MAC filtering, or MAC white- or blacklisting, is often used as a security measure to prevent non-whitelisted or blacklisted MAC addresses from connecting to the wireless network.With MAC filtering you can specify MAC addresses which are allowed or not allowed to connect to the network.For many occasions MAC filtering can be sufficient as a security measure but in others it is certainly not.
MAC filtering is totally useless to protect company networks and data or to prevent networks from being hacked over WiFi because is it so easy to bypass. When MAC filtering is in place you can easily determine whitelisted MAC addresses by scanning for connected clients using a tool like airodump-ng. The connected clients MAC address is whitelisted, otherwise it would not have been able to connect to the wireless network. We will put our wifi adapter in monitoring mode and retrieve the MAC address of connected clients with Airodump-NG on Kali Linux. Then we will be using the Macchanger tool to spoof our MAC address, bypass MAC filtering and connect to the wireless network. Tutorial For Wurst Hacked Client April 2017 Password Is OutsideHacking the WiFi network password is outside the scope of this tutorial. Tutorial For Wurst Hacked Client April 2017 How To Retrieve TheYou can have a look at the following WiFi hacking tutorials and tools to learn how to retrieve the password (and prevent this from happening). We will be adding one client to the whitelist which will be our connected client. This tells us the MAC filtering is active and working like a charm. The second column lists the MAC Addresses of the connected client which we will be spoofing in order to authenticate with the wireless network. Lets spoof the MAC address of your wireless adapter but first we take need to take down the monitoring interface wlan0mon and the wlan0 interface in order to change the MAC address. This tutorial shows us that it was extremely easy to bypass MAC filtering on a wireless network and that MAC filtering is generally useless to protect your network from hackers. Basically, turn off your WiFi completely, then change it, then turn it on and it should change the MAC Address.
