What it detects

This rule detects curl or wget accessing the mounted Kubernetes service account token path, a credential theft technique observed in current threats to Kubernetes environments. The service account token grants API access with the pod's privileges, so reading it with a download tool indicates an attacker harvesting cluster credentials from a compromised container.
