Attack Surface
Complete domain ecosystem mapping
Key Concepts
DNS Analysis
Analyze DNS records to understand domain infrastructure and services.
- • A record analysis for IP mapping
- • MX record enumeration for mail servers
- • CNAME record mapping for aliases
- • TXT record analysis for additional info
Certificate Analysis
Extract intelligence from SSL certificates and certificate transparency logs.
- • Subject Alternative Names discovery
- • Certificate chain analysis
- • Expiry date monitoring
- • Issuer information analysis
Subdomain Discovery
Find hidden subdomains and infrastructure components.
- • Certificate transparency logs
- • Brute force enumeration
- • DNS zone transfer attempts
- • Search engine discovery
Infrastructure Mapping
Map complete domain infrastructure and attack surface.
- • Service enumeration
- • Port scanning integration
- • Technology stack identification
- • Attack vector mapping
Legal and Ethical Considerations
Legal Compliance
- • Only query public DNS records
- • Respect rate limits and terms of service
- • Obtain proper authorization for testing
- • Comply with local cybersecurity laws
Ethical Guidelines
- • Use intelligence for legitimate purposes
- • Respect infrastructure and services
- • Avoid disruptive scanning techniques
- • Maintain professional conduct
