ABSTRACT
Additionally, the majority of rootkits are “persistent,”
whereas others are not. Persistent rootkits stay installed
regardless of how many times the systems on which they
are installed are booted. Non-persistent rootkits (also
called “memory-resident” rootkits) reside only in memory;
no file in the compromised system contains their code.
They thus remain on a victim system only until the next
time the system boots, at which time they are deleted.
