The API key enables programmatic scanning.\n\n### Step 2: Upload APK for Static Analysis\n\nUpload the target APK using the MobSF REST API:\n\n```bash\ncurl -F \"file=@target_app.apk\" http://localhost:8000/api/v1/upload \\\n -H \"Authorization: \"\n```\n\nResponse includes the `hash` identifier used for subsequent API calls. MobSF automatically decompiles the APK using JADX, extracts the AndroidManifest.xml, and indexes all resources.\n\n### Step 3: Trigger and Retrieve Static Scan Results\n\nInitiate the static scan and retrieve results:\n\n```bash\n# Trigger scan\ncurl -X POST http://localhost:8000/api/v1/scan \\\n -H \"Authorization: \" \\\n -d \"scan_type=apk&file_name=target_app.apk&hash=\"\n\n# Retrieve JSON report\ncurl -X POST http://localhost:8000/api/v1/report_json \\\n -H \"Authorization: \" \\\n -d \"hash=\"\n```\n\n### Step 4: Analyze Critical Findings\n\nMobSF static analysis covers these categories mapped to OWASP Mobile Top 10 2024:\n\n**Manifest Analysis (M8 - Security Misconfiguration)**:\n- Exported activities, services, receivers, and content providers without permission guards\n- `android:debuggable=\"true\"` left enabled\n- `android:allowBackup=\"true\"` enabling data extraction via ADB\n- Missing `android:networkSecurityConfig` for certificate pinning\n\n**Code Analysis (M1 - Improper Credential Usage)**:\n- Hardcoded API keys, passwords, and tokens in Java/Kotlin source\n- Insecure SharedPreferences usage for storing sensitive data\n- Weak or broken cryptographic implementations (ECB mode, static IV, hardcoded keys)\n\n**Network Security (M5 - Insecure Communication)**:\n- Missing certificate pinning configuration\n- Custom TrustManagers that accept all certificates\n- Cleartext HTTP traffic allowed without exception domains\n\n**Binary Analysis (M7 - Insufficient Binary Protections)**:\n- Missing ProGuard/R8 obfuscation\n- Native library vulnerabilities (stack canaries, NX bit, PIE)\n- Debugger detection absence\n\n### Step 5: Generate and Export Reports\n\nExport findings in multiple formats for stakeholder communication:\n\n```bash\n# PDF report\ncurl -X POST http://localhost:8000/api/v1/download_pdf \\\n -H \"Authorization: \" \\\n -d \"hash=\" -o report.pdf\n\n# JSON for programmatic processing\ncurl -X POST http://localhost:8000/api/v1/report_json \\\n -H \"Authorization: \" \\\n -d \"hash=\" -o report.json\n```\n\n### Step 6: Integrate into CI/CD Pipeline\n\nAdd MobSF scanning as a build gate:\n\n```yaml\n# GitHub Actions example\n- name: MobSF Static Analysis\n run: |\n UPLOAD=$(curl -s -F \"file=@app/build/outputs/apk/release/app-release.apk\" \\\n http://mobsf:8000/api/v1/upload -H \"Authorization: $MOBSF_API_KEY\")\n HASH=$(echo $UPLOAD | jq -r '.hash')\n curl -s -X POST http://mobsf:8000/api/v1/scan \\\n -H \"Authorization: $MOBSF_API_KEY\" \\\n -d \"scan_type=apk&file_name=app-release.apk&hash=$HASH\"\n SCORE=$(curl -s -X POST http://mobsf:8000/api/v1/scorecard \\\n -H \"Authorization: $MOBSF_API_KEY\" -d \"hash=$HASH\" | jq '.security_score')\n if [ \"$SCORE\" -lt 60 ]; then exit 1; fi\n```\n\n## Key Concepts\n\n| Term | Definition |\n|------|-----------|\n| **Static Analysis** | Examination of application code and resources without executing the program; catches structural and pattern-based vulnerabilities |\n| **APK Decompilation** | Process of recovering Java/Kotlin source from compiled Dalvik bytecode using tools like JADX or apktool |\n| **AndroidManifest.xml** | Configuration file declaring app components, permissions, and security attributes; primary target for manifest analysis |\n| **Certificate Pinning** | Technique binding an app to specific server certificates to prevent man-in-the-middle attacks via rogue CAs |\n| **ProGuard/R8** | Code obfuscation and shrinking tools that make reverse engineering more difficult by renaming classes and removing unused code |\n\n## Tools & Systems\n\n- **MobSF**: Automated mobile security analysis framework supporting static and dynamic analysis of Android/iOS apps\n- **JADX**: Dex-to-Java decompiler for recovering readable source code from Android APK files\n- **apktool**: Tool for reverse engineering Android APK files, decoding resources to near-original form\n- **Android Lint**: Google's static analysis tool for Android-specific code quality and security issues\n- **Semgrep**: Pattern-based static analysis engine with mobile-specific rule packs for custom vulnerability detection\n\n## Common Pitfalls\n\n- **Ignoring false positives**: MobSF flags patterns like `password` in variable names even when not storing actual credentials. Triage all HIGH findings manually before reporting.\n- **Missing obfuscated code**: Static analysis accuracy drops significantly against obfuscated apps. Supplement with dynamic analysis for apps using DexGuard or custom packers.\n- **Outdated MobSF rules**: Security rules evolve with Android API levels. Ensure MobSF is updated to match the target app's `targetSdkVersion`.\n- **Skipping native code analysis**: MobSF analyzes Java/Kotlin but has limited coverage of native C/C++ libraries. Use `checksec` and manual review for `.so` files.\n\n## Other files in this skill\n\n- [LICENSE](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-android-app-static-analysis-with-mobsf/LICENSE)\n- [assets/template.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-android-app-static-analysis-with-mobsf/assets/template.md)\n- [references/api-reference.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-android-app-static-analysis-with-mobsf/references/api-reference.md)\n- [references/standards.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-android-app-static-analysis-with-mobsf/references/standards.md)\n- [references/workflows.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-android-app-static-analysis-with-mobsf/references/workflows.md)\n- [scripts/agent.py](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-android-app-static-analysis-with-mobsf/scripts/agent.py)\n- [scripts/process.py](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/performing-android-app-static-analysis-with-mobsf/scripts/process.py)\n\n## assets/template.md (verbatim)\n\n# MobSF Static Analysis Report Template\n\n## Engagement Information\n\n| Field | Value |\n|-------|-------|\n| Application Name | [APP_NAME] |\n| Package Name | [PACKAGE_NAME] |\n| Version | [VERSION] |\n| Target SDK | [TARGET_SDK] |\n| Min SDK | [MIN_SDK] |\n| File Hash (SHA256) | [HASH] |\n| Analysis Date | [DATE] |\n| Analyst | [ANALYST] |\n| MobSF Version | [MOBSF_VERSION] |\n\n## Executive Summary\n\n**Security Score**: [SCORE]/100\n\n**Overall Risk Rating**: [HIGH/MEDIUM/LOW]\n\n[Brief narrative of key findings and overall security posture]\n\n## Findings Summary\n\n| Severity | Count | Categories |\n|----------|-------|------------|\n| Critical | [N] | [Categories] |\n| High | [N] | [Categories] |\n| Medium | [N] | [Categories] |\n| Low | [N] | [Categories] |\n| Info | [N] | [Categories] |\n\n## Manifest Analysis\n\n### Exported Components\n\n| Component Type | Name | Permission Guard | Risk |\n|---------------|------|-------------------|------|\n| Activity | [NAME] | [PERMISSION/None] | [RISK] |\n| Service | [NAME] | [PERMISSION/None] | [RISK] |\n| Receiver | [NAME] | [PERMISSION/None] | [RISK] |\n| Provider | [NAME] | [PERMISSION/None] | [RISK] |\n\n### Permissions Requested\n\n| Permission | Protection Level | Justification | Risk |\n|-----------|-----------------|---------------|------|\n| [PERMISSION] | [dangerous/normal/signature] | [JUSTIFICATION] | [RISK] |\n\n### Manifest Flags\n\n| Flag | Value | Expected | Status |\n|------|-------|----------|--------|\n| android:debuggable | [VALUE] | false | [PASS/FAIL] |\n| android:allowBackup | [VALUE] | false | [PASS/FAIL] |\n| android:usesCleartextTraffic | [VALUE] | false | [PASS/FAIL] |\n\n## Code Analysis Findings\n\n### Finding [N]: [TITLE]\n\n- **Severity**: [CRITICAL/HIGH/MEDIUM/LOW]\n- **CWE**: [CWE-ID]\n- **OWASP Mobile**: [M1-M10]\n- **MASVS**: [MASVS-CATEGORY]\n- **Description**: [DESCRIPTION]\n- **Affected Files**:\n - [FILE_PATH:LINE_NUMBER]\n- **Evidence**: [CODE_SNIPPET]\n- **Recommendation**: [REMEDIATION_STEPS]\n\n## Network Security Analysis\n\n| Check | Result | Details |\n|-------|--------|---------|\n| Certificate Pinning | [Present/Absent] | [DETAILS] |\n| Network Security Config | [Present/Absent] | [DETAILS] |\n| Cleartext Traffic | [Allowed/Blocked] | [DETAILS] |\n| TLS Version | [VERSION] | [DETAILS] |\n\n## Binary Analysis\n\n| Check | Result | Details |\n|-------|--------|---------|\n| Code Obfuscation | [Yes/No] | [DETAILS] |\n| Root Detection | [Present/Absent] | [DETAILS] |\n| Debug Detection | [Present/Absent] | [DETAILS] |\n| Emulator Detection | [Present/Absent] | [DETAILS] |\n| Native Libraries (NX) | [Enabled/Disabled] | [DETAILS] |\n| Native Libraries (PIE) | [Enabled/Disabled] | [DETAILS] |\n| Native Libraries (Stack Canary) | [Present/Absent] | [DETAILS] |\n\n## Recommendations\n\n### Critical (Immediate Action Required)\n\n1.
