A Man-in-the-Middle (MITM) attack is a cyberattack in which an attacker secretly intercepts and, in some cases, alters the communication between two parties without their knowledge. The attacker positions themselves between the sender and the receiver, making both parties believe they are communicating directly with each other. This type of attack can lead to theft of sensitive information such as usernames, passwords, banking credentials, personal data, and confidential business information. MITM attacks are commonly associated with insecure networks, compromised routers, public Wi-Fi hotspots, and weaknesses in network protocols. Ettercap is a well-known network security assessment tool used by security professionals for testing the security of local area networks. It supports packet analysis, protocol inspection, and security auditing. In authorized penetration testing environments, Ettercap can be used to demonstrate how MITM attacks work so that organizations can identify vulnerabilities and strengthen their defenses. It should only be used with proper authorization because using it against networks without permission is illegal and unethical. In a typical demonstration, Ettercap illustrates how an attacker may intercept network
