WiFi Beaconing: A Way to Save Lives via Beacon Flooding. Beacons flood WiFi networks to tell any listening devices that this SSID is available and has particular capabilities. Each SSID on each band broadcasts a unique beacon frame. Beaconing is just an AP setting up multiple SSIDs purposely to make each of these different SSIDs an “independent” network. This means that we can broadcast hundreds or even thousands of fake access points and their names when they search for WiFi to connect to. It can be used to exfiltrate or leak data.
