Brief Description 

    

Manymize is a worm that reaches computers hidden in an e-mail message with random subject and text. However, it always includes the following attached files: (MI2.EXEMI2.WMV, MI2.CHM and MI2.HTM).

This worm activates automatically when the message is opened or just viewed through Outlook’s Preview Pane. In order to do so, it exploits a vulnerability (Exploit/iFrame) found in Internet Explorer 5.01 and 5.5, which allows files attached to an e-mail message to run automatically.

Manymize also takes advantage of another vulnerability: Media Player Unchecked Buffer.

Visible Symptoms 

    

Manymize is difficult to recognize at first sight, as it arrives in an e-mail message with variable characteristics. The subject can be any of the following:

Hi %recipient’s name%
Dear %recipient’s name%
Hello %recipient’s name%
My friend, %recipient’s name%
How are you !! %recipient’s name%
