mobsfscan
mobsfscan is a static analysis tool that scans Android and iOS source code (Java, Kotlin, Swift, Objective-C) for insecure patterns. It integrates MobSF security rules with semgrep and libsast pattern matchers to identify mobile app vulnerabilities before deployment.

What mobsfscan is
Python-based SAST tool that performs pattern matching and semantic analysis on mobile source code, generating findings mapped to CWE, CVSS, OWASP Mobile Top 10, and MSTG. Supports multiple output formats (JSON, SARIF, SonarQube, HTML) and multiprocessing strategies for performance.

Best use cases
Implementation considerations
- Requires Python 3.7+; install via pip. No Docker image or prebuilt binary mentioned; plan environment setup for CI runners.
- Configure rule sets via .mobsf config file; default rules may not align with all organizational standards. Review severity mappings and suppress false positives strategically.
- Multiprocessing mode (default, billiard, thread) impacts memory and CPU; test on typical codebase sizes to avoid CI timeout or resource exhaustion.
- Output formats (JSON, SARIF, SonarQube, HTML) enable downstream integration but require parsing logic; validate output structure before automating.
When to avoid it — and what to weigh
- Need binary or APK/IPA analysis — mobsfscan is source-code only. If you have compiled binaries or must analyze without source, tools like MobSF (the parent framework) or Frida offer complementary approaches.
- Require advanced interactive testing — SAST alone cannot detect runtime vulnerabilities, logic flaws, or data-flow issues across network calls. Combine with dynamic testing (DAST) or penetration testing.
- Expect zero false positives out-of-the-box — Pattern-based and regex-driven rules will have false positives. Plan for tuning and filtering in CI/CD; requires security expertise to maintain signal-to-noise ratio.
- Need real-time IDE integration — mobsfscan is CLI/batch-oriented. IDE plugins or linting integrations are not mentioned in available data; developers run scans separately.
License & commercial use
Licensed under LGPL-3.0 (GNU Lesser General Public License v3.0). LGPL permits proprietary and commercial use with source-code availability requirements.
LGPL-3.0 is a copyleft license. Commercial use is permitted, but if you modify mobsfscan and distribute it, you must disclose source code and license derivative work under LGPL-3.0. Requires legal review if bundling into proprietary products. Standard LGPL commercial deployment (e.g., using unmodified binary in CI/CD) is generally supported but warrants due diligence.

mobsfscan is a scanning tool, not a runtime defense. Pattern-based detection is bounded by rule completeness; zero-day or obfuscated vulnerabilities may be missed. Relies on semgrep and libsast maintenance for engine security. No explicit data sanitization or sandboxing documented for untrusted input scanning. Results should be treated as advisory; human review required before blocking deployments.
Alternatives to consider
MobSF (Mobile Security Framework)
Parent framework supports both source and binary analysis (APK/IPA), dynamic testing, and API fuzzing. More comprehensive but heavier; mobsfscan is the lighter source-only subset.
Semgrep (standalone)
General-purpose SAST engine with extensive rule sets. Requires custom rule authoring for mobile patterns; mobsfscan pre-bundles mobile-specific rules.
Checkmarx / Fortify
Enterprise SAST platforms with mobile support, managed rulesets, and integration ecosystems. Higher cost and operational overhead than open-source alternatives.
