However, the process would stop immediately when I logged in via SSH or console. As soon as I logged out, the malware would resume running within a few seconds

OK so you just need to stay logged in - Solved :)

The malware also uses advanced evasion techniques, such as suspending its activity when it detects a new user in the btmp or utmp files and terminating any competing malware to maintain control over the infected system.

So, is it a fairly decent antivirus mixed in with all the malware?

Honestly, if true, it's so insidious

Maybe not related but I had an issie with wireplumber where it would suddenly take up any free CPU resources and use them up, jacking up my cpu usage up to crazy high numbers, often to 100% at times where the expected cpu usage would be at 20% at most.

I haven't experienced this in the last week or so, so maybe it was fixed in an update? I'm on Fedora, btw. I just wanted to share, so I can find out if anyone else had the same issue.

Surely y'all have monitoring and alerts for excessive cpu load already?

I will never understand people using 3rdparty MQ and RPC implementations. What a a PR for rocketMQ right here.

You can and you should implement your communication protocols, most of the time 3rdparties are very wasteful and a security liability. I like ZeroMQ (https://zeromq.org/), they have amazing tech guides (https://zguide.zeromq.org/). I still mostly do my own code.

I may have trust issues but sockets are not THAT hard, they're just amzaingly frustrating to debug, not as much as debuging 3rdparty code.
