Collecting the MAC Addresses by gorvam saddar

Collecting the MAC Addresses

The attacker gathers legitimate MAC addresses for use later in constructing spoofed frames. The source and destination MAC addresses are always in the clear in all the frames.  There are two reasons why an attacker would collect MAC addresses of stations and APs participating in a wireless network. 
 (1) The attacker wishes to use these values in spoofed frames so that his station or AP is not identified.
 (2) The targeted AP may be controlling access by filtering out frames with MAC addresses that were not registered.
