Bypass mac filter

Access points can restrict the devices that are allowed to connect to the network based on their mac address. This mac based filtering can be easily bypassed.

For instance, in the example below, we want to connect to the network with the SSID XYCompany, but we failed to authenticate.

Figure 1: Airodump-ng scan showing XYCompany

Figure 2: Authentication rejection from the AP

We can use macchanger to change our mac address for the mac address of a connected device to the targeted network. wlan1 corresponds to the interface we want to use the mac address with.

macchanger -m D2:E9:6A:D3:B3:51 wlan1

We should now be able to connect to the AP using the command shown in Figure 2.
