# Netflix MSL Capture — Proxyman Script + Addon
|
||||
|
||||
Netflix の MSL (Media Service Layer) トラフィックをキャプチャ・解析する Proxyman スクリプト。
|
||||
|
||||
## 機能
|
||||
|
||||
- **MSL メッセージデコード**: base64 / LZW エンコードされたエンベロープをデコード
|
||||
- **リクエストボディ解析**: MSL リクエストのパラメータをデコード・保存 (マニフェスト要求の詳細が見える)
|
||||
- **マニフェスト抽出**: 動画/音声トラック情報 (解像度, ビットレート, コンテンツプロファイル, DRM KID)
|
||||
- **HTTP マニフェスト API キャプチャ**: `/playapi/cadmium/manifest/1` (非 MSL) をキャプチャ
|
||||
- **licensedmanifest キャプチャ**: `/msl/playapi/cadmium/licensedmanifest/1` の MSL エンベロープ解析
|
||||
- **ALE 鍵抽出**: CLEAR スキームの provisioning レスポンスから HMAC/AES 鍵を検出
|
||||
- **ESN 取得**: デバイス識別子 (Electronic Serial Number) をヘッダー / sender から抽出
|
||||
- **KID テーブル生成**: 解像度ごとの DRM Key ID 一覧を Markdown テーブルで出力
|
||||
- **全トラフィックログ**: JSONL 形式で全 MSL 通信を記録
|
||||
|
||||
## 前提条件
|
||||
|
||||
- **Proxyman v3.6.2 以上** (`writeToFile` / `readFromFile` API が必要)
|
||||
- Proxyman の SSL Proxying が `*.netflix.com` に対して有効であること
|
||||
|
||||
## インストール
|
||||
|
||||
### 1. アドオンの配置
|
||||
|
||||
```bash
|
||||
# Proxyman のカスタムアドオンフォルダを開く
|
||||
# Proxyman > More > Documentations > Open Custom Addons Folder
|
||||
# または直接:
|
||||
cp addons/NetflixMSLParser.js \
|
||||
~/Library/Application\ Support/com.proxyman.NSProxy/users/NetflixMSLParser.js
|
||||
```
|
||||
|
||||
### 2. スクリプトの設定
|
||||
|
||||
#### スクリプト A: MSL トラフィック (既存)
|
||||
|
||||
1. Proxyman を開く
|
||||
2. **Script Menu** > **Script List** (`Option + Cmd + I`)
|
||||
3. **+** ボタンで新規スクリプト作成
|
||||
4. **URL Matching Rule**: `*netflix.com/nq/msl_v1/*`
|
||||
5. `netflix-msl-capture.js` の内容をスクリプトエディタに貼り付け
|
||||
6. **Enable on Request** ✓ にチェック
|
||||
7. **Enable on Response** ✓ にチェック
|
||||
|
||||
#### スクリプト B: HTTP マニフェスト API (StreamFab 等)
|
||||
|
||||
1. **+** ボタンでもう一つ新規スクリプト作成
|
||||
2. **URL Matching Rule**: `*netflix.com/*manifest*`
|
||||
3. `netflix-manifest-http-capture.js` の内容をスクリプトエディタに貼り付け
|
||||
4. **Enable on Request** ✓ にチェック
|
||||
5. **Enable on Response** ✓ にチェック
|
||||
|
||||
### 3. 出力ディレクトリ
|
||||
|
||||
デフォルトでは `~/Desktop/netflix-msl-capture/` に自動作成されます。
|
||||
スクリプト冒頭の `OUTPUT_DIR` で変更可能:
|
||||
|
||||
```javascript
|
||||
const OUTPUT_DIR = "~/Desktop/netflix-msl-capture";
|
||||
```
|
||||
|
||||
## 出力ファイル構成

||||

|
||||
|
||||
## トラブルシューティング
|
||||
|
||||
### `writeToFile` が動作しない
|
||||
- Proxyman v3.6.2 以上か確認: **Proxyman > About Proxyman**
|
||||
- ファイルパスに `~` を使用可（Proxyman が展開）
|
||||
|
||||
### MSL ペイロードがデコードできない
|
||||
- SSL Proxying が有効か確認: **Certificate > Install Certificate on this Mac**
|
||||
- Netflix アプリが Proxyman の CA 証明書を信頼しているか確認
|
||||
- 暗号化スキームが CLEAR でない場合、ペイロード内容は暗号化されたまま（エンベロープの headerdata は読める）
|
||||
|
||||
### アドオンが見つからない
|
||||
- `@users/` フォルダにファイルがあるか確認
|
||||
- ファイル名が正確に `NetflixMSLParser.js` であるか確認
|
||||
- Proxyman を再起動
