Parent class: TrojWare

Trojans are malicious programs that perform actions which are not authorized by the user: they delete, block, modify or copy data, and they disrupt the performance of computers or computer networks. Unlike viruses and worms, the threats that fall into this category are unable to make copies of themselves or self-replicate. Trojans are classified according to the type of action they perform on an infected computer.

Class: Trojan

A malicious program designed to electronically spy on the user’s activities (intercept keyboard input, take screenshots, capture a list of active applications, etc.). The collected information is sent to the cybercriminal by various means, including email, FTP, and HTTP (by sending data in a request).

Description

Technical Details

This is a Trojan horse written as a MS Word97 macro-program. When it is activated, it appends to the end of a AUTOEXEC.BAT file a set of commands that delete all data on the C:,D:,E: drives. It then displays the following messages:

World War starting now!
Tvangeste v 1.0
3rd World War

It then goes into an endless loop displaying the following message:

3rd World War

Macro.Word97.Trojan.Tvangeste.b

This macro-Trojan saves the copy of an infected document with the name "C:Program FilesMicrosoft Office?�"--�kafeln.dot" and appends to the end of AUTOEXEC.BAT file the commands:

cd C:Program FilesMicrosoft Office?�"--�del normal.dot
ren kafeln.dot normal.dot

In this way, this Trojan tries to replace a normal template with an infected one, but it works only in case the Russian version of MS Word is installed, and the templates directory is "C:Program FilesMicrosoft Office?�"--�".

The Trojan also appends to the AUTOEXEC.BAT file the commands:

md c:atp_tour
md c:atp_tourkafelnik.001
md c:atp_toursampras.002
md c:atp_tourcorretja.003
md c:atp_tourrafter.004
md c:atp_tourmoya.006
md c:atp_tourhenman.007
md c:atp_tourrios.008
md c:atp_tourphilipou.009
md c:atp_tourkucera.010
md c:atp_tourkrajicek.005
subst k: c:atp_tour >nul

Then it displays messages in Russian and:

Tvangeste v 2.0
Kafelnikov
