LLM Denial of Wallet Does Not Need to Overwhelm Anything
LLM denial of wallet borrows a term that predates generative AI by a decade: a 2021 Register piece on a "theoretical Denial-of-Wallet attack" described the same economic logic OWASP now applies to LLM APIs as Unbounded Consumption. Pay-per-token pricing means an attacker does not need to overwhelm anything. Requests that are simply expensive, long context windows, recursive agent loops, complex reasoning chains, drain the budget at normal traffic volume.
