You Should Know: Shodan Search Queries & Practical Commands
1. Basic Shodan Search Queries
Shodan allows filtering using specific search operators:
– `net:` Search by IP range (e.g., net:192.168.1.0/24)
– `port:` Filter by open ports (e.g., port:22,80,443)
– `country:` Search by country (e.g., country:US)
– `os:` Find devices by OS (e.g., os:"Windows Server")
– `product:` Search for specific software (e.g., product:"Apache httpd")
Example:
shodan search 'product:"Apache httpd" country:US' --limit 10
2. Using Shodan CLI for Reconnaissance
Install Shodan CLI and configure your API key:
pip install shodan shodan init YOUR_API_KEY
Search for vulnerable IoT devices:
shodan search 'webcamxp port:80'
Scan a specific IP for vulnerabilities:
shodan host 8.8.8.8
3. Automating Shodan Scans with Python
Use the `shodan` Python library to automate searches:
import shodan
api = shodan.Shodan('YOUR_API_KEY')
results = api.search('nginx')
for result in results['matches']:
print(f"IP: {result['ip_str']}, Port: {result['port']}")
4. Finding Exposed Databases
Discover open MongoDB instances:
shodan search 'product:MongoDB "MongoDB Server Information"'
Find exposed Redis servers:
shodan search 'product:Redis port:6379'
5. Discovering Industrial Control Systems (ICS)
Search for exposed SCADA systems:
shodan search 'SCADA port:502'
Find PLC devices:
shodan search 'Siemens SIMATIC'
6. Hunting Vulnerable Web Servers
Find Apache servers with directory listing enabled:
shodan search 'http.title:"Index of /"'
Locate misconfigured Nginx servers:
shodan search 'http.component:nginx "Server: nginx"'
7. Detecting Vulnerable VPNs
Search for OpenVPN servers:
shodan search 'OpenVPN'
Find exposed Citrix Gateways:
shodan search 'http.html:"Citrix Gateway"'
What Undercode Say
Shodan is an essential tool for cybersecurity professionals, bug bounty hunters, and penetration testers. Mastering Shodan Dorking helps identify exposed systems before attackers do. Always use Shodan ethically and responsibly—unauthorized scanning can be illegal.
Expected Output:
- Discover exposed databases, IoT devices, and industrial systems.
- Automate reconnaissance with Python and CLI tools.
- Strengthen security by identifying misconfigurations before hackers do.
