CVE-2026-20929, a vulnerability with a CVSS of 7.5 that was patched in the January 2026 Patch Tuesday update, enables attackers to exploit Kerberos authentication relay through DNS CNAME record abuse. This blog focuses on detecting one particularly impactful attack vector: relaying authentication to Active Directory Certificate Services (AD CS) to enroll certificates for user accounts, as detailed in recent research.

The era of human-speed defense is over. With eCrime breakout times collapsing to as fast as 27 seconds and attacks from AI-powered adversaries increasing 89% year-over-year, the traditional SOC has reached a breaking point. Manual processes, fragmented tools, and rule-based playbooks were built for a different era. Today, if your defense depends on human reaction time, you’re not just behind — you’re at risk.

Interest in cloud-native application protection platforms (CNAPPs) has exploded over the recent years, partly due to their ability to reduce alert noise by translating siloed misconfigurations into correlated, theoretical attack paths and exposures. While many organizations have adopted these solutions in pursuit of outcomes like zero critical issues, cloud breaches continue to rise.

In modern organizations, sensitive data lives everywhere and is constantly moving. It is created, accessed, transformed, and shared across endpoints, browsers, SaaS applications, cloud services, GenAI tools, and agentic workflows. CrowdStrike is introducing CrowdStrike Falcon Data Security to protect data across constantly evolving business environments.

As organizations race to adopt new AI tools, deploy AI agents, and build AI-powered software, they create new attack surfaces that traditional security controls were never designed to protect. A key example is the prompt and agentic interaction layer, which faces novel threats like indirect prompt injection and agentic tool chain attacks.

CrowdStrike is expanding CrowdStrike Falcon Next-Gen SIEM to support third-party endpoint detection and response (EDR) solutions — beginning with Microsoft Defender — with no Falcon sensor required. This evolution will enable organizations to modernize their SOC without replacing existing endpoint agents. Adversaries are moving faster than ever, exploiting cross-domain gaps across endpoint, identity, network, and cloud.

While investigating a spike in script execution detections across several CrowdStrike Falcon platform customers, CrowdStrike’s Engineering team traced the activity to a compromised GitHub Action named aquasecurity/trivy-action. This popular open-source vulnerability scanner is frequently used in CI/CD pipelines.
