What it detects

This rule detects DNS queries to ip-api.com which returns geolocation for the host public IP. The Grandoreiro banking trojan queried this service to geolocate victims and select targets, though the service is also used by some legitimate software so context is required.

Detection content is published as a reviewed draft. Tune thresholds and exclusions against your own telemetry before enabling this rule for alerting.
