Using easily available tools, a moderately skilled attacker can "spoof" or clone a permitted MAC address onto their own device, bypassing the filter entirely. Furthermore, the Deco M4’s interface does not alert the user to such spoofing attempts. Consequently, relying solely on MAC filtering is akin to using a flimsy padlock on a fence—it stops the honest opportunist but not a determined intruder.
