Red-Kube : Red Team K8S Adversary Emulation Based On Kubectl

Red-Kube is a collection of kubectl commands written to evaluate the security posture of Kubernetes clusters from the attacker’s perspective.

The commands are either passive for data collection and information disclosure or active for performing real actions that affect the cluster.

The commands are mapped to MITRE ATT&CK Tactics to help get a sense of where we have most of our gaps and prioritize our findings.

The current version is wrapped with a python orchestration module to run several commands in one run based on different scenarios or tactics.

Please use with care as some commands are active and actively deploy new containers or change the role-based access control configuration.
