Bagle.CZ - New variant using CPL extensions
This new variant was massively spammed via email and while the downloader component doesn't appear to be working, this new variant can deactivate existing AV or FW software installed on the PC. The CPL extensions are typically found inside of a zipped archieve. This modified variant bypasses detectability in most AV products and users should be cautious in handling email messages.
McAfee information on this massively spammed variant
Multiple new variants of this threat were recently mass spammed. Filenames include 1.cpl and price.cpl and may arrive in a ZIP file named newprice.zip , price_09.zip, price some number.zip , etc. The variants seen thus far are non functional, and deemed a low risk. The first such variant drops a corrupt file (ceeweewe.exe) to the %windir%. The corrupt file is detected as W32/Bagle.dam. Detection will be enhanced in the 4580 DAT release to detect and delete these newly discovered damaged variants. This is a generic detection covering many variants of the W32/Bagle@MM virus when sent in "CPL" format.
