Shodan Search Engine Tutorial - Access Routers,Servers,Webcams + Install CLI
How to Use Shodan
Shodan is a type of search engine that allows users to search for Internet-connected devices and explicit website information such as the type of software running on a particular system and local anonymous FTP servers. Shodan can be used much in the same way as Google, but indexes information based on banner content, which is meta-data that servers send back to hosting clients. For the best results, Shodan searches should be executed using a series of filters in a string format.
Navigate to the Shodan website at .
Click on “Register” at the top right corner of Shodan’s home page.
Enter a username, email address, and password, then click on “Submit.”Shodan will send you a verification email.
Open the verification email and click on the URL provided to activate your Shodan account.The Shodan login screen will open in a new window of your browser.
Log into Shodan using your username and password.
Enter search terms into the search field at the top of your Shodan session using a string format.For example, if you want to locate all Internet-connected devices in the United States that are currently using default passwords, enter “default password country: US.”
Click on “Search” to execute your search.The Web page will refresh and display a list of all devices, or banners that match your search terms.
Narrow your search using a series of filters in your string command.Common search filters include the following:
- City: Users can limit search results to devices located by city. For example, “city:sacramento.”
- Country: Users can restrict search results to devices by country using the two-digit country code. For example, “country:US.”
- Hostname: Users can limit search results to devices by the value in their hostname. For example, “hostname:facebook.com.”
- Operating system: Users can search for devices based on operating system. For example, “microsoft os:windows.”
Click on any listing to learn more about that particular system.Most listings will display explicit information about systems that include their IP address, latitude and longitude, SSH and HTTP settings, and server name.
How to check my own devices/network at home? Same question as the one above.
Could Shodan be used to see if I have vulnerable devices at my house? If so, what do I type in?
- Narrow down your search using additional filters by purchasing add-ons from Shodan. Click on “Buy” at the top right corner of your current Shodan session to purchase and gain access to additional filters for search.
- If you are in charge of system administration for your business or company, use Shodan to ensure that your system is set up in a manner that can’t be easily hacked by malicious third parties. For example, search for your system using string terms that include “default password” to verify that your system is not using default passwords, which could compromise your system’s security.
