Threat: Trojan.Win32.Phires.zm  
Vulnerability: Insecure Permissions  
Description: The malware creates an dir with insecure permissions  
containing a registry file with a ".desc" extension, under c:\ drive  
granting change (C) permissions to the authenticated user group. Standard  
users can rename the file dropped by the malware to disable it or replace  
it with their own. Then wait for a privileged user to logon to the infected  
machine to potentially escalate privileges.
