Final answer:
A Man in the Middle (MitM) attack involves a hacker inserting a computer between two systems that are communicating, allowing them to intercept and manipulate the data. This type of cyber attack can lead to significant security breaches and unauthorized access to sensitive information.
Step-by-step explanation:
When an attacker attempts to insert a computer between the two systems that are communicating, this kind of security breach is known as a Man in the Middle (MitM) attack. During such an attack, the hacker can intercept, send, and receive data meant for someone else without either of the legitimate parties knowing that the conversation has been compromised. MitM attacks are a serious threat in cybersecurity because they can lead to unauthorized access to personal information, breaching of confidential communications, and various kinds of fraud.
Hackers have a variety of methods to perform MitM attacks, from compromising security protocols to exploiting vulnerabilities within networks. These attacks can occur on unsecured public Wi-Fi networks, through phishing attempts that trick individuals into connecting to malicious networks, or by exploiting software vulnerabilities to insert themselves into a communication session.
