Will Wi-fi ever be secure?
The hacking technique is dubbed "Evil Twin" because scammers set up a bogus wireless access point near a legitimate base station that they then jam. Users within range of the sham access point connect to it thinking that it's a real link to the Net. All the time, however, the information transmitted over the wireless connection is being intercepted by the hackers, who look for passwords, usernames, financial account log-in information, or other confidential data.
Is there any way for a user to detect this?
Yeah, make sure your WiFi connection uses decent authentication, like Cisco's LEAP.
Also, doesn't hurt as a corporate policy to mandate all WiFi access (or all incoming connections to the corporate network for that matter) is via VPN.
