Episode 6 — Understand instance metadata APIs and why attackers love them

This episode explains instance metadata services as a high-value target in cloud environments, because they can expose identity tokens, configuration data, and privileged context to workloads that should not have it. You’ll define what metadata APIs are, why they exist, and how applications and agents legitimately use them for bootstrapping and discovery. Then we pivot to attacker thinking: how server-side request forgery (SSRF), misrouted proxy traffic, or compromised workloads can query metadata endpoints to harvest credentials or discover paths to escalate. We’ll tie these mechanics to exam-relevant concepts like workload identity, temporary credentials, and trust boundaries, and walk through a scenario where a seemingly “minor” web flaw turns into account-wide access after metadata tokens are retrieved.
