ReArk

English | 简体中文

ReArk is a professional reverse engineering tool for HarmonyOS NEXT applications. It analyzes .hap, .app, and .abc files, with support for disassembly, decompilation, string analysis, cross-references, signature inspection, re-signing, package browsing, repackaging, application metadata, Agent-assisted analysis, device interaction, and evidence trace analysis.

ReArk lowers the barrier to HarmonyOS application analysis. Use it to review app security, work through HarmonyOS CTF challenges, reverse application logic, automate interactions on HarmonyOS devices, inspect runtime logs, and build your own analysis workflow.

Installation

Download and run:

ReArk-0.2.0-windows-x64-setup.exe

Feature Highlights

Package Analysis

• Supports HarmonyOS NEXT .hap, .app, and .abc files
• Browse package structure, modules, generated source output, resources, signatures, and metadata
• Inspect signatures and certificate information
• Search files and quickly open important paths from the package tree

Static Analysis

• Parse ABC files
• Disassemble and decompile ABC bytecode
• Reconstruct source structure and view disassembly or decompiled output for the corresponding source files
• Inspect ABC strings, hex content, formatted JSON, text, images, and media resources
• Use ABC trace tools for strings, literals, xrefs, call argument flows, ABC tree inspection, source reading, and disassembly reading
• Keep analysis grounded in real package clues with less note juggling and context switching

Signing And Packaging

• Configure signing materials and inspect signing validity
• Re-sign applications
• Package and install applications

ReArk Agent

• Ask contextual questions about the currently opened package
• Let the Agent inspect package metadata, files, strings, disassembly, and decompiled output when needed
• Use provider presets for OpenRouter, OpenAI, OpenAI-compatible endpoints, Anthropic, Gemini, Ollama, DeepSeek, DashScope, and Qwen
• Attach reference documents to enrich AI-assisted analysis with your own notes and materials
• Drive a full analysis flow across static review, signing and packaging, application installation, launch verification, and log tracing

Device Connection

• Discover connected HarmonyOS devices
• Install the current application to a device
• Capture screenshots, inspect UI nodes, and connect UI clues to the real device state
• Read Hilog output and perform basic UI actions such as tap, text input, Back, Home, and swipe
