W97M.Gogaru.A

W97M.Gogaru.A is a macro which is coded to drop a password-stealing Trojan onto the system. It is first downloaded from a Web site as an .rtf document.

This macro was originally found on a user home page on a Russian Web site, and it was intentionally placed there by the author. The macro contains instructions to create and execute two files in the root of the drive C: S.bat and S.exe.



Downloading a template file and executing the macros within it by using an .rtf document is an example of a disclosed and publicized exploit. Microsoft has a patch which addresses this vulnerability. For more information, go to:
