Description: Welcome to Part 14 of the WLAN Security Megaprimer! Please start this series by watching Part 1http://www.securitytube.net/video/1756, if you have not done so already.
In this video, we will understand how WEP works. Almost all of us know that WEP is broken but still people use it off and on. The funny thing is that WEP cracking started as early as 2001! and still access point manufacturers seem to be shipping it. Once you have the right tools, WEP cracking is simple 5-10 minute exercise. However, it is important to understand how this protocol works. This will help us in understand why WEP is broken and also how attacks such as the Caffe Latte Attack, Hirte Attack, Chop-Chop etc. work!
We will also learn how to decrypt WEP packets using Wireshark and Airdecap-NG once we know the WEP key. In the next video, we will look at various tools and techniques used for WEP cracking.
