Macro.Word.Ato

Tuesday, January 20th, 2009

Details
Macro.Word.Atom

These viruses contain four macros: Atom, AutoOpen, FileOpen, FileSaveAs, and infects Word while loading an infected document (AutoOpen).
The viruses infect files in two ways: while opening a file (command File/Open, macro FileOpen), and while saving a document with new name (command File/SaveAs, macro FileSaveAs).
While infecting a document while saving it with new name (FileSaveAs) the virus checks the system time. If the value of seconds is equal to 13 the virus set the password ATOM#1 for this document. The virus cannot set the password if the file is already infected – Word displays the WordBasic error message.
While opening an infected document on 13th of December the virus deletes all files in the current directory. It seems that the system has to display the error message while deleting opened files.
“Atom.a”-related macro viruses differ from “Atom.a” only by placing their WordBasic text strings in virus source code. “Atom.g” is “Atom.a”, translated to German – it contains macros: Atom, AutoOpen, DateiÖffnen, DateiSpeichernUnter.

Macro.Word.Anti-IV

Monday, January 19th, 2009

Details
Macro.Word.Anti-IVX

It is not a dangerous semi-polymorphic macro virus. In infected documents it contains one macro AutoOpen that infects global macros area while opening an infected document. In infected NORMAL.DOT in contains two macros. The first macro is a copy of AutoOpen macro and has a random selected name. The second macro has the name FileSaveAs and infects documents that are saved with new name.
The virus is semi-polymorphic – while copying its AutoOpen macro it renames its internal values to other names, generates random name for copy of AutoOpen macro. While creating FileSaveAs macro the virus inserts commands that are selected from several variants and inserts random selected comments.
While infecting global macros area the virus creates the IVX.NOT file in the directory of the host file and writes the text to there:
IVX detects all macro viruses, past, present, and future.

It adds the command to the C:\AUTOEXEC.BAT file that clears the Read-Only attribute of NORMAL.DOT file:
@ATTRIB -R WordDirectory\NORMAL.DOT > NUL”
