A new open-source tool can periodically scan an area for rogue Wi-Fi access points and can alert network administrators if any are found.
The tool, called EvilAP_Defender, was designed specifically to detect malicious access points that are configured by attackers to mimic legitimate ones in order to trick users to connect to them.
These access points are known as evil twins and allow hackers to intercept Internet traffic from devices connected to them. This can be used to steal credentials, spoof websites, and more.
Most users configure their computers and devices to automatically connect to some wireless networks, like those in their homes or at their workplace. However, when faced with two wireless networks that have the same name, or SSID, and sometimes even the same MAC address, or BSSID, most devices will automatically connect to the one that has the stronger signal.
