First-Ever Attack Leveraging Kubernetes RBAC to Backdoor Clusters

We have recently discovered the first-ever evidence that attackers are exploiting Kubernetes (K8s) Role-Based Access Control (RBAC) in the wild to create backdoors. The attackers also deployed DaemonSets to take over and hijack resources of the K8s clusters they attack. Our research suggests that this campaign is actively targeting at least 60 clusters in the …
