What it detects

This rule identifies Kubernetes API activity where the resource type is events and the verb is delete. Deleting events can be used to reduce visibility and hinder incident investigation by removing recorded event data. It relies on Kubernetes audit logs capturing the request verb and the targeted resource reference (events).
