WEP-cracking

The process for WEP-cracking is very similar to that which was utilized for cracking WPA. Identify the target network, capture traffic, which includes the authentication mechanism, and then point a brute-force attack to reverse the key. There are some differences, though. As opposed to WPA-cracking, where all we had to do was capture the four-way handshake, in WEP-cracking, we have to ensure we gather enough of the Initialization Vectors (IVs) to properly crack the WEP key. Although this may seem like a tall order, techniques are available to force this process and make the time necessary to sniff traffic as short as possible:

  1. To start the process of cracking WEP, we put our wireless card into monitor mode in the same fashion ...
