SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question

Exhibit

Administrator checks a suspected host:
tasklist /svc | findstr vpn
(no output)

netstat -ano | findstr 51433
TCP    0.0.0.0:51433     0.0.0.0:0     LISTENING     4

driverquery /v | findstr /i kbdflt2
kbdflt2.sys    Unknown    C:\Windows\System32\drivers\kbdflt2.sys

EDR note:
Process enumeration from user mode does not match kernel event telemetry.

Based on the exhibit, which malware type best explains the behavior?

⚠ Common exam trap

Candidates often confuse a rootkit's stealth capabilities with a Trojan's deceptive delivery method, failing to recognize that the exhibit's focus on hiding and persistence at the OS level is unique to rootkits, not general malware types.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Rootkit

A rootkit is designed to hide its presence and the presence of other malware by modifying the operating system's kernel or system calls, allowing it to evade detection by security tools. The exhibit likely shows behavior such as file hiding, process concealment, or system call interception, which are hallmarks of rootkit activity. This aligns with the SY0-701 objective on understanding malware types and their characteristics.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Trojan

    Why it's wrong here

    A trojan is malicious software that disguises itself as a legitimate application to trick a user into installing it, often relying on social engineering. The exhibit, however, shows active concealment at the kernel level — an unsigned driver, a hidden listener tied to PID 4, and conflicting user-mode versus kernel telemetry. This behavior is the defining trait of a rootkit, not the initial-vector deception that characterizes a trojan.

  • Rootkit

    Why this is correct

    The exhibit shows a hidden listener associated with PID 4, an unsigned driver, and a mismatch between user-mode process enumeration and kernel telemetry. Those are classic rootkit indicators because rootkits operate at a low level to conceal processes, ports, or files from standard tools. The suspicious driver name and kernel-level inconsistency are especially strong clues that the malware is trying to hide itself from the operating system and defenders.

  • Logic bomb

    Why it's wrong here

    A logic bomb lies dormant until a specific condition or date/time triggers a destructive payload, such as file deletion, encryption, or disruption. Nothing in the exhibit indicates a delayed or conditional trigger; instead, the malware is actively running and actively hiding its presence through kernel-level mechanisms. The exhibit’s signature is ongoing stealth and communication, not the scheduled detonation that defines a logic bomb.

  • Spyware

    Why it's wrong here

    Spyware is typically user-mode software focused on covertly capturing data — keystrokes, credentials, browsing activity — and exfiltrating it to an attacker. While stealthy, spyware rarely installs unsigned kernel drivers or causes the System process (PID 4) to host hidden network listeners, which are hallmarks of a rootkit subverting the operating system’s own reporting. The exhibit demonstrates concealment from security tooling at a fundamental layer, far beyond spyware’s data-gathering scope.
