Re: [Full-Disclosure] Blocking Music Sharing.

[Scott Manley <djsnm@xxxxxxxxx>]

Snort rules and port blocking of non-essential services are all very 
well but they'll never stop anything - anyone remember the CDC's much 
publicised 'Peek-a-Booty' I remember them commenting that it was going 
to run over SSL on port 443 by default - after all which sysadmin is 
going to shutdown SSL traffic on 443? And since it's SSL you're not 
going to be able to sniff it.

I'm not sure if there are any more popular p2p apps that could get away 
with this trick, so it's not a real threat for the moment.

You might want to look at vulnerability scanners, detecting the running 
client on a host machine is a good possibility, although many p2p 
clients can operate without listening ports on every host.
