The last line in the log is worrysome: > [2020-07-26T21:07:52,138][INFO][o.e.c.m.MetaDataCreateIndexService] [ISu\_GIR] [t19hfzgnp7-meow] creating index, cause [api], templates , shards [5]/[1], mappings See the `t19hfzgnp7-meow` index? Your cluster has been compromised by the [Meow attack](https://www.bleepingcomputer.com/news/security/new-meow-attack-has-deleted-almost-4-000-unsecured-databases/), which randomly deletes data from unsecured clusters. I would urge you to properly [secure your cluster](https://www.elastic.co/guide/en/elasticsearch/reference/current/secure-cluster.html) very quickly, especially since [Elasticsearch Security is FREE](https://www.elastic.co/blog/security-for-elasticsearch-is-now-free) as of 6.8.0 and 7.1.0. ---

You should consider upgrading to 6.8.0 if that's possible. If not, you really need to at least make sure that your cluster is not publicly accessible anymore. Also I hope you have snapshots/backups of your data that was deleted. ---
