This rule detects the execution of Kubernetes CronJobs within Google Cloud's Kubernetes environment (GKE). Kubernetes CronJobs are used for scheduling the execution of pods to perform specific tasks at designated times. However, adversaries may exploit Kubernetes CronJobs to schedule and execute malicious code within the cluster, potentially leading to unauthorized access or disruption of services. The detection rule operates by monitoring GCP audit logs for specific method names related to Job and CronJob actions. If a CronJob or Job method is invoked, this could indicate scheduled activity that might need further investigation, especially in a security context where such jobs may be used for malicious purposes.
