Ranks domain registrars by live compromised domains relative to registered domains attributed to each registrar (NetAPI WHOIS zone data).
Daily signals from public threat-intelligence sources are matched to registrars via RDAP/WHOIS and compared to registered domain counts.

This report is based on NetAPI datasets and daily signals collected from public and private threat-intelligence sources.
A domain may appear if it has been observed in phishing, malware distribution, spam, botnet activity, or other potentially abusive behavior within the last 24 hours (same window as our current compromised domain lists).
The presence of a domain in this report does not necessarily indicate malicious intent by the domain owner, registrar, registry, or hosting provider. Many domains are compromised without the owner's knowledge.
Overall abuse rate uses all live compromised domains and all active domains across NetAPI zones. Per-registrar rows use that registrar's registered domain count (from WHOIS/RDAP data).
The table lists registrars with at least 1,000 registered domains. We count only domain names we can match to a registrar (not subdomains or hosts we cannot attribute).
Statistics are updated daily and may change as new data becomes available.
