## What it is
AppShark is a static taint analysis platform written in Kotlin that scans Android APKs for security vulnerabilities and compliance issues. It runs as a JVM-based CLI tool driven by JSON5 config files and custom analysis rules, producing JSON results.

## Use cases
- scan an android apk for security vulnerabilities
- find taint flows from sources to sinks in android apps
- detect compliance problems in android apps
- detect zip slip path traversal vulnerabilities
- write custom static analysis rules for android

## When to choose
- you need static taint analysis of Android APKs without running the app
- you want customizable JSON-based vulnerability detection rules
- you need to audit Android apps for privacy or compliance violations

## When to avoid
- you need dynamic analysis or runtime behavior of the app
- you are analyzing non-Android JVM or native code
- you cannot use JDK 11, the only supported runtime

## Facets
