| name | performing-android-app-static-analysis-with-mobsf |
| description | Performs automated static analysis of Android applications using Mobile Security Framework (MobSF) to identify hardcoded secrets, insecure permissions, vulnerable components, weak cryptography, and code-level security flaws without executing the application. Use when assessing Android APK/AAB files for security vulnerabilities before deployment, during penetration testing, or as part of CI/CD security gates. Activates for requests involving Android static analysis, MobSF scanning, APK security assessment, or mobile application code review.

Performing Android App Static Analysis with MobSF
When to Use
Use this skill when:
- Conducting security assessment of Android APK or AAB files before production release
- Integrating automated mobile security scanning into CI/CD pipelines
- Performing initial triage of Android applications during penetration testing engagements
- Reviewing third-party Android applications for supply chain security risks
Do not use this skill as a replacement for manual code review or dynamic analysis -- MobSF static analysis catches pattern-based vulnerabilities but misses runtime logic flaws.
Most Often Missed & How to Confirm
- Obfuscated code drops detection — MobSF accuracy falls against DexGuard/packers. Confirm gaps by checking the decompiled output is readable; if not, supplement with dynamic Frida analysis before trusting a "clean" result.
- Native
.so libraries — a Java/Kotlin-only scan misses C/C++ flaws. Confirm by running checksec on the libs and manually reviewing JNI entry points.
exported default by SDK level — a component without android:exported is exported below API 31. Confirm the effective state against targetSdkVersion, not just the manifest line.- Hardcoded secret false positives — confirm a flagged key is live by using it against the real endpoint before reporting.
- Network security config — confirm cleartext/trust-anchor settings in
res/xml/network_security_config.xml rather than assuming defaults.
- Runtime-only logic — static analysis misses logic flaws; confirm by pairing with the dynamic-analysis skill on a device.
Prerequisites
- MobSF v4.x installed via Docker (
docker pull opensecurity/mobile-security-framework-mobsf) or local setup
- Target Android APK, AAB, or source code ZIP
- Python 3.10+ for MobSF REST API integration
- JADX decompiler (bundled with MobSF) for Java/Kotlin source recovery
- Network access to MobSF web interface (default: http://localhost:8000)
Workflow
Step 1: Deploy MobSF and Obtain API Key
Launch MobSF using Docker for isolated, reproducible scanning:
docker run -it --rm -p 8000:8000 opensecurity/mobile-security-framework-mobsf:latest
