I think you have been infected by a bitcoin miner.  
see [https://discourse.nodered.org/t/crypto-miner-abuse-malware/](https://discourse.nodered.org/t/crypto-miner-abuse-malware/)

If you are exposing Node-RED on the internet you REALLY need to secure it properly.

The docs: [https://nodered.org/docs/security](https://nodered.org/docs/security) explain how to secure the editor.
