# Mobile App Security

Mobile apps ship on a release cycle, not a continuous deploy pipeline — which means a vulnerability that reaches the app store can sit exposed on user devices for weeks before a fix goes out. Testing before release isn't optional; it's the only point where you can actually stop a mobile vulnerability before it reaches production.

## Where Mobile Apps Actually Fail

Mobile app security testing looks different from web testing because the attacker has something they never get with a web app: a copy of your binary, running on a device they fully control. Alastor InfoSec's Mobile App Security engagements combine static and dynamic analysis to reflect that:

- **Insecure local storage** — credentials, tokens, or sensitive data stored unencrypted in shared preferences, keychains, or local databases.
- **Weak backend API authentication** — the API behind your app tested independently, since a mobile client is just another (fully attacker-controlled) way to call it.
- **Reverse-engineering resistance** — how easily your app can be decompiled, and whether hardcoded secrets, API keys, or business logic are exposed in the process.
- **Insecure communication** — certificate pinning gaps, weak TLS configuration, and man-in-the-middle exposure.
- **Platform-specific misconfiguration** — exported Android components, insecure deep links, jailbreak/root detection bypass, and iOS entitlement issues.

## Static and Dynamic, Together

Static analysis alone misses runtime behavior; dynamic analysis alone misses issues baked into the binary. We run both, on real devices and emulators, against release-candidate builds — so findings reflect what actually ships, not a theoretical code review.

Because most mobile apps are really a thin client in front of a web API, Mobile App Security engagements are typically scoped alongside [Web App Security](/features/web-app-security) testing for the backend, giving you one coherent picture of the whole product instead of two disconnected reports.

## Who Needs This

Any consumer or enterprise mobile app handling authentication, payments, health data, or personal information needs testing before every major release — not just once at launch. This matters even more under India's DPDP Act (DPDPA), where a mobile app leaking personal data through insecure local storage is a compliance incident, not just a bug ticket.
