A website with info (in the form of a pdf from defcon,) and a zipped tool (Use at your risk) that allow you to bypass authentication on wireless networks by piggybacking an already authenticated user's Network IP and MAC address. Interesting read, just on the relative insecurities of these WIFIs... I mean, there is just a short step to move from this to packet surfing on these same networks. The flipside to this would be using this tool on an
open network to sub your packets in parallel with an "innocent" user. With the children of
"carnivores" in place in ISP's to monitor network activity, it is dangerous to surf, read email, post on usenets, etc if you are shady and have evil intent. With this, your shady activity points to Joe Sixpack surfing for porn.
