Cloud providers provide instance metadata service for retrieving information about the virtual machine, such as network configuration, disks, and SSH public keys. This service is accessible to the VMs via a non-routable IP address that can be accessed from within the VM only. Attackers who gain access to a container, may query the metadata API service for getting information about the underlying node. For example, in Azure, the following request would retrieve all the metadata information of an instance: http:///metadata/instance?api-version=2019-06-01\n\n
Check which nodes have access to instance metadata services. The check is for AWS, GCP and Azure.
Disable metadata services for pods in cloud provider settings.
