Indicators

Indicator guidance

Indicators expire. Behaviour usually ages better.

This registry deliberately does not republish volatile IP and domain lists. Pull current indicators from the linked authoritative reporting, match them locally against your own telemetry, and invest your standing detections in the behaviours listed above.
