„KisMAC, for those who don??t know, is a wireless network discovery tool for Mac OS X. It scans for networks passively to let you know available networks, signal level and encryption type. But KisMAC doesn??t fear encrypted networks.
It is capable of cracking of WEP and WPA keys, both by brute force, and exploiting flaws such as weak scheduling and badly generated keys as well as packet reinjection.
The only problem is that the current complied version doesn??t work with Apple??s latest MacBook and MacBook Pros. We use SVN to compile the application with newly released code to support (in passive mode) the AirPort Exteme wireless cards in MacBook and MacBook Pros.
