The ZIP containing our presentation and the tool Ferret is on our website for download.
Remember that the purpose of the tool is to catch all the things you broadcast about yourself and correlate it. It's not to sniff passwords, exploit bugs, or otherwise catch things that the users aren't willingly broadcasting to the word. The things we catch, such as mDNS, are those things that computers make public in order to make communication easier. For example, iTunes broadcasts it's presence on the network so other people can listen to your music. This means it also broadcasts your name so they know who you are. We capture this "seapage" and show a picture of the many things you are "seaping".
The source code will also compile on Linux or MacOS with only a couple obvious modifications. Just "gcc *.c" the source code and fix __int64, stricmp, and memicmp. Again, you need libpcap for it to work. Add these when things don't work on gcc:
#define __int64 long long
#define stricmp strcasecmp
#define strnicmp strncasecmp
#define memicmp memcmp
