1Identify exposure identify
grep -r 'io.appium:java-client' . | 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 `io.appium:java-client` 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 'POST /wd/hub/session' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで `POST /wd/hub/session` 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。

7Post-deployment verification verify
Replay attack against POST /wd/hub/session on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 3 と同じログクエリでアラート再発が無いか継続監視。
