised high signal but failed at scale. This page explores how NodeZero® Active Directory Tripwires transform deception into a practical, enterprise-ready detection strategy—using real attacker behavior to deliver early, high-fidelity alerts where identity attacks matter most.

CVE-2026-21858, the so-called “Ni8mare” n8n RCE, drew significant attention—but real-world impact appears limited. Horizon3 breaks down the technical prerequisites, observed exposure, and why most organizations are unlikely to be affected.

Sangoma FreePBX Authentication Bypass and Remote Code Execution Vulnerabilities

We dive into a new set of FreePBX issues beyond CVE-2025-57819: an authentication bypass in webserver mode (CVE-2025-66039), multiple SQL injections (CVE-2025-61675), and an arbitrary file upload bug leading to remote code execution (CVE-2025-61678). Together, they allow authenticated or unauthenticated attackers to achieve code execution on vulnerable FreePBX instances using risky auth settings. This write-up…

Patch Tuesday is a known event, but attackers are moving faster than ever. For a leading U.S. manufacturer, shifting from simple patching to continuous validation became the key to proving their fixes worked, turning uncertainty into confidence.
