EvilAP_Defender is the leading open source, enterprise-class tool to discover and prevent Evil Twin Access Points (APs) from attacking wireless users. The Q-WiFi can discover and provide an email alert when an Evil Twin is discovered. In addition, it can perform a Denial of Service (“DoS”) attack to prevent the legitimate WiFi users from connecting to the Evil Twin AP. This can give network administrators and/or law enforcement time to locate and remove the Evil Twin AP. N.B. The DoS feature only works if the Evil Twin and legitimate AP have the same SSID but different BSSID, or is running on a different channel. (The BSSID – Basic Service Set Identifier - is the AP’s MAC address.) This prevents accidently crippling a legitimate AP. Whitelisting is done via a wizard during installation in order to recognize and allow legitimate Wireless Access Points (APs).
