Computer Hacking Forensic Investigator (CHFI v10) — Question 284

A breach resulted from a malware attack that evaded detection and compromised the machine memory without installing any software or accessing the hard drive.
What technique did the adversaries use to deliver the attack?

Answer options

• A. Trojan
• B. JavaScript
• C. Spyware
• D. Fileless

Correct answer: D

Explanation

The correct answer is D, as fileless attacks operate directly in the system's memory and do not involve traditional file-based malware. Options A (Trojan), B (JavaScript), and C (Spyware) generally rely on files or installations, which contradicts the scenario described.
