# mobsfscan
**mobsfscan** 是一个静态分析工具，能够在 Android 和 iOS 源代码中查找不安全的代码模式。支持 Java、Kotlin、Android XML、Swift 和 Objective C 代码。mobsfscan 使用 [MobSF](https://github.com/MobSF/Mobile-Security-Framework-MobSF) 静态分析规则，并由 [semgrep](https://github.com/returntocorp/semgrep) 和 [libsast](https://github.com/ajinabraham/libsast) 模式匹配器提供支持。

## 配置 mobsfscan
源代码目录根目录下的 `.mobsf` 文件允许你配置 mobsfscan。你也可以使用 `--config` 参数指定自定义的 `.mobsf` 文件。
```
---
- ignore-filenames:
- skip.java
ignore-paths:
- __MACOSX
- skip_dir
ignore-rules:
- android_kotlin_logging
- android_safetynet_api
- android_prevent_screenshot
- android_detect_tapjacking
- android_certificate_pinning
- android_root_detection
- android_certificate_transparency
severity-filter:
- WARNING
- ERROR
```
## 抑制检测结果
你可以通过在触发检测结果的源代码行添加注释 `// mobsf-ignore: rule_id1, rule_id2` 来抑制检测结果。
示例：
```
String password = "strong password"; // mobsf-ignore: hardcoded_password
```
