Not quite the monitoring I’m talking about though.
Basically, it seems like this would be a nightmare for a home user to detect, but a company is probably gonna pick up on this quite quickly with snmp monitoring (unless it somehow does something to that).

Vulnerable to 20,000 misconfigurations, But squirted by 42 billion different simple checks that we all do anyway.
5 minute load greater than 80% of the number of cores? That’s an alarm…

Sure, but it’s still fairly detectable when it’s on a server at least, as long as you have monitoring. Just a bitch to pinpoint and fix.
