Beware the Evil Twin
Friday, January 21st, 2005"Evil twin hot-spots present a hidden danger for Web users," said Phil Nobles, an academic researcher who specializes in wireless Internet and cybercrime. "Because wireless networks are based on radio signals, they can be easily detected by unauthorized users tuning into the same frequency."
Once an unknowing user has connected to an evil twin, a hacker can intercept transmitted data. Users are invited to log into the evil twin with bogus log-in prompts and can be lured into passing sensitive data such as user names and passwords.
This vulnerability seems to only effect public hotspots, and not your private WLAN, at least as long as your private WLAN is using some sort of encryption so that clients won’t connect to "Twins."
