Shodan is a search engine for Internet-connected devices.

Based on specified subnet or list of subnets, data fetched from Shodan include: hostname, ports open to the world, vulnerabilities, address information (country, region, city), ISP and more.

The Shodan adapter connection requires the following values:

  1. Shodan Domain – Should be kept as 'api.shodan.io'.
  2. CIDR - Specify a subnet to be used for fetching data from Shodan. If you want Shodan to scan multiple subnets, use the CIDR CSV File option to upload a CSV file with a list of subnets.
  3. API Key – Specify the API key you have defined. For details, see 'Generating Shodan API Key' section below
  4. HTTPS Proxy (optional) - You can configure a proxy specifically to the adapter instead of directly approaching the domain.
  5. Upload a CSV file or specify a query search:
    • Upload a CSV file
      • CIDR CSV File Name (optional) - If you upload several CIDR CSV files (in different Shodan adapter servers), you can specify a logical name for that file. The name will be displayed in the Shodan adapter server list, enabling you to easily distinguish between different Shodan adapter servers.
      • CIDR CSV File - Upload a CSV file with a list of subnets to be used for fetching data from Shodan.
        CSV file structure:
        • "CIDR" column - Mandatory. Each row in the CSV should be populated with its subnet in the "X.Y.Z.N/P" format.
        • DNSNAME column - optional. Each row in the CSV should be poulated with the server name, if known.
    • Specify a query search
      • Query Search - Specify a search query using Shodan's search query syntax. This field will tell the adapter to execute the query you have specified to find devices information.
  6. Choose Instance - If you are using multi-nodes, choose the Axonius node that is integrated with the adapter. By default, the 'Master' Axonius node (instance) is used. For details, see Connecting Additional Axonius Nodes
