Hackers Snatch Data From Bogus Wireless Access Points
Contributed by: G3nu1n3, at 1/21/2005 04:58:00 PM.

An "Evil Twin" that hijacks unsuspecting wireless transmissions is the latest security bugaboo, academic researchers in the U.K. asserted Thursday. But the idea is anything but fresh.

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.

"Users think they've logged on to a wireless hotspot connection when, in fact, they've been tricked to connect to the attacker's unauthorized base station," said Nobles in a statement. "The latter jams the connection to a legitimate base station by sending a stronger signal within close proximity to the wireless client " thereby turning itself into an 'Evil Twin'."

Internet Security Systems, for instance, published a wireless FAQ over two years ago that mentions this threat (as well as a host of others.)
