'Reverse engineers malicious Android APK files using JADX decompiler.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Reverse Engineering Android Malware with JADX

## When to Use

- A suspicious Android APK has been reported as malicious or flagged by mobile threat detection
- Analyzing Android banking trojans, spyware, SMS stealers, or adware samples
- Determining what data an app collects, where it sends it, and what permissions it abuses
- Extracting C2 server addresses, encryption keys, and configuration data from Android malware
- Understanding overlay attack mechanisms used by banking trojans

**Do not use** for analyzing obfuscated native (.so) libraries within APKs; use Ghidra or IDA for native ARM binary analysis.

## Prerequisites

- JADX 1.5+ installed (download from https://github.com/skylot/jadx/releases)
- Android SDK with `aapt2` and `adb` tools for APK inspection
- apktool for full APK disassembly including smali code and resources
- Python 3.8+ with `androguard` library for automated APK analysis
- Frida for dynamic instrumentation (optional, for runtime analysis)
- Isolated Android emulator (Genymotion or Android Studio AVD) without Google services

## Workflow

### Step 1: Extract APK Metadata and Permissions

Examine the APK structure and AndroidManifest.xml:

```bash
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add adriannoes/awesome-agentic-ai/reverse-engineering-android-malware-with-jadx@sha256:91eb61b48b0823b5

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
