The correct answer is B. They allow an attacker to replace utility programs that can be used to detect the attacker's activity. C. They allow an attacker to set a Trojan in the operating system and thus open a backdoor for anytime access. D. They allow an attacker to run packet sniffers secretly to capture passwords. Rootkits are post-exploitation toolkits that provide persistent, hidden access by subverting OS utilities, installing backdoors, and concealing attacker processes - but they do not themselves perform initial exploitation techniques like buffer overflows.

Why each option

Rootkits are post-exploitation toolkits that provide persistent, hidden access by subverting OS utilities, installing backdoors, and concealing attacker processes - but they do not themselves perform initial exploitation techniques like buffer overflows.

AThey allow an attacker to conduct a buffer overflow.

Buffer overflow is an initial exploitation technique used to gain code execution or escalate privileges; it is a separate attack vector and not a capability that a rootkit provides once installed.

BThey allow an attacker to replace utility programs that can be used to detect the attacker's activity.Correct

A core rootkit capability is replacing or trojaning system binaries (such as ps, ls, and netstat) so that the attacker's files, processes, and network connections are hidden from administrators and security tools.

CThey allow an attacker to set a Trojan in the operating system and thus open a backdoor for anytime access.Correct

Rootkits commonly embed Trojan components or backdoor services directly into the operating system, enabling persistent covert re-entry for the attacker at any time without re-exploiting the system.

DThey allow an attacker to run packet sniffers secretly to capture passwords.Correct

Because rootkits can suppress process and file visibility at the kernel or user level, they allow packet sniffers to run invisibly, capturing passwords and sensitive network data without triggering detection.
