Arman transferred some money to his friend's account using a net banking service. After a few hours, his friend informed him that he hadn't received the money yet. Arman logged on to the bank's website to investigate and discovered that the amount had been transferred to an unknown account instead. The bank, upon receiving Arman's complaint, discovered that someone had established a station between Arman's and the bank server's communication system. The station intercepted the communication and inserted another account number replacing his friend's account number. What is
such an attack called?
The scenario described is a classic example of a Man-in-the-Middle (MitM) attack. In this type of cyberattack, the attacker secretly intercepts and possibly alters the communication between two parties who believe they are directly communicating with each other. The attacker has inserted themselves between the two parties, in this case, Arman and the bank's server, and has intercepted the communication to redirect the funds to a different account. This type of attack can occur in various forms, such as eavesdropping on or altering the communication over an insecure network service, but it is characterized by the attacker's ability to intercept and modify the data being exchanged without either legitimate party noticing.
