An attacker is trying to compromise a wireless network that has been secured using WPA2-PSK and AES. She first tried using AirSnort to capture packets, but found that she couldn't break the encryption. As an alternative, she used software to configure her laptop to function as an access point. She configured the fake access point with the same SSID as the wireless network she is trying to break into.
