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.

Description 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).


Win32 is an API on Windows NT-based operating systems (Windows XP, Windows 7, etc.) that supports execution of 32-bit applications. One of the most widespread programming platforms in the world.


Malicious programs in this family are used by cybercriminals to install additional software on the infected computer.

The malicious program copies its executable file to a temporary folder on the user’s computer and modifies the operating system registry, enabling the malware to run automatically after the user logs in to the system. The malware decrypts itself, performs extraction from its resources section, and launches other malicious programs.
