Eleventh is a proof of concept ruby-based IEE802.11 WEP password cracker inspired by wepattack.
It uses a pre-defined dictionary to guess known vulnerable WEP passwords based on their BSSID and ESSID.

It requires only a single encrypted IEE802.11 WEP data frame to test against a targeted network and verify the validity of a passphrase.
