This is another series of posts I’ll be making that cover basic use-cases and building blocks for Censys Search--this one is called “How can I...”

We’ll start out with “How can I find hosts in a specific country running a specific software?“ Here’s an example query that returns hosts in Russia detected running gSOAP:

location.country=Russia and services.software.product: gSOAP

This query uses the location.country field to set a geographic boundary and the services.software.product field to identify the software in focus.

Another potential starting point for this would be to start with simply the location.country=Russia query and then run a report on those results that uses services.software.product as the breakdown field. This will provide you with a window into the types of software products that have been detected on hosts in Russia, allowing you to identify software of interest and perform follow-up queries.
