PulseAPK is a professional-grade GUI for Android reverse engineering and security analysis, built with WPF and .NET 8. It combines the raw power of apktool with advanced static analysis capabilities, wrapped in a high-performance, cyberpunk-inspired interface. PulseAPK streamlines the entire workflow from decompilation to analysis, rebuilding, and signing.

You can also perform the Smali code analysis. Just drag and drop the Smali folder into the Analysis tab.

If you want to build (and sign, if necessary) the Smali folder - use the "Build APK" section.

Key Features

• 🛡️ Static Security Analysis: Automatically scan Smali code for vulnerabilities, including root detection, emulator checks, hardcoded credentials, and insecure SQL/HTTP usage.
• ⚙️ Dynamic Rule Engine: Fully customizable analysis rules via smali_analysis_rules.json. Modify detection patterns on the fly without restarting the application. Uses caching for optimal performance.
• 🚀 Modern UI/UX: A responsive, dark-themed interface designed for efficiency, featuring drag-and-drop support and real-time console feedback.
• 📦 Complete Workflow: Decompile, Analyze, Edit, Recompile, and Sign APKs in one unified environment.
• ⚡ Safe & Robust: Includes intelligent validation and crash prevention mechanisms to protect your workspace and data.
• 🔧 Fully Configurable: Manage tool paths (Java, Apktool), workspace settings, and analysis parameters with ease.

Advanced Capabilities

Security Analysis

PulseAPK includes a built-in static analyzer that scans decompiled code for common security indicators:

• Root Detection: Identifies checks for Magisk, SuperSU, and common root binaries.
• Emulator Detection: Finds checks for QEMU, Genymotion, and specific system properties.
• Sensitive Data: Scans for hardcoded API keys, tokens, and basic auth headers.
• Insecure Networking: Flags HTTP usage and potential data leakage points.

Rules are defined in smali_analysis_rules.json and can be customized to your specific needs.

APK Management

• Decompilation: Effortlessly decode resources and sources with configurable options.
• Recompilation: Rebuild your modified projects into valid APKs.
• Signing: Integrated keystore management for signing rebuilt APKs, ensuring they are ready for device installation.

Prerequisites

1. Java Runtime Environment (JRE): Required for apktool. Ensure java is in your system PATH.
2. Apktool: Download apktool.jar from ibotpeaches.github.io.
3. Ubersign (Uber APK Signer): Required for signing rebuilt APKs. Download the latest uber-apk-signer.jar from the GitHub releases.
4. .NET 8.0 Runtime: Required to run PulseAPK on Windows.

Quick Start Guide

1. Download and Build

   dotnet build
   dotnet run
   

2. Setup

   • Open Settings.
   • Link your apktool.jar path.
   • PulseAPK will automatically detect your Java installation based on environment variables.

3. Analyze an APK

   • Decompile your target APK using the Decompile tab.
   • Switch to the Analysis tab.
   • Select your decompiled project folder.
   • Click Analyze Smali to generate a security report.

4. Modify & Rebuild

   • Edit files in your project folder.
   • Use the Build tab to recompile into a new APK.
   • Use the Sign tab to sign the output APK.

Technical Architecture

PulseAPK utilizes a clean MVVM (Model-View-ViewModel) architecture:

• Core: .NET 8.0, WPF.
• Analysis: Custom Regex-based static analysis engine with hot-reloadable rules.
• Services: dedicated services for Apktool interaction, file system monitoring, and settings management.
