Just morbidly curious, what did you use for the SSID?

They should at least consider providing an option to disable the static pin only or disable it after an hour if the 
future is activated by the user.

Seems to be something that could be included in a future firmware update.

For a vendor to provide another mechanism for a user to get remotely hacked (within wireless TX/RX range) and not 
address it in a reasonable amount of time, exposes the less technical user, who is was intended to help in the first 
place.

It would be interesting to see if this feature went through a technical security risk assessment and if so, how the 
static pin was rationalised for public release.

I setup an isolated vulnerable device and had attack traffic within 2 days of it being activated. I did make the SSID 
very attractive, but the war drivers are certainly getting out of the house again.


Thanks

I've tested a 6 models of Linksys, all of them appear to disable WPS
completely as soon as a single wireless setting is set. I assume this
would be the reason Cisco/Linksys aren't putting much stock in
'fixing' it further. If anyone has any experience to contradict this
or have a modification to current tools to circumvent what I've
perceived as disabled, I, as I'm sure Craig, would be very interested.

"Fixing?  Heh.

Aside from rate limiting WPS, there isn't much of a fix, and you can't turn it off either."

What about removing WuPS entirely?

WuPS is a total failure because:

1. Even if everything is fine 8 digits long is very weak because once you got the pin after 7 month - 2 years for 
example, you are completely pwned.

2. Pin number is fixed you can't change it to a longer number or maybe a string like "omgponnies"

3. Setting up a WPA2 password manually it's a piece of cake (even with keypad only cell phones), if some people 
are lazy, you don't have to weakening the security of a strong protocol.
