OSINT Domain & Infrastructure Recon

Passive DNS enumeration, certificate transparency log inspection, and mail server security audit.

Perform passive Open Source Intelligence (OSINT) reconnaissance against target domains without sending intrusive probe packets. Inspect DNS records (A, AAAA, MX, TXT, NS, CAA), query public Certificate Transparency (CT) logs to discover unindexed subdomains, verify SPF/DMARC email authentication health, and export structured attack surface intelligence dossiers.

Features

• Passive DNS record mapper (A, MX, TXT, CAA)
• Certificate Transparency log subdomain discovery
• SPF & DMARC email spoofing audit
• One-click intelligence dossier JSON export
