MacOS.Sevendust

There are 6 variants of this virus, including 4 polymorphic, encrypted ones. The differences are described below. What they have in common is that they all infect applications by modifying MDEF and MENU resources, and they can create a System Extension (with an invisible character at the beginning of the name so it loads early) or add an INIT resource to the System file. The existence of the extension is the easiest way of identifying its presence without using NAV.
