Is there a wireless sniffer that can decode and display graphics in realtime

I vaguely remember on The Screensavers when they showed a program on the mac that could sniff the wireless packets being transfered in an unsecured network and was able to display what was being downloaded by clients in realtime.

I'll be doing a workshop on wireless security and I'd like to be able to display to others the risks of using a wireless network as opposed to one that encrypts transfers from the AP and client.

If it helps, I remember that the program was for OS X though I'll be using my laptop, a Windows XP system to give the presentation. If possible, I'd like to find a program for Windows XP that can do this although I'd also be willing to install a virtual machine if Linux is needed or I can have a friend of mine assist me with his Mac during the workshop.

Any help is appreciated. Thanks.
 
Hello? Beuller? 🙂

If it helps, I saw the program being showcased o The Screensavers after it had moved to G4 and before Kevin Rose left. They had it running on a Mac laptop and all the program did (AFAIK anyway) was display image data that was being sent to clients who were browsing the net. For instance, if someone in the other room was looking at a gaming site, the mac would probably pick up ads, screenshots, etc, of various games and what have you. Whatever website the client was looking at, this program would sniff out the image data and display it.

I'm doing the workshop with or without the program but I feel like it would be a fantastic example of how your data is basically sent out for anyone to pick up and view when connected to an unencrypted network. In particular, I've seen people purchase things at coffee shops with their credit cards and I'd like to use this program as a showcase as to why that's a bad idea.
 
If No one posted anything in 30 hours, probably No one is aware of such an "Animal".

Unlike Beuller, people here or not shy about what they know.

This is not exactly what you are looking for, but if you want to demonstrate the idea that packets can be intercepted and translated into meaning info it might help, http://www.effetech.com/sniffer/
 
run a sniffer, log into a router or an http (non SSL) based site. Show the packet where it actually transmits the username and password.
 
I didn't see the thread earlier or I would have posted:
tcpxtract might be able to do it. Can't remember.
etherpeg does it on the Mac.
driftnet works just fine in Linux and *BSD. 🙂

EDIT: And yes, it's kind of creepy the kinds of things people download on a coffee shop open wireless connection... :evil:

Etherpeg looks exactly like the program they had on the show.

It looks like those were the programs I was looking for. I may just setup vmware so I can display it in my presentation although I do have someone helping me who has a mac as well.

Thanks, I was worried I'd never find it.

It took me a bit to remember what they were, I haven't used them in a while. But they make a great demonstration tool.
 
how can i get tcpxtract to work under windows, i cant compile it without an error under borland c++builderX. is there an exe somewhere or should i do it under linux for the compile and use?

Linux would be a better solution. It generally is. Did you try compiling it under cygwin?
 
Ok. Really dumb question.

Aside from a few LiveCDs, I've never used Linux extensively. I tried to use tcpxtract in a ubuntu distro but couldn't figure out how to actually use it. I typed "tcpxtract -d eth1" at the terminal since it detected my wireless adapter as device "eth1" but it said that it wasn't permitted to access the device. 🙁
 
What about ethereal (now wireshark). It won't display graphics in realtime, but you can demonstrate a capture in real time and extract the graphics. They have a demonstration capture on their website from which you can extract a jpeg.

It also runs natively on windows.
 
i would like a compiled version of one of those that are exe, i'll take someone's word that it does what it says. 😉 i eventually found ethereal and mrtg as an exe, already compiled and working to download, but can't find any windows based equivalant of tcpextract or driftnet. i heard pikachu was the windows equivant in exe form but that site went down and i can't download it since there were no other sites hosting it.

Why not just run a better OS?
 
well because the majority uses windows xp, and i'm going to use it for ease of use since its everywhere on every pc i goto... and unless i run knoppix from my one cd, or put linux in a virtual pc on my laptop that i bring around, i'm going to be using windows on other computers.. either way, i would need to compile it under linux to use it, and i didn't have much luck recompiling the kernel when i did that 2 years ago, so i'm not confident in my compiling abilities under linux.
 
EtherWatch is basically driftnet for windows, precompiled as an exe, it worked when i tested it a little this morning, but you can't do this to a switch or when your the only one on a wlan, so i tested my traffic, and saw some pics and google searches showing up under etherwatch. didnt show every pic though which let me down, but at least i found something for windows that is compiled.
