The Rising Threat: A Surge in Zero-Day Exploits

This report provides a high-level analysis of how APTs and cybercriminals discover, buy, weaponize, and sometimes publicly release zero-day exploits, explains CVE/CVSS scoring and 2022–2024 trend data, outlines the operational and strategic implications of zero-day abuse, and recommends mitigations (patching, defense-in-depth, threat hunting, testing). It is an awareness/maturity-focused piece rather than a technical incident report and contains no specific indicators or active-exploitation case study.
