[hungna]

Hi all,
I have 2 proxmox test machines and join the cluster, I check there is 1 machine running abnormally CPU always says >80% even though I haven't installed any VM. I test yes Command: xMEu is always running very high and can't stop it. How can I remove it?

Maybe your host is compromised and runs some cryptomining malware?

You can check the output of ps -f -p 14597 and lsof -p 14597. Maybe you can guess something from the process name or the open files.

Also you might want to check open connections to your system ss -tupen

You still should try to find out what that program came from. If your host really got compromised you should wipe the entire server.
