Key Vulnerability Trends in 2026

Trinity Cyber's H1 2026 telemetry reports prevention of over 2.3 million exploitation attempts and identifies three key trends: attackers increasingly use disposable bulletproof and residential infrastructure to evade reputation-based blocking; botnets continue to industrialize mass exploitation against unpatched systems; and AI speeds exploit development while producing inaccurate/noisy public PoCs. The report advises defenders to favor prevention-first controls that inspect behavior and content, validate exploit intelligence carefully, and not rely solely on reputation or patching windows.
