MVP social engineering begins the moment your product steps into the world. The first build is not just code — it is a signal. Every choice in design, onboarding, and messaging is an opening that people will read, test, and exploit. If you ignore that, you give away control.
Social engineering at the MVP stage happens fast. It is not limited to malicious actors; it includes any user behavior shaped by your public interface. Fake signups, free-trial abuse, gaming referral systems, or probing APIs for hidden functionality all come from the same truth: people respond to incentives and exposed pathways.
To defend against it, start with threat modeling before launch. Map every feature to a possible misuse case. If your MVP offers login, think about credential stuffing and shared accounts. If it has a payment system, expect sandbox manipulation and coupon abuse. A single overlooked workflow can become a backdoor to your data or resources.
