Why an SDK is Needed to Protect APIs from Mobile Apps
summary
Backend-only defenses miss tampered mobile clients so APIs remain vulnerable; mobile-originating traffic now exceeds 50% and attackers reverse-engineer apps to automate fraud (Starbucks 2020) and bot amplification (Cahoot 2023). The proposed solution embeds a lightweight SDK that performs app and device attestation, sends measurements to a cloud validator, and returns a cryptographically signed JWT that the backend verifies. This prevents repackaged apps, blocks automated API calls, enables just-in-time API key release, and is compatible with gateways like Cloudflare API Shield.
