subdomain-takeover-detection

Detect and analyze domain/subdomain takeover vulnerabilities. Use this skill whenever the user mentions subdomain takeover, domain takeover, dangling DNS records, CNAME vulnerabilities, orphaned cloud resources, or wants to audit DNS records for security issues. This skill helps identify when a subdomain points to a third-party service that's no longer claimed, allowing attackers to take control.
