Shodan is a search engine that scans IP addresses for connected devices like routers, webcams, servers, and industrial control systems, identifying open ports, unsecured devices, and services running on systems. It helps identify potential entry points and vulnerabilities in these devices.
The purpose of filters in Shodan is to refine and narrow down search results to find specific types of devices, services, vulnerabilities, etc, on the internet.
The filter ssl.cert.subject.cn:becode.org in Shodan is used to search for devices whose SSL/TLS certificates contain a specific Common Name (CN) in the subject field.
ssl.cert.subject.cn:shinyhat.org
