Introduction:

In the vast ocean of the internet, there exists a tool that serves as a key to unlocking the secrets of connected devices. Shodan, often referred to as the "search engine for hackers," is not a tool for malicious intent but a powerful resource for understanding the digital footprint we leave behind. 

1. Basic Search:

5. Filter by Country:
• You can filter results by country using country:US.
6. Using Operators:
• Combine filters with logical operators like AND, OR, and NOT for more complex queries.
7. Banner Grabbing:
• Get detailed information about a specific service using ssl:certificate.
8. Vulnerability Search:
• Identify potential vulnerabilities using vuln:search_term.
9. Identifying Industrial Control Systems (ICS):
• Use tag:ics to find devices associated with industrial control systems.
10. Explore IoT Devices:

• Search for specific IoT devices using category:iot.
