1Identify exposure identify
grep -r 'windmill-api' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で `windmill-api` を grep し、稼働しているサービス・バージョンを把握する。

3Hunt for indicators of compromise detect
grep 'GET /api/w/{workspace}/scripts/list_search' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで `GET /api/w/{workspace}/scripts/list_search` への異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。
