What are some of the tools used to perform WEP attacks?
What will be an ideal response?
WEP attacks can be performed through any one of a number of tools that are freely available on the Internet. Some of the best known include AirSnort, Aircrack, ChopChop WEP Cracker, and WEP Crack. However, these tools require a certain degree of computer experience to use. Only certain wireless NIC adapter cards with specific drivers can be used, and almost all of these tools were developed under the Linux operating system and are designed to function under Linux. Although a few of these tools have been ported to the Windows operating system, they require special supporting software packages to properly function. Also, the length of time needed to capture enough packets to break WEP can be several (5 to 7) hours, depending on the volume of traffic.
