Description

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Indication of Infection

On an infected system the virus deletes the FILE|TEMPLATE, TOOLS|MACRO and TOOLS|CUSTOMIZE functionality.

Each infected document will contain a text entry: KENNY-G S... for Summary|Author in FILE|PROPERTIES and GANSTA RAPPA for Summary|Keywords in FILE|PROPERTIES.

At an infected system on the 1st or 13th of a month several MessageBoxes like

- Mack Daddy X

Bad Boy, .., What u gonna do


OK

;

- The Gansta Rappa X

What u gonna do when they come for you


OK

are displayed. During the display it will set the FILE|SAVEAS password to 'gansta' . If you are affected please read "Add. Information". After setting the password two MessageBoxes like

- BMF X

The Gansta owns you ! ..


OK

are displayed.

Virus Characteristics

The virus consists of these macros: AUTOOPEN, FILESAVEAS, BADBOY, AUTOEXEC, FILENEW in an infected document. The virus becomes active by using Auto- and SystemMacros. All macros are encrypted using the standard Word execute-only feature. Meaning that the user is unable to edit or view the macro code.
