I never use free wireless networks, but those netbooks look terribly cute, and I suspect I'll eventually own one. (Their origin was recently discussed at LP.)
Anyhow, the Sydney Morning Herald points out the security risks in using them that way:
...anyone who knows how to use Google can find step-by- step instructions on how to set up a wireless trap.Well, I guess I know now how to be careful when using these, but I bet this takes a while to become common knowledge.All one needs to do is find a place where tourists congregate, like a McBurger joint, and set up a wireless networking relay station on a laptop. When the tourist goes to log on to the free wireless, they can be easily duped into logging on to a bogus network.
This could be as simple as calling the fake network "McBurger Free Network". It looks and sounds legit and because the repeater computer is close by, it will likely have the strongest signal of all available networks.
It doesn't help that many networks don't use descriptive names, making the fakes seem even more authentic. Once connected, everything the tourist's computer transmits can be captured and recorded. While you sit digging the free wireless, bad guys are cleaning out your bank account.
This con also works if the bogus "hotspot" is not free because all the crooks have to do then is set up a phony payment page that captures credit card numbers. Yikes!
