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.

Warning: You should NOT use red-kube commands on a Kubernetes cluster that you don't own!

Q&A

Why choosing kubectl and not using the kubernetes api in python?

When performing red team assessments and adversary emulations, the quick manipulations and tweaks for the tools used in the arsenal are critical.

The ability to run such assessments and combine the k8s attack techniques based on kubectl and powerful Linux commands reduces the time and effort significantly.
