This rule detects potential impersonation attempts via the "kubectl" command in Linux environments. It identifies process events where "kubectl" is executed with arguments that suggest an attempt to impersonate another user or group, such as using "--kubeconfig", "--token", "--as", or "--as-group". This could indicate an adversary trying to gain unauthorized access or escalate privileges within a Kubernetes cluster. If this rule is triggered, in conjunction with rules related to secret access or kubeconfig file discovery, it may indicate a potential impersonation attempt.
