SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This skill solves the need for rapid, passive infrastructure intelligence without relying on external API keys or complex third-party services.

Core Features & Use Cases

Passive Reconnaissance: Perform subdomain discovery, SSL inspection, and WHOIS lookups using only standard Python libraries.
Bulk Analysis: Run multiple intelligence checks across a list of domains in parallel to audit large infrastructure sets.
Use Case: Quickly verify the registration status, DNS records, and SSL certificate health of a list of domains to assess their security posture or availability.

Quick Start

Use the domain-intel skill to perform a full DNS and SSL check on example.com.

FAQPage Schema

How do I perform passive domain reconnaissance without external API keys?▼

Passive domain reconnaissance without external API keys is achieved by leveraging standard Python libraries to query public certificate logs and perform direct network queries for subdomain discovery, SSL inspection, and WHOIS lookups.

What is the best way to check SSL certificate health and DNS records for multiple domains?▼

The best way to check SSL certificate health and DNS records for multiple domains is by running bulk intelligence checks in parallel, allowing you to quickly audit large infrastructure sets without relying on third-party services.

Can I use Python to discover subdomains using certificate transparency logs?▼

Yes, you can use Python to discover subdomains by querying public certificate transparency logs directly, operating without any external API dependencies to gather infrastructure intelligence passively.

Do I need to install third-party libraries to run WHOIS lookups and DNS resolution?▼

No, you do not need to install third-party libraries to run WHOIS lookups and DNS resolution; the task operates entirely using standard Python libraries for direct network queries.

When do I need passive OSINT infrastructure intelligence for security auditing?▼

You need passive OSINT infrastructure intelligence for security auditing when you must verify domain registration status, assess DNS records, and inspect SSL certificates without alerting targets or requiring external API keys.
