Mobile Security Code Review

Review native Android and iOS source code for security vulnerabilities by following the full procedure in plays/mobile-code-review.md.

Steps

1. Scope & Context — Language (Java/Kotlin/Swift/Obj-C/Dart), platform, app type, sensitive data, exposure.
2. Platform Detection — Fingerprint Android (AndroidManifest.xml, build.gradle) and/or iOS (Info.plist, *.xcodeproj). If only a cross-platform shell is detected, declare partial coverage.
3. Systematic Review by MASVS Group — For each of the 8 MASVS groups (STORAGE, CRYPTO, AUTH, NETWORK, PLATFORM, CODE, RESILIENCE, PRIVACY) in priority order:
   • Load data/masvs/MASVS-<GROUP>-<N>.md for the control statement and the mastg_tests: list.
   • For each MASTG test ID, load data/mastg/MASTG-TEST-####.md and apply its Static Analysis content (V1) or Steps/Observation/Evaluation (V2) to the source tree.
   • Note V1-fallback tests in findings using the file's status_note.
4. Diff-Specific Analysis (for PRs) — Focus on changed lines; verify pinning, permissions, and KeyStore/Keychain usage are not weakened.
5. Produce Findings — Use templates/finding.md. Sort by severity (CRITICAL > HIGH > MEDIUM > LOW > INFO). Deduplicate cross-group findings (cite the most specific MASVS control in OWASP Ref).

Output

Scope summary (platform, languages), upstream-pointer note for MASTG IDs (https://github.com/OWASP/mastg, https://mas.owasp.org/MASTG/), findings sorted by severity using templates/finding.md (each finding carries an optional MASTG references: bullet listing any non-TEST @MASTG-<KIND>-#### cross-refs cited in the informing tests, grouped by KIND alphabetically, IDs sorted numerically, omitted when empty), positive observations, severity count table, RESILIENCE static-only notice block, PRIVACY runtime-required caveat for findings against PRIVACY-2/PRIVACY-3, dynamic-test follow-up list (collected from data/mastg/ entries with type: [dynamic] that informed findings).
