The tools in the suite allows us to perform various actions such as packet monitoring in the environment, montoring of specific access points, de-authentication attacks on access points, and cracking of WEP and WPA PSK (WPA 1 and 2) passwords.</p> <p><img src="http://www.aircrack-ng.org/resources/aircrack-ng-new-logo.jpg" alt="aircrack-ng"></p> <p>In this post I will explain on how to perform these actions.</p> <h2 id="wireless-card-monitor-mode">Wireless Card Monitor Mode</h2> <p>Before we begin it is crucial that we change the mode of our wireless network card to <strong>monitor mode</strong>. BY default, our wireless network card's mode is <strong>managed mode</strong>. In managed mode, the network card generally only listens to packets addressed to the card, whereas in monitor mode it will hear <strong>every packet in the air</strong>.
