Remote Access Trojan: An Overview

Remote Access Trojan, commonly known as RAT creepware, is a malicious program that often makes its way into your PC without you realizing it, starts living in it unauthorized, and hands over remote access to the user who has targeted you. 

Usually, the Remote Access Trojan, like any other trojan virus, is induced in the PC through third-party software and downloaded files. Files from unknown sources, such as email attachments, torrent files, or bundled software from third-party platforms, are the primary source of remote access trojans on any system. 

These programs are highly risk oriented as they try to root themselves in the core of your system, gaining access to all your data. There have been incidents when the remote access trojans have created their own botnet by spreading throughout the network that an affected PC uses.
