xmrig running - hacked or open?

Hi,

 

I noticed CPU activity at 100% this morning and "xmrig" was running.  A quick search and there are a couple of other threads of this happening to others who have opened some of their ports.

 

I've had reverse proxy set up for a good while but I don't think I have any ports open directly to the server.

 

I've attached my diagnosis file if anyone can see anything suspicious that would be much appreciated.

    4    Wireguard        51820    51820    192.168.0.5

 

These are the port forwarding rules I have.

 

The miner was running under the user "nobody" which I use for applications.

That's the full list. 

 

1&2 - Letsencrypt

3 - Sabnzbd

4 - Deluge

5 - Another torrent docker I dont use anymore

6 - Wireguard

 

I've since deleted the torrent entries.  Does leaving a FWD entry to a port that isnt in use on the internal side create a security risk?

Just to update, I think this has originated from a malicious Deluge plugin.

I think an old port fwd rule I had in exposed it. I was using a weak password on the deluge front end too. 
 

I’ve since removed the forwarding rule and changed to a more complex password too.
