Attackers are now agentic. AI agents run reconnaissance, test exploits, and weaponize vulnerabilities at machine speed – collapsing the mean time from CVE disclosure to confirmed exploitation from 2.3 years in 2018 to roughly 10 hours in 2026, with 72.7% of exploited CVEs in 2026 hitting as zero days, up from 16.1% in 2018. Every year, the major breach reports tell the same story.
