The fake app (Trojan) is disguised as a banking app (FakeBank) targeting Iranian users (.ir) and can steal two-factor verification codes (Spy). In short, it's not something anyone wants on their phone. Both Stripe and Simplify offer a variety of APIs, tools, code samples, and connectors to various payment-related apps. I like the way Simplify arranges its code samples, as you can see in this screenshot.
Are your customers installing dangerous apps that undermine layers of security and separate them (and you) from your hard-earned cash?
