In a MitM scenario, what do the two communicating parties believe?

• A. They believe they are communicating directly with each other.
• B. They believe they are communicating through a secure proxy.
• C. They believe the attacker is a third party.
• D. They believe the messages are encrypted with AES.

Answer: (A)

In a Man-in-the-Middle scenario, the two parties believe they have a direct connection with each other. The attacker sits between them, secretly relaying (and potentially altering) messages without either party realizing the interception. This illusion of a direct channel is what makes MitM so dangerous—each side trusts they’re talking straight to the other, while the attacker controls the path. The other ideas don’t fit because they imply awareness of an intermediary or a different security arrangement, whereas the defining point here is the mistaken belief of a direct, unobstructed link. Encryption may be present, but it doesn’t change the fact that the participants think they’re communicating directly with one another.
