I run plex on proxmox. When I woke up I noticed my proxmox server was using a lot more cpu than usual.

Then, plex was using all the resources it was provisioned for. So I checked out what was running and it was a weird process. I tracked down some logs and found the intrusion. IPs related to it etc. but I just blew up the lxc. Saved a copy of the malicious programs and the logs to dig into. Spun up a new plex from the previous days backup.
