I have been using Shodan, “the world’s first search engine for Internet-connected devices”, since a long time. Recently I switched my free account to a membership account. A membership account allows you to do API queries with additional query filters (for example restricting search results to specific countries).
In this post I describe the results of querying the Shodan API for ICS (or related) devices in Belgium. These results are entirely based on what is … Read more.

But there’s always room for improvement. If you submit a feature request, MISP can be extended with your request. However changing the core is not always desirable.
