Android Reverse Engineering Skill — インストール & ライブデモ

なぜ使うのか

主な機能

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

インストール

クライアントを選択

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "android-reverse-engineering-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/SimoneAvogadro/android-reverse-engineering-skill",
        "~/.claude/skills/android-reverse-engineering-skill"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config を開く。保存後、アプリを再起動。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "android-reverse-engineering-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/SimoneAvogadro/android-reverse-engineering-skill",
        "~/.claude/skills/android-reverse-engineering-skill"
      ],
      "_inferred": true
    }
  }
}

Cursor は Claude Desktop と同じ mcpServers スキーマを使用。プロジェクト設定はグローバルより優先。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "android-reverse-engineering-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/SimoneAvogadro/android-reverse-engineering-skill",
        "~/.claude/skills/android-reverse-engineering-skill"
      ],
      "_inferred": true
    }
  }
}

Cline サイドバーの MCP Servers アイコンをクリックし、"Edit Configuration" を選択。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "android-reverse-engineering-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/SimoneAvogadro/android-reverse-engineering-skill",
        "~/.claude/skills/android-reverse-engineering-skill"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop と同じ形式。Windsurf を再起動して反映。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "android-reverse-engineering-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/SimoneAvogadro/android-reverse-engineering-skill",
        "~/.claude/skills/android-reverse-engineering-skill"
      ]
    }
  ]
}

Continue はマップではなくサーバーオブジェクトの配列を使用。

~/.config/zed/settings.json

{
  "context_servers": {
    "android-reverse-engineering-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/SimoneAvogadro/android-reverse-engineering-skill",
          "~/.claude/skills/android-reverse-engineering-skill"
        ]
      }
    }
  }
}

context_servers に追加。保存時に Zed がホットリロード。

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

ワンライナー。claude mcp list で確認、claude mcp remove で削除。

ユースケース

実用的な使い方： Android Reverse Engineering Skill

Bypass cert pinning on a test app for MITM analysis

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

使うタイミング： You need to inspect a Flutter/OkHttp app's traffic and pinning blocks Burp.

前提条件

Server/skill installed and authenticated — See repo README

フロー

Identify pinning

Decompile target.apk and find all references to TrustManager / CertificatePinner / Flutter's HttpClient.✓ コピーしました

→ List of hooks to patch
Patch + Frida

Generate a Frida script that no-ops checkServerTrusted across both Java and Flutter paths.✓ コピーしました

→ Frida .js + run command

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

注意点

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.

コストと制限

運用コスト

APIクォータ: See provider docs for rate limits
呼び出しあたりのトークン: Varies by tool
金額: See repo README for pricing details
ヒント: Cache tool results and avoid repeated identical calls.

セキュリティ

権限、シークレット、影響範囲

認証情報の保管： Use environment variables; never commit secrets

データ送信先： Tool calls go to the provider's API as documented

トラブルシューティング

よくあるエラーと対処法

apktool fails to unpack

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

確認： apktool --version ≥ 2.9

repack signs but won't install

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

確認： adb install -r app-signed.apk

代替案

Android Reverse Engineering Skill 他との比較

代替案	代わりに使う場面	トレードオフ
trailofbits/skills	You want broader security skills	More generic; less Android-specific
