PrepAway - Latest Free Exam Questions & Answers

A.
Kernel-mode Rootkit

B.
User-mode Rootkit

C.
Malware

D.
Kernel-mode Badware

Explanation:
A rootkit is a set of tools placed on a system that has already been compromised. The attacker usually replaces
default system tools with compromised tools, which share the same name. Most rootkits contain sniffers, so the
data can be captured and reviewed by the attacker; and “log scrubbers,” which remove traces of the attacker’s
activities from the system logs.
Incorrect Answers:
B: A user-level rootkit does not have as much access or privilege compared to a kernel-level rootkit and would
not include device drivers.
C: Malware is a very broad term that describes any software that is written to do something nefarious.
D: Kernel-mode Badware is not a valid computer term.
