OVERVIEW:

        AusCERT is aware of new variant of a Trojan designed to steal 
        confidential information.


IMPACT:

        A user who clicks on a link in an unsolicited email, may result in 
        the installation of a credential stealing Trojan. The links in the 
        email directs users to malicious web sites which attempts to 
        exploit vulnerabilities in Internet Explorer, Mozilla Firefox and 
        Opera web browsers.

        At the time of writing, this Trojan executable is not well detected
        by many Anti-virus software packages.


MITIGATION:

        The spam email contains links to one of the following sites:

          orionfinanceinc,org
          orionfinanceinc,net
          orionfinanceinc,com
          orionfinanceinc,info
          bristolantiquesale,com
          bristolcollections,com
          orionfinanceinc,net
          orionfinanceinc,info
          orionfinanceinc,com
          orionfinanceinc,org
          bristolantiquesale,com
          bristolcollections,com
          www.bristolcollections,com

        All these sites linked to malware being hosted on the web site:

          http://bettarchilli.com/...

        AusCERT has contacted the site operator and had the malicious 
        content removed. This has since been moved to:

           hxxp://bawazeerest,com/

        AusCERT is currently working on removing the malicious content from 
        this site.

        AusCERT recommends that administrators examine sources of recent 
        internet traffic to these sites in order to identify potentially 
        compromised systems.

DETAILS:

        The Trojan email has a subject line of one of the following 
        variations:

            "I SENT YOU AN ECARD FROM AMERICANGREETINGS.COM"

        An example of the message body is:
            
            To view your eCard, choose from the options below. 

            Click on the following link. 
            http://www.americangreetings.com/ecards/view#pd?i=439899392&m=2157&rr=y&source=ag999
            Or copy and paste the above link into your web browser's 
            "address" window. 

            If you have any comments or questions, please visit 
            http://www.americangreetings.com/help/index.pd?source=ag999

            Thanks for using AmericanGreetings

        This Trojan uses a kit similar to "MPACK" malware hosting kit used 
        in recent attacks in Europe. For more information on MPACK see the
