This article is the first of a two-part series that looks at the new generation of WEP cracking tools for WiFi networks, which offer dramatically faster speeds for penetration testers over the previous generation of tools. In many cases, a WEP key can be determined in seconds or minutes. Part one, below, compares the latest KoreK based tools that perform passive statistical analysis and brute-force cracking on a sample of collected WEP traffic. Next time, in part two, we'll look at active attack vectors, including a method to dramatically increase the rate of packet collection to make statistical attacks even more potent.
