Evil Twin

Evil Twin

A wireless access point or computing device that spoofs the legitimate access point’s SSID or uses a similar name to another network. This can be used to instigate a man-in-the-middle attack where wireless communications between a client device, such as a laptop or smartphone, are intercepted by the attacker, resulting in stolen data, passwords or credit card numbers. During IT security awareness training, users should be reminded of the importance of using bona fide Wi-Fi networks and VPNs when accessing the internet in public places or whatever their IT security policy deems safe.
