Anyone interested in network security in general and WiFi security in particular will find the recent thread about WEP cracking on the bcm43xx-dev list interesting. I’ve always know that cracking WEP is easy, but not that easy.
I can also recommend Cedric Blancher’s recent SecureCon talk (linked from the mail) as it’s fairly interesting. Also linked from the mail is Wifitap which is
a proof of concept for communication over WiFi networks using traffic injection.
You should especially check out the video cracking WEP in 10 easy steps linked to from the Wifitap site. When you’ve done that, reconfigure your access point to use WPA instead. Then read the end of the thread discussing how to crack WPA and return to your AP’s configuration and set a better password.
