This module exploits a firmware-level vulnerability in a variety of
|
|
802.11b devices. This attack works by sending a probe response frame
|
|
containing a NULL SSID information element to an affected device. This
|
|
flaw affects many cards based on the Choice MAC (Intersil, Lucent, Agere,
|
|
Orinoco, and the first generation of Airport cards).
