Wireless networks are most common type of networks found in today's communication. Advantage of these wireless networks (IEEE 802.11) is that physical connection is not required for being a part of a network and at a same time no physical access is required to crack and penetrate such a network. The three main security algorithms which are implemented for the security of this protocol (WiFi) are WEP, WPA and WPA2. In this paper the authors discuss an attack on the WiFi networks to crack its password and gain unauthorized access to the network.
