Monitor CVEs Linked to Ransomware Campaigns

Ransomware reporting often mixes campaigns, malware families, initial-access techniques, and speculative product lists. The CISA KEV Scraper provides a narrower source: catalog entries CISA explicitly marks as known to be used in ransomware campaigns.

Configure an evidence-based feed

Use the dedicated filter rather than searching descriptions for the word ransomware:

{"query":"","ransomwareOnly":true,"sort":"newest","maxResults":250}

The output retains CISA's vendor, product, CVE, description, required action, due date, notes, and catalog version. It does not infer campaign names, attacker identity, likelihood, or exposure. That boundary is useful because downstream teams can add internal asset and threat context without confusing it with the source record.

Join each CVE to the asset inventory using vendor, product, CPE, package, or scanner evidence already maintained by the organization. Human review is still necessary when product naming differs. Prioritize internet-facing and high-impact systems, but keep the original CISA fields visible in the ticket so analysts can verify the decision.

For monitoring, persist the previous complete set of CVE IDs. Alert only on IDs not seen in the prior baseline or on material field changes such as required action, due date, ransomware status, or notes. Do not replace the baseline after an incomplete upstream request; otherwise a recovery run can falsely announce the whole catalog as new.

Unknown ransomware status is not negative evidence. Keep a separate general KEV feed for actively exploited CVEs that lack a known ransomware association. The ransomware view is a focused operational lens, not a substitute for vulnerability management, endpoint detection, backups, segmentation, or incident response planning.
