The “Create files below dev” event in a Kubernetes cluster indicates that a process running within a container has attempted to create files in the “/dev” directory.
This event could be a potential security concern as the “/dev” directory contains device files that provide direct access to hardware devices. Creating files in this directory could be an attempt to gain unauthorized access or manipulate system resources.
To investigate this event, you can use the following kubectl command to list the pods running in the cluster and check their logs for any suspicious activity:
kubectl get pods --all-namespaces
Use the Kubernetes API to create a Python script that generates a Kubernetes manifest file for creating a Pod with a volume mount to the “dev” directory.
