Default Convenience Vs. Security - A tale of wireless networks [TCMS]

Knew WEP was easy to crack, never knew WPS had such a big loop hole!

The Computer Made Simple » Convenience Vs. Security

The whole point of WPS (Wi-Fi Protected Setup) is to make it easy to sync up multiple devices with your router. The router, in order to accept someone using WPS, will share a PIN (hard coded into the router) of 8 numbers. Well turns out it doesn’t matter if you are using WPA or WPA2, because the attack targets the router’s WPS system and not the wireless network’s encryption.

My System Specs


[Not an April fools joke]
Thanks for posting this easier-to-read article since I didn't look at the vulnerability properly the last time I read it...

Hmm so disabling WPS on my router (WRT610N) doesn't do anything
I guess most of my "security" comes from transmit power set at the minimum that I need for all the nodes to connect and that my next door neighbour uses WEP.
I also have enough hardware lying around here to implement something crazy like RADIUS but if it's attached to my router anyway that'd be useless as well. Options options...

This has been known for a bit, security for homes these days seems to be smoke and mirrors for the most part. it might seem like overkill but the best way to secure a wifi connection is separating the wifi network and running a vpn tunnel for your local data. that way you don't care what security your wifi is running. The other scary trick is to clone the SSID of a target and then running network sniffing on any packets going through or even cloning websites to capture https info like banking logins and passwords. So you shouldn't even auto connect on your devices because you might not be connecting to your own network.

NM this was wasn't the one I was thinking about, there was another attack on the WPS system using the same weak set up. 2nd scenario is this one.
