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).Read more

Technical Details
This is a worm written in Visual Basic Script language (VBS). It spreads through a network by coping itself to other computers in the network.
Upon being activated, the worm generates a random network IP address (for example 145.65.28.0), and tries to connect to all computers in this network. It changes the last octet of an address from 1 to 255 and tries to connect. If the connection is accepted, the worm copies itself to a connected computer on drive C: in the following folders:
C:
C:WINDOWSSTARTM~1PROGRAMSSTARTUP
C:WINDOWS
C:WINDOWSSTART MENUPROGRAMSSTARTUP
C:WIN95START MENUPROGRAMSSTARTUP
C:WIN95STARTM~1PROGRAMSSTARTUP
C:WIND95
If all computers in this network are inaccessible, the worm generates a new network IP address.
The worm creates a file "C:NETWORK.LOG". In this file, the worm writes all of its activities. The file content appears as follows:
Log file Open
Subnet : 145.65.28.0
Subnet : 23.44.93.0
Subnet : 50.112.201.0
Subnet : 176.3.138.0
Copying files to : \176.3.138.5�
Successfull copy to : \176.3.138.5�
The spreading ability of this worm is very low, because search of a victim computer takes a lot of time and most computers reject a requested connection.
