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 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.
