A man-in-the-middle attack is a cybersecurity breach where an attacker intercepts and relays messages between two parties who believe they are communicating directly with each other. This kind of attack allows the perpetrator to eavesdrop, alter communication, or impersonate one of the parties, posing significant risks to the integrity and confidentiality of data. In the context of smart grids, such vulnerabilities can compromise critical infrastructure, leading to unauthorized access and potential manipulation of power systems.
