How we count
Every figure on this page is a direct count of entries in CISA’s Known Exploited Vulnerabilities catalog attributed by CISA to SmarterTools (KEV field vendorProject), refreshed daily. “Ransomware-linked” counts entries CISA marks as known to be used in ransomware campaigns; the remainder are “unknown” to CISA, not confirmed ransomware-free. A KEV listing means the vulnerability has been observed exploited in the wild. Snapshot as of 2026-09-02.
