------------------------------------

             Summary: solr user used for crypto mining hack
                 Key: SOLR-12700
                 URL: https://issues.apache.org/jira/browse/SOLR-12700
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: 6.6
         Environment: Ubuntu running Solr 6.6
            Reporter: Robert Gillen


I am struggling to fight an attack were the solr user is being used to crate 
files used for mining cryptocurrencies. The files are being created in the 
/var/tmp and /tmp folders.

It will use 100% of the CPU. 

I am looking for help in stopping these attacks.

All files are created under the solr user.

Any help would be greatly appreciated.
