Virus writers are distributing viral source code with the latest version of the Bagle virus series, Bagle-AD. Much like its 29 predecessors, Bagle-AD
is a mass-mailing worm that is packed using UPX file compression. IT comes in the form of a password-protected .ZIP file, with the password included
in the message body as plain text or within an image. The ZIP file contains an executable with the extensions EXE, COM or SCR.
