BE WARNED!!! A FRIEND OF MINE HAS BEEN HIRED BY THE RIAA TO COME UP WITH A SNEAKY WAY TO FIND OUT WHO YOU ARE!!!!!
He's writing some stuff which fiddles the registry of kazaa, kazaa lite, etc so that it shares the whole hard drive, and allows anyone to connect to your box.
THEN.. it makes a listing of all mp3's on your pc, grabs your ip addy, does a traceroute to an RIAA server, zips it up, and stores it as yourcomputername_436.mp3
THEN.. they just does a quick search for *436.mp3 over the net, and whammo.. they get the zip file.
My friend is outsourced from India to do this job. I cannot release his identity, because of security reasons. But now you know!
The only way to keep yourself safe is NOT to download any new versions of software, and not to download software from Kazaa!!!
