Newly Registered Domains (NRD)
Most malicious domains are registered from a few days to only a few seconds before becoming active, making those domains a very valuable subset of domains to analyze when looking for future malicious activity.
Traditional approaches usually have a 24-hour blindspot and do not cover ccTLDs. We use a combination of passive DNS, zone files, Certificate Transparency logs and WHOIS/RDAP to detect most newly registered domains near instantly.
