As wireless network is getting cheaper, it is getting more and more common. My laptop has the ability to scan for wireless signal. I discover two “hotspot”, one near my house, another near to my office. I have no idea where is the network but I don’t think they mean for public access. And I have been riding on their network for free Internet access.
However, I don’t dare to use this network to access Internet application (e.g. e-mail) that requires password. Coz I heard some hackers purposely setup free hotspot for others to use, then sniffing their network activities to steal our password.
