What is Man-in-the-Middle Attack in cyber security?

An attack where the hacker secretly intercepts communication between two parties.

A man-in-the-middle (MitM) attack occurs when a hacker secretly intercepts and potentially alters the communication between two parties without their knowledge. This can happen on unsecured networks, such as public Wi-Fi, where the attacker can eavesdrop on conversations, steal data, or inject malicious content. Using encrypted communication channels (like HTTPS), VPNs, and secure network configurations can help prevent MitM attacks and protect sensitive information.
