A Kubernetes event is a Kubernetes object that logs state changes and failures of the resources in the cluster. Example events are a container creation, an image pull, or a pod scheduling on a node. Kubernetes events can be very useful for identifying changes that occur in the cluster. Therefore, attackers may want to delete these events (e.g., by using: “kubectl delete events–all”) in an attempt to avoid detection of their activity in the cluster.

List who has delete/deletecollection RBAC permissions on events.
You should follow the least privilege principle. Minimize the number of subjects who can delete Kubernetes events. Avoid using these subjects in the daily operations.
