Client first performs a generic request to the Elasticsearch root endpoint to verify service availability, then proceeds to request /_cat/indices. This sequence reflects staged Elasticsearch reconnaissance where the actor validates that the cluster is reachable before attempting index enumeration and data exposure assessment. Compared to direct index enumeration behaviors, the interaction begins with a service-validation step, suggesting adaptive probing rather than immediate Elasticsearch-specific targeting.
