Description: Welcome to Part 15 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 finally reach the promised land – WEP Cracking 🙂 We talk about the various cryptographic vulnerabilities plaguing WEP and then look at how to crack WEP either Passively or Actively. In Active cracking, we use the popular ARP Replay technique to stimulate the network to send more data packets. We then move on to understand that packets with Weak IVs contribute towards key cracking, and once we have a sufficient number of them, tools like Aircrack-NG can comfortably crack the WEP key.
