Attackers are actively scanning for vulnerable Elasticsearch systems in order to implant cryptocurrency mining scripts.

Patched Elasticsearch Vulnerabilities Used to Spread Cryptocurrency Miner (CVE-2014-3120, CVE-2015-1427)

The default configuration in Elasticsearch before 1.2 enables dynamic scripting, which allows remote attackers to execute arbitrary MVEL expressions and Java code via the source parameter to _search. NOTE: this only violates the vendor's intended security policy if the user does not run Elasticsearch in its own independent virtual machine.
