hunt-subdomain

To scan a domain for subdomain takeover vulnerabilities, run the 'hunt-subdomain example.com' command. The Skill enumerates target subdomains, fingerprints third-party providers, checks for misconfigured CNAMEs and unregistered namespaces, and requires manual verification for potential impact analysis.

Subdomain takeover occurs when a DNS CNAME points to an unregistered or deprovisioned third-party service namespace. The Skill identifies these misconfigured DNS records during security audits, allowing attackers to claim the endpoint and host unauthorized content.

Yes, subfinder and amass are required dependencies for the subdomain enumeration phase. Additionally, nuclei and subjack are used for provider fingerprinting and vulnerability analysis to detect misconfigured CNAMEs and unregistered namespaces effectively.

Yes, you can automate subdomain takeover detection for cybersecurity audits by running the provided scripts against target domains. The Skill performs DNS resolution and provider fingerprinting automatically, though manual verification is required to confirm the vulnerability and assess impact.

Automated subdomain takeover detection requires manual verification to confirm vulnerabilities, as DNS resolution and provider fingerprinting may yield false positives. Limitations include dynamic DNS changes and the need to validate unregistered namespaces before reporting a definitive takeover risk.

The best way to find unregistered namespaces during a penetration test is using subdomain enumeration combined with provider fingerprinting. This Skill leverages subfinder, amass, and subjack to detect misconfigured CNAMEs pointing to unclaimed third-party resources, yielding actionable takeover targets.
