Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Ransomware
Why it's wrong here
Ransomware encrypts files and demands payment; it may communicate but usually on different ports.

Why it's wrong here
Keyloggers record keystrokes but typically do not cause high CPU or outbound connections on port 4444.

Remote Access Trojan (RAT)
Why this is correct
