In the Netherlands there's an official government agency that allows a simple mail or report: https://www.ncsc.nl/en/report-an-incident-to-ncsc-nl

I presume more countries have this, not sure about the US though (CISA maybe? CERT/CC?). CERT is the overarching org that manages local agencies like this Dutch NCSC. Though I am not sure if and how easy it is, globally, to report incidents.
