Quick, practical tour of real AWS misconfigurations with live demos and measurable results: uses aws-cli and the IAM Policy Simulator to enumerate privileges, finds three surprising privilege‑escalation chains that allow role chaining into higher‑privilege accounts, demonstrates exploitable S3 bucket ACLs and overly permissive Lambda triggers, and builds a proof‑of‑concept that achieves persistent access and exfiltrates objects. Includes exact CLI commands, Terraform/CloudFormation anti‑patterns to avoid, and remediation steps that were validated on test accounts.
