CVE-2026-20127 — Cisco SD-WAN Zero-Day Tracker

Tracking entry for CVE-2026-20127, a critical Cisco Catalyst SD-WAN authentication bypass vulnerability actively exploited and requiring immediate mitigation.

Exploitation Velocity in Modern Campaigns — A Practical Defense Model for Enterprises

This SECMONS research brief analyzes how exploitation velocity turns vulnerabilities into enterprise-scale incidents, using verified historical cases (Log4Shell, CitrixBleed, MOVEit, SolarWinds) to propose a practical prioritization and containment model.

CVE-2026-25108 — FileZen Zero-Day Tracker

Tracking entry for CVE-2026-25108, an actively exploited FileZen OS command injection vulnerability enabling remote attackers to execute arbitrary commands on exposed systems.

Zero-Day Tracker — Active & Recently Disclosed Zero-Day Vulnerabilities | SECMONS

The SECMONS Zero-Day Tracker monitors publicly disclosed zero-day vulnerabilities and confirmed in-the-wild exploitation events. This tracker provides structured, verified intelligence for defenders.

Drive-By Compromise — When Visiting a Website Is Enough

A drive-by compromise is an attack technique where a victim’s system is compromised simply by visiting a malicious or compromised website. This SECMONS glossary entry explains how drive-by attacks work, how they relate to browser vulnerabilities and zero-days, and what defenders should monitor.

Exploit Kit — Automated Browser Exploitation Infrastructure

An exploit kit is a toolkit hosted on attacker-controlled infrastructure that automatically scans visiting systems for vulnerabilities and delivers exploits without user interaction beyond visiting a page. This SECMONS glossary entry explains how exploit kits work, their role in drive-by compromise campaigns, and why patch velocity is critical.

Exploited in the Wild — What It Means, How It’s Confirmed, and Why It Changes Risk

“Exploited in the wild” indicates that a vulnerability is actively being used in real-world attacks outside controlled research environments. This SECMONS glossary entry explains what qualifies as in-the-wild exploitation, how vendors confirm it, and how defenders should respond operationally.

Zero-Day Vulnerability — What It Means, How It’s Used, and Why It’s High Risk

A zero-day vulnerability is a software flaw that is exploited before a patch is available or before the vendor is aware of it. This SECMONS glossary entry explains what qualifies as a zero-day, how it differs from n-day vulnerabilities, how zero-days are weaponized, and how defenders should respond.

Zero-Day Exploitation Patterns Observed in 2026

Analysis of how zero-day vulnerabilities are discovered, weaponized, and exploited in 2026, including patterns in targeting, speed, and attack execution.
