Elastic Http Bad Request Path Probe

An HTTP GET request targeting the non-standard path /bad-request on an Elasticsearch-exposed port. This primitive represents automated protocol probing where a scanner sends intentionally invalid or placeholder paths to observe HTTP status codes and response structure. The request is not a legitimate Elasticsearch API call and is typically used during early-stage reconnaissance to confirm that the service speaks HTTP and to fingerprint error handling behavior before issuing Elasticsearch-specific queries.
