How to crack WEP in less than 60 seconds.
Actually, it typically takes about 3-10 seconds to recover the WEP key.
I built it and ran it under Umbutu 6.10 using capture files from airdump-ng. Works fairly well on the neighborhood assortment of older PBI/SBC/at&t supplied 2Wire wireless routers that default to WEP encryption even though they are capeable of doing WPA and WPA2. However, it failed on an access point with custom tweaked firmware designed to discourage ARP injection, re-injetion, and flooding as airdump-ng could not get the required number of ARP replies in a reasonable amount of time.
Moral: WEP really sucks. Use WPA or WPA2 instead.
