How Can I Tell If I've Been Affected?

Potential Indicators: 

  • Missing data indices (Elasticsearch)
  • A new index warning created asking for bitcoins to be sent to a particular location (Elasticsearch)
  • The addition of a collection called "bitcoin" (MongoDB)
  • Missing directories (Hadoop)
  • Wiping data (CouchDB)
  • Ransom demand left in place (CouchDB)



Regardless of which hosting provider you use, we strongly suggest that you follow security best practices to reduce your attack surface for MongoDB, Elasticsearch, Hadoop, and CouchDB. In addition, we recommend that customers regularly review all public-facing services and either reduce their network exposure or harden the applicable configuration.
