Man in the middle attack is an attack where the attacker secretly relays and possibly alters the communications between two parties. When data is sent between a computer and a server, a cybercriminal can get in between and spy or eavesdrop.
A man in the middle attack can positions himself in a conversation between a user and an application in other to impersonate one of the parties, making it appear as if a normal exchange of information is underway.
In a man-in-the-middle cyber-attack, the attacker places themselves in between two devices and monitor packets from the network, modifies them, and inserts them back into the network without the other parties knowing.
