We sniff the network to gather usernames and passwords, but we can also scoop up images. Lisa Bock shows how using Wireshark to capture and export images.
- [Instructor] When sniffing traffic, we know we can gather usernames and passwords, but we can also scoop up images. Capturing images can be done by using any number of tools. URLsnarf, WebSpy, Driftnet, or Wireshark. Let's take a look. I'm in Wireshark and I'm gonna launch a capture. Now I'm gonna go to one of our fictitious websites, the Landon Hotel.
Now I'll stop the capture, and I've stopped the traffic. Now I want to see the objects in the web pages that I've retrieved. I'll type http and as you can see, I got a number of objects here, some of which were the Landon Hotel. Now go to File and Export Objects, HTTP. As you can see, we have a number of different images. I can select one and say Save As.
I'll go to my image files, and it saved it as intro_attractions.jpg, Save, and then I can look at them later. So as you can see, you can collect images while sniffing using Wireshark.
