What form of malicious code hides itself inside the deep administrative or kernel layer of an operating system to hide active system tracking files from malware sweeps?
A. Adware Module
B. Macro Virus
C. Rootkit
D. Spyware Script
Answer: Option C
Solution (By JKSSB Mock Tests)
Rootkits modify system kernel code to hide processes, files, and network links, rendering themselves invisible to standard antivirus utilities.
Which defensive security strategy isolates an unverified, suspicious executable file inside a restricted virtual space to monitor its runtime behavior safely without risking the main host OS?
Explanation:
Sandboxing creates a secure, isolated runtime wrapper where untrusted applications can execute safely while security tools analyze their behavior indicators for anomalies.
Which antivirus analysis protocol checks for zero-day malware variants by scanning code layouts for suspicious instructions, rather than relying on established file hashes?
Explanation:
Heuristic analysis checks software patterns and rules of behavior to detect unknown zero-day malware variants that lack established signature profiles.
Which specific malware variety embeds its code inside the boot sectors of a hard drive platter or deep within the operating system core to intercept and mask its presence from security software tools completely?
Explanation:
Rootkits are stealthy malware packages built to acquire deep administrative access, altering kernel functions to render themselves invisible to standard OS monitoring utilities.
