MAC Address brute forcing tool, used to bypass MAC based filtering

Network Access Control solutions are a simple idea, 802.1X cert based authentication, great! works like a charm. However, businesses are complex beasts and not all systems on that network support 802.1X and/or cert based authenticaiton.

In this situation most look to simple MAC authentication to handle the exceptions.

So if lets say your IP phones are on the same network, if we can find the correct MAC address we can essential spoof that address and access the network.

This utility was designed for exactly this, MAC address manipulation and brute forcing.
