Kubestroyer aims to exploit Kubernetes clusters misconfigurations and be the swiss army knife of your Kubernetes pentests


About The Project

Kubestroyer is a Golang exploitation tool that aims to take advantage of Kubernetes clusters misconfigurations.

The tool is scanning known Kubernetes ports that can be exposed as well as exploiting them.

Getting Started

To get a local copy up and running, follow these simple example steps.
