The Metasploit CTS/RTS flood attack

In a wireless medium, collisions can degrade the performance of the network. In order to avoid collisions, clients transmitting at the same time, wireless clients, and access points use CTS/RTS, clear to send, and request to send frames before transmitting data. Whenever a wireless client wants to send data, it reserves the medium by sending RTS/CTS frames. In simple terms, when a wireless client is about to send some data, it notifies other devices on the network that it's going to send data and asks others to wait for some time before attempting to transmit themselves. Other stations respect the announcement and wait until the transfer is complete. An attacker can use these unauthenticated frames and create a denial of service condition on the target network.

By continuously sending RTS/CTS frames to other devices on the wireless network, the attacker tries to reserve the medium, thus creating an idle network. In practice, this does not ultimately lead...
