The Path Less Traveled: Abusing Kubernetes Defaults - Duffie Cooley, VMware & Ian Coldwater, Heroku
Abstract
While the industry and the community are starting to pay attention to Kubernetes security, there are many attack paths that aren’t well-documented, and are rarely discussed. This lack of information can make your clusters vulnerable.In this live demonstration-filled talk, we are going to provide an overview of the Kubernetes control plane before using sigs.k8s.io/kind to show some of the attack surface exposed by a default configuration of Kubernetes. There will be multiple exploits involving various moving parts, including cluster takeovers and host escapes. We’ll show you mitigations, and then show you how to get around those.The audience will walk away from this talk with a better understanding of Kubernetes’ default attack surface, how it can be exploited, and how to keep their clusters safer.
