## Core Insights

A young domain is a valuable risk signal, especially when observed beside brand impersonation or a captured phishing page. However, registration age alone can never establish malicious intent.

1. **Age at Detection:** PhishDestroy measures age as the difference between the domain registration date (creation_date) and the first detection date (detected_at), rather than today's date. This preserves the historical context of the campaign.
2. **Domain vs. Subdomain:** Domain age applies to the registrable domain, not necessarily to hosted subdomains beneath it. Hostnames on shared hosting platforms can be brand-new even if the parent domain is years old.
3. **Common Errors:** Security teams must avoid misinterpreting "last changed" as "registration," treating missing WHOIS/RDAP as age zero, or assuming old domains are safe (missing compromised legitimate hosts).

## Recommended Defender Workflow

1. Resolve the registrable domain and separate it from subdomain/paths.
2. Query RDAP for the original registration timestamp (creation_date).
3. Pair registration timing with captured page content (form fields, brand assets).
4. Analyze infrastructure details (DNS, IP reputation, TLS certificates, reused page hashes).
