So today I noticed 4 of the 8 threads on my UnRaid server was running pinned at 100%. At first I thought it was one of my VMs running screwy, but instead I found a docker container I'd never seen before.
It was named gallant_snyder and it was running xmrig which appears to be a crypto-miner.
The really odd thing is that I've haven't installed any new docker containers or community apps in years, just updated the ones I started with. So I'm really worried now wondering how it got installed in the first place.
Docker Containers:
NoIp
iPXE-buildweb
Apps:
Community Apps
CA Fix Common Problems
Dynamix Local Master
Dynamix SSD Trim
Disable Security Mitigations
Dynamix System Info
Preclear Disk
Wake On Lan
Any ideas how this may have happened? Any steps I should take to prevent this?
