Passive Reconnaissance

Gathering information about a target without interacting directly with it.

Understanding:


Passive reconnaissance is the collection of publicly available data about a target without directly interacting with the system.

Common Applications and Use Cases:


  • OSINT Gathering – Using Shodan, WHOIS, and DNS queries.

  • Social Engineering Attacks – Collecting personal details for phishing.

Best Practices and Security Considerations:

  • Limit Publicly Available Information – Reduce attack surface exposure.

  • Use Threat Intelligence Tools – Detect reconnaissance activity.
