Intercept: How MITM Attacks Work in Ethernet, IPv4 & IPv6

The article examines Man-in-the-Middle (MITM) attacks in Ethernet, IPv4, and IPv6 networks. MITM attacks involve an attacker intercepting communications between two parties without their knowledge. In IPv4 networks, ARP spoofing is a common technique where falsified ARP messages link the attacker's MAC address with the IP address of a legitimate device, allowing traffic interception. For IPv6 networks, the article details NDP spoofing, which manipulates the neighbor cache via falsified NDP messages to redirect traffic. The article also discusses MAC flooding, which overwhelms network switches, forcing them to broadcast traffic to all ports, facilitating interception. Tools like Ettercap and Bettercap are mentioned for automating these attacks. The implications of MITM attacks include data theft, session hijacking, and unauthorized access to sensitive information. Understanding these techniques is crucial for developing effective countermeasures. However, as the full article was not accessible for direct reference, this analysis is based solely on the summary provided. Some technical details and nuances may not be fully captured.
