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

  • This sounds like a mix of a downgrade and de-authentication attack... clever.

  • Mod your own WRT WAP to do it?

  • i believe WEP keys are used to encrypt the contents, so if the password is wrong, communication can't happen. You might still be able to sniff out the password, but it won't be easy to avoid arousing suspicion as the user's password won't actually work and the OS will complain.

  • @dandavis "You might still be able to sniff out the password" as long as we sniff the correct password ... the rest is no problem...

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 :(

  • TBH I can't think of any way this can be achieved... other than open network with captive portal, then after the user inputs the password, change the open network to shared key with the password the user inputs.... but it's to troublesome, and quite fishy for the user.

  • This is a WEP Downgrade Attack, and it uses social engineering. Social engineering you can also trick the user into connecting into an open network and show a captive portal telling him to put his WEP password. Or whatever you feel like.
