Program to get alternate mac address7/11/2023 On wireless networks, sharing the same MAC-address usually do not lead to the same problems as on a wired network. This blog post demonstrate how the network can become unreliable for devices that share the same MAC-address. ![]() If multiple ports have the same MAC-address, the network logs might contain warnings of MAC-flapping and alert the administrator. On wired networks, switches are usually only designed to forward traffic destined MAC-address to one port. This is a relatively easy process, but can cause harm (Denial of Service), depending on network equipment and configuration. Since MAC-filtering is (usually) only tied to the MAC-address assigned to a network interface controller, you can change your MAC-address to match the one of an unfiltered device. ![]() Joke aside, MAC spoofing is a way to overcome MAC filtering. ![]() If you cannot wait for the time-based attack to succeed, you can use a side channel attack and connect to the internet via an alternative channel, such as GSM or a friendly neighbor. In a timing-attack, you wait for a sufficient time, your brother will remove the MAC filtering for your device. You can defeat your brother's access restrictions, either by a timing-attack or side-channel attack.
