Workflow 2: Internal/Assumed-Breach Testing

Step 1: Initial Pod Access
  - Deploy test pod in target namespace
  - Collect service account token
  - Enumerate permissions: kubectl auth can-i --list

Step 2: Internal Reconnaissance
  - List namespaces, pods, services
  - Discover internal services via DNS
  - Check metadata endpoints (cloud IMDS)
  - Identify NetworkPolicy gaps

Step 3: Privilege Escalation
  - Check for wildcard RBAC roles
  - Test service account token from other pods
  - Attempt to create privileged pods
  - Check for vulnerable admission controllers

Step 4: Lateral Movement
  - Access services in other namespaces
  - Extract secrets and configmaps
  - Attempt container escape
  - Access cloud provider metadata

Step 5: Impact Assessment
  - Demonstrate data access (secrets, PVCs)
  - Show cluster-wide compromise path
  - Document attack chain

Workflow 3: Pentest Cleanup

[Testing Complete]
        |
        v
[Remove all pentest pods]
kubectl delete pods -l purpose=pentest -A
        |
        v
[Remove test RBAC resources]
kubectl delete rolebinding pentest-rb
kubectl delete serviceaccount pentest-sa
        |
        v
[Verify cleanup]
kubectl get all -l purpose=pentest -A
        |
        v
[Document findings and hand off report]
