Nowadays, there's only one rootkit that can hide itself so perfectly: the Singularity rootkit. It also hides from auditd by using netlink_unicast hooking and other evasive functionalities. Analyzing a machine compromised with Singularity loaded is a real headache, since it prevents memory dumps for analysis.
