E-commerce & Retail — the risk is business logic, not just code.

The threat, specifically

Retail's costliest incidents rarely trace back to a missing patch — they trace back to logic nobody thought to test: a discount code that stacks when it shouldn't, a cart-total calculation that trusts a client-side price field, a return-authorization flow that skips verification under load. These flaws are invisible to automated scanning because nothing about them is technically malformed — they're just wrong, in a way only a human tester finds by actually trying to defraud the checkout. Outside the app, seasonal campaign microsites and abandoned promotional pages pile up faster than anyone tears them down, and counterfeit storefronts cloned from a real brand run hardest during the exact sale windows when customers are least suspicious.
