Editing MAC Addressing (section)

== MAC Spoofing ==

Despite being "hardcoded," MAC addresses can be changed (spoofed) in software. This is known as '''MAC spoofing'''.

=== Why Spoof a MAC Address? ===

* Bypass MAC-based filtering (e.g. in cafés, hotels)
* Mimic trusted devices to gain access in misconfigured firewalls
* Circumvent "one device per user" limits on public Wi-Fi
* Preserve anonymity on monitored networks

=== Example Scenario ===

A firewall is configured to allow traffic only from the MAC address of the administrator.  
If an attacker spoofs that MAC address, the firewall might wrongly allow unauthorized access.
