Potential Sidecar Injection Into Running Deployment
Detects attempts to inject a sidecar container into a running deployment. A sidecar container is an additional container within a pod, that resides alongside the main container. One way to add containers to running resources like Deployments/DeamonSets/StatefulSets, is via a "kubectl patch" operation. By injecting a new container within a legitimate pod, an attacker can run their code and hide their activity, instead of running their own separated pod in the cluster.
