the same as evil twin fluxion but without captive portal so the victim connects to our fake Wep Wifi that accepts any password after getting disconnected from his Wpa 2 Wifi so we sniff data from the WEP Wifi to get the password that the victim has entered in clear text
Nope, it has to be an open network. The problem lies on the second message of the WEP authentication which is generated with the password, and later used for data encryption.
To achieve this somehow you need beforehand to know the password the user will use to send him the challenge encrypted, then he'll answer correctly the challenge in message 3 and that's it.
That's how WEP authentication works :(
