About The Project Elasticsearch is a key component in many backend centralized logging stacks. Several Open Source and commercial software appliances leverage Elasticsearch in one way or another. This is especially true for the SIEM space. While there are many blogs on how to assess/extract data from an Elasticsearch cluster during a pentest/red team assessment, I have not seen a lot of conversations on how the discovery of an Elasticsearch server can be leveraged beyond just dumping data.
