Man in the middle attack
Man-in-the-Middle Attack generally abbreviated as MitM, In computer security a man-in-the-middle attack is an attack where the attacker secretly relays and possibly alters the
communication between two parties who believe they are directly
communicating with each other. One example of man-in-the-middle attacks is active eavesdropping,
in which the attacker makes independent connections with the victims
and relays messages between them to make them believe they are talking
directly to each other over a private connection, when in fact the
entire conversation is controlled by the attacker.
