Which type of malware is specifically used to deliver other malware?

Downloaders are malware whose primary job is to retrieve and install additional payloads. They are frequently used as a first-stage infection because the initial file can be small and then pull ransomware, RATs, infostealers, or other malware after execution. Option C (Downloaders) is correct because a downloader's purpose is specifically to deliver other malware.

Why the other options are incorrect:

A. RAT: A remote access trojan gives an attacker interactive control over a compromised host after infection.

B. Maldocs: A malicious document uses macros, embedded objects, or exploit content to run code when opened.

D. Exploitation tool: An exploitation tool attacks a vulnerability. A downloader is the malware type whose purpose is to fetch and install additional malware.
