Spanish B2B Information Exposed

An unprotected Elasticsearch server belonging to a Spanish B2B information provider exposed a massive collection of business records. The data breach involved sensitive company information, professional contact details, and internal business metrics. The leak occurred due to a misconfigured database that was accessible from the internet without any authentication. Security researchers discovered the open instance which contained millions of records related to Spanish enterprises and their employees, highlighting significant risks for targeted phishing and corporate espionage.
