Show answer
Answer: C
Explanation
Fileless malware often uses legitimate system tools, such as PowerShell, to run malicious code directly in memory without dropping traditional executable files on disk. In this case, the command includes a PowerShell script that is being executed without the need for a separate executable file, making it characteristic of a fileless attack.
