The Current State of Zero-Day Vulnerability Trends in Late 2025 Diving into the zero-day exploit market in late 2025, from my vantage point at AGMP Partners, it's clear the landscape has shifted significantly since earlier in the decade. The prevalence of sophisticated supply chain attacks, coupled with the increasing commoditization of exploit development frameworks, means that attributing zero-day usage confidently has become a monumental task. We're seeing a bifurcation: on one hand, nation-state actors continue to hoard and refine high-value, multi-stage zero-days targeting critical infrastructure and classified data; on the other, financially motivated groups are increasingly leveraging N-day vulnerabilities, but with a rapid exploitation window that mimics zero-day impact. The line blurs when a disclosed vulnerability is exploited within hours of public disclosure, often before pat
