The Current State of Zero-Day Vulnerability Trends in Late 2025 As we navigate late 2025 and push into 2026, the landscape around zero-day vulnerabilities has evolved far beyond the realm of nation-state APTs. While state-sponsored actors remain a significant driver, the commercial exploit market has matured into a sophisticated, multi-billion-dollar industry. We’re seeing a significant democratisation of these capabilities, with even mid-tier criminal syndicates now able to acquire vulnerabilities and exploits that, just a few years ago, would have been considered highly exclusive. The attack surface has continued its relentless expansion, driven by widespread adoption of cloud-native architectures, IoT proliferation, and increased interconnectedness across supply chains. The convergence of these factors means the dwell time for many zero-days, once discovered by a threat actor, is shri
