WHOIS / Registration

Registration data planned

Registrar, creation/expiry dates and domain status via RDAP. Rolling out gradually — bulk WHOIS is rate-limited, so we resolve on a prioritized cadence.

Subdomains

Subdomain enumeration pending

Every subdomain ever issued a TLS cert under this apex — extracted from Certificate Transparency logs, our own scan observations and body references.

Tech Stack

Tech detection pending

Wappalyzer-rules detect CMS, frameworks, analytics, JS libs and server-side languages on this domain.

TLS Certificates

Certificate observations pending

TLS certs naming this domain in subject or SANs will appear here as our scan-layer catches them.

IPs Citing This Domain

Hosts whose HTML body references this domain. Strong signal for origin/mirror/embed discovery.

Origin / IP-Leak

USP

When a hostname is served behind a CDN (e.g. Cloudflare), the origin server can sometimes be identified by matching its TLS cert against the protected hostname. Findings shown here are heuristic candidates, not guarantees.

No origin-IP leaks detected (yet)

Either this domain doesn't sit behind a CDN, or we haven't seen a TLS cert from a non-CDN IP matching this hostname. Run a fullscan to refresh the cert→IP cross-reference.

Threat Intelligence

Domain threat-intel pending

Matches in URLhaus, OpenPhish, PhishTank, malware feeds, and Spamhaus DBL.

History

Domain timeline pending

Passive-DNS history accumulates as our forward-DNS crawler observes A/AAAA/MX/NS/TXT records over time.
