    en.wikipedia.org/wiki/MAC_spoofing

    However, this problem can be solved using MAC spoofing. The user has to spoof the new MAC address so that it appears to be the address that was in use when the software was registered. [citation needed] Legal issues might arise if the software is run on multiple devices at once by using MAC spoofing. At the same time, the user can access ...

    Conventionally it is achieved by comparing the MAC address of the participating wireless devices. Rogue devices can spoof MAC address of an authorized network device as their own. New research uses fingerprinting approach to weed out devices with spoofed MAC addresses. The idea is to compare the unique signatures exhibited by the signals ...

    Changing MAC addresses is necessary in network virtualization. In MAC spoofing, this is practiced in exploiting security vulnerabilities of a computer system. Some modern operating systems, such as Apple iOS and Android, especially in mobile devices, are designed to assign a random MAC address to their network interface when scanning for ...

    However, non-repudiation can be provided by systems that securely bind key usage information to the MAC key; the same key is in the possession of two people, but one has a copy of the key that can be used for MAC generation while the other has a copy of the key in a hardware security module that only permits MAC verification. This is commonly ...

    en.wikipedia.org/wiki/Captive_portal

    Once the IP and MAC addresses of other connecting computers are found to be authenticated, any machine can spoof the MAC address and Internet Protocol (IP) address of the authenticated target, and be allowed a route through the gateway. For this reason some captive portal solutions created extended authentication mechanisms to limit the risk ...

    All GNSS systems, such as the US GPS, Russia's GLONASS, China's BeiDou, and Europe's Galileo constellation, are vulnerable to this technique. [19] It has been suggested that in order to mitigate some of the vulnerabilities the GNSS systems face concerning spoofing attacks, the use of more than one navigational system at once is recommended. [20]

    By contrast, in ARP spoofing the answering system, or spoofer, replies to a request for another system's address with the aim of intercepting data bound for that system. A malicious user may use ARP spoofing to perform a man-in-the-middle or denial-of-service attack on other users on the network. Various software exists to both detect and ...
