Macro.Word97.Afet

Macro.Word97.Afeto

This is an Internet worm that spreads through e-mail by using Microsoft Outlook. This worm is Word macro-program written in VBA (the macro-language for Microsoft Office).
When an infected document is opened, the worm macro gains contorl, scans all local drives and looks for a JPG-file less than 50,000 bytes in size. The first found file is then inserted in an active document (current infected document). The worm then creates new messages and sends them. New messages are created for the first eight messages in the MS Outlook “Sent items” folder. The messages are created according to the following involved rules:
as an address in the field “To:” the worm sets the address from a message in the “Sent items” folder
as a subject and body message, it sets the subject and body from next message in the “Sent items” folder
an active document with the worm body is attached to the message
For example, the “Sent Items” folder contains the following messages:
Message 1
To: name1@domen1.com
Subject: Hello!
Text: Do you remember me?
Message 2
To: address2@host2.com
Subject: Good bye.
Text: Today I’m leavingall
Message 3
To: nick3@server3.com
Subject: News.
Text: Great news. …
Outgoing messages (in folder “Outbox”) with a worm will appear in the following way:
Message 1
To: name1@domen1.com
Subject: Good bye.
Text: Today I’m leaving…
Message 2
To: address2@host2.com
Subject: News.
Text: Great news.
Message 3
To: nick3@server3.com e.t.c.

Attach: Infected document

An infected document contains a JPEG file that has been selected by the worm as well as a worm macro-program.
In this way, the worm sends an infected message to the first eight recipients, whose addresses have been found in the folder “Sent items”. But for all this, in many instances, the worm breaks confidential correspondence.

Macro.Word.Zoolo

Details
Macro.Word.Zoolog

This macro virus contains one macro AutoOpen and replicates on opening documents. The virus deletes all macros in global macros are (NORMAL.DOT). It writes the line “beep=ZOOlog” to the Windows WIN.INI file and detects itself in the system by reading this string. The virus detects already infected documents by “Document Author” string - “ZOOlog”.

Macro.Word.ZM

Thursday, July 26th, 2007

Details
Macro.Word.ZMB

This is a German Word macro virus. It contains four macros: AutoOpen (NORMAL.DOT - ZMB), ExtrasMakro, DateiDrucken, DateiSpeichern.
The virus infects the global macros area (NORMAL.DOT) on opening an infected document (AutoOpen) and writes itself to documents that are saved (DateiSpeichern).
This is stealth virus: it replaces Extras/Makro (Tools/Macro) menu with another one. Depending on the system random counter the virus replaces the words while printing documents.
On March 31st it erases the CONFIG.SYS, AUTOEXEC.BAT files and displays the MessageBox:
Osterhasenpolizei
Hallihalloall.
Ich bin der Osterhase und sage Dir, dax man
an Ostern keinen Computer benutzen soll !!

Details
Macro.Word.Zashib

This virus contains four macros: AutoOpen, Knell, Mutagen (Normal:FileOpen), Zashib (Normal:FilePrint).

While printing a document at 16:xx the virus appends to the end of document a text in Russian.

Macro.Word.Xenixo

Wednesday, July 25th, 2007

Details
Macro.Word.Xenixos

It is encrypted virus. It contains the macros:
Drop, Dummy, AutoExec, AutoOpen, DateiÖffnen, ExtrasMakro, DateiBeenden,
DateiDrucken, DateiSpeichern, DateiSpeichernUnter, DateiDruckenStandard.

In some cases it sets the password “xenixos” for infected documents, displays the message:
Diese Option ist derzeit leider nicht verfügbar.
Fehler

While printing the documents it appends:
Brought to you by the Nemesis Corporation, L1996

On 1st of may the virus writes the string to the AUTOEXEC.BAT file:
@echo j|format c: /u >nul

This virus also launches “Neurobasher.b” multipartite virus. To do that the virus creates the C:\DOS\SCRIPT.SCR file, and writes hexadecimal dump of that virus into there. Then the virus creates the C:\DOS\EXEC.BAT file, and writes the strings into there:
@echo off
debug < script.scr>nul
rem debugger.com
echo @c:\dos\debugger.exe>>c:\autoexec.bat
del c:\dos\script.scr
del c:\dos\exec.bat

Then the virus executes that file. As the result DEBUG.EXE creates the DEBUGGER.EXE file, and C:\AUTOEXEC.BAT has new string at its end:
@c:\dos\debugger.exe

So, the last command of AUTOEXEC.BAT launches dropper of “Neurobasher.b” virus.

Macro.Word.Wazz

Tuesday, July 24th, 2007

Details
Macro.Word.Wazzu

This virus contains only one macro autoOpen and infects files when MS Word opens them, and copies its macros to Global area (NORMAL.DOT) when MS Word opens an infected document. The virus is not encrypted and may be easily detected by scanning for text strings:
RndWorddo
wazzu do
RndWorddRgV

After infecting a document or installing into the system the virus takes a random selected word from document and moves it to random selected position. The virus repeats that up to three times depending on the random counter. Then it also depending on the random counter inserts the string “wazzu ” at random selected position within document.
In detail: the virus has three subroutines in its macro:
MAIN - it is main routine and it takes control when autoOpen
macro is executed
Payload - is called by MAIN, replaces words and inserts “wazzu”.
RndWord - is called by Payload, sets random selected position
within document

The virus modifies the document with the probabilities (p): replacing words - three times with p=1/5, inserting “wazzu” - p=1/4.
Wazzu-related viruses
The original “Wazzu” (”Wazzu.a”) virus is one of the most widespread viruses on the world. The possible reason is that this virus was placed on the Microsoft WWW site, infected documents also were (are) distributed on several CD disks. As a result there are several dozens of related viruses, and the number of such related viruses is increasing every month. Below short descriptions are given, to name viruses CARO standard names are used (AVP does detect and disinfect majority of these viruses as “Wazzu.a”).
“Wazzu.b,i” differ from original one only by included comment:
< - - - - - - here ’s the payload

“Wazzu.c,t,ac” do not manifest themselves in any way - they have no Payload subroutine (RndWord subroutine presents in virus, but is never called).
“Wazzu.d,f,q,w,ad” do not have both Payload and RndWord subroutines. “Wazzu.f” is a shortest virus in the family - its code (binary data in infected file) has only 318 bytes of length.
“Wazzu.e,h” are encrypted variants of original “Wazzu”. “Wazzu.h” is slightly corrupted and may halt MS Word or cause an error message.
“Wazzu.g,r” are encrypted viruses. “Wazzu.g” contains EatThis subroutine instead of original Payload. With probability 1/10 these viruses display a MessageBox with the text:
Microsoft Word
This one’s for you, Bosco.

“Wazzu.k” is corrupted “Wazzu.a”.
“Wazzu.l” do not have any subroutines in macro except MAIN. With probability 1/10 it appends the string ” wazzu!” to the end of document.
“Wazzu.m,s” have no Payload subroutine, but call it. That will cause Word’s error message.
“Wazzu.u,aa,ad” are the same as “Wazzu.a”, but do not insert the “wazzu” string.
“Wazzu.x” does not contains any subroutines except MAIN. It contains the text:
The Meat Grinder virus - Thanks to Kermit the Frog,
and Kermit the Protocol

“Wazzu.y,z” are the same as “Wazzu.a”, but code of these virus is slightly modified, for example all TAB (09h) symbols are replaced with 8 spaces in “Wazzu.y”.
