US-CERT is aware of continued exploitation of insecurely stored passwords in Group Policy Preferences, due to 
incomplete implementations of Microsoft Security Bulletin MS14-025 [ 
http://technet.microsoft.com/library/security/ms14-025 ]. Systems may still be vulnerable to exploitation if 
administrators have not cleared all previously stored passwords from their environment. An attacker may decrypt these 
passwords and use them to gain escalated privileges.

US-CERT strongly recommends that administrators employ the PowerShell script provided in Microsoft  Knowledge Base 
Article 2962486 [ http://support.microsoft.com/en-us/kb/2962486 ] and follow the included instructions for clearing all 
"CPassword" preferences from their environment.
