Macro.Word97.Antimarc

Description Macro.Word97.Antimarc

This virus infects Word97 documents and spreads via global electronic channels: chat-net mIRC and MS Outlook Express. This is the first known macro virus that uses mIRC and Outlook to spread infection. The virus contains the comments:
W97M/antiMARC by Lord Natas [Codebreakers 98]
with special thanks to Rhape79
"We're just the toys in the hands of another"

The virus code contains 15 macros in one module "Antimarc": antiMARC, mIRCDropper, OE, Delay, AutoClose, AutoExec, AutoOpen, FileClose, FileExit, FileSave, FileSaveAs, ToolsMacro, FileTemplates, ViewVBCode, FormatStyle.
The antiMARC macro is the main virus macro. Other ones are either do-nothing ones (AutoExec), or call this macro to infect Word97 documents. The mIRCDropper macro sends the infected documents to chat-network, the OE macro sends the infected message by using Outlook Express.
The virus replicates in Word environment on activating of any auto-macro except AutoExec, i.e. the virus infects the global macro area and documents on documents opening, closing, saving, saving with new name, on entering the Tools/Macro, File/Templates and other menus. To copy its code the virus uses export/import functions via the SYSTEMMICROSOF.386 file that is created in the Windows directory.
Depending on the system random counter the virus also executes its Chat and Outlook spreading routines. While sending its copy to the Chat the virus uses the MIRC32.EXE utility. It disables mIRC warning messages in the system mIRC C:MIRCMIRC.INI file, creates the infected file C:WINDOWSXXXPASSWORDS.DOC and the script C:MIRCSCRIPT.INI.
The virus script file contains the instructions that send the infected XXXPASSWORDS.DOC file to all users that join the Chat. If there is a message with "marcsux" substring, the virus sends to the host of this message the text: "#gotinfected777 X". The virus also sends the message to the Chat:
marc FuCk YoU FaScIsT
warblade STILL SUCKING MARC's COCK?? eh, sure you do!!
super Hey M0therfux0r, shove X/W up yer fat pimple-covered ass!
super 'We do not support the distribution of virii' - i guess you do now, bitch!
#gotinfected777 Kick Me! - I'm InFeCtEd!

While sending itself by using MS Outlook Express the virus creates random named infected file on the C: drive, selects 20th address in Address Book, creates a new message, fills it with random letters, attaches the infected file and appends the footer line:
J97Z/nagvZNEP ol Ybeq Angnf [Pbqroernxref 98]

This procedure is not language independent and does work only under German version of Outlook Express.

Macro.Word97.Antisec

Description Macro.Word97.Antisec

This macro virus infects MS Word documents and normal.dot template files. The virus itself is a macro named 'AntiTheSecond' and it seems that the author intended it to act as an antivirus against the macro virus TheSecond.
When an infected file or template is opened, the virus creates an export file named Anti.tmp in the MS Word start directory. The macro code is saved in this file. The virus then checks all MS Word documents which are currently open for the macro module of TheSecond virus. If this module is detected, the virus will cause a MessageBox to be displayed. The MessageBox contains the following text in Russian:
ïÂÎÁÒÕÖÅÎ ×ÉÒÕÓ The Second × ÄÏËÕÍÅÎÔÅ <ÉÍÑ ÆÁÊÌÁ> !
Translation: The Second has been detected in the document 'name of file'!
It then deletes the contents of the virus module, without deleting the module TheSecond (which is a type of vaccine for files). If this is successfully completed, a MessageBox in Russian will be displayed on the screen:
äÏËÕÍÅÎÔ <ÉÍÑ ÆÁÊÌÁ> ×ÙÌÅÞÅÎ!
Translation: The document <name of file> has been cleaned!
If the document does not contain the virus TheSecond, Antisec will infect it by writing its code to the document from the file Anti.tmp. A MessageBox in Russian will then be displayed on the screen:
áÎÔÉ×ÉÒÕÓ ÄÏÂÁ×ÌÅÎ × ÄÏËÕÍÅÎÔ <ÉÍÑ ÆÁÊÌÁ> !!!
Translation: An antivirus has been added to the document <name of file> !!!
