Yes, but they replace common tools like top or lsof with manipulated versions. This might at least trick less experienced sysadmins.

Edit: Some found out about the vulnerability by ressource alerts. Probably very easy in a virtualized environment. The malware can't fool the hypervisor ;)

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).
