Reviews mobile security across Flutter, native Android, native iOS, React Native and Kotlin Multiplatform using OWASP MASVS. Covers credential storage, secrets, transport, deep links, WebViews, logging and platform implementations of shared KMP contracts. Use for security audits, auth/token handling, pentest findings or release hardening.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Mobile Security

Organized by the OWASP MASVS categories. Apply the general checks below, then the reference for the detected stack. In cross-platform apps, also apply the Android and iOS references to the native folders.

## 1. Pick the reference

| Project | Read |
|---|---|
| Flutter | [references/flutter.md](references/flutter.md) |
| Native Android (Kotlin/Java), or `android/` in any app | [references/android.md](references/android.md) |
| Native iOS (Swift/Objective-C), or `ios/` in any app | [references/ios.md](references/ios.md) |
| React Native or Expo | [references/react-native.md](references/react-native.md) |
| Kotlin Multiplatform shared code and platform implementations | [references/kotlin-multiplatform.md](references/kotlin-multiplatform.md) |
| OAuth 2.0 / OIDC login, PKCE, tokens and biometric gating, on any stack | [references/auth.md](references/auth.md) |

Firebase-specific protection (security rules, App Check) is covered by `mobile-firebase`.

How to install

The exact contents, by fingerprint
mdr add wrsilva/reis-mobile/mobile-security@sha256:0a71b4f8bf05caf5

The line at the top of this page pins the label git:20261013.5b43e60, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
