Add Experiments for Persistence Tactic #30
Description
The persistence tactic consists of techniques that are used by attackers to keep access to the cluster in case their initial foothold is lost.
Backdoor container
Attackers run their malicious code in a container in the cluster. By using the Kubernetes controllers such as DaemonSets or Deployments, attackers can ensure that a constant number of containers run in one, or all, the nodes in the cluster.
Writable hostPath mount
hostPath volume mounts a directory or a file from the host to the container. Attackers who have permissions to create a new container in the cluster may create one with a writable hostPath volume and gain persistence on the underlying host. For example, the latter can be achieved by creating a cron job on the host.
Kubernetes CronJob
Kubernetes Job is a controller that creates one or more pods and ensures that a specified number of them successfully terminate. Kubernetes Job can be used to run containers that perform finite tasks for batch jobs. Kubernetes CronJob is used to schedule Jobs. Attackers may use Kubernetes CronJob for scheduling execution of malicious code that would run as a container in the cluster.
