Certified Ethical Hacker (CEH) Practice Question

The described attack forces the cloud provider to spin up and run a large number of expensive Lambda invocations. Although the function itself does not crash, the excessive, attacker-driven usage directly translates into higher pay-per-use charges for the victim organization. This is a textbook example of the "denial of wallet" threat that is common in serverless environments, where the goal is to exhaust the target's budget rather than its technical resources. The other options do not focus on cost exhaustion: a classic denial-of-service seeks to degrade availability; event data injection manipulates function logic; and privilege escalation abuses roles to gain more access.
