What is a 'man-in-the-middle attack'?

• A. An attack that spreads through social engineering
• B. An attack where the attacker intercepts communication between two parties without their knowledge
• C. An attack that involves taking control of a computer system
• D. An attack that infects software with malware

Answer: (B)

A 'man-in-the-middle attack' is characterized by the attacker secretly intercepting and possibly altering the communication between two parties who believe they are directly communicating with each other. This form of attack allows the attacker to eavesdrop on conversations and manipulate messages, all while remaining undetected by the victims. By placing themselves between the two communicating parties, the attacker can collect sensitive information such as passwords, credit card numbers, or other personal data. In contrast, the other options describe different types of attacks. For instance, social engineering attacks primarily involve manipulation or deception to trick individuals into divulging confidential information, rather than intercepting communication directly. Control over a computer system is indicative of a system compromise rather than the interception aspect central to a man-in-the-middle attack. Similarly, infecting software with malware pertains to a different attack vector, focusing on compromising systems through malicious software rather than intercepting communications themselves.
