What best describes a Man-in-the-Middle (MitM) attack?

• A. Attacks That Guess Passwords by Brute Force
• B. Attacks That Cause Buffer Overflow
• C. Attacks Where an Attacker Intercepts and Alters Communication Between Two Parties Without Their Knowledge
• D. Attacks That Require Insider Access

Answer: (C)

In a Man-in-the-Middle attack, the attacker places themselves between two communicating parties and can intercept the messages as they pass by, potentially reading, altering, or impersonating a party without anyone realizing. This setup lets the attacker eavesdrop on sensitive data, inject malicious content, or change communications in transit, making the participants think they’re talking directly to each other. The key is that the interception and possible manipulation happen without the parties’ knowledge. That description matches the idea of an attacker who sits between two endpoints and changes the flow of information. By contrast, brute-force attacks are about guessing passwords, and buffer overflow attacks exploit software memory management, while insider-access attacks rely on someone with legitimate access inside the system. All of those depict different threat types, not the in-between interception and alteration that defines a MitM scenario.
