The fake beacon flood attack
Beacon frames are sent by access points at regular intervals, and client stations also send beacon frames when they are participating in ad hoc mode. A beacon frame contains important information about the network capabilities, such as channel information, timestamp, and configured SSIDs. Wireless clients can detect the presence of access points by listening for the beacon frames transmitted from Ops. They gather the information in Beacon frames to determine which networks are available and which access point to connect to. Typically, clients will choose to connect to an access point with a strong signal strength when all the other capabilities of the access point are equal. In this attack, an attacker fakes these beacon frames and sends them in large numbers to confuse the wireless clients; sometimes, this may make things difficult or prevent the wireless clients from connecting to their preferred networks.
In this attack scenario, we explore the fake beacon...
