This rule identifies the creation of Virtual Private Cloud (VPC) routes in Google Cloud Platform (GCP). In GCP, VPC routes determine how network traffic flows from VM instances to certain destinations, both internal and external to the VPC. Malicious actors may create or alter these routes to control or eavesdrop on traffic flows, disrupting operations or stealing sensitive information. The detection is based on monitoring specific audit events linked to VPC route creation, which allows for early detection of unauthorized modifications to network configurations. The rule uses the KQL query language to capture events where a route is inserted, indicating possible nefarious activities in the cloud environment.
