Android Reverse Engineering Skill

Name: Android Reverse Engineering Skill (Claude Skill)
Author: SimoneAvogadro

por SimoneAvogadro · SimoneAvogadro/android-reverse-engineering-skill

Claude Code skill for Android APK reverse engineering — apktool, jadx, Frida workflows.

A skill bundle that teaches Claude how to do real Android reverse engineering: unpack APKs, decompile to Java with jadx, patch smali, hook with Frida. It chains the right tools instead of one-shotting jadx and giving up.

Por que usar

Principais recursos

End-to-end workflow: pull APK → unpack → decompile → search → patch → repack → sign
Frida script scaffolding for runtime hooks
Smali patching with checksum-safe repack
Built-in checklists for common targets (cert pinning, root detection)
Pairs with a bin/ toolchain bootstrap

Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

Clique no ícone MCP Servers na barra lateral do Cline, depois "Edit Configuration".

Mesmo formato do Claude Desktop. Reinicie o Windsurf para aplicar.

O Continue usa um array de objetos de servidor em vez de um map.

          "~/.claude/skills/android-reverse-engineering-skill"
        ]
      }
    }
  }
}

Adicione em context_servers. Zed recarrega automaticamente ao salvar.

claude mcp add android-reverse-engineering-skill -- git clone https://github.com/SimoneAvogadro/android-reverse-engineering-skill ~/.claude/skills/android-reverse-engineering-skill

Uma linha só. Verifique com claude mcp list. Remova com claude mcp remove.

Casos de uso

Usos do mundo real: Android Reverse Engineering Skill

Bypass cert pinning on a test app for MITM analysis

👤 Security researchers (with permission!) ⏱ ~15 min intermediate

Quando usar: You need to inspect a Flutter/OkHttp app's traffic and pinning blocks Burp.

Pré-requisitos

Server/skill installed and authenticated — See repo README

Fluxo

Identify pinning

Decompile target.apk and find all references to TrustManager / CertificatePinner / Flutter's HttpClient.✓ Copiado

→ List of hooks to patch
Patch + Frida

Generate a Frida script that no-ops checkServerTrusted across both Java and Flutter paths.✓ Copiado

→ Frida .js + run command

Resultado: Working MITM channel on a test target you own.

Armadilhas

Reversing apps you don't have rights to is illegal in most jurisdictions. The skill assumes you've documented authorization. — Reversing apps you don't have rights to is illegal in most jurisdictions. The skill assumes you've documented authorization.

Custo e limites

O que custa rodar

Cota de API: See provider docs for rate limits
Tokens por chamada: Varies by tool
Monetário: See repo README for pricing details
Dica: Cache tool results and avoid repeated identical calls.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: Use environment variables; never commit secrets

Saída de dados: Tool calls go to the provider's API as documented

Solução de problemas

Erros comuns e correções

apktool fails to unpack

Use the latest apktool (≥2.9). Older versions miss new resource tables.

Verificar: apktool --version ≥ 2.9

repack signs but won't install

Use uber-apk-signer with --allow-resign and target the right SDK level.

Verificar: adb install -r app-signed.apk
