Who is Vulnerable?
Vulnerability Description	Ares Galaxy is an open source peer to peer file sharing application that uses its own decentralized supernode network. The latest versions also support the BitTorrent protocol. The use of Ares Galaxy may circumvent the organizational security policy. There are cases in which certain traffic, although not intended for malicious use, is very unsafe, since it may transfer shellcode which is undetectable by IPS.

In some cases, existing downloads will continue to run.This protection is able to detect peer to peer traffic regardless of the TCP/UDP port that is being used to initiate the peer to peer session.
