What type of attack intercepts and alters communication between two parties without their knowledge?

A Man-in-the-Middle (MitM) Attack occurs when an attacker secretly intercepts and potentially alters the communication between two parties without their awareness. This is typically achieved by placing the attacker in the communication path, which allows them to capture and manipulate data being sent between the two parties.

For example, in a MitM attack, an attacker could intercept messages sent between a user and a website, allowing them to eavesdrop, modify the content, or impersonate one of the parties involved. This type of attack often leverages vulnerabilities in network protocols or insecure Wi-Fi connections to position itself between the communicating parties.

Understanding the nuances of this attack is vital for cybersecurity as it emphasizes the need for encryption and secure communications. By focusing on secure protocols like HTTPS or utilizing Virtual Private Networks (VPNs), users can safeguard against such interceptive tactics. Additionally, awareness of the potential for MitM attacks is essential when connecting to public networks, highlighting the importance of verifying SSL certificates and employing other security best practices.
