Join Lisa Bock for an in-depth discussion in this video Using Wireshark to crack WEP, part of Learning Cryptography and Network Security.
We talked about WEP and why it is weak.…Now I'm gonna demonstrate this to you…using Wireshark,…a free protocol analyzer.…I'm not gonna show you how to use Wireshark.…You can visit my course on Wireshark…if you wanna follow the details on that.…For now, I'm gonna go to this website.…A blogger shares his experience…in a challenge in extracting the WEP key.…I downloaded the capture file found here…and we're gonna go into Wireshark and take a look at it.…
Now what we have here is a capture.…I'm gonna go down to the bottom of the screen…and you can see there is a healthy amount…of Packets that are captured.…Now when you do any type of penetration testing…on your network,…there are a plenty of free software tools,…such as Kali Linux or Aircrack…that can be used to recover the WEP key…after intercepting and analyzing…only a small amount of WEP traffic.…Now we're gonna take a look.…As you can see,…we have a lot of captured packets here,…but what I'm gonna go to is frame 30…and I'm just gonna jump to that…and I'm gonna work with this frame…
