Evil twin is a type of
Wi-Fi attack, similar in nature
to Web site
spoofing and
e-mail
phishing attacks. Here's how an evil twin attack
works:
A hacker sets its service identifier (SSID) to be the same as an
access point at the local hotspot or corporate wireless network. The hacker
disrupts or disables the legitimate AP by disconnecting it, directing a
denial of service against it, or creating RF interference around it. Users
lose their connections to the legitimate AP and re-connect to the "evil
twin," allowing the hacker to intercept all the traffic to that device.
