Parent class: VirWare
Viruses and worms are malicious programs that self-replicate on computers or via computer networks without the user being aware; each subsequent copy of such malicious programs is also able to self-replicate. Malicious programs which spread via networks or infect remote machines when commanded to do so by the “owner” (e.g. Backdoors) or programs that create multiple copies that are unable to self-replicate are not part of the Viruses and Worms subclass. The main characteristic used to determine whether or not a program is classified as a separate behaviour within the Viruses and Worms subclass is how the program propagates (i.e. how the malicious program spreads copies of itself via local or network resources.) Most known worms are spread as files sent as email attachments, via a link to a web or FTP resource, via a link sent in an ICQ or IRC message, via P2P file sharing networks etc. Some worms spread as network packets; these directly penetrate the computer memory, and the worm code is then activated. Worms use the following techniques to penetrate remote computers and launch copies of themselves: social engineering (for example, an email message suggesting the user opens an attached file), exploiting network configuration errors (such as copying to a fully accessible disk), and exploiting loopholes in operating system and application security. Viruses can be divided in accordance with the method used to infect a computer:- file viruses
- boot sector viruses
- macro viruses
- script viruses
Class: Virus
Viruses replicate on the resources of the local machine. Unlike worms, viruses do not use network services to propagate or penetrate other computers. A copy of a virus will reach remote computers only if the infected object is, for some reason unrelated to the virus function, activated on another computer. For example: when infecting accessible disks, a virus penetrates a file located on a network resource a virus copies itself to a removable storage device or infects a file on a removable device a user sends an email with an infected attachment.Read more
Platform: MSWord
Microsoft Word (MS Word) is a popular word processor and part of Microsoft Office. Microsoft Word files have a .doc or .docx extension.Description
Technical Details
This is German-specific Word macro virus. It contains six macros, some macros have random selected names:
Documents MICROSOFT.DOT (infected Word)It infects the system on opening and on closing an infected document. To affect Word the virus creates the infected MICROSOFT.DOT template in the Word startup path. Documents get infected when saved with a new name.dateispeichernunter extrasmakro extrasmakro dateischliexen dateidokvorlagen dateidokvorlagen autoopen
The infection-routine is placed in a macro with a random name. This macro is encrypted in documents and is decrypted in case of need. The names of macros (random names) are stored in documents' variables (in case of documents), in case of MICROSOFT.DOT file (infected system) they are stored in the WIN.INI file in the section [embedding] in the items vxdRNDM, TaskRNDM, SystemRNDM.
On the 30th of any month the virus displays the message:
Leeglize Cannabis !! R.M.M (C) by MaD KiFFeR 05.09.98On the 15th the virus appends to the AUTOEXEC.BAT file the commands that cyclically display the text:
