Who is Vulnerable?
Vulnerability Description Foxy is a Traditional Chinese peer to peer file sharing application. It is widely used in Hong Kong, Mainland China and Taiwan. Unlike other peer to peer software, Foxy is very easy to use and has unlimited download capabilities. The use of Foxy may circumvent the organizational security policy. Foxy uses distributed topology, which means that the Foxy network relies on no tracker server to store file sharing information, instead the information is distributed among thousands of Foxy peers. This may result in a larger exposure of the shared files comparing to other peer to peer file sharing networks. The distributed topology also makes the revocation of a shared file in the Foxy network technically unfeasible. If some sensitive information has been shared in the Foxy network, it is impossible for the authority to technically stop it from further spreading. 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.

Protection Overview

This protection will detect and block the Foxy peer to peer application. IPS is able to detect peer to peer traffic regardless of the TCP port that is being used to initiate the peer to peer session.

In order for the protection to be activated, update your Security Gateway product to the latest IPS update. For information on how to update IPS, go to SBP-2006-05, click on Protection tab and select the version of your choice.
