INFRASTRUCTURE ACTOR REGISTRY

INFRA Registry

Tracked hosting operators whose infrastructure is used, at material scale, for malicious activity. Each entry carries an INFRA-NN designation and the structural signatures needed to confirm new sightings in registry data.

Reading a designation

Suffixes stack in this order, with U always last.

-R Reseller
Leases IP space or sponsorship to third parties.
-T Abuse-tolerant
Sustained malicious activity by customers with no enforcement response.
-C Concealment-forward
Rotating shell registrants, brokered sponsorships or country-attribution mismatches.
-S State-adjacent
Documented credentialled ties to state entities. Not evidence of state tasking.
-U Under investigation
Structural map incomplete; attribution set still pending.

A designation covers the hosting operation, not any tenant's conduct. It is a research tracking label, not a sanctions designation or an accusation of state tasking.
