Demonstrates a serious deficiency in proprietary Cisco LEAP networks. Since LEAP uses a variant of MS-CHAPv2 for the authentication exchange, it is susceptible to accelerated offline dictionary attacks.

Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack.
