You shipped the app to millions.
Has anyone attacked it on purpose?
Mobile apps carry secrets, talk to sensitive backends, and run on devices you do not control. SpartanX tests your iOS and Android builds the way an attacker would, then chains what it finds into the APIs and identity behind them.
The app is the easy half. The backend behind it is the prize
A mobile app ships to every attacker's device at once. They can pull it apart at leisure: hardcoded secrets, insecure storage, weak certificate handling, and the assumptions the app makes about a backend it cannot see protecting itself.
Most mobile testing stops at the client and never follows the path into the APIs and data behind it. That is exactly where the real damage is. The question is not whether the binary has issues. It is what those issues unlock once they are chained to everything behind the app.
Test the app, then follow it home
Attack the build
The platform tests each iOS and Android build for insecure storage, hardcoded secrets, weak transport security, and client-side logic an attacker can abuse.
Reach the backend
The APIs the app depends on are tested as first-class assets, so a weakness in the client becomes a proven path into the services behind it.
Chain across surfaces
Findings are chained with identity, cloud, and web exposures, because a real mobile compromise rarely stops at the phone.
Prove and prioritize
Every confirmed weakness ships with a reproducible proof of concept and a score weighted by real business impact.
Ship mobile you have actually attacked
Client and backend in one test
Proof, not a checklist
Two builds, counted honestly
What a decompiled build hands an attacker, and how far the APIs behind your app would let them go.
