Samirbous 4bf05609f3 [New] Kubernetes Admission Webhook Created or Modified (#6078)
* [New] Kubernetes Admission Webhook Created or Modified

Detects creation, modification, or deletion of Kubernetes MutatingWebhookConfigurations or ValidatingWebhookConfigurations
by non-system identities. Admission webhooks intercept every API request matching their rules before persistence, giving an
attacker powerful capabilities: injecting malicious sidecars into every new pod via a mutating webhook, blocking security
tooling deployments via a validating webhook, or silently exfiltrating pod specifications to an external server.  Webhook manipulation is a stealthy persistence and defense evasion technique because the webhook configuration itself looks benign in kubectl output while actively modifying or intercepting all matching Kubernetes API traffic.

rules/

Rules within this folder are organized by solution or platform. The structure is flattened out, because nested file hierarchies are hard to navigate and find what you're looking for. Each directory contains several .toml files, and the primary ATT&CK tactic is included in the file name when it's relevant (i.e. windows/execution_via_compiled_html_file.toml)
