ReArk

English | 简体中文

ReArk is a desktop reverse engineering and AI-assisted analysis tool for HarmonyOS NEXT, Android, and iOS applications. Open HarmonyOS .hap, .app, and .abc files, Android .apk and .aab packages, or iOS .ipa files to inspect code, resources, metadata, signatures, and application behavior in one workspace. Standalone Windows PE, ELF, and Mach-O binaries can also be opened directly for native analysis.

Combine static analysis with connected-device inspection and ReArk Agent to investigate application logic, review security, and work through CTF challenges.

Installation and platforms

Feature Highlights

Package and static analysis

Supports HarmonyOS NEXT .hap, .app, and .abc, Android .apk and .aab, and iOS .ipa files
Browse package structure, modules, generated source output, resources, signatures, and metadata
Disassemble and decompile ABC bytecode; explore strings, literals, cross-references, and call argument flows
Inspect Android manifests, permissions, components, entry points, resources, and application icons
Read Android disassembly and Java-like decompiled output
Inspect iOS IPA signatures and certificate chains
View hex data, formatted JSON, XML, text, images, and media resources; search files and navigate source output

Native binary analysis

Open Windows PE (.exe, .dll), ELF, and Mach-O executables and libraries directly
Browse headers, sections, imports, exports, relocations, and dependencies
Review security mitigations such as ASLR, DEP/NX, PIE, RELRO, stack canaries, and CFG
Navigate structure-aware listings and hex views with field-level annotations

HarmonyOS signing and packaging

Inspect signatures, certificates, and signing validity
Configure signing materials, re-sign, and repackage HarmonyOS applications
Install supported application packages on connected devices; Android device installation uses APK files

ReArk Agent

Ask contextual questions about the current HarmonyOS or Android package
Discover analysis capabilities and retrieve package files, metadata, strings, disassembly, and decompiled output as needed
Attach reference documents to supplement package evidence with your own materials
Use supported model providers, including OpenAI-compatible endpoints and local Ollama models
Combine static analysis with device workflows; host commands, Python execution, and device operations use the applicable approval flows

Connected devices

Discover HarmonyOS devices through HDC and Android devices through ADB
Install and launch applications, capture screenshots, inspect UI nodes, and read device logs
Mirror device screens in real time and control devices using mouse and keyboard
Use screen recording, audio, clipboard, and device controls where supported by the device and runtime
Work with fullscreen or detached mirroring windows

Available analysis views and device actions depend on the package format, operating system version, and device capabilities. ABC evidence tools and HarmonyOS re-signing are specific to HarmonyOS packages.
